If it were not for the increasing maturity of notebook computer thinning technology in recent years, products of 15 inches and above have no portability to speak of, and the travel weight of more than 3kg (host + power adapter) is not acceptable to every user with mobile needs.
In addition to the design, configuration and service, more differences are implicit, and even if they are only compared to the configuration, their cost performance is not an order of magnitude.
As one of the three PCs, Dell has a rich and complete product line, in addition to the XPS, G, Inspiron and Alienware known to individual users, there are Also Vostro for small businesses , Latitude for medium to large enterprises and mobile workstation Precision. The masters who play today are from Latitude and Precision.
9000 series is the jewel of latitude crown, the young it is just the second generation of products, the product number at the same time upgraded to 9520, while maintaining a 15.0-inch screen, thin and light, strong, high quality, ultra-long battery life and other series features are retained and enhanced to a certain extent. Precision 7000 and 5000 series have a relatively long history, and the difference between the more powerful 7000 series and the more portable 5000 series is in the applicable use cases, and the product positioning is not high or low. Three products with different and irreplaceable qualities make up the "Liu Guanzhang" team of Dell's high-end business notebooks.
Latitude 9520：
Master brain, seek portability
Latitude 9520 processor Core vPro i7-1185G7 is the flagship product in the 11th generation Core TGL-U series, portable processor and machine design, not based on performance as a selling point, but more "smart" release energy. The body and top cover of the entire metal material CNC are the top stream of Dell's current process. Up to 18mm thick, 1.4kg weight, and optional touch or 4K screen, 32GB on-board LPDDR4x memory, 1TB M.2 2230 SSD and 88Wh large battery, 5G, SmartCard and other optional functions are readily available, while providing a 2-in-1 model that can flip the screen, such a high specification, strong material, large size screen can also maintain a lightweight body, is the latitude 9520 to meet the high requirements of portability of business people magic weapon.
Latitude 9520 pays more attention to the use of cleverness, providing users with excellent performance when it is critical, and long-term high-performance output is not what it is good at. In addition to deploying Dell Optimizer to provide intelligent performance optimization for specific applications, the Latitude 9520 focuses on extending the reach of intelligent applications across multiple business applications such as audio, video, networking, battery life, and more.
The machine can automatically sense that the user is approaching or moving away, waking up or locking the computer. Combined with Windows Hello facial recognition, the automatically on SafeShutter auto camera brings a completely different privacy and security experience. In a non-user-authorized state, SafeShutter uses the lens cover to automatically occlude the camera. When the user approaches the Latitude 9520, the host automatically wakes up from sleep, with a deliberately created crisp click, the lens cover automatically opens, the infrared fill light of facial recognition, the camera is synchronously lit with the indicator light, and the lens cover will be closed again after the recognition is completed (regardless of success or failure). In addition to the automatic switch, the user can also disable the camera continuously through the F9 shortcut key, and the lens cover cannot be opened. It is believed that with such a privacy and security design, users no longer have to stick a webcam with paper.
In addition, the Latitude 9520 has a charge-discharge mechanism that intelligently matches the schedule, which can fully charge the battery before you leave your desk, and when you don't have to leave for a long time, it will keep the battery non-full accordingly, extending battery life. The 88Wh large battery is paired with a 90W power adapter for a fixed combination, which can be fully charged in 1.5 hours, bringing more than 8 hours of battery life per day - higher frequency Core vPro i7-1185G7, 32GB of MEMORY, 1TB SSD, 4K 500lm screen. For example, switch to Windows 11's battery saver mode or long battery life mode, reduce screen brightness, and battery life exceeds 10 hours.
With the active care of the Latitude 9520, users worry less about the performance and status of the computer and can focus more on the work itself.
Precision 5560：
The main battle, the reliability of the plot
It seems that the Precision 5560, which also has a thin and light design, is a completely different experience to use, who called it Precision!
Although Precision still maintains the product sequence of 3, 5 and 7, the Precision 5560 has shifted from the traditional mid-range positioning to the portable workstation field, and the Precision 7560, which emphasizes the level of performance, has gone in a different direction, so it is not appropriate to divide the product grade with performance and configuration.
Compared with the Latitude 9520 with a 15.0-inch screen, the Precision 5560 maintains the tradition and breaks through to the greatest extent, with a 15.6-inch 3840× 2400 resolution 16:10 touch screen, optional high-performance, high-reliability platform including Xeon vPro (45W), ECC DDR4 memory, two memory slots, two PCI-E 4.0 SSD slots, 86Wh batteries, and 130W USB-C fast charging, 3 USB-C ports (two of which are Thunderbolt4/USB4), SD card slots, and best-in-class scalability.
In this case, the Precision 5560 maintains good portability, thanks not only to the ultra-narrow screen design on the 4 sides, but also to the widespread adoption of miniaturized MEMS components. For example, the camera module integrated in the upper edge of its 4.5mm screen includes 2 infrared emitters, ambient light sensors, RGB cameras, status indicators, proximity sensors, etc., and dual digital microphones are also hidden here. Even without using the standard fingerprint power button, the machine can automatically wake up and automatically log in to the system through Windows Hello Facial Recognition, improving the convenience of use.
Coupled with the 16:10 screen ratio, the lower edge of the Precision 5560's screen sinks further, rendering the effect that the entire B-side is a screen. The screen drive and high-voltage module are transferred to the inside of the fuselage. The figure above shows a comparison with the Precision 7560.
Precision 5560 has excellent portability, the entire C surface is made of carbon fiber woven material, thickness and weight are compressed, and even the thickness of the main machine can compete with the Latitude 9520, and in order to improve the strength of the fuselage, its C surface adopts a sandwich structure, and the carbon fiber material fits closely with the magnesium metal frame to achieve the balance of all elements.
The 2.05kg Precision 5560 is also significantly lower in size than its peers, with only 344mm×230mm×17mm, and if it were not for the highest configuration of the prototype, the starting weight would only be 1.84kg. Mobile workstations are more durable and stable than mainstream commercial notebooks, and in such scenarios, the use of mainstream configurations, especially centralized configuration workstations, can better ensure the reliability of the system.
The high-end model, specifically, is equipped with a 4K 100% AdobeRGB touch screen, 32GB×2 DDR4-3200 memory, 2TB PCI-E 4.0 SSD, 86Wh battery, and more equipped with NVIDIA RTX A2000 4GB GDDR6 professional graphics card prototype positioning, more suitable for professionals working around visual creativity. At the same time, the Precision 5560 also offers another unique display option, the Quadra T1200 4GB GDDR6, which is mainly aimed at computing acceleration applications such as IA. Users can choose according to the computing power requirements of their own applications on the GPU. In general, the PRECISION 5560 CPU and GPU are very flexible, with both 6 or 8 core Core/Xeon, and two versions of UHD core and two versions of NVIDIA professional unique display, fully meeting the needs of professional configuration.
The specific SPECviewperf test results are shown in the figure above. If you have to use this performance performance requirements Precision 5560 will inevitably be biased, after all, its CPU + GPU performance release level is limited to 45W + 45W level, picture quality and running quality (fluency) to be guaranteed first.
Also guaranteed to the greatest extent is the quality of the product's workmanship, which is closely related to the durability of the whole machine, especially the durability used during frequent movements.
Compared with the more tough carbon fiber needs to be combined with the magnesium alloy frame to bring enough rigidity to the fuselage, the top cover and bottom shell of the Precision 5560 are made of aluminum alloy CNC molding, the thickness is increased, the shape is three-dimensional, and it has good rigidity. The three layers have the effect of bearing pressure and anti-twisting, and the ability of the whole machine to resist external force damage is more balanced.
At the same time, in order to provide better protection for the interface and disperse stress in the event of physical damage, Precision 5560 edge protection can be described as sparing no effort. As can be seen in the figure above, not only is the shell of the CNC thicker than the conventional process, but also the aluminum alloy number is larger and harder, at the same time, the only analog interface on the fuselage - the 3.5mm headphone interface, the connector is fixed to the shell, through the reed and the PCB (blue) of the integrated relatively low-speed SD card reader, and then connected to the main PCB through the flexible FPC, the FPC has no increase in metal protection, effectively shielded from interference, and the mechanical force of the insertion and removal equipment is also fully absorbed and will not be transmitted to the motherboard Metal sponge EMI protection and metal reinforcements are standard on every interface.
The protection of the two ultra-high-speed Thunderbolt4 interfaces is more "excessive", not only the JHL8040R transponder chip adds a shielding cover and an embedded thermal conductive adhesive pad, but also the outer side of the shielding cover also adds a two-layer thermal diffusion reinforcing structure of graphite and copper foil; the underside of the metal reinforcement of the corresponding interface adds a black coating with both insulation and enhanced thermal radiation.
The Precision 5560 uses a workstation-specific WM590 chipset that provides two SSD slots in addition to the PCI-E 4.0 interface used by the GPU and Thunderbolt 4. The machine continues the "excessive" thermal protection on the chipset, adding a separate heatsink to it.
If it is a pity that the WWAN module cannot be installed, the focus on enhancing Wi-Fi performance is Dell's compensation for the Precision 5560. The all-over metal material is very unfriendly to wireless signal penetration, and the antenna is arranged under the touchpad or on the inside of the screen, which is also difficult to ensure signal quality and stability.
Precision 5560 onboard AX201 Wi-Fi 6 module, two dual-band antennas are placed on either side of the fuselage, each antenna is tightly fixed to the magnesium alloy frame by 3 screws, metal sponge enhances EMI protection, and the radiant opening on the bottom case, the same shape as the downward subwoofer opening, is discreet, aesthetically pleasing and larger than other solutions.
In a sense, the Precision 5560 is a compromise, or so to speak, an eclectic product. It has the portability of the Latitude 9520, while having the performance, quality, reliability and durability of the workstation, it can provide professional users with better mobility capabilities, to put it bluntly, it is to sacrifice performance for portability, but never sacrifice quality (running quality, output quality, hardware quality). If it is not to adapt to such requirements, Precision 5560 can be lighter and thinner, but that quality, worthy of "Precision"!
Precision 7560：
The main force, the performance
After watching the "Emperor Uncle" Latitude 9520 full of wisdom and high sense, the "Martial Saint" Precision 5560 with both strength and detail, it is the turn of the thick and thin strength player "Yanren" Precision 7560.
Under the name "7", the Performance Level of the Precision 7560 is evident, with an optional overclockable processor and 110W-class GPU. Of course, as a professional user for high performance needs, the Precision 7560 is more flexible in configuration, and it is not an exaggeration to say that it can even be compared to desktop computers, while it is also more portable/mobile.
The Precision 7560, shown in the official picture, is equipped with a non-touch screen, while the test prototype goes a step further, equipped with a touchscreen with a resolution of 1920 × 1080. Yes, the Precision 7560 and Precision 5560 are both 15.6 inches, but the screen ratio is different, slightly different in the LEVEL of ISV software adaptation, the former is more "traditional". The performance of the Precision 7560 includes calculations, graphics, and images in a variety of different dimensions. Purely reflected in the screen level, including Full HD and QHD resolution, touch and non-touch, 45% NTSC/100% DCI-P3/100% AdobeRGB, HDR, brightness and other options, users can choose different specifications according to their software needs.
Compared with the latitude 9520 and Precision 5560, which can be seen at a glance, the thick Precision 7560 space management is very "extensive", the same screen diagonal size, its body size reaches 360mm×242mm×34mm, and the medium prototype weight is also 2.54kg. Because of this, the Precision 7560 can provide users with more configuration, functionality and performance features that are not possible with thin and light mobile workstation products. Proximity sensing + infrared facial recognition systems have become standard on Dell's high-end models, and the Precision 7560 adds a physical shield.
Performance is the core factor that users must choose 7 Series Precision. Equipped with 8 cores, Turbo 5GHz, open overclocking Core i9-11980HK processor, RTX 3080 16GB GDDR6 unique display, 32GB×2 DDR4-3200 memory, is already the existence of the top game book, and this is only the medium level of high-performance mobile workstations.
Precision 7560's cooling system, the shape is too low-key, placed in the world of the gamebook, will inevitably attract countless complaints. However, the stability and guarantee of performance does not look at the shape to see the efficacy. The machine can provide stable CPU and GPU cooling capabilities, and the ambient temperature is as high as 27 °C, but it can still maintain a total of 150W performance output of both. Its full-core Turbo Boost speed is stable to 4.5GHz nominal and stable at 4.1GHz. Although the TDP set by precision 7560 is still 2.6GHz@45W rather than 3.3GHz@65W, the machine is appropriately open to overclocking capabilities, in addition to the CPU, it also provides 5% amplitude overclocking for ordinary memory, which is also a potential reason for its overall performance.
Graphic graphics, not the only thing the Precision 7560 excels at, is very versatile in its optional GPU models, including two versions of the core display (corresponding to Core and Xeon), GeForce full series and Quadro full range. As a general-purpose mobile workstation, the test results of SPECworkstation are more referenced, and the test results of 3.0.2 and 3.1.0 are taken as required.
It should be noted that because the prototype is equipped with GeForce instead of Quadro, some of the test projects that require corresponding professional graphics features cannot be completed, and users with corresponding application needs, please choose the appropriate version of the GPU, the difference of $, it is not discussed here.
In addition, GPU Compute can choose different acceleration modes, CPU, OpenCL, CUDA and other different modes, the above data is completed by CUDA, and other acceleration instruction scores cannot be synchronized.
In terms of the configuration of the prototype, it is not limited to computing acceleration, but also has the display and acceleration capabilities of graphics workstations. SPECviewperf's results are also available to everyone.
Performance is the key indicator affecting the production efficiency of a total workstation, and optimizing performance is the key to examining the product strength of manufacturers. Today, Dell Optimizer has penetrated latitude to Precision's high-end commercial product line, and the same software has different functions in the two series.
In addition to basic optimization of up to 5 application software performance, power, network, and proximity sensors, Dell Optimizer on Precision features a unique performance analysis module that provides comprehensive analysis of workflow, system performance, and system failures, making it easy for IT staff to adjust the appropriate hardware, software, and equipment parameter configurations, and even assigning more reasonable workflows and workloads to different machines to maximize performance from stand-alone to clustered.
Unlike the GPU performance analysis provided by NVIDIA, dell Optimizer's performance analysis is for the whole machine, rather than a separate function module of the GPU. The two can be used together to provide complete recommendations from the underlying hardware configuration to driver optimization for the user's specific application (version).
In addition to the larger 17-inch Precision 7760, the Precision 7560 has the strongest hardware scalability in the entire series, playing the limits of Intel's hardware platform, which is also the tradition of Dell workstation products. 4 memory slots for a maximum capacity of 128GB for a PC platform limit. Two empty (fang) empty (bian) slots such as (kuo) also (zhan) are located at the bottom of the Precision 7560, which can be reached by removing the bottom case; the two that are preferred are located under the keyboard, covering the shell integrated with the keyboard liner, and have both functions such as support, EMI shielding, and waterproofing.
With a total of up to 5 PCI-E slots for expansion capabilities, who wouldn't want that? In particular, it also includes three PCI-E 4.0 x4 M.2 2280 slots for high-performance SSDs, which are very flexible for future expansion and direct array composition.
In addition to the SSD, the Precision 7560's WLAN and WWAN modules (eSIM or built-in NanoSIM card slots) are standard and replaceable, making it easy to upgrade at any time during the entire life cycle. The Precision 7560 is very forward-looking equipped with a 3-band Wi-Fi antenna, hidden on the outside of the fans on both sides of the fuselage, not affected by fan heat dissipation and aluminum alloy housing shielding, and better signal quality can be obtained with larger spacing. The prototype is equipped with the AX210's Wi-Fi 6E module and is already available for state-of-the-art technology.
To ensure continuity of work, migrating data to another system is the fastest way to move data to another system when a computer hardware platform is damaged, and retaining a hard drive for repairs is also a basic value-added service. For the compact M.2 spec SSD, the bracket became a very rare piece of equipment, but the Precision 7560 retained. The Quick Access Door backshell is an option for the Precision 7560, which costs only $36, allowing you to quickly disassemble the main SSD without removing the bottom case.
It should be noted that this function is not for physical anti-theft purposes, nor does it have hot-swap features, and if necessary, it is necessary to use a cone.
Precision 7560 features comprehensive and traditional features two Thunderbolt4/USB4 ports, an SD card slot, two USB-A 3.2Gen1 (5Gb/s) ports, a SmartCard slot, a MiniDP 1.4 interface, an HDMI 2.1 interface, and an RJ45 Gigabit Ethernet interface.
A synthetic touchpad with 3 independent physical keys, a keyboard with full-size keys even in the numeric keypad area, an optional FIPS fingerprint reader on the right palm rest, and a dark skin-like coating on the palm rest are also not "trendy", but for professional users who have no time to pay attention to hardware differences and focus on their work, this is the most continuous and more reliable + convenient design.
Not as pretty and less trendy, but the Precision 7560 is the work partner you can trust.
Brothers work together, and their profits are broken
From the Latitude 9520, Precision 5560 to precision 7560, Dell uses three high-end models with clear positioning, covering different user requirements for large size, performance, portability and scalability. They are irreplaceable and interconnected in the Dell business notebook sequence.
Although the fineness of latitude 9520, the ruggedness of Precision 5560 and the ruggedness of Precision 7560 vary in appearance and function, product quality, design philosophy and spirit (proprietary software) have been integrated throughout the series and have become one of their intrinsic links.
Even if the user's role changes in their own business chain, whether it is a project manager, a product manager or an engineer, they can find the one that suits their current role.
With a rich product portfolio, diverse specifications, highly flexible configurations, and consistent quality and service, users can face only one Dell and make it easier and more accurate to find the choice that meets their needs.
Again, the "high-end" of high-end commercial models is not how high the CPU, memory, storage, GPU, screen configuration or performance are, these can be directly exchanged for budget. The high level of the high-end model is how close it is to the customer's demand, and it requires manufacturers to have a product customization system around the user. To put it bluntly, it is that the product is close to the user's needs and changes with the user's needs, which is neither comprehensive, allowing consumers to choose the required characteristics from them, nor pulling consumers together to compromise on costs.
In addition to the "standard" models such as Latitude or Precision, based on good parts, workmanship and design, with slight changes and enhancements, Dell's business notebook product line further extends the Rugged (rugged) series of products, as well as more customized models and usage scenarios, their genes are hidden in the standard products.
