Hello everyone, I am 100% Dusk, AMD officially released three TDP 65W Zen 4 architecture CPUs at CES 2023, namely AMD Ryzen 5 7600, AMD Ryzen 7 7700, Ryzen 9 7900, I am honored to be invited by AMD again to participate in the first test of these three new CPUs, today we will take a look at how these three TDP lower CPUs actually perform.
Well, without further ado, let's drive.
Introduction to the parameters of the three new CPUs
A brief review of the Zen 4 architecture used in the three CPUs, which adopts a new front-end design, made of TSMC's 5nm process, adopts the CCD+IOD design scheme, of which IOD is a 6nm process, not only the whole CPU is equipped with RDNA2 architecture core graphics, but also greatly optimizes the IF bus.
In addition, the CPU of the Zen 4 architecture will be changed to an LGA package with more pins (the pins are on the motherboard side), which can support DDR5 memory and get more PCIe lanes, and the Ryzen 7000 series CPUs provide 28 PCIe 5.0 lanes.
The above content I have covered in the previous Zen 4 architecture first released 4 CPU evaluation articles, here will not be discussed, then let's take a look at the 3 CPUs released this time:
The AMD Ryzen 9 7900 is a 12-core, 24-thread, base clock frequency 3.7GHz, maximum clock frequency 5.4GHz.
The AMD Ryzen 7 7700 is an 8-core, 16-thread, base clock frequency 3.8GHz, maximum clock frequency 5.3GHz.
The AMD Ryzen™ 5 7900 is a 6-core, 12-thread base clock frequency of 3.8GHz and a maximum clock frequency of 5.1GHz.
The TDP of the three CPUs is 65W, and the MAX Socket Power is 88W, which can be said to be much cooler than the Ryzen CPU at the end of X, and then let's take a look at the actual performance of these three CPUs.
AMD Ryzen 9 7900 & Ryzen 7 7700 & Ryzen 5 7600 performance testing
CPU-Z
To evaluate the CPU, the first place is naturally CPU-Z, let's take a look at the scores of the 3 CPUs.
▲ CPU-Z single-core score, AMD Ryzen 5 7600 scored 713.5, Ryzen 7 7700 scored 729.2, Ryzen 9 760.7.
It can be seen that in terms of single-core performance, the performance difference of the three CPUs is not large, it is worth noting that the single-core of the Ryzen 9 7900 can run 760.77 points, and the TDP is only 65W, and the energy efficiency ratio is very high.
▲CPU-Z multi-core score, AMD Ryzen 5 7600 scored 5688, Ryzen 7 7700 scored 7724.5, and Ryzen 9 7900 scored 10557.5.
▲ Among them, the score of the 12-core and 24-thread Ryzen 9 7900 is 1.86 times that of the 6-core 12-thread Ryzen 5 7600, and 1.35 times that of the 8-core 16-thread Ryzen 7 7700, which shows that the multi-core score is basically proportional to the number of cores.
Cinebench R23
Let's take a look at the Cinebench R23 performance of the three CPUs, a cross-platform test suite for testing the hardware capabilities of computers. It can be used to test Cinema 4D's 3D modeling, animation, motion graphics, and rendering performance on multiple CPU cores. The program is "field-specific and better suited for high-end desktop and workstation platforms." Cinebench is often used to show CPU performance.
▲Cinebench R23 single-core score, AMD Ryzen 5 7600 scored 1818 points, Ryzen 7 7700 scored 1863 points, Ryzen 9 7900 scored 1932.
The single-core performance of the Cinebench R23 of several AMD 65W CPUs also proves the excellent energy efficiency ratio of Zen 4 architecture CPUs.
▲ In terms of the multi-core performance of Cinebench R23, AMD Ryzen 5 7600 scored 13738 points, Ryzen 7 7700 scored 18522 points, and Ryzen 9 7900 scored 24500.
Similarly, the score of the 12-core 24-thread Ryzen 9 7900 is 1.78 times that of the 6-core 12-thread Ryzen 5 7600, and 1.32 times that of the 8-core 16-thread Ryzen 7 7700, which shows that the multi-core score is basically proportional to the number of cores.
3DMark CPU PROFILE
3DMark CPU PROFILE is 3DMark's latest CPU performance testing tool, which has the advantage of testing CPU performance at single-thread, 2-thread, 4-thread, 8-thread, 16-thread, and large-threaded CPU respectively to facilitate comparison between different CPUs. This time, the focus is on single-threaded performance versus full-threaded performance.
▲ In a single thread, AMD Ryzen 5 7600 scored 1018 points, AMD Ryzen 7 7700 scored 1056 points, and AMD Ryzen 9 7900 scored 1070 points.
▲ At full thread, AMD Ryzen 5 7600 scored 6703 points, AMD Ryzen 7 7700 scored 8647 points, and AMD Ryzen 9 7900 scored 10972 points.
Combined with previous CPU-Z and Cinebench R23 tests, we can conclude that the single-core performance of the 3 CPUs is not much different. In terms of all-core performance, the difference in the number of cores of the three CPUs is basically proportional to their all-core performance.
Therefore, we can conclude that if you play a game that places special emphasis on single-core performance and optimization for up to 6 cores and 12-thread CPUs, then the Ryzen 5 7600 may be the most cost-effective option, while if you are installing a computer for multi-threaded productivity, it is recommended to buy as many cores as possible according to your budget.
EXPO overclocking with AIDA64 memory test
With the arrival of Ryzen 7000 series CPU, AMD finally provides EXPO one-key overclocking technology, when using AMD EXPO certified memory, users can open the EXPO function in the motherboard BIOS, the same as XMP function, is to read the frequency and timing parameters in the pre-written memory first, and optimize the details according to the memory overclocking potential of the motherboard and CPU, and then achieve the function of one-key overclocking.
▲For example, in the BIOS of the ASUS ROG motherboard tested this time, you only need to select the corresponding EXPO parameter in Extreme Tweaker's AI intelligent overclocking, and AMD's memory overclocking has finally become extremely easy.
▲The memory used this time is Pallas II. DDR5 memory from Acer Predator, which is specially built for AMD Zen 4 CPU, and its EXPO frequency and timing is 6000MHz CL30-38-38-76, which should be the lowest DDR5 memory in the current timing, and the current annual goods only need 999 yuan to start.
▲ According to AIDA 64 measurements, the Pallas II. DDR5 memory of Acer Predator has a read speed of 74535MB/s at 6000MHz, a write speed of 76715MB/s, a copy speed of 68826MB/s, and a latency of only 68.9ns. This is already similar to the delay of DDR4 memory overclocked to 6000MHz, on the one hand, it can be seen that DDR5 has made significant progress in performance and delay control since its release, on the other hand, it can confirm that AMD's official claim that EXPO technology can currently control the memory delay at 63ns.
▲ Because AMD has officially promoted that the memory performance of the Ryzen 7 processor is 6000MHz, so there will be no more overclocking tests here, and if I have time and opportunity, I will conduct extreme overclocking tests.
7-zip test
The installation package of computer software is actually compressed files, and many files in the game are also in the form of compressed packages, so the performance of computer decompression is very important for both games and offices, let's take a look at the difference between compression and decompression performance of the 3 CPUs.
The AMD Ryzen 5 7600 has a compression score of 85 GIPS, a decompression score of 98 GIPS, and an overall rating of 94 GIPS.
The AMD Ryzen 7 7700 has a compression score of 116 GIPS, a decompression score of 131 GIPS, and an overall rating of 124 GIPS.
The AMD Ryzen 9 7900 has a compression score of 149 GIPS, a decompression score of 183 GIPS, and an overall rating of 166 GIPS.

▲ Ryzen 9 7900 score is 153.6% of Ryzen 5 7600 score.
Shadow of the Tomb Raider
▲ Next, let's take a look at the game performance of "Tomb Raider, Shadow", the game picture quality is 1080P the highest quality, the light chasing is fully open, under this setting, the game puts the most pressure on the CPU.
▲ In the test of "Tomb Raider", the frame rate of Ryzen 5 7600 and Ryzen 7 7700 is basically the same, at 201 (202) FPS, while Ryzen 9 7900 is higher, at 208 FPS.
《F1 22》
▲The annual racing masterpiece "F1 22" supports both ray tracing and FSR technology, and the performance of the three CPUs is also the highest image quality.
▲ I have retested the game results many times, the 8-core 16-thread Ryzen 7 7700 has the highest frame rate of 244FPS, Ryzen 9 7900 frame rate is the second, 239 FPS, even the Ryzen 5 7600 has a high frame rate of 235 FPS.
I do not confirm the reason for this result, so here I will only make an objective statement and not a subjective guess.
Cyberpunk 2077
▲ First of all, the increasingly well-known "Cyberpunk 2077", this game supports both ray tracing technology and FSR technology, let's experience the charm of Night City together.
▲ In "Cyberpunk 2077", the average frame rate of the three CPUs is basically the same, 96 (97) FPS, but we can find that the lowest FPS of the three CPUs in the benchmark is quite different, Ryzen 5 7600 is 57 FPS, and Ryzen 7 7700 and Ryzen 9 7900 are 65FPS and 67FPS, which is basically 10 frames higher than Ryzen 5 7600.
Borderlands 3
▲ The other day the EPIC mall was discounted again, the standard version of "Borderlands 3" only costs 29 yuan, this is an RPG FPS game with built-in Benchmark, this game does not support ray tracing, we still use 1080P resolution, the highest (villain) quality testing.
▲ In the test of "Borderlands 3", Ryzen 5 7600 is 250 FPS, while Ryzen 7 7700 and Ryzen 9 7900 have the same frame rate, which is 254 (255) FPS, which is slightly higher than Ryzen 5 7600.
V-ray Benchmark rendering test
After testing the basic performance and game performance of the CPU, let's test the digital content creation ability of these two CPUs. The software tested is V-Ray Benchmark, where the V-Ray CPU test is used to test the rendering speed of the CPU.
The V-Ray CPU test score of AMD Ryzen 9 7900 is 19152, while the V-Ray CPU test score of AMD Ryzen 7 7700 is 14334, and the V-Ray CPU test score of AMD Ryzen 5 7600 is 10855. The AMD Ryzen 9 7900 score is basically twice that of the AMD Ryzen 5 7600, which coincides with the gap in the number of threads, which shows that the number of threads is the most important factor affecting the CPU rendering speed.
PCMark 10
Finally, we tested with PCMark 10, a comprehensive set of test items covering a wide range of tasks in the modern workplace, a comprehensive PC benchmark for the modern workplace. The test content of its standard version covers three aspects: basic tasks, productivity, and digital content creation.
▲ Let's look directly at the summary chart, in terms of basic tasks (software installation, video, web browsing), the performance of the 3 CPUs is basically the same, around 12000, it can be seen that the Ryzen 5 7600 with 6 cores and 12 Ryzen threads is enough to meet all the performance requirements of the basic tasks of the computer.
In terms of productivity (spreadsheets, writing), the Ryzen 7 7700 scored the highest at 11787, which is slightly higher than the Ryzen 9's 10935, not sure if it is a test error or spreadsheets and writing software that optimizes the 8-core CPU better.
In terms of digital content creation (image editing, rendering and visualization, video editing), the higher the number of cores, the higher the score, especially in image editing and rendering and visualization, the Ryzen 9 7900 scored significantly higher than the other two CPUs.
The total scores of the PC Mark 10 for the last 34 CPUs are 9261, 9637, and 9459.
So, if you're running a computer for the basics, the AMD Ryzen™ 5 7600 is a great place for you. And if you mainly use it for productivity work such as spreadsheets and writing, then choose the AMD Ryzen 7700. If you plan to use this computer for rendering and visualization work or editing photos, then it is necessary to add money to the AMD Ryzen 9 7900.
Thermal testing
Compared with the AMD Ryzen 7000 CPU at the end of X, it is recommended to use water cooling to suppress the difference, and the 3 65W Ryzen 7000 series CPUs evaluated in this review are equipped with air-cooled radiators as standard, which means that its heat dissipation pressure should not be large.
▲ Among them, Ryzen 5 7600 is equipped with a circular air-cooled Ghost Stealth radiator on the left, while Ryzen 7 7700 and Ryzen 9 7900 are equipped with a square Ghost Rush radiator with heat pipes and RGB lighting effects on the right, and I will also conduct the CPU heat dissipation test according to the official standard radiator.
▲Among them, the Ryzen 5 7600 single-baked FPU with circular air-cooled Stealth radiator has a stable temperature of 55°C and a CPU frequency of 4.75GHz for 10 minutes.
▲The Ryzen 7 7700 single-baked FPU with square ghost Prism air-cooled radiator stabilized at 48°C and CPU frequency at 4.9GHz for 10 minutes.
▲The Ryzen 9 7900 single-baked FPU, also equipped with a square Ghost Prism air-cooled radiator, has a stable temperature of 54°C and a CPU frequency of 4.5GHz for 10 minutes.
It can be seen that the heating control of the three CPUs is very good, if not for the cool lighting effect of water cooling, then the use of the air-cooled radiator included in the boxed CPU can easily press these three CPUs, which not only saves the effort of installing water cooling, but also saves money.
summary
This time tested all three new 65W CPUs from AMD:
Ryzen 5 7600, AMD Ryzen 7 7700, Ryzen 9 7900. The pricing is 1549 yuan, 2299 yuan, 3199 yuan respectively, all of which have been pre-sold on JD.com.
In terms of gaming, in fact, the Ryzen 5 7600 already has a good performance, more cost-effective, and can put more budget on the graphics card. And if you want to make the frame rate more stable and enjoy a more silky gaming experience, then it is recommended to choose Ryzen 7 7700 or Ryzen 7 7900.
For everyday applications and productivity tools, the Ryzen 5 7600 can already provide a very smooth experience if it is just for everyday use, while if it is a large number of processing tables and text files, then the Ryzen 7 7700 is recommended. If it is in the area of digital content creation, especially rendering and visualization and image editing, it is highly recommended that you go straight to the Ryzen 9 7900 with more cores.
