Recently, I want to assemble a pure white sea view room host,It already has a white back-plugged motherboard、Chassis and water cooling radiator,There is still a lack of a white style independent graphics card,At present, there are still two major manufacturers on the marketNVIDIA and AMD,The game performance of a card at the same price is higher,Especially the memory capacity parameters are relatively better,It is not easy to explode the video memory on the high-resolution screen,At the same time, considering the performance and budget and other reasons,I specially purchased a sapphire RX 6750 GRE 12GB polar version of the graphics card, which adopts a pure white design, as a dessert graphics card at the early 2K price point, the game performance at 2K resolution does give people a lot of surprises, which fills the gap between RX7600 and RX 7700XT, and then test its performance and heat dissipation to see how strong it is.
The Sapphire RX 6750 GRE 12GB Polar Edition graphics card adopts a pure white exterior design, the front air shield is made of hard plastic, and there are line textures on the surface as embellishments, which are quite unpretentious and have no fancy design elements in the overall appearance, giving people a simple and elegant visual experience, and the upper and lower sides of the front are beveled wedge-shaped design, with sharp edges and corners, and the shape is tough and three-dimensional.
The graphics card is equipped with two cooling fans, located in the middle of the fan blades with a sapphire logo decoration, the cooling fan adopts a framed fan blade structure design with dual ball bearings, so that it has good low noise performance and durability, and the fan also supports intelligent start-stop technology, which will stop rotating and passively dissipate heat in a low-power state such as standby, effectively reducing operating noise.
Sapphire RX 6750 GRE 12GB Polar Edition graphics card is equipped with PCIe4.0×16 specification interface, and is made of high-temperature resistant 10-layer high-quality PCB, which can withstand higher load conditions and further enhance performance stability.
Sapphire RX 6750 GRE 12GB Polar Edition graphics card is equipped with 8+6Pin external power supply interface, located at the top of the rear position, the chip manufacturer nominal typical board power is 230W, the overall power consumption is not very high, the recommended minimum power supply is 650W, if it is matched with a high-end performance processor, you need to upgrade the power supply to fully meet the power supply needs of the entire hardware platform.
The graphics card is equipped with a one-piece full-size metal backplate, covering this PCB board, and there are some brand logos and hollow designs on the surface of the backplate in order to take into account the heat dissipation effect and decoration, and the graphics card adopts a standard double-slot thickness design, with a size of 260×120×49mm, a relatively short and thin body design, so that its installation compatibility in a small chassis is very good.
Through the hollow grille on the upper and lower sides of the graphics card and the rear side, you can see the internal heat dissipation fins and heat pipes, the aluminum heat dissipation fins are designed with a horizontal layout and are very dense, equipped with a total of four nickel-plated heat pipes, as can be seen from the figure, there are five heat pipes extending from the GPU core to the heat dissipation fins, two of which are a whole, which can dissipate heat for the GPU core, video memory and power supply components, forming an air duct from the left and right sides of the front cooling fan to the inner air inlet.
Sapphire RX 6750 GRE 12GB Polar Edition graphics card is equipped with three DisplayPort1.4a video output interfaces, as well as an HDMI2.1 video output interface, all interfaces support 4K120Hz and can also support 8K60Hz picture output, and support VRR (variable refresh rate) and other technologies, which can realize multi-screen output display, which is completely enough for multi-screen parties.
Due to the need for post-warranty services, this time I will not disassemble this graphics card, this assembly is a pure white sea view room style host, sapphire RX 6750 GRE 12GB polar version of the graphics card design, and the overall color of the host is specially matched, because the graphics card itself has a certain weight, in practice, with the graphics card bracket to make the graphics card more reasonable.
Another major feature of this host is the use of a back-pluggin motherboard, the motherboard will be the processor motherboard power supply interface and most of the data and signal interfaces are designed on the back, while covering the aluminum alloy cover, covering up the original interface solder joints, in the visual appearance is very clean and tidy, of course, the black graphics card power supply cable is still quite eye-catching, and it will be optimized next.
First of all, let's talk about the test configuration,This time I choose the 14th generation Core 14th generation i7-14700K processor from Intel,The main thing is that there is only this processor in hand,If you don't have such high requirements for the processor in the face of general game scenes,Generallyi5 or Ryzen 7 level can fully play the performance of the graphics card,As for the hardware configuration such as the memory module power supply chassis is very conventional。
In terms of the specifications of the Sapphire RX 6750 GRE 12GB Polar Edition graphics card, the GPU core uses the Navi 22 core of the RDNA2 architecture, TSMC 7nm process technology, 2560 stream processors, the base frequency is 2439MHz, the Boost frequency is 2581MHz, and it is equipped with 12GB capacity GDDR6 video memory, the video memory rate can reach 18Gbps, 192bit width, and 384GB/s video memory bandwidth.
The driver of this test is the latest version 24.3.1 driver version, first of all, the benchmark performance test link, the 3DMark benchmark software in the Time Spy project graphics score of 12686 points, Time Spy Extreme project graphics score of 5850 points, Fire Strike Ultra project graphics score of 8316 points, Time Spy graphics score more than RTX4060 graphics card.
The graphics card supports real-time ray tracing effects, and also supports ray tracing effects in many of the most recent triple-A games, and then tested the graphics card's ray tracing performance, the graphics card scored 2245 points in the Speed Way project, 6350 points in the Port Royal project, and 50523 points in the Solar Bay project in the 3DMark benchmark software.
The graphics card supports AMD FidelityFX Super Resolution (FSR) display technology, AMD released FidelityFX Super Resolution (FSR) version 3.1 at the Game Developers Conference (GDC), which improves image quality and reduces screen flicker, and has FSR2 functional testing in 3DMark benchmark software, covering quality, balance, Performance and ultra-high performance are four different gears, and the performance differences between off and different gears are 82.8%, 116.9%, 165.3%, and 293% respectively under the 2K resolution screen setting, and the improvement of FSR2 frame rate is still very obvious in the theoretical test.
The score of the game depends on the performance of the actual game, enter the actual game test link, all the following game tests are carried out at 2K (2560×1440) resolution, the racing masterpiece "Forza Horizon 5", using the game's built-in benchmark test function, select the preset extreme screen settings, turn on the TAA anti-aliasing effect, turn off FSR, and the measured average frame rate is 89FPS.
Horizon 5 This game is very much video memory,Thanks to the blessing of 12GB large capacity video memory,You can easily turn on the highest image quality setting,If it is 8GB video memory, it is easy to appear insufficient video memory prompts and affect the smoothness of the picture,In the game "Cyberpunk 2077" choose the preset super image quality gear,Manually turn off FSR and ray tracing effects,The average frame rate of the measured benchmark is 53.36 FPS。
Although the super image quality setting does not reach the smooth line of 60FPS,But you can increase the frame rate through the FSR function,The game itself supports FSR,Test the frame rate of four different gears respectively,The frame rate in the quality and balance file is increased to 69.55 and 83.06FPS respectively,Personally, it is not recommended to choose performance and super performance files,The picture clarity will be significantly reduced after opening,It is not as practical as reducing the image quality file。
In terms of ray tracing effect,The game has four built-in different levels of ray tracing,They are low、Medium、Super and overspeed preset gears,Benchmark tests respectively,The picture parameters are all preset and have not been modified,Low and medium frame rates are 70.35FPS and 43.41FPS respectively,You can try to play,Due to the extreme consumption of hardware resources in the overdrive picture mode,The game frame rate can only reach 15.28FPS,This is still open in FSR mode,The frame rate is estimated to be only single digits。
The large-scale game "Shadow of the Tomb Raider: Shadows", this time choose to preset the highest image quality level, using the game's built-in benchmark test, the average frame rate of the Sapphire RX 6750 GRE 12GB Polar Edition graphics card is measured to be 110FPS, the game can turn on the ray tracing effect, if the full image quality options are full, the average frame rate is reduced to 66FPS, ray tracing has great pressure on the GPU computing power.
In the game Red Dead Redemption 2, select 2K resolution, manually adjust the image quality setting to the maximum, DX12 graphics API mode, no other graphics items are modified, using the built-in performance benchmark function, the average frame rate of the measured graphics card is 78.9FPS, which can achieve smooth gameplay above 60FPS throughout the whole process.
Watch Dogs: Legion from Ubisoft, in the game is set to DX12 graphics API mode, and the preset maximum image quality is selected, and the ray tracing effect is turned off by default, as can be seen from the built-in benchmark test results, the average frame rate is 71FPS, and the 1% low frame is 59FPS, at this time, the video memory occupies 9GB, which can get a smooth game experience with a stable 60FPS or more.
For "Genshin Impact", the game is no longer satisfied with the 60Hz picture refresh rate, after all, it has now entered the era of high brush screen, using tools to unlock the 60Hz refresh rate limit, and fill up the various picture parameters, turn on 1.5 times the rendering accuracy and extremely high scene detail, and fill up the GPU graphics performance, Sapphire RX 6750 GRE 12GB Polar Edition graphics card can stabilize the frame rate in this game at 90FPS.
Recently landed on the PC platform of the game "Horizon: Forbidden West", in 2K resolution preset to the highest image quality setting, turn off the FSR effect, the measured game frame rate can reach 64FPS, because the game is an open map, so it consumes video memory very much, in some scenarios the video memory occupies up to 10GB, and the graphics card is equipped with 12GB of large video memory advantages are reflected.
In the "Elden Ring" game, choose the preset highest quality mode, turn off the ray tracing effect, the measured game can stabilize 60FPS, the performance is not yet full, although you can unlock 60 frames but I don't think it's necessary, the large DLC expansion "The Shadow of the Golden Tree", will be officially launched at the end of June, Sapphire RX 6750 GRE 12GB Polar Edition graphics card can ensure that the frame rate is stable at 60FPS.
In the game "Monster Hunter World: Iceborne", select the preset highest image quality, and enable the 4K HD texture pack, because anti-aliasing will cause the picture to become blurry, so manually turn off the anti-aliasing effect, and other image quality parameters are not modified, when hunting steel dragons in the wild, the measured game frame rate is 73FPS.
That's all for the stand-alone game performance test,Next is the online game test,The game frame rate may be affected by the network or optimization,The actual results are for reference only,First of all, the battle game "DOTA2", choose the highest image quality of the preset, the frame rate is basically in a full frame state when you wander around the jungle in the wild, and when you encounter a large-scale team battle in the late game, the frame rate will drop to about 144FPS when various skills are released at the same time.
Different types of games have different requirements for frame rates, for shooting competitive games, in fact, they don't care much about the picture effects, players pay more attention to the number of frames, generally speaking, the higher the frame rate, the smoother, 60FPS is only the passing line, in the "CS2" competitive game, choose a preset very high image quality setting, the game frame rate is basically around 154FPS.
The classic chicken game "PUBG", preset ultra-high image quality settings, the game scene is the Erangel map, the game frame rate is basically hovering at 106FPS, there is no problem at all to meet the needs of absolutely smooth games, if there are higher fluency requirements, you can use the three extremes and other all-low picture settings, the frame rate will be increased to about 190FPS, and the high-brush monitor can bring a silky game experience.
I have tested a lot of games,I believe you already know the approximate performance level of this graphics card,Game performance test is here,Next, stress test the graphics card,Look at the actual heat dissipation efficiency and operating noise performance of the graphics card,The indoor temperature is about 28°C during the test,First use FurMark2.2 version to test its bake,The software shows that the power consumption is 183W when fully loaded,For a graphics card equipped with four heat pipes and dual cooling fans,The heat dissipation pressure is not particularly high。
The GPU-Z detection software is used to export the temperature and power consumption of the graphics card, and the continuous baking time is about 40 minutes, and the system controls the fan speed by itself, the measured power consumption of the GPU core when the oven is fully loaded, and the temperature is always maintained at about 72°C, while the HotSpot temperature is 83°C, the fan speed is maintained at 1900rpm, and the fan speed percentage is about 60%.
The Sapphire RX 6750 GRE 12GB Polar Edition graphics card has a very good power consumption and temperature control, of course, if you manually adjust the fan speed in the control panel, you can further reduce the core temperature, and the 3DMark benchmark software is used to perform a 30-cycle stress rendering test on the graphics card, showing a frame rate stability rate of 99.4%, and the performance release is smooth and durable.
The following test results are for reference only, because the physique of different cores is different, the degree of overclocking and parameters may not be applicable to all, the graphics card overclocking can be operated in the AMD graphics card control software, this time the maximum frequency of the core will be increased to 2700MHz, and then it will be unstable, the video memory frequency will be increased to 2050MHz, the voltage value and power value will be full, and the fan will select automatic mode.
After overclocking, you need to use 3DMark or the game to stress test whether it is stable, using 3DMark's Time Spy project to benchmark the performance test, the graphics card score before overclocking is 12686 points, and the score after overclocking is 13412 points, and the running score score is only improved by 5.72%.
In the benchmark test of "Cyberpunk 2077", the frame rate has increased by about 2FPS compared to the silent frequency, and the frame rate in "Forza Horizon 5" has increased by 4FPS, and the core temperature has not changed too significantly.
General Comments:
The Sapphire RX 6750 GRE 12GB Polar Edition graphics card adopts an angular design, with oblique cutting decorations on the upper and lower sides of the front, making it a little three-dimensional. The air deflector and the metal backplate are pure white, low-key and unassuming in terms of details, and there is no fancy or lighting design, giving people a simple and elegant look, which is very consistent with the white sea view room style host, which adopts a dual-fan dual-slot structure design, which is significantly better for the compatibility of small-volume chassis, and is not afraid of causing obvious weight pressure on the motherboard interface.
In terms of performance, it meets the performance of the price, with 12GB capacity and 192bit wide video memory, you can easily grasp 2K resolution picture games, as long as you don't actively turn on the ray tracing effect, most games can easily achieve a full frame 60 frames output at a high image quality setting value, some games can reach more than 100 frames, the full load power consumption of the graphics card is not high, the built-in four nickel-plated heat pipes supplemented by a dual fan cooling system are enough to easily deal with it, it is very well controlled in terms of fan noise, only a slight wind sound is heard when fully loaded, and the temperature and noise are always kept in just the right balance。
