AMD's RX 6750 GRE graphics card has been quite popular lately, but it's still quite dramatic. Although it was released recently, the product itself belongs to the RX 6000 series, but it is known for its outstanding price-performance ratio. Bringing today is a review of the Sapphire RX 6750 GRE 12G D6 Black Diamond Edition.
Regarding the naming of the product, I would like to say more here, "GRE" is not a conventional series of products, the full name is - Golden Rabbit Edition, that is, "Golden Rabbit Edition", so you can see the shape of a rabbit on the outer packaging of the product.
Sapphire RX 6750 GRE has a number of series to choose from, including Aurora Edition (blue), Polar Edition (white), Platinum Edition (red and black), and the Black Diamond Edition (black gold) in our review.
In addition, in addition to the 12GB/192bit video memory version of this test, there is also a 10GB/160bit video memory version (note: the video memory bit width is affected by the change of capacity, 1GB is 16bit), the price difference between the two is about 200 yuan, you must pay attention to it when purchasing.
From the perspective of specification positioning, RX 6750 GRE is roughly between 1080p and 2K, so if you are only a player who plays under 1080p, 10GB video memory is also completely sufficient, saving 200 yuan, performance is not reduced, and it is a proper cost-effective card.
1 Sapphire RX 6750 GRE 12G D6 Black Diamond Edition at a glance
The Sapphire RX 6750 GRE 12G D6 Black Diamond Edition comes in a new package, with a wide range of polished diamonds as embellishments, and a unique black and gold design language in the middle of the Black Diamond Edition, which highlights the "diamond" characteristic of the overall style.
On the right side of the package, there is a small rabbit lying on its stomach with its head facing the upper right corner, which means "Golden Rabbit Version". However, this little rabbit is more abstract, and from the direction, it is easier to confuse it as a duckling.
In terms of size, the Sapphire RX 6750 GRE 12G D6 Black Diamond Edition is 310×128×51mm, taking up 2.5 slots of space, and adopts a three-fan full-size design. The two sides of the graphics card are chamfered, which has some hints of the platinum version.
The front of the graphics card is solid black, with a line texture on the surface, which divides the shroud into different areas, each with a dark grid of diamond triangles, supplemented by irregular gold triangles as embellishments. Although there are more elements on the stuck body, the overall feeling is still relatively plain.
The Sapphire RX 6750 GRE 12G D6 Black Diamond Edition uses three 9-blade winged axial fans, which are two large and one small. Dual ball bearing construction for extended fan life.
In the center of the fan is a nameplate sticker with black diamonds, and the four diamond faces on the right side are polished to create a mirror effect by reflecting the light.
The Sapphire RX 6750 GRE 12G D6 Black Diamond Edition features an integrated metal backplate on the back to protect the PCB and enhance heat dissipation.
The overall design of the back panel continues the diamond triangle dark pattern with gold accents on the front shroud, which is also relatively simple but has an outstanding texture.
In terms of internal heat dissipation, 4 nickel-plated heat pipes and thickened fins are used, and the heat pipes running through the end can quickly and evenly divide the heat into the entire heat dissipation module.
In addition, this graphics card uses a high-density 10-layer PCB board, which can improve the signal transmission speed and signal stability of the graphics card, and has high durability to ensure the performance and stability of the graphics card in long-term operation.
The Sapphire RX 6750 GRE 12G D6 Black Diamond Edition has a thickness of about 2.5 slots, and you can see from the side that the fan part is quite prominent. The video output interface adopts the design of HDMI 2.1*1+DP 1.4*3. Although the RX 6000 series still uses the DP1.4 design, it is more than adequate for now.
In terms of external power supply, the Sapphire RX 6750 GRE 12G D6 Black Diamond Edition uses an 8+6pin interface, which is the same as other RX 6750 GRE series products, and the recommended power supply is 650W.
2 Introduction to the test platform
The test platform selects the current flagship processor, and the memory is D5 standard specification 32GB 6000MHz. In addition, we have updated the system to the latest 22H2 major version, and it is recommended that players who are mainly engaged in the game also upgrade to the WIN11 system. AT PRESENT, MICROSOFT HAS ABANDONED THE WIN10 UPDATE, AND MOST GAME MANUFACTURERS AND HARDWARE MANUFACTURERS HAVE BEGUN TO OPTIMIZE FOR WIN11.
The GPUZ is quite comprehensive for the RX 6750 GRE, and it is worth noting that the RX 6750 XT and RX 6750 GRE are both 2560 stream processors, and the raster/texture units are also the same, 64/160.
In terms of video memory, the RX 6750 GRE has 12G GDDR6 memory and a bit width of 192 bits, but the memory frequency is slightly lower than that of the RX 6750 XT, so the overall bandwidth is 384 GB/s.
3 Theoretical performance test
THE FOLLOWING IS THE 3DMARKFS PACKAGE USED TO MEASURE THE THEORETICAL PERFORMANCE OF THE GRAPHICS CARD DX11: FS, FSE, AND FSU CORRESPOND TO THE THEORETICAL PERFORMANCE OF THE GRAPHICS CARD AT 1080P, 2K, AND 4K RESPECTIVELY, AND THE ACTUAL TEST RESULTS OF THE GRAPHICS CARD SCORE ARE AS FOLLOWS:
In this test, we chose the RTX 4060 and the Sapphire RX 6750 GRE 12G D6 Black Diamond Edition for comparison.
IN THE 3DMARKFS SUITE TEST FOR GRAPHICS CARD DX11 PERFORMANCE, THE SAPPHIRE RX 6750 GRE 12G D6 BLACK DIAMOND VERSION IMPROVED FS BY 26%/FSE 34%/FSU 48% COMPARED TO THE RTX 4060, WITH AN OVERALL INCREASE OF 36%.
In the Time Spy and Time Spy Extreme tests for DX12 environments, the Sapphire RX 6750 GRE 12G D6 Black Diamond Edition improved by 19% in TS, 16% in FSE, and 18% overall compared to RTX 4060.
PortRoyal is a 3DMec test item dedicated to ray tracing performance, and the Sapphire RX 6750 GRE 12G D6 Black Diamond Edition is about a 4% improvement over the RTX 4060.
The Speed Way test is the latest update of 3DMARK to test the performance of DirectX12 Ultimate. Testing uses a combination of real-time ray tracing and traditional rendering techniques to measure graphics performance. Scenes include ray-traced reflections, real-time global illumination, mesh shaders, volumetric lighting, particles, and post-processing effects.
It can be seen that at high resolution, the Sapphire RX 6750 GRE 12G D6 Black Diamond Edition gradually closes the gap, of which 12GB of video memory plays a big role, which is also reflected in later game tests.
IN 3DMARK'S FSR TEST, THE SAPPHIRE RX 6750 GRE 12G D6 BLACK DIAMOND VERSION ACHIEVED A 74%/83%/101% PERFORMANCE IMPROVEMENT IN ALL THREE RESOLUTIONS. The higher the resolution, the more obvious the improvement effect after turning on FSR, and the better the image quality is maintained.
Overall, the Sapphire RX 6750 GRE 12G D6 Black Diamond Edition significantly outperforms the RTX 4060 in both DX11 and the underlying DX12 environment, and remains ahead of the curve in ray tracing.
However, in SpeedWay's next-generation comprehensive test, the RX 6750 GRE still has a gap with the RTX 4060 when the disadvantages are added up.
4 Game Performance Testing
IN TERMS OF GAMING TESTING, THE PERFORMANCE REFLECTION IS NOT AS ACCURATE AS 3DMARK'S THEORETICAL SCORE BECAUSE A/N INVOLVES OPTIMIZATION BY DIFFERENT COMPANIES, BUT WE HAVE ALSO TESTED A FEW MORE POPULAR TRIPLE-A GAMES.
As a traditional project of graphics card testing "Assassin's Creed", this time it was updated to the latest version of "Assassin's Creed: Mirage", compared to the previous "Valhalla", "Mirage" is a little more configured, but the score difference is no more than 5 frames, in general, since "Valhalla", the Assassin's Creed series optimization, which claims to be equal to all beings, has finally gotten better, and it can stabilize 60 frames even at 4K resolution.
In Assassin's Creed: Valhalla, the Sapphire RX 6750 GRE 12G D6 Black Diamond Edition is 5%/10%/2% higher than the RTX 4060, with a combined increase of around 5%.
In this game, the advantages of 12GB large video memory are more obvious in 2K resolution, while in 4K resolution, it mainly depends on the performance of the graphics card, and the advantages brought by video memory are not obvious.
In Forza Horizon 5, the game supports both FSR and DLSS, so in testing, we'll turn on this feature on the corresponding graphics card.
The Sapphire RX 6750 GRE 12G D6 Black Diamond Edition is 1%/15%/35% higher than the RTX 4060 in three resolutions, with a 17% overall increase.
Because Forza Horizon 5 is very well optimized, it does not require high graphics card performance, so at 4K high resolution, it can take advantage of large video memory.
In Borderlands 3, we tested the same DX 12 environment, and the Sapphire RX 6750 GRE 12G D6 Black Diamond Edition was 38%/41%/69% higher than the RTX 4060, respectively, with a comprehensive increase of about 50%.
In Cyberpunk 2077, we divided the test into two parts: Super Image Quality and Ray Tracing Super Quality, with DLSS quality mode enabled for NVIDIA graphics cards and FSR quality mode enabled for AMD graphics cards.
Compared with the RTX 4060, the Sapphire RX 6750 GRE 12G D6 Black Diamond Edition has increased by 8%/16%/10% respectively, and the overall increase is about 11%.
In ray tracing super image quality, the RTX 4060, which is better at ray tracing, has a significant lead at 1080p resolution, but the Sapphire RX 6750 GRE 12G D6 Black Diamond Edition is 33% different from 1080p and 26% to 4K, and the gap is gradually narrowing, which also proves that the advantage of large display at high resolution is very large.
In the Starfield test, we went from FSR to performance, and each gear recorded the frame rate in the most stuck place in New Asia City.
In addition, in terms of FSR gears, Starfield does not have a direct mode selection, but needs to manually adjust the zoom magnification, and we all test it according to the standard FSR quality (1.5x), FSR balance (1.7x), and FSR performance (2x). However, there are no tuning options below 50% in the game, so the 33% super performance ratio is not tested.
Starfield's poor optimization is well-known among recent triple-A titles, but in the latest 1.8.88 major update, the performance and stability have been optimized, and the frame rate has been improved to a certain extent.
The Sapphire RX 6750 GRE 12G D6 Black Diamond Edition can achieve a smooth standard of nearly 70 frames per second with FSR balanced mode on at 1080p resolution, and a smooth gaming experience of around 60 frames at 2K resolution.
However, our tests were all in the most stuck, and if you're in space or on some planets with less populated buildings, you won't have any problems smoothing at 2K.
Although Diablo 4 is an online game, it has relatively high requirements for configuration. Compared with the RTX 4060, the Sapphire RX 6750 GRE 12G D6 Black Diamond Edition has increased by 35%/44%/37% respectively, and the overall increase is about 39%.
We also tested frame rates across all FSR settings, and at 4K, the Sapphire RX 6750 GRE 12G D6 Black Diamond still delivers a very smooth experience.
5 FSR 2 test
In the current version of Diablo 4, the option of FSR 2 has been added (previously FSR 1.0), and we have also tested and compared the effects for different gears, among which the super performance gear has increased by 122% compared to FSR, let's take a look at the picture comparison.
Due to the good optimization of Diablo 4, we chose an indoor environment with a more complex scene and tested the 4K resolution (the frame rate is different from the frame rate test above).
The Sapphire RX 6750 GRE 12G D6 Black Diamond Edition is 59 fps with FSR turned off and 131 fps with Super Performance turned on. These 4 gears are increased to 41%/54%/85%/122% respectively.
In Diablo 4, the more characteristic thing is that the ground texture is very realistic, although it is a top-down view game, but brick by brick, and even the wooden texture of the floor can be clearly presented.
It can be seen that in the original picture of FSR off, the texture of the floor and the masonry of the fireplace are clearly visible. In both FSR quality mode and balanced mode, this feature is well restored.
In FSR Performance mode and Super Performance mode, the edges of the item become blurry due to light interference.
6 Temperature and power consumption test
In the power consumption and temperature test, we chose FurMark software for the copy test, and used GPU-Z to detect the temperature, and the power consumption was only calculated by the graphics card itself.
GPUZ's support for A cards is not complete, Sapphire RX 6750 GRE 12G D6 Black Diamond Edition is down when the graphics card is fully loaded, the oven temperature is around 71°C, the hot spot temperature is 87°C, and the fan speed is 33%, only about 1100 RPM, which is still relatively low. If you want a lower temperature, you can manually adjust the balance between the fan and the temperature.
In terms of power consumption, the GPU power consumption of the Sapphire RX 6750 GRE 12G D6 Black Diamond Edition is 186W, which is 45W lower than the 230W of the RX 6750 XT, which is still quite good.
In the copy machine test, the overall situation of the black diamond version and the platinum version and polar version tested earlier is basically the same, so if you buy it, just choose what you like, there is not much difference in essence.
7 2400 yuan 2K game card
We've tested a number of RX 6750 GRE models so far, so we won't go into detail about the convenience of performance. It basically straddles between RTX 4060 and RTX 4060 Ti, but the current price is only 2449 yuan, which belongs to the entry price to buy mid-range performance.
And although it is a graphics card for positioning 1080p-2K resolution games, for many indie games or online games with low configuration requirements, there is no problem at all to run at 4K resolution, after all, there is 12GB video memory to support, usually video memory is enough.
So users who are still struggling with whether to buy RX 6000 series graphics cards, in fact, they can buy it boldly with confidence, from the architectural point of view, although the RX 7000 series adopts a new process and dual-core packaging, but it is essentially not much different from the RX 6000 series, and there should be a lot of modules.
The Sapphire RX 6750 GRE series is well suited, including the Aurora Edition (Blue), the Polar Edition (White), the Platinum Edition (Red and Black), and the Black Diamond Edition (Black Gold) for this review. Among them, the Platinum Edition and Polar Edition are dual-fan graphics cards, while the Aurora Edition and Black Diamond Edition are three-fan graphics cards, and players can choose according to their actual usage environment.
In terms of appearance, the black diamond version is somewhat similar to the white gold version, both of which have black as the base and different accent colors. But whether it's red with black or gold with black, it's a classic match, and you can choose according to your preferences.
At present, this sapphire RX 6750 GRE 12G D6 black diamond version has been sold in major e-commerce companies, with a daily price of 2499 yuan, a full discount of 50 yuan, 2449 yuan, and then a superimposed red envelope of 30 yuan, and finally 2419 yuan.
