Previously, NVIDIA has released a comparison between RTX 3090 and RTX 3080. In terms of game performance, RTX3090 has a 10%-15% improvement over RTX3080. This improvement is not obvious in actual performance, but in a more professional Studio scene, due to more Large video memory can bring more data processing capabilities, so RTX 3090 is more like a computing card in practical applications. In this way, RTX 3090 is more suitable for video creators, artificial intelligence researchers and other groups, and the actual needs of game players RTX 3080 can be well satisfied.
Compared with some previous professional graphics cards, RTX 3090 has launched a non-public version of the product this time. IT House got the non-public version of RTX 3090 graphics card launched by Asus-ASUS TUF-RTX3090-24G-GAMING graphics card (hereinafter referred to as “TUF RTX 3090”), let’s take a look at the performance of the RTX 3090 graphics card in different scenarios through the evaluation experience.
The appearance of TUF RTX 3090 is basically the same as that of TUF RTX 3080. In terms of heat dissipation and power supply, three fans and dual 8-pin designs are selected. The black appearance is more robust than other graphics cards. In terms of heat dissipation, TUF RTX 3090 adopts “full ultra-cold” heat dissipation technology, which can give full play to the cooling effect of the graphics card and keep the graphics card in a cool state.
Among the three fans, the fans on both sides rotate clockwise, and the middle fan rotates counterclockwise. This can form two independent air ducts on the upper and lower sides of the TUF RTX 3090 graphics card to help the graphics card quickly dissipate heat.
At the power interface, the TUF RTX 3090 graphics card uses dual 8-pin power supply, and its TGP (Total Graphics Power) is 350W. Next to the power supply interface, ASUS also sets two LED lights. When the power supply is insufficient, it will Lights up to remind consumers. Next to it is the iconic Logo of the TUF series, which supports RGB color adjustment and can be adjusted using the tools provided by ASUS official.
There is a hollow heat-dissipating armor on the back of the TUF RTX 3090 graphics card. Large-area openings help heat dissipation. There is a special lever near the power interface. The performance mode and silent mode can be switched by the lever to adapt to different scenarios. demand. Among the RTX30 series graphics cards, only RTX 3090 graphics cards support NVLink dual graphics card mode, so TUF RTX 3090 retains the NVLink connection board near the rear interface panel. Users can purchase a dedicated NVLink bridge to achieve RTX 3090 dual card crossfire .
On the interface panel on the back of the TUF RTX 3090, ASUS provided 3 DP ports and 2 HDMI ports this time. In order to ensure strength, ASUS used 304 steel for the interface panel this time.
The overall appearance is finished, let’s take a look at the performance of ASUS TUF RTX 3090 in common scenarios.
The RTX30 series uses the GA102 core. From the official core diagram, the GA102 core contains 7 groups of GPC units, and each group of GPC units contains 12 groups of SM units. According to the division of different models, the number of enabled SM units is also different. RTX 3090 enables 82 groups, 3080 enables 68 groups, and 3070 enables 46 groups.
From the perspective of the SM unit architecture, each SM unit contains 4 partitions. Each partition contains the third-generation Tensor Core. It also contains a hybrid unit composed of 16 FP32 units, 8 FP32+8 INT32 units, and can execute FP32. Or INT32 operation.
RTX 3090 contains 82 SM units, a total of 10496 CUDA cores, its acceleration frequency is 1.7GHz, the video memory uses GDDR6X video memory, the video memory reaches 24GB, the video memory bit width is 384bit, and it supports up to 8K HDR output.
The evaluation platform information for this experience of TNewsPro is as follows:
Next, let’s take a look at the specific performance of TUF RTX 3090 through 3DMark. In the 3DMark graphics test, we see that the ASUS TUF RTX 3090 graphics card is far ahead of the RTX 2080Ti in the DX12-based Time Spy test. Compared with the RTX 3080, the improvement is not much, and the overall improvement is about 10%.
In the Fire Strike test based on DX11, TUF RTX 3090 has a performance improvement of about 15% compared to RTX3080 in 2K and 4K scenarios. In the low-requirement 1080P scenario, TUF RTX 3090 is close to RTX 3080. 50% performance improvement.
Next, we use FurMark to test the TUF RTX 3090 graphics card. In the 1-hour baking test, the highest temperature during the ASUS TUF RTX 3090 test is only 65 degrees, and this is still without manual adjustment of the fan speed. Proceed under. During the baking machine test, the peak power consumption exceeds 350W, and the highest is about 370W. Such a huge power consumption release, if you want to experience the RTX 3090 stably, you need at least a 750W power supply.
Overall, the TUF RTX 3090 has a very good heat dissipation performance. You must know that the core temperature of the public version of the RTX 3080 graphics card can reach 70 degrees in the baking machine test. However, through the theoretical test of 3DMark, we can see that the RTX 3090 is in game performance. Compared to RTX 3080, the improvement is not much.
Next, let’s take a look at the specific performance of TUF RTX 3090 through several 3A games. Here, IT House chose “Bright Memory”, “Frontier”, “Tomb Raider: Shadow”, “German Headquarters: New Blood” Several games tested the TUF RTX 3090.
Since these games have built-in benchmarking tools, we tested and selected the highest manual image quality in 4K and 2K scenes and turned on the highest quality ray tracing and the highest quality DLSS. The test compares the AIC version of RTX 2080Ti and the public version of RTX 3080. The test data is as follows:
Through these games, we found that in 2K and 4K scenarios, TUF RTX 3090 has an overall performance improvement of about 10%-15% compared to RTX 3080. Of course, “Tomb Raider: Shadow” is limited by hardware The reason is that the improvement is not obvious in the 2K scenario. From here, we can also see that the only reason for restricting RTX30 series graphics cards in the future may be the CPU hardware.
One of the most important features of TUF RTX 3090 is undoubtedly the native support for 8K. Since there is no 8K display device, IT Home uses the DSR function that comes with the Nvidia control panel to simulate the game performance in the 8K scene. Here we are in 4K@60 frame scene. Adjust the global DRS resolution to 4 times and the DSR smoothness to 33%. It is currently known that turning on DSR to simulate an 8K display in a 4K scene will cause a 3-5% loss in performance compared to a full 8K display.
Since there are not many games that support 8K on the market, IT House uses three games “Control”, “Destiny 2”, and “Wolverine Headquarters: New Blood” to calculate the average frame rate. All three games are in high quality by default. , Turn on light tracking, and turn on DLSS. The average frame rate calculation is performed using the FrameView tool launched by NVIDIA. Due to different hardware scenes and game scenes, the test results obtained by FrameView may be different due to differences between different devices. The test results are as follows:
In the 8K DSR scene, we can see that when the TUF RTX 3090 graphics card runs the two games “Destiny 2” and “Control”, the average frame rate basically reaches 60 frames, which is a very smooth level, and the “German Headquarters: New The average frame rate of “Bloodline” is around 27 frames, reaching a smooth level.
Next, we use a special rendering tool to test the performance of the TUF RTX 3090’s video memory. Since the TUF RTX 3090 uses 24GB of GDDR6X video memory and has a memory bandwidth close to 1000GB/s, it can handle more material data than the RTX 3080. And texture data, so you can achieve faster rendering of large scenes. Here we use OctaneRender rendering tool to render the image of TUF RTX 3090, and compare the rendering capabilities of RTX 3080.
Here we use OctaneRander’s high-resolution large-scale scene for rendering. The test data is as follows:
Through the rendering test, we see that compared to the RTX 3080, the TUF RTX 3090 has a larger video memory and video memory speed, so it is faster and takes less time to render large scenes. This is also the biggest difference between RTX 3090 and RTX 3080.
In regular games, 8K games, and large-scale scene rendering, we can see that TUF RTX 3090 has a certain degree of improvement in game scenes compared to RTX 3080, which is the best in 8K games. Due to the advantages of video memory, TUF RTX 3090 is also faster than RTX 3080 in large-scale scene rendering.
to sum up
ASUS TUF-RTX3090-24G-GAMING looks tougher and thinner than the public version of the RTX 3090 graphics card. In terms of game performance, it is not much better than RTX 3080. For game-focused players, RTX 3090 It may not be a cost-effective option right now, but it is an important direction for future game development.
TUF RTX 3090 24GB of GDDR6X video memory brings more room for improvement. Under the same video memory bit width, GDDR6X has a 35% increase in memory bandwidth compared to GDDR6, and an energy efficiency ratio is reduced by about 15%.
For more players, TUF RTX 3090 represents the future. With the popularity of RTX30 graphics cards, game production will rise to a new space, with higher resolution, higher materials, and higher textures. In the future, the graphics card will process more data, which requires the graphics card to have a higher bandwidth and higher data capacity when performing graphics calculations. This is also the reason why NVIDIA has always emphasized the improvement of video memory specifications.
For those players who are pursuing the ultimate gaming experience, TUF RTX 3090 is the top gaming graphics card at this stage. At the same time, it is also a professional computing card at the current stage. For users with strong needs, ASUS TUF RTX 3090 It is a good choice for early adopters.
