Shulou(Shulou.com)11/24 Report--

On the evening of November 17, the NVIDIA Geforce RTX4080 graphics card officially went on sale. Before that, CTOnews.com has tested the performance of the public version of RTX4080 and several non-public cards, and now we have another Sotai RTX4080 16GB apocalypse OC graphics card. This video card has 5 fans, and its actual performance is very anticipated.

CTOnews.com is a test platform built for Sotai RTX 4080 16GB apocalypse OC. The specific configuration is shown below:

Appearance ID design Sotai RTX 4080 apocalypse OC card front adopts three-fan design, the fan is surrounded by a whole piece of silver scale armor, supplemented by a small amount of black painting, to increase recognition and graphics card texture, but also effectively enhance the structural strength of the front of the card.

The fan area of the three 11cm biomimetic shield scale 2.0 is very large, and the area of a single blade is larger than that of the previous generation. The scale village bionic stripes are designed on the surface and the blade curvature is optimized to improve the air volume, air pressure and air flow of the fan, and support FREEZE fan start-stop technology.

The black alloy backplane is used on the back of the video card, which provides anti-collision and anti-static protection for the internal PCB of the video card to a certain extent. The two fans on the backplane are designed for blowing and ventilation respectively, which help the overall airflow of the graphics card to flow more smoothly and dissipate heat better. At the same time, the fan cooperates with the apocalypse wing pattern on the back panel to form the glowing complete apocalypse wing 2.0, making the appearance more distinctive.

On one side of the video card, you can see a luminous sign of Sotai Logo in the center, with the words GEFORCE RTX next to it. At the top is the exposed large area thickened heat dissipation fin module. The newly upgraded VC cooling system of Sotai RTX 4080 apocalypse OC graphics card consists of a large area cooling version, high density nickel plated fins and convective penetration heat dissipation.

Sotai RTX 4080 apocalypse OC graphics card adopts semi-package design, and the fan part adopts double ball bearing design to reduce fan running friction, further reduce fan running noise and prolong fan life.

There are double BIOS switch buttons at the top of the video card to provide players with two fan control modes of acceleration and silence, and you can use the buttons on the video card to switch fan cooling strategies during the game. The 124p power supply interface is gold-plated on the metal terminal to effectively reduce oxidation and reduce the contact impedance of the power cord and interface.

There are three RGB light display areas on the front, back and top of the Sotai RTX 4080 apocalypse OC graphics card, all of which support hundreds of thousands of lamp cycle modes with 1600 million colors. The front light is composed of transparent drill-cut color breathing lamp branches, and the design of only one large fan in the middle is very rare.

After the machine is lit, the Suotai Logo light plate at the top will show the effect of a mirror translucent breathing lamp, further increasing the sense of lighting atmosphere in the chassis. And the two fans on the back will naturally light up at the same time, and show the streamer effect, together with the pattern on the back of the graphics card, to form the true wing of the apocalypse.

Simple technical analysis Sotai RTX 4080 16GB apocalypse OC is based on a new generation of NVIDIA Ada Lovelace architecture AD103 core, using TSMC 4N process, 9728 CUDA cores, 304Tensor cores and 112ROP units. Compared with the public version of RTX4080, this card also uses 24 "3-phase ultra-luxury power supply, the new 12" 4p interface, which surpasses the public version configuration and has better electrical performance.

Sotai RTX 4080 16GB apocalypse OC video memory is promoted to 16GB GDDR6X type, video memory bit width 256-bit, the biggest advantage of large video memory is no longer worry about the explosion of video memory in the game, the productivity creation is more optimized, and the graphics card core frequency 2205MHz, acceleration frequency 2580MHz, video memory frequency as high as 22.4Gbps, the promotion is very scary.

The third-generation RTX Cores benefits from Ada's new flagship architecture, which can improve light pursuit performance by up to 2 times. NVIDIA DLSS 3 has also fully evolved, adding frame generation technology compared to DLSS 2, which can predict frame-to-frame motion changes, achieve AI frame insertion, and achieve higher frame rates while maintaining image quality. These technologies are naturally better than gamers, and the performance of RTX4080 in the next generation of games is expected.

RTX4080 has shader capabilities up to 83TFLOPS and twice the throughput of the previous generation. The fourth-generation Tensor Cores can increase the throughput by four times to 1.4 TensorMurtaFLOPSMagi AI performance to two times. Dual NVIDIA encoders also support AV1 coding, which is 40% more efficient than H.264. Game anchors, video calls and video creative workers can all enjoy the improvement in picture quality and efficiency.

In terms of energy efficiency, the power consumption ratio can be increased by up to 2 times through the TSMC4N customization process. The preset power consumption of Sotai RTX 4080 16GB apocalypse OC is 320W. Considering the huge improvement in performance, the advantage of energy efficiency ratio will be more prominent.

Theoretical performance test

Let's start with the actual measurement. First of all, the test of the FurMark grill, doughnut + AIDA64 for 10 minutes, the core temperature is stable at 61.0℃, which is 3 ℃ lower than the public version of GTX4080 on the same test platform, the power consumption is 320W, and the fan speed is only 31%. It is the quietest of the several RTX4080 we have tested, and sure enough, the five fans have some advantages.

In the 3D Mark stress test, the final score of Sotai RTX 4080 16GB apocalypse OC graphics card is 99.4%, the performance release is stable, and easily exceeds the qualified rate of 97%.

In the individual test of 3D Mark, first of all, in the Time Spy test that reflects the performance of DX12 games, the score of Sotai RTX4080 16GB apocalypse OC graphics card reached 26894 points. As a comparison, the public version of RTX4080 on the same test platform scored 26552 points, GeForce RTX 3080 10G version 17306 points, RTX 3090 18981 points, and RTX 3090Ti 21862 points. Sotai RTX4080 16GB apocalypse OC graphics card leads the RTX30 system in an all-round way, and also surpasses the public version of RTX4080.

In the Fire Strike test that reflects the performance of DX11 games, the score of Sotai RTX4080 16GB apocalypse OC graphics card reached 63192 points, compared with the public version RTX4080 score of 53379 points on the same test platform, and Suotai led by nearly 10000 points. In addition, the scores of GeForce RTX 3080 10G, GeForce RTX 3090 and GeForce RTX 3090Ti are 40932, 46045 and 52630 respectively.

In the 3DMark Portal Royal light tracking test, the Sotai RTX 4080 16GB apocalypse OC card scored 17405 points, an increase of about 50% over GeForce RTX 3080, and the improvement was greater than the raster performance.

The score of Sotai RTX 4080 16GB apocalypse OC graphics card in the theoretical run gives us a big surprise. We have made a comparison table of GPU physical scores. In all projects, Sotai RTX 4080 16GB apocalypse OC has a significant improvement compared with previous generations of flagship graphics cards.

Although the theoretical performance of NVIDIA DLSS 3 parsing has surpassed that of all RTX 30 series graphics cards, the really big boost is DLSS 3 technology. DLSS 3 is a new optical flow accelerator driven by the new fourth generation Tensor Core and GeForce RTX 40 series GPU, performance multiplier technology based on AI technology, the latest version of NVIDIA deep learning supersampling technology, and groundbreaking optical frame generation technology, will usher in a new era of NVIDIA RTX neural network rendering games and applications.

The optical flow accelerator based on NVIDIA Ada Lovelace architecture can analyze two consecutive game images and calculate the motion vector data of objects and elements from frame to frame without the need for traditional game engine modeling. The frame generation model acquires both motion vector and optical flow data in the game engine, which greatly reduces the visual anomalies of AI when rendering elements such as particles, reflections, shadows and lights.

To put it simply, in the past, DLSS 2 improved the image quality and the number of frames by rendering a low-resolution image, and then AI zoomed in to high resolution. While the new DLSS 3 is compatible with DLSS 2, it also adds a frame generation function, which can insert a new frame calculated by AI between two real frames to double the number of frames. Combined with the super-resolution function of DLSS 2, AI can reconstruct up to 7/8 display pixels, and the game performance can be up to four times better than without DLSS!

So let's also take a look at the performance of the new card through actual measurement. The latest version of 3DMark has been adapted to DLSS 3's BenchMark. We can directly see the difference between the test results of Sotai RTX 4080 16GB apocalypse OC card and DLSS 2 control variables.

According to the measurement of CTOnews.com, the average frame number of Sotai RTX 4080 16GB apocalypse OC card in DLSS 2 mode is 99.41 frames, which is 2.5 times higher than that without DLSS 2.

With the latest DLSS 3 enabled, the average frame number of Sotai RTX 4080 16GB apocalypse OC cards has further increased to 127.75 frames, roughly 3.3 times higher than without DLSS 2.

Of course, the biggest problem with the new technology is whether it can adapt to new games quickly. Obviously, NVIDIA has done a very good job in this respect. Not only is the first DLSS 3 game lineup very luxurious, but as long as it is adapted to DLSS 3, it will be downwards compatible with DLSS 2, which will greatly reduce the difficulty of adaptation for developers and maximize the benefits of players. This time, we selected "Cyberpunk 2077", "Super Human", "memory of Light: infinite" and "reincarnation of Life and death" and other games that have adapted to DLSS 3 to test the Sotai RTX 4080 16GB apocalypse OC card.

First of all, the recent popular 3A game "Plague Legend: Requiem", the effect of increasing the number of frames is more obvious. By default, it can still reach less than 60 frames, but with the blessing of DLSS technology, the number of frames can be increased by about 2.5 times when it is opened to the performance file. If DLSS 3 + super performance is turned on, the number of frames can even be increased by more than three times.

The DLSS 3 option is also available in Super Human, a new book by PUBG developer Blue Hole. After opening the DLSS 3 performance file, the number of frames can be increased by 60%, and the number of frames can be doubled under the super performance of DLSS 3.

"Cyberpunk: 2077", which is a great test of GPU performance, carries out its own BenchMark test under the highest picture quality of 4K super light chase. From the results, it does put a lot of pressure on GPU performance. The number of frames when DLSS is fully off is only 75. After opening DLSS 3 and selecting the performance file, the number of frames increased to 108frames, an increase of up to 44%, directly promoted to the 3A light pursuit experience.

Next, let's test an online PC game "Magic Tower" that eats GPU performance very much. Once upon a time, "Magic Tower" was just a mobile game, but I didn't expect that the PC side actually pulled the picture quality to the maximum. NVIDIA's new graphics card features are almost all used, it provides complete RTX+DLSS 2+DLSS 3 support, and after opening RTX, the reflection on the ground is obviously more real, and the feeling of Cyber City is lifelike.

Of course, after actually turning on the light tracking effect, it really tests the performance of the graphics card. There are only less than 50 frames under the highest picture quality of 4K, so it certainly won't be very smooth to play, but when we open the performance file of DLSS 3, the number of frames has increased by nearly 1.5 times, to 116frames, which has suddenly become a competitive experience. You know, this is 4K light pursuit quality.

Game delay testing, of course, the essence of DLSS 3 technology is that AI generates new frames, so it is bound to bring the side effect of increased delay. For games that require high precision, ms-level delay differences will also affect the player's experience and feel. So after turning on the frame generation function of DLSS 3, NVIDIA Reflex will also be forced to open to minimize the rendering delay caused by the generated frame.

In Watchman: return, which is also the FPS competitive online game, the NVIDIA Reflex low latency option is also provided, which enables CPU to start submitting rendering work to GPU before the previous frame is completed, thus greatly reducing or even eliminating the rendering queue and faster response time. The measured results show that the delay is reduced by 62% when the enhanced Reflex option is turned on.

In addition to supporting DLSS 3's masterpiece, CTOnews.com has also tested several mainstream games for everyone. After all, at present, the number of "old" 3A games that support DLSS 2 is very large.

In Tomb Raider: shadow, it is measured that the Sotai RTX 4080 16GB apocalypse OC can run to 137frames while running the benchmark even without turning on DLSS at the highest 4K resolution, which is already enough for 4K / 144Hz monitors to play.

The game also supports DLSS 2 technology, and after turning on DLSS 2, the number of frames can be increased by up to 80%. All the projects are also slightly higher than the public domain, and can already challenge the future 8K games.

Finally, we tested a light-chasing 3A masterpiece "Control: the Ultimate Edition". 4K, the highest picture quality and the highest light could not catch up with the DLSS. Like the Magic Tower, it was less than 50 frames, but after turning on the DLSS, the number of frames doubled, and the experience was better. After some testing, Sotai RTX 4080 16GB apocalypse OC controls 4K games without any problems.

Creative production test Sotai RTX4080 16GB apocalypse OC has a huge improvement in computing power and video memory. With these hardware and technical upgrades, RTX4080 graphics cards will certainly bring higher efficiency and greater potential in creative production and in-depth learning. By installing the NVIDIA Studio driver, you can support more than 75 creative software to call the AI computing power of the NVIDIA CUDA core.

In modeling and rendering software, GeForce RTX4080 can use CUDA to provide hardware acceleration for work. At present, almost all modeling software will optimize the GPU of NVIDIA, so it can achieve the coexistence of efficiency, stability and compatibility. For example, in the commonly used rendering tool V-Ray, you can use RTX accelerated ray tracing to achieve high-performance final frame rendering. With the noise reduction feature of AI, GPU can further speed up interactive rendering.

In V-Ray Benchmark, Sotai RTX 4080 16GB apocalypse OC scored 3073, which can handle most modeling rendering needs.

Thanks to Ada's new flagship architecture, the performance of light chase has been greatly improved, and the score of Sotai RTX 4080 16GB apocalypse OC in V-Ray GPU RTX has increased to 4066 points, even the high rendering pressure of real-time light chase can be handled calmly.

In addition, dual NVIDIA encoders support AV1 coding. AV1 is the next generation video coding technology, which can provide faster video coding and higher quality streaming media transmission performance while occupying the same space. This encoding format is already very common in mainstream multimedia applications. For example, domestic editing software clipping professional version already supports AV1 video encoder acceleration, as well as OBS live streaming software, which also supports NVENC AV1 coding recording.

The trend of AV1 is not only the result of technological advances, but also the pain point of the industry's demand for productivity, which is to significantly compress the size of video files while ensuring that the image quality is almost unaffected.

We also carried out a simple test, through the editing professional version of the software to use H264 and AV1 these two different coding to export the same video material. In the end, the file size encoded by H264 is 159MB, while the file size encoded by AV1 is only 127MB, and the size has been reduced by 21%, but there is no difference in image quality.

Finally, there is the rendering test of PugetBench For Davinci. GPU acceleration effects based on NVIDIA CUDA technology can achieve faster real-time video editing and frame rendering, and the output speed using NVIDIA coding can be increased by up to 5 times. Sotai RTX 4080 16GB apocalypse OC scored 2547 on the test, and 8K video clips no longer need to be an agent.

To sum up, Sotai RTX4080 16GB apocalypse OC left a deep impression on me this time, not only because of its powerful hardware performance, but also because RTX4080 has strong AI computing power and technology, whether it is NVIDIA DLSS 3, DLSS frame insertion technology or NVIDIA Reflax low-latency technology, the game experience improvements they bring to players are solid, immediate and tangible.

The exterior design of the Sotai RTX 4080 16GB apocalypse OC is also interesting, and the two fans on the back can better help the graphics card vent and blow, making the heat dissipation more efficient. At the same time, the fan lights up the RGB with the apocalypse wing pattern on the back panel, which is also quite novel and unique. In short, if you have a high pursuit of graphics card performance and game experience, especially the 4K high-frame game experience, Sotai RTX 4080 16GB apocalypse OC will certainly satisfy you.
