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

RTX 4090 has been on the market for a while, and many local tycoons have already installed it. In the existing consumer comments, the author noticed that a non-public graphics card has received a lot of praise, it is Sotai RTX4090 AMP EXTREME AIRO. The reason why it is praised, because its lighting design is very outstanding, round as water light belt can also be well integrated into the side through the chassis, so it has become a good heart of DIYer.

CTOnews.com also received Sotai RTX4090 AMP EXTREME AIRO, and in this test, unlike the previous tests, we upgraded the CPU configuration to i9-13900K, which really achieved bottleneck-free performance testing. The specific configuration is as follows:

Design Sotai GeForce RTX 4090 AMP EXTREME AIRO graphics card is also a 3.5 slot giant graphics card, three-dimensional is 35.5*16.6*7.2cm. The overall use of silver-gray painting, and the fan frame shape is unique, round and does not fully cover the bottom of the heat dissipation module, the edge has done a large area of highlight chamfering and oblique cutting treatment. Officials say the design was inspired by aerodynamics.

The Suotai GeForce RTX 4090 AMP EXTREME AIRO graphics card is designed with three fans. The diameter of the fan is 11cm. Each fan is composed of 9 black blades. The scale bionic stripes on the blade surface can improve the fan efficiency. The middle is embellished with gold brushed texture and printed with Suotai graphics and English Logo. Look carefully, there is a horizontal bar texture decoration on the outer frame of the spacer part of the fan.

The backplane of the Sotai GeForce RTX 4090 AMP EXTREME AIRO graphics card is also rounded, and an alloy is added to strengthen the bone structure to ensure that the PCB is subjected to uniform force. A large graphic Logo is printed on the left side of the backplane, which supports RGB lighting. A quasi-wind aerodynamic depression texture is added to the middle area of the backplane, and there are three 1-group hollowed-out holes on the right.

The outermost ring on the back of the video card is a white edge with the Geforce RTX logo printed on it.

Seen from the side, the outer frame of the Sotai GeForce RTX 4090 AMP EXTREME AIRO card looks like it is embedded from the right side, and the sense of streamlined design is very strong. Below the outer frame is a dense heat dissipation grille with a heat dissipation module consisting of 9 heat pipes and an oversized VC soaking plate.

The Suotai GeForce RTX 4090 AMP EXTREME AIRO graphics card adds a streamlined side light belt on the other side of the frame, which will show the hidden Sotai English Logo and graphic Logo when the light is on. Officials call it the Hongqiao Phantom Design, inspired by the Rainbow Bridge in Nordic mythology.

On the right side, there are small RGB lights distributed on the outer frame of the arc. After lighting, the graphics card will have a more three-dimensional hierarchical sense. It is not difficult to see that there are a lot of RGB elements in this card as a whole.

The I / O interface bezel adopts dark gray color matching, and the overall area is larger. The interface is equipped with 3*DP1.4 interface and 1*HDMI2.1 interface, and the highest 8K60 frame output is supported.

Above the middle area of the side of the Sotai GeForce RTX 4090 AMP EXTREME AIRO graphics card, there is a double BIOS toggle switch that players can choose from acceleration mode or silent mode to adjust the cooling strategy of the fan. The following tests will be conducted in accelerated mode.

‏ theoretical performance ‏ Sotai RTX4090 AMP EXTREME AIRO is also based on the most high-end AD102 core of NVIDIA, with 16384 CUDA cores, 512 Tensor cores, 128optical cores, 512 texture units and 176ROP units, which is more than half the size of the previous generation RTX 3090 core. The core frequency of Sotai RTX4090 AMP EXTREME AIRO is 2235-2580MHz, which is slightly higher than the public version. The video memory is the 24GB GDDR6X of 384-bit, but the frequency reaches the equivalent 21Gbps.

The architecture of ‏ RTX 4090 has also changed a lot, upgrading to the latest NVIDIA Ada Lovelace architecture. It is based on the TSMC 4N NVIDIA custom process, thus achieving a leap in performance and power consumption of up to 2x. In particular, great breakthroughs have been made in AI and ray tracing capabilities. In terms of specific functions, the new architecture brings a lot of new functions: due to the introduction of Ada optical flow accelerator, DLSS 3 can predict the motion changes between frames in the scene, realize AI frame insertion, and improve the frame rate while maintaining the image quality. At the same time, it supports the application of dual AV1 encoder, which can not only shorten the video export time, but also have better picture quality. ‏

‏ ‏

‏ next we conduct a theoretical test, the first is a single-baked doughnut, after 15 minutes, the core temperature is stable at 68.2 ℃, power consumption is stable at about 450W, this power consumption and heat dissipation performance is basically the same as the public version of RTX 4090. But the fan has a lower speed and is quieter to use than the public version of the double fan, so the RTX 4090 series non-public cooling system is obviously superfluous. In the baking machine, the author also carries on the double baking of CPU, and the final power consumption of the whole machine is about 750W. It can be said that the 850W power supply is barely enough for i9+RTX 4090, but a power supply of at least 1000W is recommended. ‏

‏ then carries out the 3DMark FireStrike stress test, which can detect whether the performance of the graphics card has declined under continuous running minutes. Generally, more than 97% of the graphics card is considered qualified. The measured score of ‏ Sotai RTX4090 AMP EXTREME AIRO ‏ is 99.2%, which perfectly passes the test. ‏

‏ in the 3DMark TimeSpy DX12 test ‏ Sotai RTX4090 AMP EXTREME AIRO ‏ graphics card score reached 35635 points, much higher than the public version of 34720 points, it seems that Suotai did some pre-overclocking at the factory. ‏

In ‏ 's 3DMark Fire Strike Extreme DX11 test, the score of ‏ Sotai RTX4090 AMP EXTREME AIRO ‏ graphics card reached 44428, which is also slightly higher than that of the public edition, which means that almost all games can run smoothly at 8K resolution, even 4K light chasing games and VR games can meet the needs of high refresh rates. ‏

‏ in the 3DMark Portal Royal light pursuit test, ‏ Suotai RTX4090 AMP EXTREME AIRO ‏ scored 25465 points, almost double that of GeForce RTX 3090, and basically consistent with Lao Huang's presentation at the press conference. In the past, RTX 3090 can experience light-chasing games smoothly at 2K resolution, while RTX 4090 can already play smoothly at 4K resolution. ‏

‏ DLSS 3 details one of the most important technology upgrades at the ‏‏ launch is DLSS 3. The DLSS 3 is an AI-driven performance multiplier powered by the new fourth-generation Tensor Core and GeForce RTX 40 Series GPU's new optical flow accelerator, the latest version of NVIDIA's acclaimed deep learning supersampling technology and groundbreaking optical multi-frame generation that will usher in a new era of NVIDIA RTX neural network rendering games and applications. ‏

‏ 's NVIDIA Ada Lovelace-based Optical flow Accelerator can analyze two consecutive game images and calculate frame-to-frame motion vector data for objects and elements without the need for traditional game engine modeling. The multi-frame generation model simultaneously acquires the 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. ‏

‏ 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 zooming in to a 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. In practice, DLSS 3 is more suitable for adding a higher number of frames to a higher number of frames. Therefore, it is necessary to combine the super-resolution function of DLSS 2 to make the original low frame count higher first, and then use DLSS 3 to become higher. AI can reconstruct up to 7/8 pixels in a set of operations. ‏

‏ said that there is no proof, let's go straight to the test. The latest version of 3DMark has been adapted to the BenchMark of DLSS 3. We can directly see the difference between the test results of ‏ Sotai RTX4090 AMP EXTREME AIRO ‏ and the control variables of DLSS 2. In DLSS 2 mode, the average frame number is 136frames, which is about 2.5 times higher than that without DLSS 2. ‏

‏ but if we turn on the latest DLSS 3 technology, the number of frames goes straight to an average of 169frames, which is more than three times higher than that without DLSS, and the extra 30 frames are the number of frames inserted by DLSS 3. ‏

At present, ‏ DLSS 3 has adapted a lot of new games, as long as it adapts to DLSS 3, it can be downwards compatible with DLSS 2, so it is very easy to develop, so it is certain that more and more developers will join the DLSS camp. We selected "Cyberpunk 2077", "Cold against the current" and "Unreal engine 5: Lyra", which have been adapted to DLSS 3, and Demo to test ‏ Sotai RTX4090 AMP EXTREME AIRO ‏. In addition, we will test the Demo "Enemies" of a Unity engine. ‏

‏ is first of all the graphics card killer "Cyberpunk 2077". We ran its own BenchMark under the 4K highest quality super light chase ‏ gear and got the following data. On Suotai RTX 4090, the improvement of DLSS 3 is also very obvious. On the premise that both of them are turned on to the super performance gear, the frame number of DLSS 3 is nearly 50% higher than that of DLSS 2 and 2.5 times higher than that of DLSS. ‏

‏ in the domestic martial arts online game "against the cold", also provides RTX ray tracing and DLSS 3 options. As can be seen from the data below, DLSS 3 is even better than Cyberpunk 2077 in "against the current". Leaving DLSS on is almost unplayable, and when DLSS 3 is turned on, the frame rate increases nearly fivefold. Compared with the DLSS 2 in the same gear, it has also increased by nearly 65%. ‏

‏ in terms of picture quality, we chose a detail in the scene, and we can see that DLSS does reduce the rendering resolution, but on a scale like 4K display, the difference is not big. ‏

‏↑ left DLSS closed, right DLSS 3 balanced ‏

‏ is followed by a game called Demo Lyra, which uses the Unreal 5 engine. The Unreal 5 engine provides full support for RTX ray tracing, DLSS 3 and NVIDIA Reflex, so there will be a large number of 3A masterpieces based on the Unreal 5 engine (such as "Black Myth: Wukong"). ‏

‏ DLSS 3's performance in Lyra also met expectations. When DLSS 3 is turned on, the frame rate increases by nearly 2.5 times. Compared with the DLSS 2 in the same gear, it has also increased by nearly 10%. Compared to the i9-12900K we tested earlier, the performance of RTX 4090 has been further released due to the removal of CPU bottlenecks. ‏

‏ in addition to the unreal engine, the Unity engine also provides full support for RTX ray tracing, DLSS 3, and NVIDIA Reflex. Finally, we tested an exploding Demo "Unity:Enemies". This Demo does not have so many gears to choose from, so you can only adjust the switch. ‏ Sotai RTX4090 AMP EXTREME AIRO ‏ has nearly tripled the number of frames after opening DLSS 3, and the 4K rendering is silky and smooth. ‏

‏, is DLSS 3 technology perfect? Of course not. The essence of DLSS 3 is that AI generates new frames, and one of the side effects of generating frames must be increased latency. After all, our mouse is the feedback on the frame we see, while AI adds additional frames, which has a great impact on competitive games. So when you turn on the frame generation feature of DLSS 3, NVIDIA Reflex will force it on to minimize the rendering delay caused by the generated frame. In actual testing, the average delay after turning on DLSS 3+NVIDIA Reflex is even lower than that of turning on nothing. ‏

‏ in the new online "watch vanguard" and "return", this e-sports delay is particularly important. A high number of frames means a reduction in latency, especially for shooter games that count against time. In addition to increasing the number of frames, optimizing the rendering pipeline can also reduce average latency, which is the principle of NVIDIA Reflex. ‏

‏ also supports NVIDIA Reflex low latency in ‏, which enables CPU to submit rendering work to GPU before completing the previous frame, which greatly reduces or even eliminates the rendering queue, resulting in faster response time and higher aiming accuracy. ‏

In addition to the above-mentioned games using new technologies, we have also tested two traditional 3A masterpieces. In Tomb Raider: shadow, it can reach 192 frames even without DLSS at the highest resolution of 4K, making it easy to play smoothly.

After turning on DLSS, the number of frames soared to 268 frames. Not to mention 4K, 8K smooth play is no longer a problem.

At the end of ‏, we tested a light-chasing 3A masterpiece "Control". In 4K, DLSS can barely play smoothly without the highest image quality, while ‏ Sotai RTX4090 AMP EXTREME AIRO ‏ doubles the number of frames directly after turning on DLSS, which is an excellent experience. ‏

‏ creatively produces ‏ as the top graphics card in RTX4090. Sotai RTX4090 AMP EXTREME AIRO's role is not limited to ‏ playing games, creative production and in-depth learning are also the main audience. RTX 4090 can also greatly increase productivity by accelerating more than 75 creative applications through NVIDIA Studio. ‏

‏ in modeling and rendering software, RTX 4090 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. ‏

‏ V-Ray CUDA Benchmark has a score of 4387, which is about 200 points higher than the public card, and it seems that increasing the frequency is very useful in modeling software. ‏

‏ benefits from the improvement in light pursuit performance, and ‏ Sotai RTX4090 AMP EXTREME AIRO ‏ 's score in V-Ray GPU RTX has also increased to 6048 points, nearly 200 points higher than the public version of RTX4090, which is enough to cope with heavy rendering of real-time light pursuit. ‏

‏ in the later part of the video, the GeForce RTX 40 series are equipped with eighth-generation NVIDIA NVENC encoders to support AV1 coding and dual encoders. 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. ‏

‏ NVIDIA works closely with a number of industry partners, and today's mainstream multimedia applications can support AV1. At present, the domestic professional version of editing and projection has supported the acceleration of NVIDIA's AV1 video encoder. OBS LVB software also supports AV1-encoded recording of NVENC. It is hoped that AV1-encoded LVB can be adapted as soon as possible, thus greatly saving LVB bandwidth. ‏

‏ commonly used video color editing software DaVinci also provides support for AV1 coding, as a free open source coding, there will be more and more mainstream software to join. ‏

‏ CTOnews.com tested PugetBench For Davinci for everyone. 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. The final score of ‏ Sotai RTX4090 AMP EXTREME AIRO ‏ can reach 2947, which is perfect for i9-13900K. ‏

In post-video software such as PugetBench For Pr and Ae, RTX 4090 can also take advantage of the signature Cuda acceleration to greatly speed up the video preview and export process. The score of the measured PugetBench For Pr reaches 1646, which is the highest score we have ever measured.

The PugetBench For Ae score is 1674, making it easy to do heavy special effects fluently.

‏ concluded that ‏, like most RTX4090 non-public graphics cards, Sotai RTX4090 AMP EXTREME AIRO also showed extremely strong heat dissipation capacity and performance beyond the public card. But what is different from other non-public graphics cards is that the overall round design of Sotai RTX4090 AMP EXTREME AIRO is quite different from this year's general pursuit of strong right angles. For DIYer people who like this design style, it is really a rare choice at the moment.

At present, Sotai RTX4090 AMP EXTREME AIRO is on sale, so if you are interested, you might as well pay attention to it.
