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

Whenever NVIDIA releases a new graphics card, players' eyes always focus on a variety of non-public graphics cards. As one of the outstanding domestic AIC manufacturers, Seven Rainbow has been favored by players with outstanding design and solid and responsible warranty. On the occasion of the launch of the RTX 4090 series GPU, Qi Caihong also launched its high-end product: iGame GeForce RTX 4090 Vulcan OC.

What makes it special is that it provides two exclusive functions: magnetic smart screen and one-button overclocking. CTOnews.com also received it in advance, and in this test, we will use Seven Rainbow top family buckets to see how far the core can be squeezed by this high-end non-male RTX 4090 that supports one-click overclocking. The specific configuration is as follows:

Design Seven Rainbow iGame GeForce RTX 4090 Vulcan OC box is huge, with graphics card model and memory specifications, namely GDDR6X 24GB memory, printed on the front. Below are some of the advanced technologies it uses, such as NVIDIA DLSS, RayTracing, NVIDIA Reflex, and NVIDIA Studio.

In addition to the necessary extension cables, instructions and other accessories, the package is separately equipped with a pair of antistatic gloves and a wiping cloth.

Due to the unique positioning of the RTX 4090, the Seven Rainbow iGame GeForce RTX 4090 Vulcan OC comes with unique magnetic smart screen components and installation tools. In addition, a triangular bracket is provided to support the weight of the graphics card.

In terms of the graphics card body, the Seven Rainbow iGame GeForce RTX 4090 Vulcan OC graphics card adopts a 3-fan design, the overall color matching is iron black, and the all-metal frame is inspired by the "post-cyber era". The size of the product is 348.5*159.5*70.4mm, which is a large graphics card occupying three and a half slots.

Seven rainbow iGame graphics Logo and the English letter Logo are printed in the center of the fan, and there are various styles of irregular metal decoration around it. The fan specification is 104mm large diameter, 9 blades, using the "air sickle ring" design.

The back of the Seven Rainbow iGame GeForce RTX 4090 Vulcan OC graphics card has a brushed metal texture, with an irregular window design and triangular Logo decorative piece on the right.

Inside the window is a set of heat conducting fins, which are officially called "reflow soldering" to ensure that the fins are closely welded to the heat pipe.

The side of the graphics card is the other side of the heat dissipation module, which is also covered with heat dissipation fins, nine 8mm heat pipes are built in, the right side and bottom are wrapped by a metal exoskeleton and a metal middle frame, and there is a platform for connecting the magnetic smart screen in the lower side, which is connected by metal contacts.

The small screen also supports separate placement of the external extension cord and the base to become part of the "desktop aesthetics" of hardware enthusiasts.

In the Seven Rainbow Control Center iGame Center, you can customize this screen in detail.

The I / O metal bezel of the Seven Rainbow iGame GeForce RTX 4090 Vulcan OC graphics card is equipped with 3 DP1.4 ports and 1 HDMI2.1 interface to support up to 8K output. The biggest bright spot is the physical button that can overclock with one button, which is the patented design of Seven Rainbow, so that overclocking can be easily done by rookies.

Finally, it is the effect of the "iGame host" building block toy with the iGame GeForce RTX 4090 Vulcan OC graphics card on the table made by Seven Rainbow iGame combined with Qiqi building blocks. If you are interested in the surroundings of this geek table, you can go to WeChat Mini Programs to search "COLORFUL official flagship store" to buy the same model.

Technical analysis: the first three models of the GeForce RTX 40 series are GeForce RTX 4090, GeForce RTX 4080 16GB and GeForce RTX 4080 12GB Game GeForce RTX 4090 Vulcan OC, which is based on the most high-end AD102 core, with 16384 CUDA cores, 512 Tensor cores, 128optochase cores, 512 texture units and 176ROP units, which is more than half the size of the previous generation RTX 3090 core. There should also be true flagship RTX 4090 Ti to unlock the remaining 2 GPC units.

The core frequency of GeForce RTX 4090 is 2235-2520MHz, while iGame GeForce RTX 4090 Vulcan OC can reach 2625MHz by default when one-button overclocking is enabled, which is more than half higher than that of the previous generation. The video memory is still 384-bit 24GB GDDR6X, but the bandwidth is up to 1TB / s. TDP is 450W by default, and TDP can reach 510W after one-click overclocking, which is similar to the non-public version of RTX 3090 Ti and a full 160W increase compared to RTX 3090.

The architecture of GeForce RTX 4090 has also changed a lot, upgrading to the latest NVIDIA Ada Lovelace architecture. It is based on TSMC custom 4N process, so it achieves a leap of up to 2 times the ratio of performance to power consumption. Streaming multiprocessors have up to 83 TFLOPS of coloring capacity and twice the throughput of the previous generation. The effective ray tracing computing power of the third generation RT Cores is 191 TFLOPS, which is 2.8 times that of the previous generation. The fourth generation of Tensor Cores adds a new FP8 engine with up to 1.32 petaflops of Tensor processing performance, which is five times higher than that of the previous generation. SER brings up to three times the performance improvement for RayTracing, and up to 25% improvement for overall game performance.

The above data may be abstract. Reflected in the concrete functions, the new architecture has brought a lot of new functions. Due to the introduction of dual NVENC encoders, it adds support for AV1 coding, which can reduce the video export time by up to half. It is precisely because of the introduction of the Ada optical flow accelerator that 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. In short, it is suitable for game production.

One of the most important technology upgrades at the press conference was 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.

The new 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 modeling using the motion vectors of traditional game engines. This greatly reduces AI's visual anomalies when rendering elements such as particles, reflections, shadows, and lighting.

To put it simply, the past DLSS 2 was to render a low-resolution image, and then AI zoomed in to high resolution to achieve both the image quality and the number of frames. While the new DLSS 3 is compatible with DLSS 2, it also adds a frame insertion function, which can insert virtual frames 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, up to four times better than without DLSS!

There is no evidence of word of mouth, let's go straight to the test. The latest version of 3DMark has been adapted to DLSS 3's BenchMark. We can directly see the difference by comparing the test results of iGame GeForce RTX 4090 Vulcan OC with the control variables of DLSS 2. Measured in DLSS 2 mode, the average number of frames is 135frames, which is more than twice as high as that without DLSS 2.

But if we turn on the latest DLSS 3 technology, the number of frames on the iGame GeForce RTX 4090 Vulcan OC card goes straight to an average of 166frames, more than three times higher than without DLSS. As for the specific increase in the number of game frames, we will test it later.

Currently, DLSS 3 has been supported by many of the world's leading game developers, with more than 35 games and applications announcing upcoming support for the technology, such as "SUPER PEOPLE", "reincarnation of Life and death" (Loopmancer), "Justice 'Fuyun Court'" (Justice' Fuyun Court'), "Microsoft simulated Flight" (Microsoft Flight Simulator), "Plague Legend: Requiem" (A Plague Tale: Requiem) will provide DLSS 3 support.

Stress test-how much progress will a non-public flagship such as the theoretical running score make on the basis of the public domain graphics card? Next, we conduct a theoretical test, the first is a single baked doughnut, after 15 minutes, the core temperature is stable at about 59 ℃, the power consumption is stable at about 510W, which is higher than the public version of 440W-450W, and accords with the TDP after one-button overclocking. But it also means that the GeForce RTX 4090 does have a special power supply. If equipped with i7 / i9 such a level of processor, or honestly more than 1000W power supply, at least 850W power supply is not false.

Next, there is a 3DMark pressure test, which can detect whether the performance of the graphics card has declined under continuous running minutes. Generally, more than 97% can be regarded as a qualified graphics card. The score of the measured iGame GeForce RTX 4090 Vulcan OC is 99%, and there is almost no frequency reduction, which perfectly passes the test.

In the 3DMark TimeSpy DX12 test, the iGame GeForce RTX 4090 Vulcan OC card scored 35180, compared with 34725 for GeForce RTX 4090 and 18981 for RTX 3090.

We also tested the performance comparison between turning off one-button overclocking and turning on one-button overclocking. After turning off one-button overclocking, the score of TimeSpy Extreme is 18587 points, but after opening it, it increases by about 4.5% to 19450 points. It seems that the improvement of one-button overclocking is visible to the naked eye, so the following tests are all carried out in one-button overclocking mode.

In the 3DMark Fire Strike DX11 test, the iGame GeForce RTX 4090 Vulcan OC card scored 76434, compared with 75013 for GeForce RTX 4090 and 46045 for GeForce RTX 3090. This score means that all games can be run smoothly at 4K resolution, and even light chase games and VR games can meet the needs of high refresh rates.

In the 3DMark Portal Royal light pursuit test, the iGame GeForce RTX 4090 Vulcan OC scored 25312, higher than the 25080 score of the public version of RTX 4090. In the past, GeForce RTX 3090 can experience light-chasing games smoothly at 2K resolution, while RTX 4090 can already play smoothly at 4K resolution.

The actual measurement of the game is reflected in the actual game, how much improvement can DLSS 3 bring? 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 for testing. In addition, we will test the Demo "Enemies" of a Unity engine.

First of all, we test the domestic knight-errant online game "against the cold", also provides RTX ray tracing and DLSS 3 options. Let's turn on the 4K highest image quality to try its frame number performance. As can be seen from the data below, it is almost impossible to play without turning on DLSS, and the frame rate has increased nearly fivefold after turning on DLSS 3. 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 BenchMark, and we can see that there is little difference between the balance between DLSS and DLSS. Due to the existence of anti-aliasing, it is even more pleasing to the eye after opening DLSS. This is the charm of AI technology.

In the "Cyber punk 2077" graphics card killer, we can run its own BenchMark in 4K super light chase mode, and get the following data. IGame RTX 4090 Vulcan can run Super Light-chasing Cyberpunk 2077 at a native 4K resolution. On the premise of driving to the DLSS super performance gear, it can achieve 4K144Hz play, for super enthusiasts, it can even meet the 8K60 frame play.

Next up is Demo "Lyra", a game made using 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 1.7 times. Compared with the DLSS 2 in the same gear, it has also increased by nearly 20%.

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. GeForce RTX 4090 has nearly tripled the number of frames after opening DLSS 3, and the 4K rendering is silky and smooth.

In terms of clothing texture and hair rendering, which are difficult for AI, there is only a slight difference in image quality between turning on DLSS and turning off DLSS, which is difficult to see on a 4K monitor. It can be said that with the help of the AI of DLSS 3, 4K light chasing games will eventually become popular and become standard in all kinds of games.

So is DLSS 3 technology perfect? Of course not. The essence of DLSS 3 is frame insertion, and frame insertion must have a side effect of 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. Therefore, when you turn on the frame insertion function of DLSS 3, NVIDIA Reflex will be forced to open to make up for the rendering delay caused by frame insertion as much as possible. From the test data, we can see that the delay after turning on DLSS 3 is even slightly lower than nothing. If you want to pursue absolute low latency, you can turn off DLSS, open NVIDIA Reflex alone, and enjoy the ultimate e-sports experience.

In Tomb Raider: shadow, it is measured that running BenchMark at the highest resolution of 4K can run up to 180 frames, which is enough for 4K144Hz monitors to play.

The game is also supported by DLSS, but the version is older, so the effect is definitely not as obvious as DLSS 3, with an average of 218 frames under the measured DLSS.

Finally, we tested a light chase 3A masterpiece "Control". The 4K highest quality and highest light can only barely play smoothly for 72 frames, while the iGame RTX 4090 Vulca almost doubled the number of frames after turning on DLSS. This 4K game experience is quite excellent.

Creative production to the level of RTX 4090, certainly not just playing games, creative production and deep learning is the main audience. The iGame RTX 4090 Vulca is also a NVIDIA Studio certified GPU. At present, there are more than 75 creative applications that can use AI computing power to greatly improve productivity.

In modeling and rendering software, GeForce 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.

When V-Ray Benchmark turns on CUDA acceleration, the score reaches 4311, which is higher than that of more than 4200 in the public domain, setting a record for us.

Thanks to the improved performance of light pursuit, the score of iGame RTX 4090 Vulcan in V-Ray GPU RTX has also increased to 5870, which is also slightly higher than that of the public card, which is sufficient for heavy rendering of real-time light pursuit.

In the later part of the video, the RTX 40 series GPU added support for 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. NVIDIA works closely with a number of industry partners, and today's mainstream multimedia applications can support AV1. At present, the domestic professional versions of Wanxing Maoying and clipping already support AV1 video acceleration.

OBS LVB software also supports AV1-encoded recording. It is hoped that AV1-encoded LVB can be adapted as soon as possible, thus greatly saving LVB bandwidth.

The 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 iGame RTX 4090 Vulcan can reach 2687, which is even higher than the 2610 in the public edition.

To sum up, nothing attracts more attention than the unique magnetic smart screen of the iGame GeForce RTX 4090 Vulcan OC Vulcan graphics card. There are a lot of graphics cards on the screen, and not many of them can be removed as a desktop decoration. For players with personalized graphics cards, the Seven Rainbow iGame GeForce RTX 4090 Vulcan OC is indeed a good choice. In terms of performance, RTX 4090 can meet all the requirements of 3A with high frame number at 4K resolution. With such strong performance, coupled with the blessing of DLSS 3, even 8K games can be challenged.

If you are a game enthusiast who wants to experience 4K144Hz, then iGame GeForce RTX 4090 Vulcan OC, a personalized graphics card that takes into account both design and tough performance, will be a good choice for RTX 4090 non-public cards, which will be sold on JD.com, Tmall, Douyin, Kuaishou and other e-commerce platforms and national distribution and retail channels at 9: 00 p.m. on October 12. In addition, the Seven Rainbow Tomahawk GeForce RTX 4090 Deluxe and iGame GeForce RTX 4090 Neptune OC will also go on sale with iGame 4090 Vulcan, priced between 12999 and 14999 yuan.
