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

RTX 4090 as the annual flagship of NVIDIA's debut, various AIC manufacturers will certainly try their best to pile up all their cool techs. But this often leads to high premiums and design redundancy. On the other hand, the RTX 4090 metal master OC, who started here, won my heart. Its overall design style is simple and tough, and ensures strong heat dissipation, which is a clear stream in the RTX 4090 debut series.

CTOnews.com received the shadow RTX 4090 metal master OC in advance. In this test, we filled all the configurations to avoid creating a bottleneck to this performance monster. The specific configuration is as follows:

The exterior design shadow RTX 4090 metal master OC graphics card is packaged in METALTOP series silver style, with the product model of metal master Logo,RTX 4090 made up of metal instruments on the front of the package, with a 3-year warranty and personal guarantee.

There are graphics card body, 12VHPWR to 4*8Pin extension cable and a set of graphics card support rod kit in the package. RTX 4090 due to the upgrade of heat dissipation, the whole card has become a giant graphics card occupying three and a half slots, so you must top it with a support bar when installing the card horizontally, otherwise it may cause the bezel to be bent when you move it.

Shadow RTX 4090 metal master OC graphics card adopts three-fan design, the outside of the card is wrapped with a circle of silver metal armor, the edge is made of CNC technology, and the surface is covered with stripes.

The fan body is black, the middle is printed with white metal master Logo, the fan diameter 102mm, 20mm thick 11 blades design, the three-stage structure of the blade is the characteristics of the metal master series, and supports intelligent start and stop function.

Shadow RTX 4090 metal master OC graphics card backplane uses gray brushed metal design, surrounded by a circle of silver and white embellishment. The backplane pattern is symmetrical, and the right side is a hollowed-out heat dissipation hole.

Through the hollowed-out heat dissipation hole, the internal heat dissipation fin can be seen.

There are also hollowed-out heat dissipation holes on the front side and the right side. Yingchi RTX 4090 metal master OC graphics card adopts cold light star δ (Delta) heat dissipation system, equipped with 4 * Φ 8mm x 4* Φ 6mm nickel-plated composite heat pipe, large area heat soaking plate and 6 groups of heat dissipation fins.

Yingchi RTX 4090 Metal Master OC card has three hollowed-out heat dissipation ports on the front and side, with Geforce and GALAX logos printed on the left and right.

There is also a set of 16pin interfaces above the heat dissipation hole in the middle, which currently does not have most of the power supply, so it needs to be converted to this 16pin interface through the 4 8Pin interfaces attached to the package.

The I / O bezel is equipped with 3*DP1.4 interface and 1*HDMI2.1 interface, which supports up to 8K video output and is fixed with three screws on each side.

Specification resolution Shadow RTX 4090 Metal Master OC is based on the most high-end AD102 core of NVIDIA, with 16384 CUDA cores, 512 Tensor cores, 128light 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 Yingchi RTX 4090 Metal Master OC is 2235-2565MHz, which is slightly higher than the public domain. The video memory is the 24GB GDDR6X of 384-bit, but the frequency reaches the equivalent 21Gbps and the bandwidth is increased to 1TB / s. The TDP is 450W, which reaches the grade of RTX 3090 Ti, and increases a full 100W compared to RTX 3090. It is recommended to match more than 850W power supply.

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. ‏

‏ theoretical performance ‏‏ ‏

‏, how much progress will be made in the theoretical performance of the RTX 4090 metal master OC compared to the public version of RTX 4090? Next, we conduct a theoretical test, the first is a single-baked doughnut. After 15 minutes, the core temperature is stable at 67.2 ℃ and the power consumption is about 445W. This power consumption and heat dissipation performance is basically the same as that of the public version of RTX 4090. The fan is also far from fully loaded and is quieter to use than the public version of the double fan. ‏

‏ then carries out the 3DMark 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 ‏ RTX 4090 metal master OC ‏ is 99.6%, which is the highest among the RTX 4090 graphics cards we have tested so far. ‏

‏ scored 35280 points on the ‏ RTX 4090 metal master OC ‏ graphics card in the 3DMark TimeSpy DX12 test, slightly higher than the 34720 in the public edition. It seems that some of the default increases in frequency still work. ‏

‏ in the 3DMark Fire Strike DX11 test, ‏ shadow RTX 4090 metal master OC ‏ graphics card score of 75605, also slightly higher than the public edition of 75013 points, this score means that almost 8K resolution can run almost all games smoothly, even 4K light chase games and VR games can meet the needs of high refresh rate. ‏

‏ in the 3DMark Portal Royal light pursuit test, ‏ shadow RTX 4090 metal master OC ‏ scored 25558 points, the improvement is greater than the grating performance. Almost double that of GeForce RTX 3090. 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. ‏

‏ DLSS 3 details: although the theoretical performance of ‏‏ has been improved by nearly 80%, NVIDIA is not satisfied with this. 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. ‏

‏ '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 DLSS 3's BenchMark. We can directly see the difference between the test results of ‏ RTX 4090 metal master OC ‏ and DLSS 2 control variables. Measured in DLSS 2 mode, the average number of frames is 131frames, which is more than twice as high as that without DLSS 2. ‏

‏ but if we turn on the latest DLSS 3 technology, the frame count goes straight to an average of 162frames, which is more than three times higher than that without DLSS, which is quite significant. ‏

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 ‏ Shadow RTX 4090 metal master OC ‏. 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. It can be seen that the improvement of DLSS 3 is very obvious. On the premise that it is turned on to the super performance gear, the frame number of DLSS 3 is 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 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. ‏ shadow RTX 4090 metal master OC ‏ after opening DLSS 3, the frame number soared by nearly 2.5 times, and the 4K rendering was as smooth as silk. ‏

‏ in terms of picture quality, there is little difference in definition between turning on DLSS and turning off DLSS, but you can clearly feel that the picture of DLSS blessing will be sharper. ‏

‏↑ left DLSS off, right DLSS 3 on ‏

‏, 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 the new online "watch vanguard" and "return", this e-sports delay is particularly important. Even at 4K resolution, the number of frames can even reach the upper limit of 600 frames, and a high number of frames means a reduction in latency, especially for shooter games that count against time. ‏

‏ 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. ‏

‏ finally we tested a light chase 3A masterpiece "Control", 4K the highest picture quality can not open the DLSS can only barely smooth play, while ‏ shadow RTX 4090 metal master OC ‏ directly doubled the number of frames after opening DLSS, this experience is quite excellent. ‏

‏ 's creative production of ‏ Shadow RTX 4090 Metal Master OC is not limited to ‏ playing games, creative production and deep learning are also the main audience. Nowadays, AI painting is so popular that many geeks want to use RTX 4090 to train their AI. 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 scored an astonishing 4411 points, 200 points higher than the public card and an all-time high. ‏

‏ benefits from the improvement of light pursuit performance, ‏ shadow RTX 4090 metal master OC ‏ in V-Ray GPU RTX score also increased to 5974 points, 150 points higher than the public version of RTX 4090, enough to cope with the heavy rendering of real-time light pursuit. ‏

‏ finally let's take a look at another rendering software, Octane, which can achieve fast interactive rendering through RTX accelerated ray tracing and OptiX noise reduction with AI. The final test results show that its rendering capability is equivalent to up to 27 GTX 980s working at the same time, one more than the public version of RTX 4090, which is ridiculously strong. ‏

‏ 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. ‏ Shadow RTX 4090 Metal Master OC ‏ can score 2623, slightly higher than the public version of RTX 4090. ‏

‏ in addition, NVIDIA also provides NVIDIA Broadcast as an artifact for RTX GPU. Through artificial intelligence technology, it realizes some practical effects, such as audio noise reduction, green screen matting, portrait focus and so on. ‏

‏ now I use a simple set of USB cameras and microphones for live streaming at home. Even if there is only one camera on such a computer, with the help of RTX GPU, I can choose NVIDIA Broadcast applications in all kinds of applications. ‏

‏ summed up ‏‏ as a minimalist, the author still prefers the design style of Yingchi. Simple but not simple, it can be well matched in any chassis. In terms of heat dissipation, it also achieves a better effect than the public version. Although the testing time is very tight, the author is still shocked by the performance of ‏ RTX 4090 metal master OC. It can meet all the requirements of 3A with high frame number at 4K resolution. With such a strong performance, coupled with the blessing of DLSS 3, even the popularity of 8K games is expected in the future. ‏

If you also like this minimalist design style, then Shadow RTX 4090 Metal Master OC will be a good choice for your non-public graphics card. At the beginning of the shelves, you might as well pay attention to it. I believe there will be surprises on the price.
