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

If you ask an installation enthusiast to name a water-cooled graphics card immediately, the Seven Rainbow iGame Water God (Neptune) series will be the first to think of. The Water God has always been known for its strong heat dissipation performance. Our protagonist today, iGame GeForce RTX 4080 16GB Neptune OC (hereinafter referred to as iGame GeForce RTX 4080 Water God) is no exception.

CTOnews.com also received the iGame GeForce RTX 4080 non-public graphics card in advance. In this test, we will still fill up all the configurations, and we will also briefly test its overclocking potential. The specific configuration is as follows:

Appearance design: silver armor, streamer embellishment want to buy water god consumers, only care about two points: overclocking and appearance. The appearance of the water god never disappoints. The silver-white armor of iGame GeForce RTX 4080 is very strong, and the connected cold row is also designed in pure white, which is very suitable for matching with pure white side transparent chassis.

Take a closer look at the graphics card body, you can see two water wave-shaped light strips, which is the unique "wave" RGB lighting system of the water god graphics card.

After lighting, the lamp effect flows quietly and gurgling. Provide players with full of artistic wave RGB light effect.

The back of the graphics card body also has a blue Logo, which echoes with the silver metal shell, giving rise to an advanced sense.

In the cold discharge part, three 12cm fans are used to dissipate heat to ensure that the temperature of the water body can be derived quickly.

These three fans also support ARGB dimming. With our Seven Rainbow family bucket, you can use iGame Center for lighting synchronization, the look and feel is very cool.

Of course, it should be noted that because the iGame GeForce RTX 4080 Water God itself has to occupy a 360cold row, we should pay attention to the chassis compatibility when configuring CPU heat dissipation. Most conventional size ATX chassis cannot hold two 360cold rows.

On the side of the graphics card body, in addition to the 3*DP 1.4a + 1*HDMI 2.1s, there is also an one-button overclocking button unique to the Seven Rainbow. The iGame GeForce RTX 4080 Aquarius can unlock the higher TGP when pressed, resulting in a more aggressive performance release.

The default TGP power consumption of GeForce RTX 4080 is 320W, while iGame GeForce RTX 4080 can consume up to 380W / 470W after one button overclocking due to its strong heat dissipation. This performance release is definitely the ceiling of RTX 4080.

In order to carry higher power consumption, the power supply interface has also changed from 3 8Pin to 16Pin in the public edition to 4 8Pin to 16Pin in the same model as RTX 4090. Therefore, the demand for power supply is even greater, and a full power supply of more than 850W is recommended.

Technical analysis: energy efficiency ratio into overclocking potential our hands of iGame GeForce RTX 4080 Aquarius is based on the current positioning of the second highest AD103 core, there are 7 groups of GPC, of which 4 groups are full of blood. There are 9728 CUDA cores, 304 Tensor cores and 112 ROP units inside, which is similar to that of the previous generation RTX 3090.

The default core frequency of iGame GeForce RTX 4080 Water God is 2205MHz-2505MHz. When one-button overclocking is enabled, the highest frequency will be pulled 150MHz by default and come to 2205MHz-2640MH. This promotion is not insignificant. Video memory is achieved in one step to the 256-bit bit width of 16GB GDDR6X. The large-scale improvement of video memory makes 4K games no longer worry about exploding memory, while also taking into account the current popular AI productivity work.

The architecture of the iGame GeForce RTX 4080 Water God is also the latest NVIDIA Ada architecture, which is based on the TSMC 4N NVIDIA custom process, thus achieving a leap of up to 2x performance and power consumption. The throughput of streaming multiprocessors is twice as high as that of the previous generation. The effective ray tracing computing power of the third generation RT Cores is 2.8 times higher than 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.

As for the concrete function, 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: the potential for overclocking is huge. When you come to challenge us, we mentioned that iGame GeForce RTX 4080 Water God has an one-button overclocking function, so we do it directly in one-button overclocking mode in the actual test. First of all, the single-baked doughnut, after 15 minutes, the core temperature is stable at 54.8 ℃ and the power consumption is about 375W, which accords with the calibration after overclocking. I have to say that the temperature of 54.8 is so low that the core is about to catch a cold. The most important thing is that the fan is far from fully loaded, only running more than 30%, so there is almost no noise to use.

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 measured score of iGame GeForce RTX 4080 Water God is 99.5%, and the performance release is extremely stable.

In the 3DMark TimeSpy DX12 test, the score of iGame GeForce RTX 4080 Water God card reached 27352. For comparison, the scores of public version RTX 4080, GeForce RTX 3080 10G version, RTX 3090 and RTX 3090 Ti were 26552, 17306, 18981 and 21862 respectively. In other words, the iGame GeForce RTX 4080 Water God has surpassed all the graphics cards of the previous generation RTX 30 series, and has increased by 50% compared with the previous generation of RTX 3080 of the same level.

In the 3DMark Fire Strike DX11 test, the score of iGame GeForce RTX 4080 Water God card reached 55838. For comparison, the scores of public version RTX 4080, GeForce RTX 3080 10G version, GeForce RTX 3090 and GeForce RTX 3090 Ti were 53379, 40932, 46045 and 52630 respectively. This score is more obvious than the improvement of the public edition.

In the 3DMark Portal Royal light pursuit test, the iGame GeForce RTX 4080 Water God scored 17714 points, which is greater than the performance of the grating. It is also about 50% higher than GeForce RTX 3080.

The score of iGame GeForce RTX 4080 in theoretical running is the highest of all the RTX 4080 tested by the author. We have made a comparison table of GPU physical scores. In all projects, iGame GeForce RTX 4080 has a significant improvement compared with the public card.

Of course, if you buy such a water-cooled card, it will be a waste not to overclock. Due to the shortage of time, the author will not debug its voltage in detail this time, so we will use the overclocking control of iGame Center to simply pull the frequency under the default voltage.

The measured frequency can not pass through the baking machine, so we choose the core frequency to pull 200MHz, the video memory frequency to pull 600MHz, and the voltage and power consumption to pull 20%. At this time, the frequency reached 2840MHz, compared with the public domain frequency increased 330MHz, this overclocking ability is not strong.

After the measured manual overclocking, the video card score is further increased to 28402 points. Compared with one-click overclocking, it has increased by 3.7%, and the silent frequency has increased by 6.5% compared with the public edition. It can be said that iGame GeForce RTX 4080 Water God non-public graphics card in the ceiling.

DLSS 3 details: AI power games, 4 times the number of frames skyrocketed although the theoretical performance has exceeded all RTX 4080, but the really big improvement is DLSS 3 technology. DLSS 3 is a performance multiplier driven by AI, 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 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 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.

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!

Next two, let's move on to the testing of DLSS 3. The latest version of 3DMark has been adapted to DLSS 3's BenchMark, and we can directly see the difference between the test results of iGame GeForce RTX 4080 and the control variables of DLSS 2. Measured in DLSS 2 mode, the average number of frames is 100.65 frames, which is nearly 2 times higher than that without DLSS 2.

But if we turn on the latest DLSS 3 technology, the number of frames on the iGame GeForce RTX 4080 Pluto card goes straight to an average of 129.29 frames, a significant increase compared to the number of frames without DLSS. It is also important to note that the higher the number of frames in DLSS 3, the more frames you can insert. Therefore, it is recommended to use DLSS 2 to exceed the number of frames to a smooth level, and then use DLSS 3 to break the performance limit.

Only a month later, DLSS 3 has been adapted to a number of new games, and when GeForce RTX 4080 is released on November 15, 10 DLSS 3 games will be released:

1. The Legend of the Plague: Requiem (A Plague Tale: Requiem)

2. "memory of Light: infinite" (Bright Memory: Infinite)

3. "destroy all mankind 2: re-detect" (Destroy All Humans! 2-Reprobed)

4. "Shadow Torch City" (F.I.S.T.: Forged in Shadow Torch)

5. F1 ®22

6. "against the cold" (Justice)

7. "reincarnation of Life and death" (Loopmancer)

8. Marvel Spider-Man: remaking (Marvel's Spider-Man Remastered)

9. Microsoft simulated Flight (Microsoft Flight Simulator)

10. "Super Breakthrough" (SUPER PEOPLE)

As long as it adapts to DLSS 3, it can be downwards compatible with DLSS 2, and the development difficulty is very low, so it is certain that more and more developers will join the DLSS camp. We selected a number of games that have been adapted to DLSS 3, such as Cyberpunk 2077, Legend of the Plague: Requiem, Breakthrough, destruction of all Mankind 2: re-Exploration and the Tower of Fantasy to test the water god of RTX 4080.

Let's first test the most stressful "Cyber punk 2077" and run its own BenchMark under the 4K highest picture quality super light, and get the following data. As you can see, when the DLSS 3 option is all on, you can increase the number of frames by up to 80%. Compared with the DLSS 2 in the same gear, the number of frames has increased by more than 30 frames, which is quite significant. In the actual game, driving to the DLSS 3 balance gear can already play quite smoothly.

So will DLSS 3 have a serious impact on picture quality? When we compare the pictures with NVIDIA ICAT tool, we can see that the aliasing on the left is indeed a little more, but it is not obvious macroscopically, it can be said that DLSS 3 technology really allows us to "pick up" a lot of frames for nothing.

↑ left DLSS balanced, right DLSS off

In a newly launched 3A sequel, the Legend of the Plague: Requiem, the effect of increasing the number of frames is even more obvious. By default, it can not reach 60 frames, but with the blessing of DLSS technology, the number of frames can be doubled only by driving to the balance file. If DLSS 3 + super performance is turned on, the number of frames can even be increased by more than three times.

"PUBG" developer Blue Hole's new book "Super Breakthrough" also offers options with DLSS 3. As can be seen from the following data, although there is still a little problem with adaptation, and the performance file is lower than the balanced file certificate, the frame rate has actually doubled after all the DLSS options are enabled.

Then there is a nonsensical American game "destroy all humanity 2: re-explore". In terms of frame number performance, DLSS 3 can also increase the frame number by more than 50%, and the higher the frame number, the more obvious the effect on DLSS.

Next, the author tests the "magic tower". The author once thought that "Magic Tower" is just a mobile game, but the picture quality of the PC end is so excellent. It provides complete support for RTX+DLSS 2+DLSS 3 technology. After turning on RTX, the reflection of the ground is obviously more real, and the feeling of the cyber city is lifelike.

Of course, this light pursuit effect is also very performance, with only more than 40 frames under the highest picture quality of 4K. But we can turn on DLSS 3 technology, achieve 3-4 times the number of frames, we can achieve 4K light chase fun.

So 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. Let's take "Super Breakthrough" as an example, the delay after turning on DLSS 3 is lower than opening nothing at all.

Game measurement: enjoy 4K e-sports, higher frame number and lower delay in addition to supporting DLSS 3 masterpiece, CTOnews.com has also tested several mainstream games for everyone. IGame GeForce RTX 4080 Aquarius will be tested with the highest resolution of 4K this time. In the newly launched "Watch Pioneer" and "return", it provides NVIDIA Reflex low latency option, which enables CPU to submit rendering work to GPU before the completion of the previous frame, thus greatly reducing or even eliminating the rendering queue, which makes the response time faster and aiming accuracy higher. After the enhanced ReFlex is turned on, the delay is reduced by half.

In Tomb Raider: shadow, it is measured that even if DLSS is not turned on at the highest resolution of 4K, it can run up to 140frames while running BenchMark, which is basically enough for 4K144Hz monitors to play.

The game is also supported by DLSS 2, which can increase the number of frames by up to nearly 90% after turning on DLSS 2. All the projects are also slightly higher than the public domain, and can already challenge the future 8K games.

Finally, we tested a light chase 3A masterpiece "Control". With the highest picture quality and the highest light in 4K, DLSS can hardly play smoothly, while iGame GeForce RTX 4080 almost doubled the number of frames after opening the initial DLSS, which is an excellent experience.

Creative production: long-time rendering can also keep quiet. IGame GeForce RTX 4080 Water God's arithmetic power has been greatly improved, and the visual memory has also improved a lot, so it has been given a certain productivity attribute. There will be some achievements in dealing with creative production and deep learning. At the same time, iGame GeForce RTX 4080 Water God can also install NVIDIA Studio driver, and more than 75 creative applications can call the AI computing power of NVIDIA CUDA core to greatly improve work efficiency.

In modeling and rendering software, iGame GeForce RTX 4080 Water God 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, iGame GeForce RTX 4080 Aquarius scored 3138 points, which can successfully cope with most of the modeling rendering requirements.

Thanks to the improved performance of light pursuit, the score of iGame GeForce RTX 4080 Aquarius in V-Ray GPU RTX has also increased to 4250, which is enough to cope with high-pressure 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. According to the final test results of iGame GeForce RTX 4080, its rendering ability is equivalent to more than 10 GTX 980s working at the same time, and the improvement of computing power from GTX 980s to RTX 4080 is like a lifetime away.

In the later part of the video, the iGame GeForce RTX 4080 Water God is also equipped with the eighth generation NVIDIA NVENC encoder, which supports 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 and clip Pro also provide support for AV1 coding. As a free and open source coding, AV1 will certainly be the mainstream coding in the future.

Why is AV1 favored by manufacturers? Because it can greatly reduce the video volume on the basis of maintaining the picture quality. Let's do a test here. Simultaneously suppress the 20000Kbps video of two 4K30 frames, one using H.264 coding and the other using AV1 coding. Results the size of H264 version is 361mbJ AV1 version only 280mb, and the size is reduced by 28%.

So will there be any damage to the picture quality? We select a picture in the video and use the NVIDIA iCAT tool to look at the details. As a result, there is almost no difference between the image quality on the left and that on the right. Small and high-definition, no wonder AV1 will become the next generation of industry norms.

CTOnews.com also 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 GeForce RTX 4080 Water God can reach 2670, which is the highest among the 4080 tested by the author.

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. For anchors who want to buy a high-end graphics card, with the efficient coding of NVIDIA Broadcast+AV1, full-link LVB can be completed with only one machine.

The author believes that this integrated water-cooled graphics card is particularly suitable for creative production. Because creative producers are often particularly sensitive to noise. The water-cooled design means that its noise has a natural advantage over air-cooled graphics cards.

Summary: at the top of RTX 4080, the author tested a large number of RTX 4080 graphics cards this week, but the brightest one is the Seven Rainbow iGame GeForce RTX 4080 16GB Neptune OC. It is the most powerful of all 4080 and the most unique of all RTX 4080. These two points alone are enough to arouse the desire of high-end players to buy.

If you are a performance-oriented 4K gamer, or want to play with extreme fans of overclocking, then Seven Rainbow iGame GeForce RTX 4080 16GB Neptune OC will be your unique choice. At present, Seven Rainbow iGame GeForce RTX 4080 16GB Neptune OC has been listed, if you are interested, you can check it out.
