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

After the launch of the RTX 40 series of high-end cards, strong performance and ultra-low power consumption have been recognized. But the price is also relatively high. Since the release of RTX 4070, more and more people-friendly graphics cards will also be available to us. One of the starters is the Seven Rainbow iGame GeForce RTX 4070 Ultra W V2.

CTOnews.com also received Seven Rainbow iGame GeForce RTX 4070 Ultra W V2 in advance. In this test, we will use a set of high-end intel configuration to test to avoid graphics card bottlenecks as much as possible. The specific configuration is as follows:

The design of the Seven Rainbow iGame GeForce RTX 4070 Ultra W V2 basically follows the previous cooling module of the Seven Rainbow iGame GeForce RTX 4070 Ti Ultra W OC, and the performance release will be more easy. Is still a standard 3-slot large graphics card, BWH size for 337*150*60mm, the overall design is compact. In the past, the iGame Ultra W series of Seven Rainbow has always been dominated by white. And the area of this painting has greatly increased, the overall perception presents a pop cartoon style, a sense of fashion arises spontaneously.

The iGame GeForce RTX 4070 Ultra W V2 graphics card features a three-fan design, each consisting of nine white annular blades dotted with a blue-and-white Logo. The graphics card is surrounded by a metal edge, highlighting its tough appearance style. This graphics card is equipped with a luxurious heat dissipation module, which can easily cope with the cooling needs of only 200W RTX 4070 graphics cards.

The back panel of the iGame GeForce RTX 4070 Ultra W V2 graphics card is white, decorated with pink Ultra Logo and dazzling in color.

The right back plate has a hollowed-out design to facilitate the cooling air blowing through the fins to enhance the heat dissipation performance.

The periphery of the graphics card is surrounded by a white edge with an eye-catching GeForce RTX logo printed on the top. The RGB lighting area on the right side of the video card uses silver mirror treatment and white comic special effects, showing a fashion sense that belongs to young people from the side-transparent chassis.

Seen from the side, under the outer frame is a dense heat dissipation grille, this heat dissipation system is really quite luxurious.

In terms of power supply, it uses the 16Pin power supply interface of the latest ATX3.0 specification, and comes with the adapter from 2*8Pin to 16Pin in the package. in fact, its TGP power consumption is only about 200W, which can be driven by a single 8Pin power supply in theory. When we install the machine, it is best to use a power supply that supports the ATX 3.0 specification, which can make the chassis more beautiful. If you have to use an adapter, you can use an one-minute and two-8Pin cable.

The I / O interface bezel uses dark gray color matching, and the interface is equipped with 3*DP1.4a interface and 1*HDMI2.1 interface, and the highest 8K60Hz output is supported. The bezel also provides an iGame switch BIOS button of the Seven Rainbow signboard, which can be switched by pressing.

Core parsing RTX 4070 is similar to RTX 4070Ti, both are based on the AD104 core, but the details are different. The specific core code is AD104-250. There are 4 groups of blood-filled GPC, with 5888 CUDA cores, 184Tensor cores, 46 third-generation RT cores and 64 ROP units, which can basically be understood as retaining 80 per cent of the core size of RTX 4070 Ti. However, the signature NVENC unit has changed from two to one, which means that its video codec capability is weaker than that of RTX 4070 Ti.

The BOOST frequency of RTX 4070 is 2475MHz, and the default frequency is 1920MHz. Video memory is consistent with RTX 4070 Ti. All are 12GB GDDR6X with 192-bit bit width, and the bandwidth is also 21Gbps. From the above positioning, we can see that RTX 4070, like RTX 4070 Ti, is a medium-and high-end graphics card for positioning 2K high frame rate games.

Of course, GeForce RTX 4070 still uses the latest NVIDIA Ada architecture, based on TSMC 4N NVIDIA custom process, thus achieving a leap in performance and power consumption of up to 2x. Its streaming multiprocessor throughput is more than twice that of the previous generation, and the ray-tracing computing power of the third-generation RT Cores is 2.8 times higher. In addition, the fourth generation of Tensor Cores added a FP8 engine with up to 1.32 petaflops of Tensor processing performance, more than five times that of the previous generation. SER technology brings up to three times the performance improvement for ray tracing, and up to 25% improvement for overall game performance.

The new Ada architecture brings many new features in specific functions: the introduction of an optical flow accelerator enables DLSS 3 to predict the motion changes between frames in the scene, thus realizing the AI frame insertion technology, improving the frame rate while maintaining the image quality. In addition, the new architecture also supports the application of dual AV1 encoders, which shortens the video export time and achieves better picture quality. At the same time, the application of RTX VSR function also makes real-time video super-resolution possible.

Theoretical performance the power consumption of RTX 4070 will be very low, which has been heard before. How low can it be? Next, we carry on the theoretical performance test. First of all, it is a single-baked doughnut. After 15 minutes, the core temperature is stable at 62.4 ℃, and the apparent storage temperature is only 75.8 ℃. The power consumption of the whole card is only 200W, it has to be said that this power consumption is really very low, if the power supply is not false, CPU is equipped with i5, R5 and other 100W CPU, as long as 450W power supply can drive the whole machine. Most importantly, it only needs a single 8Pin 1 / 2 output line to work properly, which means that players with upgrade ideas do not need to change the power supply at all.

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 Seven Rainbow iGame GeForce RTX 4070 Ultra W V2 is 99.8%, the performance release is extremely stable, and the fan noise is very low.

In the 3DMark TimeSpy DX12 test, the score of the video card reached 18594, which has exceeded the RTX 3080 10G and is basically the same as the RTX 3080 12G. It can be said that the DX12 physical performance of RTX 4070 is about the same as the high-end graphics card of the RTX 30 series.

In the 3DMark FireStrike DX11 test, because the traditional FireStrike can no longer meet the needs of high-end graphics cards, we only tested the more stressful FireStrike Extreme. The score of the Seven Rainbow iGame GeForce RTX 4070 Ultra W V2 graphics card reached 22053 points, which was also similar to that of RTX 3080 12G, while the power consumption was much lower.

In the 3DMark Portal Royal light pursuit test, Seven Rainbow iGame GeForce RTX 4070 Ultra W V2 scored 11418, indicating that its light pursuit ability is between RTX 3080 10G and RTX 3080 12G, which is enough to meet the needs of 2K light pursuit games.

From the above performance tests, the iGame GeForce RTX 4070 Ultra W V2 positioning is a 2K game graphics card. So next, we will carry out the actual measurement of the game, the resolution is adjusted to 2560 to 1440, and the picture quality is adjusted to the highest. The first is the competitive game "CS:GO", which shows the performance of RTX 4070 in high frames. After running the built-in BenchMark, the average frame reaches 480 frames, which can meet the needs of 2K high frame play, and can run all kinds of electronic competition screens. It is worth mentioning that eight of the ten major competitive shooting games now support NVIDIA Reflex, including "Apex Hero", "call of Duty: theater 2", "Destiny 2", "Escape from Takov", "Fortnite", "Watch Vanguard", "return", "Rainbow 6: siege" and "Dauntless contract". NVIDIA Reflex can reduce operational delays, improve response speed, and make guns more sensitive.

Next, the author also tested the performance of iGame GeForce RTX 4070 Ultra W V2 at 2K resolution in Wild Dart 2: redemption. Without turning on DLSS, iGame GeForce RTX 4070 Ultra W V2 has been able to play more than 2K 100 frames, which is undoubtedly an excellent experience.

If we turn on the DLSS of the quality file, the number of frames will be further increased to an average of 121frames, and there is almost no loss of image quality at this time, and the experience is excellent.

We got a similar answer in another classic 3A masterpiece, Tomb Raider: shadow. Running the built-in BenchMark at the highest 2K picture quality has reached an average of 184frames, satisfying the playfulness of the 2K 165Hz screen.

When DLSS is turned on, the frame number is better, reaching an average of 210frames, and the frame number is increased by more than 30 frames. Generally speaking, the performance of RTX 4070 in traditional 3A masterpieces is very close to that of RTX 3080. Surpassing RTX 3070 Ti, RTX 3070 and RTX 2070 SUPER is even easier.

These are just appetizers, and the most attractive thing about the RTX 40 series GPU is its DLSS 3 technology, which further improves the frame rate. DLSS 3 is a performance multiplier driven by AI, powered by the new fourth generation Tensor Core and GeForce RTX 40 series GPU optical flow accelerator, is the latest version of NVIDIA's acclaimed deep learning supersampling technology, while providing groundbreaking optical multi-frame generation, will open a new era for NVIDIA RTX neural network rendering games and applications.

To put it simply, the past DLSS 2 technology improved image quality and frame rate by rendering a low-resolution image and then zooming in to a high resolution through AI. On the basis of compatibility with DLSS 2, the new DLSS 3 technology adds a frame generation function, which can insert a new frame calculated by AI between two real frames, so as to double the frame rate. At the same time, 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 far, more than 280 DLSS games and apps have been released. There are a total of 30 released DLSS 3 games. In terms of the progress of the release, DLSS 3 was adopted seven times faster than DLSS 2 in the first six months of the release of DLSS 2 and DLSS 3 respectively. It seems that the difficulty of adaptation is quite low. I believe that more and more games will adapt to DLSS technology in the future.

Let's first take a look at the frame number of the most stressful "cyber punk 2077" at 2K resolution. By default, RTX 4070 still has no way to play, with an average of about 38 frames. If DLSS 2 quality is turned on, the average number of frames can reach 69 frames. If you open the exclusive cool techs DLSS 3 of the RTX 40 series, it will soar to an average of 105 frames, meeting the demand for 2K high frames to play, even 4K.

Legendary 3A masterpiece "Wizard 3" has also recently updated the next-generation version, which greatly improves the configuration requirements, but also provides support for DLSS 3 technology, which is undoubtedly good news for RTX 40 series graphics cards.

Since they are all games developed by Polish Donkey, they are also very similar in terms of frame number. When DLSS is not enabled at 2K resolution, the average iGame GeForce RTX 4070 Ultra W V2 is only 39 frames, but only with DLSS 3 in quality file, the number of frames can soar to an average of 88 frames, so you can have fun.

In another next-generation 3A masterpiece, the Legend of the Plague: Requiem, the optimization is relatively much better. Even if you do not open any AI tools, you can play smoothly, and after the addition of DLSS 3, you can double the number of frames and play easily.

When iGame GeForce RTX 4070 Ultra W V2 has a 2K resolution and does not turn on DLSS 2, it will be able to play at 68 frames. If you turn on the DLSS 2 quality file, you can achieve an average of 87 frames, and if you turn on DLSS 3 inserting frames, the number of frames will soar to an average of 135frames, meeting the needs of 2K high-brush displays.

By the way, the author also replaced this configuration with RTX 3070 Ti to test a set of data to see how much performance will improve between generations and how much will be improved with the blessing of DLSS 3 technology. The performance of the measured frame number is quite gratifying. With DLSS 3 off, RTX 4070 has a frame count advantage of about 10%. If you turn on the DLSS 3 technology exclusive to the RTX 4070 series, the number of frames will almost increase by 2-2.5 times, which is a qualitative gap with the RTX 3070 Ti.

As we mentioned earlier, the power consumption of RTX 4070 is quite low, which can actually be driven by a single 8Pin power supply. So we also use Nvidia's official FrameView tool to count the average power consumption in each 3A masterpiece. It can be seen that the actual power consumption of iGame GeForce RTX 4070 Ultra W V2 in most 3A masterpieces is about 180W-190W, which can be said to be quite high. As an ITX small host enthusiast, the author has begun to rub hands.

The creative production iGame GeForce RTX 4070 Ultra W V2 has 12 gigabytes of large graphics memory, which is exactly the same as the specification of RTX 4070 Ti. As a result, it has also been given a certain degree of creative production capacity, and the iGame GeForce RTX 4070 Ultra W V2 graphics card is equipped with a powerful CUDA core, providing excellent performance for creative production and deep learning. In addition, the graphics card also supports the installation of NVIDIA Studio drivers to accelerate more than 110 of the most popular creative applications. Proprietary SDK makes these applications run faster and provides exclusive features such as Optix, DLSS, and Maxine. NVIDIA Studio has a full range of creative applications, including NVIDIA Omniverse, Broadcast, Canvas and RTX Remix.

In modeling and rendering software, the 5888 CUDA cores of iGame GeForce RTX 4070 Ultra W V2 provide hardware acceleration for increased productivity. Almost all modeling software optimizes NVIDIA's GPU, so it can take into account efficiency, stability and compatibility. For example, in the commonly used rendering tool V-Ray, you can take advantage of the ray tracing feature of RTX acceleration to achieve high-performance final frame rendering. In addition, GPU with AI noise reduction can further accelerate interactive rendering and provide a smoother work experience.

In V-Ray Benchmark, iGame GeForce RTX 4070 Ultra W V2 scored 1873, which can handle most medium-sized modeling rendering needs.

Thanks to the improvement in light pursuit performance, the score of iGame GeForce RTX 4070 Ultra W V2 in V-Ray GPU RTX has also increased to 2662, which can also meet some medium load light pursuit modeling requirements.

In the later part of the video, the iGame GeForce RTX 4070 Ultra W V2 is also equipped with NVENC encoders and NVDEC decoders. This means that its ability to render video clips is also good. And RTX 4070 also supports the next generation video coding technology AV1,AV1, 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 to ensure that its GPU fully supports today's mainstream multimedia applications. At present, the domestic professional version of editing and projection has achieved accelerated support for NVIDIA AV1 video encoders. The commonly used video color editing software DaVinci also provides support for AV1 coding. As the major video platforms want to save the cost of server traffic, AV1 coding will become the mainstream coding method in the future. This means that NVIDIA GPU on iGame GeForce RTX 4070 Ultra W V2 will be able to take full advantage of its AV1 acceleration when handling video editing and rendering tasks in the future, providing more efficient performance and a smoother work experience.

In order to test its video rendering performance, CTOnews.com also tested the PugetBench For Adobe family bucket for everyone. Measured iGame GeForce RTX 4070 Ultra W V2 in the Adobe Premiere commonly used by creative workers, we turn on GPU Cuda acceleration, and then use PugetBenchmark to test. The final score was 1513, not inferior to RTX 4070 Ti.

We also use PugetBenchmark for testing in Adobe Effects, another more stressful video special effects software. The final score is 1629, which shows that the creative production performance is very excellent.

In addition to content production, RTX 4070 also has new features in the area of content consumption. That's RTX VSR technology. The full name is RTX Video Super Resolution (RTX Video Super Resolution Technology). It can improve the definition of online 1080p video to 4K resolution at most through GPU's AI calculation. At present, this technology has been adapted to Chrome browser and Edge browser, and will also be adapted to local players led by VLC.

The use of RTX video super resolution is very simple, as long as the driver of the RTX 30 series / 40 series is updated to version 531.14 and the Chrome / Edge browser is updated to the latest version. Enable the path as follows: NVIDIA Control Panel-Video-adjust video image settings. There are four gears available under this option box. The higher the gear, the more obvious the super-resolution effect, but it will also consume more GPU resources.

At present, it already supports some foreign video platforms (Youtube, Twitch, Netflix, Hulu and Disney+) as well as domestic mainstream video platforms (bilibili, Douyu and Huya). Local video super resolution will also be supported in the future. In the following test, after the resolution of the leftmost native 480p is overscored, the following 1-4 gear can be seen more clearly, and the actual look and feel is comparable to that of 4K.

↑ is 480p, VSR1, VSR2, VSR3, VSR4 from left to right.

To sum up, I have to sigh that Lao Huang is skillful in cutting. The core size of the RTX 4070 is about 15 per cent lower and its price is 15 per cent lower than that of RTX 4070Ti. And with such a knife, it just enters the budget space of many 2K gamers. Coupled with ultra-low power consumption and DLSS 3 technology, many players who use old cards may consider upgrading their graphics cards directly to meet the 2K high-frame playability.

And today's protagonist Seven Rainbow iGame GeForce RTX 4070 Ultra W V2 also shows excellent quality, its design feels young, and its heat dissipation capacity is so much that it is an ideal choice for high-end RTX 4070 graphics cards. It is understood that at 9: 00 p.m. on April 13, Qi Rainbow iGame GeForce RTX 4070 Vulcan / Neptune / Advanced / Ultra / Tomahawk and other series of graphics cards will be officially available for sale on e-commerce platforms such as JD.com, Tmall, Douyin, WeChat, and offline authorized distribution retail channels, starting at 4799 yuan, including the first test of this iGame GeForce RTX 4070 Ulrta W V2.
