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

Recently, a large wave of RTX4070 graphics cards have been released, this time the RTX4070 series is still focused on 2K resolution games, and played the slogan of 2K game frame number of 100 +, and the energy consumption than dividend brought by the Ada architecture is also worth looking forward to. CTOnews.com has already got this ploughing RTX 4070 snow graphics card in the first round, so let's take a look at its performance.

Design ploughing RTX 4070 snow tread evaluation using 40 series relatively rare double-slot design, the whole card thickness is only 40mm, the length is only 315mm, thin thickness and volume, can greatly increase the compatibility with the chassis, but also give other hardware more space.

In the choice of color matching, the previous Gengsheng RTX4070Ti star series used white painting, but this time the name of the snow series is more artistic conception, painting is also more fresh. The pure white cooling armor covers the front of the video card, while the color of the fan is more cold white.

Tengsheng RTX4070 snow tread also printed "snowflake logo" on the transposable part of the three fans, and embellished with silver brushed texture, which not only has the atmosphere of snow, but also has silver reflective texture, it has to be said that the appearance of Tengsheng RTX4070 snow tread is not low in the white graphics card.

This time, Gengsheng uses the third-generation "Wind Snow" radiator design, and three 92mm specially optimized "Wind Blade" fans can effectively increase air flow and reduce noise.

In the interior of the graphics card, Tengsheng is also equipped with a large area heat dissipation fin grille, four 6mm composite heat ducts, which are also designed with nickel plating to enhance oxidation resistance.

The side part of the armor also supports the RGB lighting effect of faith Logo, which also supports lighting synchronization with major mainstream motherboard brands. The back baffle part is also printed with the large letter Logo, keeping the white painting, and the hollowed-out part is designed with irregular oblique cutting.

On the interface, Tengsheng RTX4070 snow treading is equipped with three most mainstream DP1.4a interfaces and one HDMI2.1 interface, which supports 4K / 240Hz or 8K / 60Hz video output.

Core parsing the core of ‏ RTX4070, like RTX4070Ti, is built by ‏‏ based on AD10 ‏‏ 4 core. There are 4 groups of blood-filled GPC in ‏‏. There are 5888 CUDA cores, 184‏‏ Tensor cores, 46 third-generation RT cores and 64 ROP unit ‏‏ in ‏‏ in ‏‏. In addition, NVENC video encoding unit is one less than 4070Ti, and NVDEC video decoding unit is still retained.

The ‏‏ core frequency of RTX4070 is 1920MHz, and the ‏‏ Boost frequency 2495MHz. In the aspect of ‏‏ video memory, the ‏‏ is a 12-‏‏ GB GDDR6X ‏‏ with 192 ‏‏-bit ‏‏ bit width, and the video memory frequency is as high as 21000MHz. From the above positioning, we can see that RTX 4070 is a high-end graphics card for positioning 2K high frame rate games.

RTX 4070 also builds ‏‏ based on the latest NVIDIA Ada architecture, and its ‏‏ is upgraded to ‏‏ TSMC 4N NVIDIA custom process, resulting in a leap in performance and power consumption of up to 2x. The ‏‏ throughput of streaming multiprocessor ‏‏ 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.

Theoretical performance next we carry on the theoretical performance test. After 15 minutes, the core temperature of the ‏‏ is stable at about 63 ‏‏℃ and the power consumption is about 179 ‏‏ watts. The power consumption of ‏‏ is a little lower than the upper limit of 200W full power consumption, and the fan only works at 59% and 61% at this time, so the noise control is very good and the game is quiet.

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.

In the 3DMark TimeSpy DX12 test, the graphics card score of ploughing RTX 4070 treading snow is 18482, slightly lower than the 18793 of RTX 3080 12GB. For comparison, RTX 3090 is 20501 and TimeSpy Extreme is 8746, which is generally normal.

In the three 3DMark Fire Strike tests, the graphics card scores of ploughing RTX 4070 on snow were 43931, 21389 and 10138 respectively, while the Fire Strike Extreme score of GeForce RTX3080 12G was ‏‏ 22781 ‏‏.

In the 3DMark Portal Royal light pursuit test of ‏‏, the score of ‏‏ 11310 was obtained by ploughing RTX 4070 on snow, and the score of ‏‏ RTX3080 12GB was 12157, which was slightly lower than that of RTX3080 12G. However, reflected in the actual game, the gap will not be too big.

Game measurement ‏ next, we will conduct a game test. We will test all games with the highest 2K resolution. If we have DLSS, we will enable the balance file DLSS, and if we have DLSS3, we will test the number of frames before and after opening and closing. First of all, "CS:GO" this mainstream FPS game, we run the BenchMark that comes with the game, and the average frame of the RTX 4070 snow tread reaches 486frame, which is enough to play with the high frame of the e-sports monitor.

It can also have the lowest delay performance, which I will mention in more detail in later reviews.

Then there are two 3A masterpieces, in the classic 3A game Tomb Raider: shadow, Tengsheng RTX 4070 snow tread runs its own benchmark with the highest 2K resolution by default, and the final average frame number is 177points, as a comparison RTX3070Ti can run to 142frames; then open the DLSS2 quality file, when the number of frames is further increased to 209frames, as a comparison RTX3070Ti can run to 165frames.

Of course, all these frames are based on DLSS2, and the most attractive thing about the RTX40 series is DLSS 3 technology. ‏‏ DLSS 3 is a performance multiplier ‏‏ technology ‏‏ driven by AI, driven by the new fourth generation Tensor Core and the new optical flow accelerator of the GeForce RTX40 series GPU, the latest version of NVIDIA's acclaimed deep learning supersampling technology and groundbreaking optical multi-frame generation, which will usher in a new era of NVIDIA RTX neural network rendering games and applications.

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 4 times higher than that without DLSS.

At present, there are 30 games that support DLSS 3 for the first time, and future new games are bound to support DLSS 3 for the first time, and the total number is still increasing monthly. If you include all the games and apps that support DLSS, then the number will come to more than 280 at once.

We also chose three games that support DLSS 3 for testing. the first is the "Cyberpunk: 2077" ‏‏. ‏‏ runs its own benchmark under the highest quality super light of ‏‏ 2 ‏‏ K, which is only about 40 frames by default, barely able to play. When you turn on DLSS 2 quality, you can run smoothly at frame 67. If you turn on DLSS 3 on this basis, the number of frames can be increased to 100, which can give full play to the advantage of high screen brushing.

Since the next-generation version of "Wizard 3: hunting" has been updated, the configuration requirements have gone up at once, of course, the difference between the picture performance and the host is also very obvious, with the blessing of light pursuit, the fun of watching the scenery has been greatly increased. In our actual measurement, by default, we still can't run more than 60 frames. After turning on DLSS 2, the performance is similar to that of cyberpunk, and it can reach more than 60 frames, but under the dual buff of DLSS 3+DLSS 2, it finally comes to the vicinity of 100 frames.

Finally, the screen performance is very good, but the performance of the better "Plague Legend: Requiem", in the 2K highest picture quality even if not open DLSS, can run to 75 frames, it can be said to be very comfortable. Turning on DLSS 2 can reach 100 frames, while turning on DLSS 2 + DLSS 3 at the same time can reach about 150 frames, which can fully feed the 2K / 144Hz high-brush display.

Of course, it is also popular in the circle that ‏‏ DLSS 3 ‏‏ can lead to increased latency and lack of follow-up in playing games. Indeed, the essence of DLSS 3 ‏‏ is that AI generates new frames, and it takes a time to generate frame ‏‏. The improvement of ‏‏ latency has a great impact on competitive games, but the current games that support DLSS 3 are RPG games that do not eat input delay. And when ‏‏ turns on the frame generation function of DLSS 3, NVIDIA Reflex will force it on to minimize the rendering delay caused by the generated frame. ‏‏ We take the Legend of the Plague: Requiem as an example, the delay is only increased by a few milliseconds after opening DLSS 3 + NVIDIA Reflex, which has no effect on the game experience. However, if both DLSS and NVIDIA Reflex are turned off, there will be a significant reduction in latency, but there will also be a large discount on the number of frames and fluency.

Some friends may worry that opening DLSS will have a great impact on the picture quality of the game. For this, we took two screenshots of the game from the next-generation version of "Wizard 3: hunting", which are completely off DLSS state and open DLSS 2+DLSS 3 state at the same time, and then enlarge the two images to compare the details at the same scale, you can see that there is almost no difference after magnification, and the picture quality party can rest assured to open DLSS.

Left: original quality, right: turn on DLSS 2+DLSS 3

As we mentioned earlier, the power consumption of the RTX4070 is less than 200W, which is one of its advantages, so how does the power consumption perform in the actual game? Will it exceed 200 watts? We have also counted the actual power consumption performance of several games, except that the plague legend is exactly 200 watts, all of them are less than 200 watts. Of course, this performance is inseparable from the SM multi-cell stream processor in the new ADA architecture, which can not only improve performance by two times, but also reduce power consumption and kill two birds with one stone.

Creative production ‏ benefits from 12G large graphics memory and powerful CUDA core, RTX 4070 can be used not only for games, but also for creative production. Tengsheng RTX 4070 Snow tread has 5888 powerful CUDA cores and will make some achievements in dealing with creative production and deep learning. At the same time, it ‏‏ ‏‏ can also install ‏‏ NVIDIA Studio driver, ‏‏ has more than 75 creative applications ‏‏ can call ‏‏ NVIDIA CUDA core ‏‏ AI computing power, greatly improving work efficiency.

In the modeling and rendering software, the 5888 ‏‏ CUDA ‏‏ cores of ‏‏ can provide hardware acceleration for ‏‏. 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 ‏‏, Tengsheng RTX 4070 scored 1871 points on snow treads, which can successfully cope with most of the modeling rendering requirements. ‏

Similarly, there is no problem with RayTracing modeling and rendering, and the running score of the GPU RTX project is 2650.

In the BenchMark that comes with the commonly used renderer tool Octane, the rendering ability of RTX4070 is also very strong. In various tests, its rendering ability is almost equal to the arithmetic power of 4 to 9 GTX 980s, and the progress can be said to be obvious.

In the later part of the video, the RTX 4070 ‏‏ 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. ‏

The trend of AV1 is not only the result of technological advances, but also the pain point of the industry's demand for productivity, which is to significantly compress the size of video files while ensuring that the image quality is almost unaffected.

We also conducted a simple test to export the same video material using two different encodings, H264 and AV1, through the professional version of the clipping software. In the end, the file size encoded by H264 is 159MB, while the file size encoded by AV1 is only 127MB, and the size has been reduced by 21%, but there is no difference in image quality.

In addition, Nvidia also introduced RTX video super-resolution technology, known as RTX Video Super Resolution, for RTX30/40 graphics cards. It can improve the definition of online 1080p video to 4K resolution through GPU's AI calculation, and the principle is a bit like the DLSS technology in the game.

In addition to browsers, well-known VLC native players also provide adaptation of RTX VSR technology in the Beta version. Just like a web page, just open it in the driver control panel. When we use a 480p local video to demonstrate, it obviously feels clearer on the right. Later, when you enjoy the local movie, you can also use this technology to further optimize the picture quality.

In the recently popular AI painting (generative AI), RTX 4070 also has a place for World War I. For example, using the v2-1_768-ema-pruned.ckpt model of stable-diffusion, we tried to draw 20 images of old yellow of AI. It took a total of 2 minutes and 18 seconds for RTX 4070.

On the RTX3070Ti side, it takes 2 minutes and 57 seconds, which is quite obvious compared with the speed gap of RTX4070. If you just want to play with AI, RTX4070 is good enough. Of course, if you want complex research, you'd better go to RTX4090 or higher GPU.

In Adobe Premiere Pro, the non-linear editing software most commonly used by creative workers, we turn on GPU CUDA acceleration and then test it with PugetBenchmark. Tengsheng RTX 4070 snow tread score of 1537, this score can easily cope with 4K or even 8K complex video clips.

In the special effects production software Adobe After Effects, we also use PugetBenchmark for testing. The final score was 1421, showing a decent performance.

Summary through the above series of tests, RTX4070 is a positioning 2K resolution 100 + frame game experience in the high-end graphics card, with the help of NVIDIA DLSS 3 and NVIDIA Reflax technology, it can control most of the mainstream 2K resolution 3A games, and the comprehensive performance in terms of productivity is not to be underestimated. In addition, the RTX4070 is also a graphics card with excellent energy consumption, and the power consumption of running 2K games can be controlled within 200W under full load. Tengsheng RTX 4070 snow tread has a 215W low-power power supply demand, combined with Tengsheng's wind and snow cooling system, it has indeed achieved its advertised low-power ultra-mute double blessing.

Tengsheng RTX 4070 snow tread in addition to the above performance and power advantages, but also Tengsheng flag graphics card appearance of a more outstanding one, the thickness of double grooves so that it does not have the slightest sense of thickness, pure white armored painting with "snowflake logo" pattern of the fan logo, not only a degree of recognition, the whole is also simple to see, very small and clear. The most important thing is that in the price range of 4799 yuan, there are few choices for all-white painted graphics cards. If you want to set up a white sea view room console and have a heavy demand for 2K games, Tengsheng RTX 4070 snow tread is a good choice.
