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

In the previous evaluation of the RTX 4070Ti graphics card, we mentioned that it is suitable for the ultimate gaming experience at 2K resolution. Now that RTX 4070 has been officially released, how does it compare to the actual gaming experience of RTX 4070Ti? This time, let's take the gigabyte AORUS GeForce RTX 4070 MASTER 12G graphics card as an example to see the performance of RTX 4070.

Gigabyte RTX 4070 Super carving belongs to a relatively stacked card, the overall card body is dark gray, so we matched the black chassis this time to make it look more e-sports attributes. In this test, CTOnews.com will be used as a test platform with the following hardware to ensure that there are no performance bottlenecks during the test.

I wonder if you have noticed that this time we adopted gigabyte UD 1000GM, a kilowatt power supply based on ATX 3.0specification released by gigabyte last year. The biggest highlight of this graphics card is its own 12VHPWR power supply line, which supports up to 600W power supply, so that high-end graphics card devices such as RTX3090Ti no longer need to use 12VHPWR to 8Pin*3 wiring, reducing the difficulty of installation and wiring, but also reducing the risk of computer failure. It can be said to kill more than one stone. I hope other power manufacturers can follow up as soon as possible.

Design gigabyte RTX 4070 Super carving is a three-slot three-fan graphics card, so it is not a big problem for the mainstream ATX chassis to fit into it. The overall shape is very strong, and the whole card body is wrapped in silver-gray metal armor.

In the front part of the graphics card, gigabyte adopted two major designs this time, namely, the RGB dazzling color wheel and the wind power heat dissipation system. The so-called dazzling halo wheel means that gigabyte designs a three-ring lighting effect on the metal enclosure edges of three newly designed 108mm bionic shark fans. The fan body does not glow after lighting, but the halo part will show a tricolor RGB gradient mixed light.

Of course, you can set up up to 12 different RGB effects in gigabyte's light effect adjustment software, and also support custom exclusive colors. At the same time, there is an uppercase AORUS decorative lamp supporting RGB backlight on the side and back of the graphics card to ensure that users can have an eye-catching RGB effect no matter whether they are vertical or horizontal.

The wind power heat dissipation system refers to the heat dissipation design of the entire graphics card, such as three fans supporting 3D start and stop, positive reversal design, internal heat equalizing plate direct contact with GPU,9 root composite heat pipe, and so on.

Gigabyte on one side of the graphics card also provides a dual BIOS mode switch to facilitate users to quickly switch performance mode, do not need strong performance but the pursuit of quiet can be put into mute mode to reduce noise, mode switching needs to restart the computer to take effect, the factory default is full of blood OC performance mode.

The backplane of the video card is also made of metal, and the intake grille occupying half of the area on the right can quickly discharge heat from the video card, improve the heat dissipation efficiency and make the performance stability of the video card higher.

This time, a custom graphics card bracket based on the size and shape of the video card is included in the package, which can give better support to the card body during installation to avoid bending the motherboard or the resulting deformation problems.

In terms of interface, gigabyte RTX 4070 super carving is consistent with the public version, which is the latest 16pin power supply interface, and the package also comes with a 2*8Pin-to-16Pin conversion head and carved head sticker.

Core parsing the core of ‏ RTX 4070 is built by ‏‏ based on AD10 ‏‏ 4 core like RTX 4070Ti. 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 ‏‏ of ‏‏ department in ‏‏. In addition, NVENC video encoding unit is one less than 4070Ti, and NVDEC video decoding unit is still retained.

Gigabyte RTX 4070 super carved ‏‏ core frequency is 1920MHz, ‏‏ 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. 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 next we carry on the theoretical performance test. First of all, ‏‏ is double-baked. After 15 minutes, the core temperature is stable at around ‏‏ 71 ‏‏℃ and the power consumption is about 187 ‏‏ W. The power consumption of ‏‏ is well controlled, and the fan only works at 65% at this time, so the noise control is very good, and the game is very quiet.

‏ 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 gigabyte RTX 4070 super carving ‏‏ is 99.6%, and the performance release is excellent.

In the 3DMark TimeSpy DX12 test, the graphics card score ‏‏ is almost the same as the 18793 score of RTX 3080 12GB, and the silent frequency score ‏‏ is 18880, compared with 20501 for RTX 3090. ‏‏ can see that the DX12 score of gigabyte RTX 4070 Super Eagle has been at the same level as RTX3080 12G after the driver update.

In the 3DMark FireStrike DX11 test, ‏‏ can no longer meet the needs of high-end graphics cards because the traditional FireStrike can no longer meet the needs of high-end graphics cards, so we only tested the more stressful FireStrike Extreme. Gigabyte RTX 4070 super carved graphics card score reached ‏‏ 21599, as a comparison, the GeForce RTX3080 12G score was ‏‏ 22781 ‏‏.

And ‏‏ in the 3DMark Portal Royal light pursuit test, gigabyte RTX 4070 super sculpture ‏‏ 11579 ‏‏ score, ‏‏ and RTX 3080 12GB score of 12157, may be the disadvantage of video memory size and memory bit width brought about by the light pursuit performance gap, resulting in running points slightly lower than RTX 3080 12G several hundred points. 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, e-sports game, we selected "CS:GO" this mainstream FPS game to test. When running the BenchMark included in CS:GO, the average frame reaches 489 frames, which can meet the needs of e-sports display for high-frame play.

It is worth mentioning that at present, eight of the top 10 competitive shooting games support NVIDIA Reflex, including "Apex Hero", "call of Duty: theater 2", "Destiny 2", "Escape from Takov", "Fortnite", "Watchman: return", "Rainbow 6: siege" and "Dauntless contract". Opening NVIDIA Reflex can help players ensure high picture quality and high frame rate at the same time. 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 Tomb Raider: shadow, the gigabyte RTX 4070 super sculpture can run to an average of 176frames at the highest resolution of 2K, while RTX 3070Ti can run to 142frames for comparison; and when the DLSS2 quality file is opened, the frame count is further increased to 208frames, and for comparison RTX 3070Ti can run to 165frames.

In "Wild Dart 2: redemption", the average frame with the highest 2K resolution is 108. as a contrast, the RTX 3070Ti can run to 90 frames; when the DLSS quality file is turned on, it can also run at an average of 122frames at the highest 2K quality; as a contrast, RTX 3070Ti can run to 90 frames, so it is not a problem to play smoothly.

These frames are all implemented on the basis of DLSS2, but the most attractive thing about RTX40 series graphics cards 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.

Let's first take a look at the most configured representative game ‏‏ "Cyberpunk: 2077" ‏‏. ‏‏ runs its own BenchMark ‏‏ under the highest quality super light of ‏‏ 2 ‏‏ K. you can see that 60 frames cannot be stabilized by default. If you turn on the DLSS2 of the quality file, you can reach the free play line of 60 + frames. If the DLSS3 option is fully turned on, you can increase the number of frames by up to 3 times. Compared with the DLSS 2 in the same gear, the number of frames has been increased by 35 frames, which is not small.

"Wizard 3" as a very classic old 3A, since the recent update of the next generation version, the configuration requirements have been greatly improved, fortunately, it provides the support of DLSS 3 technology, although it still can not run smoothly at 60 frames by default, but after opening the DLSS2 quality file, the average number of frames of 57 frames finally touched the edge of 60 frames, so it should not be a problem to reduce the image quality a little bit. When DLSS3 is turned on at the same time, the average performance of 88 frames is stress-free.

Finally, let's test a next-generation 3A masterpiece with excellent picture quality, the Legend of the Plague: the Requiem, which is well optimized and supports DLSS 3 technology in its debut.

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.

Finally, we also counted the actual power consumption performance of several games, and we can see that the actual power consumption of the best Wild Dart 2 is only 177W, and the power consumption of all games is less than 200W, which is already lower than that of RTX 3070Ti. Of course, this is inseparable from the SM multi-unit stream processor in the new ADA architecture, which can not only improve the performance by two times, but also reduce the power consumption. So the fit of RTX 4070 for 2K games is not only about performance, but also about power consumption.

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. Gigabyte RTX 4070 Super Eagle 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 ‏‏, gigabyte RTX 4070 Super Eagle scored 1874 points, making it easy to cope with most modeling rendering needs. ‏

Similarly, there is no problem with RayTracing modeling and rendering. ‏‏, such as the gigabyte RTX 4070 Super Sculpture ‏, has a score of 2639 ‏‏ in V-Ray GPU RTX. ‏

In the BenchMark that comes with the commonly used renderer tool Octane, the rendering ability of RTX 4070 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 mainstream modeling software Blender, gigabyte RTX 4070 super sculpture performs well, and the specific score is shown in the figure, so it is not a problem to cope with some complex modeling work.

In the later part of the video, the gigabyte RTX 4070 Super Encoder 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. At the same time, AI computing power can also intelligently sharpen and strengthen the characteristics and edges of objects and characters, of course, it needs to occupy a certain amount of GPU resources for computing, so it is best not to play 3A games with high graphics card occupation when watching video with this technology.

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. The final score is 1565, which can easily cope with complex video clips of 4K or even 8K.

In the special effects production software Adobe After Effects, we also use PugetBenchmark for testing. The final score is 1655, which shows that the creative production performance of RTX 4070 is very excellent.

After summing up after various tests, in fact, we already have a certain understanding of the performance of this card. Compared with the previously released RTX 4070 Ti,RTX 4070, the positioning of 2K games is more inclined to the smooth performance of 2K games. With the blessing of NVIDIA DLSS 3 technology, many games with native 2K resolution can run to a higher number of game frames, ensuring the player experience while still having excellent performance-to-price ratio.

As for the graphics card itself, gigabyte RTX 4070 super carving this card design not only inherited a lot of "carved card" design of the classic elements, the overall style is also more fashionable cool, in the use of RGB lighting effect is not exaggerated but the atmosphere to give the right sense, if not put it up to install it is a pity, in short, if you need a graphics card that can meet your 2K game performance, gigabyte RTX 4070 super carving will not let you down.
