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

We have previously tested Intel's latest independent graphics card products, the Reid A770 and A750, and shortly after the release of the new product, Intel graphics card's first core partner, Blue halberd, also launched their non-public version of the dazzling high-end series GPU: the Blue halberd A770 flux series. Not only has stronger heat dissipation and stronger performance, the price is lower than the public version.

CTOnews.com also received the blue halberd A770 graphics card in advance. From the packaging, we can see the intention of the blue halberd, they do not blindly pursue big, but strive to be delicate, small and easy to accept. The electrostatic bag which is easy to be consumed and damaged is replaced by anti-static EVA. In addition, lined paper and Chaochao tag-type instructions are added to make it more beautiful and younger.

In this article, we will conduct a detailed test to see how the experience of this non-public product is more cost-effective. The following is the test platform:

The blue halberd A770 is a 2.5-slot thick medium-sized graphics card with an over-the-shoulder design at the top, which is larger than the public version A770 and must have more material for heat dissipation.

Blue halberd dazzle A770 overall design founder, different from the public version, the blue halberd sharp dazzling A770 metal feeling is stronger, the look and feel is more high-end. It is reported that the Blue halberd product designer uses NEO aesthetics in this high-end FLUX film series, following the futuristic aesthetic proposition. He believes that in the process of moving forward to the future, all the usual things will be left behind, as well as the design. Therefore, starting from the extreme practicality, we are committed to establishing a relationship with users that keeps pace with the times and full of vitality, rather than breaking away from users to show the personality of the product.

The radiator is designed with three fans, which is more abundant than the double fans in the public edition. There is a Logo for GUNNIR on the fan.

There have also been some changes in the power supply scheme. The public version is 8Pin + 6Pin, while the non-public version of the Blue halberd A770 is a double 8Pin power supply scheme, which is more affluent than the public version. I believe there will be surprises in the back of the grill. When lit, the upper GUNNIR triangle LOGO will cycle through the glow, looking more smart in the side-through chassis.

The video interface is still standard with 3 DP 2.0 and 1 HDMI 2.0, which can support up to 8K video output.

The interface is the standard PCIe Gen 4.0x16. It is worth mentioning that the motherboard must support and turn on the Resizable BAR function in order to fully release the full performance of the sharp graphics card.

Architecture Analysis Intel Ruixuan A series products are all based on Xe HPG architecture, including a powerful AI engine and enhanced media engine. A new Xe display engine and a new graphics pipeline are introduced to handle a variety of display tasks. Every four Xe cores make up a render slice, and each Xe kernel is equipped with a considerable number of computing units, such as vector engine XVE and matrix engine XMX. In addition, Xe HPG also integrates other mainstream graphics technologies, such as mesh shading, sampler feedback, etc., and its corresponding hardware support can be found in rendering slices.

The most important thing in Intel's Xe HPG architecture is the Xe Vector vector engine, which is to provide a dedicated execution port for floating-point computing (FP). Intel has improved ALU (arithmetic logic unit). This allows the FP instruction to run at the same time as the integer operation (INT) instruction, including the fast INT8 calculation of DP4a.

As for the overall structure of Ruixuan GPU's Xe-core, you can take a look at the following floor plan provided by Intel. Different sharp GPU may vary in the number of computing units, but the general structure is the same.

The basic specifications of the graphics card read by GPU-Z are as follows. The default power consumption of the A770 is 225W, but the power consumption of the Blue halberd A770 is more abundant. If necessary, it can be manually filled in the control panel to get stronger performance, but we will test it at the default power consumption in this article.

Theoretical performance, of course, we are most concerned about the blue halberd dazzling A770 core performance, compared with the public card has how much advantage? CTOnews.com is going to do a stress test. After 10 minutes of the grill, the power consumption is stable at about 209W and the temperature is also at 68 ℃. Not only the power consumption is nearly 20W higher than that of the public edition, but also the temperature is reduced by 5 ℃. It seems that this heat dissipation is very good.

We then run the theoretical score of 3DMark, and then compare it with public cards and graphics cards at the same price. Similar to the results of the roaster, the performance of the blue halberd A770 is slightly higher than that of the public version A770, and the theoretical scores of each item are on a par with RTX 3070. And unlike our previous stereotype of "DX12 is strong, DX11 is short", its traditional DX11 performance is not poor, also surpassing RTX 3070, while the light pursuit performance is similar to RTX 3060Ti.

Based on the outstanding performance of the raster, the Blue halberd A770 also supports XeSS supersampling technology, which is similar to DLSS / FSR. It uses AI for super-resolution and image synthesis to achieve high-performance and high-fidelity vision of the new frequency upgrade technology, up to a two-fold increase in the number of frames. Compared with the game library when we tested A380 before, now Xess's game library is much larger, hope to adapt to more games as soon as possible.

What is the specific effect of Xess? We can borrow the Xess BenchMark provided by 3DMark. From which we can directly see that Xess has greatly improved the number of game frames.

In different gears, the increase in the number of frames brought by XeSS ranges from 50% to 130%, and the effect is quite obvious. And because of the principle of AI scaling, the loss of picture quality is not great. The author's suggestion is to turn on the quality file at 1080p resolution, balance file at 2K resolution, and performance file at 4K resolution.

As can be seen from the above tests, the performance of the Blue halberd A770 is slightly better than that of the public version, and it is far better than the wave of the target RTX 3060 at the press conference.

The game measured so that the blue halberd dazzling A770 will not be a "high score and low energy"? Can you continue the surprise of running points in the game? Will you encounter driver compatibility problems? Let's first test several new games that support XeSS technology, and then compare several popular traditional games. The whole test will be carried out at the highest resolution of 2560 to 1440.

The first is an exploding 3A game "Ghost Line: Tokyo", which can be called a hardware killer. There are only more than 20 frames after light tracking is turned on at 2K resolution, but we can use XeSS technology to render at a lower resolution, and then zoom in to a high resolution to double the number of frames.

We specially selected a scene with strong light. The number of XeSS frames in different gears is measured here, and when the balance gear is turned on at a resolution of 2K, you can achieve free light pursuit of more than 60 frames. It seems that if you want to play 2K light chase masterpieces, you still need this kind of super-resolution technology.

There is also support for ray tracing and Xess technology in another Japanese chess game, the Magic Chronicle. The effect of this kind of top view is not obvious in combat, but it is still very good in skill animation.

In the Chronicle of the Magic Collar, without Xess, you can basically satisfy the fluency of playing 2K60 frames, but when you turn on Xess, you can challenge higher resolution and higher refresh rate, and the game experience has been significantly improved.

This time we are testing an extra street graffiti game "Arcadegeddon". Although the game is low polygonal style, it also provides support for ray tracing and Xess technology.

As a shooting + action game, it needs a higher number of frames to improve the shooting feel. The measured number of frames of Blue halberd A770 is as follows. When Xess is turned on, it can satisfy more than 60 frames of play.

Finally, please run the evergreen tree "Tomb Raider: shadow", this classic 3A is also adapted to Xess technology, it is indeed very rare.

When Xess is not enabled, it is difficult to play 2K fluently, but after turning on Xess, the maximum number of frames can be doubled, and 2K high-frame games can finally be achieved.

It seems that with the help of Xess, the blue halberd dazzling A770 has been able to play 2K in the light pursuit masterpiece. So in traditional games that do not support Xess, can their raster performance stand the test? Let's first test the BenchMark of "CS:GO". The measured number of frames of the blue halberd A770 reaches 262 frames, which is very smooth.

In "PUBG", the average frame number of the blue halberd A770 under the extreme special effects is about 110. it is no problem to have fun and eat chicken in 2K.

Creative production of AV1 coding is an important technology for Intel to bet on. We are familiar with video encoders such as H.264, H.265 and other AVC encoders, but these encoders can no longer adapt to the explosive growth of video. We are in urgent need of a video coding technology with higher compression ratio. AV1 came into being. As a representative of a low-cost and efficient codec scheme, AV1 is 50% higher than the most common H.264 codec and 20% higher than HEVC, so it can provide higher quality images with lower bandwidth and smaller files. And AV1 is a completely open codec without any licensing fees, so it has the advantage of low cost, and its industry prospect is very considerable.

For Intel, Ruixuan GPU has been endowed with a certain attribute of video productivity because it provides hardware support to AV1 in the first place. For example, Davinci and Wanxing Meow Ying, two popular video software, have provided support for the AV1 video coding of the Blue halberd A770.

In addition, the domestic video editing software Wanxing Miaoying also provides support for AV1 coding. When AV1 coding, A770 can provide more efficient GPU acceleration support, which can greatly reduce coding time and bring significant efficiency improvement for content creators.

Through the test, we can see that the blue-based Ruixuan A770 has obvious occupation when carrying out AV1 coding. A 30-second 4K60 frame rate HD video is converted to AV1-encoded MP4 format in less than 20 seconds, and the file size is greatly reduced.

Artificial intelligence AI is another major feature of Intel's key layout productivity. Thanks to the XMX matrix engine, it has AI computing power beyond price and can cover the most common AI data types such as BF16 and INT8, which makes it possible for sharp graphics cards, especially the A770 with large graphics memory, to play a role in AI applications.

Here we use the software Topaz Video Enhance AI to test the AI magnification of the video. Then zoom in on the screencap material of a game. During the test, we tested the time-consuming of Ruixuan GPU acceleration and CPU-only status, respectively. The test results are as follows:

↑ dazzling A770 AI acceleration takes 2 minutes 33 seconds

↑ pure CPU computing takes 19 minutes and 52 seconds.

Through the test, we can see that the advantage of AI acceleration is very significant, even compared with the most flagship CPU, the performance gap of AI is nearly 9 times. So if you have AI-based picture, video application needs, you can try the blue halberd dazzling A770 graphics card + Topaz AI hardware and software combination.

Summary through the test results can be seen that the blue halberd A770 can be said to be a 2K game sweet-grade graphics card, the performance in XeSS is even more amazing, can achieve 2K light chase high frame rate play. In games that do not support XeSS and light chase, their raster performance is not bad, so they can be used as the main game graphics card.

In addition to the performance, the Blue halberd A770 also shows a serious attitude towards non-public graphics cards. It is not only good-looking and solid heat dissipation, but also can be seen from small designs such as packaging that Blue halberd attaches great importance to its own brand as an emerging graphics card manufacturer. If you can maintain this attitude, I believe Blue halberd can continue to hold the position of Intel's top non-public graphics card manufacturers.

For pure game players, the A750 can already meet the demand. For the productivity group, you may need to go to the blue halberd A770. At present, the blue halberd series graphics cards have been listed, although the blue halberd sharp series graphics cards are fully ahead of the public version, and the price is even cheaper.
