preface:
If we say that in the past ten years Graphics card If there is any choice in the market, I believe it is just red and green, just like civil CPU Only red and blue can be selected in the market. Although the number is small, it also makes the computer hardware market enter benign competition. Compared with the CPU market, the video card market is more competitive, so the performance of video card games has improved rapidly, and its profits are also higher. Seeing this, Intel, which has been deeply rooted in the CPU market for many years, decided to return to the unique market again.
Little partners may have questions. Does Blue Factory return to the unique market? You know, Intel has made a unique statement! The one above is called The Real3D i740 Starfighter is the first unique model in Intel's history, which was born in 1998. It can be seen that the use of Intel as a graphics card is not new.
About the Xe HPG graphics card architecture update roadmap, ARC represents the name of this generation of graphics card architecture Alchemist, Next generation Battlemage. Well, this may be the romance of engineering men.
So what's Intel doing back in the exclusive market? It will be launched in Q1 2022 with Xe HPG architecture, Xe core. Each Xe core consists of 16 256 bit wide XVE vector engines and 16 1024 bit wide XMX matrix eXtensions, and several Xe cores together form a GPU of Xe HPG architecture.
Those who are familiar with the Intel CPU product line know that the product grade is Core i3~5~7~9, as well as the graphics card. At present, we still haven't seen the 9 series, but we believe that in the future, Intel 9 series graphics cards will definitely appear in the flagship graphics card market.
This time, Aru got Intel ARC A770 16GB graphics card, which is a full cup product in the A7 series high-performance camp in terms of its positioning and performance. use ACM-G10 core, based on Intel Xe HPG architecture, manufactured by TSMC N6 process, supports DirectX 12 Ultimate、 OpenGL 4.6. OpenCL 3.0 and Vulkan 1.3 have multiple APIs and PCIe 4.0 interfaces. The number of Render Slices is 8. Each Render Slice contains 4 Xe cores and 4 sets of ray tracing units.
Xe display engine provides a total of four display channels, supports HDMI 2.0b, DisplayPort 1.4a, and is also compatible with DisplayPort 2.0 10G. It can output up to two 8K resolution 60Hz HDR signals or four 4K resolution 120Hz HDR signals. Under 2K and 1080P resolutions, it can achieve 360Hz high brushing.
From the above table, we can see that the ARC A770 has two versions, namely 16G and 8GB GDDR6 video memory specifications. In addition to the different size of video memory capacity, the other aspects such as video memory bit width, grating unit, XMX engine, core frequency, etc. are completely the same, which is much higher than the precision knife method of friends.
Product unpacking:
First, let's take a look at the outer package of the product. I believe everyone here is very excited to see this familiar touch of Intel blue.
At first glance, I was attracted by the low-key and restrained appearance of the product. Although it is high-end, the shell does not have fancy RGB. Return to nature!
The unique shape of the fan blade can bring stronger wind pressure and airflow to the graphics card, and improve the heat dissipation effect.
The side of the graphics card is equipped with Intel ARC belief light, and the bottom is the light band.
8+6Pin power supply interface, the nearby 3pin interface is equipped with USB communication cable, which can be accessed through Software Control the video card light.
Ah Lu personally believes that the back of the graphics card is the beauty of this product. The bamboo ground between the high gloss texture and the matte processor and the back plate of the graphics card are white ARC A770 Limited Edition reveals that it is a limited edition!
In terms of I/O interface of graphics card, HDMI 2.1+3 * DP 2.0 interface can output up to two 8K resolution 60Hz HDR signals or four 4K resolution 120Hz HDR signals. Under 2K and 1080P resolutions, 360Hz high brush can be achieved. I have to mention that I really love the thickness of the ARC A770 double groove. Its thickness is thinner than the entry-level GTX1650 produced by friends. You should know that medium and high-end graphics cards, especially those without three slots, are too thick to sell. As far as players are concerned, the thicker the graphics card, the better Chassis Lower compatibility.
The PCB is marked with Intel logo, which proves that it is of Intel public design.
Don't ask me why I know. The question is that there is no Intel on the PCB of the two non-public Intel graphics cards I have.
Practical measurement:
When the light is good, the appearance of the ARC A770 is not cool enough. Try turning off the light?
I have to say that the blue aperture and light band really give people a full sense of technology.
But from another angle, it seems that something is wrong. What is it like? gas cooker?
Ah Lu, something's wrong with you
Cough, it's far away. Test platform:

In order to increase the readability of the article, Aru specially added the Lanji Intel ARC A750 Photon 8G OC graphics card for performance comparison.
GPU-Z Overview of graphics card hardware information
Performance test:
This game uses 2K resolution in software testing, so the partners who use price segment video cards must use 2K monitors, right?
List of 3DMARK achievements
Compared with the second brother ARC A750, the A770's DX12 runs a lot ahead, but the difference between the two is not big, about 5%.
Looking at the game test, I have to say that the performance of the ARC A770 in the traditional raster games is very impressive, and the frame rate is 60 or above, so it is no problem to play smoothly. Among them, two light pursuit games (Cyberpunk 2077, Watchdog: Legion) have not yet joined XeSS support, so the frame rate of ARC A770 is only about 35. However, the light chase game performance of Killer 3 and Tomb Raider Shadow added to XeSS is quite smooth.
Game comparison between ACR A770 and A750.
XeSS, the performance magic weapon of light pursuit game
For the difficult performance of ray tracing Hard bone Head, NVIDIA used DLSS, while AMD used FSR. Intel's magic weapon is XeSS, which is also based on the deep learning technology. By reducing the actual rendering resolution of the graphics card and amplifying it, Intel can significantly improve the game frame rate while keeping the image quality loss as low as possible. But unlike Red and Green Factory, Intel's XeSS adopts open source standards. If your graphics card supports DP4a instructions, you can implement XeSS.
and Xe HPG architecture graphics card native hardware level supports XeSS, so the game performance is better. At present, there are many games supporting XeSS. After all, Intel's influence in the PC industry cannot be underestimated.
The test of the four gears (balance, performance, quality and super quality) of the Intel XeSS function test of the 3DM shows that the frame rate of the image has been greatly improved after starting XeSS. No XeSS card has become a slide show and has transformed into a smooth silk screen of 44~68.
Game XeSS experience:
At present, both Killer 3 and Tomb Raider Shadow support XeSS.
According to the above data graph, games that support XeSS can have multiple gears that can be preset according to players' preferences. You can choose from quality, performance, balance and super quality. Even when XeSS is turned on to super quality, its game frame rate is still better than when XeSS is turned off.
Productivity testing:
Nowadays, video is the mainstream way of entertainment, and video bit rate is related to network bandwidth, which is also an important reason for the 4K and 8K online video jam of small pipe bandwidth. High video bit rate means high image quality.
Is the small water pipe doomed to have nothing to do with 4K and 8K picture quality? The appearance of AV1 code says it can! Compared with the common H.264 coding, AV1 coding can save up to 30% of the code rate on the premise that the image quality is basically the same as the former. It has a huge bandwidth advantage and is free to use.
Did you know that Intel ARC series graphics cards can provide native support for AV1 coding with the built-in Xe media engine? intel Ruixuan yes The world's first video card supporting AV1 codec.
At present, the latest version of Clipping Professional Edition has supported AV1 encoding. The AV1 transcoding rate of the ARC A770 is no less than that of my brother ARC A750. If you use it as a productivity, I believe the A770 is worth buying.
The AV1 transcoding rate of the ARC A770 is better than my brother's ARC A750. If you choose productivity, I believe the A770 is more worthy of purchase.
Overfrequency and power consumption:
The Intel Arc control center can improve the performance of the graphics card. To be conservative, Aru did not overclock the GPU, but chose to unlock the power consumption of the more secure GPU, from the default 190W to 228W. What about the game performance of the unlocked ARC A770?
After the graphics card was unlocked to 225W power consumption, the average game frame rate of Horizon 5 increased from 66 to 70.
The average frame rate of Tomb Raider Shadow game has been increased from 61 to 65.
The performance improvement is due to the higher acceleration frequency of the GPU. Of course, the power consumption is also rising. The power consumption of the ARC A770 toaster is 190W before unlocking the power consumption, 228W after unlocking the power consumption, and the GPU core temperature is only 1 ℃ different.
The bare metal fan noise of Intel ARC A770 is only 48dbA when it is fully loaded. Compared with the non-public ARC A750 with three fans, it is much quieter.
Summary:
In general, Intel ARC A770 is a graphics card worth buying with a high index. In addition to the recent news that A770 will reduce its price, some domestic merchants have followed, and the cost performance ratio has further improved. It is believed that with more and more games supporting XeSS in the future, AV1 codec is gradually applied, and Intel's optimization of graphics card drivers is becoming more and more perfect, ARC A series graphics cards, by virtue of their performance in light tracking games, are believed to be an important reason for its popularity in the video card market. Just the so-called The competition between the snipe and the clam is beneficial. What consumers like most is the benign market competition, so that they can buy high-quality and inexpensive products.
