Intel announced three new desktop independent graphics: full 256bit video memory, flagship model finally unveiled

Intel announced the ARC discrete graphics card very early, but the collection of the A380 was long after the second quarter, and it was still exclusive to the Chinese market. However, other ARC graphics cards have not been officially announced, which also makes everyone anxious. Now that the flagship graphics cards of AMD and NVIDIA have fallen to a low point, everyone's interest in Intel's unique graphics is getting smaller and smaller. However, today Intel officially announced several other products of Ruixuan desktop graphics card, which also means that Intel's products in the independent display market this year have settled. From the perspective of Intel's layout, in terms of graphics card models, Intel is far inferior to AMD and NVIDIA. Of course, considering that this is the first series of products that Intel has repeated in the independent graphics market for many years, it is normal not to design so many models. . The division of Intelde ARC desktop graphics cards is similar to that of processors. They are divided into ARC 3/5/7 series. Among them, there are two high-end 7 series, one performance-level 5 series, and only one mainstream 3 series. A380 has been released. Intel announced three products, A770, A750 and A580 this time. All three graphics cards use ACM-G10 chips. Of course, graphics cards with different positioning have different specifications to a certain extent. Obviously, the knife method is still rough. , but at least learned a lot from AMD and NVIDIA. All three graphics cards announced by Intel use 256bit video memory, which is stronger than AMD and NVIDIA. All graphics cards will be equipped with 8GB video memory, and the flagship A770 may also be equipped with 16GB video memory. The A770 and A750 have 32 and 28 Xe cores of the Xe-HPG architecture, respectively, with a core frequency of 2100MHz and 2050MHz, while the A580 has 24 Xe cores with a core frequency of 1700MHz. From this point of view, the performance difference between these three graphics cards will not be very large. After all, the difference in the number of Xe cores is not exaggerated. In addition, each graphics card supports HDR, Variable Refresh Rate (VRR), XeSS, ray tracing, customizable actions using ARC Control, AV1 codec, and other dedicated hardware video codecs, and more. In addition, in other functions, the Xe display engine of all graphics cards has 4 display channels, supports HDMI 2.0b, DisplaysPort 1.4a and 2.0, and supports output of up to 2 8K60 HDR, or 4 4K120 HDR, and both 2K and 1080p can be output. Up to 360Hz, and supports Adaptive Sync, Speed ​​Sync and Smooth Sync three display synchronization technologies. But unfortunately, these output functions can only be achieved by DP, because Intel's graphics card does not support HDMI 2.1 interface, so the bandwidth is not enough. In terms of performance, Intel has previously stated that the performance of the A770 is between the RTX 3060 and the RTX 3060 Ti, so the performance of the A750 is about the same as the RTX 3060, while the performance of the A580 is lower, but it should be stronger than the RTX 3050. In general, the performance of Intel's generation of ARC graphics cards is not expected to be too high, but whether it is worth buying depends on the specific price. If the A770 can be below 2500 yuan, then the price/performance ratio is still somewhat. Now it depends on how Intel sets the price. The A380 will sell for about 1,000 yuan. There are only four products in total, so the price difference will not be too big.
