The GPU main body of Arc A770, Arc A750, and Arc A580 is 'ACM-G10' equipped with up to 32 Xe HPG microarchitecture cores for gaming. As a feature of the Xe HPG microarchitecture, the 'Xe Media Engine' is built into the video processor. In addition, Intel's own XMX AI acceleration, graphics pipeline optimized for DirectX 12 Ultimate, Xe Media engine adjusted for creators, Xe Display engine compatible with DisplayPort 2.0 UHBR10, etc. are implemented.

Intel provides benchmark test results for the Arc A770, which is the flagship model of the Arc A series, compared to the NVIDIA GeForce RTX 3060. The bar graph below shows the maximum frame rate of the RTX 3060 (green) and Arc A770 (blue) with 1080p resolution and ray tracing enabled in various game titles.

Furthermore, the performance in each game when combining the high resolution technology 'Xe Super Sampling (XeSS)' installed in Arc with ray tracing is as follows. XeSS has a performance mode and a balanced mode, and Intel said it saw a performance improvement of up to 2.13x when combining performance modes and up to 1.76x when combining balanced modes.

As for the sales time, Arc A770 and Arc A750 will be 'soon' and Arc A580 will be 'later'. At the time of writing the article, Intel has not disclosed the recommended price of graphics boards, including those made by partner companies.

In addition, Intel also publishes a movie that answers users' questions about the Arc A series below.
