Intel Arc A770M

Intel A770M

The Intel Arc A770M is a dedicated mobile lower- mid-range graphics card for laptops based on Xe HPG microarchitecture. It uses the ACM-G10 chip and offers all of the 32 Xe-cores (512 ALUs), 32 ray tracing units and a 256-bit memory bus for 12 GB GDDR6 graphics memory. The chip can clock from 300 MHz (low frequency mode) to 1650 MHz (high frequency) or in short bursts 2050 MHz (Turbo). The chip integrates 21.7 billion transistors, uses a BGA2660 package (soldered), and the die measures 406 mm2.

The performance of the Arc A770M is not yet known. The power consumption is similar to a RTX 3070 and therefore we see the performance slightly below a RTX 3070 mobile.

The chip also integrates two media engines for VP9, AVC, HEVC, and AV1 8k en- and decoding. The 4 display pipes support up to 4x 4k120 HDR via DMI 2.0B or DisplayPort 2.0 10G. 

The A770M is produced in 6nm at TSMC (N6 process) and supports dynamic power share (using Deep Link) with 12th gen Intel CPUs (Alder Lake).
