Intel Arc A770M vs ARM Mali-G76 MP16

Intel Arc 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).

ARM Mali-G76 MP16

The ARM Mali-G76 MP16 is an integrated high-end graphics card for ARM based SoCs (mostly Android based). It was introduced early 2019 in the Kirin 990 5G and according to Huawei should be about 6% faster and 20% more efficient than a Adreno 640 in a Snapdragon 855. It integrates 16 of the 20 possible cores and is based on the second generation of the Bifrost architecture. According to ARM it offers improvements in the machine learning efficiency and a bigger tile buffer for 16x anti-aliasing. Compared to the old Mali-G72, the G76 should offer twice the performance per cluster.

The GPU supports all modern graphics APIs like OpenGL ES 3.2, Vulkan 1.0, OpenCL 2.0, DirectX 12 FL11_1 and Renderscript.
