Intel Arc A370M vs AMD Radeon 780M

Intel Arc A370M

The Intel Arc A370M is a dedicated mobile entry level graphics card for laptops based on Xe HPG microarchitecture. It uses the ACM-G11 chip and offers all 8 Xe-cores (128 ALUs), 8 ray tracing units and a 64-bit memory bus for 4 GB GDDR6 graphics memory. The chip integrates 7.2 billion transistors and the die measures 157 mm2.

The performance is in the entry level of dedicated graphics cards for laptops in 2022. AMD did publish some gaming benchmarks with medium settings in 5 games that showed that the Radeon RX 6500M is clearly faster. Intel only compared the A370M (with a faster CPU) to the slower Iris iGPU in the i7-1280P (see below). Thanks to the additional 2 cores and higher clock speeds, the entry level Arc A350M should be clearly left behind.

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 A370M is produced in 6nm at TSMC (N6 process) and supports dynamic power share (using Deep Link) with 12th gen Intel CPUs (Alder Lake).

AMD Radeon 780M

The AMD Radeon 780M is an integrated GPU in the Ryzen 7040 series for laptops (Phoenix, e.g. Ryzen 9 7940HS). The iGPU is based on the new RDNA3 architecture and has 12 CUs (= 768 shaders) clocked at up to 3 GHz (depending on the CPU model). As the predecessor Radeon 680M, the 780M supports hardware raytracing, although the performance is too slow to use it in current games.

Thanks to the new architecture and higher clock speeds, the Radeon 780M should be clearly faster then the old Radeon 680M. This means most demanding games should be playable in minimum graphics settings (like Cyberpunk 2077) and less demanding games like Fifa 23 can be played in higher settings and resolutions (1080p). In early 2023, the Radeon 780M is the fastest iGPU on the market.

Thanks to the modern 4nm process and clever power-saving features, the power consumption is comparatively low (according to AMD). The whole chip of the first two models can be configured between 15 - 54 Watt TDP.
