Intel Arc A370M vs AMD Radeon 660M

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 660M

The AMD Radeon 660M is an integrated GPU in the entry level Ryzen 6000 series for laptops (Rembrandt, e.g. Ryzen 5 6600U). The GPU is based on the RDNA2 architecture and has 6 of the 12 CUs (= 384 shaders) clocked at up to 1,900 MHz (depending on the CPU model). The 680M and 660M iGPUs are the first integrated graphics card with hardware raytracing support, although the performance is too slow to use it in current games.

Due to the halved CU count and lower core clock, the Radeon 660M is clearly slower than the Radeon 680M and most likely only on par with the old Radeon Vega 8 iGPUs. 

Thanks to the modern 6nm process and clever power-saving features, the power consumption is comparatively low (according to AMD), so the graphics card can also be used for slim and light notebooks (depending on the CPU model).
