The AMD Radeon RX 7900M is a mobile upper high-end graphics card based on the Navi 31 chip (RDNA 3 architecture) manufactured in 5nm. It features 4,608 cores (72 CUs - compute units) and 16 GB of fast GDDR6 graphics memory connected with a 256 Bit memory bus. The chip also includes 64 MB Infinity Cache. The clock speed of the cores will depend on the laptop according to AMD. The specified game clock speed is 1825 MHz (most likely at 180 W TGP).
AMD compares the performance to the mobile RTX 4080 and shows a number of games where the 7900M is on average 7% faster. Raytracing is supported in hardware, but usually slower than the Nvidia counterpart. Nvidia also has the advantage of DLSS support in selected games.
The Navi 31 chip is manufactured at TSMC in the current 5nm process. The power consumption (TGP) is specified at 160 to 180 Watt (200 Watt including SmartShift from the CPU).
The Apple M2 8-core GPU is an integrated graphics card offering 8 of the 10 cores designed by Apple and integrated in the Apple M2 SoC. It uses the unified memory architecture of the M2 SoC (up to 24 GB LPDDR5-6400 with 100 GB/s bandwidth) and should offer 128 execution units.
The performance is positioned right between the old 8-core model in the M1 GPU and the higher end 10-core model in the M2. The theoretical performance should be around 2.9 Teraflops, as the 8-core version offers the same 1,398 MHz maximum clock rate as the 10-core version. Compared to other iGPUs from AMD and Intel, the M2 benefits greatly from the unified memory architecture and the high bandwidth.
The M2 chip is manufactured in the second generation 5nm process at TSMC (most likely N5P). The power consumption is around 10 Watt (in our tests under load of the MBP13) compared to the 13.5W of the 10-core version.
