Apple M3 8-Core GPU vs AMD Radeon RX 6450M

Apple M3 8-Core GPU

► remove from comparison Apple M3 8-Core GPU

The Apple M3 GPU is an integrated graphics card offering 10 cores designed by Apple and integrated in the Apple M3 SoC. It uses the unified memory architecture of the M3 SoC (up to 24 GB LPDDR5-6400 with 100 GB/s bandwidth). The GPU uses a new architecture with support for mesh shading and ray tracing. Dynamic caching is also a new feature that should only us as much shared memory as needed.

The old M2 SoC showed a difference of around 15% between the 8-core and 10-core variant. Therefore, we expect a similar difference for the M3 models. This means, the M3 8-core version should be slightly faster than the 10-core GPU in the Apple M2.

The M3 chip is manufactured in the new 3nm process at TSMC (most likely N3B). The power limit should be around the same 15 Watt as the 10-core variant.

AMD Radeon RX 6450M

► remove from comparison AMD Radeon RX 6450M

The AMD Radeon RX 6450M is a mobile entry-level graphics card based on the Navi 24 chip (RDNA 2  architecture) manufactured in the modern 6nm process. It features 768 cores (12 CUs - compute units) and 4 GB of fast GDDR6 graphics memory connected with a small 64 Bit memory bus. The chip also includes 16 MB Infinity Cache. The game clock speed is specified at 2220 MHz. 

The performance should be slightly better than the old RX 6300M (slower clocked, but higher memory bandwidth) and therefore positioned in the entry level. This means, the GPU is best suited for 1080p gaming in medium to high detail settings.

The Navi 24 chip is manufactured at TSMC in the modern 6nm process and the 6450M can be configured from 25 - 50 Watt TGP.
