AMD Radeon RX 6700M vs Apple M3 Pro 14-Core GPU vs AMD Radeon RX 6450M

AMD Radeon RX 6700M

The AMD Radeon RX 6700M is a mobile high-end graphics card for gaming laptops. It uses the Navi 22 chip based on the new RDNA 2 architecture. It uses 2,304 of the 2,560 shaders (= 36 CUs), 144? TMUs, and 64 ROPs. The 160 Bit memory system connects 10 GB GDDR6 with 2 GHz memory clock. Furthermore, the RX6800M includes 80 MB Infinity Cache. AMD specified 2.3 GHz game clock for 10.6 TFLOPS theoretical FP32 performance at a TDP of 135 Watt. This means the GPU is in theory 11% slower than the RX 6800M.

The gaming performance of the RX 6700M is positioned slightly below a RTX 3070. When Raytracing effects are activated, it falls behind the GeForce GPUs.

The Navi 22 chip is manufactured at TSMC in the modern 7nm process.

Apple M3 Pro 14-Core GPU

► remove from comparison

The Apple M3 Pro 14-Core GPU is a self-designed graphics card in the Apple M3 Pro (with 11 CPU cores) and offers fourteen of the eighteen cores available on the chip. The graphics card uses a new architecture and now offers dynamic caching, mesh shading and ray tracing acceleration.

The GPU can access up to 24 GB LPDDR5-6400 unified memory via a 192-bit memory bus (max 150 GBit/s). Thanks to dynamic caching, the GPU only reserves as much memory as is required.

The entire chip is manufactured in the current 3nm process (probably N3B) at TSMC.

AMD Radeon RX 6450M

► remove from comparison

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.
