AMD Radeon RX 6800M

The AMD Radeon RX 6800M 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 all 2,560 shaders (= 40 CUs), 160 TMUs, and 64 ROPs and therefore is similar to the desktop Radeon RX 6700 XT. The 192 Bit memory system connects 12 GB GDDR6 with 2 GHz memory clock. Furthermore, the RX6800M includes 96 MB Infinity Cache. AMD specified 2.3 GHz game clock for 11.8 TFLOPS theoretical performance at a TDP of 145 Watt. This means the GPU is in theory 11% faster than the RX 6700M.

The gaming performance of the RX 6800M (e.g. in the Asus ROG Strix G15) is positioned between a RTX 3070 and 3080. In some games the GPU can even surpass a fast RTX 3080. On the other side, when Raytracing effects are activated, it falls behind the GeForce GPUs.

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