AMD Radeon RX 6600M vs NVIDIA GeForce RTX 3070 Max-Q vs NVIDIA GeForce RTX 3080

AMD Radeon RX 6600M

The AMD Radeon RX 6600M is a mobile mid-range graphics card based on the Navi 23 chip (RDNA 2  architecture) manufactured in the modern 7nm process. It features 1,792 cores (28 CUs - compute units) and 8 GB of fast GDDR6 graphics memory connected with a 128 Bit memory bus. The chip also includes 32 MB Infinity Cache. The clock speed of the cores will depend on the laptop according to AMD. The power consumption (TDP settings) ranges from 50 - 100 Watt with different clock speeds (similar to Nvidia).

At 100 Watt the game clock reaches 2177 MHz (max boost 2416 MHz) and the performance should be similar to a RTX 3060 for laptops. When Raytracing effects are activated, it falls behind the GeForce GPUs.

The Navi 21 chip is manufactured at TSMC in the modern 7nm process.

NVIDIA GeForce RTX 3070 Max-Q

NVIDIA GeForce RTX 3080

The Nvidia GeForce RTX 3080 is high-end desktop graphics card based on the Ampere generation. It uses the big GA102 chip and offers 8,704 shaders and 10 GB GDDR6X graphics memory.

The gaming performance in 4k is clearly better than the old GeForce RTX 2080 Ti (approximately 15% faster). Therefore, even demanding games should run with maximum detail settings in 4k. Enabling raytracing will however reduce the framerate and therefore maximum details won't be playable. 

The RTX3080 is produced in 8nm at Samsung and rated at 320 Watt but the power efficiency is still quite good.
