AMD Radeon GPUs: Everything you need to know Leave a comment


AMD continues to make headway in the laptop GPU scene, their latest offering is the Radeon RX 6000 series.  This is AMDs first foray into hardware-based ray tracing on laptops, an arena Nvidia has been in since its GeForce RTX 20 Mobile Series launched back in 2019. This is AMD’s first foray into hardware-based ray tracing, an arena Nvidia has been in since its GeForce RTX 20 Series launched back in 2019. AMD may be late to that particular party, but don’t count them out because of it. The RX 6000 series, based on AMD’s RDNA2 platform, perform competitively  with current-gen Nvidia RTX 30 Series cards.

These GPUS first came to market in June 2021 and consist of three SKUs. The Radeon RX 6600M, Radeon RX 6700M and Radeon 6800M, in order from lowest to highest performance. Let’s check some of the numbers.

GPU Model AMD Radeon RX 6800M AMD Radeon RX 6700M AMD Radeon RX 6600M
Compute Units 40 36 28
GDDR6 RAM 12GB 10GB 8GB
Infinity Cache 96MB 80MB 32MB
Game Clock 2300Mhz 2300Mhz 2177Mhz
Infinity Cache 96MB 80MB 32MB
GPU Power 145+W 135W 100W

The GPU’s Compute Units indicate the number of computational resources available to the GPU and includes the “Ray Accelerators,” which are specialized cores responsible for ray tracing effects. Due to fundamental architectural differences between AMD and Nvidia’s GPU designs, these numbers aren’t easily comparable to sNvidia’s CUDA cores. As we’ll show you, overall performance is best compared across brands by stacking up frame rates on similar workloads to see which cards can hit the highest numbers.

GDDR6 vRAM, the same sort found in Nvidia’s current 30 Series cards, is the amount of space the card has to store quickly-accessible graphical instructions needed for higher frame rate performance. AMD’s top-of-the-line RX 6800M GPU comes with 12GB of RAM compared to the Nvidia RTX 3080’s 8GB.
