AMD Radeon RX 6600M

The Radeon RX 6600M is an AMD GPU that was released in May 2021. This GPU is average at gaming with a score of 28% in our PC benchmark.

The Radeon RX 6600M has 8 GiB of GDDR6 memory, with a total memory bandwidth of 218 GB/s. The memory bus has a width of 128 bits. More memory is beneficial when gaming at high resolutions as the memory needs to store the frame buffer and all the game textures. If you run out of memory, you will experience poor performance as the GPU needs to swap data in and out of the memory as it is used.

In terms of clock speed, the Radeon RX 6600M GPU core runs at a frequency of 2068 MHz and if power and temperature permits, it can boost up to 2416 MHz. The clock runs at a speed called the clock speed. It dictates the number of updates per second that the GPU can process. Overclocking a chip, which means increasing the clock speed will improve the performance. However, thermals and power efficiency may be diminished.

As for rendering API support, the Radeon RX 6600M supports up to DirectX 12. In addition, in cross-platform titles, OpenGL 4.6 features are supported. Higher level APIs such as DirectX 12 give more control to the game developer and can allow them to improve the graphics and performance.

This chip has a Thermal Design Power of 100W: the total amount of waste heat generated. A card that runs hotter will need better cooling and will draw more power from the wall.
