AMD Radeon RX 6600 XT

The Radeon RX 6600 XT is a GPU from AMD released in 2021. This chip has a very good gaming score at 54% in our GPU benchmark.

The Radeon RX 6600 XT has 8 GiB of GDDR6 memory, with a total memory bandwidth of 250 GB/s. The memory bus has a width of 128 bits. When choosing a GPU, plan ahead and select a model with enough memory for your needs. High resolutions such as 4K require significantly more memory than 1080p as there is more data to display on the screen.

In terms of clock speed, the Radeon RX 6600 XT GPU core runs at a frequency of 1968 MHz and if power and temperature permits, it can boost up to 2589 MHz. A clock speed is the frequency at which the GPU updates. A higher speed means more processing can happen per cycle. This is useful only when comparing cards of the same generation, as other architectures may process more or less per clock.

As for rendering API support, the Radeon RX 6600 XT supports up to DirectX 12. In addition, in cross-platform titles, OpenGL 4.6 features are supported. If your GPU is too old and doesn't support a newer API certain titles may not be playable.

This chip has a Thermal Design Power of 160W: the total amount of waste heat generated. A card that runs hotter will need better cooling and will draw more power from the wall.
