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 93% 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. 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 6600 XT GPU core runs at a frequency of 1968 MHz and if power and temperature permits, it can boost up to 2589 MHz. The core clock is directly related to the performance of a GPU, the higher the clock, the more processing can be done per second. A higher clock does not guarantee better performance by itself, this also depends on the number of shading units and other elements of the pipeline.

The performance specs of the Radeon RX 6600 XT are a raw floating-point performance of 10.6 TFLOPS : this represents the number of floating point (decimal) operations completed per second. In addition, this AMD GPU has a pixel rate of 166 Gigapixels/s, the number of pixels the GPU is capable of outputting every second. Furthermore, it has a texture fill rate of 331 Gigatexels/s, the number of pixels the GPU can renderer per second.

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. Newer APIs are usually more efficient, allowing for better performance in games and better graphical effects.

The raw technical specs of the Radeon RX 6600 XT are: 2048 total shading units (general purpose parallel cores capable of processing different aspects of the graphics pipeline), 128 texture mapping units (specialised processors for texture operations, this determines the texture rate) and 64 render output processors or units (the final step in the rendering pipeline, responsible for rasterising the image)

Power and thermals for the AMD Radeon RX 6600 XT are a TDP (Thermal Design Power) of 160 watts. This measures the amount of heat the GPU produces when running at 100%. This isn't a measure of power consumption, but it's a good estimate.
