AMD Radeon R9 270X
The Radeon R9 270X is a GPU from AMD. This chip has an average gaming score at 15% in our GPU benchmark.
The Radeon R9 270X has 4 GiB of GDDR5 memory, with a total memory bandwidth of 1 GB/s. The memory bus has a width of 256 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 R9 270X GPU core runs at a frequency of 1000 MHz and if power and temperature permits, it can boost up to 1050 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 R9 270X supports up to DirectX 12. In addition, in cross-platform titles, OpenGL 4.4 features are supported. If your GPU is too old and doesn't support a newer API certain titles may not be playable.
Power and thermals for the AMD Radeon R9 270X are a TDP (Thermal Design Power) of 180 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.
