The Radeon HD 7870 is an AMD GPU.
This GPU is average at gaming with a score of 13% in our PC benchmark.
The Radeon HD 7870 has 2 GiB of memory. 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 HD 7870 GPU core runs at a frequency of 1000 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 HD 7870 supports up to DirectX 11.2. 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.
The AMD Radeon HD 7870 has a TDP of 175W, this is the amount of heat energy produced by the chip as a byproduct. The higher the TDP, the more heat is produced.
