AMD Radeon HD 7990 Benchmark and Specs

AMD Radeon HD 7990

Thanks to our GPU Benchmark, we have measured the AMD Radeon HD 7990 as an average gaming performer a score of 1743 points.

The Radeon HD 7990 has 3 GiB of GDDR5 memory, with a total memory bandwidth of 281 GB/s. The memory bus has a width of 384 bits. If you plan on gaming at higher resolutions with higher quality textures, more memory is important. Without enough memory, performance will be degraded.

In terms of clock speed, the Radeon HD 7990 GPU core runs at a frequency of 950 MHz and if power and temperature permits, it can boost up to 1000 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.

As for rendering API support, the Radeon HD 7990 supports up to DirectX 11.20. In addition, in cross-platform titles, OpenGL 4.40 features are supported. Newer APIs are usually more efficient, allowing for better performance in games and better graphical effects.

This chip has a Thermal Design Power of 375W: the total amount of waste heat generated. A card that runs hotter will need better cooling and will draw more power from the wall.
