NVIDIA GeForce RTX 4080 Benchmark

NVIDIA GeForce RTX 4080

Thanks to our GPU Benchmark, we have measured the NVIDIA GeForce RTX 4080 as an incredible gaming performer a score of 205%.

The GeForce RTX 4080 has 16 GiB of GDDR6X memory, with a total memory bandwidth of 662 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 GeForce RTX 4080 GPU core runs at a frequency of 2025 MHz and if power and temperature permits, it can boost up to 2375 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 GeForce RTX 4080 supports up to DirectX 12.00. In addition, in cross-platform titles, OpenGL 4.60 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 NVIDIA GeForce RTX 4080 are a TDP (Thermal Design Power) of 420 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.
