NVIDIA GeForce RTX 4090 Benchmark and Specs

NVIDIA GeForce RTX 4090

Released in 2022, the GeForce RTX 4090 is a GPU from NVIDIA. According to our GPU Benchmark, this GPU is an incredible card for gaming with a score of 211%.

The GeForce RTX 4090 has 24 GiB of GDDR6X memory. The memory bus has a width of 384 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 4090 GPU core runs at a frequency of 2235 MHz and if power and temperature permits, it can boost up to 2520 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 GeForce RTX 4090 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 4090 are a TDP (Thermal Design Power) of 450 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.
