NVIDIA Quadro K420 Benchmark and Specs

NVIDIA Quadro K420

The Quadro K420 is a GPU from NVIDIA released in 2014. This chip has a bad gaming score with 93 points in our GPU benchmark.

The Quadro K420 has 1 GiB of DDR3 memory, with a total memory bandwidth of 27 GB/s. The memory bus has a width of 128 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 Quadro K420 GPU core runs at a frequency of 780 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 Quadro K420 supports up to DirectX 11. In addition, in cross-platform titles, OpenGL 4.5 features are supported. If your GPU is too old and doesn't support a newer API certain titles may not be playable.

The NVIDIA Quadro K420 has a TDP of 41W, this is the amount of heat energy produced by the chip as a byproduct. The higher the TDP, the more heat is produced.
