NVIDIA Quadro K620
Released in 2014, the Quadro K620 is a GPU from NVIDIA. According to our GPU Benchmark, this GPU is a bad card for gaming with a score of 6%.
The Quadro K620 has 2 GiB of DDR3 memory, with a total memory bandwidth of 28 GB/s. The memory bus has a width of 128 bits. When choosing a GPU, plan ahead and select a model with enough memory for your needs. High resolutions such as 4K require significantly more memory than 1080p as there is more data to display on the screen.
In terms of clock speed, the Quadro K620 GPU core runs at a frequency of 1000 MHz and if power and temperature permits, it can boost up to 1124 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 Quadro K620 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.
This chip has a Thermal Design Power of 45W: the total amount of waste heat generated. A card that runs hotter will need better cooling and will draw more power from the wall.
