NVIDIA Quadro P400
The Quadro P400 is a GPU from NVIDIA released in 2017. This chip has a bad gaming score at 6% in our GPU benchmark.
The Quadro P400 has 2 GiB of GDDR5 memory, with a total memory bandwidth of 31 GB/s. The memory bus has a width of 64 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 P400 GPU core runs at a frequency of 1070 MHz and if power and temperature permits, it can boost up to 1252 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.
The performance specs of the Quadro P400 are this NVIDIA GPU has a pixel rate of 20 Gigapixels/s, the number of pixels the GPU is capable of outputting every second. Furthermore, it has a texture fill rate of 20 Gigatexels/s, the number of pixels the GPU can renderer per second.
As for rendering API support, the Quadro P400 supports up to DirectX 12.1. In addition, in cross-platform titles, OpenGL 4.5 features are supported. Newer APIs are usually more efficient, allowing for better performance in games and better graphical effects.
The raw technical specs of the Quadro P400 are: 256 total shading units (general purpose parallel cores capable of processing different aspects of the graphics pipeline), 16 texture mapping units (specialised processors for texture operations, this determines the texture rate) and 16 render output processors or units (the final step in the rendering pipeline, responsible for rasterising the image)
Power and thermals for the NVIDIA Quadro P400 are a TDP (Thermal Design Power) of 30 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.
