In terms of overall gaming performance, the graphical capabilities of the HD Pentium G4400 and the Graphics 510 are equal.

The HD Pentium G4400 and the Graphics 510 have both the same core clock speed and the same Texture Fill Rate. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD Pentium G4400 and the Graphics 510 have both the same core clock speed and the same Pixel Fill Rate. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

Both the HD Pentium G4400 and the HD Graphics 510 Desktop were released at the same time, so are likely to be quite similar.

The HD Pentium G4400 and the HD Graphics 510 Desktop have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The memory bandwidth of the HD Pentium G4400 and the HD Graphics 510 Desktop are the same, which means the HD Pentium G4400 and the Graphics 510 have equal limitations when it comes to graphical data transfer.

Both the HD Pentium G4400 and the HD Graphics 510 Desktop have 12 Shader Processing Units. Having the same number of SPUs and using the same architecture means that the performance they offer can be compared by looking at the memory bandwidth, Texture and Pixel Rates. In this case, the two GPUs have extremely similar stats, so any gaming performance difference would most likely be negligible.

The HD Pentium G4400 requires 47 Watts to run and the HD Graphics 510 Desktop requires 47 Watts. We would recommend a PSU with at least 300 Watts for the HD Pentium G4400 and a PSU with at least 300 Watts for the Graphics 510. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.
