In terms of overall gaming performance, the graphical capabilities of the Intel HD Pentium G4520 are marginally better than the AMD Radeon R7 240 2GB.

The R7 240 has a 380 MHz higher core clock speed and 4 more Texture Mapping Units than the HD Pentium G4520. This results in the R7 240 providing 9 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The R7 240 has a 380 MHz higher core clock speed than the HD Pentium G4520 and the same number of Render Output Units. This results in the R7 240 providing 3 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD Pentium G4520 was released over a year more recently than the R7 240, and so the HD Pentium G4520 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the R7 240.

The R7 240 has 2048 MB video memory, but the HD Pentium G4520 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The HD Pentium G4520 has 24 Shader Processing Units and the Radeon R7 240 2GB has 320. However, the actual shader performance of the HD Pentium G4520 is 202 and the actual shader performance of the R7 240 is 212. The R7 240 having 10 better shader performance and an altogether better performance when taking into account other relevant data means that the R7 240 delivers a marginally smoother and more efficient experience when processing graphical data than the HD Pentium G4520.

The HD Pentium G4520 transistor size technology is 14 nm (nanometers) smaller than the R7 240. This means that the HD Pentium G4520 is expected to run slightly cooler and achieve higher clock frequencies than the R7 240. While they exhibit similar graphical performance, the HD Pentium G4520 should consume less power than the R7 240.

The HD Pentium G4520 requires 47 Watts to run and the Radeon R7 240 2GB requires 30 Watts. We would recommend a PSU with at least 300 Watts for the HD Pentium G4520 and a PSU with at least 400 Watts for the R7 240. The HD Pentium G4520 requires 17 Watts more than the R7 240 to run. The difference is not significant enough for the HD Pentium G4520 to have a noticeably larger impact on your yearly electricity bills than the R7 240.
