In terms of overall gaming performance, the graphical capabilities of the R7 240 and the R7 240 are equal.

The R7 240 and the R7 240 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 R7 240 and the R7 240 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 Radeon R7 240 Sapphire 4GB Edition and the Radeon R7 240 2GB were released at the same time, so are likely to be quite similar.

The R7 240 has 1024 MB more video memory than the R7 240, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the R7 240 also has superior memory performance overall.

The memory bandwidth of the Radeon R7 240 Sapphire 4GB Edition and the Radeon R7 240 2GB are the same, which means the R7 240 and the R7 240 have equal limitations when it comes to graphical data transfer.

Both the Radeon R7 240 Sapphire 4GB Edition and the Radeon R7 240 2GB have 320 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 Radeon R7 240 Sapphire 4GB Edition requires 35 Watts to run and the Radeon R7 240 2GB requires 30 Watts. We would recommend a PSU with at least 400 Watts for the R7 240 and a PSU with at least 400 Watts for the R7 240. The R7 240 requires 5 Watts more than the R7 240 to run. The difference is not significant enough for the R7 240 to have a noticeably larger impact on your yearly electricity bills than the R7 240.
