In terms of overall gaming performance, the graphical capabilities of the HD 8570 and the R7 240 are equal.

The HD 8570 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 HD 8570 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.

The R7 240 was released less than a year after the HD 8570, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The Radeon HD 8570 (OEM) and the Radeon R7 240 2GB 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 Radeon HD 8570 (OEM) and the Radeon R7 240 2GB are the same, which means the HD 8570 and the R7 240 have equal limitations when it comes to graphical data transfer.

Both the Radeon HD 8570 (OEM) 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 HD 8570 (OEM) requires 30 Watts to run and the Radeon R7 240 2GB requires 30 Watts. We would recommend a PSU with at least 400 Watts for the HD 8570 and a PSU with at least 400 Watts for the R7 240. 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.
