In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 5670 Gigabyte 1GB OC Edition are marginally better than the AMD Radeon R7 240 2GB.

The HD 5670 has a 220 MHz higher core clock speed and the same number of Texture Mapping Units as the R7 240. This results in the HD 5670 providing 4.4 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 HD 5670 has a 220 MHz higher core clock speed than the R7 240 and the same number of Render Output Units. This results in the HD 5670 providing 1.8 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 R7 240 was released over three years more recently than the HD 5670, and so the R7 240 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 5670 when running the latest games.

The R7 240 has 1024 MB more video memory than the HD 5670, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the HD 5670 has superior memory performance.

The HD 5670 has 35.2 GB/sec greater memory bandwidth than the R7 240, which means that the memory performance of the HD 5670 is noticeably better than the R7 240.

The Radeon R7 240 2GB has 320 Shader Processing Units and the Radeon HD 5670 Gigabyte 1GB OC Edition has 400. However, the actual shader performance of the R7 240 is 212 and the actual shader performance of the HD 5670 is 190. The R7 240 having 22 better shader performance is not particularly notable, as altogether the HD 5670 performs better when taking into account other relevant data.

The R7 240 transistor size technology is 12 nm (nanometers) smaller than the HD 5670. This means that the R7 240 is expected to run slightly cooler and achieve higher clock frequencies than the HD 5670. While they exhibit similar graphical performance, the R7 240 should consume less power than the HD 5670.

The Radeon R7 240 2GB requires 30 Watts to run but there is no entry for the Radeon HD 5670 Gigabyte 1GB OC Edition. We would recommend a PSU with at least 400 Watts for the R7 240.
