In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 9800 GT are noticeably better than the AMD Radeon R7 240 2GB.

The R7 240 has a 130 MHz higher core clock speed than the GeForce 9800 GT, but the GeForce 9800 GT has 36 more Texture Mapping Units than the R7 240. As a result, the GeForce 9800 GT exhibits a 19 GTexel/s better Texture Fill Rate than the R7 240. 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 130 MHz higher core clock speed than the GeForce 9800 GT, but the GeForce 9800 GT has 8 more Render Output Units than the R7 240. As a result, the GeForce 9800 GT exhibits a 3.8 GPixel/s better Pixel Fill Rate than the R7 240. 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 GeForce 9800 GT, 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 GeForce 9800 GT when running the latest games.

The R7 240 has 1536 MB more video memory than the GeForce 9800 GT, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GeForce 9800 GT has superior memory performance.

The GeForce 9800 GT has 28.8 GB/sec greater memory bandwidth than the R7 240, which means that the memory performance of the GeForce 9800 GT is slightly better than the R7 240.

The Radeon R7 240 2GB has 320 Shader Processing Units and the GeForce 9800 GT has 112. However, the actual shader performance of the R7 240 is 212 and the actual shader performance of the GeForce 9800 GT is 168. The R7 240 having 44 better shader performance is not particularly notable, as altogether the GeForce 9800 GT performs better when taking into account other relevant data.

The R7 240 transistor size technology is 37 nm (nanometers) smaller than the GeForce 9800 GT. This means that the R7 240 is expected to run much cooler and achieve higher clock frequencies than the GeForce 9800 GT.

The Radeon R7 240 2GB requires 30 Watts to run and the GeForce 9800 GT requires 105 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 GeForce 9800 GT. The GeForce 9800 GT requires 75 Watts more than the R7 240 to run. The difference is significant enough that the GeForce 9800 GT may have an adverse affect on your yearly electricity bills in comparison to the R7 240.
