In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 465 are significantly better than the AMD Radeon R7 250E Sapphire Ultimate 1GB Edition.

The R7 250E has a 193 MHz higher core clock speed than the GeForce GTX 465, but the GeForce GTX 465 has 12 more Texture Mapping Units than the R7 250E. As a result, the GeForce GTX 465 exhibits a 1.1 GTexel/s better Texture Fill Rate than the R7 250E. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The R7 250E has a 193 MHz higher core clock speed than the GeForce GTX 465, but the GeForce GTX 465 has 16 more Render Output Units than the R7 250E. As a result, the GeForce GTX 465 exhibits a 6.6 GPixel/s better Pixel Fill Rate than the R7 250E. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The R7 250E was released over three years more recently than the GeForce GTX 465, and so the R7 250E is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce GTX 465 when running the latest games.

The Radeon R7 250E Sapphire Ultimate 1GB Edition and the GeForce GTX 465 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GeForce GTX 465 has 30.7 GB/sec greater memory bandwidth than the R7 250E, which means that the memory performance of the GeForce GTX 465 is noticeably better than the R7 250E.

The Radeon R7 250E Sapphire Ultimate 1GB Edition has 512 Shader Processing Units and the GeForce GTX 465 has 352. However, the actual shader performance of the R7 250E is 348 and the actual shader performance of the GeForce GTX 465 is 427. The GeForce GTX 465 having 79 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX 465 delivers a noticeably smoother and more efficient experience when processing graphical data than the R7 250E.

The R7 250E transistor size technology is 12 nm (nanometers) smaller than the GeForce GTX 465. This means that the R7 250E is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GTX 465.

The Radeon R7 250E Sapphire Ultimate 1GB Edition requires 75 Watts to run and the GeForce GTX 465 requires 200 Watts. We would recommend a PSU with at least 400 Watts for the R7 250E and a PSU with at least 550 Watts for the GeForce GTX 465. The GeForce GTX 465 requires 125 Watts more than the R7 250E to run. The difference is significant enough that the GeForce GTX 465 may have an adverse affect on your yearly electricity bills in comparison to the R7 250E.
