In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTS 250 v2 Gainward Deep Green 512MB Edition are marginally better than the Nvidia GeForce GT 640 v3 Zotac 2GB Edition.

The GT 640 has a 371 MHz higher core clock speed than the GTS 250, but the GTS 250 has 48 more Texture Mapping Units than the GT 640. As a result, the GTS 250 exhibits a 26.5 GTexel/s better Texture Fill Rate than the GT 640. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GT 640 has a 371 MHz higher core clock speed than the GTS 250, but the GTS 250 has 8 more Render Output Units than the GT 640. As a result, the GTS 250 exhibits a 2.4 GPixel/s better Pixel Fill Rate than the GT 640. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GT 640 was released over three years more recently than the GTS 250, and so the GT 640 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GTS 250 when running the latest games.

The GT 640 has 1536 MB more video memory than the GTS 250, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GT 640 also has superior memory performance overall.

The GTS 250 has 17.5 GB/sec greater memory bandwidth than the GT 640, which means that the memory performance of the GTS 250 is slightly better than the GT 640.

The GeForce GTS 250 v2 Gainward Deep Green 512MB Edition has 128 Shader Processing Units and the GeForce GT 640 v3 Zotac 2GB Edition has 384. However, the actual shader performance of the GTS 250 is 216 and the actual shader performance of the GT 640 is 402. The GT 640 having 186 better shader performance is not particularly notable, as altogether the GTS 250 performs better when taking into account other relevant data.

The GT 640 transistor size technology is 37 nm (nanometers) smaller than the GTS 250. This means that the GT 640 is expected to run much cooler and achieve higher clock frequencies than the GTS 250. While they exhibit similar graphical performance, the GT 640 should consume less power than the GTS 250.

The GeForce GTS 250 v2 Gainward Deep Green 512MB Edition requires 110 Watts to run and the GeForce GT 640 v3 Zotac 2GB Edition requires 49 Watts. We would recommend a PSU with at least 500 Watts for the GTS 250 and a PSU with at least 350 Watts for the GT 640. The GTS 250 requires 61 Watts more than the GT 640 to run. The difference is significant enough that the GTS 250 may have an adverse affect on your yearly electricity bills in comparison to the GT 640.
