In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 465 are significantly better than the Nvidia GeForce GT 740 v2 Gainward 2GB Edition.

The GT 740 has a 386 MHz higher core clock speed but 12 fewer Texture Mapping Units than the GeForce GTX 465. The lower TMU count doesn't matter, though, as altogether the GT 740 manages to provide 5.1 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 GT 740 has a 386 MHz higher core clock speed than the GeForce GTX 465, but the GeForce GTX 465 has 16 more Render Output Units than the GT 740. As a result, the GeForce GTX 465 exhibits a 3.5 GPixel/s better Pixel Fill Rate than the GT 740. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GT 740 was released over three years more recently than the GeForce GTX 465, and so the GT 740 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 GT 740 has 1024 MB more video memory than the GeForce GTX 465, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The GeForce GTX 465 has 22.7 GB/sec greater memory bandwidth than the GT 740, which means that the memory performance of the GeForce GTX 465 is slightly better than the GT 740.

The GeForce GT 740 v2 Gainward 2GB Edition has 384 Shader Processing Units and the GeForce GTX 465 has 352. However, the actual shader performance of the GT 740 is 381 and the actual shader performance of the GeForce GTX 465 is 427. The GeForce GTX 465 having 46 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 GT 740.

The GT 740 transistor size technology is 12 nm (nanometers) smaller than the GeForce GTX 465. This means that the GT 740 is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GTX 465.

The GeForce GT 740 v2 Gainward 2GB Edition requires 64 Watts to run and the GeForce GTX 465 requires 200 Watts. We would recommend a PSU with at least 400 Watts for the GT 740 and a PSU with at least 550 Watts for the GeForce GTX 465. The GeForce GTX 465 requires 136 Watts more than the GT 740 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 GT 740.
