In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 670 PNY 2GB Edition are massively better than the Nvidia GeForce GTX 650 Zotac AMP! Edition.

The GTX 650 has a 274 MHz higher core clock speed than the GTX 670, but the GTX 670 has 80 more Texture Mapping Units than the GTX 650. As a result, the GTX 670 exhibits a 64.5 GTexel/s better Texture Fill Rate than the GTX 650. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 650 has a 274 MHz higher core clock speed than the GTX 670, but the GTX 670 has 16 more Render Output Units than the GTX 650. As a result, the GTX 670 exhibits a 10.3 GPixel/s better Pixel Fill Rate than the GTX 650. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 650 was released less than a year after the GTX 670, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GeForce GTX 670 PNY 2GB Edition and the GeForce GTX 650 Zotac AMP! Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GTX 670 has 102.7 GB/sec greater memory bandwidth than the GTX 650, which means that the memory performance of the GTX 670 is massively better than the GTX 650.

The GeForce GTX 670 PNY 2GB Edition has 1344 Shader Processing Units and the GeForce GTX 650 Zotac AMP! Edition has 384. However, the actual shader performance of the GTX 670 is 1317 and the actual shader performance of the GTX 650 is 457. The GTX 670 having 860 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 670 delivers a massively smoother and more efficient experience when processing graphical data than the GTX 650.

The GeForce GTX 670 PNY 2GB Edition requires 170 Watts to run but there is no entry for the GeForce GTX 650 Zotac AMP! Edition. We would recommend a PSU with at least 500 Watts for the GTX 670.

GPU Mini Review

Mini ReviewGeForce GTX 670 PNY 2GB Edition is a renamed GeForce GTX 670 with no new features - not even a new cooling system. Its performance is exactly like the reference card.GeForce GTX 650 Zotac AMP! Edition is a special edition of the fast-middle-class GeForce GTX 650 2GB.
This special edition comes with a custom cooling solution and overclocked out of the box to 1089MHz (core-clock) and to 1400MHz (memory clock).
The overclocking is extreme but until benchmarks become available, this GPU's rank is subject to change.
