In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 650 Gigabyte OC 1GB Edition are massively better than the Nvidia GeForce GT 330.

The GTX 650 has a 610 MHz higher core clock speed but 24 fewer Texture Mapping Units than the GeForce GT 330. The lower TMU count doesn't matter, though, as altogether the GTX 650 manages to provide 7.5 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 GTX 650 has a 610 MHz higher core clock speed than the GeForce GT 330 and the same number of Render Output Units. This results in the GTX 650 providing 9.8 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 650 was released over a year more recently than the GeForce GT 330, and so the GTX 650 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce GT 330.

The GTX 650 has 768 MB more video memory than the GeForce GT 330, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 650 also has superior memory performance overall.

The GTX 650 has 63.7 GB/sec greater memory bandwidth than the GeForce GT 330, which means that the memory performance of the GTX 650 is much better than the GeForce GT 330.

The GeForce GTX 650 Gigabyte OC 1GB Edition has 384 Shader Processing Units and the GeForce GT 330 has 112. However, the actual shader performance of the GTX 650 is 426 and the actual shader performance of the GeForce GT 330 is 140. The GTX 650 having 286 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 650 delivers a massively smoother and more efficient experience when processing graphical data than the GeForce GT 330.

The GTX 650 transistor size technology is 27 nm (nanometers) smaller than the GeForce GT 330. This means that the GTX 650 is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GT 330.

The GeForce GT 330 requires 75 Watts to run but there is no entry for the GTX 650. We would recommend a PSU with at least 400 Watts for the GTX 650 and a PSU with at least 300 Watts for the GeForce GT 330. The GTX 650 has been recommended a PSU with 100 Watts more than the GeForce GT 330. The difference is significant enough that the GTX 650 may have an adverse affect on your yearly electricity bills in comparison to the GeForce GT 330.

GPU Mini Review

Mini ReviewGeForce GTX 650 Gigabyte OC 1GB Edition is a special edition of the fast-middle-class GeForce GTX 650 1GB.
This special edition comes overclocked out of the box to 1110MHz and features a custom-designed 10 cm cooler.
Benchmarks indicate a 4% performance boost when compared to the reference card and so this GPU is suitable for medium to high settings on most demanding games but not with extreme resolutions.
GeForce GT 330 is a middle-class GFX based on the 2009, 65nm, first-generation unified architecture.
It's based on the G92b Core and offers 112 Shader Processing Units, 56 TMUs and 16 ROPs, on a 128-bit memory interface of standard DDR2. The central unit runs at 500MHz and the memory clock operates at up to 510MHz.
The number of Shaders cannot be compared to GeForce GT 340 due to being based on a different architecture. It's therefore an underclocked GeForce 8800/9800 GT, equipped with a 128-bit bus and that should perform like GeForce 9600 GSO.
Today's modern demanding games will have to be played at medium settings to achieve fluent frame rates. DirectX 11 games aren't supported.
