Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 650 2GB are marginally better than the AMD Radeon HD 7750 1GB GDDR5.
The GTX 650 has a 258 MHz higher core clock speed and the same number of Texture Mapping Units as the HD 7750. This results in the GTX 650 providing 8.3 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 258 MHz higher core clock speed than the HD 7750 and the same number of Render Output Units. This results in the GTX 650 providing 4.1 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 less than a year after the HD 7750, and so they are likely to have similar driver support for optimizing performance when running the latest games.
The GTX 650 has 1024 MB more video memory than the HD 7750, 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 8 GB/sec greater memory bandwidth than the HD 7750, which means that the memory performance of the GTX 650 is marginally better than the HD 7750.
The GeForce GTX 650 2GB has 384 Shader Processing Units and the Radeon HD 7750 1GB GDDR5 has 512. However, the actual shader performance of the HD 7750 is 332.8. The GTX 650 having 51.2 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 650 delivers a marginally smoother and more efficient experience when processing graphical data than the HD 7750.
The GeForce GTX 650 2GB requires 64 Watts to run and the Radeon HD 7750 1GB GDDR5 requires 55 Watts. We would recommend a PSU with at least 400 Watts for the GTX 650 and a PSU with at least 400 Watts for the HD 7750. The GTX 650 requires 9 Watts more than the HD 7750 to run. The difference is not significant enough for the GTX 650 to have a noticeably larger impact on your yearly electricity bills than the HD 7750.

|Mini Review||GeForce GTX 650 2GB is a fast-middle-class GPU part of the 600 Series released by NVIDIA in 2012. |
This version features a frame buffer of 2GB. It's known that this GPU does not benefit in any way from a 2GB frame buffer and so this GPU's performance is on level with the 1GB variant. Check the page of the 1GB version for more information about but please note this GPU is just a fast GT 640, paired with GDDR5. Its performance is nothing like next in series - GeForce GTX 650 Ti and barely any fast than previous GTX 550 Ti.
|Radeon HD 7750 1GB GDDR5 is a fast-middle-class GPU based on the 28nm GCN (Graphics Core Next) architecture. |
It's based on Cape Verde Chip (Pro variant) and offers 512 Shader Processing Units, 32 TMUs and 16 ROPs on a 128-bit memory interface of fast GDDR5 (though some DDR3 variants were also released). The central unit is clocked at 800MHz while the memory clock operates at 1125MHz. Expect a power consumption of up to 55 Watt.
Benchmarks indicate today's modern games can be played at high settings using a 1080p resolution while most modern demanding games such as Metro 2033 will require reduced resolutions to be played optimally.
This GPU can be paired with an average Quad Core.
