In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 650 Gigabyte OC 1GB Edition are massively better than the AMD Radeon X1800 XT.

The GTX 650 was released over three years more recently than the Radeon X1800 XT, and so the GTX 650 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Radeon X1800 XT when running the latest games.

The GTX 650 has 512 MB more video memory than the Radeon X1800 XT, 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 35.2 GB/sec greater memory bandwidth than the Radeon X1800 XT, which means that the memory performance of the GTX 650 is noticeably better than the Radeon X1800 XT.

The Radeon X1800 XT has 16 Shader Processing Units and the GeForce GTX 650 Gigabyte OC 1GB Edition has 384. However, the actual shader performance of the Radeon X1800 XT is 6 and the actual shader performance of the GTX 650 is 426. The GTX 650 having 420 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 Radeon X1800 XT.

The Radeon X1800 XT requires 113 Watts to run but there is no entry for the GeForce GTX 650 Gigabyte OC 1GB Edition. We would recommend a PSU with at least 400 Watts for the GTX 650, but we do not have a recommended PSU wattage for the Radeon X1800 XT.

GPU Mini Review

Mini ReviewRadeon X1800 XT is a performance GPU based on the 90nm variant of the R500 architecture.
It's based on the R520 Core and offers 16 Pixel Shaders, 16 TMUs and 16 ROPs, on a 256-bit of standard GDDR3. The central unit runs at 600MHz and the memory clock operates at up to 700MHz.
Its performance is considerably better than Radeon X1800 XL due to being higher clocked, as is the power consumption.
Most of today's games might be playable at medium settings although the low preset will have to suffice on some. As it's not based on a Shader-Unified architecture, both DirectX 10 & 11 games aren't supported.
GeForce 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.
