In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 6800 XT are noticeably better than the AMD Radeon X1550.

The Radeon X1550 was released over a year more recently than the GeForce 6800 XT, and so the Radeon X1550 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce 6800 XT.

Both GPUs exhibit very poor performance, so rather than upgrading from one to the other you should consider looking at more powerful GPUs. Neither of these will be able to run the latest games in any playable way.

The Radeon X1550 and the GeForce 6800 XT have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The Radeon X1550 has 1.6 GB/sec greater memory bandwidth than the GeForce 6800 XT, which means that the memory performance of the Radeon X1550 is marginally better than the GeForce 6800 XT.

The Radeon X1550 has 4 Shader Processing Units and the GeForce 6800 XT has 12. However, the actual shader performance of the Radeon X1550 is 1 and the actual shader performance of the GeForce 6800 XT is 4. The GeForce 6800 XT having 3 better shader performance is not particularly notable, as altogether the Radeon X1550 performs better when taking into account other relevant data.

The Radeon X1550 requires 27 Watts to run but there is no entry for the GeForce 6800 XT. We would recommend a PSU with at least 420 Watts for the Radeon X1550.

GPU Mini Review

Mini ReviewRadeon X1550 is an entry-level GPU based on the 80nm variant of the R500 architecture.
It's based on the RV516 Core and offers 4 Pixel Shaders, 4 TMUs and 4 ROPs, on a 128-bit of standard DDR. The central unit runs at 550MHz and the memory clock operates at up to 400MHz.
It's therefore an underclocked Radeon X1300 PRO (although a 600MHz version is also available and will offer identical performance) with Crossfire support. As it's not based on a Shader-Unified architecture, both DirectX 10 & 11 games aren't supported.
The groundbreaking new NVIDIA GeForce 6800 graphics processing units (GPUs) and their revolutionary technologies power worlds where reality and fantasy meet; worlds in which new standards are set for visual realism and quality, performance, and video functionality. The GeForce 6800 GPUs deliver powerful, elegant graphics to drench your senses, immersing you in unparalleled worlds of visual effects for the ultimate PC experience.
