In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 3800 series are significantly better than the AMD Radeon X1800 XT.

The HD 3800 has no core clock speed set, so any comparison between Texture and Pixel Fill Rates is not currently possible.

The HD 3800 was released over a year more recently than the Radeon X1800 XT, and so the HD 3800 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Radeon X1800 XT.

The Radeon X1800 XT and the Radeon HD 3800 series have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The Radeon X1800 XT has 44.8 GB/sec greater memory bandwidth than the HD 3800, which means that the memory performance of the Radeon X1800 XT is noticeably better than the HD 3800.

The Radeon X1800 XT has 16 Shader Processing Units and the Radeon HD 3800 series has 320. However, the actual shader performance of the Radeon X1800 XT is 6 and the actual shader performance of the HD 3800 is 0. The Radeon X1800 XT having 6 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon X1800 XT delivers a noticeably smoother and more efficient experience when processing graphical data than the HD 3800.

The Radeon X1800 XT requires 113 Watts to run but there is no entry for the Radeon HD 3800 series.

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.
Radeon HD 3800 Series is not a GPU but instead a combination between Radeon HD 3830, Radeon HD 3850 and Radeon HD 3870 whose rank is a balance between the three and that exists for System Requirements purposes only.
