In terms of overall gaming performance, the graphical capabilities of the AMD Radeon X1900 XT are very slightly better than the AMD Radeon HD 3800 series.

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 X1900 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 X1900 XT.

The HD 3800 has 256 MB more video memory than the Radeon X1900 XT, so is likely to be slightly better at displaying game textures at higher resolutions. However, overall, the Radeon X1900 XT has superior memory performance.

The Radeon X1900 XT has 46.4 GB/sec greater memory bandwidth than the HD 3800, which means that the memory performance of the Radeon X1900 XT is noticeably better than the HD 3800.

The Radeon X1900 XT has 48 Shader Processing Units and the Radeon HD 3800 series has 320. However, the actual shader performance of the Radeon X1900 XT is 20 and the actual shader performance of the HD 3800 is 0. The Radeon X1900 XT having 20 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon X1900 XT delivers a noticeably smoother and more efficient experience when processing graphical data than the HD 3800.

The Radeon X1900 XT requires 100 Watts to run but there is no entry for the Radeon HD 3800 series.

GPU Mini Review

Mini ReviewRadeon X1900 XT is a high-end GPU based on the 90nm variant of the R500 architecture.
It's based on the R580 Core and offers 48 Pixel Shaders, 16 TMUs and 16 ROPs, on a 256-bit of standard GDDR3. The central unit runs at 625MHz and the memory clock operates at up to 725MHz.
Its much faster than Radeon X1900 GT due to the core configuration.
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.
