In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 3850 AGP are noticeably better than the AMD Radeon X1950 Pro.

The HD 3850 was released over a year more recently than the Radeon X1950 Pro, and so the HD 3850 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Radeon X1950 Pro.

The Radeon HD 3850 AGP and the Radeon X1950 Pro have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The HD 3850 has 8.9 GB/sec greater memory bandwidth than the Radeon X1950 Pro, which means that the memory performance of the HD 3850 is marginally better than the Radeon X1950 Pro.

The Radeon HD 3850 AGP has 320 Shader Processing Units and the Radeon X1950 Pro has 36. However, the actual shader performance of the HD 3850 is 214 and the actual shader performance of the Radeon X1950 Pro is 13. The HD 3850 having 201 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 3850 delivers a slightly smoother and more efficient experience when processing graphical data than the Radeon X1950 Pro.

The Radeon HD 3850 AGP requires 75 Watts to run and the Radeon X1950 Pro requires 66 Watts. We would recommend a PSU with at least 450 Watts for the HD 3850 and a PSU with at least 420 Watts for the Radeon X1950 Pro. The HD 3850 requires 9 Watts more than the Radeon X1950 Pro to run. The difference is not significant enough for the HD 3850 to have a noticeably larger impact on your yearly electricity bills than the Radeon X1950 Pro.

GPU Mini Review

Mini ReviewRadeon HD 3850 AGP is a variant of the high-end Radeon HD 3850 based on the 55nm, second unified shader architecture, R600. Check its page to know more about its Core.
Compared to Radeon HD 3850, it features twice as much video memory and an AGP 8X Bus Interface. Benchmarks indicate the double sized frame buffer benefits this GPU largely and so its performance is up to 8% better than the reference Radeon HD 3850.
Today's modern games should run fluently at medium settings but with modest resolutions. DirectX 11 games aren't supported.
Radeon X1950 Pro is a high-end GPU based on the 80nm variant of the R500 architecture.
It's based on the R570 Core and offers 36 Pixel Shaders, 12 TMUs and 12 ROPs, on a 256-bit of standard GDDR3. The central unit runs at 575MHz and the memory clock operates at up to 690MHz.
Its therefore a an overclocked Radeon X1950 GT and should perform slightly better.
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.
