In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 3850 AGP are significantly better than the AMD Radeon X1900 GT Rev. 2.
The HD 3850 was released over a year more recently than the X1900 GT, 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 X1900 GT.
The HD 3850 has 256 MB more video memory than the X1900 GT, so is likely to be slightly better at displaying game textures at higher resolutions. This is supported by the fact that the HD 3850 also has superior memory performance overall.
The HD 3850 has 10.9 GB/sec greater memory bandwidth than the X1900 GT, which means that the memory performance of the HD 3850 is slightly better than the X1900 GT.
The Radeon X1900 GT Rev. 2 has 36 Shader Processing Units and the Radeon HD 3850 AGP has 320. However, the actual shader performance of the X1900 GT is 12 and the actual shader performance of the HD 3850 is 214. The HD 3850 having 202 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 X1900 GT.
The Radeon X1900 GT Rev. 2 requires 75 Watts to run and the Radeon HD 3850 AGP requires 75 Watts. We would recommend a PSU with at least 450 Watts for the HD 3850, but we do not have a recommended PSU wattage for the X1900 GT. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

Mini Review | Radeon X1900 GT Rev. 2 is a variant of the Radeon X1900 GT that comes with a slightly higher operating memory clock (660MHz VS 600 MHz) but also with its central unit underclocked (512MHz VS 575MHz). Unfortunately, its performance ends up being worse than the first variant since this GPU does not benefit from extra memory bandwidth and falls behind previous in series Radeon X1800 XT. | Radeon 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. |
