In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 5670 Gigabyte 1GB OC Edition are noticeably better than the AMD Radeon HD 3850 AGP.

The HD 5670 has a 282 MHz higher core clock speed and 4 more Texture Mapping Units than the HD 3850. This results in the HD 5670 providing 8.3 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 5670 has a 282 MHz higher core clock speed than the HD 3850, but the HD 3850 has 8 more Render Output Units than the HD 5670. As a result, the HD 3850 exhibits a 3.1 GPixel/s better Pixel Fill Rate than the HD 5670. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 5670 was released over a year more recently than the HD 3850, and so the HD 5670 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 3850.

The HD 5670 has 512 MB more video memory than the HD 3850, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 5670 also has superior memory performance overall.

The HD 5670 has 10.9 GB/sec greater memory bandwidth than the HD 3850, which means that the memory performance of the HD 5670 is slightly better than the HD 3850.

The Radeon HD 5670 Gigabyte 1GB OC Edition has 400 Shader Processing Units and the Radeon HD 3850 AGP has 320. However, the actual shader performance of the HD 5670 is 190 and the actual shader performance of the HD 3850 is 214. The HD 3850 having 24 better shader performance is not particularly notable, as altogether the HD 5670 performs better when taking into account other relevant data.

The HD 5670 transistor size technology is 15 nm (nanometers) smaller than the HD 3850. This means that the HD 5670 is expected to run slightly cooler and achieve higher clock frequencies than the HD 3850.

The Radeon HD 3850 AGP requires 75 Watts to run but there is no entry for the HD 5670. 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 HD 5670.

GPU Mini Review

Mini ReviewRadeon HD 5670 Gigabyte 1GB OC Edition is a special edition of the middle-class Radeon HD 5670.
This edition features a new cooling system and overclocking out of the box in the core-clock from 775MHz to 950MHz.
There are no benchmarks available and so this GPU's rank is predicted.
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.
