In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 4730 are noticeably better than the AMD Radeon HD 3850 AGP.

The HD 4730 has a 82 MHz higher core clock speed and 16 more Texture Mapping Units than the HD 3850. This results in the HD 4730 providing 13.3 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 4730 has a 82 MHz higher core clock speed than the HD 3850, but the HD 3850 has 8 more Render Output Units than the HD 4730. As a result, the HD 3850 exhibits a 4.7 GPixel/s better Pixel Fill Rate than the HD 4730. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 4730 was released over a year more recently than the HD 3850, and so the HD 4730 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 Radeon HD 4730 and the Radeon HD 3850 AGP have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The HD 4730 has 4.5 GB/sec greater memory bandwidth than the HD 3850, which means that the memory performance of the HD 4730 is marginally better than the HD 3850.

The Radeon HD 4730 has 640 Shader Processing Units and the Radeon HD 3850 AGP has 320. However, the actual shader performance of the HD 4730 is 312 and the actual shader performance of the HD 3850 is 214. The HD 4730 having 98 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 4730 delivers a marginally smoother and more efficient experience when processing graphical data than the HD 3850.

The Radeon HD 4730 requires 110 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 4730 and a PSU with at least 450 Watts for the HD 3850. The HD 4730 requires 35 Watts more than the HD 3850 to run. The difference is significant enough that the HD 4730 may have a slight adverse affect on your yearly electricity bills in comparison to the HD 3850.

GPU Mini Review

Mini ReviewRadeon HD 4730 is a fast-middle-class GPU based on the RV770 CE Core.
Just like Radeon HD 4770, it features 640 Shading Units, 32 TMUs but only 8 ROPs. The core and memory clocks are very similar.
Benchmarks indicate Radeon HD 4730's performance is about 20% than Radeon HD 4770 meaning it's still a very solid GPU, almost on level with acclaimed GeForce 9800 GT.
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.
