In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7850 XFX Core Edition are massively better than the AMD Radeon HD 4730 .

The HD 7850 has a 110 MHz higher core clock speed and 32 more Texture Mapping Units than the HD 4730. This results in the HD 7850 providing 31 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 7850 has a 110 MHz higher core clock speed and 24 more Render Output Units than the HD 4730. This results in the HD 7850 providing 21.5 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 7850 was released over a year more recently than the HD 4730, and so the HD 7850 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 4730.

The HD 7850 has 512 MB more video memory than the HD 4730, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 7850 also has superior memory performance overall.

The HD 7850 has 102.4 GB/sec greater memory bandwidth than the HD 4730, which means that the memory performance of the HD 7850 is massively better than the HD 4730.

The Radeon HD 4730 has 640 Shader Processing Units and the Radeon HD 7850 XFX Core Edition has 1024. However, the actual shader performance of the HD 4730 is 312 and the actual shader performance of the HD 7850 is 749. The HD 7850 having 437 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7850 delivers a massively smoother and more efficient experience when processing graphical data than the HD 4730.

The HD 7850 transistor size technology is 27 nm (nanometers) smaller than the HD 4730. This means that the HD 7850 is expected to run slightly cooler and achieve higher clock frequencies than the HD 4730.

The Radeon HD 4730 requires 110 Watts to run but there is no entry for the Radeon HD 7850 XFX Core Edition. We would recommend a PSU with at least 450 Watts for the HD 4730 and a PSU with at least 500 Watts for the HD 7850. The HD 7850 has been recommended a PSU with 50 Watts more than the HD 4730. The difference is significant enough that the HD 7850 may have a slight adverse affect on your yearly electricity bills in comparison to the HD 4730.

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 7850 XFX Core Edition is a special edition of the powerful Radeon HD 7850. See the standard version for more information about it.
This edition features a special cooling system that allows twice as much heat dissipation when compared to the reference AMD cooling system but its performance is still the same, as there's no over-clocking out of the box.
