Gaming Performance Comparison

In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 4850 are massively better than the .

The has no core clock speed set, so any comparison between Texture and Pixel Fill Rates is not currently possible.

The Radeon HD 4850 was released over three years more recently than the , and so the Radeon HD 4850 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the when running the latest games.

The Radeon HD 4850 has 512 MB video memory, but the does not have an entry, so the two GPUs cannot be reliably compared in this area.

The Radeon HD 4850 has 800 Shader Processing Units but the does not have an entry, so the two GPUs cannot be reliably compared in this area.

The Radeon HD 4850 requires 110 Watts to run but there is no entry for the . We would recommend a PSU with at least 450 Watts for the Radeon HD 4850.

GPU Mini Review

Mini ReviewRadeon HD 4850 is a high-end GFX based on the 55nm, third unified shader architecture, R700.
It's based on the RV770 PRO Core and offers 800 Shader Processing Units, 40 TMUs and 16 ROPs a 256-bit memory interface of standard GDDR3. The central unit runs at 625MHz and the memory clock runs at up to 993MHz.
Some of today's modern games should run fluently at high settings but with modest resolutions. DirectX 11 games aren't supported.
