In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7750 Sapphire 1GB GDDR5 Edition are very slightly better than the AMD Radeon HD 4850.
The HD 7750 has a 175 MHz higher core clock speed but 8 fewer Texture Mapping Units than the Radeon HD 4850. The lower TMU count doesn't matter, though, as altogether the HD 7750 manages to provide 0.6 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 7750 has a 175 MHz higher core clock speed than the Radeon HD 4850 and the same number of Render Output Units. This results in the HD 7750 providing 2.8 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 7750 was released over three years more recently than the Radeon HD 4850, and so the HD 7750 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Radeon HD 4850 when running the latest games.
The HD 7750 has 512 MB more video memory than the Radeon HD 4850, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 7750 also has superior memory performance overall.
The HD 7750 has 8.4 GB/sec greater memory bandwidth than the Radeon HD 4850, which means that the memory performance of the HD 7750 is marginally better than the Radeon HD 4850.
The Radeon HD 4850 has 800 Shader Processing Units and the Radeon HD 7750 Sapphire 1GB GDDR5 Edition has 512. However, the actual shader performance of the Radeon HD 4850 is 350 and the actual shader performance of the HD 7750 is 348. The Radeon HD 4850 having 2 better shader performance is not particularly notable, as altogether the HD 7750 performs better when taking into account other relevant data.
The HD 7750 transistor size technology is 27 nm (nanometers) smaller than the Radeon HD 4850. This means that the HD 7750 is expected to run slightly cooler and achieve higher clock frequencies than the Radeon HD 4850.
The Radeon HD 4850 requires 110 Watts to run and the Radeon HD 7750 Sapphire 1GB GDDR5 Edition requires 55 Watts. We would recommend a PSU with at least 450 Watts for the Radeon HD 4850 and a PSU with at least 400 Watts for the HD 7750. The Radeon HD 4850 requires 55 Watts more than the HD 7750 to run. The difference is significant enough that the Radeon HD 4850 may have an adverse affect on your yearly electricity bills in comparison to the HD 7750.

|Mini Review||Radeon 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.
|Radeon HD 7750 Sapphire 1GB GDDR5 Edition is a special edition of Radeon HD 7750. |
The only new feature is a new cooling system which doesn't affect the performance directly and so its performance is on level with the standard version.
