In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 270X Sapphire Toxic 2GB OC Edition are massively better than the AMD Radeon HD 4850.

The R9 270X has a 475 MHz higher core clock speed and 40 more Texture Mapping Units than the Radeon HD 4850. This results in the R9 270X providing 63 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 R9 270X has a 475 MHz higher core clock speed and 16 more Render Output Units than the Radeon HD 4850. This results in the R9 270X providing 25.2 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 R9 270X was released over three years more recently than the Radeon HD 4850, and so the R9 270X 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 R9 270X has 1536 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 R9 270X also has superior memory performance overall.

The R9 270X has 128.4 GB/sec greater memory bandwidth than the Radeon HD 4850, which means that the memory performance of the R9 270X is massively better than the Radeon HD 4850.

The Radeon R9 270X Sapphire Toxic 2GB OC Edition has 1280 Shader Processing Units and the Radeon HD 4850 has 800. However, the actual shader performance of the R9 270X is 1251 and the actual shader performance of the Radeon HD 4850 is 350. The R9 270X having 901 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 270X delivers a massively smoother and more efficient experience when processing graphical data than the Radeon HD 4850.

The R9 270X transistor size technology is 27 nm (nanometers) smaller than the Radeon HD 4850. This means that the R9 270X is expected to run slightly cooler and achieve higher clock frequencies than the Radeon HD 4850.

The Radeon R9 270X Sapphire Toxic 2GB OC Edition requires 180 Watts to run and the Radeon HD 4850 requires 110 Watts. We would recommend a PSU with at least 500 Watts for the R9 270X and a PSU with at least 450 Watts for the Radeon HD 4850. The R9 270X requires 70 Watts more than the Radeon HD 4850 to run. The difference is significant enough that the R9 270X may have an adverse affect on your yearly electricity bills in comparison to the Radeon HD 4850.

GPU Mini Review

Mini ReviewRadeon R9 270X Sapphire Toxic 2GB OC Edition is a special edition of the high-end Radeon R9 270X.
This edition comes with a custom cooling system called "Tri-X", which reduces the card's temperature under load, significantly and comes overclocked out of the box in the central unit that was increased from 1000MHz to 1100MHz, while the Boost clock is now of 1150MHz. Also, the operating memory clock is now of 1500MHz.
Benchmarks indicate a 5% performance boost over the standard edition and so this card will surpass a Radeon HD 7950.
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.
