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 4860.

The R9 270X has a 400 MHz higher core clock speed and 48 more Texture Mapping Units than the Radeon HD 4860. This results in the R9 270X providing 65.6 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 R9 270X has a 400 MHz higher core clock speed and 16 more Render Output Units than the Radeon HD 4860. This results in the R9 270X providing 24 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 4860, 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 4860 when running the latest games.

The R9 270X has 1536 MB more video memory than the Radeon HD 4860, 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 96 GB/sec greater memory bandwidth than the Radeon HD 4860, which means that the memory performance of the R9 270X is massively better than the Radeon HD 4860.

The Radeon R9 270X Sapphire Toxic 2GB OC Edition has 1280 Shader Processing Units and the Radeon HD 4860 has 640. However, the actual shader performance of the R9 270X is 1251 and the actual shader performance of the Radeon HD 4860 is 291. The R9 270X having 960 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 4860.

The R9 270X transistor size technology is 27 nm (nanometers) smaller than the Radeon HD 4860. This means that the R9 270X is expected to run slightly cooler and achieve higher clock frequencies than the Radeon HD 4860.

The Radeon R9 270X Sapphire Toxic 2GB OC Edition requires 180 Watts to run and the Radeon HD 4860 requires 130 Watts. We would recommend a PSU with at least 500 Watts for the R9 270X. The R9 270X requires 50 Watts more than the Radeon HD 4860 to run. The difference is significant enough that the R9 270X may have a slight adverse affect on your yearly electricity bills in comparison to the Radeon HD 4860.

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 4860 is a high-end GPU based on the 55nm, third unified shader architecture, R700.
It's based on the RV790 GT Core (related to Radeon HD 4830) and offers 640 Shader Processing Units, 32 TMUs and 16 ROPs a 256-bit memory interface of fast GDDR5. The central unit runs at 700MHz and the memory clock runs at up to 750MHz.
It's expected to perform only slightly better than Radeon HD 4850 as it comes higher clocked and paired with fast GDDR5 but features less Shading Units and less TMUs. It should perform considerably better at higher resolutions but overall, expect only a 2-3% performance boost compared to Radeon HD 4850.
Some of today's modern games should run fluently at high settings but with modest resolutions. DirectX 11 games aren't supported.
