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 6750 Gigabyte OC 1GB Edition.

The R9 270X has a 360 MHz higher core clock speed and 44 more Texture Mapping Units than the HD 6750. This results in the R9 270X providing 61.4 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 360 MHz higher core clock speed and 16 more Render Output Units than the HD 6750. This results in the R9 270X providing 23.4 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 a year more recently than the HD 6750, and so the R9 270X is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 6750.

The R9 270X has 1024 MB more video memory than the HD 6750, 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 115.2 GB/sec greater memory bandwidth than the HD 6750, which means that the memory performance of the R9 270X is massively better than the HD 6750.

The Radeon HD 6750 Gigabyte OC 1GB Edition has 720 Shader Processing Units and the Radeon R9 270X Sapphire Toxic 2GB OC Edition has 1280. However, the actual shader performance of the HD 6750 is 266 and the actual shader performance of the R9 270X is 1251. The R9 270X having 985 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 HD 6750.

The R9 270X transistor size technology is 12 nm (nanometers) smaller than the HD 6750. This means that the R9 270X is expected to run slightly cooler and achieve higher clock frequencies than the HD 6750.

The Radeon HD 6750 Gigabyte OC 1GB Edition requires 86 Watts to run and the Radeon R9 270X Sapphire Toxic 2GB OC Edition requires 180 Watts. We would recommend a PSU with at least 450 Watts for the HD 6750 and a PSU with at least 500 Watts for the R9 270X. The R9 270X requires 94 Watts more than the HD 6750 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 HD 6750.

GPU Mini Review

Mini ReviewOverview
Radeon HD 6750 Gigabyte OC 1GB Edition is a special edition of AMD's fast-middle-class Radeon HD 6750, created by Sapphire. It features a new Cooling Solution and overclocking out of the box. Read below to know more.

Overclock Out of The Box
The Central Unit now runs at 740MHz, instead of 700MHz while the Memory Clock now operates at 1200MHz.

Cooling Solution
The reference AMD Single-Fan Cooling System has been replaced by Gigabyte's custom-designed 80mm Cooler. This means the card runs cooler under load.

Performance
Benchmarks indicate a 5% performance over the reference Radeon HD 6750.
Radeon 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.
