Game Radeon R9 270X Gigabyte 4GB OC Edition Crossfire Radeon R9 270X Sapphire Dual-X 4GB OC Edition

In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 270X Gigabyte 4GB OC Edition Crossfire are significantly better than the AMD Radeon R9 270X Sapphire Dual-X 4GB OC Edition.

The R9 270X has a 30 MHz higher core clock speed and 80 more Texture Mapping Units than the R9 270X. This results in the R9 270X providing 86.4 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 30 MHz higher core clock speed and 32 more Render Output Units than the R9 270X. This results in the R9 270X providing 34.6 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 less than a year after the R9 270X, and so they are likely to have similar driver support for optimizing performance when running the latest games.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The R9 270X has 4096 MB more video memory than the R9 270X, 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 179.2 GB/sec greater memory bandwidth than the R9 270X, which means that the memory performance of the R9 270X is massively better than the R9 270X.

The Radeon R9 270X Gigabyte 4GB OC Edition Crossfire has 2560 Shader Processing Units and the Radeon R9 270X Sapphire Dual-X 4GB OC Edition has 1280. However, the actual shader performance of the R9 270X is 2394 and the actual shader performance of the R9 270X is 1164. The R9 270X having 1230 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 R9 270X.

The Radeon R9 270X Gigabyte 4GB OC Edition Crossfire requires 180 Watts to run and the Radeon R9 270X Sapphire Dual-X 4GB OC Edition requires 180 Watts. We would recommend a PSU with at least 750 Watts for the R9 270X and a PSU with at least 500 Watts for the R9 270X. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

GPU Mini Review

Mini ReviewThis is the Crossfire setup of Radeon R9 270X Gigabyte 4GB OC Edition.Radeon R9 270X Sapphire Dual-X 4GB OC Edition is a special edition of the high-end Radeon R9 270X.
This edition comes with a custom cooling system called "Vapor-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 1020MHz, while the Boost clock is now of 1070MHz.
Furthermore, the card has twice as much memory when compared to the reference card. However, this card will not benefit from extra memory and thus such feature ends up being useless.
Expect little or no performance boost over the standard edition and exactly the same performance as "Radeon R9 270X Sapphire Dual-X 2GB OC Edition"
