Game Radeon R9 290 Asus DirectCU II OC Edition Radeon R9 270X Sapphire Dual-X 4GB OC Edition

In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 290 Asus DirectCU II OC Edition are significantly better than the AMD Radeon R9 270X Sapphire Dual-X 4GB OC Edition.

The R9 270X has a 20 MHz higher core clock speed than the R9 290, but the R9 290 has 80 more Texture Mapping Units than the R9 270X. As a result, the R9 290 exhibits a 78.4 GTexel/s better Texture Fill Rate than the R9 270X. 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 20 MHz higher core clock speed than the R9 290, but the R9 290 has 32 more Render Output Units than the R9 270X. As a result, the R9 290 exhibits a 31.4 GPixel/s better Pixel Fill Rate than the R9 270X. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The R9 290 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 Radeon R9 290 Asus DirectCU II OC Edition and the Radeon R9 270X Sapphire Dual-X 4GB OC Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The R9 290 has 140.8 GB/sec greater memory bandwidth than the R9 270X, which means that the memory performance of the R9 290 is massively better than the R9 270X.

The Radeon R9 290 Asus DirectCU II OC Edition 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 290 is 2176 and the actual shader performance of the R9 270X is 1164. The R9 290 having 1012 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 290 delivers a massively smoother and more efficient experience when processing graphical data than the R9 270X.

The Radeon R9 290 Asus DirectCU II OC Edition requires 275 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 290 and a PSU with at least 500 Watts for the R9 270X. The R9 290 requires 95 Watts more than the R9 270X to run. The difference is significant enough that the R9 290 may have an adverse affect on your yearly electricity bills in comparison to the R9 270X.

GPU Mini Review

Mini ReviewRadeon R9 290 Asus DirectCU II OC Edition is a special edition of the high-end Radeon R9 290.
This edition comes overclocked out of the box in the central unit which was increased from 947MHz to 1000MHz. The memory clock was left untouched. Furthermore, the card comes with a custom cooling solution which will reduce its temperature under load.
Benchmarks indicate a 2% performance boost over the reference card.
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"
