Game Radeon R7 250 v2 XFX 2GB Edition Radeon R9 270X Sapphire Dual-X 4GB OC Edition

In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 270X Sapphire Dual-X 4GB OC Edition are massively better than the AMD Radeon R7 250 v2 XFX 2GB Edition.

The R9 270X has a 20 MHz higher core clock speed and 56 more Texture Mapping Units than the R7 250. This results in the R9 270X providing 57.6 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 20 MHz higher core clock speed and 24 more Render Output Units than the R7 250. This results in the R9 270X providing 24.6 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 R7 250 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.

The R9 270X has 2048 MB more video memory than the R7 250, 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 153.6 GB/sec greater memory bandwidth than the R7 250, which means that the memory performance of the R9 270X is massively better than the R7 250.

The Radeon R7 250 v2 XFX 2GB Edition has 384 Shader Processing Units and the Radeon R9 270X Sapphire Dual-X 4GB OC Edition has 1280. However, the actual shader performance of the R7 250 is 343 and the actual shader performance of the R9 270X is 1164. The R9 270X having 821 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 R7 250.

The Radeon R7 250 v2 XFX 2GB Edition requires 65 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 400 Watts for the R7 250 and a PSU with at least 500 Watts for the R9 270X. The R9 270X requires 115 Watts more than the R7 250 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 R7 250.

GPU Mini Review

Mini ReviewRadeon R7 250 v2 XFX 2GB Edition is a special edition of the middle-class Radeon R7 250 v2 2GB.

This edition is essentially a reference card with no overclock out of the box and thus there is no performance boost over the standard 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"
