Game GeForce GTX 950 Zotac OC 2GB Edition Radeon R9 270X Sapphire Dual-X 4GB OC Edition

In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 950 Zotac OC 2GB Edition are marginally better than the AMD Radeon R9 270X Sapphire Dual-X 4GB OC Edition.

The GTX 950 has a 82 MHz higher core clock speed than the R9 270X, but the R9 270X has 32 more Texture Mapping Units than the GTX 950. As a result, the R9 270X exhibits a 28.7 GTexel/s better Texture Fill Rate than the GTX 950. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 950 has a 82 MHz higher core clock speed than the R9 270X and the same number of Render Output Units. This results in the GTX 950 providing 2.7 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 GTX 950 was released over a year more recently than the R9 270X, and so the GTX 950 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the R9 270X.

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 2048 MB more video memory than the GTX 950, 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 70.3 GB/sec greater memory bandwidth than the GTX 950, which means that the memory performance of the R9 270X is much better than the GTX 950.

The GeForce GTX 950 Zotac OC 2GB Edition has 768 Shader Processing Units and the Radeon R9 270X Sapphire Dual-X 4GB OC Edition has 1280. However, the actual shader performance of the GTX 950 is 1326 and the actual shader performance of the R9 270X is 1164. The GTX 950 having 162 better shader performance is not particularly notable, as altogether the R9 270X performs better when taking into account other relevant data.

The GeForce GTX 950 Zotac OC 2GB Edition requires 120 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 350 Watts for the GTX 950 and a PSU with at least 500 Watts for the R9 270X. The R9 270X requires 60 Watts more than the GTX 950 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 GTX 950.

Benchmarks Indicate a 5% Performance Boost over the Reference GeForce GTX 950 2GB.
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"
