Game Radeon R9 270X Sapphire Dual-X 4GB OC Edition GeForce GTX Titan

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

The R9 270X has a 183 MHz higher core clock speed than the GeForce GTX Titan, but the GeForce GTX Titan has 144 more Texture Mapping Units than the R9 270X. As a result, the GeForce GTX Titan exhibits a 105.9 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 183 MHz higher core clock speed than the GeForce GTX Titan, but the GeForce GTX Titan has 16 more Render Output Units than the R9 270X. As a result, the GeForce GTX Titan exhibits a 7.6 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 270X was released less than a year after the GeForce GTX Titan, 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 GeForce GTX Titan has 2048 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 GeForce GTX Titan also has superior memory performance overall.

The GeForce GTX Titan has 109.2 GB/sec greater memory bandwidth than the R9 270X, which means that the memory performance of the GeForce GTX Titan is massively better than the R9 270X.

The Radeon R9 270X Sapphire Dual-X 4GB OC Edition has 1280 Shader Processing Units and the GeForce GTX Titan has 2688. However, the actual shader performance of the R9 270X is 1164 and the actual shader performance of the GeForce GTX Titan is 2355. The GeForce GTX Titan having 1191 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX Titan delivers a massively smoother and more efficient experience when processing graphical data than the R9 270X.

The Radeon R9 270X Sapphire Dual-X 4GB OC Edition requires 180 Watts to run and the GeForce GTX Titan requires 250 Watts. We would recommend a PSU with at least 500 Watts for the R9 270X and a PSU with at least 600 Watts for the GeForce GTX Titan. The GeForce GTX Titan requires 70 Watts more than the R9 270X to run. The difference is significant enough that the GeForce GTX Titan may have an adverse affect on your yearly electricity bills in comparison to the R9 270X.

GPU Mini Review

Mini ReviewRadeon 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"
GeForce GTX Titan (can also be addressed as GeForce GTX 685) is a high end GFX based on the 28nm Kepler architecture.
It's based on the Kepler GK110 Core used on the Tesla K20 Workstation, but with only 14 SMX activated and so it features 2688 Shader Processing Units, 48 ROPs and 224 TMUs on a 384-bit interface of fast GDDR5. The central clock runs at 837MHz and goes up to 876MHz in Turbo Mode, while the memory clock operates at 1502MHz. GeForce GTX Titan will draw no more than 250 Watts.
GeForce GTX Titan's biggest feature is the Kepler GPU Boost 2.0 which raises the GPU's central unit and Shaders speeds to a frequency even higher to the one the Turbo Boost allows, if the GPU's temperature and Voltage allows it.
Benchmarks indicate its performance is up to 30% better than GeForce GTX 680 and up to 10% worse than GeForce GTX 690. Therefore, even the most demanding games will run at the highest settings, using a 2560x1600 resolution.
