In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 780 Asus Strix OC 6GB Edition are significantly better than the AMD Radeon R9 270X Sapphire Toxic 2GB OC Edition.

The R9 270X has a 211 MHz higher core clock speed than the GTX 780, but the GTX 780 has 112 more Texture Mapping Units than the R9 270X. As a result, the GTX 780 exhibits a 82.7 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 211 MHz higher core clock speed than the GTX 780, but the GTX 780 has 16 more Render Output Units than the R9 270X. As a result, the GTX 780 exhibits a 7.5 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 GTX 780 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 GTX 780 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 GTX 780 also has superior memory performance overall.

The GTX 780 has 96.4 GB/sec greater memory bandwidth than the R9 270X, which means that the memory performance of the GTX 780 is massively better than the R9 270X.

The GeForce GTX 780 Asus Strix OC 6GB Edition has 2304 Shader Processing Units and the Radeon R9 270X Sapphire Toxic 2GB OC Edition has 1280. However, the actual shader performance of the GTX 780 is 2168 and the actual shader performance of the R9 270X is 1251. The GTX 780 having 917 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 780 delivers a massively smoother and more efficient experience when processing graphical data than the R9 270X.

The GeForce GTX 780 Asus Strix OC 6GB Edition requires 250 Watts to run and the Radeon R9 270X Sapphire Toxic 2GB OC Edition requires 180 Watts. We would recommend a PSU with at least 600 Watts for the GTX 780 and a PSU with at least 500 Watts for the R9 270X. The GTX 780 requires 70 Watts more than the R9 270X to run. The difference is significant enough that the GTX 780 may have an adverse affect on your yearly electricity bills in comparison to the R9 270X.

GPU Mini Review

Mini ReviewOverview
GeForce GTX 780 Asus Strix OC 6GB Edition is a special edition of NVIDIA's High-End GeForce GTX 780 6GB, created by Asus.

Overclock: Central Unit
The Central Unit now runs at 889MHz, instead of 863MHz and goes up to 941MHz, in Turbo Mode.

Overclock: Memory Clock
The Operating Memory Clock and the Frame Buffer remain the same.

Cooling Solution
The reference NVIDIA Single-Fan Cooling System has been replaced by Asus's DirectCU II cooling technology which outperforms reference designs with an exclusive 10mm heatpipe that transports 40% more heat away from the GPU.

Performance
Benchmarks indicate a 2% performance over the reference GeForce GTX 780 6GB.
Radeon R9 270X Sapphire Toxic 2GB OC Edition is a special edition of the high-end Radeon R9 270X.
This edition comes with a custom cooling system called "Tri-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 1100MHz, while the Boost clock is now of 1150MHz. Also, the operating memory clock is now of 1500MHz.
Benchmarks indicate a 5% performance boost over the standard edition and so this card will surpass a Radeon HD 7950.
