Game GeForce GTX 780 EVGA Dual Classified w/ ACX Edition Radeon R9 270X Sapphire Dual-X 4GB OC Edition

In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 780 EVGA Dual Classified w/ ACX Edition are significantly better than the AMD Radeon R9 270X Sapphire Dual-X 4GB OC Edition.

The R9 270X has a 27 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 109.1 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 27 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 15.1 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 GTX 780, 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 R9 270X has 1024 MB more video memory than the GTX 780, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GTX 780 has superior memory performance.

The GTX 780 has 109.2 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 EVGA Dual Classified w/ ACX Edition has 2304 Shader Processing Units and the Radeon R9 270X Sapphire Dual-X 4GB OC Edition has 1280. However, the actual shader performance of the GTX 780 is 2410 and the actual shader performance of the R9 270X is 1164. The GTX 780 having 1246 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 EVGA Dual Classified w/ ACX Edition requires 250 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 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 ReviewGeForce GTX 780 EVGA Dual Classified w/ ACX Edition is a special edition of the high-end GeForce GTX 780.
This edition comes with a custom double fan cooling solution and with a special PCB which together allow a reasonable performance boost from the start, as GeForce GTX 780 benefits from the GPU Boost 2.0 technology.
Also, it has been overclocked out of the box from 863MHz to 993MHz while its boost clock is now of 1046MHz. The memory clock was left untouched.
Benchmarks indicate a 10% performance boost when compared to the reference card and so this edition performs slightly better than GeForce GTX Titan.
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"
