Gaming Performance Comparison

In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 290X Sapphire Tri-X OC Edition are noticeably better than the Nvidia GeForce GTX 770 WindForce 3X OC 4GB Edition.

The GTX 770 has a 97 MHz higher core clock speed than the R9 290X, but the R9 290X has 48 more Texture Mapping Units than the GTX 770. As a result, the R9 290X exhibits a 37.5 GTexel/s better Texture Fill Rate than the GTX 770. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 770 has a 97 MHz higher core clock speed than the R9 290X, but the R9 290X has 32 more Render Output Units than the GTX 770. As a result, the R9 290X exhibits a 30.2 GPixel/s better Pixel Fill Rate than the GTX 770. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The R9 290X was released less than a year after the GTX 770, 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 Radeon R9 290X Sapphire Tri-X OC Edition and the GeForce GTX 770 WindForce 3X OC 4GB Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The R9 290X has 108.5 GB/sec greater memory bandwidth than the GTX 770, which means that the memory performance of the R9 290X is massively better than the GTX 770.

The Radeon R9 290X Sapphire Tri-X OC Edition has 2816 Shader Processing Units and the GeForce GTX 770 WindForce 3X OC 4GB Edition has 1536. However, the actual shader performance of the R9 290X is 2534.4. The R9 290X having 998.4 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 290X delivers a massively smoother and more efficient experience when processing graphical data than the GTX 770.

The Radeon R9 290X Sapphire Tri-X OC Edition requires 290 Watts to run but there is no entry for the GeForce GTX 770 WindForce 3X OC 4GB Edition. We would recommend a PSU with at least 750 Watts for the R9 290X and a PSU with at least 550 Watts for the GTX 770. The R9 290X has been recommended a PSU with 200 Watts more than the GTX 770. The difference is significant enough that the R9 290X may have an adverse affect on your yearly electricity bills in comparison to the GTX 770.

GPU Mini Review

Mini ReviewRadeon R9 290X Sapphire Tri-X OC Edition is a special edition of the high-end Radeon R9 290X.
This edition comes overclocked out of the box in the central unit which was increased from 1000MHz to 1040MHz and in the memory clock which now operates at 1300MHz. Furthermore, the card comes with a custom triple fan solution which will reduce its temperature under load.
There are no benchmarks available but expect, at most, a 2% performance boost over the reference card.
GeForce GTX 770 WindForce 3X OC 4GB Edition is a special edition of the high-end GeForce GTX 770.
This edition comes with a custom triple fan cooling solution which by itself should allow a slight performance boost, as GeForce GTX 770 benefits from the GPU Boost 2.0 technology.
Also, it has been overclocked out of the box from 1046MHz to 1137MHz while its boost clock is now of 1189MHz. he memory clock was left untouched and the frame buffer was doubled to 4GB. However, this card cannot benefit from that much video memory and so it offers no performance boost. This edition performs like the 2GB one Gigabyte offers.
Benchmarks indicate a 6% performance boost when compared to the reference card and so this edition performs very slightly better than GeForce GTX 590.
