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

The GTX 770 has a 29 MHz higher core clock speed than the R9 290, but the R9 290 has 32 more Texture Mapping Units than the GTX 770. As a result, the R9 290 exhibits a 29.2 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 29 MHz higher core clock speed than the R9 290, but the R9 290 has 32 more Render Output Units than the GTX 770. As a result, the R9 290 exhibits a 32 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 290 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 290 Sapphire Vapor-X OC Edition and the GeForce GTX 770 PNY Enthusiast 4GB OC 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 290 has 134 GB/sec greater memory bandwidth than the GTX 770, which means that the memory performance of the R9 290 is massively better than the GTX 770.

The Radeon R9 290 Sapphire Vapor-X OC Edition has 2560 Shader Processing Units and the GeForce GTX 770 PNY Enthusiast 4GB OC Edition has 1536. However, the actual shader performance of the R9 290 is 2241 and the actual shader performance of the GTX 770 is 1706. The R9 290 having 535 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 290 delivers a massively smoother and more efficient experience when processing graphical data than the GTX 770.

The Radeon R9 290 Sapphire Vapor-X OC Edition requires 275 Watts to run and the GeForce GTX 770 PNY Enthusiast 4GB OC Edition requires 230 Watts. We would recommend a PSU with at least 750 Watts for the R9 290 and a PSU with at least 600 Watts for the GTX 770. The R9 290 requires 45 Watts more than the GTX 770 to run. The difference is significant enough that the R9 290 may have a slight adverse affect on your yearly electricity bills in comparison to the GTX 770.

GPU Mini Review

Mini ReviewRadeon R9 290 Sapphire Vapor-X OC Edition is a special edition of the high-end Radeon R9 290.
This edition comes overclocked out of the box in the central unit which was increased from 947MHz to 1030MHz and in the memory clock which now operates at 1400MHz. Furthermore, the card comes with a custom triple fan solution which will reduce its temperature under load.
Benchmarks indicate a 3% performance boost over the reference card.
GeForce GTX 770 PNY Enthusiast 4GB OC Edition is a special edition of GeForce GTX 770.
This edition comes with a custom dual 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 1059MHz while its boost clock is now of 1111MHz and its frame buffer was doubled to 4GB, which will prove useless. The memory clock was left untouched.
Benchmarks indicate a 4% performance boost when compared to the reference card.
