Game GeForce 8800 GTS EVGA SSC 640MB Edition Radeon R9 270X Sapphire Dual-X 4GB OC Edition

In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 270X Sapphire Dual-X 4GB OC Edition are massively better than the Nvidia GeForce 8800 GTS EVGA SSC 640MB Edition.

The R9 270X has a 444 MHz higher core clock speed and 56 more Texture Mapping Units than the 8800 GTS. This results in the R9 270X providing 67.8 GTexel/s better texturing performance. 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 444 MHz higher core clock speed and 12 more Render Output Units than the 8800 GTS. This results in the R9 270X providing 21.1 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The R9 270X was released over three years more recently than the 8800 GTS, and so the R9 270X is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the 8800 GTS when running the latest games.

The R9 270X has 3456 MB more video memory than the 8800 GTS, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the R9 270X also has superior memory performance overall.

The R9 270X has 107.2 GB/sec greater memory bandwidth than the 8800 GTS, which means that the memory performance of the R9 270X is massively better than the 8800 GTS.

The GeForce 8800 GTS EVGA SSC 640MB Edition has 96 Shader Processing Units and the Radeon R9 270X Sapphire Dual-X 4GB OC Edition has 1280. However, the actual shader performance of the 8800 GTS is 138 and the actual shader performance of the R9 270X is 1164. The R9 270X having 1026 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 270X delivers a massively smoother and more efficient experience when processing graphical data than the 8800 GTS.

The R9 270X transistor size technology is 62 nm (nanometers) smaller than the 8800 GTS. This means that the R9 270X is expected to run massively cooler and achieve higher clock frequencies than the 8800 GTS.

The GeForce 8800 GTS EVGA SSC 640MB Edition requires 143 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 400 Watts for the 8800 GTS and a PSU with at least 500 Watts for the R9 270X. The R9 270X requires 37 Watts more than the 8800 GTS to run. The difference is significant enough that the R9 270X may have a slight adverse affect on your yearly electricity bills in comparison to the 8800 GTS.

GPU Mini Review

Mini ReviewOverview
GeForce 8800 GTS EVGA SSC 640MB Edition is a special edition of NVIDIA's Performance GeForce 8800 GTS 640MB, created by EVGA.

Overclock: Central Unit
The Central Unit now runs at 576MHz, instead of 513MHz.

Overclock: Memory Clock
The Operating Memory Clock is now of 900MHz while the Frame Buffer remains the same.

Cooling Solution
The Cooling System remains the same.

Performance
Benchmarks indicate a 7% performance over the reference GeForce 8800 GTS 640MB.
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"
