In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 270X Sapphire Toxic 2GB OC Edition are massively better than the Nvidia GeForce GTS 450 Asus DirectCU OC 1GB Edition.

The R9 270X has a 250 MHz higher core clock speed and 48 more Texture Mapping Units than the GTS 450. This results in the R9 270X providing 60.8 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 250 MHz higher core clock speed and 16 more Render Output Units than the GTS 450. This results in the R9 270X providing 21.6 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 GTS 450, 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 GTS 450 when running the latest games.

The R9 270X has 1024 MB more video memory than the GTS 450, 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 131.2 GB/sec greater memory bandwidth than the GTS 450, which means that the memory performance of the R9 270X is massively better than the GTS 450.

The GeForce GTS 450 Asus DirectCU OC 1GB Edition has 192 Shader Processing Units and the Radeon R9 270X Sapphire Toxic 2GB OC Edition has 1280. However, the actual shader performance of the GTS 450 is 326 and the actual shader performance of the R9 270X is 1251. The R9 270X having 925 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 GTS 450.

The R9 270X transistor size technology is 12 nm (nanometers) smaller than the GTS 450. This means that the R9 270X is expected to run slightly cooler and achieve higher clock frequencies than the GTS 450.

The GeForce GTS 450 Asus DirectCU OC 1GB Edition requires 106 Watts to run and the Radeon R9 270X Sapphire Toxic 2GB OC Edition requires 180 Watts. We would recommend a PSU with at least 400 Watts for the GTS 450 and a PSU with at least 500 Watts for the R9 270X. The R9 270X requires 74 Watts more than the GTS 450 to run. The difference is significant enough that the R9 270X may have an adverse affect on your yearly electricity bills in comparison to the GTS 450.

GPU Mini Review

Mini ReviewOverview
GeForce GTS 450 Asus DirectCU OC 1GB Edition is a special edition of NVIDIA's fast-middle-class GeForce GTS 450, created by Asus.

Overclock Out of The Box
The Central Unit is now of 850MHz, instead of 783MHz while the Operating Memory Clock was increased to 950MHz.

Cooling Solution
The Cooling System was replaced by Asus's DirectCU Thermal Solution which is 20% cooler and 35% quieter.

Performance
Benchmarks indicate a 8% performance boost over the reference GeForce GTS 450.
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.
