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.

The R9 270X has a 317 MHz higher core clock speed and 48 more Texture Mapping Units than the GeForce GTS 450. This results in the R9 270X providing 62.9 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 317 MHz higher core clock speed and 16 more Render Output Units than the GeForce GTS 450. This results in the R9 270X providing 22.7 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 GeForce 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 GeForce GTS 450 when running the latest games.

The R9 270X has 1024 MB more video memory than the GeForce 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 134.3 GB/sec greater memory bandwidth than the GeForce GTS 450, which means that the memory performance of the R9 270X is massively better than the GeForce GTS 450.

The Radeon R9 270X Sapphire Toxic 2GB OC Edition has 1280 Shader Processing Units and the GeForce GTS 450 has 192. However, the actual shader performance of the R9 270X is 1251 and the actual shader performance of the GeForce GTS 450 is 301. The R9 270X having 950 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 GeForce GTS 450.

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

The Radeon R9 270X Sapphire Toxic 2GB OC Edition requires 180 Watts to run and the GeForce GTS 450 requires 106 Watts. We would recommend a PSU with at least 500 Watts for the R9 270X and a PSU with at least 400 Watts for the GeForce GTS 450. The R9 270X requires 74 Watts more than the GeForce 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 GeForce GTS 450.

GPU Mini Review

Mini ReviewRadeon 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.
GeForce GTS 450 is a fast-middle-class Graphics Card based on the first revision of the Fermi Architecture.

The Fermi Architecture is manufactured with a 40nm technology and uses a technique known as Hot Clocking: The Shaders are clocked twice as fast as the Central Unit. While this leads to a reasonable performance boost, it causes enormous amounts of energy dissipation, leading, ultimately, to a significantly higher operating temperature.
Fermi is also the first GPU architecture with fully cached memory access which increases memory performance.

It equips a GPU Codenamed GF106-250-KA-A1 which has 4 Stream Multiprocessors activated and thus offers 192 Shader Processing Units, 32 TMUs and 16 ROPs. The Central Unit is clocked at 783MHz.

The GPU accesses a 1GB frame buffer of fast GDDR5, through a 128-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 902MHz.

DirectX 11.0 Support (11.0 Hardware Default) and support for SLI, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies.

Cooling Solution
The Cooling Solution consists of a Single-Fan.

Power Consumption
With a rated board TDP of 106W, it requires at least a 400W PSU and an available 6-pin connector.

Gaming benchmarks put its performance considerably above Radeon HD 6670.

System Suggestions
We recommend a decent processor (Intel Core i3) and 4GB of RAM for a system with GeForce GTS 450.
