Compare any two graphics cards:
GeForce GTS 450 vs Radeon HD 6670 (OEM) 1GB
IntroThe GeForce GTS 450 uses a 40 nm design. nVidia has set the core speed at 783 MHz. The GDDR5 RAM works at a frequency of 902 MHz on this specific card. It features 192 SPUs as well as 32 TAUs and 16 ROPs.Compare all that to the Radeon HD 6670 (OEM) 1GB, which has a GPU core clock speed of 800 MHz, and 1024 MB of GDDR5 RAM set to run at 1000 MHz through a 128-bit bus. It also is comprised of 480 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6670 (OEM) 1GB should in theory perform a bit faster than the GeForce GTS 450 overall. (explain)
Texel RateThe GeForce GTS 450 will be quite a bit (approximately 31%) more effective at texture filtering than the Radeon HD 6670 (OEM) 1GB. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTS 450 is a better choice, and very much so. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
