Compare any two graphics cards:
GeForce GTS 450 vs Radeon HD 6570 (OEM) 2GB
IntroThe GeForce GTS 450 has clock speeds of 783 MHz on the GPU, and 902 MHz on the 512 MB of GDDR5 RAM. It features 192 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.Compare that to the Radeon HD 6570 (OEM) 2GB, which comes with GPU clock speed of 650 MHz, and 1024 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also features 480 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 6570 (OEM) 2GB should in theory be a little bit superior to the GeForce GTS 450 in general. (explain)
Texel RateThe GeForce GTS 450 will be a lot (more or less 61%) faster with regards to AF than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTS 450 is superior to the Radeon HD 6570 (OEM) 2GB, by a large margin. (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: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
