Compare any two graphics cards:
GeForce GTS 450 vs Radeon HD 5670
IntroThe GeForce GTS 450 features core clock speeds of 783 MHz on the GPU, and 902 MHz on the 512 MB of GDDR5 RAM. It features 192 SPUs along with 32 TAUs and 16 Rasterization Operator Units.Compare those specifications to the Radeon HD 5670, which comes with a GPU core clock speed of 775 MHz, and 1024 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also is made up of 400(80x5) Stream Processors, 20 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 5670 should be just a bit faster than the GeForce GTS 450 overall. (explain)
Texel RateThe GeForce GTS 450 should be quite a bit (approximately 62%) better at AF than the Radeon HD 5670. (explain)
Pixel RateThe GeForce GTS 450 is a lot (more or less 102%) faster with regards to full screen anti-aliasing than the Radeon HD 5670, and will be able to handle higher resolutions better. (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 max amount of information (measured in megabytes per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
