Compare any two graphics cards:
GeForce GTS 450 1GB vs Radeon HD 5670
IntroThe GeForce GTS 450 1GB features a core clock frequency of 783 MHz and a GDDR5 memory speed of 902 MHz. It also features a 128-bit memory bus, and uses a 40 nm design. It is made up of 192 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.Compare those specifications to the Radeon HD 5670, which features a clock frequency of 775 MHz and a GDDR5 memory frequency of 1000 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It features 400(80x5) SPUs, 20 TAUs, and 8 Raster Operation Units.
Display Graphs
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 5670 should be 11% faster than the GeForce GTS 450 1GB in general, due to its higher bandwidth. (explain)
Texel RateThe GeForce GTS 450 1GB is a lot (more or less 62%) more effective at texture filtering than the Radeon HD 5670. (explain)
Pixel RateThe GeForce GTS 450 1GB should be much (about 102%) more effective at FSAA than the Radeon HD 5670, and should be capable of handling higher screen resolutions while still performing well. (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 max amount of information (measured in MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units of the card by the core 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 per second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core 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 output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
