Compare any two graphics cards:
GeForce GTS 450 vs Radeon HD 4850 1GB
IntroThe GeForce GTS 450 comes with a GPU core clock speed of 783 MHz, and the 512 MB of GDDR5 memory is set to run at 902 MHz through a 128-bit bus. It also is made up of 192 Stream Processors, 32 TAUs, and 16 ROPs.Compare those specs to the Radeon HD 4850 1GB, which comes with a GPU core clock speed of 625 MHz, and 1024 MB of GDDR4 memory set to run at 993 MHz through a 256-bit bus. It also is made up of 800(160x5) Stream Processors, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 4850 1GB should be a small bit faster than the GeForce GTS 450 overall. (explain)
Texel RateThe GeForce GTS 450 is a bit (more or less 0%) better at texture filtering than the Radeon HD 4850 1GB. (explain)
Pixel RateThe GeForce GTS 450 should be much (more or less 25%) more effective at full screen anti-aliasing than the Radeon HD 4850 1GB, and also will be capable of handling higher 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: Bandwidth is the maximum amount of information (measured in MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling 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 the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
