Compare any two graphics cards:
GeForce GTS 250 1GB vs Radeon HD 4850 512MB
IntroThe GeForce GTS 250 1GB features a GPU clock speed of 738 MHz, and the 1024 MB of GDDR3 memory runs at 1100 MHz through a 256-bit bus. It also is made up of 128 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.Compare all of that to the Radeon HD 4850 512MB, which comes with a GPU core clock speed of 625 MHz, and 512 MB of GDDR3 memory running at 993 MHz through a 256-bit bus. It also is comprised of 800(160x5) Stream Processors, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTS 250 1GB should in theory be a small bit better than the Radeon HD 4850 512MB overall. (explain)
Texel RateThe GeForce GTS 250 1GB will be quite a bit (about 89%) more effective at anisotropic filtering than the Radeon HD 4850 512MB. (explain)
Pixel RateThe GeForce GTS 250 1GB should be a small bit (about 18%) faster with regards to FSAA than the Radeon HD 4850 512MB, and also will be capable of handling 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: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
