Compare any two graphics cards:
GeForce GTS 250 1GB vs Radeon HD 4670 512MB
IntroThe GeForce GTS 250 1GB comes with a clock speed of 738 MHz and a GDDR3 memory frequency of 1100 MHz. It also features a 256-bit memory bus, and makes use of a 65/55 nm design. It is comprised of 128 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.Compare those specs to the Radeon HD 4670 512MB, which has clock speeds of 750 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR4/GDDR3/DDR3/DDR2 memory. It features 320(64x5) SPUs as well as 32 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTS 250 1GB, in theory, should be much faster than the Radeon HD 4670 512MB overall. (explain)
Texel RateThe GeForce GTS 250 1GB should be much (about 97%) faster with regards to anisotropic filtering than the Radeon HD 4670 512MB. (explain)
Pixel RateThe GeForce GTS 250 1GB should be much (more or less 97%) better at FSAA than the Radeon HD 4670 512MB, and also should be capable of handling higher screen 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 data (measured in megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed 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 better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. 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 lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
