Compare any two graphics cards:
GeForce GTS 250 1GB vs Radeon HD 5770
IntroThe GeForce GTS 250 1GB comes with a core clock speed of 738 MHz and a GDDR3 memory speed of 1100 MHz. It also makes use of a 256-bit bus, and makes use of a 65/55 nm design. It features 128 SPUs, 64 TAUs, and 16 ROPs.Compare all that to the Radeon HD 5770, which features a core clock speed of 850 MHz and a GDDR5 memory speed of 1200 MHz. It also features a 128-bit memory bus, and makes use of a 40 nm design. It features 800(160x5) SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon HD 5770 should perform a little bit faster than the GeForce GTS 250 1GB in general. (explain)
Texel RateThe GeForce GTS 250 1GB is a lot (approximately 39%) more effective at AF than the Radeon HD 5770. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon HD 5770 is a better choice, but only just. (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 data (in units of MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better 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 per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, 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 card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
