Compare any two graphics cards:
GeForce 8800 GTS (G80) 320MB vs GeForce GTS 250 512MB
IntroThe GeForce 8800 GTS (G80) 320MB has a core clock speed of 513 MHz and a GDDR3 memory frequency of 792 MHz. It also makes use of a 320-bit memory bus, and uses a 90 nm design. It features 96 SPUs, 48 TAUs, and 20 Raster Operation Units.Compare those specs to the GeForce GTS 250 512MB, which makes use of a 65/55 nm design. nVidia has clocked the core frequency at 738 MHz. The GDDR3 RAM is set to run at a speed of 1100 MHz on this specific card. It features 128 SPUs as well as 64 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTS 250 512MB, in theory, should be a little bit faster than the GeForce 8800 GTS (G80) 320MB in general. (explain)
Texel RateThe GeForce GTS 250 512MB will be a lot (approximately 92%) more effective at texture filtering than the GeForce 8800 GTS (G80) 320MB. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTS 250 512MB is superior to the GeForce 8800 GTS (G80) 320MB, not by a very large margin though. (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 megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in one 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 outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
