Compare any two graphics cards:
GeForce GTS 250 1GB vs GeForce GTX 570
IntroThe GeForce GTS 250 1GB has core clock speeds of 738 MHz on the GPU, and 1100 MHz on the 1024 MB of GDDR3 memory. It features 128 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.Compare those specs to the GeForce GTX 570, which comes with a clock speed of 732 MHz and a GDDR5 memory speed of 950 MHz. It also makes use of a 320-bit memory bus, and makes use of a 40 nm design. It is made up of 480 SPUs, 60 Texture Address Units, and 40 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GTX 570 should perform much faster than the GeForce GTS 250 1GB overall. (explain)
Texel RateThe GeForce GTS 250 1GB is just a bit (approximately 8%) more effective at AF than the GeForce GTX 570. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 570 is a better choice, by a large margin. (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 max amount of information (counted in megabytes per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels that 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 core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
