Compare any two graphics cards:
GeForce GTS 150 vs GeForce GTX 580 3GB
IntroThe GeForce GTS 150 comes with a GPU core clock speed of 740 MHz, and the 1024 MB of GDDR3 memory is set to run at 500 MHz through a 256-bit bus. It also features 128 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.Compare those specs to the GeForce GTX 580 3GB, which comes with a GPU core clock speed of 772 MHz, and 3072 MB of GDDR5 memory running at 1002 MHz through a 384-bit bus. It also features 512 Stream Processors, 64 TAUs, and 48 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 580 3GB should be 501% quicker than the GeForce GTS 150 overall, due to its higher bandwidth. (explain)
Texel RateThe GeForce GTX 580 3GB should be a little bit (approximately 4%) better at anisotropic filtering than the GeForce GTS 150. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 580 3GB is the winner, 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: Bandwidth is the largest amount of data (in units of MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better 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 in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few 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.
