Compare any two graphics cards:
GeForce GTS 450 vs GeForce GTX 580
IntroThe GeForce GTS 450 uses a 40 nm design. nVidia has clocked the core frequency at 783 MHz. The GDDR5 RAM runs at a speed of 902 MHz on this card. It features 192 SPUs along with 32 TAUs and 16 ROPs.Compare those specs to the GeForce GTX 580, which features core clock speeds of 772 MHz on the GPU, and 1002 MHz on the 1536 MB of GDDR5 memory. It features 512 SPUs along with 64 Texture Address Units and 48 Rasterization Operator Units.

3DMark Fire Strike Graphics Score
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 580 will be 233% faster than the GeForce GTS 450 in general, because of its higher data rate. (explain)
Texel RateThe GeForce GTX 580 is much (more or less 97%) faster with regards to texture filtering than the GeForce GTS 450. (explain)
Pixel RateThe GeForce GTX 580 should be a lot (about 196%) more effective at FSAA than the GeForce GTS 450, and should be capable of handling higher 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: Memory bandwidth is the largest amount of data (in units of MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, 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 texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core 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 fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
