Compare any two graphics cards:
GeForce GTS 450 vs GeForce GTX 460
IntroThe GeForce GTS 450 has a core clock speed of 783 MHz and a GDDR5 memory frequency of 902 MHz. It also features a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 192 SPUs, 32 Texture Address Units, and 16 ROPs.
Compare those specs to the GeForce GTX 460, which makes use of a 40 nm design. nVidia has set the core frequency at 675 MHz. The GDDR5 memory is set to run at a frequency of 900 MHz on this card. It features 336 SPUs as well as 56 TAUs and 24 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 460 should perform quite a bit faster than the GeForce GTS 450 overall. (explain)
Texel RateThe GeForce GTX 460 should be much (approximately 51%) more effective at anisotropic filtering than the GeForce GTS 450. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 460 is superior to the GeForce GTS 450, and very much so. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 are applied in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card 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 card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
