Compare any two graphics cards:
GeForce GTS 450 1GB vs GeForce GTX 275
IntroThe GeForce GTS 450 1GB comes with a GPU clock speed of 783 MHz, and the 1024 MB of GDDR5 memory runs at 902 MHz through a 128-bit bus. It also is made up of 192 Stream Processors, 32 Texture Address Units, and 16 Raster Operation Units.Compare those specifications to the GeForce GTX 275, which has core speeds of 633 MHz on the GPU, and 1134 MHz on the 896 MB of GDDR3 memory. It features 240 SPUs as well as 80 Texture Address Units and 28 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 275 should perform much faster than the GeForce GTS 450 1GB overall. (explain)
Texel RateThe GeForce GTX 275 is quite a bit (approximately 102%) better at anisotropic filtering than the GeForce GTS 450 1GB. (explain)
Pixel RateThe GeForce GTX 275 will be much (about 41%) faster with regards to AA than the GeForce GTS 450 1GB, and also will be capable of handling higher screen resolutions without losing too much performance. (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 MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen 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 number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in a 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 - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
