Compare any two graphics cards:
GeForce 9400 GT 256MB vs GeForce GTS 450 1GB
IntroThe GeForce 9400 GT 256MB comes with a core clock speed of 550 MHz and a GDDR2 memory speed of 400 MHz. It also uses a 128-bit bus, and uses a 65 nm design. It is made up of 16 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.Compare all that to the GeForce GTS 450 1GB, which comes with a clock frequency of 783 MHz and a GDDR5 memory speed of 902 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It is comprised of 192 SPUs, 32 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTS 450 1GB should in theory perform much faster than the GeForce 9400 GT 256MB in general. (explain)
Texel RateThe GeForce GTS 450 1GB is quite a bit (approximately 469%) faster with regards to anisotropic filtering than the GeForce 9400 GT 256MB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTS 450 1GB 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 maximum amount of data (counted in MB per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the 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 number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called 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 - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
