Compare any two graphics cards:
GeForce 9500 GT 1GB GDDR3 vs GeForce GTS 450 1GB
IntroThe GeForce 9500 GT 1GB GDDR3 has a GPU clock speed of 550 MHz, and the 1024 MB of GDDR3 memory is set to run at 800 MHz through a 128-bit bus. It also is comprised of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.Compare those specifications to the GeForce GTS 450 1GB, which uses a 40 nm design. nVidia has set the core speed at 783 MHz. The GDDR5 memory works at a frequency of 902 MHz on this particular card. It features 192 SPUs as well as 32 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTS 450 1GB is 126% faster than the GeForce 9500 GT 1GB GDDR3 overall, because of its higher bandwidth. (explain)
Texel RateThe GeForce GTS 450 1GB will be much (approximately 185%) more effective at AF than the GeForce 9500 GT 1GB GDDR3. (explain)
Pixel RateThe GeForce GTS 450 1GB should be quite a bit (more or less 185%) more effective at AA than the GeForce 9500 GT 1GB GDDR3, and will be able to handle higher screen resolutions more effectively. (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 information (measured in MB per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling 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 card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
