Compare any two graphics cards:
GeForce 8800 GTS (G80) 320MB vs GeForce GTS 450 1GB
IntroThe GeForce 8800 GTS (G80) 320MB comes with a clock speed of 513 MHz and a GDDR3 memory frequency of 792 MHz. It also features a 320-bit memory bus, and makes use of a 90 nm design. It features 96 SPUs, 48 TAUs, and 20 ROPs.Compare those specs to the GeForce GTS 450 1GB, which comes with core speeds of 783 MHz on the GPU, and 902 MHz on the 1024 MB of GDDR5 memory. It features 192 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 8800 GTS (G80) 320MB should theoretically perform just a bit faster than the GeForce GTS 450 1GB in general. (explain)
Texel RateThe GeForce GTS 450 1GB should be a small bit (more or less 2%) better at AF than the GeForce 8800 GTS (G80) 320MB. (explain)
Pixel RateThe GeForce GTS 450 1GB will be quite a bit (more or less 22%) better at FSAA than the GeForce 8800 GTS (G80) 320MB, and capable of handling 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 largest amount of data (in units of MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. 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 number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better 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 in a second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
