Compare any two graphics cards:
GeForce 9800 GT 512MB vs GeForce GTS 450 1GB
IntroThe GeForce 9800 GT 512MB comes with a core clock frequency of 600 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 256-bit memory bus, and makes use of a 65/55 nm design. It is made up of 112 SPUs, 56 TAUs, and 16 Raster Operation Units.Compare all of that 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 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTS 450 1GB should in theory be a bit faster than the GeForce 9800 GT 512MB in general. (explain)
Texel RateThe GeForce 9800 GT 512MB should be quite a bit (about 34%) faster with regards to AF than the GeForce GTS 450 1GB. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTS 450 1GB is the winner, by far. (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 maximum amount of data (counted in MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once 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 AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock 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 rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
