Compare any two graphics cards:
GeForce 9800 GT 512MB vs GeForce GTS 450
IntroThe GeForce 9800 GT 512MB uses a 65/55 nm design. nVidia has set the core speed at 600 MHz. The GDDR3 RAM is set to run at a frequency of 900 MHz on this particular model. It features 112 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.Compare those specifications to the GeForce GTS 450, which makes use of a 40 nm design. nVidia has set the core speed at 783 MHz. The GDDR5 memory runs at a frequency of 902 MHz on this card. 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 BandwidthAs far as performance goes, the GeForce GTS 450 should in theory be a bit superior to the GeForce 9800 GT 512MB in general. (explain)
Texel RateThe GeForce 9800 GT 512MB should be quite a bit (approximately 34%) faster with regards to anisotropic filtering than the GeForce GTS 450. (explain)
Pixel RateThe GeForce GTS 450 is much (approximately 31%) better at FSAA than the GeForce 9800 GT 512MB, and will be able to handle higher resolutions while still performing well. (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 data (counted in megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. 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 are applied per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
