Compare any two graphics cards:
GeForce 9800 GT 1GB vs GeForce GTS 450
IntroThe GeForce 9800 GT 1GB uses a 65/55 nm design. nVidia has set the core frequency at 600 MHz. The GDDR3 memory is set to run at a speed of 900 MHz on this specific model. It features 112 SPUs along with 56 TAUs and 16 ROPs.Compare that to the GeForce GTS 450, which features GPU core speed of 783 MHz, and 512 MB of GDDR5 memory running at 902 MHz through a 128-bit bus. It also features 192 Stream Processors, 32 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTS 450 should theoretically be just a bit superior to the GeForce 9800 GT 1GB overall. (explain)
Texel RateThe GeForce 9800 GT 1GB will be much (approximately 34%) faster with regards to AF than the GeForce GTS 450. (explain)
Pixel RateThe GeForce GTS 450 is much (more or less 31%) faster with regards to AA than the GeForce 9800 GT 1GB, and also will be able to handle higher screen 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 largest amount of data (in units of MB per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 are applied per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number 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 rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
