Compare any two graphics cards:
GeForce GT 230 vs GeForce GTS 450
IntroThe GeForce GT 230 comes with a core clock speed of 550 MHz and a DDR3 memory frequency of 800 MHz. It also uses a 192-bit bus, and makes use of a 40 nm design. It is comprised of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.Compare all of that to the GeForce GTS 450, which comes with clock speeds of 783 MHz on the GPU, and 902 MHz on the 512 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 BandwidthIn theory, the GeForce GTS 450 will be 50% faster than the GeForce GT 230 overall, due to its higher data rate. (explain)
Texel RateThe GeForce GTS 450 will be much (approximately 185%) better at AF than the GeForce GT 230. (explain)
Pixel RateThe GeForce GTS 450 is much (approximately 185%) faster with regards to AA than the GeForce GT 230, and will be capable of handling higher 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 (counted in MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the 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 in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
