Compare any two graphics cards:
GeForce 9500 GT 1GB GDDR3 vs GeForce GTS 450
IntroThe GeForce 9500 GT 1GB GDDR3 has a GPU core speed of 550 MHz, and the 1024 MB of GDDR3 memory is set to run at 800 MHz through a 128-bit bus. It also is made up of 32 Stream Processors, 16 TAUs, and 8 Raster Operation Units.Compare that to the GeForce GTS 450, which uses a 40 nm design. nVidia has clocked the core speed at 783 MHz. The GDDR5 memory runs at a frequency of 902 MHz on this particular model. It features 192 SPUs along with 32 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTS 450 should be 126% quicker than the GeForce 9500 GT 1GB GDDR3 overall, because of its greater bandwidth. (explain)
Texel RateThe GeForce GTS 450 will be quite a bit (approximately 185%) more effective at AF than the GeForce 9500 GT 1GB GDDR3. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTS 450 is a better choice, 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 largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could 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 Raster Operations Pipelines by the the core speed of the card. 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 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.
