Compare any two graphics cards:
GeForce GT 450 (OEM) vs GeForce GTX 460 (OEM)
IntroThe GeForce GT 450 (OEM) comes with a GPU core clock speed of 790 MHz, and the 1536 MB of GDDR5 RAM is set to run at 1000 MHz through a 192-bit bus. It also is comprised of 144 Stream Processors, 24 TAUs, and 24 Raster Operation Units.Compare all that to the GeForce GTX 460 (OEM), which uses a 40 nm design. nVidia has clocked the core frequency at 650 MHz. The GDDR5 memory runs at a frequency of 850 MHz on this model. It features 336 SPUs along with 56 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GTX 460 (OEM) should be a bit faster than the GeForce GT 450 (OEM) in general. (explain)
Texel RateThe GeForce GTX 460 (OEM) is much (approximately 92%) better at anisotropic filtering than the GeForce GT 450 (OEM). (explain)
Pixel RateThe GeForce GTX 460 (OEM) will be a bit (approximately 10%) faster with regards to anti-aliasing than the GeForce GT 450 (OEM), and capable of handling higher resolutions better. (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 (measured in MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
