Compare any two graphics cards:
GeForce GT 450 (OEM) vs GeForce GTX 460
IntroThe GeForce GT 450 (OEM) has a GPU core clock speed of 790 MHz, and the 1536 MB of GDDR5 memory is set to run at 1000 MHz through a 192-bit bus. It also is made up of 144 Stream Processors, 24 TAUs, and 24 Raster Operation Units.Compare all that to the GeForce GTX 460, which features a clock speed of 675 MHz and a GDDR5 memory speed of 900 MHz. It also features a 192-bit memory bus, and uses a 40 nm design. It features 336 SPUs, 56 Texture Address Units, and 24 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GT 450 (OEM) should be a bit faster than the GeForce GTX 460 overall. (explain)
Texel RateThe GeForce GTX 460 will be quite a bit (about 99%) faster with regards to AF than the GeForce GT 450 (OEM). (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GT 450 (OEM) is a better choice, though only just barely. (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 max amount of information (in units of megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 can be applied in one second. This figure is worked out by multiplying the total texture units of the card 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 applied in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
