Compare any two graphics cards:
GeForce GT 450 (OEM) vs GeForce GTX 460 2GB
IntroThe GeForce GT 450 (OEM) features a GPU core 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 features 144 Stream Processors, 24 TAUs, and 24 ROPs.Compare those specs to the GeForce GTX 460 2GB, which features core speeds of 675 MHz on the GPU, and 900 MHz on the 2048 MB of GDDR5 RAM. It features 336 SPUs along with 56 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 460 2GB will be 20% quicker than the GeForce GT 450 (OEM) overall, because of its greater data rate. (explain)
Texel RateThe GeForce GTX 460 2GB will be much (more or less 99%) better at AF than the GeForce GT 450 (OEM). (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 460 2GB is superior to the GeForce GT 450 (OEM), though not 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: Bandwidth is the max amount of data (measured in MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, 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 amount of 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 per second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
