Compare any two graphics cards:
GeForce GT 450 (OEM) vs GeForce GTX 460 1GB
IntroThe GeForce GT 450 (OEM) makes use of a 40 nm design. nVidia has clocked the core frequency at 790 MHz. The GDDR5 RAM is set to run at a frequency of 1000 MHz on this particular card. It features 144 SPUs along with 24 TAUs and 24 Rasterization Operator Units.Compare those specs to the GeForce GTX 460 1GB, which comes with a core clock speed of 675 MHz and a GDDR5 memory speed of 900 MHz. It also uses a 256-bit memory bus, and makes use of a 40 nm design. It is comprised of 336 SPUs, 56 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 460 1GB is 20% faster than the GeForce GT 450 (OEM) in general, because of its higher bandwidth. (explain)
Texel RateThe GeForce GTX 460 1GB should be a lot (more or less 99%) better at AF than the GeForce GT 450 (OEM). (explain)
Pixel RateThe GeForce GTX 460 1GB is a bit (about 14%) more effective at FSAA than the GeForce GT 450 (OEM), and also will be 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.

Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock 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 rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
