Compare any two graphics cards:
GeForce GT 450 (OEM) vs GeForce GTX 460
IntroThe GeForce GT 450 (OEM) has a clock frequency of 790 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 192-bit bus, and makes use of a 40 nm design. It features 144 SPUs, 24 TAUs, and 24 ROPs.Compare those specs to the GeForce GTX 460, which features core speeds of 675 MHz on the GPU, and 900 MHz on the 768 MB of GDDR5 RAM. It features 336 SPUs as well as 56 Texture Address Units and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GT 450 (OEM) should theoretically be a little bit superior to the GeForce GTX 460 in general. (explain)
Texel RateThe GeForce GTX 460 will be a lot (about 99%) better at texture filtering than the GeForce GT 450 (OEM). (explain)
Pixel RateThe GeForce GT 450 (OEM) should be a little bit (about 17%) better at AA than the GeForce GTX 460, and should be capable of handling higher screen resolutions more effectively. (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 (measured in megabytes per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 can be applied per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. 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 is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
