Compare any two graphics cards:
GeForce GT 450 (OEM) vs GeForce GTX 260 Core 216
IntroThe GeForce GT 450 (OEM) comes with clock speeds of 790 MHz on the GPU, and 1000 MHz on the 1536 MB of GDDR5 memory. It features 144 SPUs along with 24 TAUs and 24 ROPs.Compare all of that to the GeForce GTX 260 Core 216, which makes use of a 65 nm design. nVidia has clocked the core frequency at 576 MHz. The GDDR3 memory works at a frequency of 999 MHz on this particular card. It features 216 SPUs as well as 72 TAUs and 28 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 260 Core 216 should be just a bit faster than the GeForce GT 450 (OEM) in general. (explain)
Texel RateThe GeForce GTX 260 Core 216 should be quite a bit (more or less 119%) faster with regards to AF than the GeForce GT 450 (OEM). (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GT 450 (OEM) is the winner, 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 largest amount of information (in units of megabytes per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. 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 lots of 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.
