Compare any two graphics cards:
GeForce GT 450 (OEM) vs GeForce GTX 260
IntroThe GeForce GT 450 (OEM) comes with core clock speeds of 790 MHz on the GPU, and 1000 MHz on the 1536 MB of GDDR5 RAM. It features 144 SPUs as well as 24 Texture Address Units and 24 Rasterization Operator Units.Compare those specifications to the GeForce GTX 260, which uses a 65 nm design. nVidia has clocked the core frequency at 576 MHz. The GDDR3 RAM runs at a frequency of 999 MHz on this particular card. It features 192 SPUs along with 64 Texture Address Units and 28 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GTX 260 should perform just a bit faster than the GeForce GT 450 (OEM) overall. (explain)
Texel RateThe GeForce GTX 260 is a lot (approximately 94%) better at texture filtering than the GeForce GT 450 (OEM). (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GT 450 (OEM) is the winner, 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

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses 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 amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of 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 processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs 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 fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
