Compare any two graphics cards:
GeForce GT 450 (OEM) vs GeForce GTX 460 2GB
IntroThe GeForce GT 450 (OEM) uses a 40 nm design. nVidia has set the core speed at 790 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this particular card. It features 144 SPUs as well as 24 Texture Address Units and 24 ROPs.Compare all of that to the GeForce GTX 460 2GB, which makes use of a 40 nm design. nVidia has clocked the core speed at 675 MHz. The GDDR5 RAM works at a frequency of 900 MHz on this specific model. It features 336 SPUs along with 56 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 460 2GB should theoretically be a little bit better than the GeForce GT 450 (OEM) overall. (explain)
Texel RateThe GeForce GTX 460 2GB should be quite a bit (approximately 99%) faster with regards to texture filtering than the GeForce GT 450 (OEM). (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 460 2GB is a better choice, but only just. (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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock 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 applied per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
