Compare any two graphics cards:
GeForce GT 450 (OEM) vs GeForce GTX 465
IntroThe GeForce GT 450 (OEM) features core 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 465, which comes with GPU clock speed of 607 MHz, and 1024 MB of GDDR5 memory set to run at 802 MHz through a 256-bit bus. It also is made up of 352 Stream Processors, 44 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 465 is 7% faster than the GeForce GT 450 (OEM) overall, due to its higher bandwidth. (explain)
Texel RateThe GeForce GTX 465 will be quite a bit (more or less 41%) more effective at texture filtering than the GeForce GT 450 (OEM). (explain)
Pixel RateThe GeForce GTX 465 should be just a bit (about 2%) faster with regards to full screen anti-aliasing than the GeForce GT 450 (OEM), and also able to handle higher screen 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If 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 are applied per second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at 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 card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to 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.
