Compare any two graphics cards:
GeForce 8600 GT 256MB DDR2 vs GeForce GT 450 (OEM)
IntroThe GeForce 8600 GT 256MB DDR2 comes with a core clock speed of 540 MHz and a DDR2 memory frequency of 400 MHz. It also makes use of a 128-bit bus, and uses a 80 nm design. It is comprised of 32 SPUs, 16 Texture Address Units, and 8 ROPs.Compare those specs to the GeForce GT 450 (OEM), which makes use of a 40 nm design. nVidia has set the core frequency at 790 MHz. The GDDR5 memory works at a speed of 1000 MHz on this specific model. It features 144 SPUs along with 24 TAUs and 24 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GT 450 (OEM) should in theory be much better than the GeForce 8600 GT 256MB DDR2 in general. (explain)
Texel RateThe GeForce GT 450 (OEM) will be much (about 119%) better at AF than the GeForce 8600 GT 256MB DDR2. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GT 450 (OEM) is a better choice, and very much so. (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 max amount of information (counted in megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
