Compare any two graphics cards:
GeForce 8600 GT 1GB GDDR3 vs GeForce GT 450 (OEM)
IntroThe GeForce 8600 GT 1GB GDDR3 has a GPU clock speed of 540 MHz, and the 1024 MB of GDDR3 memory is set to run at 700 MHz through a 128-bit bus. It also features 32 SPUs, 16 TAUs, and 8 ROPs.Compare all of that to the GeForce GT 450 (OEM), which has a clock speed of 790 MHz and a GDDR5 memory frequency of 1000 MHz. It also features a 192-bit memory bus, and makes use of a 40 nm design. It is comprised of 144 SPUs, 24 TAUs, and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GT 450 (OEM) should perform a lot faster than the GeForce 8600 GT 1GB GDDR3 overall. (explain)
Texel RateThe GeForce GT 450 (OEM) should be much (about 119%) faster with regards to AF than the GeForce 8600 GT 1GB GDDR3. (explain)
Pixel RateThe GeForce GT 450 (OEM) should be a lot (about 339%) better at FSAA than the GeForce 8600 GT 1GB GDDR3, and also capable of handling higher resolutions while still performing well. (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 data (in units of MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units 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 the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
