Compare any two graphics cards:
GeForce 8600 GT 512MB GDDR3 vs GeForce GT 315
IntroThe GeForce 8600 GT 512MB GDDR3 comes with a GPU clock speed of 540 MHz, and the 512 MB of GDDR3 memory is set to run at 700 MHz through a 128-bit bus. It also is comprised of 32 SPUs, 16 Texture Address Units, and 8 ROPs.Compare all of that to the GeForce GT 315, which features a core clock speed of 625 MHz and a DDR3 memory speed of 790 MHz. It also features a 128-bit memory bus, and uses a 40 nm design. It is made up of 48 SPUs, 16 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GT 315, in theory, should be a little bit faster than the GeForce 8600 GT 512MB GDDR3 in general. (explain)
Texel RateThe GeForce GT 315 is a small bit (approximately 16%) more effective at AF than the GeForce 8600 GT 512MB GDDR3. (explain)
Pixel RateThe GeForce GT 315 will be a little bit (about 16%) faster with regards to full screen anti-aliasing than the GeForce 8600 GT 512MB GDDR3, and will be able to handle higher screen 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: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs 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 output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
