Compare any two graphics cards:
GeForce 8600 GT 256MB GDDR3 vs GeForce GT 315
IntroThe GeForce 8600 GT 256MB GDDR3 has a clock speed of 540 MHz and a GDDR3 memory frequency of 700 MHz. It also uses a 128-bit bus, and makes use of a 80 nm design. It is comprised of 32 SPUs, 16 Texture Address Units, and 8 ROPs.Compare those specifications to the GeForce GT 315, which features GPU core speed of 625 MHz, and 512 MB of DDR3 memory set to run at 790 MHz through a 128-bit bus. It also is comprised of 48 Stream Processors, 16 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GT 315 should perform a small bit faster than the GeForce 8600 GT 256MB GDDR3 in general. (explain)
Texel RateThe GeForce GT 315 should be a bit (more or less 16%) better at texture filtering than the GeForce 8600 GT 256MB GDDR3. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GT 315 is a better choice, though only just barely. (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 max amount of data (counted in megabytes per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many 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.
