Compare any two graphics cards:
GeForce 8600 GT 512MB GDDR3 vs GeForce GT 240 GDDR5 1GB
IntroThe GeForce 8600 GT 512MB GDDR3 has a GPU core speed of 540 MHz, and the 512 MB of GDDR3 RAM is set to run at 700 MHz through a 128-bit bus. It also features 32 Stream Processors, 16 Texture Address Units, and 8 Raster Operation Units.Compare all of that to the GeForce GT 240 GDDR5 1GB, which has GPU clock speed of 550 MHz, and 1024 MB of GDDR5 RAM set to run at 850 MHz through a 128-bit bus. It also is comprised of 96 Stream Processors, 32 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GT 240 GDDR5 1GB should perform quite a bit faster than the GeForce 8600 GT 512MB GDDR3 in general. (explain)
Texel RateThe GeForce GT 240 GDDR5 1GB should be much (more or less 104%) more effective at anisotropic filtering than the GeForce 8600 GT 512MB GDDR3. (explain)
Pixel RateThe GeForce GT 240 GDDR5 1GB is a small bit (approximately 2%) faster with regards to AA than the GeForce 8600 GT 512MB GDDR3, and also capable of handling higher screen resolutions without losing too much performance. (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 maximum amount of data (in units of MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better 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 are applied in one second. This is calculated by multiplying the total amount of texture units by the core clock 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 processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
