Compare any two graphics cards:
GeForce 8600 GT 512MB GDDR3 vs GeForce GTX 650
IntroThe GeForce 8600 GT 512MB GDDR3 features clock speeds of 540 MHz on the GPU, and 700 MHz on the 512 MB of GDDR3 memory. It features 32 SPUs as well as 16 TAUs and 8 Rasterization Operator Units.Compare those specifications to the GeForce GTX 650, which uses a 28 nm design. nVidia has clocked the core speed at 1058 MHz. The GDDR5 RAM runs at a frequency of 1250 MHz on this card. It features 384 SPUs along with 32 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 650 should perform much faster than the GeForce 8600 GT 512MB GDDR3 in general. (explain)
Texel RateThe GeForce GTX 650 will be quite a bit (more or less 292%) better at texture filtering than the GeForce 8600 GT 512MB GDDR3. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 650 is the winner, by a large margin. (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 largest amount of data (in units of megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
