Compare any two graphics cards:
GeForce 8600 GT 1GB GDDR3 vs GeForce GTX 650
IntroThe GeForce 8600 GT 1GB GDDR3 features a clock speed of 540 MHz and a GDDR3 memory frequency of 700 MHz. It also makes use of a 128-bit memory bus, and makes use of a 80 nm design. It is made up of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.Compare those specs to the GeForce GTX 650, which uses a 28 nm design. nVidia has clocked the core frequency at 1058 MHz. The GDDR5 RAM works at a speed of 1250 MHz on this specific card. It features 384 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 650 should theoretically be quite a bit better than the GeForce 8600 GT 1GB GDDR3 in general. (explain)
Texel RateThe GeForce GTX 650 will be quite a bit (more or less 292%) faster with regards to AF than the GeForce 8600 GT 1GB GDDR3. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 650 is superior to the GeForce 8600 GT 1GB GDDR3, 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 max amount of data (counted in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the 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 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 video 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 most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
