Compare any two graphics cards:
GeForce 8800 Ultra vs GeForce GTX 650
IntroThe GeForce 8800 Ultra comes with a GPU core speed of 612 MHz, and the 768 MB of GDDR3 memory is set to run at 1080 MHz through a 384-bit bus. It also is comprised of 128 SPUs, 64 Texture Address Units, and 24 Raster Operation Units.Compare those specs to the GeForce GTX 650, which uses a 28 nm design. nVidia has set the core speed at 1058 MHz. The GDDR5 memory is set to run at a speed of 1250 MHz on this particular model. It features 384 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce 8800 Ultra should perform much faster than the GeForce GTX 650 overall. (explain)
Texel RateThe GeForce 8800 Ultra should be a bit (more or less 16%) better at texture filtering than the GeForce GTX 650. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 650 is a better choice, though not by far. (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 information (counted in MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core 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 also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
