Compare any two graphics cards:
GeForce GTX 285 2GB vs GeForce GTX 650
IntroThe GeForce GTX 285 2GB uses a 55 nm design. nVidia has clocked the core speed at 648 MHz. The GDDR3 memory runs at a frequency of 1242 MHz on this model. It features 240 SPUs along with 80 TAUs and 32 ROPs.Compare those specs to the GeForce GTX 650, which features a core clock speed of 1058 MHz and a GDDR5 memory frequency of 1250 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is made up of 384 SPUs, 32 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 285 2GB should theoretically be a lot faster than the GeForce GTX 650 overall. (explain)
Texel RateThe GeForce GTX 285 2GB will be much (approximately 53%) faster with regards to AF than the GeForce GTX 650. (explain)
Pixel RateThe GeForce GTX 285 2GB is quite a bit (approximately 22%) better at AA than the GeForce GTX 650, 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: Memory bandwidth is the max amount of data (in units of MB per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This 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 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 number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few 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.
