Compare any two graphics cards:
GeForce GTX 570 vs GeForce GTX 650 Ti
IntroThe GeForce GTX 570 features core speeds of 732 MHz on the GPU, and 950 MHz on the 1280 MB of GDDR5 memory. It features 480 SPUs along with 60 TAUs and 40 Rasterization Operator Units.
Compare all that to the GeForce GTX 650 Ti, which uses a 28 nm design. nVidia has set the core frequency at 928 MHz. The GDDR5 RAM works at a frequency of 1350 MHz on this card. It features 768 SPUs along with 64 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 570 will be 76% quicker than the GeForce GTX 650 Ti overall, due to its greater data rate. (explain)
Texel RateThe GeForce GTX 650 Ti should be much (about 35%) more effective at anisotropic filtering than the GeForce GTX 570. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 570 is a better choice, 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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed 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 better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
