Compare any two graphics cards:
GeForce GTX 570 vs GeForce GTX 650 Ti 2GB
IntroThe GeForce GTX 570 makes use of a 40 nm design. nVidia has clocked the core speed at 732 MHz. The GDDR5 RAM runs at a speed of 950 MHz on this model. It features 480 SPUs along with 60 Texture Address Units and 40 ROPs.
Compare all that to the GeForce GTX 650 Ti 2GB, which comes with a GPU core clock speed of 928 MHz, and 2048 MB of GDDR5 RAM running at 1350 MHz through a 128-bit bus. It also is comprised of 768 SPUs, 64 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 570 should in theory be quite a bit superior to the GeForce GTX 650 Ti 2GB overall. (explain)
Texel RateThe GeForce GTX 650 Ti 2GB should be a lot (approximately 35%) more effective at AF than the GeForce GTX 570. (explain)
Pixel RateThe GeForce GTX 570 should be much (about 97%) better at full screen anti-aliasing than the GeForce GTX 650 Ti 2GB, and able to handle higher screen resolutions while still performing well. (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: Bandwidth is the largest amount of information (in units of MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 can be applied in one second. This is calculated by multiplying the total texture units 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 applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The number 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 drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
