Compare any two graphics cards:
GeForce GTX 580 vs GeForce GTX 650 Ti
IntroThe GeForce GTX 580 features a GPU core speed of 772 MHz, and the 1536 MB of GDDR5 memory is set to run at 1002 MHz through a 384-bit bus. It also features 512 Stream Processors, 64 Texture Address Units, and 48 ROPs.
Compare all of that to the GeForce GTX 650 Ti, which features GPU clock speed of 928 MHz, and 1024 MB of GDDR5 RAM running at 1350 MHz through a 128-bit bus. It also is made up of 768 SPUs, 64 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 580 should in theory be quite a bit superior to the GeForce GTX 650 Ti in general. (explain)
Texel RateThe GeForce GTX 650 Ti will be a small bit (about 20%) more effective at anisotropic filtering than the GeForce GTX 580. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 580 is the winner, 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.
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 largest amount of data (in units of megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 are applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
