Compare any two graphics cards:
GeForce GTX 460 1GB vs GeForce GTX 660 Ti
IntroThe GeForce GTX 460 1GB features core speeds of 675 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR5 memory. It features 336 SPUs as well as 56 TAUs and 32 Rasterization Operator Units.
Compare all of that to the GeForce GTX 660 Ti, which comes with a clock frequency of 915 MHz and a GDDR5 memory speed of 1500 MHz. It also uses a 192-bit memory bus, and uses a 28 nm design. It features 1344 SPUs, 112 Texture Address Units, and 24 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 660 Ti should be much faster than the GeForce GTX 460 1GB overall. (explain)
Texel RateThe GeForce GTX 660 Ti is quite a bit (more or less 171%) better at AF than the GeForce GTX 460 1GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 660 Ti is superior to the GeForce GTX 460 1GB, though only just barely. (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 max amount of information (in units of MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
