Compare any two graphics cards:
GeForce RTX 3070 Ti vs GeForce RTX 3080 Ti
IntroThe GeForce RTX 3070 Ti makes use of a 8 nm design. nVidia has set the core frequency at 1575 MHz. The GDDR6X RAM runs at a speed of 1188 MHz on this particular model. It features 6144 SPUs along with 192 Texture Address Units and 96 ROPs.
Compare that to the GeForce RTX 3080 Ti, which has GPU clock speed of 1365 MHz, and 12288 MB of GDDR6X memory running at 1188 MHz through a 384-bit bus. It also is made up of 10240 Stream Processors, 320 TAUs, and 112 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce RTX 3080 Ti should be a lot faster than the GeForce RTX 3070 Ti overall. (explain)
Texel RateThe GeForce RTX 3080 Ti will be quite a bit (about 44%) better at anisotropic filtering than the GeForce RTX 3070 Ti. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce RTX 3080 Ti is the winner, but not 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 max amount of information (counted in megabytes per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. 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 lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
