So iiuc for 25Mpix we have: [25*1024*1024] * 4 * 4 * 3 = 1258291200 byte = 1.171875 GB
And for 16MPix (my pana G7) we have: [16*1024*1024] * 4 * 4 * 3 = 805306368 bye = 0.75 GB Am I right? If yes, with 3GB I should be ok, at least till I upgrade my camera... >> Anyway, from here >> https://www.phoronix.com/scan.php?page=news_item&px=Darktable-27-Results >> I see that that almost all the cpus are slower than any gpu... >benchmarks always lie :) Always but phoronix :) Thankx, BW 2017-09-03 15:43 GMT+02:00 Roman Lebedev <[email protected]>: > On Sun, Sep 3, 2017 at 3:58 PM, Brune Wayce <[email protected]> wrote: > > I know that the 1060 would be a lot more better than the 1050ti, but it > is > > also too much expensive.
