 standard version of the GeForce RTX 2060. -b 30 -t 512 -p 2400  620Mkey
 SUPER version of the GeForce RTX 2060.    -b 34 -t 512 -p 3000  765Mkey


Impressive performance for those RTX 2060 cards, i've just got my hands on a RTX 2080 card, but i can only squeeze approx 775 MKey/s out of it.
using -b 32 - t 512 - p 1630 (1018.0 MB) - this is just around the max of what i can do without getting out of memory errors.

As i have only 4GB of DDR4 ram in the rig used for bitcrack, i tried installing another 8GB block, which did not make any difference.
This machine is running windows 7 x64, maybe it will run better with windows 10? Smiley

Anyone else using RTX 2080 cards? please let me know how your performance is, if those 2060 cards does nearly the same im seriously thinking of swapping the 2080 card for maybe two of those instead.

you should use -b 46. since the card contains 46 SM Count
try -b 46 -t 512 -p 3000

Thanks for updating me on the matter of those SM counts, this is new to me, I have all the time concluded that the -b parameter should be used in parallel with ROP counts, but since -b 64 wasn't giving me the best performance i lowered it with /2 going with -b 32 then... great information, thanks Smiley

Now i managed to get approx 882 MKey/s with -b 46 -t 512 - p 950 this allocates 22.374.400 starting points (853 MB) which is close to the max for me, please let me know how it's possible to allocate more RAM on the card without memory error.
Once Bitcrack runs it shows 2349/8192MB used

EDIT: in parallel im also running another Bitcrack instance on this rig with an older GTX 770 card, allocating approx 390 MB in starting points, maybe I should try to benchmark the RTX 2080 without running the other card too Smiley

EDIT2: running with only one instance of Bitcrack, i can achieve 890 MKey/s with RTX 2080 using parameters: -b 46 - t 512 -t 1000
