Thread: Spectre/Meltdown patch a prob?
Post: Spectre/Meltdown patch a prob?
Did a quick search and came up blank.
But does the Spectre/meltdown patches effect cracking speeds?
I've heard performance hits all over the place (5%-30%)
Ubuntu server 16.04.4 lts

Thread: FPGA cards?
Post: FPGA cards?
Ok so now that hashcat supports FPGAs that have CL drivers, are there any PCIe cards that actually run with it?
Are they on par H/s per $ as a standard GPU?s |
