Well, no luck with these, either. Here's an i7 right after running tune:
Code:
$ ./yafu
Applying tune_info entry for LINUX64 -         Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz


YAFU Version 2.07
Built with GCC 9
Using GMP-ECM 7.0.5-dev, Powered by GMP 6.2.0
Detected         Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz
Detected L1 = 32768 bytes, L2 = 8388608 bytes, CL = 64 bytes
Using 1 random witness for Rabin-Miller PRP checks
Cached 664579 primes; max prime is 9999991
