Welcome to MersenneForum

My bad, I meant ~100 core-days, i.e. 2400 core-hours, which makes for a smaller discrepancy

Indeed, Benjamin "FloppusMaximus" Moody, in the United-TI posts that he removed after receiving TI's illegal DMCA takedown requests, estimated his solo factorization of the 512-bit RSA public key for TI-83+ OS signature checking to the equivalent of ~73 full-time calendar days, on a dual-core Athlon 64 computer.
So I estimated that newer micro-architectures, and the polynomials selected by msieve (which yield more relations per time unit than those generated by pol51, which Benjamin Moody, and we at RSALS, used in 2009), should reduce the amount of work around 100 core-days.
