Ok, it seems you're correct about Cannon Lake: https://software.intel.com/sites/default/files/managed/c5/15/architecture-instruction-set-extensions-programming

Ok, it seems you're correct about Cannon Lake: https://software.intel.com/sites/default/files/managed/c5/15/architecture-instruction-set-extensions-programming-reference.pdf https://software.intel.com/sites/default/files/managed/c5/15... Cannon Lake and later according to Intel. However, I question "mainstream" since many Celeron and Pentium branded parts featured SHA-NI, and those are arguably mainstream, low-cost parts. Also, in fairness to Phoronix, it looks like SHA-NI support may have been planned for Skylake, but didn't make it based on various posts I see online as early as 2014 and Intel's first postings about SHA-NI on Goldmont, etc. in 2013.

It was possible for Larabel to verify the facts before publishing and he just didn't. Nor did he correct the mistake in any of the past three years.

  Sure, quite a few processors were based on Goldmont: https://en.m.wikipedia.org/wiki/Goldmont https://en.m.wikipedia.org/wiki/Goldmont
