    Phoronix: AMD + Older Intel CPUs To See Much Faster AES-NI XTS Crypto Performance On Linux 5.12

    AMD processors along with older Intel processors will enjoy much faster AES-NI XTS crypto performance with the Linux 5.12 kernel this spring...

    AMD is very slow.

        Yep, is fast:

        Cryptsetup Benchmark - OpenBenchmarking.org

        AMD Ryzen 9 5950X 16-Core === Intel Core i3-10100

        AMD EPYC 7702 64-Core < Intel Core i3-8100

          2 x Intel Xeon Platinum 8280 < Intel Core i3-10100

          Damn those expensive, top of the line Xeons are very slow indeed

          Benchmarking fixed function hardware (and that's what AES-NI is) is quite complex, but it looks like AMD's implementation is indeed slower in general.

            Does this 65% speedup mean that a Core i5 would now be fast enough for a home NAS or does one still need to buy i7/i9? For instance, 4x PCIe 4.0 SSD requires quite a bit of CPU power. Even the cheap motherboards often have 2.5 or 5 gigabit full duplex bandwidth per link.

              There are no desktop CPUs from Intel with PCIe 4.0 yet, that's coming with Rocket Lake. And even then you'd probably need a new motherboard due to increased CPU-chipset bandwidth for the upcoming Z590 chipset if you really want to use 4 SSDs. It might be possible to use the CPU x16 slot for that, but it requires support for PCIe bifurcation, and that's not common (for example ASUS has a list).

                Still way faster than AMD EPYC 7702 64-Core .

                  Why would you need PCIe SSD's for a home NAS? A newer mechanical HDD will saturate 2.5 Gbe, and 2x SATA SSD's will saturate 10 Gbe.

                    These are really desperate times for Intel fan boys. The only thing they have left is this fixed function hardware.

                    Personally, I prefer non-hardware crypto. Anything, which can be audited by third parties.
