- tpearson-raptor 8y agoAll POWER products offer SMT. The POWER9 OpenPOWER chips are all 4 threads per core (SMT4), so a 4 core device presents 16 logical cores to the OS. POWER's hardware threading system is also unique and has high performance compared to offerings from other vendors (mainly x86) -- check out the processor user manual [1] for all the details.

- dragontamer 8y ago> The POWER9 OpenPOWER chips are all 4 threads per core (SMT4) Some are SMT8. The ones that are supported by this motherboard are "only" SMT4 however. I think its "OpenPOWER" chips are at least 4-threads per core.
- classichasclass 8y agoCumulus are the SMT-8s. I think you're thinking of the PowerNV vs PowerVM distinction.
