    I wish AMD and Intel would take notice, why are we still using SMT when SMT4 and SMT8 exist? Imagine if either AMD or Intel released a 4C/16T or 4C/32T processor, everyone would go nuts. SMT can be added to a cpu for relatively cheap from an added circuitry standpoint and tests with 12C/96T cpu vs a 24C/96T cpu show that under some workloads the former is faster than the latter.

    I noticed that as well. I think you're reading that correctly. Just not sure what would cause that result.
