Wide SMT/CMT is also favored by Oracle's billing system - you aren't billed (afaik) per-thread but actually per-core, so 4-wide SMT or 8-wide SMT gives you an advantage over x86's 2-wide SMT. In theory the "core multipliers" are supposed to offset this, so a "core multiplier" for POWER or SPARC should be higher - but Oracle also likes to push you towards their own products, so there is a bit of a "bundle discount" particularly on SPARC's core multiplier. |
