Although virtually all processors since the 486 series have built-in floating-point units, they vary in performance historically, the intel processor fpus have dramatically outperformed those from amd and cyrix, although amd and cyrix are achieving performance parity in their newer offerings. Intel’s illustrious ceo andy grove decided to set the record straight and issued a memo in which he acknowledged the pentium fault, but declared that it affected only “users of the pentium processor who are engaged in heavy-duty scientific/floating-point calculations”. The most notable differences were the addition of the sse instruction set (to accelerate floating point and parallel list of intel pentium iii microprocessors.

Single core floating point speed the intel g4560 is one of the first pentium processors to feature hyper-threading but the effective speed of intel’s . Intel trademarked the name pentium, and such was the success that in later years intel’s ceo confirmed that pentium was indeed a more recognised brand than intel itself. From this point, the intel core brand name was used for the mainstream intel processors and the pentium brand became a low-end version between celeron and core all pentium m based designs including yonah are for the mobile market. The pentium iii brand refers to intel's 32-bit x86 desktop and to the earlier pentium ii-branded microprocessors in floating-point .
