Regex Editor & Tester

This regex matches CPU component generation model names, specifically core processor brands like XEON, xeon, ITANIUM, OPTERON, PENTIUM, and UltraSPARC (case-insensitive for most). It optionally captures a Roman numeral generation suffix (III, II, ii, iii) separated by a space. Useful for extracting or classifying processor types from text logs, product listings, or system inventories.
