CPU release dates in the table above were compiled from product press releases and official price lists. For some processors we used approximate launch dates within a month or a quarter, that were obtained from product roadmaps. In the case of OEM-only models, that are not referenced by the above-mentioned sources, we used month and year when product specifications appeared on manufacturer website.
