FreeBSD identifies it as Samuel2, though. And I bought my Ezra as a Nehemiah. Via (VIA) has no clear distinction between the cores, even though there are some pretty big differences (full speed FPU, SSE support). It would have made sense to call it C3 then C4 then C5, or some other way to distinguish between the different chips. Resellers seem to have problems figuring out which chip it is that they're selling. All I know is that the product line went: Samuel -> Samuel2 -> Ezra -> Ezra-T -> Nehemiah However, one page seems to indicate that the product line went more like: Samuel (C5A) -> Samuel2 (C5B) -> Ezra/Samuel3 (C5C) -> Ezra-T (C5N) -> Eden -> Nehemiah where Eden is really just a bundled chip (with a specific VIA north/south bridge). So maybe they do have a way to distinguish the chips. Dunno -- at the very least, it's not marketed. And the Samuel2 is definitely not an Ezra. FWIW, the best way I've seen to figure out which chip you're using (at least between Ezra/Ezra-T and Nehemiah) is to look at the clocking -- Ezra/Ezra-T seems to be 100*10.0, whereas Nehemiah seems to be 133*7.5.
