Partial tests not showing all CUs and RT cores with a stress test at 2000Mhz, 18>36>54.
Yeah I've still been entertaining a future Oberon stepping that might have an extra block of CUs on it. Either 48 or 54 (the latter is a clean tripling of 18). And FWIW, Arden was in that Github leak and somewhat fits the naming scheme, it just has not had any further benchmarks uncovered that we know of.
So I guess all we need is a future GPU benchmark leak/datamine reflecting/confirming all this and we'd be peachy good. Would probably still be named Oberon but could be Arden I guess (assuming Arden is related to PS5; IIRC Arden isn't a Shakespear character but there've been a series of modern-ish books published in the Arden Shakespear line dating back to 1995).

's question about the 2GHz clocks and clocks for regression testing is still valid but it's possible they were just trying to push that version of Oberon to get near a performance target while waiting for more mature silicon. So it's possible the Oberon steppings so far are max 40CU chips but there's been a later stepping or revision with more CUs on it coming down the production line after those. Not sure if it would still be called Oberon or something else however (I mean, wouldn't a chip with revisions that big be classified under a different name?).
