A stock 14900K scores 38476 (as per TPU review). 4 ecores account for roughly 3900 points (*4 that would be 15600).
38476 - 15,600 = 22876 (removal of ecore score).
22876 - 5200 (your number for disabling hyper threading, I assumed larger deficit previously) = 17676 (base pcore)
(17676 *1.10) + (15600 * 1.5) = 41,076
Without knowing final clock frequencies (which are as of intels mobile release guaranteed to be lower) and what gains from potential mitigations due to hyper threading removal, intel will barely surpass 14th gen in MT. I hope they focus more on improving efficiency and stock TDP, as both 13th and 14th gen are horrendous. I wouldn’t be bothered by a marginal shift in MT, but compared to the 9000 series, potentially not releasing until December is likely to make this new line of processors look poor vs the competition.
