So is P550 ... 8.65 is the claim I think. It doesn't have the MHz though. My i7-4790K (which is still in the back room somewhere) had a base of 4.0 GHz and could turbo to 4.2 or 4.4. My Megrez is doing just 1.8 GHz.
RVA23 requires V. These incoming CPUs are the real deal, a perfectly usable performance level in the present day.
(unless they cache-starve them or some other such fuck up)
My 4790k was still my main PC until I recently (weeks) built a new PC with 9800x3d, 96GB ECC, rx7900gre.
4790k had 4 cores. If these new chips clock reasonably, say, 3+ GHz, and have 8 or 16 cores, they'll easily generally outdo this old -but very usable still- Intel chip.
