That is more than double the 128 MB slapped into AMD’s Ryzen 9 9950X3D and comes from the usually accurate leaker kopite7kimi, who dropped the hint after poking at chatter about 144 MB allocations for Chipzilla’s so-called big last-level cache.

Kopite7kimi then claimed some Nova Lake models will have two compute tiles, which means double the stacked cache, giving Chipzilla a hulking 48 cores and 288 MB of bLLC, plus another four low-power cores in the SoC tile for a tidy total of 52. A shipping manifest has already hinted at that core count.

There is talk of another model with eight performance cores and 12 efficient cores that still gets the fancy cache, although the exact amounts remain murky. Chipzilla will trot out single-tile versions across both core and cache layouts, leaving four Nova Lake CPUs offering the bLLC option.

Kopite7kimi said: “The power supply design of the new platform will be a challenge for motherboard manufacturers”, and it is hard to disagree when Chipzilla is shoving that much silicon into one package.

PC Gamer points out that the cunning plan looks like an all-out assault on AMD’s gaming lead and a grab for bragging rights when Nova Lake appears at the end of 2026. AMD, of course, will not sit around polishing trophies and has already said Zen 6 will land in the same year.

Next year is lining up as a stacked-cache dust-up between the two chipmakers, assuming the memory supply gremlins have finally gone on holiday.
