Rumor mill: A leaked list of seven Nova Lake-S desktop processors gives us the clearest look yet at how Intel plans to sell its first consumer chips with a massive last-level cache. The upcoming flagship appears to be the Core Ultra 9 4970K BFC, positioned above the Core Ultra 9 4950K. The list suggests "BFC" will mark the large-cache models across three tiers.
At first glance, the four LP-E cores look exclusive to the BFC models, however Intel leaker Jaykihn says the standard chips have them too, along with vPro support, but the table simply omits them. A previous 4950K CPU-Z leak supports this: it showed 28 cores, not 24. Without the LP-E cores, the 4950K's 8P+16E layout would match today's Core Ultra 9 285K, which would make for a clean generational comparison.
The newly leaked table comes from LC Tech Leaks, the same source behind the 4950K CPU-Z screenshot a few weeks ago. The naming is still unofficial, but it supports the idea that Nova Lake will move Core Ultra desktop chips to four-digit model numbers as shown below:
Intel's internal documents have called the technology bLLC, for "big last-level cache." BFC could be the final retail branding that would compete against AMD's well-established 3D V-Cache technology. Nobody knows what "BFC" stands for, but enthusiasts have already filled in the blank with their own guesses.
The configurations in the table line up with earlier reports, a recent leak pointed us to 22-core Nova Lake-S parts with up to 144MB of cache , and the 6P+12E+4LP-E Core Ultra 9 4900 BFC matches that layout.
