A possible Intel Nova Lake-S range is filtered with a Core Ultra 9 4970K BFC
A leak attributes the future Intel Core Ultra 4000 family to Nova Lake-S seven references of desktop processors. The list places a supposed Core Ultra 9 4970K BFC above the 4950K known from previous information. It includes core, power, and integrated graphics configurations, although Intel has not confirmed brand names or specifications.
The main novelty would be the appearance of variants with an expanded last level cache. VideoCardz links the entries marked bLLC to previous leaks about Nova Lake-S, but the amount of cache allocated to each reference is not included in the new list. Therefore, the model number and the BFC brand do not yet allow us to anticipate its performance.
The alleged Core Ultra 9 4970K BFC
The highest entry combines eight P cores, 16 E cores and four LP-E cores. The sum gives 28 cores. The leaked table adds 125W power, integrated graphics described as 32 EU, and vPro support. It also notes the presence of bLLC, an abbreviation used for a configuration with more last level cache.
The Core Ultra 9 4950K appears immediately below. The text accompanying the leak describes it with eight P and 16 E cores, without the expanded cache. That would give 24 cores. There is, however, a contradiction within the post itself: One version of their table places four LP-E cores in the 4950K row, but keeps the total at 24. Those two figures can’t be correct at the same time. Before reproducing a closed configuration for the 4950K, it will be necessary to know the original document or an unequivocal correction.
The difference should also not be confused with a speed measurement. Neither the 4970K nor the 4950K have published final frequencies, and the 125W in the table is a power rating, not a consumption test during gaming or applications. The nomenclature suggests that the 4970K would occupy a higher position if both names reach stores unchanged.
BFC variants drop to Core Ultra 7 and 65W
The relationship includes a Core Ultra 7 4870K BFC with eight P, 12 E and four LP-E cores. There would be 24 cores and an indicated power of 125 W. Next to it appears the Core Ultra 7 4850K, with eight P and 12 E, without bLLC in the table and with a total of 20 cores. The combination reproduces the pattern of a standard reference and another with the extended cache configuration.
Another entry marked BFC is the Core Ultra 9 4900. It appears with six P, 12 E and four LP-E cores, which adds up to 22, and is classified at 65 W. This reference indicates that the supposed bLLC variants would not be limited to 125 W K models. Their final position in the catalog, however, will depend on how Intel organizes the families and prices.
The two Core Ultra 5s on the list are 4650K and 4650KF. Both are described with six P and 12 E cores, for 18 in total, and with 125 W. The 4650K would have 32 EU integrated graphics; the KF entry lacks them. That distinction coincides with the common use of the letter F in Intel processors, but remains part of an unofficial relationship.
Table attributes 32 EU graphics to models with integrated GPU. That number describes execution units, but is not enough to estimate their performance: frequencies, confirmed architecture and power limits are missing. Furthermore, the presence of a GPU integrated into the processor does not indicate what video connections the motherboards will have. These outputs will depend on the models manufactured by Intel’s different partners.
What does it contribute compared to previous rumors?
In April, there was talk of a preliminary list of Nova Lake-S with configurations from six to 52 cores and various power levels. That information pointed to versions with a single calculation block and others with two, in addition to DDR5 memories of up to 8,000 MT/s and a new generation NPU. The new leak takes a different step: proposes commercial numbers for seven specific references.
The 28 cores of the 4970K BFC fit one of the single block configurations described then. Variants with 24 and 22 cores with expanded cache also appeared, close to those now attributed to the 4870K BFC and the 4900 BFC. This fit between rumors is not equivalent to independent confirmation: both information may come from preliminary material subject to change.
Other leaks place Nova Lake-S on the LGA 1954 socket and on boards with 900 series chipsets. Neither the definitive compatibility of the boards nor the commercial meaning of the BFC suffix have been explained by Intel. There are also no prices, final frequencies or verified results that allow these references to be compared with current processors.
The list provides names and a possible organization of the range, but keeps open the data that will decide its real interest. Intel has yet to confirm which models will go on sale and correct the inconsistency affecting the published configuration of the 4950K.
