Leaked Nova Lake-S table lists seven desktop identifiers, with Core Ultra 9 4970K BFC at 8 P-cores, 16 E-cores, and 4 LP-E cores. It also shows a 125W rating, a 32-EU iGPU, and a bLLC mark. The 4950K sits below it with the same P/E split but no bLLC mark in the table. The 4970K BFC therefore has 28 total cores, while the 4950K row totals 24.

Lower rows include 4900 BFC at 65W, 4870K BFC at 125W, 4850K, and two 4650K parts. The 4650KF has no iGPU entry, while the 4650K has 32 EU. All seven rows carry vPro marks. The platform note points to LGA 1954 and 900-series desktop chipsets for the platform.

Die Brief reads the table as a cache-tier split, not a clock or performance claim. The BFC rows add LP-E cores and bLLC, which constrains board and power design more than the nominal 125W label suggests. A buyer should treat the 4970K BFC as a different part, not a faster 4950K.

The document does not measure clocks, boost behavior, price, launch date, or the meaning of BFC. It also leaves out memory configuration, TDP max, and whether the 4950K sample still has LP-E cores. Earlier leak references to 144MB bLLC are not tied to a specific SKU here. No retail name is confirmed at this point.

The document leaves out clocks, boost behavior, price, launch date, memory configuration, and the meaning of BFC.

The table separates BFC rows by LP-E cores and bLLC, so the 4970K BFC is a different silicon configuration, not a higher-clock 4950K. Buyers and board designers should expect different cache, power, and platform assumptions.
