Leaked Intel Nova Lake product list has three ‘BFC’ chips with up to 144MB of game-boosting L3 cache

A rumored SKU table for Intel’s upcoming Nova Lake desktop CPUs has surfaced, showcasing seven models that will (presumably) make up Intel’s initial NVL-S lineup. The list includes three models with the “BFC” tag, which seems to be Intel’s branding for bLLC, or big last level cache. It’s been heavily rumored to show up with Nova Lake, countering AMD’s assault on the best CPUs for gaming with its X3D chips.

As previously rumored, the table tops out at the flagship Core Ultra 9 4970K BFC, which the spec list suggests is a 28-core chip with 8 P-cores, 16 E-cores, and 4 LPE-cores. It also lists a 125W TDP and an integrated GPU with 32 Execution Units (EUs). This 32-EU iGPU is apparently a staple across the range, short of the Core Ultra 5 4650KF, which lacks integrated graphics.

Intel retired the use of “EUs” in favor of its Xe cores several years ago. Rumors suggest Intel isn’t releasing a large, 12-Xe core model of Nova Lake. The 32-EU count here likely comes out to 4 Xe cores (each core has eight matrix and vector ALUs).

The table does not include the heavily rumored 52-core Nova Lake model. However, as the Nova Lake launch approaches, it has become clear that the 52-core model, as well as other potential models with a dual-tile configuration, will arrive after the main range of chips. Presumably, these models will target the HEDT crowd with their high core counts.

*Names and specifications rumored, unconfirmed by Intel

There are several interesting details when looking at the range broadly. Most notably is the four-number model identifier, which Intel didn’t use with Arrow Lake chips like the Core Ultra 7 270K Plus. This larger identifier has been previously rumored, and it makes sense if the lineup above is indeed real. There’s quite a bit of specificity in this stack, and something like the “Core Ultra 9 497K” doesn’t signal what a “Core Ultra 9 4970K” does.

Regardless of naming, the SKU table shows three models with BFC, two of which fall under the Core Ultra 9 umbrella. There isn’t a Core Ultra 5 BFC option. The most interesting model is the Core Ultra 9 4900 BFC, which matches the 22-core count of the Core Ultra 5 models, though with the addition of BFC and a lower 65W TDP. Given this chip doesn’t have a K suffix, it looks like a specialized, low-power gaming chip, perhaps for small form factor desktops.

In addition, the Core Ultra 5 model is the only one with an F suffix, noting that it lacks integrated graphics. As we saw with the Arrow Lake refresh, Intel released a Core Ultra 5 250KF Plus, though it never gave the 270K Plus the KF treatment.

According to the table, Intel could use “BFC” to note chips with a larger L3 cache, something that’s been heavily rumored for Nova Lake as AMD’s X3D chips dominate gaming in our CPU benchmark hierarchy. This is the first time we’ve heard it referred to as BFC; however, with previous rumors referring to the additional cache as bLLC.

As for what BFC stands for, there are a few possible candidates, and we’ll leave it to your imagination as to what words that start with “F” could fit between “Big” and “Cache.”

Although Intel’s Nova Lake chips have been the topic of the rumor mill for well over a year, the launch is approaching. At the beginning of the year, Intel’s CEO confirmed Nova Lake would arrive before the end of the year. Assuming that’s still true, we’d expect to learn more any day now.

Signs certainly point to a launch happening soon. Just this week, Nova Lake platforms passed compliance at USB and PCIe standard bodies. At Computex earlier this year, we saw two Z990 motherboards in the flesh. And last month, a leaked slide presumably from one of Intel’s partners provided a tease as to what the platform could look like.

Hopefully we’ll have more details soon. In the meantime, make sure to check out our recent interview with Intel’s Robert Hallock, where the executive goes into some of the expectations around Nova Lake, on Tom’s Hardware Premium.
