Why this matters: Intel's leaked 28-core desktop lineup — topped by a new "BFC" chip with a big last-level cache — finally shows how it plans to take on AMD's gaming-CPU dominance, and the confusing new names are already worrying shoppers.
October 4, 2026 — A leak posted October 1 by LC Tech Leaks claims to name seven Nova Lake-S desktop processor identifiers spanning Core Ultra 9, Ultra 7, and Ultra 5 — adding a new top-tier Core Ultra 9 4970K "BFC" above the previously leaked Core Ultra 9 4950K.

Editor's Highlight: The key detail is the "BFC" suffix: three of the seven leaked chips carry it, and every BFC part is paired with bLLC — suggesting Intel will make big last-level cache a mainstream product line, copying AMD's most successful desktop play of the last five years.

Key Facts
| Detail | Information |
|---|---|
| Leak source | LC Tech Leaks, posted Oct 1, 2026 |
| Chips leaked | Seven Nova Lake-S SKUs, Core Ultra 9/7/5 |
| Top chip (leaked) | Core Ultra 9 4970K BFC — 28 cores, 125W |
| New suffix | "BFC" on three SKUs, aligned with bLLC parts |
| Cache (reported) | bLLC up to 144 MB L3, per Tom's Hardware |
| Platform | New LGA 1954 socket, 900-series chipsets |
| Launch window | Early 2027, per reports; Intel confirmed nothing |
| Missing from leak | The rumored 52-core dual-compute-tile part |
The leaked seven-SKU lineup
The leaked table, reported first by VideoCardz and independently by Overclock3D, puts Intel's Nova Lake-S desktop family across the Core Ultra 9, Ultra 7, and Ultra 5 brands. The leak supports earlier reports that Nova Lake moves desktop Core Ultra chips to four-digit model numbers — the "Core Ultra 4000" series.
Three of the seven identifiers carry detail. The remaining four are not yet publicly detailed — the figures below are leaked claims, not Intel-confirmed specifications.
| Leaked model | Cores (leaked) | TDP (leaked) |
|---|---|---|
| Core Ultra 9 4970K BFC | 28 (8P+16E+4LP-E) | 125W |
| Core Ultra 9 4900 BFC | 22 | 65W |
| Core Ultra 7 4870K BFC | 24 | 125W |
Notably absent is the long-rumored 52-core dual-compute-tile part — Hardware Busters reports it is expected to follow the main lineup later.
Tech Analysis: Three BFC parts leading the leak is unusual — Intel appears to be leading with cache-equipped chips instead of saving them for a later refresh.
The 4970K flagship: what the leak claims
Per the leaked table, the Core Ultra 9 4970K BFC pairs 8 P-cores, 16 E-cores, and 4 LP-E cores (28 total) with a 125W TDP, a 32-EU iGPU, and vPro. It is identified as a bLLC part.
Tom's Hardware, via Hardware Busters, puts the bLLC L3 pool at up to 144 MB — which would make the 4970K BFC the most cache-heavy Intel desktop chip ever, aimed squarely at AMD's X3D lineup.
Newsroom Focus: Every one of these numbers is a leaked claim. Intel has not confirmed the 4970K exists, let alone its cores, cache, or TDP. Treat this as a roadmap rumor with unusually specific details, not a product announcement.
"BFC" and the cache war with AMD
The exact meaning of "BFC" is unconfirmed, but the pattern is clear: all three BFC parts in the leak are bLLC-equipped. The leading theory is that BFC marks the big-cache variants — Intel's equivalent of AMD's "X3D" branding.
AMD's 3D V-Cache stacks extra cache silicon onto the CPU die — a design that made Ryzen X3D the default gaming-CPU recommendation. Intel's bLLC reportedly puts 144 MB of last-level cache on the die itself instead of stacking it — a different engineering route to the same goal: keeping more data close to the cores so games run faster.
Practical Takeaway: This leak changes nothing for holiday-season buyers — Nova Lake is not expected until early 2027. But it signals that by next year both CPU makers may compete primarily on cache, which has historically been good news for buyers.
New socket: LGA 1954
According to the reports, Nova Lake-S will use a new LGA 1954 socket with 900-series chipsets, replacing LGA 1851. Qualification samples are already showing up in HWiNFO, suggesting engineering samples are circulating.
The consequence for upgraders: a Nova Lake move will almost certainly require a new motherboard. Reports point to an early 2027 launch — again, unconfirmed by Intel.
The naming mess: HX laptops join Core Ultra 4000
Separately, leaker Jaykihn claims Nova Lake-HX laptop chips will use the same four-digit Core Ultra 4000 names as desktops, while H-series mobile parts stay on three-digit names — leaving laptops with two schemes at once.
A desktop "Core Ultra 9 4950K" and a four-digit HX laptop part would look like siblings, while H-series laptops used different numbering entirely. After three renames in three years, shoppers face genuine confusion — exactly the concern Hardware Busters flagged.
Bottom Line
If accurate, Intel's next desktop generation bets on more cores (28 in the 4970K BFC) and far more cache (up to 144 MB) as a standard product line — the most direct challenge to AMD's gaming dominance in years.
None of it is confirmed. Watch for the rumored 52-core part surfacing in later leaks, and for Intel to confirm the BFC branding and LGA 1954 platform ahead of the reported early-2027 window.
FAQ
Is the Core Ultra 9 4970K BFC confirmed by Intel?
No. It comes from an Oct 1, 2026 leak by LC Tech Leaks, reported by VideoCardz and Overclock3D. Intel has confirmed none of it — not the chip, the specs, the BFC suffix, or the launch timing.
What does "BFC" mean?
Unconfirmed. All three BFC parts in the leak are bLLC-equipped, so the leading theory is that BFC marks the big-cache variants — Intel's counterpart to AMD's X3D.
How much cache does the bLLC variant have?
Tom's Hardware, via Hardware Busters, reports up to 144 MB of L3 — which would be Intel's largest desktop CPU cache ever, aimed at AMD's 3D V-Cache gaming lead.
Will Nova Lake need a new motherboard?
Per the reports, yes: Nova Lake-S is expected on the new LGA 1954 socket with 900-series chipsets, replacing LGA 1851.
When does Nova Lake launch?
Reports point to early 2027 for Nova Lake-S, with the rumored 52-core part following later. Intel has confirmed none of this.
