PC Builders: NVIDIA RTX Spark lands October 7, and a Nova Lake table leaks
Two items for anyone planning a build: an Arm laptop and mini-PC platform with a firm date, and a desktop CPU lineup that is still a rumor.
Hardware news comes in two kinds. Some has a date and a spec sheet. Some has a leak and a guess. This first PC Builders edition has one of each, and I label which is which.
The short version
Reported by TechPowerUp on October 1, 2026: NVIDIA’s RTX Spark platform of mini PCs and laptops is set for October 7, according to a teaser from Microsoft’s Windows account that NVIDIA’s RTX Spark account corroborated. Reported by Tom’s Hardware on October 2 as a rumor: a table of seven Intel Nova Lake desktop chips, three of them tagged BFC for big cache. Intel has not confirmed names or specs. I did not test any hardware.
NVIDIA RTX Spark: a date, no price
Fact, as reported (TechPowerUp, October 1): October 7 is the launch date for RTX Spark mini PCs and laptops, shown in a teaser on X from Microsoft’s Windows account and corroborated by the RTX Spark account. Acer, ASUS, Dell, MSI, HP, Microsoft, Lenovo and others are named as launch partners, and ASUS has teased a ProArt 16 creator laptop on it. The N1X chip comes in two versions. The top one has a 20-core Grace CPU, a Blackwell GPU with 6,144 CUDA cores and 24 to 128 GB of unified LPDDR5X, for laptops and mini PCs. The second has 18 cores, 5,120 CUDA cores and 24 to 32 GB, aimed at laptops that run Windows 11 for Arm as Copilot+ PCs.
Not stated: prices, ship dates by model, battery life and any benchmark. The article’s own reader comments ask about price. Nothing I read answers it.
My analysis: the unified memory range is the number a builder should look at. It is soldered, so you pick your memory when you buy, not later. Wait for October 7 and independent reviews before treating any figure as a result.
Intel Nova Lake desktop: a rumored table
Rumor (Tom’s Hardware, October 2): a leaked SKU table lists seven models. Three carry a BFC tag, which the outlet reads as Intel’s name for a big last-level cache, countering AMD’s X3D chips. The headline puts up to 144 MB of L3 on those parts.
| SKU (rumored) | P + E + LPE cores | TDP | iGPU EUs |
|---|---|---|---|
| Core Ultra 9 4970K BFC | 8 + 16 + 4 | 125 W | 32 |
| Core Ultra 9 4950K | 8 + 16 + 4 | 125 W | 32 |
| Core Ultra 9 4900 BFC | 6 + 12 + 4 | 65 W | 32 |
| Core Ultra 7 4870K BFC | 8 + 12 + 4 | 125 W | 32 |
| Core Ultra 7 4850K | 8 + 12 + 4 | 125 W | 32 |
| Core Ultra 5 4650KF | 6 + 12 + 4 | 125 W | - |
| Core Ultra 5 4650K | 6 + 12 + 4 | 125 W | 32 |
Inconsistency to know about: the article’s text and headline call the flagship a 28-core chip, but its table lists 24 for the same row, and 8 + 16 + 4 adds up to 28. I do not know which is right, so the table above shows the core split and leaves the total out. The report also says a 52-core model is not in this list and is expected after the main range.
My analysis: a four-digit naming scheme, a 65 W BFC part with no K suffix and an F-suffixed Core Ultra 5 without graphics all look specific enough to be real. They are still unconfirmed. Do not buy a motherboard for a socket and chip you have only seen in a leak.
What to do with this
- If you are buying an Arm laptop or mini PC, wait for the October 7 specs and prices.
- If you are building a desktop this quarter, plan on parts that are on sale now. Treat Nova Lake as a possible later upgrade, not a reason to wait.

I read both articles on October 5, 2026. The facts are the outlets’ reporting. The labels and analysis are mine. I tested no hardware and ran nothing.
