Intel’s first foray into hybrid processors using Foveros 3D stacking technology did not end well with the company just announcing the end of the life for Lakefield hybrid processors. But the company is not giving up on hybrid technology, and a recent leak shows the Intel Alder Lake family comprised of more powerful mobile hybrid processors will be offered for a wide range of applications from tablets with 5-7W M5 processors and up to “muscle laptops” or mobile workstations (MWS) with H55 processor at 45-55W TDP.
Alder Lake hybrid processors will be comprised of high-performance CPU “Golden Cove” cores and energy-efficient Atom-based “Gracemont” CPU cores, in a way that’s similar to Arm’s Cortex-A7x big cores and Cortex-A5x LITTLE cores with big.LITTLE or DynamIQ processing with the goal of optimizing power consumption.
The Intel Alder Lake Mobile SKU stack includes processors for 6 market segments including three “new” segments/TDP ranges according to the slide:
- Alder Lake-M family
- Intel M5 (New) – 5W-7W Core i3/i7 processors for tablets with one big core, four small cores, and 48 or 64 EU graphics
- Intel U9 – 9W- 15W Core i3/i5/i7 processors for ultra-thin laptops with two big cores, four or eight small cores, and 80 or 96 EU graphics. Not quite sure what the dotted lines mean, but the table also shows an additional 1 big + 4 small + 48EU graphics Celeron/Pentium processor
- Alder Lake-P family
- Intel U15 – 12W/15W/20W Core i3/i5/i7 processors for mainstream laptops and tablets with the same configuration as U9, but likely higher clock speeds
- Intel U28 (New) – 20W-28W Core-i5/i7/i9 SoCs for “performance” laptops and tablets in either 4 big + 8 small or 6 big + 8 small configuration with all equipped with 96EU graphics
- Intel H45 – 35W–45W Core i5/i7/i9 chips for “thin enthusiast” laptops using either 4 big + 8 small or 6 big + 8 small cluster configurations, and again 96EU graphics
- Alder Lake-S family (socketed BGA1964 package)
- Intel H55 (New) – 45W-55W Core i7/i9 processors for “muscle” laptops and MWS with eight big cores, eight small cores, but only 32EU graphics, possibly because a discrete card might also be used. A dotted box also shows a Core-i5 model with four big and 8 small cores.
Intel Alder Lake hybrid mobile processors are expected to become available later this year.
