The Rocket Lake and Alder Lake CPUs will be launched this year, but only the latter will be the turning point for Intel, as they are made with a production process (6 years after the release of Broadwell) and an architecture design brand new
Rocket Lake will arrive on the market for the middle of March (somewhat late compared to the Z590 and B560 motherboards already regularly on the market), but Alder Lake should not be long, not surprisingly from many parts insistently that it could be launched even in September.
Alder Lake will be produced on the 10nm Enhanced SuperFin node which offers a 15% reduction in power consumption, while the Golden Cove architecture is expected to deliver IPC gains of at least 20% compared to Willow Cove.
For comparison, the Cypress Cove cores on Rocket Lake CPUs have about 18% better IPC than Skylake (Willow Cove is only slightly higher).
Overall, Golden Cove cores would deliver a 40-50% CPI increase over Skylake, confirming early rumors.
As for the “small” Gracemont (Atom) cores, it seems that the performance is similar or slightly better than the Skylake cores, but with a much lower power draw.
Alder Lake will therefore be Intel’s first mainstream desktop processor based on the new 10nm SuperFin manufacturing process, a “hybrid” chip that combines larger “Golden Cove” cores and smaller “Gracemont” cores, similar to the big architecture. LITTLE by ARM or big.SMALL, to offer significantly improved energy efficiency.
Compatible only with the new LGA1700 socket (which has dimensions equal to 45×37.5mm against the 37.5×37.5mm of the current LGA1200), Alder Lake-S should offer more extensive connectivity and a platform with support for new standards such as DDR5, PCIe 5.0 and, perhaps, also ATX12VO, the new 10pin power connector.
Alder Lake’s true competitor will be Zen 4, but those CPUs won’t see the light until 2022 due to TSMC’s underpowered 5nm node production capacity, which is why it’s possible AMD will release an intermediate solution like the Warhol range of CPUs. Ryzen based on Zen 3+ made with 6nm production process.
