What you need to know

  • Leaked slides detail Intel's upcoming Alder Lake-S CPUs.
  • The CPUs offer 20% better single-thread performance and double multi-thread performance over their predecessors.
  • The Alder Lake-S processors should launch in the second half of this year.

Details about Intel's upcoming Alder Lake-S processors have leaked online. A report by VideoCardz shares slides detailing Intel's 12th Gen CPUs.

According to the report, Intel claims 20% single-thread performance improvement on its Golden Cove core design. The Alder Lake processors will also allegedly be twice as fast in multi-threaded workloads. The slide mentions Intel's new Gracemont cores alongside the improved multi-thread improvements. VideoCardz points out that it's not known if these improvements are in comparison to Intel's Rocket Lake or Tiger Lake processors.

The Alder Lake CPUs feature Intel Hybrid Technology with small high-efficiency cores and big high-performance cores.

The Alder Lake CPUs will support PCIe Gen 5 and Gen 4 as well as DDR5 and DDR4. On the mobile CPU side of things, the Alder Lake processors support LPDDR4 and LPDDR5. A separate report from VideoCardz reveals that the Alder Lake chips will support LPDDR5X.

VideoCardz also shared details about the Intel 600 series chipset. The desktop CPUs will support dual-channel DDR5-4800 memory. Motherboards that are DDR-4 capable will support up to 3200 MHz modules, while high-end Z690 motherboards will offer DDR5 support, according to the report.

The CPU will support PCI Gen 5 and have 16 PCI Gen5 capable lanes. It will also have 4 PCI Gen4 lanes.

When Intel announced delays to its 7nm chips, the company also stated that its 10nm Alder Lake desktop CPUs were on the way. The new Alder Lake chips should arrive in the second half of this year, though we don't have an exact date. VideoCardz lists the launch date of the Alder Lake-S CPUs as Q4 2021.

  • I wonder how the 2x multi-threaded performance is achieved -- more cores or better bus handling to more effectively use multiple cores in parallel, or maybe a combination of the two... The PCIe Gen 5 bus is twice as fast as Gen 4. Does anyone know, or will we need to wait for Intel to formally announce these?
  • Supposedly Intel is following AMD's lead in ditching the internal bus and going with a crosspoint switching matrix internally. This alone will increase the multi-threading by avoiding bus-stalling.
    It also allows them to decouple the PCIe interface a bit, and make the changes necessary to allow DDR5 memory (hopefully.)
    Intel is in a bit of a bind with the 12th Gen Alder Lake-S however. If it DOES come out supporting DDR5 (and it SHOULD with the newer 600-series chipset) then it will cannibalize their recently launched 11th Gen products pretty badly.
    That is a marketing problem that will be interesting to see how they solve it. They REALLY need it to come out supporting everything however as AMD is not sitting on it's hands counting their cash. They are moving ahead to Zen4 and improving their power-ratio pretty quickly.
  • Thanks. I would think that AMD has a fundamental power advantage (even though they haven't yet passed Intel) being on 7nm. I've said it on other Windows Central pages too, but I really want a book to come out explaining Intel's trouble getting their fab process size down. There must be some dramatic stories behind their problems with that. It would be a must-read for me.
  • Intel 10nm has equivalent transistor density to TSMC 7nm. Intel delayed because they took many ambitious risks and many of them failed, , never expecting AMD to catch up , while AMD was able to squeeze out processors only somewhat better than Intel 14nm with a full node advantage. The meaningful comparisons will be between Ryzen 5000 and Alder Lake.
  • *TSMC was able to squeeze out *transistors only somewhat better
  • SMH. We've been hearing about 10nm for ages... I won't hold my breath. Also, how are they going to support PCIe Gen 5 when PCIe gen 4 just came out last year, and intel hasn't supported it until 11th gen?
  • There's a misconception here - the PCI-E 5.0 standard was released in 2019 (4.0 was released in 2016). It normally takes years for CPU and chipset manufacturers to catch up. Intel is just trying to get ahead of the curve with this, especially since the 6.0 standard is likely to be released later this year. Intel just adopted 4.0 on their chipsets last year. As of today, none of their desktop CPUs support 4.0 (Rocket Lake hasn't been released as of today).
