While Rocket Lake-S has just been announced, we now have new rumors about Intel's 12th gen Core Alder Lake-S CPUs, which could bring as high as 20 percent higher single-thread IPC improvement, support for both PCIe 4.0 and PCIe 5.0, as well as DDR5 memory support.

According to a leaked set of slides coming from, Alder Lake could feature up to 20 percent single-thread performance improvement, thanks to the enhanced 10nm SuperFin manufacturing process and the new Golden Cove CPU architecture. The slide also mentions a 2x multi-thread performance improvement thanks to Gracemont cores and hardware-guided scheduling, as well as improved general SoC power, with design optimizations and energy-aware Core Parking.

In addition to performance improvements, the new Alder Lake will also feature the latest I/O, with PCIe Gen5 and PCIe Gen 4 support, full memory support with DDR5 and DDR4, as well as LPDDR5 and LPDDR4, and Intel WiFi 6E and Thunderbolt 4 connectivity.

The platform comes with a new LGA1700 socket, which means a whole new 600 series chipset. The entry-level 600-series chipset will stick to DDR4 support while high-end boards will come with DDR5 support.

Intel's Alder Lake platform is rumored to launch later this year, but it is still not clear if Intel plans both mobile and desktop rollout.

Intel's new CEO, Pat Gelsinger, has scheduled a webcast on March 23rd, and hopefully, we will hear more about Alder Lake as well.
