Intel Alder Lake-S to bring a 20% boost to single-thread performance

New Intel Alder Lake-S details have leaked this week, giving us a glimpse at what to expect from Intel's hybrid architecture CPU design. As it turns out, Alder Lake-S could provide a significant performance boost, with leaked presentation slides detailing a 20 percent uplift in single-thread performance. 

As per the slide leaked by Videocardz, these processors will have up to 8 Gracemont and 8 Golden Cove CPU cores, confirming early rumours about the hybrid CPU architecture. Besides the single-thread uplift, Alder Lake-S will also offer up to 2x more multi-thread performance by using the new Gracemont cores and “hardware-guided scheduling”.

Other interesting features coming with Alder Lake-S include support for PCIe 4.0 and 5.0, DDR4/5 memory, and LPDDR4/5 memory. Moreover, Alder Lake-S will bring design optimisations to the power delivery system, including energy-aware core parking.

There's also a slide that goes over the Intel 600 series chipset, confirming both DDR4 and DDR5 dual-channel memory will be supported. This support will likely be split up between high-end and entry-level motherboards, with top-end motherboards supporting DDR5-4800 and entry-level boards offering DDR4-3200 support.

The slide further details that the processors will have 16x PCIe 5.0 lanes and 4x PCIe 4.0 lanes, while the chipset supports PCIe 4.0 and 3.0 devices. Additionally, the 600-series chipset will feature the new LGA1700 socket and support Intel Optane Memory H20, Intel LAN PHY, Wi-Fi 6E, and Thunderbolt 4.0 (USB4 compliant).

Intel is scheduled to launch the first Alder Lake processors later this year, although it is unclear if this is a launch for desktop or mobile platforms at this time.

KitGuru says: Intel Alder Lake is a significant design shift for Intel, so it is going to be interesting to see performance at launch. A 20% improvement in single-thread performance sounds promising. Although splitting up DDR4 and DDR5 support between higher-end and lower-end motherboards could cause some confusion. Do you think Intel will separate DDR5 and DDR4 support on 600-series motherboards?
