Intel's Comet Lake-S CPUs will require new LGA 1200 sockets, launching early 2020

New leaked slides show that the Comet Lake-S desktop CPUs are scheduled to replace the current gen 9 Coffee Lake-R models in early 2020. Intel will release a new 400-series chipset to support the upcoming CPUs that come with up to 10 cores / 20 threads and TDPs of up to 125 W. Unfortunately these will not be compatible with current motherboards, as the slides reveal the necessity of a new LGA 1200 socket.

Earlier this week, a leak revealed spec and pricing information for the entire desktop range of Intel Comet Lake CPUs, and it looks like these are not going to feature any 10 nm tech, at least for the mainstream models. Instead, Intel will add a 14 nm++ node and will bump the max TDP to max 125 W. Newer leaked slides also inform that there will be a new Intel 400-series chipset arriving in early 2020 and the new motherboards will include an LGA 1200 socket, making the Comet Lake CPUs incompatible with currently available motherboards.

The 125 W TDP is reserved for enthusiast models with 10 cores and 20 threads, while the corporate / mainstream models will only need 65 W and the low power versions just 35 W. Intel was against the introduction of PCIe 4.0, and its absence from the new platform comes as no surprise. It supports up to 24 chipset PCIe 3.0, up to 6 USB 3.1 Gen 2, up to 6 SATA 3.0 ports, plus PCIe 3.0 storage solutions like Intel Optane memory or NVMe M.2 SSDs. The chipset can handle 30 lanes, while the CPU will still provide the usual 16 lanes. Native RAM compatibility is still limited to dual-channel DDR4-2666.

Other key platform features include:
•    Enhanced core and memory overclocking via Turbo Boost 2.0
•    Rec.2020 and HDR support, HEVC 10-bit hardware acceleration, VP9 10-bit acceleration, UHD / 4K support
•    Integrated Intel Wireless-AX support
•    Thunderbolt 3
•    Smart Sound Technology with quad-core audio DSP
•    Modern Standby option

I first stepped into the wondrous IT&C world when I was around seven years old. I was instantly fascinated by computerized graphics, whether they were from games or 3D applications like 3D Max. I'm also an avid reader of science fiction, an astrophysics aficionado, and a crypto geek. I started writing PC-related articles for Softpedia and a few blogs back in 2006. I joined the Notebookcheck team in the summer of 2017 and am currently a senior tech writer mostly covering processor, GPU, and laptop news.
