Intel's next-generation 400-series chipset motherboards from Gigabyte have been leaked & listed through their EEC certification (Videocardz via TUM_APISAK). The Intel 400-series chipset will offer support for 10th Generation Comet Lake-S processors which is scheduled to arrive early next year.

Intel 400-Series Chipset Based Motherboards Including Z490 Series From Gigabyte Leak Out - Designed For 10th Gen Comet Lake-S CPUs

There are a total of 35 motherboards that have been listed which are based on 400-series chipsets. The chipsets themselves include Z490 (flagship mainstream), H470, B460 & H410. Gigabyte/AORUS may have even more motherboards at launch but these are the ones we know so far. The boards that have been listed include:

This pretty much confirms that we are getting 400-series motherboards with Intel's Comet Lake-S processors in early 2020. There are a lot of high-end options missing in the Z490 lineup which may be due to the fact that these are Gigabyte specific motherboards and not the AORUS series boards that carter towards the high-end gaming and enthusiast market.

Comet Lake-S 10th Gen CPUs and 400-Series Platform - Here's What We Know So Far

The Intel Comet Lake-S lineup would be branded as their 10th Generation CPU family. Featuring the 14nm++ process node and architecture that has been upgraded since Skylake, the new CPU lineup aims to offer better clock speeds and more cores to enthusiasts. While 8th Gen brought us 6 cores on the mainstream platform and 9th Gen brought to us 8 cores, 10th Gen will bring us 10 cores and 20 threads.

The platform would be able to support enthusiast 125W CPUs, 65W mainstream CPUs, and 35W low power CPUs. The socket will be different and mentioned to be LGA 1200. These are 49 more pins than the existing LGA 1151 socket so we can say goodbye to compatibility on current boards. Some key features of the 10th Generation line are listed below:

  • Excellent Multi-Thread Performance
  • Up To 10 processor cores and 20 threads
  • Enhanced core and memory overclocking
  • Intel Turbo Boost Technology 2.0

One big change to the platform will be the number of available PCIe lanes. Intel isn’t pushing the move to PCIe Gen 4 yet like AMD, but they are planning to offer more PCIe lanes compared to AMD’s Ryzen 3000 / X570 platform. The platform details mention up to 46 I/O lanes, 30 of which will be provided by the chipset. That means that the CPUs will still feature 16 PCIe lanes, but the PCH will boast a higher number.

There will be 24 PCIe 3.0 lanes while the rest will be powering different I/O channels. There is also support for Intel’s Optane memory on the LGA 1200 platform, so that is something to look forward too. The platform block diagram is also provided which seems to suggest that DDR4-2666 (native) compatibility will be retained. Expect to hear more details by Intel on their 10th Gen desktop lineup later this year with a formal announcement planned around CES 2020.

Are you excited about Intel offering 10 cores on their 10th Gen Comet Lake-S CPUs?
