Intel has begun plans to discontinue its 300-series chipsets, including the higher-end Z390, Z370 chipsets, as well as its longer life B and H series chipsets. The 300-series chipsets are based on the second revision of Intel's LGA1151 socket designed for its Coffee Lake processors.

In 2017, to complement the launch of its 8th generation Core i7, i5, i3, Pentium, and Celeron Coffee Lake processors, Intel unveiled its 300-series chipsets. This includes the Z390, Z370, B365, and H310 chipsets. The most notable processors for the 300-series are the Core i7-8700K and Core i9-9900K, with these chips serving as Intel's flagship desktop processors from the end of 2017 up through the spring of 2020.

But Coffee Lake's time on the market is getting ready to sunset, and thus so are the chipsets that support it.

Outlining its discontinuance plan until the last shipping date expected on or before January 28th 2022, Intel advises its customers to make its final orders by July 23rd 2021.

Perhaps one of the most critical elements of the end of life plan is the H310 chipset. This is a chipset designed for longevity with three variations, including H310 and H310D based on 14 nm and the H310C built on 22 nm. It could be that the H310 chipset wasn't as popular as expected, especially compared to the H81 chipset, which lasted over 7 years before it was discontinued.

The Intel 300-series chipset has since been replaced by the 400-series desktop chipset, including Z490, W480, H470, B460, and Q470. These chipsets introduced support for Intel's Comet Lake (10th gen Core) processors, and their associated LGA 1200 socket. There have also been many rumors circulating that Intel's latest 500-series chipsets will be announced during CES, with Intel finally offering PCIe 4.0 with its new 14 nm Rocket Lake processors are expected towards the end of Q1.

    This article was either written by someone when drunk or by someone new at Anandtech who has no damn clue about the subject at hand.

    And on a side note, discontinuation of the 300-series platform is a bit sad. Now i don't know how much support we were getting out of Intel but in my case, Gigabyte has proven to be one of the laziest OEMs when it comes to board BIOS updates and whatnot. And it's the second time i've been duped by them. I don't favor AMD due to personal reasons but the more this shit happens, the more i feel pushed towards them.

    I have only used Gigabyte - and have no had an issues - especially with BIOS for say the 370 to allow Coffee Lake -

    sad that you see yourself as duped ...

    No problem with Gigabyte providing BIOS updates for my current AX370 Aorus Gaming 7 or previous Z370 Aorus Gaming 7. Quite prompt, in fact.

    No issues here with my gigabyte z390 ultra. Rock stable with all the features I paid for.

    Umm, 400 series motherboards aka LGA1200 are not Coffee Lake... they’re comet lake, and some will support upcoming Rocket Lake. Please correct.
  • Deicidium369 - Wednesday, January 6, 2021 - link

    ALL will support Rocket Lake- whether the board is built well enough to allow for PCIe4. My path was always Rocket Lake - so planned on waiting for the Z590s. Most boards will support PCIe4 on Z490 - Esp from major manufacturers - Gigabyte, Asus, etc.

    That's why pcie 4.x boards (and/or Thunderbolt 4.x) and compatible chipsets will stay longer on market and updating cpu's will be a benefit market until ddr5 (and ecc) appears on consumer level mainboards? That needs a 3-4yrs periods rewarded recycling market for getting consumers on that pace?
    400series will then be discontinued around 2024/2025?
  • Deicidium369 - Wednesday, January 6, 2021 - link

    Well since Alder Lake will take a LGA1700 board - and will be the main platform - and the 400 series will be phased out - 3-4 years support for a platform is about normal.

    DDR5 will only be of benefit immediately if you are locked into JEDEC 3200 DDR4 - if you are on high frequency memory (4000+) then the 1st gen DDR5 will be at best a wash.

    Intel marketing on their own language about their Evo® platform:
    "Verified to Blow You Away
    New 11th Gen Intel® Core™ processors and Intel® Iris® Xe graphics work together like never before to help you edit photos and videos 3 times faster than a 2-year old laptop"

    should be something added to this?
