AMD and Intel both do the same thing and TLDR: money.
Realistically though there's three main reasons we're seeing it:
- MTL was the first volume part from IFS using EUV while they were still installing machines in fabs so they'd have likely never had enough volume of MTL alone to cover the laptop market so we saw some RPL SKUs.
- ARL is using TSMC N3 which costs a lot of money so it makes sense that the lower laptop SKUs (unsure if there will be desktop or not) will be ADL/RPL.
- When it comes to ADL-N the cadence for enterprise is likely a driver. Crestmont isn't a significant improvement over Gracemont so it would make sense for Intel to be planning a replacement with Skymont/Darkmont. Given the generally low margin of these parts it would make sense that Intel would prefer to use their own fabs and/or a cheaper process to make them and they likely don't have capacity right now. I wouldn't be surprised if we saw either Skymont or Darkmont on Intel 3 as the new N SKU down the road.
