Intel Discontinues Several 11th Gen Tiger Lake CPUs

Intel has issued a product change notification (PCN) which discontinues various 11th Generation Tiger Lake mobile processors. The retirees include several SKUs from the Core i3, Core i5, Core i7, Core i9, and Xeon W line-ups. Tiger Lake launched between 2020 and 2021, so they aren't long in the tooth. However, the 10nm processors have become obsolete now that Intel has 12th Generation Alder Lake and 13th Generation Raptor Lake line-ups in the company's ranks.

The chipmaker isn't axing the entire Tiger Lake-H line-up. So far, the affected products are mainly Tiger Lake-H (45W) chips since demand has shifted to Intel's newer processor offerings. The discontinued SKUs range from the Core i5-11260H to the Core i9-11950H. Intel has included the Xeon W-11855M on the list. The Xeon W-11855M hexa-core processor is one of the only two Xeon Tiger Lake parts. The Xeon W-11955M Processor, which wields eight cores, is safe for now. There still seems to be some demand for Tiger Lake chips with IPUs (image processing units). Intel hasn't terminated models, such as the Core i7-11390H or the Core i5-11320H.

The 11th Generation Tiger Lake B-series processors, which feature a 65W TDP, have also reached the end-of-life (EOL) status. Intel had brought a couple of its 45W Tiger Lake chips to the desktop via the BGA route. Processors, including the Core i9-11900KB, Core i7-11700B, Core i5-11500B, and Core i3-11100B, were viable for vendors specializing in small form-factor (SFF) systems. Like the Tiger Lake-H chips, clients have until June 30, 2023, to put in the final orders, and Intel will ship the orders out before January 26, 2024.

A few months ago, Intel had bid the company's 11th Generation Rocket Lake desktop processors. So naturally, the writings were already on the wall that Tiger Lake wouldn't be safe from the next cut. There aren't many Tiger Lake chips left, so the 10nm family of mobile chips will eventually cease to exist. It shouldn't matter to consumers, though, as faster mobile Alder Lake and Raptor Lake alternatives are already on the market.

Intel's last client CPU to properly feature AVX-512. Not that it matters, for most of us.

I am not a fan of tiger lake, good riddance. I have the i7 u variant 1185g7, stupid thing is always boosting unintelligently, battery life quite poor and performance middling. Honestly I prefer my old 8th gen i5-8350u Lenovo T480. Battery was comparable(it had 2 batteries so probably not as efficient :D) and performance day to day was a tad slower but honestly I never heard the fan and it was a lot more stable. On my 11th gen I have weird issues where USB will stop working until I reboot, as well as a permanent sleep the computer will not wake from without a hard off. I am looking forward to an Alder or Raptor lake replacement in the next 6 months.

It seems like new computers are less stable than old, maybe its a Windows 11 + Corporate spyware issue as on personal machines I don't seem to have the these issues - but on personal machines I also don't upgrade but like once every 5-7 years :), so I don't have as much experience outside the corporate environment.

If you're running Windows, then I'd suggest you explore the power settings. If you don't might sacrificing a bit more performance, then you can extend the battery life a bit. Not only can you bias it towards battery life, but you can also limit the maximum boost.

My current work laptop is a Dell Precision with a i5-1250P, and I've not been much impressed with its battery life, either. Even with Windows Power Settings configured to favor battery life and the screen brightness set rather low, simple web browsing seems to drain it faster than I'd expect.

FWIW, it's still running Windows 10.

Yes, this matches my experience.
