Why not use AMD CPUs?

I read that the X1 was developed with Intel, and thus they can't use AMD CPUs in that lineup. I don't know if it's true or not. It was a random reddit comment.

Time. I saw the HP Envy on Linus' Tech-tips review and the battery life on AMD CPUs is ridiculous. 14 hours on battery. For most people, you might be able to bring your laptop to work WITHOUT a power brick.

I'm personally not a fan of HP laptops, but i'm looking forward to AMD CPUs on thinkpad and Dell XPS laptops. There is no way there isn't going to be a X1 type laptop with an AMD CPU. Lenovo can't leave that kind of battery performance on the table without losing market share to Dell and HP.

14 hours compared to 13h for a similar intel based laptop. Not really that impressive. Correct me if I’m wrong, but most of the power consumption comes from the screen anyways.

It's impressive for AMD - they have had a not so stellar history with overheating, battery killing laptop CPUs. Also that's with 8C/16T as opposed to 4C/8T on Intel.

Yup, only 7% better battery.

But... 20% cheaper. 50% faster in multi-threaded tests, 20% faster in single-threaded tests.

Almost seems strange they've kept that 522g battery in there, when they could have had ~10h battery life and a machine approaching a kilo.

This is likely a product of Project Athena. Intel is spending a lot of money codeveloping flagship laptops with OEMs. That, of course, comes with CPU exclusivity.

I'm guessing not enough time to stuff an amd rig into ultra portable form factor.

Their previous lineup did also include ultraportable AMD devices like the X390 though. Or is there something inherently harder about AMD designs?

I doubt it, but the nano is over 20% lighter, it's in a different class, a class that amd hasn't competed in until now.

I'm guessing amd will be in these kinds of ultra portables soon. Their cpus are flying off shelves, they're probably focused on the more lucrative server market for now.
