ThinkPad P1 Gen 5: Lenovo updates its thin & light workstation rather quietly to Alder Lake H

[Redaktion]

The Lenovo ThinkPad P1 G5 has been announced without a big show. Considering the scope of the update, a more opulent announcement probably was not necessary. since the new model is basically the P1 G4 with updated internals.

Probably quietly because it's an embarrasment intel 12th gen with 0 hours battery life.

I am very glad I bought the G4. Battery life is better on the G4 but it also has AVX512, which I find important for my workload.

This seems like a few steps back - poorer battery life and no AVX512 and no Xeon.

As I'm sitting here researching new laptops, I came across your comment and I'm curious about your usage of AVX512 on a laptop.

My understanding of AVX512 is that it's really geared more towards server workloads with some optimizations for AI and machine learning... and that it's also quite power hungry and can generate enough excess heat (especially in the context of a mobile CPU) that the system is forced heavily throttle the CPU to prevent it from cooking it's self.

so, what are doing on a laptop that actually utilizes the instruction set?
