The old part really does a lot of work here. New ThinkPads are utter trash :-/
I got excited to get one for work (having heard about the old ones) and was sorely disappointed. It thermal throttles if you look at it wrong, it keeps having BIOS issues with Lenovo being no help and the USB-C display connection (To a Lenovo monitor with their inbuilt docking station!) is iffy.
Which series? T/P or one of the economy options? The T, X, W, and later on P series have been the only models people really like.
We have a few T series at work and they’re not bad. My T14 Gen. 1 doesn’t thermal throttle at all as long as its thermal paste isn’t toast. It will run at basically its full all core boost speeds all day long. The newer 12th Gen. machines dial their clocks back a smidge under full load, but that’s because they have 2x the cores of my measly 10th Gen. machine.
Also I have a T14s AMD and that thing is a BEAST for such a small machine. 35 watts out of an AMD 6 core is no slouch for something that small. And I easily get 7+ hours of battery life out of my abusive use.
I have two new P1 Gen 7's coming today, i hope they have fixed that
They didn’t. They did kinda change the goalpost though.
Which model did you get? The i7 or the i9? The i7 models have a minimum guaranteed TDP of 28 watts, while the i9 is at least 35. But 35 watts on such a high end CPU is dire. The Gen. 7 also killed their high end GPU options, but maybe that leaves more power headroom for the CPU.
That’s still better than my P1 Gen. 4 which throttles down to 25 watts. 25 watts on an 11th Gen. i9 is AWFUL performance.
i9 with the 4070 GPU
Let me know how the thermals are on that machine. I ended up paying out the ass for a refurbished gen 6 because it comes with the 4090 and a MUCH bigger heatsink. From what I saw initially in the reviews the performance is worse not just because the 100 series has worse IPC, but the machine doesn't actually boost as much since it's more thermally limited.
HOWEVER the machine gets a LOT better battery.
My gen 4 would get anywhere between 30 minutes and 2 hours of battery life unless I'm doing literally nothing on it. This gen 6 gets like 4 hours unless I'm heavily taxing it. But from people online I saw them say 7 hours is easily doable. And having a GPU that doesn't use 20 watts sitting idle sure helps.
Anything specific you'd like me to test?
The only thing I'm really curious about is how far back the CPU gets throttled with the dGPU active and busy.
On both of my machines when I render a video using my GPU the CPU is still the limiting factor because of the codec I chose. On my 11th gen machine it took like 5 minutes before it was power throttled down to 25 watts. My gen 6 takes longer to power throttle and only goes down to 35 watts, but either power level that sucks. I already know the gen 7 dials back the clock speeds, but I'm mostly curious how far it goes and how quickly?
The easiest way to test this is just open a video game that's taxing on the CPU and GPU, I don't think the CPU throttles with light loads like if you opened furmark. Maybe benchmarking software would cause it to throttle.
I was just blaming the usb-c connection to my monitor and throttling on a combo of windows and corporate bloatware, I guess I feel a bit better that I'm not the only one.
The connection to my monitor is the most frustrating, sometimes won't even recognise it, sometimes after blanking the display it'll come back with the wrong resolution but still display like it was the original, it's super bizarre. Literally never had an issue with my personal Asus zenbook in either Debian or w11.
