So, I replaced the thermal compound with PTM7950, installed TPFanControl and enabled Power Mode "Best Power Efficiency" (it appeared after some drivers update, I think?), and, sitting on desk, in Stable Video Diffusion Generation it goes to about 76 degrees, with memory to 82 degrees, it draws about 60W and the fans at about 3100rpm's.
The screen is without PWM, it came with some factory calibrated profiles. The sound is very good, compared with my ZBook G3 (maybe on par with ZBook G6, wich was better than the G8 I have), you can hear the instruments more separated and clear, it's way better.
The latencies are not the best right now, but the BIOS version is just at 1.1 and so I guess are the drivers.
No undervolting.
For video editing it is the best choice, 4K 10bit 4:2:2 are not a problem, similar to mac's, maybe even better.
Peronal preference, i liked way better the power adapter plug on the ZBooks; it could be twisted and rotated in any direction, even if bumped in it would just disconnect, and the interios plug was connected to the motherboard via a cable. This one has 3 type-C's, 2 on the back and one on the left and you can choose wichever you want to charge. But they are soldered into the motherboard (yeey for European Community 🤢🤮).
The keyboard and touchpad are very good, but on ZBooks they were not bad either (I miss the 6 bottons touchpad in 3D softwres navigation).
I'm not a gamer and I'm not interested in top extra fps's, I rather prefer silence, stability and low heat on long renders, so that is how I / it can be configured (I'm keeping the CPU limited to 30W in ThrottleStop).
The thing is that the cooling solution seemed to me more like classic heatpipes rather that vapor chamber, but I was not inspired to take pictured when I opened it. Maybe I'll do later.
For what I tested, it surpassed my desktop with i7 10700 and GeForce RTX 3070Ti in both CPU and GPU, by about 10%.
As I said, having 76 degrees and 82 on memory, with PTM7950 and not stock compound, I wouldn't want any higher power graphics, unless puttining earbuds on 😆. Onestly I had better expectations from the cooling, which has bigger air gap at the back and vapor chamber; it's not bad at all, the air sound iw more constant and nicer to hearing, but weirdly it does not surpass ZBooks G3-G8. Curious about the new 3 fan config on G1i.
The weght is just like ZBook 15 G3.
Overall I like it very much, it looks, feels, works like a powerhouse that it is, and I kinda recommend it!😊 Wish it was easier on the eyes, (it's not by far bad as others, but that might be from OS/drivers/SW counterpart - dithering and color enhancements 🤢)
