Sadly no M2 comparisons (I know they are a Linux site)

The initial AMD announcement included some comparisons, for example "AMD also included battery life benchmarks comparing the Ryzen 7 Pro 7840U against two Core i7 models and the Apple M2 Pro, with the former both having a battery capacity of 54 Wh, while the latter had a 69.6 Wh battery. Meanwhile, the Ryzen 7 Pro 7840U system was equipped with a 51.3 Wh battery yet managed to deliver longer battery life than all thr…

"AMD says AMD is the best." Wow, I'm so surprised. I also think I am the best(/s).

I still find this compute per watt thing such a silly thing for any company to care about. Until Apple did it, it was not on anyone's minds. Once Apple did it, they dumped a bunch of money into marketing a metric that no one cared about; and now people pretend to care about it.

Not to mention this obsession with CPU that I just cannot grasp. Not sure what industries this is the bottleneck.

So when are Lenovo Thinkpads with such chips coming out?

Can anyone explain why so many people want this?

If I am running a beefy single threaded or multi program with CPU, I want the best, not some low power device. Gaming laptop.(Or whatever we want to call it)

If I'm running consumer/enterprise software, I likely want a beefy GPU. Gaming laptop.(Or whatever we want to call it)

If I'm taking a 7 hour bus ride in a bus without a 120V outlet, I want this.

If I'm taking a 6 hour bus ride in a bus without a 120V outlet, I want a gaming laptop.(Or whatever we want to call it)

What is the use case? I got a feeling these companies are chasing Apple's insignificant metric of compute/watt, which doesn't matter as far as I understand.

I hope this processor finds it's way into a miniPC such as the ones sold by Beelink or minisforum. Having a quiet but beefy tiny desktop with 8cores/16threads tucked away out of sight would be a superb machine to have, and would also make me consider ditching any laptop.

They both already have models with these chips. Check out UM790 from Minisforum

Oh thanks for pointing this out! I completely missed that, but a quick googling led to a couple of reviews posted just a few days ago.

Very impressive machine, and quite affordable. Bonus points for Minisforum for offering barebones versions.

Earlier quoted context omitted.

This is true, but nonetheless many computers are guaranteed to work only up to an ambient temperature of 35 degrees Celsius. In my opinion, this is an incredibly stupid design choice. After being once caught by surprise, now I check carefully for a specified working temperature of at least 40 degrees Celsius, whenever I am buying any laptop or desktop computers. This, for example, disqualifies all Gigabyte small comp…

As long as you need reliability and are willing to discard all aesthetics, just go for a Thinkpad..

Just checked the Lenovo PSREF for my MIL-STD-810H certified Zen3+ Thinkpad:

Operating Environment Temperature[1] Operating: 5°C (41°F) to 35°C (95°F) Storage and transportation in original shipping package: -20°C (-4°F ) to 60°C (140°F) Storage without package: 5°C (41°F) to 43°C (109°F) Humidity Operating: 8% to 95% at wet-bulb temperature 23°C (73°F) Storage and transportation: 5% to 95% at wet-bulb temperature 27°C (81°F) Altitude Maximum altitude (without pressurization): 3048 m (10,000 ft) Notes: 1. When you charge the battery, its temperature must be no lower than 10°C (50°F).

So if you're in a really hot climate that might not be enough. Rn it's 31°C here in the shadows and idling SoC temperature is ~45°C.

The sheer audacity to claim no one cared about perf/watt before Apple. More like you did not know what it is before you consumed Apple marketing.

Why would you want a beefy GPU in anything except a gaming laptop or full blown workstation replacement?

Also on the bus ride. I certainly wouldn't want to unpack a 17" gaming laptop on a bus of all places. You couldn't use a external mouse anyways. There I'd want a steam deck or Nintendo switch.

Poe's law strikes again.

This is too on the nose.

Still waiting for my amd framework Laptop. They said early Q3. It would be the perfect machine for some nice summer coding on my balcony :*)

I’ve been annoyed they can’t provide any updates. How hard is it to provide a few sentence update every week like they do with the 16
