It'd just be nice if integrators like lenovo wouldn't nerf things like displays. It looks like their lineup for AMD mobile graphics is going to be significantly different than the Intel counterparts.

For real! What's up with the lack of 2-in-1 AMD x13? I have an artist friend who needs a new laptop and I'm telling him to wait for Ryzen 4000 laptops. Am I supposed to tell him to get a gaming laptop or something? These recent Intel laptops often have really dicey real-time performance because of how aggressively their clock speeds are controlled. For someone who does mixed multimedia work, a Ryzen 4000 2-in-1 would…

The announced Lenovo Yoga Slim 7 might tick the right boxes.

Except they're actually not. I would love to buy one, but there is no one laptop with 4000 series in shops here, in EU.

Yes the whole supply chain is somewhat having a bumpy time, it will get there in the end.

But had a quick look from the UK and plenty here for next day delivery.

Even some fancy ones like: https://www.amazon.co.uk/Zephyrus-GA401IV-GeForce-Graphics-W...

So technically they are available in the EU, just a slowly transitioning supply due to logistical human malware factors comming into play.

A better article here: https://news.ycombinator.com/item?id=22599598

All the current articles are terrible, because none of them have independent benchmarks. Apparently, no-one got review units in time because of all the disruption, but AMD went ahead with dropping the embargo anyway.

It's a laptop chip. Due to thermal throttling variability and all the ergonomic factors, reviews only make sense in the context of a whole retail laptop you can buy. You aren't going to buy a laptop and then choose your chip separately.

They mention Linux at least once in the article. That's always good to see.

Patches for Renoir based APU's appeared in kernel 5.4[0]. Looks like by the time these launch they will have out of the box Linux support which is huge compared to how Raven Ridge launched.

This is a really good point. Modern CPUs remind me of home internet with maximum speeds advertised even though pragmatically it isn't anywhere close to what people will get. Laptops, Intel NUCs, AMD desktop APUs, etc. all take a huge amount of BIOS tweaking at least to make them run hotter before they throttle, use less power, and possibly disable temporary clock speed boosts that heat up the CPU too much and make it throttle. Anything in a small enclosure seems to be an exercise in optimizing heat.

More airflow, lower max clocks and higher throttling temperatures make a massive difference on the set ups I've worked with.

So Anandtech has this to say about Thunderbolt 3 support:

"Display support for the CPUs allows for two 4K monitors through DisplayPort over Type-C, an additional 4K monitor if Thunderbolt is used, and a fourth monitor if USB 4.0 used. AMD has designed Renoir to not need additional chips to detect which way a Type-C is connected – that is all handled on die. With the display and USB support, the processor allows for concurrent USB 3.2 and DisplayPort use, with the peak DP v1.4 8.1G HBR3 standard in play using display stream compression (DSC)."

Which begs the question what does in-built mean? The Showcase Notebook Lenovo Yoga Slim 7 does not include USB 4 or Thunderbolt 3 so these modes will probably need additional chips.

...i want this 8-core chip with 32GB of LPDDR4X in a 13" Notebook that has 2 Thunderbolt 3 Ports and a matte Full-HD Touchscreen.

I'm not sure if my next laptop purchase is going to be an AMD one because I haven't got enough data yet, specs, benchmarks, etc. But I know one thing for sure, I will exclude from my shortlist any OEM that does not have a serious AMD based lineup. If they only have 1-2 models, or only in the low cost segment just to tick a box, I will be looking at other brands. I can't help but remember Intel's practices in the past…

In my case, I'm in the need of a new laptop this year, and I'm explicitly waiting for an AMD Ryzen.

I don't even care about the performance to be honest, I'm sure it will be adequate and I simply don't want Intel anymore.

With all the mitigations applied, I've lost the performance gain of the last two Intel laptop generations I had.

The integrated intel gpu is ok performance-wise, but being on linux I'm also tired of their development model: there's a fresh new driver/engine being developed every year, and it always buggy. It's true that intel always gets the latest kernel features first, but by the time is stable and it _works_, it gets deprecated in favor of a new buggy one. Way to go!

I've been using top-of-the-line lenovo laptops for a decade now. This has been the same every year, year after year, and I'm tired.

Isn't it more like AMD dropped the embargo (partially) because Lenovo, ASUS and others wanted to get their devices out?

Where can I read more about these kernel / driver related regressions of each revision?
