AMD's Ryzen 6000 mobile CPUs (codenamed Rembrandt) were announced and launched over four months ago in January and February, but it appears mainstream adoption has been slow for the new CPU lineup. According to ComputerBase, only eleven notebooks are actually using AMD's new mobile CPUs right now in the four months that have transpired since launch.
Out of the eleven notebooks released with Ryzen 6000 parts, eight of those systems come from Asus, with the remaining three coming from Razer, Lenovo, and Alienware respectively. That makes Asus by far the most dominant manufacturer to use these new CPUs, with Razer, Lenovo, and Alienware only producing one SKU each with AMD's new hardware.
The situation is strange considering Rembrandt can, in theory, go toe to toe with Intel's new mobile Alder Lake CPUs depending on what performance figures you are looking at. Rembrandt comes with AMD's new Zen 3+ microarchitecture that operates on TSMC's 6nm node. Performance is promised to be up to 1.3X faster than Ryzen 5000 mobile while being more efficient at the same time, with as many as 50 new power management features added to the new architecture.
According to AMD PR slides, all these improvements culminate into a 2.62X performance per watt improvement over Alder Lake processors (AMD specifically targeted the Core i9-12900HK and directly compared it to its own Ryzen 9 6900HS).
In testing with a ROG Zephyrus G14 equipped with the new 6900HS, we found Rembrant's performance to be quite competitive with laptops equipped with Intel's i7-12700H -- like the Alienware x14 and Gigabyte Aorus 17. Single-threaded performance was found to be on par with the Alder Lake counterparts, with the 6900HS primarily losing out to the 12700H in heavy multi-threaded workloads. However, this is to be expected considering the 12700H has more physical cores (despite the additional cores being E cores).
But most impressive results come from the battery life tests we conducted. The 6900HS-powered G14 managed a whopping 10 hours and 14 minutes of battery life. While the 12700H counterparts could only reach 4 to 5 hours respectively.
So despite Rembrandt being weak on the multi-threaded side of the equation, it remains very strong in single-core situations. While consuming far less power as it seems with our G14 review. Arguably, these two attributes combined make a superior gaming laptop anyways, since games are more sensitive to single-core IPC, and long battery life is a welcome sight for any device that is designed to be used on the go.
So there are positives for laptop manufacturers to use AMD's new CPU architecture over Alder Lake, but it seems almost no one is taking advantage of AMD's potential. With the exception of Asus.
Ryzen 6000U Series CPUs and Radeon RX 6000M GPUs Are Completely Missing
But the story doesn't end there. ComputerBase also notes that AMD's entire lineup of 6000U series CPUs is completely missing from the retail market, with zero laptop manufacturers using the new chips at all. The same goes with AMD's Radeon RX 6000M lineup of GPUs, which are all clearly absent from any gaming notebook on the market today.
The only exception to this is AMD's Radeon RX 6000S series products including the RX 6700S and RX 6800S. These GPUs are commercially available in the Asus ROG Zephyrus G14, like the one we reviewed not too long ago.
Arguably, availability problems could be related to TSMC and AMD more so than the laptop manufacturers. We've known for a while that TSMC is one of the busiest fabs in the entire world, and has struggled with providing enough wafers to its customers in a timely fashion, including orders going to AMD.
Intel, on the other hand, does not suffer from this problem since it builds everything in-house and owns its own fabs. If anything, it seems Intel has too much fabrication firepower on the table, now that the company is agreeing to produce chips for other companies.
However, these theories are just that — theories — as AMD has been silent on the matter. But hopefully, we'll know more information on the problems soon. AMD plans to bring Zen 3+ to the AM5 desktop platform later this year, which should hopefully lead to a new announcement discussing Zen 3+ further with more announcements related to OEM integration.

Indeed, one can only wonder just how much backroom shenanigans must have been going on, or how deeply the TMSC order book pipeline must have been blocked with lesser chips.Reply
I absolutley adore the Cezanne 5800U notebook I own: It puts everything Intel 14nm to shame and hardly ever breaks a ...fan (ok, my 5950X ain't bad either, but it does require a Noctua to keep quiet).
No, even an RDNA2 iGPU won't likely convert 15/28 Watts TDP into a gaming console, but who won't take the extra iGPU punch, if it came for free, and including tweaks in general power management, right?
I can only conclude that there is absolutley nothing wrong with that chip's design, but tons broken with how worthy chips get allocated foundry capacity.
Luckily, I don't think that it will break AMD's back, because the R6000 are little more than a shuffle of assets that AMD already monetized elswhere (including the Steam desk...). But darn, wouldn't I still like to have one of them, if my 5800U wasn't already much better than what I need for most everything I use it for.
And for the other stuff, I got them big iron with near Kilowatt dGPUs anyways...
AMD have a history of rejecting OEM deal.Reply
I've been waiting for these apus that are supposed to be so good. Really annoyingReply
And would you also know why?renz496 said:AMD have a history of rejecting OEM deal.
Is it because they are used to get so much contra revenue goodies from Intel that they can no longer operate at paying for CPUs? Or is really AMD asking for something unreasonable? And why would that change significantly from Ryzen 5000 to 6000?
While it may very well be true, it just doesn't sound very plausible in a scenario were supplied were not terribly constrained.
When AMD is all out selling wafer capacity on EPYC servers instead of low-margin notebook APUs, I could understand: bottom line is kinda important.
It was a long time ago during Rory Read helm the company. Also when it comes to things like laptop AMD, intel and nvidia did not simply sell the component to OEM. when they win the design win they also have to share the R&D with OEM developing those product. AMD is not like intel where they can easily make 18 to 20 billion per quarter. So in the end they need to be selective on which design win they want to fund. And ever since AMD go fabless intel probably no longer need to bribe OEM into not using AMD parts. AMD simply having hard time to fulfill their various product demand with limited capacity they can get from TSMC.Reply
Not surprising when you don’t have that much output to feed everyone. You will then have to prioritise who gets your chip first by looking at the sale, and, if they are going to be good strategic partners. Companies like Dell are more Intel aligned, and likely to be left as the last.renz496 said:AMD have a history of rejecting OEM deal.

This is the kind of insight that the press doesn't seem able to report upon, but which is crucial to both consumers and investors to gauge the market and base purchasing decisions on. I'll freely admit that my personal interest is on technology only, but today politics and economics are much bigger factors then tech... and quite underreported.
