I'm honestly surprised AMD didn't launch desktop Rembrandt (on AM5) and B650 alongside the high-end stuff. It seems like it would have been an easy way to appease the budget conscious consumer.

DDR5 launched mid 2020. In a usual environment (no human malware, better performing competition) DDR5 would have been more widespread and cheaper by now and an earlier platform launch with Rembrandt would have made perfect sense. Now the platform first starts as a premium product, just like new Zen gens do since Zen 3.

Woah there buddy, wouldn't want to confuse the consumer with all those options!
It's probably just amd copying intel and releasing the halo parts a few months before the mainstream parts, both motherboards and cpus, hopefully, I know the zen3desktop "few months" was 20 months.
That and amd really doesn't need much stock to launch a high end diy solution while mainstream they need to be able to supply oems and walmart tier buyers.

As for waiting for a 6800 laptop with the design/spec I want it's just not appearing. Maybe the lenovo t14 but the price too high from what I saw last time.
I've given up and just bought a steam deck for now.
Phoenix cpus will have better designs and availability right?

I just got a Lenovo ThinkPad T16 AMD (16") - Black for $1,138.05 Its a 6850H I think ? Power brick says 65watt max, and it is charged through a USB 4 port. Directly from Lenovo. My 6800U was 3 months OOS. I think they are very close, but the 6800U was a few hundred less.

phoenix will likely cost significantly more than rembrandt and i have not seen anything which would indicate that it will have improved availability. maybe by the time it is launched those of of waiting for a 6800U will finally be able to purchase one at a reasonable price.

You would think it would have better availability simply based on its expected sheer technical domination. On the other hand, it's not a drop in replacement for OEMs so alignment with design refreshes could play a large role. That said, regardless of availability, we'll likely see a shift towards premium devices. Sucks if you want a budget powerhouse and don't care as much about the display. Great news if you want an XPS, Spectre, Yoga, etc.

because zen4 is on a new die while rembrandt is based on zen3 which has been around for a few years makes it likely that phoenix will have less availability.

Will you keep Windows on it? If not, can you run PES on it before you replace it? Much appreciated!
OK, I ran it. Something is wrong with the results. They are in the excel file ? Its says elapsed 1000 something else 1000, xx somewhere Its a lot of work to share, but I will if I have to, but something is wrong.

Edit: I figured it out. See the PES thread. power, 31watt and peak 51 watt.

Thanks for doing it! The numbers are great, especially for MT.

Will you be able to check out your 6800U laptop as well? Or did you already decide to return that one and keep this 6850H one?

It comes Friday, but I think its a 6800H. The original 6800U is still OOS, so I cancelled the order. I may be happier with the 6850H anyway.

So, my 6800H came yesterday, opened it today, and its WAY heavier than my 6850H, so I am giving it to my son.
Interesting how the drawn out Lenovo delivery drama finally came to a wonderful conclusion. Instead of 6800U, you ended up with two powerful 6850U (not H i think) and 6800H laptops!

A mini review with some benchmarks (GB5 and Rapydmark High using High Performance power plan please!) and comparison of both with pictures would be really nice!

For those outside the US, Lenovo is shipping (as in immediately) a 14" Yoga 2-in-1 G7 with the 6800U. CNC'ed aluminum body. Screen available in 60Hz 1440p IPS (300 nits, 100% sRGB) or 90Hz 1800p OLED (400 nits, 100% DCI-P3). Up to 32GB LPDDR5-6400.

Price for the maxed version is around 1600 euro/dollars (a bit more in the UK). The extra 16GB RAM is $200 and the 512GB->1TB SSD another $100. You can save $100 by stepping down to a 6600U, but you might lose the ability to order 32GB RAM.

The displays are pretty much identical in price. The are reports of issues with the digitizer being visible under certain conditions with the OLED variant, as appears to be the case with most OLED touch screens for laptops, from all major OEMs. Other displays might be available in retail.

This model had some significant BIOS issues initially, but they appear to have been fixed.

Not one I would personally buy without seeing and handling one, but it seems like possibly the best 6800U laptop right now, if you live in the "right" place.

Linux support is pretty bad out of the box, but everything except for the bass speakers and integrated mic apparently works with patches and should be mainlined fairly soon. Personally, that's a bit too bleeding edge for be, so I would hold off until everything I need is in place.

Acer just launched new Edge series with 6800U and 16-inch 4K display for US$1500. A little late to the party, and I can foresee this model will be best fit for Phoenix point refresh next year for around same price

wow, the first decent sized 6800U but that price! it's at least 50% too expensive imo

Dell has quite a few laptops with AMD 6 series Ryzen. I am typing this on a G15 with a 6900HX.

wow, what an underwhelming list-thanks for compiling it though. the only 6800U's abpve 14" are $1,500 which is at least $700 more expensive than they should be.

this lenovo is an example of exactly what i am looking for but with 6800U instead of the 5800U it has.

Other than the IGP I don't think you are missing much going with Barcelo. When you factor in DDR5 prices you can see why OEMs prefer it.

Yeah, I was just including the u series since it's been fairly elusive. On a side note how do you like your G15? I've thought about getting one.
The first one they sent me died after 3 days. That was disappointing to say the least. Took them 2 weeks to send a replacement. But this one has been solid. It's pretty heavy. Runs every game I've thrown at it just fine, though on demanding titles it gets hot and noisy.

i already have a 4500U so the igpu is the reason i am looking for a new laptop as a 6800U will run games far better than a 5800.

Supposedly, the 6600u should be slightly better than Vega8. I've seen a couple of those for almost reasonable prices.
it's not worth the upgrade from vega though. personally cost wise it would be better to go with a 5800U over a 6600u so really the 6800U is the sweet spot as far as prcie & performance for laptops imo.
