Question AMD Rembrandt/Zen 3+ APU Speculation and Discussion

[izaic3]

Alright, so we've had some leaks so far. I don't know if any of it's been confirmed yet, as it's pretty early, but here is what I've surmised so far (massive grain of salt of course):

• Zen 3 "enhanced"
• DDR5 and LPDDR5 support
• PCIE4
• 6nm
• CVML
• Navi 2/RDNA/RDNA 2
• 12 CU
• Socket FP7/AM5
• Possible USB4
• 2021(unlikely) -2022 (more likely) release date

If if turns out to have RDNA 2 and 12 CU, I could see iGPU performance potentially almost doubling over Cezanne.

If I've made any mistakes or gotten anything wrong, please let me know. I'd also love to hear more knowledgeable people weigh in on their expectations.

Ryzen 6000 Pro was just released.

AMD's new Ryzen Pro 6000 mobile chips are here for business laptops

Following the launch of standard Ryzen 6000 processors earlier this year, AMD has announced a bunch of new Pro counterparts with boosted performance, lower power consumption, and new security features.

so what is the difference between a 6850U & a 6800U? are these Pro versions just "special" vendor specific APU's with the generic versions to hopefully follow soon after?

AMD PRO CPUs come with more features for the Business.

AMD's Revolutionary Ryzen Phoenix APUs Could Mark The End of Low-End Graphics Cards, A Big Win For Budget PC Gamers

AMD's next-generation Ryzen APUs, codenamed Phoenix, could spark a revolution in the integrated graphics segment with huge GPU performance.

wccftech.com

interesting speculation about next gen APU's. may be worth waiting a year for 3D V cache & potentially RDNA3?

 

[Shivansps]

It depends of what you consider as low end... the 3400G was already outperforming GT1030 and RX550 in several cases. The Phoenix APUs are going to outperform Navi 24 for sure. RMB already has a chance, at least in a few corner cases.

I noticed the Gen4 L and E series thinkpads a few days ago and was distraught when they were just 5850s.
It doesn't look like rembrandt is coming to anything other than T series and more reasonably costed laptops from them are getting the shaft for another year.
Is there any good 6800h/s with no dgpu on the horizon yet?

Ouch, that's bad.

It's still early days regarding availability. Going by stocks in Germany ASUS seems to have effective early exclusivity. Currently the only model without dGPU appears to be ASUS ROG Flow X13 GV301RA containing 6800HS.

 

[ahimsa42]

i believe it has been mentioned here before that most of the H series laptops will come with a dgpu so it may be the U series which vendors will sell igpu only?

nice laptop if only would be without glossy display. considering coing from 4800H without dGPU laptop to this but that glossy display....

 

[moinmoin]

Yeah, that would be the natural sequence considering the U series targets a lower TDP, combining that with dGPUs makes little logical sense. OEMs still regularly did that in the past, but I'd hope that changes with Rembrandt and its improved iGPU.

Rembrandt is only going to appear in the higher end for the most part of the entire year. Similar story to Cezanne in that sense last year. It'll trickle down to the lower end next year, probably.

 

[izaic3]

Some benchmarks of the new pro chips. Let's hope availability isn't an issue...

I'm afraid it's no coincidence the first U series chips are Pro models. So we can expect those to be primarily sold from OEMs directly to companies equipping their employees, not to consumers on the open market...

Makes more sense than giving scalpers more hardware to buy and run up the price with.

Does that happen with laptops?

 

[Mopetar]

Does that happen with laptops?

There were a lot of mining operations that were using laptops because they were cheaper than buying a desktop card. The lower clock speeds didn't really matter for something like ETH since miners usually underclock the core anyway.

Edit:

Here's a link showing a large mining setup that was running off of gaming notebooks.

 

[jpiniero]

Hey, Dell finally has Rembrandt laptops available. By available I mean they don't ship until May and only gaming laptops with Ampere.

 

[HurleyBird]

Yeah, I'm seeing a lot of 2-in-1's with Alder Lake, and sub-DTR with Rembrandt. OEMs gonna OEM I guess.

 

[izaic3]

An interesting observation.

Why do you think this is? Wafer supply?

 

[moinmoin]

Not unusual so far, happened with previous gens as well. The big amount should come mid to late summer, at which point the clearance sale for the previous gen starts.

(Though the impact of China's current lockdowns may well delay things further compared to the last two years.)

Here's a video of igpu performance of a ryzen 7 6800U. Not much in details, though he does say that he'll review the laptop (which he doesn't say which in the description) in 8 days [Thumbnail looks like an ASUS laptop though].
TDP is 15-28W, though this particular testing was done on 28W.

 

[ahimsa42]

hopefully this is a sign of 6800U's finally showing up in laptops soon

One more 680M igpu performance review, featuring a 6900HS with max TDP of 85W.

If Rembrandt does come to desktop where such TDP can be sustained, it will be a nice CPU for SFF builds. (The performance of igpu may also increase with faster RAM)
It can be the budget oriented product stack for AM5 socket while the zen4 stack will be premium one.

Just watched a review of Asus Zenbook S 13 OLED, featuring the ryzen 7 6800U. Do you want me to post the video, or just the screenshots of graphs which show any improvement from the previous gen? (The video goes on for 16 minutes and is more oriented towards the laptop than just the processor)
