Question AMD Rembrandt/Zen 3+ APU Speculation and Discussion

[moinmoin]

Yeah, I'm sure a kickstarting company with the name AOKZOE is ahead of Lenovo in the chips delivery food chain. 🤣 I doubt it's anything more than gross stock mismanagement by Lenovo itself. Unless they always sell stuff they then can't deliver for months?

THATS where my laptop is, nowhere due to this ! Its 36 days over the original ship date, and still counting. (from Lenovo directly)

I see that Dell has Ryzen 6 series laptops in stock for next day delivery. A bit pricey and with gpus in them though.

The only ones I found were 6800H (mine is 6800U) and Nvidia descrete GPU for like $1600 or more. Mine is between $775 and $861, depends on if they give be the 10% off like they promised for the delay.

Oh, and they are like huge, starts at 5.5 lbs. Mine is 2.7 lbs.

Current prices of those few models that are available are bad, for the price of 6600h and gtx 1650 i could get 5800h and rtx 3050.

 

[LightningZ71]

I still want to see a laptop made with just a 6900HX and decent cooling put through it's paces. While I expect the 6800U will be a sterling product, I'm interested in how far the platform can be pushed.

exactly-to me, the sweet spot is the 6800U with igpu only as i don't really see the point of the other 6000 series since one can get a 5000 series laptop with a dgpu for much less $. that is exactly what i would do if i did not want an igpu only laptop.

Looks like AMD has finally figured out a good idling solution. Impressively low idle draw!

Im in that camp ... really want a yoga slim pro but the 6000 is a 50% premium over the 5000 model.
Think I am gonna pull the trigger on the 5800h model, they're actually really really cheap right now, probably cause of 6000 and 7000 being on the horizon?

Was in the same camp until 2 weeks ago, when I decided not to aim for 6000 series. The prices on 5000 series laptops are so much lower that it's hard to buy 6000 right now.

I ended up buying an Ideapad 5 Pro for a price that would be around $470 in the US. (metal build, 5600U, 16GB RAM, 1TB, 2.8K screen with 90Hz/400nits). The parts of the build that don't feel premium (touchpad, speakers) are irrelevant for me, the only thing I would have liked to be better is the cooling - fan speed is fine, fan pitch could be better. Overall it's much better hardware than what I would have expected years ago for the price, normally I used to avoid this price point due to obvious quality and reliability issues.

With this little money spent I can simply wait 12 months and buy another 6000 series laptop then if I really want to, the total cost will probably be same ballpark with a newer 6000 model bought today.

I guess I am in the minority. Much prefer a minimum of 17" screen and always disable the touchpad. The touchpad is a total waste of time to me because my hands touch it while I type. Too few laptops come with the little thumbstick IMHO. Don't mind touch screens for some stuff, but I will always lug a mouse around with me. Too bad they don't integrate some touch zones in the sides of the bottom corners that can be used to simulate dials and extra buttons. Throw in a motion sensor. Would like that as a way to play me some pinball.

Laptop makers keep pushing smaller, thinner laptops. And when they do go thick its always cheap, heavy, and poor efficiency. Doesn't make sense to me as they could work durability and thermals much easier in thicker designs. And thicker doesn't need to be a heavy ass brick. Wouldn't mind a nice 17-19" IPS built around metal framing that surrounds closed cell foam ribbing to absorb shock. Two pounds max. Virtually uncrushable when closed. Never hot on a lap. Ribbing makes it easy to hold when closed. Sturdy hinges. No need for touch screen. Build in a spot for parking a mini-mouse. If its a touchscreen, then put in spots for touch pins. Strong enough to set a bag of groceries on it without warping. Stuff like that honestly happens to people.

Maybe the AOKZOE thing is just a sign of Ryzen 6000 chips supply/delivery situation finally picking up? Eh
We'll know for sure soon enough.

and unless you are really wanting a better iGPU gaming experience there isn't much reason to get a Rembrandt over Cezanne laptop

Looks like Pink Sardine = Phoenix.

lets hope so! here is more positive news about DDR5 too:

Consumer DRAM Prices Expected To Drop 18% In Q3 2022

As shopper interest in PC slow down, DRAM costs are anticipated to drop by close to 18% at the end of the current quarter.

great-yet another awesome AMD APU that consumers won't be able to buy anytime soon if ever.

Apple M2 vs. AMD Rembrandt vs. Intel Alder Lake Linux Benchmarks Review - Phoronix



Apple was incredible in some tests but woefully behind in others. The safest choice seems to be Zen3+, in my opinion.

Sigh.

Once again: please be careful posting results of the Phoronix Test Suite. Lots of really odd edge case workloads in there. Best not to take the results too seriously, unless you're sure your workloads mirror that selected by Phoronix; furthermore, lots of that software isn't optimized for M1 or M2 at all. Pretty sure some of those benches haven't even been compiled for ARM.

 

[igor_kavinski]

Sigh.

Fair enough. I'll put a disclaimer below the results next time.

benchmarks have their place but how much difference would one actually notice between them in real life applications? for all but the most intensive applications perhaps a second or two at most?

for the vast majority of users who only stream video, webrowse and play games @ 1080p i think a 1050ti level APU will more than suffice so really it comes down to price & availability.

intel has great CPU's but trash igup's while apple software is extremely limited (especially when it comes to gaming) and the hardware is extremely expensive-which is why regardless of the benchmark comparisions imo AMD has by far the best all around APU products. now if only the most current generation was actually readily available to the average consumer at a reasonable price.

ComputerBase reviewed different laptops, both Intel and AMD. Please check It out.

What I found very interesting is the Rembrandt's IGP clock speed at different TDP and performance in Cyberpunk.


And here is the performance chart.


I don't understand why 10W 6800U with IGP clocked <600Mhz performs at 45% of Max(~67W) 6900HS, when that one clocks at ~2300 MHz, which is almost 4x higher.
The second thing I don't understand is why 6900HS 25W scores 10% higher than 6800U 25W, when It has ~15 lower IGP clocks?


edit: Ok, after checking once more, they are both dual channel, but one is using 6400MHz(6800U) and the other 4800MHz DDR5(6900HS). Mystery solved.
Even 45W is not enough for Rembrandt to boost to 2400MHz. It would be interesting to see what's the performance difference between 6600U 25W vs 6800U 25W.

I haven't read the ComputerBase reviews, but I have seen one review where a laptop with a HS series apu was tested with one stick of ram. And then you have differences between so-dimm and lpddr based laptops.

I don't believe that the Zenbook 13 has the greatest cooling either. At 25 watts, cooling becomes a significant factor.
