AMD Hybrid Phoenix APU Comes With Performance and Efficiency Cores

According to the latest leak, AMD's upcoming Phoenix accelerated processing units (APUs) could feature a hybrid design, featuring Performance and Efficiency cores. While there are no precise details, the latest AMD processor programming guide, leaked online, clearly marks these as two types of cores, most likely standard Zen 4 and energy-efficient Zen 4c cores.

These two set of cores will features a different feature set, and the latest document gives software designers guidelines. Such hybrid CPU design, similar to ARM's BIG.little architecture, will allow AMD to be more competitive with Intel's similar P- and E-core design, allowing it to achieve certain performance levels while also maintaining power efficiency.
Last week, AMD's alleged Phoenix 2 APU has been spotted with such hybrid design, but the recent leak suggest that such similar, or same design, could be coming with AMD Phoenix APUs that are coming this year. AMD's Zen 4c cores were only mentioned with AMD's EPYC "Bergamo" CPUs, so it is quite interesting to see them implemented in other market segments as well.

I only hope this will not come to the high end desktop. Hybrids are for laptops and lower power computing not high end. I hope AMD does not drop work for 16c32t desktops processors with increased performance to compete with whatever competition brings along.

Technically AMD could follow the ARM route & go with big/little/huge cores with zen4c/4 & 3dvcache cores all on the same chip! Just like Cortex X/A7xxx/A5xx cores we find on top end chips these days.

Cool! New CPUs can’t wait to see how these perform and how much they cost

JismAll you need to do is to watch the motherboards QVL list. If you stick to that it's guaranteed pleasure.
Oh yeah nice if you can do that but here in Gougelandastan (NZ) you're limited to whatever the shops have in stock which is usually the cheaper Hynix die ram variety and the only 4000MT ram available here when I bought it was just that GSkill RipJaws F4-4000C18-8GVK x2 kit of 16GB which isn't mentioned in the Mem QVL but neither were any of the kits on it here

Well, okay, we're mostly talking about SoCs here, so hardware for very low power systems. This is a different niche and any concerns expressed in previous comments about lagging or even regressing in hardware development for high performance laptops and desktops are unfounded, at least for the next 3-4 years. :)

Not really, I bet Sony/MS choose these hybrid designs for their next gen consoles ~ whether something like Zen 5c/5 or even x3d cores. The fact that they're only differentiated by their caches is a big plus IMO, there's so many possibilities now!

Given how few cores have been described in leaks so far, I doubt that's the case.

R0H1TPretty obvious that hardware schedulers aren't that big of a deal as we saw with ADL or RPL, we've had similar programs on windows for eons like Process Lasso. Just get the OS, or dedicated software, to handle the scheduling & all's fine.
Pretty obvious they are though, as you’re seeing with the 7950x3d. No one outside of us nerds is going to process lasso their entire OS, and no one is going to want high performance threads running on the weaker cores….

Imo they have these density cores for server chips (where they will be awesome) but I don’t think the first gens of these on consumer desktop is going to be all that great.

7800x3d on consumer is probably the most interesting chip atm.

I mean outside of nerds or the really well informed folks the likes of 7950x3d or even high end Intel chips aren't needed much by the regular joes.

As for gamers frankly I think x3d chips are also OPed for their needs

haha, all of my AMD friends talked all kinds of about Intel hybrid architecture, yet here we are.

I wonder what kind of support the hardware has to tell the OS scheduler what to put where.

trsttteThe surface line up (the tablets I mean, the actual "surface", not the laptops that share the brand) have been craving for a solution of this type, the current (and previous) Intel iterations really do the name and form factor a disservice.



Since you mentioned the 2P+8E what do you think about them and the rest of the Intel line up with 4p/6p+8E (28w p-series) and 6p+8E ("45"w h-series)?
My only experience with them is with LG Gram laptops. The 2P+8E i3-1220P is amazing for the typical non-multitasking jobs you need an ultraportable for and the "TDP" never feeling slow or underpowered, and never getting hot or nuking the battery runtimes.

I've not dealt with mobile versions of Alder Lake outside of those LG Grams, simply because AMD laptops have considerably longer battery life outside of the Intel-only limitations of "it has to be an LG Gram".

If I'm buying laptops, it's usually ultraportables where battery life, performance/Watt, and IGP driver compatibility with CAD software matter immensely. Zen3/TSMC 6nm runs circles around Alder Lake/Intel 10nm7nm and the Xe graphics drivers present numerous issues where the AMD graphics drivers do not.

ThrashZoneHi,
Intel's desperate
AMD not so much
Why depend on win-11 to optimize big little nonsense
Most normal people reduce background crap anyway so little is not needed.
You don't hang around normal people, do you? :roll:

Hi,
Most people I hang with just use cell phones for everything pc's are way to much waste in their minds which gpu wise I can't argue with that and the fact eolake is a fact of life lol

But they still kill crap they don't need to save battery life ;)
