What a bummer... I was hoping for a Zen 3+ chip as an upgrade. I do not look forward to what BS the triumvirate of scammers (Micron, Samdung, and SK Hynix) pull off to screw us over on DDR5 prices making Zen 4 upgrades priced out of range for most people. I think my 3900X is at its limit, I got a real stinker as far as OCing it goes, aside from the Infinity Fabric which I have 100% stable at 1900MHz which is apparently not common. Syncing the Fabric/memory controller/memory at 1.9GHz really matters for game performance in the tests I've done... so I guess overall I got a good one?? Syncing the clocks at 1.9GHz mitigates some of the latency issues that cause performance loss in games, but it would have still been a nice upgrade getting a Zen 3+ chip considering I'm one of the 3.5 people on the face of the earth who managed to get an RTX 3080 before scalpers did.

If you look at Apples M1 obviously this design works for low power. The M1 is an excellent example of making really wide performance cores(way larger than Intel and AMD cores) then using little cores to provide extra threads. Intel's new big desktop CPU(APU) the 11900k has 6bn transistors and Apples M1(4 perf cores + 4 small cores) has 16b transistors. These densities of transistors will make having really powerful cores an option and it does look like in low power situations tacking on lower performance cores is a great option especially since said lower power devices spend a lot of time doing light tasks like web browsing, checking email, spreadsheets etc so you realize lots of power savings keeping those big cores powered down most of the time.

beat me to it. loving my macbook pro, wishing it had a fire-breathing gpu (cuz my need for nerdiness)

isnt simple multithreading already too much work for most devs? how would adding asymmetric multithreading help things? at least for complex single tasks like games, of course stuff like cinebench wont give a damn if its a pentium glued to a jaguar core but thats hardly of any use on desk/ws

big.LITTLE would be perfect if Windows managed to put the computer in a suspend state where it could still use networking and I/O in general, so you could download things or do simple file server stuff with the computer basically off. I also bet it would be great to assign all the background Windows stuff to your LITTLE cores and let the big ones do the actual work, without any thread jumping between tiles/CCD/CCX.

(we can imagine ASUS being very happy with that product codename) - lol someone in Marketing earned their salary 🙂 I wouldn't be surprised if they introduced something referred to as a "rest mode" or however along those lines (the phrasing can change to whatever suits it best) to encompass what you're talking about. Sleep and Hibernate may get reworked a bit or perhaps combined into more of a hybrid feature as opposed to two separate entire options alongside a lower cycling mode with some core basic functions offering the aforementioned. I don't want to assume (for all I know by "fire breathing" you may mean along the lines of an RTX Quadro 5000 or an RTX 3070 / 3080 laptop gpu) however - last I checked the MacBook Pro 16" Radeon Pro 5600M was relatively on par with the RTX 2060 Max-Q.

:) all my prev laptops have had an xx70 at minimum

The Windows scheduler needs to be updated to handle thread dispatch and assignment in a heterogeneous environment. A new system API will also be a good idea for the applications to be able to query for low-power cores. There are many light-wieght threads running in the background, that don't really benefit from powerful out-of-order logic or wide vector units in the power-hungry cores. Those tasks can be served as well by Jaguar/Atom derivates, not only saving power (leaving more for the big cores), but also die space. This is how the M1 Macs balance the power budget and achieve high performance in a full-blown, but still compact SoC layout.

Lakefield?

this is already possible.

I dont trust windows or other software to be able to direct workload to the correct cores. My brothers old AMD A10 CPU is detected as a 2 core 4 threads CPU in windows, therefore 4 core minimum software will not start and workload is favored to the 2 first cores, even though the CPU is a 4 core 4 threads CPU. If they can not figure out how a 6 year old CPU works, i have little faith in software to work on a 8 core 16 thread CPU with 8 small cores attached to it. When does work get transferred between cores, and the cache and memory handover is going to be a mess, people already complained about the AMD chiplet work transfer latency. My overclocked 1700 is already down to 0.5-1.5W at idle per core, i see no reason for ARM like cores at 0.2W on desktop, when memory, SSD, Chipset, USB headset, watercooling pumps, LEDs and even fans use more power then my 1700 cores already. The powersupply for the ARM part needs to be separated, because a 100-200W capable VRM is going to have too much loss, when running the ARM part at 0.1-2W power.

Future for DX12/Vulkan, advanced physics/AI will be 8C/16T.

quoted for truth but 6/12 is doing very well atm.just requires a lot from the cpu in most open world games.it's not uncomming to see them at 75-85% package usage,with individual cores spiking over 90%

On laptops this make sense , now about the optimal configuration 4 8 no ht ...or with ht or 8 16 .....etc etc , no clue witch is the optimal one. If i had to make a bet would be the optimal for now would be at least 8 big cores and 4 or 8 little , mostly because the software will need time to catch up. I was way more sceptical but the m1's performance on video editing considering the power consumption is astonishing , but part of the fast performance is that apple has a locked ecosystem and put in the work to optimise it so first impressions are positive. Now the pc market i have no faith that things will work so well from the get go. I believe it will take at least few transitional generations. My 2 cents at least and i would be happy to be completely wrong and when those things come out find my jaw smacking the floor from the surprise !

Looks pretty concrete

You mean Modern Standby? Even if the platform supports it, I'm not aware of any software that supports it in the way I mentioned.

Fox2232:

When "platform" is mentioned. Isn't PS4 capable to DL updates while it is in rest mode?

Ah, no, I basically meant Windows, he either means Windows with whatever software supports Modern Standby. But you're correct about the PS4. The dream would be that the OS could flag apps that would work in that mode, and they wouldn't even know what happened. Zen 3 supports Modern Standby with the latest AGESA, but you need to format from zero to have it enabled, and it also depends on the motherboard.

not sure about having to format, the windows kernel is highly adaptive since 8 and 10's enhanced it further to the point you can drop an SSD from a phenom II into a system with a 11900k and reconfiguration of the machine is all automated. Its true that theres very little software support for modern standby, and probably the same amount of hardware support for it, its highly unlikely a thing you would see HDD's support, but M.2's which are powered by the mainboard would.

You're right in general, but this cannot be done like that according to Microsoft themselves.[/spoiler]

Fox2232:

It also means technological know-how exists for quite some time. On PC, all we got till now is WOL which means network interface does not sleep and keeps IP and is able to respond.

Yeah, it's kind of pathetic to be honest. Although things like mixed standby can actually flush memory contents to disk for when a laptop is on standby for longer, which means I/O is there. Intel Macs also can use the network while in standby, so I think the limitations are more on the UEFI/OS side, rather than the hardware itself.
