VizzieTheViz even if it’s just PL2 that’s a lot of heat you’re dumping into a room. For gaming add a GPU that’s doing something similar in power consumption (or worse) and a monitor doing its bit and you’re effectively not gaming in summer without an AC going full blast. This seems kind of ridiculous by itself, and I’m not even thinking about the kind of cooling you’ll need for this to work well. I could kind of get behind it if you’re using it for work to make a living, but for gaming this seems insane. Reply
bit_user It'll be interesting to see what the perf/W curve looks like. Memory bottlenecks might end up doing more to throttle the CPU than power limits, in most heavily-MT workloads. Reply
usertests IIRC the 474W limit is only going to be hit by overclocked dual-tile CPUs, not out of the box. I'll look for a source. Reply
S58_is_the_goat Hey intel, please switch to a 12VHPWR connector instead, now the cpu and gpu will catch on fire 😂🔥 Reply
TerryLaze bit_user said: Most games don't scale well with core count. They're starting to do more of that, but you can get a pretty good idea by just looking at CPU power consumption while gaming to see that a lot of the cores spend most of the time idle. We don't know that and the graph you are showing isn't showing that either, you would need an infinite GPU to see if current CPUs scale in games or not. (or run games at postage stamp size windows) No review ever tries to show GPU usage during these tests to show anything (not that it would since a GPU has so many parts that can bottleneck). "We don't have GPUs that allow CPUs to scale very much in games" would be the correcterer thing to say, since we also don't know that for sure. usertests said: IIRC the 474W limit is only going to be hit by overclocked dual-tile CPUs, not out of the box. I'll look for a source. It's in this article: " It is important to note that these power limits may only apply to the top-end models with the dual-tile architecture."

It depends on if they keep the PL2=PL1="max wattage" credo, if they revert to what was before that then PL1 will be the power draw and it will only go to PL2 if the CPU budgeted enough wattage over the previous time span to boost up to PL2 without increasing the overall average. Also the whole article is "expected" "leaked" "may" and so on, nothing of that might come true. Reply
usertests TerryLaze said: It's in this article: " It is important to note that these power limits may only apply to the top-end models with the dual-tile architecture." Key detail being: overclocked. Not hitting that out of the box even with 48-52 stressed cores. Reply
TerryLaze usertests said: Key detail being: overclocked. Not hitting that out of the box even with 48-52 stressed cores. Since these are all speculations…does it even matter? If it's like previous gens, unlocked PL will be the same as the max overclock anyway and PL2 will probably be the max that every single CPU will be able to reach. Reply
JRStern Unless you're running six VMs so you have a complete copy of your server farm on your workstation, this all seems silly. Four performance cores and four economy cores should take care of 99% of what anyone does on a workstation (much less a laptop). With modern SSDs on the PCI that's already one buttload of computing power. Ditto graphics, really, OK game fanatics … whatever. I dropped out of that after Pac-Man. If I need more than about 60 watts on a workstation, just do it in the cloud. Reply
rluker5 Intel+W11 have gotten pretty good at managing hybrid cores. This Dual compute chip is new and will probably be sloppy at scheduling at first, and keeping both energized while only needing one should hurt light use efficiency. And performance by a bit. The single chip version won't have these issues. Maybe I'll be surprised and they will have it all worked out by release. Reply
