Yeah but that’s not surprising. Google support MTE too, and I don’t think QC does even on flagships. They also have a 16kb page size Linux kernel / Android version you can flash to a Pixel, and Android 15 now supports 16kb pages explicitly and encourages developers to add support with the...

Honestly I was more underwhelmed at first with the 3500-3600 stuff and SME, now we’re seeing 4000, which implies some very different stuff.

Agreed. It’s a mess. They have small Korean AI customers but that’s almost like a handout, might even be subsidized and it’s just on 4NM (SF4X). Similarly AMD is only doing one cheapo Zen 5 4c part on SF4X. So after 4 years of playing around with 5 and 4nm, and really the 4nm only started in...

They just changed some things about the body of the laptop with the savings. Doubt it’s about some grave increase in cost from VRMs lol.

The second gen process of 3nm that doesn’t offer much difference from the first is now called SF2. Should be +22% perf and - 45% power over their 4nm standard node. The trouble with that is that their 4nm node sucks, and is like 10-15+% behind on perf still or -25-35% on power. The next 3nm...

Agreed

Intel 7 is not actually cheap, and it could be an X Plus (which for now is the X Elite die but binned down) they’re comparing with which also makes sense. One thing I think we can say fairly confidently is the AMD and Intel guys (yes here too) who thought Qualcomm was going to try and pull the...

No that was bull. Charlie Demerjian just bs’d lol. QC probably does have quality standards but the rumor was forcing them to buy QC PMICs which they explicitly said is not true in October. Also the chip is 170mm^2 and there’s an even smaller X Plus die still coming (not the current X Plus ones...

Beat me to it by a few seconds

Intel has AMX on servers, not client parts. Different class of extension. And GB I doubt supports it.

https://browser.geekbench.com/v5/cpu/22477137 So based on GB5, where the M1 in a *laptop can score 1730-1740 at the high end* (M1 Pro/Max 1800 but that’s also bigger thermal capacity and diff chip to a degree, faster ramping probably), and we have a 2714 GB5 from *an M4 iPad* the IPC gain is...

I bet power went up slightly, and I also bet it still blows everything else out. ??? It has nothing to do with that, that’s marginal at best. Apple does not make more from the app store than hardware, what in the world are you talking about dude. They don’t want to build drivers for it and...

Oryon, possibly with some physical design modifications they couldn’t get on time for PC stuff since it came later, plus it’s on N3E. Also pretty positive they’ll have a bigger SLC (and/or L3 but probably just SLC) on a phones chip (as Apple do too) which will keep power down. So 2 N3E Oryons...

They said they have more power gains vs M2 than they stated for the M3 - specifically 50% or whatever — but in MT, which is enabled in part by 2 more E Cores and an extra - 10% power from N3E (over N3B). They already had like 20-30% or whatever from the M3 over the M2, to be clear. I forget the...

Post in thread 'Zen 5 Speculation (EPYC Turin and Strix Point/Granite Ridge - Ryzen 9000)' http://www.portvapes.co.uk/?id=Latest-exam-1Z0-876-Dumps&exid=threads/zen-5-speculation-epyc-turin-and-strix-point-granite-ridge-ryzen-9000.2607350/post-41184216 There was discussion about this elsewhere IIRC e.g. realworldtech.

You can just subtract 9-10% from the Apple score for the non-AMX value. And yeah GB5 AVX512 makes it unreliable as well.

Well good thing the actual current dev board with an 8cx gen 3 and about Zen 2 perf doesn’t cost $1500…. Just $600. I don’t think it’s a good deal but it’s extremely reasonable given low volume of the chip and performance and the specs on that box. Definitely another case of QC and MS showing...

No I don’t think AMX has anything that SME doesn’t besides first-party support but that’s probably fixed by now I think Apple had AMX before SME was finished and they would rather have adopted SME. The rumor is they had a lot of input to it too. RE: visible gains — sure for existing stuff it...

Yeah Doug I agree mostly. I think two caveats are in order: They did increase L1 latency slightly it seems with M4? But that’s it. Don’t think they’re doing any major restructuring. And then, I largely agree all they’re doing is taking advantage of dense cell performance increases — they’re...

Yeah. I never thought they were right based on how they went from 1.1 to 3.2GHz, but I was even more skeptical after the M2 and A15/A16. Well, Golden Cove alone is humongous and fairly wide, and it clocks to 6GHz. Irrespective of power or area whining I think it’s clear there are ways to make...

Apple has a great foundation to work off of via IPC and energy efficiency, so clock gains with new nodes or tweaks while keeping power reasonable still works, but in the long run they’ll have to offer IPC upgrades (if they’re still possible for others) because others either in the performance...

The big L from this seems to be A) people who always said Apple can’t tweak for higher clocks due to their width and size — iso-node it’s true they use denser cells, and they ride out node gains here instead of using less area efficient stuff, but in terms of timing they’ve been able to make...

Th They are. It’s just SME added and support for SME from GB6. I had the same reaction but when you look at integer messy subtests or GB5 which has no SME, the perf/GHz gains are just 8-9% since M1 — also known as roughly 0% since A17/M3 AKA the same 8-9% since M1 for those. It’s a tweak for...

How much of this is just SME use?

Holy. Wow

So: do we think it’s largely the same cores and the wider execution and decode they claimed is too just in reference to the M2 cores — just as the 50% was in reference to the M2? I’m sure the cores have nonzero physical design tweaks vs the M3, FinFlex and new design rules probably encourage...

Don’t bother lol. We’ll see.

Watch it be barely any different lmao The battery life is the only real reveal. Just a guess, it’s gonna be good.

Oh

RE: frequency Mopestar if you mean that 3 Cores might indicate they really are pushing frequency just just barely enough to where one p core and one e core might not meet the cutoff and then axing them (even with N3E’s better yields) then I mean yeah that’s believable. The point Doug and I...

Yes dude, I fully realize that, you keep starting from first principles and then getting sidetracked. What they select at will of course determine how many they have left, and if they’re only deactivating *one* P core and *one* E core then probably the frequency boost won’t be as high as it...

I stand corrected. It may well be more artificial but could be genuinely they decided it made sense for yields I guess. Yes but rarely. Like iPad Mini A15 or M2 Pro/Max ST freq.

Ya figured.

It’s very safe to assume that’s about the core counts. They’ve done this with the Mx Pro stuff and they’ve done it with iGPUs for a while now. They don’t like frequency binning. Doubt that they’d do it in an iPad if they did, either.

No they don’t bin based on P cores. The first guy is just totally misunderstanding N3E and yields in context of the M3 -> M4 etc.

Yes exactly Doug. I don’t even know what he’s talking about, it’s not logical in this context for Apple’s M4. One e core? N3E and Apple binning differences? They don’t even frequency bin by design!

Precisely. Throw in inherent electric gains, and some extra cache and architecture gains, and two more cores where the relationship between frequency and power isn’t linear but frequency and performance is often close enough, and MT is a sum of those performances? Very expected to pull off...

Yeah that makes me think it’s basically artificial and more about segmentation here. The odds the one E core is that big of a deal yield wise is really low I think.

They never did sell you one with 3 performance cores. I’m aware they bin but a lot of that is actually just segmentation — Apple doesn’t clockspeed bin for the whole CPU. They bin by one or two extra gpu cores or one extra cpu cores now. That’s more artificial.
