Arm Cortex-A78 and Cortex-X1 Revealed: Most Powerful Cortex CPUs Ever

No worries we are all human, and I'm not a modern Apple fan, but it does make me wonder if they will use the Cortex-X1 in things like the Macbook Air, and maybe even their entry level iMac computers, the same as many Chrome OS devices have done in their combo of ARM/X86 machines.

Apple doesn't use Arm's Cortex CPU designs, it uses it own CPU designs. The question is will Qualcomm and Microsoft build a laptop processor using the X1 for an upgrade of the Surface Pro X.

I can smell this X program is actually a Qualcomm request. They realize if they keep going at 20% performance increase pace per year, they won't be able to catch up with Apple's cores. Although overall performance Qualcomm often wins, but the gap in very specific single core performance is huge they need to bump higher than the normal YoY increase. Just my 2 cents.

[@fanban2926]

Yeah what if they did this, What if Qualcomm used 3 cortex A78 cores and 1 cortex X1 prime core that's clocked at a higher speed like they've don't with their CPU with normal arm cores? Would be a beast!!

[@patdbean]

Remember unless things have changed since SoftBank. as far as arm's bottom line goes, the same royalty is paid for each core sold regardless of licence type. Apple have an architectural licence , qualcom's build on cortex or Samsung's direct cortex A72 licence . If you manufacture a 64bit V8 core you pay a given number of pence /cents per core shipped.

[@paulbidde719]

I wonder why wont they just use octa core A78/A77 (highperf cores only) and ditch the A55. 2 cores in the ultra freq, 2 in the high freq, and 4 in the medium freq hertz. Put big battery. Put an elaborate cooling system and 6000mAh would suffice

[@CrackDavidson1]

I see it also as a push for proper ARM desktop. Wouldnt mind a Octa-x1...

[@Mainyehc]

Or maybe, as Johannes Näsman said, it'll be useful for ARM desktops? Now that Apple has announced their transition to ARM-based Apple silicon, they will have to replace all Intel processors currently found on the iMac, the iMac Pro, the Mac mini and the Mac Pro… And even the processors found on the top-of-the-line small (13/14-inch) MacBook Pro and on the larger model (which should probably stay at 16'', as it was redesigned so recently) will be closer to desktop-class than those currently found on the iPad Pro models and the DTK, and likely to appear on future MacBook Airs and low-end MacBook Pros, so… yeah, some customization and optimization for performance over raw battery life and thinness is definitely in order.

[@the1barbarian781]

How much power do the x1 cores use? I assume it is only for laptops and hopefully not phones

[@kensmith5694]

I suspect we will see an ARM with tightly coupled GPU. Rendering video is being done on lower powered machines. Once someone starts watching video, the machine could shift to a mode where there there is just enough extra ARM performance to catch a user input etc. The rest of the cores could be depowered or declocked. While the video plays. If a game is being played then perhaps many cores fire up to handle the multiple threads.

Those will all be on 5nm as well. Apple has been a step ahead of everybody in the ARM core design area pretty much since the days of the A8 and A8X, and they have been extending that gap, not the other way around. @Z3U5 - Gary Explains is correct. Apple’s ARM license is an Architectural license. They currently design their SoC’s using their own custom CPU and GPU core designs with the ARM architecture, not using the Cortex core designs at all.

The reason given for that was Qualcomm needed a response to Apple's first to arrive 64 bit ARM chips, and their R&D hadn't brought forth a chip yet.

Not even close, notice that 20% increase is also included the jump from 2.6GHz to 3GHz, Apple gonna jump even higher. Even A77 vs A76 is 20% ipc improvement

[@Roedygr]

I would like to see a giant list sorted by manufacturer and performance of all possible cpus.

[@GaryExplains]

I guess Geekbench is the closest thing to that.

[@dfbess]

I read about these this morning.

[@AchwaqKhalid]

Any info about Spectre/Meltdown bugs 👻 🐛

[@afif4738]

This seems like a very minor upgrade, almost unnoticeable. Is it true?

[@Faraz-cse]

Here A77 (7 nm) @2.6 GHz while A78 (5 nm) is @3.0 GHz show only 20% performance increase.. & I suspect if A77 (5nm) @3.0 GHz can give same performance, so how is tha an Upgrade 🙄

[@GaryExplains]

Only 20%??? Only? Are you 20% cleverer than last year? 20% fitter? 20% healthier? How can you say "only 20%". Also an A77 (5nm) @3.0GHz does not give the same performance as an A78 at 3GHz. Did you even watch the video?

[@Faraz-cse]

@@GaryExplains sorry if I made you angry, I didn't intend to.. Yes I watched complete video & waiting for your next Video on 2 GPU architectures. A77 showed a major upgrade with introduction of L0 cache per cores, but QUALCOMM launched only 1 processor (865) with it. & sticked with A76 & Launched so many 700 series processor (+ 675) based on A76. Though if QUALCOMM launches X1 (prime core + 3x A78 + 4x A55 will be better. & that seems promising 🙂

[@GaryExplains]

I don't see how Qualcomm is related to this. If Qualcomm has a product roadmap with cost/performance targets, I don't see how that adds to or detracts from the Cortex-A77.

[@dominozonda]

@@GaryExplains he's right, it's not that great of a jump, and most of it due to the new 5nm manufacturing process

[@aymanali4668]

Does Apple also build its CPU based on the ARM cortex-A series?

[@Ali-te6lw]

No

[@priyaarun2837]

No

[@GaryExplains]

No.

[@JohnWick-xc4lm]

will exynos 992 have A-78?

[@sbrader97]

Probably not too soon I think it won't be until the s21 exynos 1000. In b4 the 992 is just power saving on new node like the 9825 vs 9820 was not much performance boost, if the 992 is even real.

[@scenicdepictionsofchicagolife]

I'm wondering if maybe Google will be using this as an opportunity to beef up it's custom Silicon ambitions and if so how that will pan out for Pixel and Google devices.

[@galdutro]

Gary, do you think we will see more companies developing ARM SoC´s for the Windows ecosystem?

[@GaryExplains]

Not at the moment, no. Windows on Arm is very much a Qualcomm + Microsoft thing. If it succeeds then sure, others will want to join the party.

[@samvortex4136]

What we need is A58

[@SouravTechLabs]

11:37 8 GB L3 Cache, You probably read the script wrong 😬😬

[@rivox1009]

they said, fuck it, remove the RAM, make the chip one square mile of pure raw silicon juice and use the L3 cache as memory

[@GaryExplains]

I don't use a script and I guess you didn't read the pinned comment.

You think he needs a script dumbo ?

[@Albaloola]

Is this arm cpu you talk about is faster and more efficient than x86

[@GaryExplains]

Faster than which x86 CPU? There are literally thousands.

[@Albaloola]

@@GaryExplains is it faster than core i 9900k

[@GaryExplains]

The i9-9900K has a Thermal Design Power (TDP) of 95W and runs from the main electricity with huge fans and cooling. The Cortex-A78 and X1 run from a battery in a smartphone with no cooling and a TDP of 5W. They are completely different things, of course the Cortex cores aren't faster, but they are way more efficient.

[@nimrodlevy]

are there any mobiles today that does not use arm at all? (except the failed intel atom effort about 5-6 years ago) - back in the days mobile devices namely handheld consoles used to use 68000 (if this arc is sill alive) and zilog and mos and stuff like that, is it even possible and/or feasible to have non arm mobile phone these days ?

I was going to say naaah, because Android does not support x86. But I was wrong, and there is even a phone! A chinese phone called Leagoo TC5 of december 2017 uses a Spreadtrum SC9853I processor which is an Octa-Core 1.8GHz Intel Airmont. It's true! Google it! www.kimovil.com/en/where-to-buy-leagoo-t5c

[@GaryExplains]

Android has and still does support x86.

[@mem.info0]

So all we have now is to survive till the end of 2020

[@Simoss13]

Surprised noone has asked this, is the A78 coming to Tegra Orin and hopefully in Nintendo Switch 2.0?

[@GaryExplains]

It was asked.

@@GaryExplains I probably didn't realize. It's 4am where I am and just glad to read about ARM Cortex while trying sleep

"allow" is not a word in tech. They will make profit from reducing cache, no doubt about that

[@md.monzurmorshedshohugh3080]

SQ1 vs x1 which cpu is more powerful

[@GaryExplains]

SQ1 is a processor, X1 is a CPU core. But since the SQ1 uses the Cortex-A77 then the answer is X1.

[@md.monzurmorshedshohugh3080]

@@GaryExplains I saw some pc gaming videos of surface pro x and the performance was very good Just think about it if Microsoft release a smartphone with x1 core and full windows support that will be a game changer
