New Arm CPU is 15% faster than previous generation - Cortex-X4, Cortex-A720, & Cortex-A520

How did you measure all that speed ups?!?

very exciting!

And as every year here is Gary's ARM new Cortex breakdown!

I have to say that I am mildly interested to not all that impressed by the new ARM cores, I have seen a video by Geekerswan a few months ago where they did the power curves via SPEC for many ARM cores and since ARM V9 A7X0 cores have not been amazing in power efficiency terms and I hoped that this time around they managed to slash the power consumption when running the cores at their maximum to bring it down to the A78 levels.
Let's see how manufacturers implement these as I suspect they will be running them at full blast to win benchmarks...

I’ll be mostly disappointed if the new PI5 doesn’t have a maxed out SOC with at least 10 Cortex-X4s. And the GPU obviously.

What's data gathering hint feature ???

On average, how much overall power does the CPU use in a phone? I would have thought that the screen is the main thing, then you still have loads of other hardware suckling from the battery, I have no idea where the CPU fits in here.

So, let's say phone X lasts 24 hours under normal use. Then only the CPU is upgrade and this new CPU is 20% more power efficient. As a rough guess, how much would this generally affect the lifespan of a phone under the same conditions of normal personal usage?

+20% on 24hrs is 4.8hrs but we know it's not going to be close to that, but is it negligible to the overall energy usage of a phone or ~30mins, any other guesses?

I'm excited what the SoC Qualcomm is going to produce based on this new cores design this year🎉 Finally they will get rid of 32 bits and no longer a710 cores inside new generation of chips. And no longer 4 cluster chip architecture, which was basically created to support 32 but apps to the detriment of efficiency.

But still 2mb of l2 cache is not even close to a16 bionic with 16 MB (performance cores)
4 MB (efficient cores)
24 MB (system cache)
Of l2 cache

With a 20% energy saving will they reduce the battery size by 20% to make them lighter, thinner, or smaller?

Apples a17 should remain a good bit ahead still but this looks like a very nice improvement for arm.

So companies can fuck us over with those a 720 cores since it doesnt seem like the worse and better ones are labeled differently. Great

Hopefully Qualcomm can make apple run for its money for once!

I am far more interested to see a single board computer based on the X4 than a phone, or tablet.

I hope Microsoft take windows Arm seriously and developers adapt their programs. I have several actively developed programs that have problems on ARM( auto desk inventor, Schneider electric machine expert)

Apple going to hopefully design am even greater chip for future products

Nice overview

Normal intergenerational development. Nothing special.

ARM is boring.. besides SBCs there's no interesting product carrying these.

More performance is always nice , better battery too , oh and to have had one of these in my galaxy note 4 , 9 years ago :) .

I don't think the 15% increase even reaches apples A15 in single and multicore. Pathetic. Let alone when the A17 comes out

And with the power draw being less, is it independent of the upcoming 3nm chips as this will also drastically reduce power draw 🤔

I wonder if a laptop chip set up with the full 32MB L3 and a 12+0+2 layout would perform. 12 threads of X4 would be rather power hungry, but the performance would be stellar. The 2 little cores stick around for standby tasks and maybe keeping certain OS functions going when the big cores are loaded.

I wonder what would cortex X4 equivalent intel/and processor be when it comes to performance. I know it's different architecture

This means Speed Test G's next update will be dope.

I get so annoyed at the inconsistency of naming things. I see it as “ARM” and “Arm” and “arm.” I’m fine with all caps or all lower-case (as a stylistic choice), but since it’s an acronym, I hate seeing “Arm.” Intel does the same thing referring to their new GPUs as “ARC” and “Arc.” About as annoying as acronyms with too many letters or start using characters in the middles of words just to make a preferred name work. e.g. “TBT” for “throwback Thursday” when it should be “TT.” Sorry, I’m in a mood. :-)

Funny how ARM started really putting effort in their cores and especially the X cores once it learned that Qualcomm bought Nuvia. Otherwise we'd still be 3 generations behind the Apple chips in terms of single threaded performance.

Professor Gary, I don't know if you'll see this comment, I know you don't do Speedtest G anymore, because it had a low audience and it was extremely laborious and costly to carry out the various tests. But here's my request from a fan of yours, when you feel like being able to do them again, but with a much lower intensity, that is, test only one device of each main SoC, that is, the SD Gen 2, A16 and D9200. Regarding the tests, a CPU peak test can be done, but with the introduction of energy consumption analysis and the average performance, with the GPU the same as the CPU. It can also introduce ray-tracing tests and more complex ISP and AI tests to truly test the capabilities of current and future SoCs.

I think X4's 15% performance upllft can't beat Apple's A17 single core performance, Hope Qualcomm is ready with Orion CPU😌

I am curious if Apple is using the different various for their upcoming M3 or M4 processors. A combination with 3nm and their own mix would be killer.

I just replaced my four year old Galaxy note 20 with a Galaxy S23 Ultra. Synthetic benchmarks are twice as fast and all apps feel faster and smoother. you definitely noticed the 3.3 GHz X core. And the battery life is much longer. What a great time to be alive!

so this means by the same area, we've just got 10% more performance after 3 generations.
0. a78
1. a710
2. a715
3. a720

Qualcomm went against ARM in the Nvidia purchase. There has to be a lot of hard feelings about that and in 2024 when Qualcomm starts making their Nuvia chips, as the lawsuit shows. Arm wants Qualcomm to destroy their last 3 years of chip design. Going to get very ugly.

for me its a lot of marketing talk.

it would be interesting how power efficient these cpus really are. how much watt do they use etc.

Hope MTK makes a good designs from these CPUs, Cuz Qualcomm is no longer it used to be

So can we all recognize that ARM went to producing chips themselves. Aka now the subs like Apple, phones, etc. Now buy actual ARM chips. Making dev 100 times easier!!!

Will any of the other ARM licensees come up with a SoC comparable or better than Apple's M2 or A16?
The RISC side of computing is getting really interesting for us consumers. From SBC to tablet/mobile, laptop and desktop space.

I look forward to seeing what Apple does with these new core designs as reference for their M series of chips on their macs and such.

I would also love to see what Qualcomm will be doing and I’m crossing my fingers that something can make it’s way to the laptop space in mind for windows and Linux.

Obviously the phone and tablet space with be the primary use case for consumers but I don’t really feel that much of a difference between generations when it comes to mobile use

Those efficiency numbers are based on...3nm chips. So, we should expect FAR better efficiency than 15%. ARM is dead with those numbers.

More performance per Watt that's how smart design should looks like👍

I think they should reduce A520 cores to just 2 because it isn't meant for multi threaded performance, just for background and light tasks. The most performance range is covered by A720 cores. Its quite flexible as seen from the graph. They should try to include more of these as they have better sustained performance and thermal efficiency. 1+5+3 or 2+4+2 makes the most sense with larger l2 and l3 sizes.

Wish we can get a chip that have a similar performance to Apple M-series chip.

1) A powerful ARM based Windows Laptop
2) A powerful Linux based Laptop or Handheld gaming device
3) Next gen Nintendo Switch with maybe 2TF to 3TF GPU performance
4) Powerful VR headset
5) Ipad level Android-base Tablet.

Aren't apple chips also arm? But why don't they use arm cortex found in mediatek and snapdragon? Anyone can explain?

Cortex a7 came in 2014 with Philips designed NEON technology catering to media, which is text, sound, and imagery. And images for gaming are simple arithmatic for ray-tracing.. But they are no good for number crunching required for general computing. Isn't that so Gary?. Your comments please.

Whenever I watch these videos, I can feel my phone getting slower!

x86_64 ftw!

The 't' in 'often' is silent.

Can someone help me find information about Cortex-X4 pipelines? Thank you for your attention.

Existence of Cache L2 & L3 in one processor are ultimately crucial.
