I did not expect ARM would take so long to catch up with even the Apple M1 or the same core designs in the Apple A14. The Cortex X3 in the current flagship chip Snapdragon 8 Gen 2 still _just_ fails to match the Apple A14 (let alone the A15 and A16), perhaps this little design boost is finally enough to match it.

If Microsoft can get Qualcomm to implement some of the same chip tricks Apple pulled off for x86 emulation performance they can use it for a potentially somewhat compelling laptop package. It's a tough ask though, as Qualcomm seems mostly to just use pretty vanilla ARM designs. And I don't expect anyone but Microsoft to be interested in taking that plunge.

    > I did not expect ARM would take so long to catch up with even the Apple M1 or the same core designs in the Apple A14.

    As mentioned in the article, you might want to pay attention to the traditional difference between what ARM promises and what it delivers.

    > these launch events have a history of making performance claims that don't align with what actually arrives in consumers' hands

    • dagmx 3 years ago

      Part of that though is that Qualcomm etc tend to skimp versus the recommended cache values.

      • als0 3 years ago

        This. Vendors skimp on cache size because of overall cost. But cache size is just as critical as CPU core when it comes to performance. Apple doesn't sell chips to anyone else, so they have no pressure to have small caches.

        • GeekyBear 3 years ago

          Which chip that shipped to customers had performance that did align with ARM's projections?

          • als0 3 years ago

            None, because of bad cache sizes and horrendous software

            • GeekyBear 3 years ago

              None, from any vendor who licenses stock ARM cores?

              • dagmx 3 years ago

                They only license the cores, but they pair them with lower cache sizes.

                So you can’t actually find any chips that match ARMs own benchmarks because nobody makes ones at the recommended spec for it.

    • DCKing 3 years ago

      Sure, but it's worth noting that the Cortex X3 in the Snapdragon 8 Gen 2 is _almost_ at the level of the A14 in single core performance, just not quite there. Even if the performance bump is less than promised, they will still equal it.

      • GeekyBear 3 years ago

        It's also worth comparing process nodes.

        The Snapdragon 8 Gen 2 is on TSMC 4nm compared to the A14 on TSMC 5nm.

        Also, the Cortex X4 spec projections are based on the second gen TSMC 3nm process node that isn't in volume production yet. If the M3 is announced (as rumored) next week at WWDC on the first gen TSMC 3nm, we'll have some basis for comparison (at least as far as projected specs go).

  • f6v 3 years ago

    It’s a shame, Intel Surface Pro has underwhelming battery life. And ARM version really lacks in performance.

  • smoldesu 3 years ago

    None of the manufacturers want in. x86 is unencumbered by licensing issues, and RISC-V is moving through evaluation like a jackrabbit on speed. Apple has incentive to make ARM chips - they're deep in bed with Softbank (ARM licenseholders) and were already designing their own ARM cores. Nvidia has a few industrial-application HPC ARM chips they manufacture, but have been noticeably quiet about ARM after the failed acquisition attempt. Intel is cashing in on fabless manufacturing and also not designing their own cores. AMD has it's headphones on and doesn't see the RISC truck barrelling down Main Street.

    So... I would honestly be surprised if anyone tried, at this point. Most of the potential stakeholders don't seem super interested.

To quickly lower expectations before reading the article:

> Every year with these Arm flagship chip announcements, the company also includes a wild design for a giant mega-chip that usually never gets built.

That being said, this 14-core figure is when doing a full-Arm SoC (with Arm internal bus). SoC vendors are still allowed (AFAIK [0]) to do their custom interconnect that goes higher than that

[0] there have been rumors seen here that Arm is pushing towards a model where SoC vendors must do all-Arm components. That still sounds weird to me, and I'm not witnessing any actual effect of this, so I still highly doubt it.

  • als0 3 years ago

    > there have been rumors seen here that Arm is pushing towards a model where SoC vendors must do all-Arm components

    Smells like FUD spread by Qualcomm, who are currently in a legal battle with ARM.

    • dagmx 3 years ago

      Yep, Mediatek for example just announced an ARM processor with NVidia components and there’s already arm processors with AMD GPUs.

      No other manufacturer seems to be beholden to the terms that Qualcomm is claiming.

      I’m very inclined to say QC are trying to push for sympathy in the tech sphere.

      • ksec 3 years ago

        >I’m very inclined to say QC are trying to push for sympathy in the tech sphere.

        And it works every well if you were to judge it by comments on Twitter, HN and Reddit.

        • dagmx 3 years ago

          I think it’s a testament to how people like Drama more than they like nuance.

          Technical people are just as prone to it as anyone else.

  • polpo 3 years ago

    Given that there is a whole publicly traded company that does ARM SoC interconnect as their bread and butter (Arteris IP) and they and their stock price seem to be doing OK is an indication that it’s still allowed.

spaniard89277 3 years ago

Still waiting for non handicapped (thinkpad x13s) ARM competitors. I would like to get performance + long battery + good screen + Linux but it seems to me that It will take so much time that I'm better off waiting for Asahi Linux to get mature and buy a second hand M1.

It's sad.

  • brucethemoose2 3 years ago

    AMD and Intel are coming out with M2-Pro like quad channel APUs. Clock them low enough, and that will trounce anything we have from ARM outside Apple.

drewg123 3 years ago

For anybody looking for a "decoder ring" of sorts that briefly describes arm CPU lines, see https://www.arm.com/products/silicon-ip-cpu/

Finding this was helpful to me, as I can never keep track what is a fast (eg, Xeon equiv) type arm chip, and what's a low power embedded (Atom equiv) and what's a laptop / desktop chip.

It’s hilarious how Apple has become the number one chip maker in the world. Intel CEO Pat Gelsinger called them a lifestyle company…

  • Aromasin 3 years ago

    It's a bit of an unfair statement but I do see where he's coming from. Apple make consumer phones and laptops, professional workstations, wearables, headphones, and TV/Home products. We've yet to see an M series chip for products in any of the following fields:

    Cloud Computing, Computer Vision, Data Center Solutions, Edge Computing, High Performance Computing, IT Infrastructure, Network Connectivity, Robotics, Security, Broadcasting, Energy & Utilities, Financial Services, Government & Public Sector, Health & Life Sciences, Hospitality & Restaurants, Industrial, Manufacturing, Retail, Smart Cities, Transportation.

    Intel, NVIDIA, AMD, Qualcomm, and Arm make devices or design IP for every single one of those sectors. Apples' portfolio is streamlined to just "lifestyle sectors"; stuff people directly interact with in their every day lives. How can you call them the number one chip maker when they don't compete in any of those markets, and even in the one they do they're only superior in performance per watt; not sheer performance benchmarks? Until we start seeing M2 chips in everything from server racks and satellites, I'm inclined to side with Gelsinger on this one.

    • giantrobot 3 years ago

      > How can you call them the number one chip maker when they don't compete in any of those markets,

      Because they produce north of 300 million SoCs every year. They may not end up the number one chipmaker every single year but they're in the top ten and depending on other companies' demand vs Apple's demand may end up number one.

      • Aromasin 3 years ago

        If we're talking about manufacturing volume as the sole definition for "number one chip maker", then the idea that Apple might be first is frankly laughable. If we discounted pure foundries (TSMC, UMC, Global Foundries) they'd struggle to scrape top 5 at the best of times. Intel, Samsung, Qualcomm, Nvidia, AMD and the like work in the range of billions, or near enough. Currently Intel has 76.7% of the laptop chip market share alone; that's before you start considering their server, edge, and network markets. If we start including trailing edge chips, from the likes of Texas Instruments, Micron, Broadcom, etcetera, then Apple would be a small drop in the pond. Even if Apple ate up the entire consumer market, they'd still struggle to compete with the rest of the industry on volume.

        I don't think people appreciate the obscene number of leading edge chips that go into the industrial sectors. I've seen more chips go into a single Industry 4.0 factory than I have to an entire states Micro Center inventory.

  • m0shen 3 years ago

    Number one in performance / watt? maybe? sales? Well no. According to the web[1] total chip sales in 2022 excluding arm amount to 374 million units. Server chips being 36.1 million units. Apple's biggest quarter in 2022 was 7 million macs in Q4[2].

    • argsnd 3 years ago

      Why are you excluding iOS devices?

      • vlovich123 3 years ago

        For anyone curious, iPhones ship 234 million a year, Watch around 60 million, iPad another 20 million. Not sure about Apple TV but let's assume that's 0. That's over 300 million CPUs a year.

        I doubt the total chip number for the industry though - Intel alone ships ~100M. But it's clear Apple is very likely the largest manufacturer of CPUs.

        * Correction: MediaTek shipped 350M units in 2020 and Qualcomm shipped 319M (due to the Trump embargo on China). So Apple is up there competing with manufacturers that sell their chips to anyone who will buy, but it may not necessarily be the largest.

        • hardware2win 3 years ago

          >But it's clear Apple is very likely the largest manufacturer of CPUs.

          Manufacturer? Where are Apple's fabs located at?

          • awestroke 3 years ago

            Not TSMC, that's for sure. TSMC is using ASML machines to etch the transistors, so by your logic ASML is the biggest CPU manufacturer

            • hardware2win 3 years ago

              >so by your logic ASML is the biggest CPU manufacturer

              No? How?

              The logic is pretty simple

              Chip designers are fabless companies: AMD, Apple, etc.

              Chip makers are companies that physically manufacture those CPUs, so TSMC, Intel, etc.

              There is edge case if chip maker has some designs that are created in another company's fabs, but is it relevant for this discussion? I dont think.

        • scns 3 years ago

          Correcting yourself, two thumbs up. Margins per CPU shipped? My first, thought was APL at least 7x MTK but i must be so far off here.

          • vlovich123 3 years ago

            Yeah. How you count things is very subjective to where you draw the line. As for margins it's hard to say because Apple doesn't sell chips independently so their profit margin on a chip is withdrawn from however they want to distribute the profit margins for the entire product and Apple does not provide a breakout a sufficient level of granularity into the financials to understand that.

          • m0shen 3 years ago

            Yeah margin per processor shipped is a different question, and Apple probably does very well here.

  • smoldesu 3 years ago

    It's not surprising, anyone who sells iPhones is going to need a lot of chips. Gelsinger wasn't half wrong anyways - outside the consumer hardware market Apple is a no-show.

    • f6v 3 years ago

      > outside the consumer hardware market Apple is a no-show.

      I don’t have the data, but tech companies are often full of Macs. Sometimes I also see small businesses running iMacs.

      • wpm 3 years ago

        My company is a couple thousand large and we have maybe 50 PCs in the whole org.

      • smoldesu 3 years ago

        Indeed, to an almost comical extent. I worked at a Mac-only shop that spent 50+ engineering hours per-month debugging the Darwin runtime. Our product didn't ship to Mac either, so we were basically fanagling a Win32 + Linux server toolchain to work on a platform we didn't support.

        Tech companies count as consumers, and many consume the Apple product even if it's to their detriment.

      • pjmlp 3 years ago

        Not so much outside a couple of G20 like countries, Windows and GNU/Linux win out.

        Then there are all the electronic devices that have CPUs on them and don't run any kind of Apple related software.

    • oefrha 3 years ago

      Sure, outside Intel’s market Intel is a no-show as well.

    • dankle 3 years ago

      Yes, but in consumer hardware, their silicon outperforms the competition.

      • smoldesu 3 years ago

        Yep. Ray-ban's optics are world-class as well, but that doesn't exclude them from being called a lifestyle company.

        • brookst 3 years ago

          Zeiss would have been a better comparison.

        • qwytw 3 years ago

          Iphone and Macs are obviously huge in the enterprise market though.

          • smoldesu 3 years ago

            If I had a dime for every lifestyle product that was "obviously huge in the enterprise" I could fund the next WeWork in a cash deposit.

              > By 2021, this migration had become a trend. IDC claimed macOS device use across US enterprises reached 23% while iPhones accounted for 49% of business smartphones and iPads accounted for most tablets used in the workplace.

              • smoldesu 3 years ago

                Having enterprise customers and being a lifestyle product is not mutually exclusive, especially in American business.

                • qwytw 3 years ago

                  And? Companies can target multiple markets simultaneously? I mean basically every other phone or PC manufacturer has tried to become a lifestyle product Apple has just been way more successful at it...

                  > especially in American business.

                  Well more American business can afford spending an extra $1000-2000 on superior hardware* for their employees without thinking about it that much. What's wrong with that?

                  *comparable laptops for Dell, Lenovo, HP etc. cost not that much less for Macs. What's the difference between a Dell XPS and a Macbook in that regard? Or Dell is also a lifestyle brand?

                • brookst 3 years ago

                  You're obsessed with this "lifestyle" designation. Ok, fine. Apple's a lifestyle company, whatever that means.

                  • smoldesu 3 years ago

                    Apple is obsessed with their lifestyle designation: https://www.youtube.com/watch?v=zfR_Jj4grZE

                    They publish ads and write all their copy with the intention of framing their products as anything other than a computer.

                    • brookst 3 years ago

                      This seems to offend you for some reason.

                      Apple's just doing age-old value selling, where you promote the benefits of a product rather than the features. See https://blog.hubspot.com/sales/value-based-selling

                        It might shock you to learn that I don't really care :)

                        I doubt Pat Gelsinger does either, since he's publicly stated that Intel would fab Apple Silicon chips at their ARM foundry if/when TSMC goes offline. The guy's just having a laugh by putting an awfully accurate label on a fruit that pays extra to resist labeling.

                        • qwytw 3 years ago

                          > I doubt Pat Gelsinger does either

                          Maybe he should start caring* otherwise he risk running Intel completely into the ground? After all Apple was one of their largest clients until recently. Then a "lifestyle company" managed to somehow design better CPUs than Intel despite that just being an afterthought for them (since apparently Apple only focuses on the "lifestyle" stuff..).

                          I find it so fascinating the people get really obsessed by Apple (both in a negative and a positive way).

                          > I don't really care :)

                          Well a string of your comments would imply that you could actually care less about Apple.

                          *(I'm pretty sure he does in non imaginary reality )

                          • smoldesu 3 years ago

                            Apple should be able to design better CPUs than Intel. They've poached their chip designers for over a decade, and have been the world's largest company for years. Beating Intel's single-core IPC is so easy that AMD did it with Ryzen for a laugh - if Apple couldn't do it on RISC, they may as well have given up making chips entirely.

                            I own no stock in Intel or Apple. It's worth discussing to me because it exposes how insecure people are about relying on "lifestyle" companies. Even Intel is a lifestyle company for some people, and those users are equally as pathetic as the people who let Apple, AMD or Nvidia define who they are. If Apple didn't go to such extreme lengths to appear different and look accountable, their staunchest defenders wouldn't have so far to fall.

            • qwytw 3 years ago

              I don't know maybe you would maybe you wouldn't.

              All I know that huge numbers of employees of both large and small companies regularly use company provided Macs and Iphones for work. Are you actually disputing that? Really?

    • r00fus 3 years ago

      There are entire divisions of major companies that only run Mac M-series laptops.

      It’s no longer the 2000s where group policy is difficult for Macs.

    • stephen_g 3 years ago

      Hardly! In digital media, video, graphics, etc. you're usually much more likely to see Macs than other computers.

  • hardware2win 3 years ago

    By what definition Apple is chip maker, let alone #1?

    • dijit 3 years ago

      If AMD is a chip maker then so is Apple by the same metrics.

      So, pick those metrics, they're certainly pushing large volumes, they're pushing some of the highest performance and some of the most efficient CPUs available.

      So, they're #1 in power efficiency, #1 in fanless performance, #1 in Tablets, #1 in Fanless computers, #1 in Mini computers.

      • hardware2win 3 years ago

        If you outsource chip creation, then you are chip designer, arent you?

        >Fabless manufacturing is the design and sale of hardware devices and semiconductor chips while outsourcing their fabrication (or fab) to a specialized manufacturer called a semiconductor foundry. These foundries are typically, but not exclusively, located in the United States, China, and Taiwan

        What about other categories

        Gaming, Data Center?

        • qwytw 3 years ago

          So if we're talking about high-end chips Intel and Samsung are both designers and manufactuerers? And Samsung seems to have mostly abandoned Exynos and is using Qualcomms SoC now. So that only leaves Intel..

      • sliken 3 years ago

        That's like calling Tesla a battery maker. You can't buy a bare battery from Tesla or a CPU from Apple.

Sigh. Both are factually wrong.

First point, Where the heck did that 63 percent came from? The iPhone 14 is about 38% faster. With much larger die size, and larger cache.

Second point implies ARM is lying. When ARM is the only company that gives precise reading of their benchmarks and ISO performance. How about asking that from any other manufacturers.

My guess is that for hardware you should ignore Ars and only read Anandtech or other site who goes into deep dive. Ars is fast becoming Engadget or just another blog.

  • dagmx 3 years ago

    I really wish Ars would let Ron Amadeo go, or PiP him. Their other writers are much better.

    He’s woefully technically inept, his articles often have unchecked errors like this and he jumps to bombastic conclusions like the whole Samsung ROM size issue.

    Almost certainly, when I see complaints about writing on Ars, it’s a Ron piece.

    • arp242 3 years ago

      But who will obsess over bezel sizes?! I need to know about the bezel sizes from Ron!

      At this point it would almost be a good idea to bring Peter Bright back to replace him. Almost...
