![]() I agree, single thread performance on x86 has been stalled for some time. All they can do is to pump frequency at excessive power like i9-9900 Even unreleased second gen 10nm chip IceLake is only barely faster. They shelve the same microarchitecture all these years. Intel single thread performance is stalled in 2015. Your link puts apple roughly 1.5years behind intel in terms of performance, which isn’t bad at all, but I’m a bit confused by Thom suggesting that it already happened. But it would be too early to make that claim until the latest generation ARM processor is shown to beat the latest generation intel processor. I think if companies like apple throw enough money at the problem, ARM eventually could dethrone intel as the performance king. On performance per watt, ARM has been excelling for a while, but overall performance was still slow. I’ve been eager to get ARM for datacenter applications for years now. Yeah, there’s no doubt ARM chips are making lots of progress. Anecdote isn’t data, and YMMV, but still interesting: Most likely due to the A12’s enormous on-chip cache, which is mostly there to support GPU and imaging functions, but they’re definitely in the ballpark of being “fast enough”. ![]() I read a blog post yesterday in which a CS researcher ran his code (single threaded) on his phone (A12) and found it faster than his i7-7700k workstation. Even the thermally-limited MBP laptops have fans, and the ones that don’t (MacBook etc) clock very slow. The A12X is managing those results at (probably) no more than 2GHz and no fan. So the MBP may hinder intel’s CPU in that it cannot reach it’s peak performance due to throttling. I posted a link of this not too long ago. Macbook pros are handicapped by relatively poor heat dissipation, which results in CPU throttling. Did I miss something? That’s not to say the ipad’s performance isn’t impressive, but how did you arrive at your conclusions? The benchmarks show the ipad beating other devices in the mobile form factor, but from what I see, none of the benchmarks show it beating the latest intel laptops. ![]() It seems like with this exclusive Ars Technica article, Apple is continuing its A12X marketing blitz, which all just further solidifies that Intel’s days inside Apple’s Macs are almost over. It turns out that the iPad Pro’s striking, console-level graphics performance and many of the other headlining features in new Apple devices (like FaceID and various augmented-reality applications) may not be possible any other way.ĭuring Apple’s event last week, the company didn’t even mention Intel once, and profusely made it very clear just how much faster the A12X is compared to all other laptops – even its own – that obviously all run on Intel (or AMD) processors. We wanted to hear exactly what Apple is trying to accomplish by making its own chips and how the A12X is architected. How is this possible? What does this architecture actually look like? Why is Apple doing this, and how did it get here?Īfter the hardware announcements last week, Ars sat down with Anand Shimpi from Hardware Technologies at Apple and Apple’s Senior VP of Marketing Phil Schiller to ask. It’s all done on custom silicon designed within Apple – a different approach than that taken by any mainstream Android or Windows device.īut not every consumer – even the “professional” target consumer of the iPad Pro – really groks the fact this gap is so big. ![]() Apple’s latest iOS devices aren’t perfect, but even the platform’s biggest detractors recognize that the company is leading the market when it comes to mobile CPU and GPU performance – not by a little, but by a lot.
