You’re making a bit assumption that may or may not be true: that M1 will scale well to 8 performance cores. x86 vendors (and POWER) and Linux have put a lot of effort into multi core scaling in the last 15 years or so. Building a fast and efficient core is not the same thing as building one that scales well. I’m sure that Apple is capable of making an effective 8- or 16-core machine, but it may not be as simple as ju…

Core and cache organization gets more difficult, yes. So do thermals and layout, which is not where Apple has experience (they don’t make any custom chip that requires a fan that I know of). That said, they have had a looong time to think out this, so I have confidence they will make it work over the next two years.

However, the sentiment that the M1 chip obliterates any and every desktop part on the market is getting kind of silly at this point. 1. Nobody ever stated that. If anything, it was all of the Intel and AMD users who created that straw man. "See, it's slower than a 64-core Threadripper at 280 watts". No kidding. 2. The M1 is clearly not a desktop-class SoC nor was it intended to be. However, it's more than competitive…

Doesn't include monitor, keyboard, mouse, speakers, webcam, microphone, battery backup, and fingerprint scanner which would be necessary to make it "comparable" to a base model Macbook Air. It also isn't a portable, fanless laptop which has its perks.

There are plenty of 8 core/16 thread Ryzen 4750U laptops for around the same price that outclass the M1 in multicore benchmarks.

The reason people are making these comparisons between CPUs that are basically in entirely separate market segments is because of apples marketing suggesting that the M1 beats everything , rather than just other low power CPUs, and people taking said marketing at face value.

>apples marketing suggesting that the M1 beats everything Nope—Apple’s marketing never said that. Everything they said in their November 10, 2020 press release has been backed up by reviewers and testers. It's you guys that blew their claims out of proportion. For example, there's no reason to disbelieve that the M1 13-inch MacBook Pro is up to 3x faster than the best-selling laptops (of the 9 months leading up to No…

In the real world, there aren't many people making purchasing decision between an M1 Apple laptop or Mac Mini and an AMD 5800X desktop machine anyway. Still interesting to see the comparisons. The leaked Geekbench results of AMD's upcoming 5800H laptop parts are about 85% of the M1's single core score and matching the M1's multi-core score. TDP is still higher than the M1, obviously, but AMD is also using a 7nm proce…

> In the real world, there aren't many people making purchasing decision between an M1 Apple laptop or Mac Mini and an AMD 5800X desktop machine anyway I have a 15 inch 2018 i9 MBP that's objectively a terrible device (throttling/keyboard). With corona and WFH I'm weighing my options - right now everything is out of stock but early next year I'd be interested in building a desktop. My problem is the M1 is so good tha…
