WW 752: Smushed!

Beep boop - this is a robot. A new show has been posted to TWiT…

What are your thoughts about today’s show? We’d love to hear from you!

A friendly fact check…

— Intel won’t be figuring out M1 power consumption for 3+ years minimum. It’s not even close. Apple has been far more motivating to Intel than Microsoft, Qualcomm, and Samsung combined. Intel has hit massive record sales with 14nm—they don’t care about “the industry”. Should Intel do anything differently, according to their shareholders?

— Apple does care significantly about backwards compatibility in one important way: macOS (arm) is much more backwards compatible than Windows on Arm. Rosetta is much more performant and even runs games decently (!).

— Windows users don’t expect “decades” of backwards compatibility, though. Newer versions of Windows simply don’t run all old apps. That’s one major reason why so many stay on Windows XP, Windows Vista, Windows 7, etc…

— Microsoft’s “thousands” of chip engineers don’t make CPUs, though. They tweak other companies’ CPUs. Chip engineers aren’t the same as CPU architects and SoC teams.

— Virtualized Windows-on-Arm on M1 = a good experience = Qualcomm’s ancient Arm CPUs on Windows are too weak, unfortunately.

— Battery life: Paul doesn’t run battery life tests, though. The Surface Pro X only earned a very meager 469 minutes on the Notebookcheck WiFi 1.3 tests. That’s worse than the average 2021 convertible. :sob: M1 laptop hit ~1,000 minutes on the same test.

— The MBP 14” and 16” are hardly thicker. Did Paul measure that? Should re-check. The reason the M1 Pro / Max need active cooling is because they’re desktop replacements and beat many Intel & AMD desktop chips. They have HDMI ports—very few thin and light laptops have those. Different markets.

— Mediatek will have the fastest Arm laptop chips of 2021 and likely 2022. See the Kompanio series (nee MT8195)—Qualcomm was so slow, even Mediatek leapfrogged them. Not even close: A76 vs A78.

— AMD did try a few Arm chips and the now-canned K12, and so did Intel (“XScale”) from their DEC acquisition of StrongARM.

Besides that :sweat_smile:, eager to listen to the rest of the episode now.

It is also interesting to see side-by-side thermal shots of a MacBook Pro 16 from 2019 with the new MacBook Pro 16 2021 with M1 Pro processor. Sitting on an idling desktop, the Intel MBP has fans running and the whole thing glows bright orange, the M1 MBP is still blue/grey and the fans aren’t running.

There is a difference between needing active cooling and needing active cooling under continued full power. The old Intel MBPs ran fans a lot of the time, the new ones hardly ever under normal desktop conditions - 5K or 8K film rendering? Yes. Using Word and Excel? No.

I agree, Paul was a little disingenuous about the new MBPs being thicker, as you say, those extra ports just won’t fit on the thinner old design, and Mac pro users have been crying out for some of these ports to come back for years now.

I have a Rzyen 1700 desktop, it has active cooling, but the fans rarely spin up to an audible level (it was a bog-standard, relatively cheap, no-name system I bought on Amazon). Even playing GTA5 for a couple of hours didn’t trouble the cooling enough for it to ramp up the fans to an audible level.

Hammering benchmarks through it, and, yes, it becomes audible - usually the only thing you can hear is the physical disk spinning up and down every hour, when Windows syncs the SSD to a backup folder on the disk.
