Quote from: Digitalguy on December 21, 2020, 12:40:07What sort of nonsense is that? TB3 is still Thunderbolt. Thunderbolt gives you external PCIe. Which means you can use PCIe devices like NVMe SSD. By fully I mean it actually supports the protocol and PCIe devices work (again, the problem with GPUs will be driver related - Apple might be simply interested in cutting AMD off and not give them any space on the new platform). USB4 doesn't. USB4 doesn't include Thunderbolt. They just use some of the technology of TB because Intel gave it to them. You could say they use its physical layer (signaling) but AFAIK even that has been modified and is different to what TB3 uses (it might actually be closer to what TB4 uses but I would have to check). They use this technology to achieve higher speeds. But it's still USB. USB3 can work with TB3 just as well as USB4. Does it even have to be said? There is a truckload of laptops that support TB3 and USB3 on the same port. It just has to be USB-C.
YOU are mistaken. If Apple fully supported TB they would use TB4. Instead they use USB 4, which fully supports TB3. Sure they have TB controllers because USB 4 does support them. You are just reading Apple PR material. TB4 is Intel only. UBS4 supports TB3 for free. Fortunately differences are mainly only different minimum requirements so not a big deal. Apple is not longer paying any TB licence to Intel and the fact that they started TB together no longer matters, since they are stoppiing using Intel anyway

Quote from: Digitalguy on December 19, 2020, 13:33:16You are mistaken. Unlike AMD, Apple fully supports Thunderbolt and M1 has a Thunderbolt controller (two, actually, I believe). Thunderbolt was a joint effort between Intel and Apple IIRC. The situation around eGPUs is probably driver related.
Buy the way the M1 uses USB4 which while not technical thunderbold, it included Thunderbolt 3 specification and is therefore compatible.
Quote from: kninez on December 19, 2020, 04:46:43No, M1 is passively cooled only in the MBA. MBP13 and mini are actively cooled. Yes, a passively cooled device exists. But not all of them are. So, you need to be mindful. And of course, MBA will probably be able to sustain a higher power limit than an iPad.
2) The M1 is passively cooled as well, like on the Macbook Air, no fans whatsoever. It's a laptop verison of the A14X coming soon on the next Ipad pros.
3) The M1 is not running windows natively, it's actually emulating windows (x86) in real time inside the ARM Big Sur OS......and it is still twice as fast.....and that's just the CPU...The GPU smokes any SQ graphics chip Microsoft/Qualcomm releases in the next 5+ years.

I would have been surprised if the M1 didn't outperform the SQ1/2. It's an apples and oranges comparison. The SQ2 is a tablet processor rated at 7 watts and is passively cooled. The M1 in a MacBook is a 15-20W part and air cooled. If the iPad ran windows twice as fast as the SQ1 we would have a relevant story.
