How much slower are the low power cores vs the high perf? Seems like there would be some interesting scheduling/data dependency for highly threaded workloads if you spread the work across the different cores

Installing Tiger on a non-watercooled G5 right now, I forgot how much of a right pain in the rear end this stuff used to be. I should probably re-paste it too, but I really don't want to deal with removing the ridiculous heatsinks on this thing or re-attaching them to the bare dies underneath.

The performance difference between Intel macs and PPC macs was so vast after two years that dumping the PPC Macs after 2 years was reasonable. In 2 years Intel macs will still be fast and more than capable of handling any new MacOS version for 5 - 10 years to come without issue.

Yeah, but at some point you have to drop "legacy" x86 support in order to force some developers to migrate to Apple Silicon, and Apple has no issue with doing so sooner rather than later. It also eliminates the need to continue to support the x86 code base. Edit: Binary Badger posted:fortowards the end, Apple was selling the 2.7 GHz G5 with a friggin' One KW power supply..

My air was delivered yesterday. Never had a mac pc, what a nice piece of hardware. One weird thing I had the screen went black today and didn't light up when I pressed a few keys (but was making sounds), after I put it to sleep it prompted me for macOS update. Do people tend to use the trackpad for a mouse all the time? I was looking at keyboard shortcuts docs so I try to rely on the keyboard more actively than I would on a windows but anyway the trackpad is surprisingly usable. I hope I won't destroy the device through misuse. Like, is there enough durability to click the trackpad all the time or people just don't do that?

By having the best haptic engine in the business. I've owned both Magic Trackpads, and even when you only press on the corner, it feels like a real button. It isn't until you turn it off that you realize the thing has no movement or give at all.

Really good haptic feedback. If you wanna really weird experience try to click the trackpad when the computer is off after having gotten accustomed to it clicking for a week or two.

They've had it for $100 off I think since it pretty much came out. I think it was just a combination of the holidays and competition doing discounts also, though typically $50 off.

Ok Comboomer posted:Can all cores run at once? Will/do we see apps that treat 4big+4little functionally as a 5 core cpu? Yes all can run at once. No to the latter, because eight cores are eight cores even if half of them are slower than the others. The macOS scheduler manages what runs where. There are APIs which let apps provide hints to the scheduler. For example, say you're writing an email client. You don't need high performance on the thread which periodically checks in on an email server to see if there's new messages, so you mark it as a background low priority thread. The kernel will usually keep it on E (efficiency) cores if you do this. On the other end of the spectrum there's something like "this thread is important because user clicked butan and wants results NOW", which will give that thread priority for P (performance) cores. Apple's E cores are very high performance compared to what typically gets used as a LITTLE core on the Arm Holdings designed side of the fence, by the way. AnandTech's A14 review posted:I’ve included the efficiency cores in the chart here to showcase that they’re not weak at all. The performance showcased here roughly matches a 2.2GHz Cortex-A76 which is essentially 4x faster than the performance of any other mobile SoC today which relies on Cortex-A55 cores, all while using roughly the same amount of system power and having 3x the power efficiency.

Got the Pro M1 8GB 256 today and really like it. Wanted to get the 16GB, but it is not available for another month from anywhere it seems. I really like it, it is so smooth compared to my old i7 xps 13. Hopefully I didnt shoot myself in the foot with the 8gb but the machine will never be used for photo or video rendering or games. Office, R studio, browsing and maybe some other analytics software.

Background: I have the Apple USB Ethernet adapter and a A to C adapter, but I want to free that up. I also have the Apple TB Ethernet adapter and TB2-3 adapter, but I’m trying to use the hub on my USB-C monitor which of course doesn’t support TB. I only have two TB ports on my MacBook so I want to keep the other free for external drives. Bob Morales fucked around with this message at 22:35 on Dec 28, 2020 |

Rob Art benchmarks the M1 MBP against.. a Mac Pro 4,1 tricked out with a 12-core 3.3 GHz Xeon and an AMD RX 5700 XT.. https://barefeats.com/m1-macbook-pro-versus-2010-mac-pro.html To no one's surprise, the M1 MBP beats the Mac Pro in six out of nine benchmarks. Many of the benchmarks were running in Rosetta 2 on the M1 MBP.. (Don't know why he only identiies it as Rosetta, not Rosetta 2..) Of the three benchmarks that the Mac Pro won, two of them were GPU based where an RX 5700 is certainly going to beat the equivalent of an RX 560 (the M1 GPU), and the third was an After Effects render which was likely RAM / CPU dependent. Rob Art of course leaves out the RAM specs for both machines, but I'd be willing to bet the Mac Pro was likely amped up to 32 - 64 GB of RAM. Don't know why he hasn't benched his vaunted 2019 Mac Pro against the M1 yet, unless it's some misplaced vanity where he doesn't want to because he solicited donations from readers of his site to help pay for the Pro..

That's a decade old Mac Pro and the comparisons are on arbitrary benchmarks. The benchmark comparisons for the M1 kinda highlights the poor state of Mac technical reviews.

How does Apple's shipping process work? They pulled the funds out of my account for my M1 16GB Mini but I ordered it days ago and it still shows an arrival date of January 15th. I feel like my past experience with Apple is they only charged your card when shipping was imminent.

You’ll probably get a shipping notification soon and it will show up a couple days after.

Yes, but only with DisplayLink, which is basically a separate GPU that runs in software over USB. It's exactly as slow and bandwidth-starved as that sounds. If you just need to display static office documents, it's fine. Anything with significant motion looks awful.

OK, actually googled it and WTF? That is bullshit. I could get if they needed to drop the internal display for dual external outputs but if the Mini can support dual external displays they should have put a workaround like only powering up the second port with the laptop lid closed if it is a 3 display limit. Pretty sure they make video spanning adaptors still, they used to be more popular with video wall applications although a little pricey, one input gets presented to the video adaptor as a single 3840x1080 or a 3840x2160 display but is actually broken out into 2 or 4 video signals for independent displays. Pretty that feature is actually part of the current Displayport spec that Apple ignores. Three Olives fucked around with this message at 05:18 on Dec 29, 2020 |

Yes the m1 laptops can only run 1 external display, which doesn't make much sense because it can drive a 6k monitor which is actually more pixels than 2x 4k monitors. I think its because the m1 cannot run 2x 6k monitors and apple wanted to avoid the the headline "the new apple laptop can't run 2 apple monitors but will run 2x 4k samsung monitors". I have a feeling they will enable 2 monitors in the future.
