What's with the 36 GB option? The other memory configs (16 GB, 64 GB) are still clean powers of two. Size suggests that they're using ECC-capable memory but using the extra width intended to support ECC for data... but why would this only apply to a single size? Part availability? EDIT: Digging this a bit, it's not (one or more) 72-bit wide busses with 2^32 words as I'd expect as a gray-beard, it's (probably) six 32-…

64 GB chips that failed testing? That's one way to increase yield. Clive Sinclair did that trick back in the 80s.

Intel and AMD do that now with processors.

It also appears they've dropped the memory bandwidth from 200GB/s on the M1/M2 Pro to 150MB/s on the M3 Pro, and you have to upgrade to the tippy top M3 Max chip to get the full 400MB/s bandwidth experienced on the M1/M2 Max chips.

Interesting that the Myst remake is being used specifically as an example, with how the original was created on Macs using HyperCard.

Yeah, I thought that was a little poetic :)

Especially since (and this just occurred to me), in a roundabout way the original may have been the first Mac game to ever use raytracing (in its pre-rendering)

How did Apple become so successful making high-end CPU chips on their own so quickly?

I don't think we're comparing apples to apples here (excuse the pun). These chips have something like 10% of the instructions that a typical x86 chip does. Once the big CPU players start producing the same kind of chips, I greatly expect Apple's power to performance advantage to drop significantly, if not be overtaken by the likes of AMD, etc.

They've been designing the A-series chips in iPhone and iPad since the A4 in 2010.

A4 was still using ARM cores from Samsung. A6 was the first SoC with Apple cores.

One thing that left me a bit confused was the comparison against Intel Macs. Although I am still using an Intel 16-inch MacBook, I really wanted to see how the M3 fared against the M2, not Intel and M1. I think it's no surprise the M3 exceeds the Intel Core i7-9750H in basically all of Apple's own benchmarking. My real question, which will probably be answered next week, is how it compares to the generation right bef…

Not just that, but if you're not running ARM images then it's running a VM for your docker images to boot. It's just mind-blowing how many containers I have running and my laptop is cool to the touch, and at full battery.

Earlier quoted context omitted.

Calling it evil is a bit of a stretch.

Is it? Its pretty evil to overcharge and prey on a customer base who doesn't know any better, but would benefit from a more usable starting point, oh say 16... Tims a finance guy, they are kinda evil by default.

It's a matter of perspective of course. I think if you claim that this makes Apple evil then you would also need to argue that most of capitalism is evil. Aren't the vast majority corporations just trying to make more money? I would disagree with that.
