Unified memory too. It's your GPU and your ram.

This is huge for AI / ML at least for inference. Apple chips are among the most efficient out there for that sort of thing, the only downside is the lack of cuda

I consider that a plus. Maybe the AI community wil start to wake up and realize that going all in on cuda is ridiculously stupid.

I wish they would add small UPS inside (like super-capacitor or something like that) there to provide way for forced sleep when power is cut off. It's a neat small device which must be accompanied by huge bulky UPS for reliable operation.

If someone didn't know, macOS ignores fsync, so without UPS your data is not safe. Not an issue for laptops, obviously, but issue for battery-less devices.

The Apple employees who worked on this product cause a lot of CO2 emissions just living their lives. I'm guessing Apple didn't try to offset that CO2.

If we truly want to achieve zero emissions globally we need to take seriously all sources of CO2 emissions, the full carbon footprint of companies. Not just energy use. It's not entirely unreasonable to ask companies to be responsible for carbon capture or in the short term an offset for their employees breathing on the clock, as funny as that sounds. We need to take all sources of carbon emissions seriously. This sh…

Unless you think their employees breathe more when they are on the clock than off it, I'm not sure this makes sense. When they're off the clock, they might be exercising or playing with their kids, so perhaps they actually breathe less when sitting at their desks on the clock.

It would appear the air intake is on the bottom like the Mac Studio. As someone who lives in a very dusty 150 year old house, My Mac Studio does not appreciate the air input being directly on the desk. It collects all the dust that lands anywhere near it. I have a large levoit air filter running 24/7 in my office and still end up with this[1] regularly. I wish I could at least reasonably take the thing apart to clean…

Three points: - Running an Air Filter 24/7 has huge diminishing returns (i.e. waste of electricity). They are best run at max fan speed for short durations instead. - Elevate it with a platform. - Get a vacuum (or even a robo vacuum). I grew up in a 100+ year old house, it wasn't dusty, and had hard-woods/brick everywhere.

I did this experiment in two locations. If I’m in the more urban area, running the air filter 24/7 was necessary.

As usual, no upgradability. There's evidence that it's possible with SSDs with no loss of performance. Probably the same would apply to memory, maybe with replaceable memory chips and a simple switch. More future landfill material.

It does not apply to memory. It’s much harder to maintain signal integrity. 200+ 4GHz signals.

LPCAMM2 solves this.

Apple really is the kind of cherry picking comparisons. They seem to compare the new Mini with the M1 Mini, the Core i7 Mini, and the M2 Mini, all in different categories, whenever it benefits them.

If a CPU is socket-able, so should memory chips be.

Apple puts the memory, CPU, and GPU all on the same chip. This generates less waste as you only need a single package and socket, and uses less energy during operation.

Can you think of any examples where a company trying to sell you something made unfavorable comparisons between their product and a competing product?

I have lots of USB-A devices, so I get what you're saying. But converters are pretty cheap and seem reliable. And Apple has a long history of making this change ahead of the rest of the market. It's been years since they've move to all USB-C in their laptops, so IMO, it was only a matter of time. And yeah - upgrades are awful price wise. From what I can tell, it's basically only worth it to buy base models unless the…

I actually recently discovered that my USB DAC was skipping a lot because I had it connected to a hub. Threw it directly onto the Mac Studio and now everything's peachy, so there are definitely downsides to trying to get a bunch of USB-A devices attached to one of these.

Sadly it's been common for USB hubs to be dodgy ever since the advent of USB 3. I rarely had trouble out of 1.x and 2.x hubs, but 3.x+ hubs are consistently trouble. The only ones that haven't been problematic are those integrated into Thunderbolt docks, probably because those undergo more stringent certifications.
