I’m an Intel strangler because it’s the only way I can have Mac and Windows on the same machine. Am I the only person that really needs this? Parallels has trash performance.

You can run ARM Windows under Parallels, which is good enough for me.

Just throwing this out there: ARM Windows uses Microsoft's own ARM to x86 translation layer (like their Rosetta), which works surprisingly well for run-of-the-mill business apps and the like. 3D apps do take a big hit though.

I think the M series laptops were the first full manifestation of the laptop idea. Instant sleep/resume, great input devices and monitor, cpu power at will without overheating or loud fan, super fast shock resistant storage, 20+ hours of battery life, no battery drain when off. It took us 30 years but we finally have it. Now let’s hope WIntel can also catch up soon.

It's kind of surprising that Intel (or I guess x86 in general) still has basic issues with sleep, laptops waking up in your bag and that kind of thing. The forced modern standby thing they're doing has only made it worse.

The single external display driver can drive more than one display at resolutions at 4k or lower. You can daisychain two 4k monitors on a Mac that has only one external display driver when you use the Displaylink adapter (it’s a driver). It somehow internally reuses the same display output for both displays. The USB-C can power one 6k or 2 4k monitors. The HDMI port on M2 Pro and newer can power one 8k.

Thunderbolt docks too — with a single cable they can drive two 4k displays plus provide power to the laptop.

They really can't on plain (not Pro/Max) M1/M2/M3 chips. No matter what, these machines will only support one external display unless you go the (IMO kludgy) DisplayLink route. It's a hardware limitation and no matter what Thunderbolt dock you have it will not do it.

I have a ~7 year old 27" iMac. It wasn't that expensive at the time and the screen is still way better than a lot of what is on the market today. Now, it is only available in a 24" version. Is time moving backward?

I guess the high-end iMacs and iMac Pros (remember the iMac Pro? 10 core Xeons upgradable to 512 GB of RAM!) just never sold very well, so they canned the idea of selling iMacs to pro users and instead chose to focus on the lower-end market that was previously served by the 21.5".

So it seems to me like the iMac has very much been repositioned as a stylish, basic desktop computer for the home and general office tasks now. No M3 Pro/Max, no bigger monitors, limited I/O, etc. I personally don't really like it because I have labs full of decked-out 27" iMacs that are now kind of left without a clear upgrade path, but I understand what they're doing.

Wild guess but if the base chip has 3 channels and the higher binned chip has 4 channels: 3x6GB = 18GB 3x12GB = 36GB 3x32GB = 96GB 4x12GB = 48GB 4x16GB = 64GB 4x32GB = 128GB

But the bandwidth goes like, 100 GB/s, 150 GB/s, 300 GB/s, 400 GB/s. Given either CPU or GPU alone can't saturate bandwidth (assuming M3 the same as M1 and M2), perhaps the memory controller or the chip layout is to blame.

Right, the two M3 Max SKUs being discussed above are the ones with 300GB/s and 400GB/s memory bandwidth.

That sounds like 3 memory controllers vs 4 memory controllers, likely due to chip binning. TSMC's 3nm processes supposedly still has relatively low yields.

I think it's quite clever actually, because although it's sort of a laughable technical feat compared to other options for gaming, many of the people who both have the cash to spend on the higher-end mac AND who don't pursue any more modern games on other platforms probably would have been original Myst players

> Plus they are nerfing the desktops by only offering the all-in-ones with m2 I'm confused by this statement. The iMacs leapfrogged M2. The new models shipping next month will have regular M3 chips, replacing M1 models.

sorry, it's a typo and it won't let me edit it now. I meant that they only desktop they upgrade to m3 is the iMac and all the other desktops are thousands of dollars with the old processor... so like Mac Studio for $2,000 that I need to buy to power all my monitors now is using an old outdated processor.

I wouldn’t consider the M2 outdated. My studio is running the M2 Max and it takes a lot to make it sweat. Would the M3 be better? Sure. In some ways. Is the M2 bad? Not at all. This is the best computer I’ve ever used by a wide margin, and I expect to continue using it for a long time.

I would have hesitated to get an M2 with the M3 announced, but having used one now… I don’t care very much. It’s a bit like updating your iPhone every year. It’s like 5% better and in the scheme of things, it’s not worth worrying about.

In addition to what mono said, llama.cpp allocates everything up front with "--mlock" Llama.cpp (and MLC) have to read the all the model weights from RAM for every token. Batching aside, there's no way around that.

Mlock is an optional parameter: github.com/ggerganov/llama.cpp/tree/master/examples/main#mlock
