Not your father's currency. If you think of them as pesos, the price is easier to comprehend. Not to mention if it makes a 200k salary worker 5% more productive, its a win. (Give or take for taxes.)

It's a win for a worker who's compensated based on their work output, which is pretty much the opposite of what a salaried worker is.

Productivity is productivity, doesn't matter how one is paid.

This is about the processors, not the laptops, so commenting on the chips instead. They look great, but they look like they're the M1 design, just more of it. Which is plenty for a laptop! But it'll be interesting to see what they'll do for their desktops. Most of the additional chip area went into more GPUs and special-purpose video codec hardware. It's "just" two more cores than the vanilla M1, and some of the effi…

Could we use M1 chips on non-apple boards? If yes, I wish Apple releases these for non mac os consumption. Eg. Running linux servers in the cloud.

I hate the naming. By name alone and without looking at specs, can you tell me which is the faster chip-- the M1 Max or the M1 Pro?

The M1 Pro is faster. The M1 MAX is an M1, but with new control software which makes it keep crashing.

M1 Pro is on the cheapest model, and M1 Max is on the most expensive model. So I think you are just flat out wrong here.

How do they get 200/400GB per second RAM bandwidth? Isn't that like 4/8 channel DDR5. 4/8 times as fast as current Intel/AMD CPUs/APUs? (E.g. https://www.intel.com/content/www/us/en/products/sku/201837/... with 45.8GB/s) Laptop/desktop have 2 channels. High-end desktop can have 4 channels. Servers have 8 channels. How does Apple do that? I was always assuming that having that many channels is prohibitive in terms of…

It's LPDDR5, which maxes out at 6.4Gbit/s/pin, on a 256bit/512bit interface. It's much easier to make a wider bus with LPDDR5 and chips soldered on the board than with DIMMs.

I hope we will see this on more devices. This is a huge boon to performance.

Might even forebode soldering RAM onto packages from here on out and forever.

Steamdeck will probably have a crazy 100gb/sec ram b/w. twice of current laptops and desktops.

Well, no - they immediately followed the discrete laptop graphic comparison with a desktop graphic comparison, highlighting how much more power they draw for "the same" performance.

That wasn't for desktop graphics, it was for a top-end laptop graphics SKU (I think RTX 3080 Mobile on a ~135W-150W TDP configuration?). Otherwise the graph would extend all the way to 360W for a RTX 3090.

Yup - I misheard while watching.

The chart only shows a line up to about 105W, so it's not clear what they're trying to represent there. (Not that there's any question this seems to be way more efficient!)

These things came at a great time for me. My late-2014 MBP just received its last major OS upgrade (Big Sur), so I'm officially in unsupported waters now. I was getting concerned in that era from 2015-2019 with all the bad decisions (butterfly keyboard, no I/O, touchbar, graphics issues, etc.) but this new generation of MacBooks seems to have resolved all my points of concern.

On the other hand, my late-2014 model is still performing... fine? It gets a bit bogged down running something moderately intensive like a JetBrains IDE (which is my editor of choice), or when I recently used it to play a Jack Box Party Pack with friends, but for most things it's pretty serviceable. I got it before starting university, it carried me all the way to getting my bachelor's degree last year, and it's still trucking along just fine. Definitely one of my better purchases I've made.

> I'll be very curious to see those comparisons picked apart when people get their hands on these, and I think it's time for me to give Macbooks another chance after switching exclusively to linux for the past couple years. I really enjoy linux as a development environment, but this is going to be VERY difficult to compete with..

You can always run Linux in a VM too

That's just not the same.

That sound like HBM2, maybe HBM3 but that would be the first consumer product to include it afaik. Basically the bus is really large, and the memory dies must be really close to the main processing die. Those memory were notably on the RX Vega from AMD, and before that on the R9 Fury. https://en.m.wikipedia.org/wiki/High_Bandwidth_Memory

If that were the case you could probably see an interposer. And I think the B/W would be even higher.
