Yeah, but one of them doesn't cost a ton to implement (what they're doing) and the other one would cost them a ton through lost sales (what you're asking for).

Always follow the money :-)

Lots of junk comments, but I guess that happens with Apple announcements. Laptops seem impressive to me, I want to see the real world use metrics. Pushing hard on the performance per watt type metric and no doubt they have a lot of power and use less power. Seems like they listened to the outcry of people regarding the Touch Bar and more ports. Seems like this should sell well.

Yup, waiting for the performance review embargo to lift.

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…

Really curious if the memory bandwidth is entirely available to the CPU if the GPU is idle. An nvidia RTX3090 has nearly 1TB/s bandwidth, so the GPU is clearly going to use as much of the 400GB/s as possible. Other unified architectures have multiple channels or synchronization to memory, such that no one part of the system can access the full bandwidth. But if the CPU can access all 400GB/s, that is an absolute game changer for anything memory bound. Like 10x faster than an i9 I think?

Earlier quoted context omitted.

I think the higher memory is also a huge win, with support for up to 64gb.

400GB/s available to the CPU cores in a unified memory, that is going to really help certain workloads that are very memory dominant on modern architectures. Both Intel and AMD are solving this with ever increasing L3 cache sizes but just using attached memory in a SOC has vastly higher memory bandwidth potential and probably better latency too especially on work that doesn't fit in ~32MB of L3 cache.

The M1 still uses DDR memory at the end of the day, it's just physically closer to the core. This is in contrast to L3 which is actual SRAM on the core.

The DDR being closer to the core may or may not allow the memory to run at higher speeds due to better signal integrity, but you can purchase DDR4-5333 today whereas the M1 uses 4266.

The real advantage is the M1 Max uses 8 channels, which is impressive considering that's as many as an AMD EPYC, but operates at like twice the speed at the same time.

Erhh... I think OP gets it, he's just calling out the greenwashing.

Is there an estimate of what the externality cost is for the packaging per unit? Would be useful to compare to other things that harm the environment like eating meat, taking car rides, to know how much I should think about this. E.g. if my iphone packaging is equivalent to one car ride I probably won't concern myself that much, but if it's equivalent to 1000 then yeah maybe I should. Right now I really couldn't tell you which of those two the true number is closer to. I don't expect we would be able to know a precise value but just knowing which order of magnitude it is estimated to be would help.

Any indication on the gaming performance of these vs. a typical nvidia or AMD card? My husband is thinking of purchasing a mac but I've cautioned him that he won't be able to use his e-gpu like usual until someone hacks support to work for it again, and even then he'd be stuck with pretty old gen AMD cards at best.

The fine print:

>Testing conducted by Apple in September 2021 using preproduction 16-inch MacBook Pro systems with Apple M1 Max, 10-core CPU, 32-core GPU, 64GB of RAM, and 8TB SSD, as well as production Intel Core i9-based PC systems with NVIDIA Quadro RTX 6000 graphics with 24GB GDDR6, production Intel Core i9-based PC systems with NVIDIA GeForce RTX 3080 graphics with 16GB GDDR6, and the latest version of Windows 10 available at the time of testing.
