Doesn't say a lot. It's mostly speculation, the chip is listed here [1]. Notable info: Still at 5nm; double the GPU cores. Reports up to 3 displays, so it's safe to assume 2+1 external/internal. 8 High perf cores and 4 little perf cores. PCIE gen 4, no idea about number of lanes.

M1 Macs have been shown to drive 6 displays, so this "3 displays" means "3 4K/5K displays" I supposed.

The other thing is RAM. Apple still has delusions of gimping it's buyers into 16/32GB for "Pro" level machines. I'd probably buy a 16" MBP with this chip if I could get it with socketed 64/128GB. But Apple's going to solder it to the board and charge a premium even if they did.

Yeah, I'm calling it now - no chance of 128GB in a Macbook Pro. 64GB even is doubtful.

You can't even get above 16GB with the M1. You can with the i9. It took me MONTHS to receive my 16GB M1.

Obviously fake. The CPU Monkey "benchmarks" are just the M1 values multiplied.

And the single core performance benchmarks are exactly identical which would mean there would have not been any optimization compared to last gen. Not very realistic.

To be fair this would make a lot of sense. This isn't a new generation of CPU, it's a bigger variant of the existing M1.

Rules change. I've got one of the 16GB RAM Macbook Pros. They've got it acting like it's L2 cache instead of RAM as we know it, so the place where you need more than 128G becomes, well, the SSD, your mass storage. These things already don't act as if it's RAM as we're used to considering it. They could probably have shipped the first ones with 4G RAM and had 'em act relatively normal… with heavy stuff like 4K video e…

>They've got it acting like it's L2 cache instead of RAM....... These things already don't act as if it's RAM as we're used to considering it. Please stop this non-sense on HN. DRAM is DRAM. L2 Cache is L2 Cache. Doesn't matter how good its 8-Channel LPDDR4X Memory Architecture sitting next to the Die in the same package it is still just DRAM.

As someone that runs Kubernetes on my work laptop, all the "the memory architecture is different, so 8GB is enough" nonsense just doesn't hold up. I need a ton of memory FULL STOP. It sounds just like the nonsense Apple was spewing about MMS messaging on the original iPhone.

I'm pretty sure Apple knows what machines it sells, including to video and audio pros, and knows how many of them buy the 32GB options where they're available (in Intel).

Besides "Pro" is just a branding, not a class of machines designed for specific tasks with any specific guarantees.

Up until now, "pros" did just fine with 16GB or up to 32GB max on their Intel Mac laptops, so I'm not sure how "twice as fast" machines, at lower price, with the same 32GB RAM (but much more efficient use of it, closer to the CPU) will suddenly be a problem.

Especially if hardly any buy PC laptops with 64GB of RAM anyway -- and Apple doesn't, and has never, competed with custom tower PC rig makers, but to people looking at the sweet spot of portability, power, battery life, size, weight.

Well, I got mine in 2 days, so...

Then buy something else, full stop.

Intel should be scared of its own failures. Apple is merely a competitor that didn't fall asleep.

Also Apple didn't have to do ~80% of what Intel has to do - you know, the actual building of chip fabs as well as chip design. "merely" LOL.

Wouldn't that make Apple even smarter and more efficient?

People should stop comparing Apple Silicon to Intel and start comparing it to AMD.

There is no Macbook with AMD processor, I think that's why it is compared to Intel, that plus Intel being the historic leader

There is no Macbook with AMD processor because Apple didn't want to make it.

Intel is not the leader for 5+ years now.

It'd look less bad for AMD, but still wouldn't look brilliant. aarch64 allows some tricks that are much harder to pull off on amd64.

AMD still generally outpertforms Apple Silicon despite larger lithographies, so I don't really see it.
