M1 had 70 GB/s, M1 Pro: 200, M1 Max 400, M1 Ultra 800.
Modern RTX 6000: ~1,600 or so.
If we get a 1,200-1,500 GB/s bandwidth M7 variant in late 2027 with 512GB of RAM, that will be a very interesting chip. Tracking LLM size and performance improvements, I can imagine that being a sort of inflection point for local inference. I wonder what the power budget would be in desktop format.
You're look at about 100 tokens/s for a 1T MoE 37B active 4bit model.
It'd probably cost $30k or more I'm guessing if memory prices do not come down. Even at $30k, it could still be a relative bargain since an RTX Pro 6000 Blackwell 96GB card costs $12k today. The M3 Ultra with 512GB was around $8k before Apple discontinued it. I expect an M7 Ultra to have 768GB or 1024GB.
Apple Silicon Macs were on their way to becoming cheap local LLM machines relative to professional GPUs before this memory crisis. It may still emerge as such in a few years.
Here's some interesting math: At 512GB, an Ultra chip could make 42 pro iPhones. Assume a 55% profit margins, and $1200 ASP, you're looking at $28,160 in profit from making iPhones instead. No wonder Apple discontinued the M3 Ultra 512GB. If they only have a limited supply of RAM for all their products, it makes no sense to produce an $8000 M3 Ultra 512GB when you can produce 42 pro iPhones. You can only configure an M3 Ultra up to 96GB today as of June 2026.
Apple would have to raise the price of a 512GB Ultra Mac to around $50k to match iPhone profits.
How would that work? They purchase 512GB from Samsung and then it doesn't matter if that's like 128x 4GB or 4x 128GB?
Edit: for those of you downvoting I don’t celebrate this prospect. I’m merely realistic about where things are going given the rapid vibe shift from the administration on AI since the start of June.
(This is assuming Apple will deliver, but this area is one of the biggest ones they have in AI, and they need the developer ecosystem to exist and survive)
That means they're actually incentivized at least short term, to benefit PCs becoming strong enough to do local LLMs. Which makes this play make even more sense. Though, I've been saying for a while that the local AI inflectiom point is the death knell for these frontier labs.
Maybe this strategy works, even in that world.
Remember when we all thought (were told we thought) the world was heading to 3D views of our 2D lived experience like a solid Cube of GUI we could rotate around and live inside? Well Apple took the simple 2D square pane of virtual desktops and .. made it a SONY strip. One variable: sideways.
So here we are being told AI is the future. Apple seems to be saying "yes but it will run local" which might be a safe bet if AI comes true but I wonder how many of us want the AI outcome, which is morally speaking the 3D immersive GUI cube here: what if we don't want that?
So I think Apple has the right instinct. In fact, I've had the thought multiple times that I really want a lot of workflows just running on my device. Workflows like fast vector search (already fast on the m4, but I want it more common place), or realtime transcription and summarization to be even faster, on device, etc.

Given the risks involved in establishing Apple Silicon designs with a new fab, I would expect early M7 parts to be in test production right now.
The fundamental M7 design is already set in stone.
Mark Gurman's Bloomberg article does not mention fabrication partners or processes.
The M7 Pro and M7 Max are scheduled for as early as the end of 2027, while the M7 Ultra is on track for 2028.
I was holding out for one until I decided to switch from an M1 Pro 16" MBP to an M5 Air 15" due to the expected price increase. I think many M1 Pro/Max generation people were waiting to upgrade this year.
They can release a redesigned MBP with the base M6 chip.
They don't want to tell the world how the new redesigned MBP is the best laptop in the world but it's slower than the older MBPs.
> What sets the A20 apart isn’t just the node shrink—it’s the revolution in packaging. Apple is transitioning to Wafer-Level Multi-Chip Module (WLCM) integration, meaning that RAM will no longer be situated beside the chip, but rather on the chip wafer itself, integrated alongside the CPU, GPU, and Neural Engine.
This shift eliminates the need for silicon interposers and substrates, thereby enhancing signal integrity, improving thermal dissipation, and facilitating faster memory access with lower latency. The benefits? Better multitasking, smoother AI processing (hello, Apple Intelligence), improved battery life, and potentially a smaller chip footprint—freeing up space for other components.

It's entirely possible that TSMC is ramping up more slowly than expected.
And their explanation isn't really passing the smell test for me for other reasons, for instance the fact that DRAM processes are pretty radically different than bulk logic processes, which wouldn't really let you put it all on the same wafer, much less the same die. Even back in the day when you had eDRAM blocks (like the Xbox 360's eDRAM die), that was really a DRAM process with a bit of logic cells that wouldn't be competitive if they weren't sitting right next to the DRAM blocks.
I could be wrong here though, my examples are more than a bit long in the tooth.
As someone who wants to run effective llms locally for many things their other big benefit has been the unified memory studios for a small bit.
But in terms of “noticing it” you are correct. You won’t pay attention after a day or two.

I wonder how much the rumored 768GB RAM version will cost.

It's not simply marketing since the Pro/Max chips of a generation use the same cores as the regular version, just more of them or different combinations of performance and efficiency cores.
The claim is that M6 will be released, but the only variants will be lower end.
When they get to the M7 generation, they will make high end variants.
It's a real distinction because each generation of parts shares an architecture.
The article has an entire section speculating what the M6 parts will be, but says they'll top out around 200GB/s memory bandwidth and 12 graphics cores.
Why would it? Each generation of the M series has an architectural improvement on their chipsets. The difference between an M1 and an M1 Pro is the allocation and arrangement not the architecture. M6 to M7 presumably will have architectural changes.
Or did this announcement also add an M6 chip, and they're just skipping pro?
It can still be a very real, not made-up distinction, if the actual facts on the ground are that Apple designed an M6 line, but then scrapped that design and asked the team to create a new design with emphasis on AI-focused specs.
It's not the name that's important (the M7 could still come out as M6), is them skipping a design, or cpu "Tick-Tock model" step.
It's the same thing as how the Mac Studio got an M4 Max refresh, but they didn't make an M4 Ultra so if you want the 28+ core CPU or 60+ core GPU, that's still using an M3 Ultra.
This time it'll be across all the Pro, Max, and Ultra versions, if you want those they'll stay at the previous generation for the M6 cycle.
Not that weird - Apple has a huge set of chips and hardware and software products. Putting every single thing on a fixed identical update cycle together won't always make sense.
Are you thinking Apple is leaking that there will be a long wait for much more expensive chips in order to… what?
If comapnies keep spending half a macbook neo worth of subscription on AI plans monthly per person, Apple is going to have a hard time competing.
