Apple M7 Ultra Could Pack a Jaw-Dropping 1.5TB of RAM

The Apple M7 Ultra could get a huge RAM upgrade! Apple silicon just teased its wildest spec yet. Bloomberg’s Mark Gurman reports that Apple is preparing to include up to 1.5TB of RAM in the upcoming M7 Ultra chip, and it’s the kind of number that makes even seasoned Mac users do a double-take.

Why 1.5TB Actually Matters

This isn’t just a bragging-rights spec bump. That amount of memory would mean Apple Silicon finally matches the highest RAM configuration available on the highest-end 2019 Intel Mac Pro. For a company that solders RAM directly onto the chip package for blazing-fast unified memory, that’s always come with a tradeoff: the amount of RAM is limited by how big the chipset itself is.

More memory headroom means creators, scientists, and AI developers can run enormous on-device models without leaning on the cloud — a big deal if you care about privacy, latency, or just not paying a monthly AI subscription. If you’re tracking how Apple Intelligence and on-device AI keep evolving, this is the hardware side finally catching up to the ambition.

The Numbers So Far

There’s a real catch, though. Gurman notes it might not actually launch with 1.5TB because of the ongoing memory shortage — Apple is engineering for that ceiling, not guaranteeing it. And this won’t be cheap: based on Apple’s current RAM pricing of roughly $25 per additional gigabyte, going from a base 128GB config to 1.5TB could cost over $35,000.

Apple’s also been trimming choices at the top end lately — it discontinued the 512GB Mac Studio configuration earlier this year and then the 256GB option too, leaving 96GB as the ceiling on current Mac Studios. So a jump straight to 1.5TB would be a massive whiplash in the other direction.

The Bigger Picture

You can read Gurman’s original post on X for the full context, and Apple’s own note on the 2019 Mac Pro’s memory specs shows exactly what benchmark the M7 Ultra is chasing. This fits a pattern we’ve been covering in our Apple silicon roadmap breakdown — Apple appears to be skipping M6 Pro/Max/Ultra variants entirely and racing straight to M7 for AI reasons.

The Takeaway

The M7 Ultra is still years away, and the 1.5TB configuration is far from guaranteed. But the direction is clear: Apple wants its silicon to run serious AI workloads locally, no cloud required — and memory, not just raw processing power, is becoming the real battleground.
