In addition to yesterday’s MacBook Air announcement, Apple dropped a two-fer: A new Mac Studio with an M4 Max and an unexpected M3 Ultra configuration.

First, the new chip. A new M3 variant is a surprise in itself; I assumed—as I think most people did—that any new chip configurations would be based on the M4. It appears, though, that there won’t be an “M4 Ultra”: Apple told Ars Technica “not every chip generation will get an ‘Ultra’ tier,” and French technology website Numerama (via Mac Rumors) was told “there are no UltraFusion connectors on the M4 Max chip” (Safari-translated from the original French), making an Ultra M4 physically impossible.

That’s a bummer (and makes me wonder about the future of an M4-based Mac Pro), but the M3 Ultra is a beast of a chip:

Apple today announced M3 Ultra, the highest-performing chip it has ever created, offering the most powerful CPU and GPU in a Mac, double the Neural Engine cores, and the most unified memory ever in a personal computer. M3 Ultra also features Thunderbolt 5 with more than 2x the bandwidth per port for faster connectivity and robust expansion. M3 Ultra is built using Apple's innovative UltraFusion packaging architecture, which links two M3 Max dies over 10,000 high-speed connections that offer low latency and high bandwidth. This allows the system to treat the combined dies as a single, unified chip for massive performance while maintaining Apple's industry-leading power efficiency. UltraFusion brings together a total of 184 billion transistors to take the industry-leading capabilities of the new Mac Studio to new heights.

And:

In fact, M3 Ultra is built for AI, including ML accelerators in the CPU, Apple’s most powerful GPU, the Neural Engine, and over 800GB/s of memory bandwidth. AI professionals can use Mac Studio with M3 Ultra to run large language models (LLMs) with over 600 billion parameters directly on device, making it the ultimate desktop for AI development.

The AI power in this chip makes me wonder if it (or something like it) powers the Private Cloud Compute servers scheduled to be built in Houston, TX.

On to the new Mac Studio itself:

Apple today announced the new Mac Studio, the most powerful Mac ever made, featuring M4 Max and the new M3 Ultra chip. The ultimate pro desktop delivers groundbreaking pro performance, extensive connectivity now with Thunderbolt 5, and new capabilities in its compact and quiet design that can live right on a desk. Mac Studio can tackle the most intense workloads with its powerful CPU, Apple’s advanced graphics architecture, higher unified memory capacity, ultrafast SSD storage, and a faster and more efficient Neural Engine.

The M4 Max Mac Studio is a significant upgrade and readily induces lust, but the M3 Ultra Mac Studio is just off the charts:

It delivers nearly 2x faster performance than M4 Max in workloads that take advantage of high CPU and GPU core counts, and massive amounts of unified memory.

That “massive amounts of unified memory”?

Mac Studio with M3 Ultra starts with 96GB of unified memory, which can be configured up to 512GB — the most unified memory ever in a personal computer — and up to 16TB of ultrafast SSD storage, so content and data can be kept locally.

I’ve been trying—and failing—to recall the last time Apple introduced a computer where the highest configuration was powered by a faster version of a previous-generation chip. It may well be unprecedented.

The M3 Ultra allows the Mac Studio to accomplish some mind-blowing feats, including driving up to eight Pro Display XDRs, and playing back up to 22 streams of 8K ProRes 422 video.

I would love to see that rig!

With great power comes great responsibility… for your credit card. The base M3 Ultra starts at $3,999 (compared to a paltry $1,999 for the M4 Max) and maxes out (ultras out?) at $14,099. Whew.

Pre-orders have already started, with availability beginning March 12.
