How much power is too much power? If you’re an anime purest, the term fusion is not new to you. The famous Dragon Ball Z characters pranced about and merged into a single being. That’s pretty much what’s happening here with the M1 Ultra processor chip. Apple says it uses UltraFusion to interconnect the die of two M1 Max chips.
What this means is that everything about the Ultra is twice as much as a single M1 max processor. Don’t believe us? Here are the numbers. It comes with up to 128GB of unified memory and a 20 core CPU, 64 core GPU, and a 32 core Neural Engine. Now you’re wondering if it was this easy to get more juice out of a processor then why were Intel and the others sleeping on the idea? Well, the trick is with the UltraFusion which uses a silicon interposer that connects the two chips across more than 10,000 signals and provides 2.5TB/s of low latency inter-processor bandwidth. In short, any software recognises the chip as a single unit and UltraFusion makes that possible. Basically, the two processors gossip with each other like Big Boss contestants to no avail.
Apple says the processor takes 90% less power compared to 16 core desktop processors in the market and consumes 200W less power than the highest-end GPU in the market. Obviously, these claims will be put to the test soon when the thing launches sitting inside an Apple Mac Studio (starting at ₹1,89,900).
