Apple Introduces M3 Ultra Chip With Impressive Performance, Up to 512GB of RAM, and More
Apple today unveiled the M3 Ultra chip, its fastest Mac chip ever released. It is available in the new Mac Studio that was also announced today.

Apple says the M3 Ultra chip is essentially two M3 Max chips fused together with its "UltraFusion" technology, so the chip's specs are all doubled compared to the M3 Max. There was speculation last year about the M3 Max chip lacking UltraFusion technology, but Apple's announcement today has proven that rumor was false.
Apple:
Apple's custom-built UltraFusion packaging technology uses an embedded silicon interposer that connects two M3 Max dies across more than 10,000 signals, providing over 2.5TB/s of low-latency interprocessor bandwidth, and making M3 Ultra appear as a single chip to software.
The M3 Ultra chip features up to a 32-core CPU, with 24 performance cores and eight efficiency cores. Apple says the M3 Ultra chip is up to 1.5x faster than the M2 Ultra chip, and up to 1.8x faster than the M1 Ultra chip.
In addition, the M3 Ultra chip can be configured with up to an 80-core GPU. Apple says the M3 Ultra chip offers up to 2x faster graphics performance than the M2 Ultra, and up to 2.6x faster graphics than the M1 Ultra chip.
The chip has a 32-core Neural Engine, and it supports up to 512GB of unified RAM, with up to 819 GB/s memory bandwidth.
Like the M4 Pro and M4 Max chips, the M3 Ultra chip supports Thunderbolt 5 for up to 120 GB/s data transfer speeds on Macs with Thunderbolt 5 ports.
Apple says the M3 Ultra chip has industry-leading power efficiency in its class.
