Apple’s Peak Performance launch event was a huge blast with a plethora of products at its disposal. Apple released one of the most powerful processors at the event dubbed as Apple M1 Ultra which is more powerful than a leading Intel processor. It is essentially an M1 Max on steroids given the fact that it is made up of two M1 Max processors joined together with a technique called UltraFusion.
Apple’s M1 Ultra uses innovative UltraFusion technology
The Apple M1 Ultra processors are essentially two M1 Max chipsets attached using a new technique called UltraFusion that connects to the two dies as one. Applications running on M1 Ultra will recognize it as a single processor and not two.
The SoC sports a whopping 114 billion transistors, up to 128GB of high-bandwidth and unified memory with low latency among others. The chipset can be configured to support 64-core GPU, 20-core CPU, and 32-core Neural Engine.
Talking about the SoC, it can transcode video up to ProRes at up to 5.6x faster compared to a 28-core Xeon Mac Pro. The interposer mounted on M1 Ultra that the UltraFusion uses connects 10K+ signals between the two chipsets with a 2.5TB/s low latency bandwidth between the two chipsets which raises the stakes given the fact that it is 4x higher bandwidth than any leading interconnect technology available now.
The chipset can handle up to five displays with four 6x Pro Display XDR and a fifth 4K display onboard. It supports up to 18 8K ProRes 422 video simultaneously. Talking about its GPU, the M1 Ultra uses a 64-core GPU which is eight times larger than the one on Apple’s entry-level M1 chipset. It is able to support a memory bandwidth of 800GB/s which is simply phenomenal.
