Apple’s Peek Performance event has come and gone. Other blogs will discuss the minutia of the event, so I won’t attempt that here. Instead, I’m going to focus on the highlights – mostly Apple Silicon.
As not to bury the lead, the star of the event was the new M1 Ultra chip. This is a professional-class desktop chip that builds on the M1 Max available in the current crop of MacBook Pros. M1 Ultra is essentially two M1 Max chips fused together using a new “Ultra Fusion” process. M1 Ultra provides for 2.5 TB/s interprocessor bandwidth, 800 GB/s of memory bandwidth, has 114 billion transistors, has up to 128 Gb of unified memory, includes a 20 core CPU, and includes a 64 core GPU. Most of Apple’s chips have a combination of high performance and efficiency cores. The Ultra is no different, but the balance has shifted. M1 Ultra has 16 performance cores and 4 efficiency cores because this is made for desktops using AC power.
