Apple’s new M1 Ultra chip explained: The world’s most powerful personal chip

Apple has announced an all-new chip to rival its current models and competitors, the M1 Ultra, it’s the next giant leap for Apple’s silicon and the Mac.

Featuring UltraFusion, Apple’s innovative packaging architecture that interconnects the chip of two M1 Max chips to create a system-on-chip (SoC) with unprecedented levels of performance and capability. The M1 Ultra delivers mind-blowing computing power to the new mac studio while maintaining peak performance per watt.

The new SoC consists of 114 billion transistors, the most ever recorded in a personal computer chip. M1 Ultra can be configured with up to 128GB of unified high-bandwidth, low-latency memory accessed by the 20-core CPU, 64-core GPU, and 32-core neural engine, delivering amazing performance for developers compiling code, artists working in huge 3D environments that were previously impossible to render, and video professionals who can transcode video to ProRes up to 5.6 times faster than with a 28-core Mac Pro with Afterburner.

Revolutionary UltraFusion Architecture

The basis of M1 Ultra is the extremely powerful and energy-efficient M1 Max. To build M1 Ultra, the dies of two M1 Max ships are connected using UltraFusion, Apple’s custom packaging architecture. The most common way to increase performance is to connect two chips through a motherboard, which usually results in significant trade-offs including increased latency, reduced bandwidth, and increased power consumption.

However, Apple’s innovative UltraFusion technology uses a silicon interposer that connects the chips across more than 10,000 signals, providing massive low-latency inter-processor bandwidth of 2.5 TB/s, more than 4 times the bandwidth of leading multi-chip interconnect technology. on the market today…

This allows the M1 Ultra chip to behave and be recognized by software as a single chip, so developers don’t need to rewrite code to take advantage of its performance. There has never been anything like it.

Unprecedented performance and energy efficiency

The M1 Ultra features an extraordinarily powerful 20-core processor with 16 high-performance cores and four high-efficiency cores. It delivers 90% better multithreaded performance than the fastest 16-core PC desktop chip available in the same power envelope. Additionally, M1 Ultra achieves maximum PC chip performance by using 100 watts less. This amazing efficiency means less power is consumed and the fans run quietly, even when applications like Logic Pro are performing demanding workflows, such as processing massive amounts of virtual instruments, audio plug-ins and effects.

For the most graphics-intensive needs, like 3D rendering and complex image processing, M1 Ultra features a 64-core GPU, 8 times the size of M1 delivering faster performance than even the most PC GPU. high-end available while using 200 watts less power – frankly, that’s a bit unbelievable of engineering.
