AMD yesterday unveiled more information about its upcoming high-performance desktop processors based on the “Zen” core architecture (codenamed “Summit Ridge”). AMD revealed Ryzen, the brand which will span across “Zen”-based desktop and notebook processor families. Additionally, AMD introduced SenseMI, a set of sensing, adapting, and learning technologies built into the AMD Ryzen processor that combine with multiple other advances in architectural, platform, efficiency, and processing technology to address the demanding needs of gamers and enthusiast PC users.
“The ‘Zen’ core at the heart of our Ryzen processors is the result of focused execution and thousands of engineering hours designing and delivering a next-level experience for high-end PC and workstation users,” said AMD President and CEO Dr. Lisa Su. “Ryzen processors with SenseMI technology represent the bold and determined spirit of innovation that drives everything we do at AMD.”
AMD SenseMI technology is a key enabler of AMD’s landmark increase of greater than 40 percent in instructions per clock, and is comprised of five components:
- Pure Power – more than 100 embedded sensors with accuracy to the millivolt, milliwatt, and single degree level of temperature enable optimal voltage, clock frequency, and operating mode with minimal energy consumption;
- Precision Boost – smart logic that monitors integrated sensors and optimizes clock speeds, in increments as small as 25MHz, at up to a thousand times a second;
- Extended Frequency Range (XFR) – when the system senses added cooling capability, XFR raises the Precision Boost frequency to enhance performance;
- Neural Net Prediction – an artificial intelligence neural network that learns to predict what future pathway an application will take based on past runs;
- Smart Prefetch – sophisticated learning algorithms that track software behavior to anticipate the needs of an application and prepare the data in advance.
AMD Ryzen processors for desktops are expected to be available beginning in Q1 2017 and AMD Ryzen notebook processors are planned to launch in 2H 2017.
