The Ryzen x86 processor core features a 40% generational improvement in instructions per clock; AMD also unveiled new sensing, adapting, and learning technologies in Ryzen processors, to be called AMD SenseMI Technology, and based around five components [built into the processor silicon]:
- 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 25 MHz, 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 behaviour to anticipate the needs of an application and prepare the data in advance.
Jim Anderson, senior vice president and general manager, Computing and Graphics Group, AMD, commented: “The desktop market is hungry for change as new and demanding use cases like VR, 3D modelling, and eSports require intense amounts of processing and graphics power. We designed Ryzen processors to excel in these areas and to bring much-needed innovation and competition back to desktop PCs.”
AMD says that its profiling with image rendering and video transcoding demos shows that the new CPU can match or outperform the Intel Core i7 6900K – also an 8-core, 16-thread processor – in many complex creative tasks. The 140-watt TDP Core i7 6900K ran at stock processor speed and boost against a 95-watt TDP Ryzen processor at 3.4 GHz without boost, showing the computing power and performance-per-watt efficiency of Ryzen.
