Chips with an “X” designation at the end support SenseMI’s Extended Frequency Range technology more than the others. Smart Prefetch works hand-in-hand with Neural Net Prediction, identifying how your applications behave and preloading data that it expects you to need for faster performance.Įvery AMD Ryzen processor can also be overclocked with a compatible motherboard.Neural Net Prediction examines your usage and “primes your processor to tackle your app workload more efficiently.”.At Ryzen’s launch XFR only adds a paltry 100MHz overclock in chips. Extended Frequency Range (XFR) can nudge clocks speeds past their official maximum if Ryzen detects advanced CPU cooling, such as liquid-cooling or liquid nitrogen, for your chip.On the flip side, Precision Boost offers fine-grained, automated frequency control that can nudge performance up by 25MHz increments (versus 100MHz for Intel) to boost performance without consuming more power.Pure Power measures hundreds of on-chip sensors to optimize temperatures and power use while maintaining performance.Icons for the various SenseMI technologies.ĪMD imbued Ryzen chips with SenseMI technology consisting of separate parts: Pure Power, Precision Boost, Extended Frequency Range (XFR), Neural Net Prediction, and Smart Prefetch. The rest of the Ryzen 5 lineup consists of quad-core, 8-thread CPUs, with the $174 Ryzen 5 1500X hitting 3.7GHz with boost and the $169 Ryzen 5 1400 hanging between 3.2GHz and 3.4GHz. The $189 Ryzen 5 1600 is a 6-core, 12-thread chip that tops out at 3.6GHz. The $219 Ryzen 5 1600X is a 6-core, 12-thread processor capable of boosting to 4GHz, the same max speed as the Ryzen 7 1800X. The more affordable Ryzen 5 series launched on April 11 with more variation among processors than you’ll find in the 7 series, then also received some price reductions at CES 2018. The Ryzen 7 lineup consists of the $350 Ryzen 7 1800X, the $309 Ryzen 7 1700X, and the $299 Ryzen 7 1700 following permanent price cuts for many of AMD’s CPUs at CES 2018. The top-of-the-line Ryzen 7 processors launched first, with 8 cores, 16 threads, and price points that undercut the comparable 8-core Intel Extreme Edition by a whopping $500. AMD’s mainstream Ryzen chips are split across three families.
