AMD Ryzen Performance Incrase from SenseMI

Ryzen is AMD’s latest CPU offering aimed at directly competing with Intel’s i series processors. Staying true to what we have come to expect from AMD; the new Ryzen is overall lower priced compared to their Intel counterpart. Not only that, but the chips actually perform quite well.

This is thanks to the Zen architecture and the new AMD SenseMI Technology, which is the backbone to Ryzen.

When explaining the Zen architecture, AMD stated that AMD’s high-performance x86 Core “Zen” architecture delivers >52% improvement in instructions-per-clock cycle over the previous generation AMD core, without increasing power.

The big performance increase from SenseMI is broken down into five primary parts:

Pure Power – Works by monitoring CPU temperature and adjusting the power consumption on the fly. This helps the chip stay cool while not inhibiting speed when it is needed.

Precision Boost – Adjusts the CPU’s clock speeds at 25Mhz increments in real time to optimize performance.

Extended Frequency Range – Detects if the CPU is being cooled by air, water, or liquid nitrogen and is able to adjust the clock speed up to 100Mhz beyond what Precision Boost is able to do. This feature is not available on all Ryzen processors.

Neural Net Prediction – AI that maps out how different programs utilize the CPU to provide better performance.

Smart Prefetch – An algorithm that learns how applications function and is able to pre-load data on the CPU in the order that it anticipates will provide the best performance.

It is important to note that Ryzen does require DDR4 memory as well as a new AM4 socket.
