The Ryzen brand will be applied to desktop and mobile variants. It had been formerly known as Summit Ridge. AMD has been telling the world that Ryzen is pronounced Rye-Zen (like horizon, without the “ho”). It has not said what the Rye means, but tired and emotional hacks suggested that it might be inspired by Jack Daniels – as indeed so are they.
Zen-based processors will target desktops, servers, and mobiles device, but the first wave of products will be targeted at the performance desktop market, where gamers and VR continue to spur growth. PC gaming hardware is predicted for 35 percent growth from 2015 to 2020, and VR-capable PCs are predicted to grow by a factor of 10 by 2020. Interest in eSports continues to skyrocket as well.
AMD has disclosed that one of the high-end options in the initial Ryzen line-up will feature eight cores (16 threads with SMT) and at minimum a 3.4 GHz base clock, with higher turbo frequencies. That processor will have 20MB of cache – 4MB of L2 and 16MB of L3. AMD is also hyping up what it is calling SenseMI technology. AMD’s SenseMI is a set of sensing and adapting technologies, including what AMD is calling “an artificial intelligence network” inside every Zen processor. There are five main features of SenseMI that include Pure Power, Precision Boost, and Extended Frequency Range (or XFR), along with the neural net prediction algos and smart prefetcher.
In fact, there is not that much exciting in SenseMI – it is just an updated branch predictor, prefetcher, and power and control logic in Zen. It might have some sexed up algorithms but it is not the ground breaking technology it is claimed.
AMD said that the AM4 platform for Ryzen will be have all the usual gubbins you expect to see on a modern PC enthusiast platform. AM4 motherboards will use DDR4 memory and feature PCIe Gen 3 connectivity, and support for USB 3.1 Gen 2, NVMe, and SATA Express.
Another thing that Ryzen will have is something called Pure Power which senses what’s going on with the processor’s current workload and provides a closed-loop control system to scale performance and power, over what AMD is calling its Infinity Fabric.
This monitors temperatures, frequencies, and voltage, and adaptively controls each element to optimize performance and power usage.
Another thing that Ryzen will have is something called Infinity Fabric which is interconnect technology used to link the individual bits of IP within a processor and the processor to other IO.
AMD wants this tech to scale its products, beyond moving to new process nodes, increase performance and efficiency, scale bandwidth, improve latency and the chip’s QoS.
Infinity Fabric consists of two key elements, a scalable control fabric and a scalable data fabric. The scalable control fabric has all the central control elements, with small remote elements that are dispersed in each different block of the SoC.
However the early indications suggest that Ryzen is rather good and should put the fear of Jehovah into Intel – particularly if AMD keeps the price down.
