The AMD Ryzen 5 Processor Tech Report

The AMD Ryzen 5 Processor Tech Report

9 Replies

We have all been blown away by the raw processing power of the AMD Ryzen 7 processors. Even its gaming performance proved to be quite competitive against the Intel Core i7 processors. But as exciting as the Ryzen 7 processors are, they may be out-of-reach for many people. This is where the AMD Ryzen 5 processors come in.

 

A Bigger Slice Of The Pie

AMD may have priced the Ryzen 7 CPUs very competitively against the Intel Core i7 processors, but the sub-$300 market is twice as large. So they are quickly introducing the AMD Ryzen 5 processors to try and win a bigger slice of the pie.

 

The AMD Ryzen 5 Key Features

The AMD Ryzen 5 processors will feature the same AMD Zen features as the Ryzen 7 CPUs. This includes the AMD SenseMI technology that we first revealed in The Complete AMD Ryzen “Summit Ridge” Tech Briefing.

Here is a primer on AMD SenseMI by Mark Papermaster, Senior Vice President & CTO of AMD.

The AMD Ryzen 5 processors will also be multiplier-unlocked, allowing for easier overclocking. In fact, AMD has announced that all Ryzen processors will be multiplier-unlocked. Awesome!

The AMD Ryzen 5 processors will continue to support two threads per core. The only real difference is the number of processor cores they offer.

The first slew of AMD Ryzen 5 processors will offer either 6 processor cores, or 4 processor cores :

  • the Ryzen 5 1600X – 6 cores, 12 threads, 3.6 GHz core clock, 4.0 GHz boost clock
  • the Ryzen 5 1600 – 6 cores, 12 threads, 3.2 GHz core clock, 3.6 GHz boost clock
  • the Ryzen 5 1500X – 4 cores, 8 threads, 3.5 GHz core  clock, 3.7 GHz boost clock
  • the Ryzen 5 1400 – 4 cores, 8 threads, 3.2 GHz core clock, 3.6 GHz boost clock

How Fast Is The AMD Ryzen 5 Processor?

Until the NDA expires on launch day (11 April 2017), we won’t have any hard numbers. But AMD shared a single Cinebench R15 benchmarking result with us. They compared their flagship AMD Ryzen 5 processor – the Ryzen 5 1600X, against the Intel Core i5-7600K.

The AMD Ryzen 5 1600X is a 6-core, 12-thread processor, while the Intel Core i5-7600K is only a 4-core, 4-thread processor. Even though the Intel processor has higher clock speeds (4 GHz core, 4.2 GHz boost), the Ryzen 5 processor has twice as many processor cores.

Hence, it is hardly surprising to see the the Ryzen 5 1600X beat the Core i5-7600K by 69%. The AMD Ryzen 5 1600X scored 1195, while the Intel Core i5-7600K only scored 655, in this test.

This is obviously a grossly unfair comparison… until you consider the very likely possibility that AMD intends to price the Ryzen 5 1600X against the Core i5-7600K. In fact, considering how they priced the Ryzen 7 processors, the Ryzen 5 1600X will likely be cheaper than the Core i5-7600K.

 

The AMD AM4 Platform

Like the Ryzen 7 CPUs, the AMD Ryzen 5 CPUs can be paired with any Socket AM4 motherboard. This allows for easier and cheaper upgrades if you already have an existing Socket AM4 motherboard.

However, if you wish to overclock, and take advantage of the AMD Ryzen’s unlocked multiplier, you need to use a motherboard built around the AMD X370, X300 or B350 chipset. And only the X370 and X300 chipsets allows for dual PCI Express graphics cards.

AMD Ryzen 5 Bundled Coolers

The AMD Ryzen 5 1600X does not come with a bundled cooler, but the other Ryzen 5 models will come with a bundled AMD Wraith cooler. They are quieter, feature a new spring-screw clamping system and RGB LED lighting.

The Complete AMD Ryzen “Summit Ridge” Tech Briefing

12 Replies

The AMD Tech Summit held in Sonoma, California from Dec 7-9, 2016 was not only very exclusive, it was highly secretive. The second major announcement we have been allowed to reveal is the new AMD Ryzen desktop CPU, formerly known as Summit Ridge.

Like our Radeon Instinct article, we will not only share what AMD revealed during the AMD Tech Summit at Sonoma, we will bring it to you in our videos. It will be as if you were there with us! Enjoy! 🙂

 

The AMD Ryzen Tech Briefing Summarised

For those who just want the quick low-down on the AMD Ryzen desktop processor, here are the key takeaway points :

  • The AMD Zen “Summit Ridge” processor is officially branded as the AMD Ryzen processor.
  • The first AMD Ryzen “Summit Ridge” processors will officially launch in Q1, 2017.
  • The AMD Zen-based server processor, codenamed Naples, will launch in Q2, 2017.
  • The AMD Zen-based notebook APU, codenamed Raven Ridge, will launch in H2, 2017.
  • The top Ryzen “Summit Ridge” processor SKU will have a 3.4 GHz base clock, or better. Its boost clock was not revealed.
  • The Ryzen “Summit Ridge” processors will have 8 cores and process 16 threads simultaneously.
  • The Ryzen “Summit Ridge” processors will have a 4 MB L2 cache and a 16 MB L3 cache.
  • The Ryzen “Summit Ridge” processors will feature the AMD Infinity Fabric network-centric interconnect technology.
  • The AMD Ryzen “Summit Ridge” processors will feature the AMD SenseMI sensing and adaptive technologies like :
    • Pure Power, which uses real-time sensors to support a closed-loop control through Infinity Fabric.
    • Precision Boost, which allows for fine-grained frequency control in 25 MHz increments.
    • Extended Frequency Range (XFR), that is fully automated and permits frequencies above the Precision Boost limits.
    • Neural Net Prediction, which anticipates future decisions, preloads instructions and chooses the best processing path.
    • Smart Prefetch algorithms have been greatly improved.
  • Preliminary benchmarks of the AMD Ryzen (3.4 GHz, no boost) showed that it was slightly faster than the Intel Core i7-6900K (3.2 GHz base, 3.7 GHz boost).
  • At idle, the total power consumption of the 3.4 GHz Ryzen system was about 13.5 W (12.67%) less than a Core i7-6900K system.
  • At full load, the total power consumption of the 3.4 GHz Ryzen system was about 3.8 W (1.98%) less than a Core i7-6900K system.
