Welcome to the Official AMD Ryzen MegaThread! This thread will be the main location for all Ryzen discussion and information!
Thread has been updated on 3/5/2017.
This thread serves as the primary discussion thread for all Ryzen information and resources. While discussing, please remember to stay within the guidelines set by Tom's Hardware and above all, DO NOT start a flame war.
AMD Ryzen is the next generation of CPUs coming from AMD. It has been a LONG awaited arrival since the failure of the FX CPUs that launched several years ago. Ryzen plans to fix everything that was wrong with their previous architectures, including single core performance and energy efficiency.
Official Pricing for the Ryzen R7 CPUs starts at $329 for the 1700, $399 for the 1700X, and $499 for the 1800X. Ryzen 5 and Ryzen 3 pricing are unknown at this time.
Pre-Orders Began on Feb 22. Official launch is March 2nd.
Performance for Ryzen as of now seems to be hit or miss. Ryzen is performing very well in highly threaded tasks however in gaming it seems to be taking a downfall vs mid range/high end core i5 and i7s.
The good news is that this architecture is new (VERY new), meaning that optimizations and patches should fix these performance issues with gaming. AMD has said it's working with dozens upon dozens of numerous games developers and programmers to get Ryzen optimized for the latest titles Intel is dominating on so far. (Unsuprising due to the fact that for the past 4 years there was no AMD competition, meaning developers didn't need to optimize for AMD.)
Overclocking has also been somewhat of a shock, Ryzen is by far one of the worst overclockers in CPU history. From what reviewers are saying, roughly 90% of all 1800X CPUs can only make it to 4.0ghz or less. Only a very small portion of 1800X chips can even hit 4.1ghz. (Note: This is with SMT on and ALL cores enabled. If you disable SMT and/or disable some cores, you will get higher overclocks.) However, if Intel was able to optimized their finFET 14nm tech to allow higher clock speeds (ie. Skylake vs. Kaby Lake), what's not to say AMD won't be able to do the same thing.
I want to point out that Ryzen is still a VERY good CPU. It seems like a lot of people are hating on Ryzen simply because it can't game well (specifically at 1080P). I will agree with them to some point, because from the AMD demo's prior to Ryzen launching, AMD seemed to be saying their Ryzen chips were great at gaming.
However, these CPU still do deliver in the productivity department. You still get 90% of 6900K performance for only 50% of the price (with 1800X). So if your a guy who needs lots of threads, Ryzen is still the best buy for you.
Unfortunately, memory support on Ryzen for high speed RAM --and more specifically-- high speed quad channel kits is very poor. Ryzen's memory controllers top out at just shy of 3000mhz with only two sticks, with 4 sticks, the speeds go down to roughly the 2666mhz range. Compare that with Intel Kaby Lake and Broadwell-E which can easily handle 4000mhz RAM without a problem.
As a WARNING for new PC builders, DO NOT get high speed RAM in excess of 2933mhz for Ryzen at this time. Or it is pretty much guaranteed that you will suffer instability.
AMD has been able to pull out an amazing 52% IPC improvement over their previous architectures. Allowing Ryzen to compete directly with Skylake/Kaby Lake.
AMD has also introduced a smart system for loading specific instructions called “Neural Net Prediction”. This tech anticipates future decisions and pre-loads the right instructions for the specific job.
Another smart feature AMD is introducing is called “Precision Boost”. It seems very similar to Nvidia’s GPU Boost technology. What it does is improve the core clock on 25mhz increments and also increases power on a similar basis. Basically, it operates like Turbo Boost/Core but has the capability, like GPUs, to dynamically boost in 25mhz increments, compared to CPUs which only have several clock speed steps.
This also ties in with the power delivery called “Extended Frequency Range (XFR)”. If you have a high end air cooler or liquid cooler, AMD Ryzen can smartly accommodate for the extra cooling capability and increase both voltage and core clock even higher than normal. Again, very similar to GPU Boost (specifically rev 3.0).
AMD has also introduced a new hyperthreading technology that isn't like their previous SMT on piledriver. It works very similarly to Intel's hyperthreading. Without getting too nerdy, AMD's new hyperthreading fixes the problems of the older architecture by not sharing as much resources between cores, instead giving them their own "tools" to play with. Allowing single core performance to stay high.
News and Future Updates
So far, AMD has said that their Ryzen 5 CPUs will be coming in the 2H of 2017, and their Ryzen 3 CPUs will be out in Q3 or Q4 of 2017.
