One last post before we call it a night. Asian tech site Coolaler claims it received details about how AMD's Ryzen lineup will look like. This is an unverified rumor so as usual I recommend to take it with a grain of salt.
The site reports Ryzen will consist of R3, R5 and R7 series processors, which is consistent with earlier rumors. If this rumor pans out, the low-end Ryzen chips will the R3 1100/1200 series, these are quad-core parts without simultaneous multithreading (SMT) so they are limited to four threads.
A bit higher in the hierarchy we have the R5 1300/1400 series, these are quad-core parts with eight threads. Next we have the R5 1500/1600 series, these have six cores and twelve threads. The high-end consists of the R7 1700/1800 series, which offers eight-core, sixteen-threaded processors.
We're not sure what the X and PRO versions are. Perhaps the X models are more suitable for overclocking, but we already know that all Ryzen processors should have an unlocked multiplier. Unless AMD surprises us with something new, my guess is the PRO versions are parts for the business market, that would fit with AMD's modus operandi.
The table below shows the Ryzen lineup and provides a clue about how these chips will be positioned versus Intel's CPUs in terms of performance.
Ryzen is expected to be available on March 2 but the initial launch lineup is rumored to consist solely of R7 series CPUs. Other versions will reportedly follow at a later date.
