So we have posted a thing or two already about Ryzen being released as 4 and 8 core processors. AMD will release an 4 and 8-core model with and without hyper-threading. 

Info comes from Thai based zolkorn indicated that AMD only can release 4- and 8-core models both with and without hyper-threading. The explanations is as follows, the Ryzen processors are build out of partitions that each have 4 physical cores in one module. Traditionally they had a dual-core setup so an 8-core version had four of these which could be activated and disabled per module.

New information now has been posted at io-tech.fi from our good buddy Sampsa. He claims to have confirmed from an extremely reliable source that AMD's Ryzen CPU can be configured as 6-core model. 

We have confirmed from our sources that AMD’s upcoming Ryzen processor can be technically configured as 6-core model. It is possible to disable each CPU core separately together with dedicated L2 cache from CCX without affecting shared L3 cache.

Possible L3 cache configurations are 1/1 (8 MB), 1/2 (4 MB) or completely disabled. Basic rule is that both CCXs should have similar CPU core and L3 configuration for example both should have 3 cores and full 8 MB L3 cache enabled (6C & 16 MB L3). We believe AMD will launch 6-core model of Ryzen CPU. If they don’t, it will be due other reasons than technical limitation of CCX.

One thing is certain though, we'll see four and eight core models with SKU differences in HT, clock frequencies and TDPs at launch. Then four core mainstream and higher specced parts will get unlocked multipliers. And sure, perhaps we'll see a six-core / 12-treaded part in there as well.

At the end of this month more info should become available with a launch in early March.

Six Core AMD Ryzen Processors Might Still Possible
