It seems AMD's current 32nm server processor lineup will receive no significant updates until the second half of 2014. The roadmap reveals future high-performance and future low-power CPUs and APUs won't arrive until at least one and a half years away from now, and that AMD plans to manufacture these chips at a 28nm process.
It will be extremely hard for AMD to remain competitive against Intel in the next two years. The latter updates both desktop and server chips every year, hence, AMD will be consistently behind its larger rival when it comes to performance and features. Moreover, even when it finally launches its new chips in 2014, those products made using 28nm process technology will be competing against Intel’s chips produced at 16nm node, which will allow them to feature more cores or be cheaper to manufacture compared to AMD’s offerings.
