By bringing ARM architecture to the forefront in desiging CPUs for servers, I think AMD sees a development of heterogenous architecture at the data center level, similar to bigLITTLE processing by ARM. For this, the software ecosystem has to be tweaked and enterprise architecture is an environment that can see wide fluctuations in compute demands.
AMD is looking to prepare itself for a variety of compute demands and a great deal of fluctuation by creating a heterogeneous architecture. ARM is going to experience a wave of products based on its solution that will disrupt the traditional x86 stranglehold on the market. But with both X86 and ARM architectures, AMD is equipped to provide the kind of variety they will need to remain competitive in 2014 and beyond.
Intel PE is 13. It is low comparing with other Semiconductor Company.
You might be right about me to be pessimistic. I am not sure server market will gown, in term of revenue, significantly in next 6/7 years for 3 reasons:
1. I am seeing those traditional servers buyers, such as Google, Facebook, are migrating to their in-house solution slowly. Those are not always x86 solution.
2. With more companys moving to clould and virtualization, less servers are required due to high server utilization;
3. x86 servers are mostly built for general purpose server. The power efficiency and cost efficiency are horrible. I'm seeing more purposefully built servers which could be accelerated by ASIC, FPGA, or even GPU. For power perspective, ASIC is 1000x more power efficient than x86, even FPGA is 100x better in lots of cases. Most of those purposefully built servers are likely ARM based SOC product, with lots of purposeful built acceleration engine direct target to its applications.
