For couple of months now, Samsung is recruiting engineers and specialists in the server field, from Intel, AMD or other high-tech companies. Among recruited people are well known and recognized individuals some being specialized in CPU design. It is quite clear that Samsung is preparing its entry into the Server market, but it will not be based on x86 architecture, but rather based on ARM CPUs.
The idea is floating in the air for now some times, from the first 64-bits ARM prototypes, offering up to 16 cores, such as the Cortex A15. Associated with with he appropriate software, such ARM CPU-based hardware can compete with x86 workstation, as it is possible to install several ARM CPU/machine and use them for parallel computing. With the advantages of having a low power consuming CPU architecture, and new recruits, Samsung is probably trying to optimize as much as possible its ARM Cortex A15 chips to make then as efficient as possible for a server usage.
The market could be huge, and considering that current data centers, clusters and computer farms are criticized for their huge power consumption, Samsung is probably preparing its offer for greener server solutions.
