They offer the ARM Cortex-A15 SoC the server market

In recent months, both Intel and teeth are showing each other whenever they can, each claiming to have advantages over the other , but Intel went further to consider a fad ARM as old competitors like Transmeta .

The reason for the aggression between the two is that both seek to expand its business segments dominated by the other, making them competitors, which is good news for us as users (more competition = better products and lower prices). ARM, a company that dominates the segment of smartphones and tablets, is hard to enter the market of desktop computers, laptops (notebooks and smartbooks) and (servers low power), x86-dominated areas, and to This last segment touts the following advantages of Cortex-A15 SoC:

  • performance between three to five times that of its previous products based on Cortex-A9 (thanks to the combination of higher yield per cycle and higher frequency of operation).
  • Very consumption, 60% lower than the Cortex-A9 thanks to 32nm manufacturing process, but ARM expects to improve the relationship with their future Cortex-A15 SoC made manufacturing processes 28 and 20nm.
    Support in up to four cores per SoC, and up to 16 per SoC using ARM technology CoreLink CCN-504 and DCM-520 (and thousands of them using multiple interconnected nodes).
  • Hardware support for floating point arithmetic calculations on average, single and double precision.
    Hardware virtualization.
  • LPAE Mode (Large Physical Address Extensions), through which they can access up to 1TB of memory (with support for parity and ECC “Error Correcting Code”).
  • High security (thanks to its technology TrustZone).
  • Very low price. ARM Cortex-A15 SoCs with prices from U.S. $35 to U.S. $50, compared to several hundred dollars that cost North American CPUs from Intel and AMD.

There are all advantages for ARM, Cortex-A15 it does not support 64-bit instructions, but has other ARM SoC as Atlas (ARMv8) which does support 64-bit instructions and is capable of addressing major figures of DRAM. Another issue to mention is that while there are distributions support ARM focused on servers, there is still some version of focused servers (Windows RT is focused on tablets, notebooks and desktops).
