What this article fails to point out is the significance this plays in server/workstation side rather than desktop side.
ARM has been trying to get into the server market for awhile and there is definitely applications that can benefit with ARM over x86. What this article also fails to mention is that TSMC has signed a deal with ARM to produce the first 7nm devices. This is significant because TSMC will beat Intel (for the first time I believe) to market with a new feature size. Intel is expected to enter the 7nm market a few quarters after TSMC. If this is timed correctly with the release of the 15th Generation of Server and Workstation platforms, ARM could start creating its own market or take small bits from x86.
Windows Server ARM edition is in trials and could have a fully working OS by this time.
it did mention HPC that is assuming what i thought they were going after more then say cell phones or cheap single board pc's. the way i took it is it would be an extension of the current instruction set but a provisions for HPC environments for multi cpu setups.
i mean a server with an octor core controller what possibly up to 16 or more separate cpus with quad or octo cores that can be turned off and on as needed. sounds like a killer ECO_HPC to me if that is in fact what they are doing and after. arm's lower power and TDP vs intel/amd i think gives them a big advantage, only thing that is lacking is software to take more advantage of the HW arm is putting out. i remember reading about the battle of risc vs x86 back in the day, risc just seemed the better way to go. however X86 had more software for it and cpu speeds were increasing at a faster pace then Risc cpus which is a bit of a shame. that is after all what mac's power pc cpus were based on from Motorola back in the day. then apple finaly gave in and went to intel hw since the power pc cpus just couldnt match them any more more or keep pace with clock speed increases.
Apple A10 is I believe a very good ARM PROC. ARM can have a variety of flavors to its ISA depending on which IPs are being implemented. So you can design a very good ARM chip, but not consistently across multiple companies.
