ARM announces cores roadmap for PC processors
The two processor cores to follow on from the current Cortex-A76 are codenamed Deimos and Hercules; the first is targeting 7nm manufacturing processes while the second could be built in either 7nm tor 5nm.
Deimos due to be delivered to licensees in 2018 is expected to provide a 15 percent or better increase in computational performance from both architectural and manufacturing process changes.

Hercules will become available to licensees in 2019 and is expected to provide a further improvement in performance while improving power and area efficiency by 10 percent. These gains are on top of any gains achievable from use of the 5nm process node.
ARM has made the point that this is the first time it has shared roadmap information with the public but does not explain why it has chosen to do so now and for this line of processors. ARM argued that the advent of 5G cellular communications would change the levels of performance and efficiency required from personal computers.
However, Nandan Nayampally, general manager of the client business unit at ARM, said that the roadmap combined with innovations by licensees and foundry partners would enable ARM-based processors to break the dominance of Intel’s x86 processor architecture and “gain substantial market share in Windows laptops and Chromebooks over the next five years.”

Nayampally pointed out that Windows 10 based systems powered by Qualcomm Snapdragon SoCs are already available from Asus, Lenovo and Hewlett Packard. Samsung has announced it too will offer Windows PCs based on ARM. He added that Cortex-A76 SoCs implemented in 7nm will allow licenses to achieve clock frequencies in excess of 3.3GHz while consuming about half the power of available mass-market x86 processors.
“The CPU roadmap ARM has laid out coupled with Qualcomm’s heterogenous approach to computing across our various IP block and integrated connectivity, will allow for new advancements in the always-on, always-connected PC experience offered by the Qualcomm Snapdragon Mobile Compute Platform,” said Alex Katouzian, general manager for mobile at Qualcomm Technologies Inc., in a statement issued by ARM.
