Princeton University researchers presented a 25-core "manycore" CPU at the Hot Chips conference:

It was a week for chip launches with the Hot Chips conference setting the stage for the unveiling of the IBM Power9 processor (report forthcoming) and a custom ARM-based 64-core CPU from Chinese firm Phytium Technology. A 25-core academic manycore processor out of Princeton University also made its debut from the Silicon Valley event.

[...] "With Piton, we really sat down and rethought computer architecture in order to build a chip specifically for data centers and the cloud," said David Wentzlaff, a Princeton assistant professor of electrical engineering and associated faculty in the Department of Computer Science in an official announcement. "The chip we've made is among the largest chips ever built in academia and it shows how servers could run far more efficiently and cheaply."

Piton is based on the SPARC V9 64-bit ISA and supports Debian Linux. After being designed in early 2015, Piton was taped-out in IBM's 32nm SOI process. The 6×6 millimeter die has more than 460 million transistors. The silicon has been tested in the lab and is working, according to the research team.

The design is open source (open, DOI: 10.1145/2954679.2872414) (DX). More information here.

    Unless you go back in time and get older versions of NT that supported other architectures like MIPS and Alpha.

    And of course win 10 will run on ARM.

    Do you have that running?
    ...or are you repeating scuttlebutt you've heard?

    My sources [google.com] say it's still vaporware.

    There is no equivalent to Windows RT [wikipedia.org] for Windows 10, and Microsoft does not consider Windows RT devices to be compatible with Windows 10.

    Windows 10 Mobile, based on Windows Phone, was unveiled for use on tablets and smartphones with ARM architecture.

      I was close to modding you up, but I checked Wikipedia's references:

      The evolved Windows Phone, which is designed for both ARM and x86-based processors, and which runs on devices with 8-inch or smaller touch screens, runs one set of apps. The evolved Windows 8.1, which runs only on x86 processors and has a non-touchscreen mode, runs another set of apps. But Microsoft is giving them the same name.
