The ARM Cortex A73 – Artemis Unveiled

They're also unveiling their new GPU architecture, Bifrost, that uses that same sort of SIMT structure that desktop cards have used for a few years with memory coherence with the application processors.

Yes this is the really interesting review imo :)

The wavefront divergence problem is really calling out for a Mill-style NotAResult flag for speculation etc so it can get more pipelines per thread again ;)

I haven't even seen anywhere to buy the A72 even though that was announced around a year and a half ago.

The biggest reason for that is that Apple, Qualcomm, and Samsung have designed their own custom cores, rather than using ARM's license-able ones. So most of the phones you see, instead of using Cortex A72, use Snapdragon 820 or Exynos M1. (Huawei's Kirin 950 uses A72 cores, though.)

One of the more interesting bits about the A73 announcement is that they're offering a new licensing level for SoC makers to customize their cores starting from an A73 base, and that Qualcomm has taken that license; so the next-gen Qualcomm SoC won't have the A73 name, but may have a lot of its tech.

Didn't know Samsung had picked up an ARM ISA license.

Unlike, say, AMD, Intel or Apple, ARM does not make or market CPUs to consumers. They design and market CPU IP to SOC makers. The road from inception to actual product for a typical SOC is longer than a year, and from that it takes time for device manufacturers to actually put the SOCs into devices and sell them to you.

This naturally means that it takes quite a lot of time for ARM cores to go from the time you first hear about them (when they are being marketed to SOC makers) to being as close to release as the point when you typically hear about other CPU cores (when they are being marketed to you).

You can always buy an Amazon Fire TV and root it (A72/A53 combo - https://developer.amazon.com/public/solutions/devices/fire-t...)....Qualcomm has an 810 dev board you can hack on( https://developer.qualcomm.com/hardware/dragonboard-810). ARM also offers a dev board system (http://www.arm.com/products/tools/development-boards/versati...). I suspect there are dozens more, you just have to look a bit (and decipher marketing literature to figure out which ones are 72's).

Huawei mate 8 got it.

Also: Huawei P9 (+ plus), Sony Xperia X, Alcatel Idol 4S. Samsung Galaxy Tab S2, Amazon FireTV 2nd gen and some still unavailable smartphones.

It takes a while to go from announcement to devices with the core on store shelves.

Especially with ARM being an IP vendor. There's usually a 2 year period between new core announcement and shipping, although this time it may be a little shorter.

Is there a mirror of this anywhere? All I am getting is "Server Error in '/' Application."

I'd really love to see some very high clock speed arm processors even at the sacrifice of less cores. A lot of the work were doing with interpreted languages these days bottlenecks on a single threads maximum performance on one core often due to the complexities around avoiding the GIL inefficiencies in Python, a RISC processor with a high clock speed could be a really interesting match for such processing.

Could have sworn there was a couple of companies looking into that for server usage a few years back.
