Links to descriptions of similar vulnerabilities in AMD and ARM processors would be very welcome.

Here's a list of what google tested:

Intel(R) Xeon(R) CPU E5-1650 v3 @ 3.50GHz (called "Intel Haswell Xeon CPU" in the rest of this document)

AMD FX(tm)-8320 Eight-Core Processor (called "AMD FX CPU" in the rest of this document)

AMD PRO A8-9600 R7, 10 COMPUTE CORES 4C+6G (called "AMD PRO CPU" in the rest of this document)

An ARM Cortex A57 core of a Google Nexus 5x phone [6] (called "ARM Cortex A57" in the rest of this document)

So there's a bit of an unknown if AMD's most recent generation of processor has the Spectre vulnerability?

We know that the scariest attack "meltdown", cannot be reproduced on AMD or ARM chips at all[1]. The second attack "Spectre" is also greatly mitigated due the neural network predicting pathways for the application. Thus it's unlikely/less-likely that you'll be able to access other locations in memory[2]. However, it's definitely possible.

ARM advisory [1] does state that Cortex-A75 is vulnerable to variant 3 (Meltdown).

Has anyone tried the Spectre PoC in the paper on ThreadRipper? I can confirm it works on my i7-7700K.
