"Researchers uncover Spectre-like #Intel CPU vulnerability called #BranchScope"
Researchers from four US universities, College of William & Mary, University of California Riverside, Carnegie Mellon University in Qatar, and Binghamton University, have released a paper which details a new #Spectre like vulnerability that they are calling BranchScope, a new side-channel attack which targets the "directional branch predictor."

They have apparently tested it on Sandy Bridge, Haswell and Skylake processors,… See More

So overclock3d posted their performance review of #farcry5. Apparently in this game a Vega 56 is able to almost match the performance of a 1080 FE, possibly in part due to Rapid Packed Math support in the game.

If you don't know what Rapid Packed Math is here is a quote from the review that explains it:
"Rapid Packed Math allows AMD's Vega GPU architecture to offer a 2x performance boost when calculating FP16 math, giving developers the ability to accelerate specific workloads by using less precise… See More

So according to #AMD the vulnerabilities revealed by CTS labs are real and will be fixed via firmware patches and bios updates, they don't expect any performance impact, however they do mention that since admin access is already required to exploit these the unauthorized individual would already have the right to create, delete, or modify any file or folder on the system.

CTS-Labs an Israeli company created in 2017 has recently published a report about 13 vulnerabilities, technically 4 vulnerabilities with some variants. However they only gave #AMD 24 hours notice, from what I have read the standard notice is 90 days or more for hardware flaws, and had apparently already briefed analysts and the media before even notifying AMD so some people find this suspicious, and I am inclined to agree.

OK so it appears #Intel released a list of product lines vulnerable to Meltdown & Spectre, I missed it before because none of the articles I had read linked to it but I just found it on a comment on Anandtech.
So if you have an Intel CPU in any of the product lines listed in the attached picture you are vulnerable to Meltdown and/or Spectre, in the case of Intel you are vulnerable to both but in the case of AMD & ARM you are only vulnerable to Spectre.
