AMD Confirms that Ryzen CPUs are Immune to SPOILER Exploit
Two weeks ago new vulnerabilities for Intel procs surfaced. The vulnerability was given the name Spoiler and was discovered by the Worcester Polytechnic Institute and the University of Lübeck. It involves a leak in page mapping of working memory, making other attacks much easier to perform.
Intel has was notified of the problem on December 1st. According to the researchers, a solution via a software update is virtually impossible and can only be remedied with an adjustment in architecture. If this is done, it will undoubtedly lead to lower performance. Whether there is a solution is very doubtful. Arm and AMD processors are not vulnerable to this attack, however they never confirmed that.
AMD has since responded officially and confirms that their Ryzen CPUs are immune from the threat.
We are aware of the report of a new security exploit called SPOILER which can gain access to partial address information during load operations. We believe that our products are not susceptible to this issue because of our unique processor architecture. The SPOILER exploit can gain access to partial address information above address bit 11 during load operations. We believe that our products are not susceptible to this issue because AMD processors do not use partial address matches above address bit 11 when resolving load conflicts.

It also didn't make the US Department of Energy change their mind about a new supercomputer based on Intel processors, priced $500 million.

Like I said again and again , time to sell that INTEL stock. Every freaking tech announcement from Nvidia and Intel keeps making AMD look better and better!

These things are set years back. will just get another BIOS & OS update.

Curiously, if you rearrange the letters of Intel, you can get 'let in'.
Coincidence? o_O

But if you fix ALL of these exploits, I bet Intel is on par if not worse compared to AMD.
Get lost.

Isn't that based largely on Intel's new server GPUs? That's kinda comparing apples to oranges.

It was already mentioned in SPOILER original document, that you cannot patch or fix it, because it is wrong on physical design level. Sure you can maybe use BIOS fw patch to not use that address space, but it will basically lop of 20-50% of CPUs performance. So basically Intel got it's superior CPU speed over AMD by cheating with security.

Isn't it going to be a Xeon platform with a bunch of GPUs tied to each CPU?
Who cares about security when you get 10% or even more fps in games?

And Hep C...
Somehow that doesn't surprise me when the EPA had Pruitt blowin money on office shenanigans... Our government isn't known for many things prudent when it comes to cyber for the last decade.

I don't know what the CPUs will be, but the GPUs are also called Xeons; this isn't the first time Intel has done such a thing (Xeon Phi, for example).
In either case, I'm sure the CPUs function more as a medium to moderate the data rather than do any heavy calculations, so, their security isn't as much to concern over. That being said, Epyc would be a smarter choice for that purpose IMO (due to lower costs, better security, and more PCIe lanes), but, I'm not sure what it is they're using. They could be using POWER9 CPUs for all I know.

The governmental announcement says it like this:
These include a future generation of Intel® Xeon® Scalable processor, a future generation of Intel® Optane™ DC Persistent Memory, Intel’s Xe compute architecture and Intel’s One API software
I interpreted that as Xeon CPUs and the Intel Xe GPUs.
