Nothing but nothing will make me change my mind for this years upgrade!
Kaarme
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!
HardwareCaps
These things are set years back. will just get another BIOS & OS update.
Undying
AMD wins again.

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

Amd is imune to low latency and high memoryspeed too 😛

Accidentally, I am sure.

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.
Kaarme
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?
schmidtbag
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.
Kaarme
The governmental announcement says it like this:
I interpreted that as Xeon CPUs and the Intel Xe GPUs.
schmidtbag
I didn't see that part (I didn't know Optane was being used either). So yes, it does seem both Xeon CPU and GPU are in use. But like I said, the CPUs probably aren't doing the heavy lifting.
HardwareCaps
Huh? Spectre was also a hardware flaw, you can just work around it with software.... not ideal but viable for sure....
chispy
Oh dear , it makes me feel happy and more secure online using my Ryzen 2700x 24/7 pc 😀. My 9980xe , 9900k and other Intel cpus are for benching purposes only 😛
nizzen
I use Cyrix cpu offline, for maximum security 😀
Nobody really care about "the security flaws" in cpu's.. That is an fact 😉 What most people care about is performance...
chispy
Not a fact , fiction on your mind , i do care about security as well as many others , now tell me your source as a fact that most people care more about performance than security , prove/link/sources please 😉 or you are talking out of your ass lol
illrigger
Yeah, "not ideal" barely scratches the surface on that. Meltdown was more severe, but the fixes were done in the first 6 months. The aptly-named Spectre still continues to haunt us.
If you work in the corporate world, you know that that fix was a long, difficult process that caused a lot of downtime and left everyone vulnerable for months, even AFTER the fix was first made available. There have been multiple variants on Spectre and pretty much every monthly patch cycle still has some notes saying it fixes something related to it across every OS, and this is a full year later.
