No but the IPC sucks compared to Intel.

Read the sticky. Sup Forums is not your tech support. You have three options. You can Google it, you can ask or you can fuck off.

yes, read the spectre article published by the people who found the bug
After much PR from AMD they admitted too

But it has 2x the cores/threads

I'm not asking for tech support you cum gargling goblin

There you go you cunt
now stop bumping this thread

nope ;)

No, friend, the Ryzen processor is not affected by the attack.

bump

Every single CPU on the market right now is affected by Spectre
Intel
AMD
ARM
Apple's

Meltdown is a different story

Yes and meltdown to but GayMD is paying load's too hush it

Any processor with out-of-order execution is affected by spectre, however, this is easily fixed

Meltdown affects almost all Intel processors and a couple of ARM processors and is much more severe and difficult to fix.

Meh, ARM-32 is not affected.
As well, as Intel Pentium MMX, and probably AMD K6 and K7.

Only to variant 1, and it was already fixed with minimal performance hit.

They are literally within 3-5%
Intel just has higher clock speeds retard

Yes to variant 1. Variant 2 on the other hand has not been demonstrated on any AMD processor yet and might be practically impossible to pull off due to differences in architecture, especially difficult it is going to be on Ryzen as it uses a learning algorithm in its branch predictor

op this a substrate level design feature its much deeper than patches and quickfixes

The benchmark is complied with intel’s ICC complier which optimizes complied code for intel processors and leaves out certain optimization’s for non-intel processors. By editing the vender ID on an AMD chip to an genuine intel it gives it a much higher synthetic score then the Default authentic AMD vender ID. This also causes some bugs (of course). Intel fan boy Reviewers (brainlets) don’t know nor care to understand the bias in the benchmarking programs and spew out how amazing intel is. The benchmarking program uses ICC for intel and for all others using GCC and C++ which is of course why Intel CPU's are "blowing" other CPU's in terms of performance and people don't understand how using ICC math complier library gives Intel a greatly unfair advantage

the feeling when the last secure CPU arch was the AMD FX lines

not really, the versions that are demo'ed require non default configurations on AMD to work and bios fixes have already been made awaiting the next AGESA update.

Variant 1 has been fixed, and patches are deploying.

Variant 2 hasn't been proven to work yet.

With the same performance as a hexacore.

>PR
No, Ryzen is 1/3 affected, Intel is 3/3s affected.

Meltdown can be resolved on an OS level. If the OS is breached it doesn't matter if you use intel or AMD.
This. Its is an ongoing issue based on speculation. Meltdown is clearly identified with a known fix (although some would consider it a difficult and inconvenient fix).

Every single 0.1 more matters for CPUs. More cores don't do anything for single-application use. All it does is improve multitasking of multi-application use. Single-applications get little use out of multicore unless the application relies on secondparty subset apps (ie second-party chat, browser, media player, anti-cheat, DRM, GUI overlay etc) which at best uses two to four cores.

Servers are a different issue but servers shouldn't be using consumer-level hardware in the first place.

is that a tool to check for vulnerabilities?
where can i get it?

Meltdown is probably the most severe, but it's fixable on an OS level.

The other two aren't, but, they're very, very hard to execute remotely and only one of them effects AMD.

Meltdown -> Affects Intel, not AMD.
Spectre on Intel -> Easily hackeable through Internet by a simple Javascript.
Spectre on AMD -> Direct Physical access is required to hack. You can not hack remotely.

Spectre have the same side effects on all processors

Also AMD

There are two variants of spectre fggot

Spectre would require physical access.

Will Zen 2 be Spectre-proof or delayed till it is?

>Meltdown is probably the most severe, but it's fixable on an OS level.

So if you pwn Minix you pwn the whole PC becaused you bypassed OS protection?

Dis gunna be good!

>muh meltdown

RIZON IS PLEBSHIT FOR NU-FAGS

EFNET BESTNET

Yeah, because it is a hexacore smart guy.

Zen2 yeah. Ryzen 2xxx is not Zen2
