Face of 30% - JUSTed

It's real, and it happened last month.

what's this about? i filtered meme vs meme threads but yours got through for not containing those meme words

Intel users are losing 30% of their performance due to a hardware bug

>30%
or more (63% on skylake)
Also any graphics cards that that use the CPU for scheduling are also daijoubu as this relies on kernel level access. Vega has it's own independent scheduler so, make of that what you will.

No need to panic. "30% perf decrease" is only when you do Virtualization. Do you play with VMS? well in that case you should be AMD anyway for the core/$ for local usage and for commercial usage you are probably intel vendor locked anyway so boo hoo, start living with it. Gaming, browsing, office, compiling won't see any impact.

That's not how this works. That's not how any of this works.

The 30% performance decrease is caused by added overhead in context switching. All major OSes maps kernel memory into the first GB of every single process' address space, in order to reduce cost of context switching, but is protected from userspace trying to read and write to it.

This weakness apparently makes it possible to leak this memory, which is why the Linux fix is to separate kernel memory in its own virtual address space rather than map it into the same process address space. This causes a significant overhead when context switching, as memory accesses in kernel space will now have to wait for memory pages to be faulted in.

This is where the 30% number comes from, PostgreSQL, an application that does a serious amount of IO and therefore needs to enter kernel space in order to set up and tear down DMA mappings, has a significant drop in performance.

My parents pc performance was already obliterated by the windows 10 update. Fug.

really?

duh.
It's a microcode patch which means it needs to be loaded at boot time and always remaining present so the kernel can interact with the unpatched CPU's firmware.

It's not that, but people were saying that normal users won't be affected that much. I guess you're parents are heavy on I/O.

I should sell my shitty laptop I guess.

AMD are completely uninvolved with this, baka.

did forbes give them this award for spending $300 million on marxist-feminist extortion organizations?

wow the tada 68 is pretty fire with zealios

>JUSTed

oh look another meme bandwagon to jump onto

>implying this "JUST" initiative is not corporate propaganda, and actually means jack shit in regard to how ethical a company is
you make me laugh, ameritards

>Selling an old computer
Smash it with a sledgehammer and run a magnet over what's left

>Was gonna buy gpd win 2
>It uses a very powerful intel mobile cpu
>Now it will be practically pointless with a 30% performance drop
