Intel procesoriai lėtės??

[Matas Alekna]

Manau angliškai visi suprantat tai.. Ką gi, reikės prie ryzen pereit ;D

 

Intel chips have a massive design flaw, and both Microsoft and the Linux kernel developers are scrambling to fix it. The security hole can be patched, but the patches will make PCs (and Macs) with Intel chips slower.

We don’t know how much slowdown you’ll see yet, but one developer says a 5% slowdown will be fairly typical—at least on Linux—while certain tasks could experience slowdowns as high as 30%.

What’s Going On?

We don’t know the exact security flaw yet, as it hasn’t been publicly revealed. But we can deduce much of what’s going on from the changes being made in the Linux kernel, where development happens publicly. Microsoft is also making similar changes to Windows, which are currently active in Insider Preview builds. Apple will be forced to make similar changes to macOS, as this is a flaw in Intel CPUs.

What is the Linux Kernel and What Does It Do?

 

Programs running on your computer run with different levels of security permissions. The operating system kernel—the Windows kernel or the Linux kernel, for example—has the highest level of permissions because it runs the show. Desktop programs have fewer permissions and the kernel restricts what they can do. The kernel uses the processor’s hardware features to help enforce some of these restrictions, because it’s faster to do it with hardware than software.

But Intel messed up somewhere, and the hardware that was enforcing these restrictions apparently doesn’t always work properly. So, to ensure that programs with fewer permissions can’t sneak into places they don’t belong and see things they shouldn’t, the restrictions will need to be strengthened in software (through the aforementioned patches).

So, in a worst case scenario, JavaScript code running in your web browser could reach down into the kernel and access things it shouldn’t. The fix being put into place means it won’t be able to escape its restrictions. Unfortunately, putting these extra checks into place means some operations are now slower.

AMD hardware is not affected. This change (and possible slowdown) only affects systems with Intel chips.

If you’re interested the lower level details, you should read this longer deep dive by The Register. But we won’t know the full technical details until the embargo is lifted.

How Much Slower Will My PC Be?

We don’t know how much this will affect day-to-day PC use yet. Dave Hansen, a Linux kernel developer who works at Intel, wrote that the changes being made in the Linux kernel will affect everything. According to him, most workloads are seeing a single digit slowdown, with a roughly 5% slowdown being typical. The worst case scenario was a 30% slowdown on a networking test, though, so it varies from task to task. The fix slows down system calls, so tasks with a lot of system calls, such as compiling software and running virtual machines, will likely slow down the most. But every piece of software uses some system calls.

These are numbers for Linux, so they may not apply to Windows at all. The changes being made to Windows may be different, and we may see less (or more) of a performance hit. How much this will actually end up noticeable in normal day-to-day computer use is still unclear.

We really don’t know what’s going to happen, and we won’t until the embargo is lifted and people have time to benchmark the updated versions of Windows.

But one thing is clear: Your computer is definitely not getting any faster with this patch. If you have an Intel CPU, it can only get slower.

When Will the Patch Affect My PC?

The Register expects Microsoft to publicly release this patch on the next Patch Tuesday, which is January 9, 2018. The changes will appear in an upcoming version of the Linux kernel, and we’d also expect Apple to patch macOS with similar changes fairly soon.

While a performance hit sounds bad, we strongly recommend installing these patches anyway. Operating system developers wouldn’t be making such massive changes unless this was a very bad bug with serious consequences.

rip intel? nes, dabar kaip turiu intel tai viskas ok prie ryzen'o labai brangiai jis kainuoja jau geriau amd.

[Estas]

Kas dar angliškai nesuprantat yra taip pat viskas parašyta apie tai tik lietuviškai.. žodžiu nieko gero čia su tuo intel

[Tautedorus]

Bus įdomu pamatyti benchmark'us po patch'ų. Jei iš tiesų performansas kris ne keliais, bet dešimtimis procentų, bus labai nesmagu, ypač naudojantis laptopu su gan silpnu procesoriumi, kuris ir taip vos susitvarko .

Intel akcijos turėtų pakristi, o amd pirkimai išaugti.

lietuvoje vien uz branda asus-varles "legenda" tapusi nesamone ar intel kaip cpu developeri/manufactureri nepakis isviso xDD na ligi tol kol prikejai prades prekybininku puslapiuose pizdierinti apie sitai ir teks jas musti, nes juo preke populiaresne ar labai isreklamuojama juo maziau support'o jie jai skiria

tas pats ir su prebuilts bus. manau zmones privalo patys imti dometis kas ir kaip nes daug kas nes i garantini neturedami zalio supratimo kodel sistema eme leteti  zenkliai.

man labiausiai idomu kiek paprastu zmoniu perskaitys sia tema is supras kas ten rasoma :))

 

@Rockstar matau jau 15min.lt komentavai

Štai gana informatyvus vaizdo įrašas su keliais benchmark'ais:

Gausim persimesti ant AMD ryzen, šiaip ištikro būtų vertą ryzen seriją išbandyt

Pasirodo yra ne viena, o dvi spragos moderniuose CPU. Taip, galimai kita spraga yra ne tik Intel, bet ir kituose procesoriuose. Šios spragos pavadintos Meltdown ir Spectre vardais. Apie šias spragas ir apie OS saugumą plačiau skaitykite TechSpot straipsnyje.

Na, gamer'iams šios spragos fix'inimas neturėtų kelti problemų :

 

[urnezo]

Niekas nekris, kainos ir pns, gryna ziniu manipuliacija, pilnai neisiskaitot kaikurie ir panikuojat, oi, reikia keisti processoriu ir pns  nieko nereikes keisti, gameriai, namu vartotojai net nepajus jokio skirtumo  kentet gali tik visokie "services" kaip cloud, google, ir pns. Kainos gali kristi nebent senesnes kartos procesoriams, kuo stipresnis procesorius, tuo maziau kris. P.s del klaidu man *Myliu SuperGames.lt*, tyngiu dbr eit i control paneli ir detis ta lt kalba.

Kaip ilgalaikiui AMD useriui man juokinga kaip dauguma čia pergyvena ir ruošiasi bėgt prie Ryzen. Sėkmės jum neprarandant performanso su xujovais AMD draiveriais ir prastom optimizacijom iš programų pusės... Ypač jei ruošiatės kažką daugiau veikt, nei tik geimint... Nors ir iš geiminimo pusės tai liečia, kai emuliaturiai dažnai kelis kartus geriau ant Intel veikia...

kaip intel useris, tu rinktumeisi g4560/g4600 su b250/h110 mobo ar ryzen 3 1200 entry rig;ui kad nereiktu imti obsolete'inta socketa?

price to performance low end/budget sistemai siuo metu amd geriau ir tai faktas, kadangi nera h370 h310 pigesniu mobo... ir manau ne kiekvienas isgali 100~euru isleisti pigiausiai z370 micro atx pagr plokstei 500-600euru biudzete.

polaris ir ryzen buvo siprus zingsnis amd i prieki kai vega atgal, del prastos optimizacijos zaidimuose nors del miningo tikrai ne.

ir nesakyk kad intel neturi isvis problemu, kur ju kreivos bios ir 14nm technologija del temp spikes/earlier thermal throttle su ~70C thermal margin'ais kai ta fixing delid+ bios update.
