MerolaC:

Not to burst your bubble, but... AFAIK, yours is also affected with IME bugs, and Spectre and Meltdown too.

I tought IME bug only applied to 6 gen and above. Sadly yes these new ones affect but atleast windows patch doesn’t make witcher 3 10% slower 😉

dragonlord:

I am testing older (back to 2006 under Win 10) as well as the newer processors and I'm only seeing 1-2% at worst...which I have always assumed is within the margin of error for new OS and driver upgrades anyway.

No point for testing older hardware i.e. CPU's without new CPU microcodes beeing released, updated microcodes needed to mitigate Meltdown and Spectre security flaws.

kruno:

They didn't test old machines, as i have noticed plenty of people here on forum have "old" 2000 or 3000 series cpu's. Edit: That is one of more interesting stuff to test and that is the thing Intel is in unique position to test, of course i am not forgetting that they didn't post results for even older systems, and god knows there are plenty of Core2 CPU's in use

That's because old machines don't get microcode updates... no love for 2000 and 3000 series CPUs. But I'm surprised that obviously you missed all that, since those news are circulating for a week now...

The windows patch does next to nothing different. But without a mikrocode update you're still vulvernable for all but one of those attack routes, more or less rendering it useless.

This.

I've heard the speculation Intel tested only Skylake and upwards because migitations cost far less on Skylake and newer than on Haswell and lower, so this test will only be another marketing BS from Intel. That's just what I heard, not my opinion. If my Pentium II 350 could run Win10, I would give it a try and post results, but I cannot find compatible drivers for my ASUS P2B-F. The "newest" OS available to choose from is "Win9x". 🙂

Honestly I would like to see Sandy and Ivy to get updated microcodes. Those CPUs and systems they're running really deserves few more years of healthy life. 2600K/2700K/3770K OCed @ 4.4GHz and up are still one helluva beasty CPUs, hell even i5 Sandy and i5 Ivy are still powerful CPUs OCed to 4.5GHz and higher but they're showing their age now with more CPU demanding multithreaded optimised games and apps, it's a playground where HT advantage of i7 Sandy and Ivy now really makes them worthy for those who invested a bit more cash back in 2011 and 2012 buying higher priced i7 Sandy or Ivy istead of i5 Sandy or Ivy. Also it's a bit on a weird side that Intel didn't released updated microcodes for lets say Sandy 2600K for few years now but older CPUs like for example Werstmere based Xeon X5670 has a newer microcode (both still without Meltdown/Spectre-proof updated microcodes tho) compared to Sandy. 2600K introduced back in January 2011 latest microcode dates back in 2013 but older Xeon X5670 introduced back in March 2010 latest microcode dates back in 2015. Guess Inrtel thinks something like: if ain't broken - don't fix it... I'm almost sure nothing below LGA1155 would get updated microcodes to mitigate Meltdown/Spectre security flaw this time. 2000 and 3000 series Sandy and Ivy: even for those chances are slim, lots af these are still in use nowadays and guess many Intel Sandy/Ivy users will be pissed if Intel doesn't invest some time to fix and release new microcodes for these. I would like to be wrong this time but guess no love for 1366 and 1156 series CPU's in form of updated microcodes for these. I still own few 1366 rigs, mostly Xeon X5670-X5675 based and OCed to 4.4GHz HT and higher, packed with PCIE SATA3 & USB3.0 cards, SSDs and beefy GPUs those things still kick ass in everything that's been thrown in front of them. Intel, if you read this (lol) make me regret for those hopeless statements above and release updated microcodes for Sandy, Ivy, Westmere, Nehalem...

Yeah, i know that, but like the others on the forum already mentioned, that machines are still pretty powerful, they can still be used without a problem in daily tasks, we are still years away from the point where 4c/8t Sandy Bridge is obsolete.

Just do a 200Mhz over clock and call it a day.

So in other words to cut it short: Performance is not compromised if the microcode is not updated as well? Windows update alone, without cpu microcode update will not compromise performance??

Indeed,in the wild tests I see better performance with windows patched without cpu microcodes.But depends of the tasks you use daily.In gaming the perf is not drastically changed.

Well there is update to the Intel saga,more bad news better to wait a little bit before applying Intel CPU patch Link : https://overclock3d.net/news/cpu_ma...boot_issues_after_security_firmware_updates/1

Yep, unsure of what to do now: no issues with performance loss tbh, but if my system would randomly reboot it would be rendered inusable for many tasks in the professional area, as well as gaming in many cases like online coop or competitive play. Honestly, I prefer a hackable system to one I can't use.
