So apparently there’s a new round of exploits/bugs out that effectively renders hyperthreading insecure or useless in some contexts. https://marc.info/?l=openbsd-tech&m=153504937925732&w=2 quote:Two recently disclosed hardware bugs affected Intel cpus: Can someone smarter than me tell me if this is as bad as it sounds?

Immediately: nah. It will likely take months to years to develop this in to a toolchain to effectively dump the contents of memory from a non-privileged process.

k-uno posted:Hey, quick follow-up question: if I set up a workstation to run virtual machines, is it possible to assign one entire VM to each socket? E.g. if I have a two-socket system and run two instances of Windows 10 simultaneously using VMs, can I have one copy use CPU A and one use CPU B? Doing things this way would get around a maximum core count limitation in the software I'm running, as well. If so, which would be the right VM software to use? Hyper-V? VMware workstation? VMware esxi would be best. Workstation can do it too but in my experience it has problems hanging. Google "cpu affinity" for whatever hypervisor you're using. Note that you really don't want to do this except to get around oracle licensing (which is the only reason the feature exists). The hypervisor needs some overhead beyond the vm workload to schedule the vcpu, so locking it to one core means the hypervisor has to halt the vm periodically to do housekeeping. Hypervisors and host operating systems are way better at scheduling than you are; license agreements are generally the only reason to do this.

My motherboard is solidly on the way out (stalling at 99 post code probably 40% of the time, and for some reason my audio playback is popping and catching no matter what DAC I used). Whats the current best guess for 9900K Z390 release? I really need an upgrade.

Globalfoundries is giving up on 7nm and beyond. Looks like AMD is moving to TSMC.

A 9700K build would be really tempting but I'm going to try to wait until AMD releases Zen 2 before deciding whether to go with Intel or AMD next time around. I want my next CPU to have as much longevity for gaming as my current i5-2500K is having.

Clearly, the correct answer then is to get a 9900K and disable hyperthreading

4,7 GHz on all 8 Cores of the 9900 K without OC seem nice and perfect for my next Build. While Games might not profit from the 8 cores and 16 HT (yet), it should be an amazing engine for World of Warcraft Multiboxing with 8 chars (WoW demands 1 native core per instance as best scenario) and I don‘t have to buy the more expensive (and per-CPU-quite-slower clockspeeds) i9 CPUs with 10 or 12 or 14 cores . 🤔 Mr.PayDay fucked around with this message at 21:19 on Aug 28, 2018 |

Whiskey Lake and Amber Lake CPUs were formally launched today. Both are actually still Kaby Lake Refresh underneath, with new names connected to the new PCH with the same features on Intels new deskop chipsets: USB3.1G2, integrated wifi, etc. They are in the "8th generation" for Intel's marketing scheme thats been broken by 10nm. Expect all the thin and light SKUs from everybody to be updated with these. https://www.anandtech.com/show/13275/intel-launches-whiskey-lake-amber-lake

mystes posted:I can see the appeal of a game where you control multiple characters simultaneously, but it just seems crazy to go to such lengths to simulate this by running multiple instances of a game where you control a single character. It's like a huge, ever evolving puzzle wherein you generate large quantities of salt via being in control of a hivemind of highly frontloaded DPS characters. Just being able to get it working in the first place is a huge sense of accomplishment for a lot of people.

You cant multibox in BG‘s since years as the /follow command was disabled in Cata IIRC. I use it for PVE and Farming and it is amazing and fun. The WoW Multiboxing communities are growing ( I have over 70 Multiboxing people in my Discord) since many months since you can loot ore nodes and flowers with 10 chars. Killing rare /special mobs allows looting with each char. If you warnt to pay for all chars (if even needed, usually Multiboxing pays for itself because of the „loot performance“.) it is just a different approach to experience of the WoW. Oh, and Multiboxing Fishing is a thing and a great Goldmaking Fundament of my portfolio of stuff I farm  Disadvantage: Entry cost (WoW license per char and monthly fee + IS Boxer fee and a somewhat potent system). Edit: hence my eyes on the 9900K as interesting CPU for 8 Boxing in WoW. Mr.PayDay fucked around with this message at 23:57 on Aug 28, 2018 |

Welp, that’s pretty much just a ongoing evolution in processors. Looks like we’re waiting until 2019-2020 for a real bump and I’m looking forward to the Gen. 10-12 IGP.

I think I just got my shipping notification for my 8086k competition; I got a mystery DPD delivery text that a package is on its way and I haven't ordered anything in weeks. I saw a reddit post where someone received theirs recently so it's the only thing I can think of.
