AMD Threadripper 2950X versus i9 line?

[Kayley]

Nah isboxer doesn't manage the affinity well and I don't expect it to now that I've had a pretty good look into it. You can google the AMD CCX and AMD windows scheduling conflicts and make your own opinion on whose fault is whose. I use a program that was recommended to me; 'Process Lasso'. It enables me to do BULK affinity swaps with a click of a couple of buttons-- very handy. It also balances the load a bit better than default windows and i'm able to specifically target a processor group quickly/easily.

The romance phase has ended-- while the 2950x is powerful as heck-- it has it's drawbacks.
So you can see the CCX (Die packages / processor groups) here. I'm using a 2950x as a demonstration, it has two CCX cores.
If I max out either CCX core it will lag the hell out of your windows OS-- the games run amazing, but doing anything from windows is sluggish. It's best shown with this. The little red dips are when the system is struggling to understand what is going on and the cursor (in windows) has micro-stuttering. All I did for this to happen was to put an unrealistic load on one die package. I left one die package, 8 cores FREE yet windows was still trying to move things around and involve the secondary processor group which was being stomped by my mboxing clients.

In order for this to happen you really do have to overwork the CPU. It took me 45 clients in a busy area smashing on a turnip (number calculations) to create this type of scenario-- but it exists. When I did my 85+ client test I didn't care that the OS was a bit sluggish as I expected that.

Linux doesn't suffer from these problems as the kernel handles the i/o operations better-- for whatever reason the Windows kernel doesn't.

So if you are going to 20-box, pvp, high traffic areas etc-- This CPU can handle that and it's better than anything intel has in the same price range.
However if you are gonna run 30+ accounts, have youtube up, stream, bitcoin mine, just thrash your CPU with monster computational demands... you wont like the OS experience.

This was my concern. I don't like hassles. I'd rather pay a little more and not have to screw around with extra programs and micromanaging stuff that should just work out of the box.
