Tasty looking new AMD chips!!!!!


I'm hanging for some confirmation re: virtualisation support and performance, but assuming its all gravy this is looking like the perfect workstation / homelab virt whitebox chip (affordable 8 core, mmmmm)

Don't call it a comeback!

Looks good, looking more like intel now.

DDR4 support,
hyperthreaded 8-core (16 threads)
3.6GHz with turbo to 4.0GHz standard,
unlocked multiplier so you can overclock the CPU clock only without messing up your ram clock etc
Decent amount of CPU cache - 4M L2 and 16M L3 but I wonder how this is shared across the 8 cores
14nm die
Other stuff included... like double AES for encryption on the die

I have been an AMD fanboy for a while, mainly because of the price point. I still have my AM3 system clocked to 3.8GHz. What I'm seeing of late is that it's really not about CPU clock speed, it's about threads and how much STUFF you can fit on a die. I like it.

Purple screen in esxi but works in Linux using bleeding edge kernels

...I don't follow

Doesn't work for esxi
Purple = blue screen

[Dieselboy]

Oh is it known that these chips dont support esxi? I can see that it could also be motherboard related.

Vmware in my opinion is very picky about new drivers or devices. Also there are lot of bugs they never fix from release to release. 6.0 brought enhancement but made it such complicated craps product. Just dealing with login was project of its own.

Servethehome confirmed with testing. No official stance from VMware so far.

Article handily confirms linux (including KvM) compatibility.

I'm toying with the idea to build a linux whitebox for KvM lulz but my sensible side is telling me to wait for others to hit all the inevitable compatibility/driver roadblocks first, plus there's absolutely nothing wrong with my regular lab boxes except not having a native linux box (then again anything I do in nested KvM is labbing so why do I care about whether or not its as fast as 'real' virt?)

I'm still using red hat virtualisation. Have you tried the latest ovirt? Version 4 is miles better than the 3.x versions I was using. I hated versions 3.x, kinda like 4.x though. If you look into setting it up I'll give you a hand if you need.

I've had that login problem with all my ESX boxes  Active Directory auth. new problem almost every time
