moin moin,
Interesting - I would guess that is due to how Intel mimics UMA on
what is basically a NUMA platform. If your application is multi
threaded and those threads share one large memory space and the
application does not keep NUMA in mind intel will have you paging in
and out of the cores allocation - if enough ram is use perhaps even
forcing to swap to achieve this. BUT on the other hand it does offer
the flexibility that true NUMA does not. I would love to see a head
to head when 1 app uses ~95% of the ram and has more then 2xCore
threads.
If I have time, I'll open /dev/sda in emacs :). Dunno if vim can
multi-thread well enough for that type of test.
The goal is to not max out RAM or anything else for a couple of years for
this box.
In my case, the worst I'll have is a private MySQL database where the
entire contents of of the database wouldn't fill up a single stick of RAM.
I will have other things running as well, but all comparatively
lightweight compared to something that could keep two cores and 95% of the
RAM busy.
ciao,

So far the AMD solution is 8 cores not 4. and AMd seems to be doing better
in Ram performance heavy applications. other than that the Intel is doing
better.
that being said I have been getting a great experience from my hex core
1090T and the price difference seems to be well worth it.

moin moin,
need to get a new desktop. But, since it's me, it'll have external storage
and other things that are abnormal today :).
Currently comparing two boxen with 4 core, 8 thread CPUs. One is the AMD
FX-8350, the other is the intel i7-4820k. Any opinions on how they
compare?
