I am looking to build my first unraid server, I am planning on using it to host VM's so virtualization is key. I plan to run AMD processor (price and number of cores) My question is looking at MB on the market today , which one do you recommend. I thought about getting a Asus M4A89GTD -- any thoughts?

 

 

thanks

I think the trend now to go with Intel CPUs. I just moved from a TriCore AMD to a Intel Core I5. I think the reason is they perform better and comsume less power.

My only issue with Intel CPU is cost  and I need to get 8 or more cores,  Does the I5 have 8 or more cores or threading?

 

thanks for the advice.

Keep in mind that AMD cores != Intel cores.

I would be more inclined to use benchmarks to choose a processor instead of core counts.

thank you -- I was not aware of the misleading information on AMD processors -- or alleged miss information.

It's not a simple matter, as you will learn as you do more research. There are tasks (and benchmarks) that favour AMD's approach, others are more suited to Intel.

 

The only blanket statement I feel comfortable making is that you will use less wattage per unit of work done with Intel.

my only issue with intel is the price to get 8 cores I have to pay more $$$$$ than with AMD. Has anyone using AMD seen any performance issues when using them for VMs?

No.

 

I run a FX6300 for VMs, and it runs really, really well.  It's a FX6300 on a M5A78 LE R2 board, and it has 32GB of DDR3-1600 ECC RAM.  It's quite power efficient all things considered, I've no real issues with the machine at all.

 

The FX8320E is a great chip for running a load of VMs on, too.

VM's will run okay on AMD, but don't get too focused on the number of cores -- look at the overall performance of the processor.    A low-end AMD 8-core CPU, e.g. an FX8320, is indeed very low cost, and has a reasonable amount of "horsepower" -- scoring 8024 on PassMark.    Note, however, that a quad-core Core i5 that doesn't cost much more than the FX comes very close in performance -- for < $200 you can get an i5-4590 that scores 7214 on PassMark (90% of the FX8320) ... and does that with a TDP of 84 watts -- well below the 120 watts the FX 8320 draws.  For a bit over $200 you can get i5's that do even better ... up to 7792 on a Skylake i5-6600k.    And if you step up to a Core i7, you'll get performance better than you can get on ANY of the 8-core AMDs, while still drawing far less power.

 

If you really want 8 cores, and don't mind a 125w CPU, there's currently a superb deal available on e-bay of some E5 series Xeon E5-2670's that were pulled out of data center usage => these are available in the $90 or less range, and score 12518 on PassMark (or over 18000 if you get 2 and use a dual CPU motherboard, as many folks are doing).    See this thread:

Even though these are first generation E5's, they still blow any AMD 8-core CPU out of the water ... and with the deals you can get on the CPU and registered RAM modules on e-bay you can build an amazing system for just a few hundred $$  (the biggest expense is a suitable motherboard).
