1 CPU vs 2 CPU: Energy Consumption

[sqlagent]

Hello World

I am retiring my home hyper v server due to maximum memory limitations (Supermicro X7SBE only supports 8GB max). I have a Hyper V 2012 R2 environment that hosts 1 Domain Controller, 1 Domain Controller slash File Print Server, 1 SQL Server 2008R2 Data Warehouses for my trade data, 1 SQL Server 2008R2 slash ETL slash SSRS slash Application Server I wrote for weather forecasting. Due to my limit on memory everything ran slow when all 4 VM guest were running. I have a 5th VM guest that is a Windows XP machine for my t0rr3ntz, I always had to shut down another VM guest to run this one because of memory usage.

I am debating over upgrading to one Intel Xeon E5-2630 CPU or two Intel Xeon E5-2630 CPUs. The CPU's max TDP is 95 Watts. This is a stupid question but just to make sure my edumacated guess is correct, if I have two then that means my server will consume 190 Watts the majority of time CPU wise?

If I get 2x CPU then my mother board will be Supermicro X10DRL-i if its any helpful

Obligatory "TDP does not equal Watts used!"
But besides that, it would be 190 Watts TDP if both cpus were operating under max load - not the majority of the time (unless you run 100% most of the time).
It sounds like this would run 24/7, in which case I would guess it would idle the majority of the time. Check the idle TDP.

Intel states their TDP as the highest watts the maximum chip in a given family tree will consume under full load. This is so that their system partners (OEMs) can design effective cooling to deal with the heat generated by these chips. So, if you aren't looking at the top dog chip in the family, it should run lower watts than specified, as long as you haven't overclocked and/or overvolted it. And, remember, even if the TDP was perfectly accurate for your chip, that number doesn't cover the rest of the system.

Intel Xeon E5-2630 is going to be 2x or more powerful over anything you were running on the Supermicro X7SBE and more efficient and cooler.

One should handle all you mentioned above with no problem, But if you really thing you need 32 thread, Go for it.

I seriously doubt you're going to be running two cpus both at max TDP. Keep in mind that even just running all cores at 100% load wont necessarily push your TDP up to 95W. You have to be running heavy AVX code. Chances are that at full load on 2 CPUs the power will only be 130W, and from there you have to look at just how much time you're going to actually be spending at 100% load.

Yeah, bear in mind that it should clock down when idle.

So you're essentially doing nothing and you're taking up 8GB?
Try running one OS.
