I currently have a board with 2 x E5-2407 V2 in it. I'd like to upgrade to higher performing V2s, but the price is high too high right now. Maybe in another year. On the other hand the E5-2450L V1 is dirt cheap and I can pick up 2 for about what I can sell a single E5-2407 V2.
This would be for a virtual server that I'm leaning towards moving to FreeBSD and Bhyve.
The E5-2407 V2 is 2.4GHz with 4 cores, 4 threads, has 10MB SmartCache, a bus speed of 6.4GT/s, has a max memory bandwidth of 32GB/s, uses 80W and per the datasheet appears to be the same or very close to the the 2450L otherwise. 2 of these give me with 8 cores and 8 threads total and 160W of power usage. These 8 cores might be good for a workstation, but I wonder how much of an effect there is with a bunch of VMs.
The E5-2450L V1 is obviously a generation back, but it is 1.8GHz with Turbo to 2.3GHz, has 8 cores, 16 threads, 20MB Smart Cache, a bus speed of 8GT/s and uses 70W. 2 of these give me 16 cores, 32 threads and 140W of power usage. The base processor speed is lower, but with 4 times as many cores and threads, more cache and turbo to nearly 2407 V2 speed this seems more ideal for a virtual host.
Thoughts? Are there any big differences between the V1 and V2 processors that I'm overlooking? Unfortunately I already have the 1356 platform, I don't need that much power and switching isn't really in the budget.
What would you choose?
Thanks!
