When you combine everything, motherboard & extra power consumption costs. They become quite expensive. I can get an H81/B85 1150 mobo for ~$30. Some E3 Xeon 8T can be negotiated for ~$190. With idle power consumption of roughly 20-30W, load at 90W max. That's cheap (speaking from 24/7/365 operation). The raw performance difference between 16T SB and 8T HSW (when you lock Turbo to all cores) isn't staggering, unfortunately.
Agreed.
That's true, however if you want to build something today, Haswell E3s and SB E5s are the most affordable. If you are serious about MT performance, this board coupled with a pair of E5's should make performance per $ quite reasonable. But if you can get a cheap X79 board, then it could be an option as well. I just don't like the excessive power consumption of the X79 series for usage in the less MT'ed scenarios (it can consume up to 2-3 times more than 1150 at lower loads), granted it has been improved since the X58 days, but I hate that you still need a dgpu for that (unlike server boards). So for me it's easy, either a proper dual SuperMicro board or some cheap 1150 w/ E3.
Everything stock, except the E3 Xeon is locked at Turbo. I just picked the E5 results (one of the highest to make sure it's represented well here). Windows 10 Pro x64. The E3/i7 both turbo at 3.7 on all cores so they fared more or less as expected.
Piledriver has ALWAYS been an option, they are just less attractive due to worse performance per watt and higher idle consumption. But if the price is right, and your workload can take advantage of its architecture, then it is also a viable option. If you spot a good combo deal on them, please come forward.
Mostly, because I already own the 1045T. But it could be fun to mess with an 8320E, if it were cheap enough. ($100 or less.)
Compared to the 1150/1151 platforms it's relatively high. Depending on your motherboard choice and power supply, you can have it anywhere from ~15w (MSI ECO range) to ~30w (some "lousy" ASrock design), using just the integrated graphics and some solid state drive. The platform Piledriver has to use is outdated and not power-efficient by todays standard. But of course, compared to the X79/X58s, it looks much better, as you have duly noted. AMD could have easily fixed that, but it looks as if they abandoned the AM3+ platform all together, giving the castrated designs, i.e. FM(x) the upper hand.
Yep, making it even less power-efficient.
My old Thuban system idled around 33-35 watts w/ integrated motherboard graphics (HD 4200). It had one of the most power-efficient board on the market at that time along with a very low power Hitachi 2.5" 5K500.B mobile drive. Some regular Seasonic 330W PSU, I believe. And God, I believe it was undervolted some (think I shaved off another 5W from idle power consumption by doing that). Heh.
Please do, when you get a chance.
Makes sense, yeah. Thanks for point this out. Maaan, there are so many of them. And not that expensive considering the firepower they can have.
Exactly, this is cheaper than an i3. Really, no better alternative if you require affordable MT performance. 577 and counting! Amazing deal. So, are you in for some action?
Appreciate your response, man. I mean it. Ordered a couple for testing, already! Thanks.
What board do you have? Does this feature require BIOS support of some sort? Wish it could read the temp from BIOS and act accordingly.
