Is the newer gear much better? Or has FB merely decided to change hardware strategy?
Is the newer gear much better? Or has FB merely decided to change hardware strategy?
Luckily for us and other hardware enthusiasts, the TCO is still fine because the alternative is a $685 E5-2630v3. The 30W TDP difference isn't enough to offset that price:In overall performance? No, the newer stuff doesn't perform extremely differently. But, when you own and run hundreds of thousands of CPUs, overall performance isn't what you care the most about. Large companies such as Google care much more about efficiency, where both Haswell and Broadwell Xeons destroy the Sandylake Xeons, that they have replaced.
Even if the total purchase price is 30-40% higher, the TCO (total cost of ownership) becomes much, much lower if doing the same amount of work only uses let's say 60-70% as much power, since it will be multiplied by however many hundreds of thousands of CPUs you're running.

(Assuming a 5 year lifespan and a $0.11 per Kwh charge for electricity):
43800*0.03*0.11=$144.54.
Running it flat out for the whole 5 years, the 30W difference isn't enough to bridge the gap. Heh.
EDIT: WOW. Intel really has an ace in the hole with the Xeon D.

You forgot the fact that if ou run a datacenter with thousands of these cpus you need to cool it. And the cost saved on cooling adds up quickly.
AFAIK there are plans (or already built by now, don't really know) for datacenters which use the generated heat for heating houses in winter.
Holy crap!! That is a steal!! Thats like someone giving away a lamborghini for $1000 bucks. Are these real or are these ES cpu's? I got scammed once already trying to buy a pair of e5-2650's and they turned out to be fake ES cpu's that didnt even work.Had to file a claim and everything just to get my money back . cant go wrong if these are legit and only $70.00 bucks. I dont even give a crap about overclocking I just need more cores for video editing/encoding and rendering.. What do you guys think should I grab a couple of these puppies??
With that mentioned, I do wish there were some new low cost X79 boards as well. (E5 2670 would make a good entry level gamer)
2.6GHz Sandy Bridge? Eh, not going to be that great for gaming, especially with the price of the motherboard. Single thread performance just isn't going to be that good. Better off getting a Haswell i3.
Newer games are scaling better with eight cores so I would rather have one of these than Core i3.
For older games I would take i3 though.
Ah, the old Bulldozer argument I can see your point, but I suspect plenty of lower budget games will have single-thread bottlenecks. Nothing like a single high-clocked core for ploughing through lazy coding
There are plenty of games out today that show limitations below 60fps on high clocked (4.5ghz+) Sandy Bridge. I expect that, despite the absurd amount of threads, you'll feel the limitations in IPC pretty frequently.
Note that at these clocks, the per-thread performance is lower than an overclocked Piledriver CPU.
