72 OoO cores, 4 threads/core (compared with current Xeon Phi's in order cores).
It'll even come as a regular socketed CPU (as well as PCIe addin card). Was
originally thinking about getting the 8-core Haswell-E. But now I might wait for
this instead!

The Haswell-E 8 core is a global 48GHz beast (at 3 GHz per core,
assuming HT is valuable as 1 core (my experience is rather 0,23 )), for
Q3/Q4 2014... at the usual $1000 price, usable on classical motherboard.
(well, rumors say that DDR4 is mandatory)


The Knight Landing... well, it's for later (best hope Q1 2015), and no
news yet about the socket, or the price.

That's my experience as well (Intel HT = 0.22-0.25 real core). Now $1000 price +
$$$ motherboard + $$$ DDR4. Might be a good idea to get an 8-core Sandy
Bridge/Ivy Bridge for < $1000. (eg saw a Xeon E5-2687W 3.1 GHz going for $650).

Waiting an extra quarter is fine. Price, on the other hand, hopefully won't be
too bad. Current Xeon Phis are anywhere from $800 to $1600 (ie don't pay more
than $1600 because the retailer is ripping you off beyond that).

Just because nobody complains does not mean all parachutes are perfect.

Probably more like "72 out of order cores" (as indicated by the OP's 
subsequent phrase in parentheses, "compared with current Xeon Phi's in 
order cores").

I just wonder what the hell those 72 cores are useful for if they're all 
defunct :-P

Yes, out of order. Their based on Silvermont cores, so they'll have much faster
single-thread performance than the P5-based cores now. Up to 288 threads! Need
to increase Povray's thread limit yet?
