AMD Ryzen Threadripper "Summit Ridge" Dies are Heavily Binned
AMD revealed that the pair of 8-core "Summit Ridge" dies that make up the Ryzen Threadripper multi-chip module are heavily binned. AMD hand-selects the top-5% highest performing "Summit Ridge" dies for Ryzen Threadripper manufacturing, which makes these chips of a higher grade than even what AMD sets aside for Ryzen 7-series socket AM4 chips.
AMD requires the highest grade "Summit Ridge" dies to use in Threadripper chips, to keep electrical leakage to the minimum, so the chips can run as cool as possible, with the least power-draw. Choosing the best dies could also ensure that Threadripper chips have the highest overclocking-headroom taking into account other electrical and thermal constraints. A 7-series chip such as the 1800X could still achieve higher clocks than a Threadripper chip, in that sense.

I think you mean "which makes their chips?"

I'm also pretty much on tenterhooks for the reviews. We've been waiting for this kind of competition for more than a decade now.
mighty time to build a new HEDT rig :D
We're still talking about a very tiny niche.
The reason why Intel seems to have given up on X299 is... they don't care. AMD can have the "PC Enthusiast" segment.
Now... the workstation segment is something entirely different. It will be interesting to see how Intel reacts with workstation-oriented Xeons.
BTW: does Threadripper have security features from Ryzen PRO? Because if not, ECC might not be enough to make it successful in business.
I think Intel will care about the gaming market, even a niche one as it's all about prestige and image, which helps to bring in the sales. Intel won't invest big money on bringing out a new platform they "don't care about", that's just silly. More likely they're not sure how to react to the Threadripper threat which is why we have these anomalies with Skylake-X and the next generation will be much better.
I've since read the review below linked to by Fluffmeister above which shows AMD caning Intel in productivity performance, so Intel very much has something to worry about there. This appears to be an official review too, so likely the others will be similar. Personally, I just wish that Ryzen's IPC was better than Intel's, which would then deliver an all-round killer product. The way things are going, that might actually happen one day.
How can you say for certain that AMD won't allow their CPUs to be unlocked? On what authority are you basing that on, or is that just your opinion? I'm saying maybe/hopefully and that's the best we can do at the moment.
