The 18 core i9-7980XE is widely thought[1] to be a direct response to the 16 core Threadripper announcement. It was announced late, with much less info. It has a expected release date months later than the rest of the i9 lineup, and is using higher core count silicon that Intel has previously only ever used in Xeons.
Can you recommend a better article on retail availabilty of Kaby Lake Xeon?
> Intel kind of quietly slipped out the Kaby Lake Xeon E3 processors right smack in the middle of its Technology and Manufacturing Day last week, and it did not make a big deal about it.
This is relevant to customers buying Xeon E3 hardware. Over the last few weeks, OEMs quietly added Kaby Lake Xeons to some existing devices. Because the chips are compatible with existing motherboards, there were no new devices to be announced. With little coverage of this announcement, it is easy to end up buying an i7 Kaby Lake or a E3 Skylake on a device, if you did not know that E3 Kaby Lakes are now shipping.
Phoronix is, once again, wrong. Skylake does not support the SHA instructions. The only currently shipping x86 CPUs which support them are Intel Goldmont (Atom) and AMD Zen (Ryzen, Threadripper).
Mainstream support for SHA in Intel CPUs will come with Cannon Lake, or whatever the next microarchitecture revision they release ends up being.
* Yes, Cannon Lake is technically shipping as the i3-8121U, but that isn't really relevant to anyone here.
You can find the previous article at [1], which goes over the basics and the original finding on Skylake. This new article focuses on Ice Lake but probably mostly makes sense after reading the original. HN discussion of the first part is at [2].
I'm actually surprised they could narrow it down even that much. The skylake and coffeelake iGPUs always seemed basically identical to the kabylake one.
The new 18-core i9-10980XE isn't out yet, and review embargoes haven't been lifted. We know it's a slightly clock bumped version of the i9-9980XE, which was included in the AnandTech review and not the Linus review.
Linus tested the 8-core i9-9900KS, which came out a few weeks ago, and those results are also in the link which is the title to this thread.
Disappointing that those boards won't see the new more cored processors.
There's some... interesting power consumption with the latest i9 OC'ed. https://www.eteknix.com/intel-core-i9-7980xe-extreme-edition...
