Pretty sure it is under water. His other screenshots show it idling at 18c...I'm pretty sure LN2 does not do that.

18c idle probably means an ambient temp of 10-12c. So this is probably as good as it gets, except for those seasoned pros who go out of their way to crank windows open in the winter, or even running lines to rads filled with antifreeze and placed outside.

Yeah...the room is definitely cool. I keep my thermostat ~70f and I'll idle will flash between 19c-22c.
 
Don't bite my head off, but I really believe that Skylake X should have its own thread.

Let's face it, Skylake-X has nothing to do with Skylake, Kabylake and Coffeelake. Ok it shares similar micro architecture, but an LGA 2066 product does not belong on a LGA 1151 thread.

Why do we all Coffeelake fans should have to skim through pages and pages of LGA 2066 info is beyond me.

We decided to try and have a 14nm thread (this one) and a 10nm (for another thread). It is long. You can make a Coffee Lake thread if you want and see what sticks.

Even on i7-7820X? Doesn't it only have half-throughput AVX-512? 😱
Click to expand...

I am getting 611 Gflops on a 7820X on AVX-512 LinX (using Intel latest compiled code) only running at 3.6Ghz. That number tells me that the 7820X is utilizing full AVX-512 bandwidth.

Edit: Double precision tests

If memory serves the 7900x can do the fused 256x256 as well as having a dedicated 512bit port.

Unless the 7900X is pushing over 1.2 Tflops in AVX-512 code (which I doubt), I believe all Skylake-X skus have the dedicated port activated. I hope someone can post LinX numbers on their 9700X for comparison.

I guess I don't completely understand. Is the 7800x and 7820x AVX512 performance actually gimped compared to the 7900x? The throughput benchmarks in that post I linked seem to show the same throughput per core between the 7800x and 7900x.

Not gimped. Review sites appeared to be incorrect.

This appears to be accurate. Which is strange because Intel is selling SP Xeons that don't have the additional unit enabled (eg: Gold 5xxx and lower)

All the new Xeon-W's have both AVX units enabled as well. (Same socket as Skylake-X). Xeon-SP seems to be the only ones without both units enabled. And for the prices they are asking for them, seems odd to me.

I could stick it back in with my beyond CFL thread, but it depends on what the majority wants.

Cool, so that is Intel confirmed? Not just the random marketing team things that have popped up..
May have to go the other route if so.

They more or less confirmed that in their known video.

Back to topic, there is another i7-8700k listing from an EU based shop.

i7-8700k 365.00 € https://www.bm.lv/en/intel-core-i7-8700k-hexa-core-370ghz-12mb-lga1151-14nm-box-bx80684i78700k
i7-7700k 354.00 € https://www.bm.lv/en/intel-core-i7-...z-8mb-lga1151-14nm-95w-vga-box-bx80677i77700k


Price is very close to i7-7700k. And that's an early shop listing, Intels official price listing might be identical to Kabylake therefore.
