I am also bothered by "Optane support" it's the reason why I stated it supported Optane Memory while Cascade Lake supports Optane DC persistent memory.

That's what I was dreaming of getting when I first heard about Optane and where it would eventually go. Don't think I'd be able to afford that though :/ Maybe in a few more years I'll find it on ebay.

I wonder how much that optane is limited by the cpu. With ram being so much faster you wouldn't think it could be, but my cpu clocks definitely have an impact on my 900p. I just made a screenshot with cdm at 3.0 core/3.0 cache vs 4.2 core/3.9 cache. I switched the clock multiplier with XTU and that gives some multicore use each time I use it, but CrystalDiskMark runs single core for me. I listed the chronological order of the tests too in case anyone ever has theirs run in a different order. I also don't have the spectre mitigations installed, and temporarily disabled meltdown protections just to make my scores a bit higher

Edit: The 900p is on the cpu's pcie lanes too, chipset is only gen 2 with Z97.

Persistent memory would be awesome too. Pcie is holding it back. Also, it isn't that much faster over pcie than an ssd with rapid mode enabled imo, unless you do big things, in that case it never slows, never bogs, never needs optimization.
You probably already know this, I'm just bothered by "optane support" being tossed out there as a blanket statement when in the case of Kaby Lake it was Optane as a cache suport.
They have real os sized m.2 Optane sticks now too, so the cache thing is more of a footnote, kind of like hybrid hdds.

Yep! I used a Samsung 960 Evo Nvme boot drive on my Z87 devil's canyon system. You need to insert a file into your bios with a freely available tool and then reflash your board. Works great and speeds everything up quite a bit.

bigjdubb Intel's Core Architecture laurels were so large that they had no choice but to sit on them.

I never said it wasn't due to AMD's competition that allows us to see Intel flex their engineering skills. Even though they are using their UPI to link the two dies the latency between them is still quicker than Epyc/ThreadRippers infinity fabric when jumping over to the next die(Not CCX, Infinity Fabric's CCX jumps are slower than Intel's Mesh)

The Core architecture is on 9 generations and it's still able to compete with AMD's new architecture. Their next generation is out in 2021 and we'll get to see if they make another massive leap in technology just like they did with the Ring bus.

Used parts unfortunately, although the 7980XE seems like a decent bin, only spent a couple hours tweaking it and waiting on some liquid metal to come in for the direct die mount. This CPU is actually one of two that the seller had, the previous one being the 7980XE that BPS customs reviewed. Seller was actually a really nice dude.

TBH I think intel needs to start releasing big-little HEDT proc's with 4-8 5-5.5ghz cores for linear tasks and 10-20 'lite' cores 3.5-4.5ghz for big compute tasks. Though I think that's where they are headed with their chiplet designs? with memory chips onboard?

10nm was supposed to be "next year" for the past 4 years or so now. But it seems even that has slipped. So rather than being "next year", it's now "next year + 1".

By examining the data for the past 4 years, we can deduce that 10nm gets delayed at the rate of approximately 15 months per year. Extrapolating to 2021, Intel's 10nm will be on the roadmap for 2023 or 2024. When 2024 rolls around, Intel's 10nm will be slated for 2027.

The takeaway here is that 10nm is moving away faster than we can approach it. It is beyond the comoving distance of the expansion of the universe and is therefore beyond the causal event horizon. Therefore it will never arrive.
