A key benefit here is that by using the AMD EPYC 7002 series, Supermicro can fit up to 512 cores and 1024 threads in a 2U chassis. Using high-end 28 cores, Intel Xeon 8276L CPUs at $16.6K each, we were able to only fit 224 cores and 448 threads into the Xeon based Supermicro BigTwin SYS-2029BZ-HNR we reviewed.

EPYC's 7742 competitor from intel is actually [email protected] $17K with 4.5TB mem support vs 4TB on EPYC!,so AMD is actually were very conservative to compare their pricing vs 8280M @ $13K with only 2TB mem support

That just makes Intel even more overpriced.

It's nice to see AMD go ham, even though I just finished an expensive HEDT system last year on Intel. Would be tempted to swap over to AMD but as was said, I can only wonder if Intel is in panic mode. Oh well, AMD's gain for at least a few years.

"When comparing the unmitigated performance for these server processors, AMD still led by 20% over Intel. Need we remind you that the 20% performance advantage is also while the EPYC 7742 cost much less than the Xeon Platinum 8820"

Hopefully now that these launched we will get Threadripper 3 soon. I really want a 16 core CPU with 64+ PCIE lanes.

You'll be getting one with 60 PCI-e lanes and a SB that expands into a few more. It's being nitpicky, but the distinction is there, and 12 of those 60 lanes will likely be NVMe-specific as well. It is literally 3x the expandability of X370/470/570.

Agreed though, I would like to replace my 1950X with whatever the TR3 16-core is. I hope the rumors of a early Q4 launch are true, but I feel the late-2020Q1 time frame is more realistic.

I don't know why they can't use AVX-512 with the 4k x265 tests. Afraid that Intel may spank them in that area?

Well, last I checked Intel would by default, since AMD chips don't have the AVX-512 extensions. So, yes.

AVX-512 is the only reason I am even considering an Intel CPU for my next system, since I run some code which is capable of taking advantage of it. If not for the announced price drops on the Cascade Lake X chips, I wouldn't, but 18 cores for under $1000 is actually quite tempting if I can use AVX-512 over AVX2.

But I'm still drawn to a Threadripper 3 system, simply because AMDs TDP and power draw numbers do tend to actually be realistic, rather than Intel with a (non OC'd) 9900K which can suck down double what they advertise.

I don't even have AMD in consideration for the workload I do, because it's GREATLY accelerated with AVX-512. AMD may actually be faster for my 1080p workloads, because I turn off AVX-512 for those (x265 devs say it's useless there), but I'd be losing out on my 4k workloads, which is where I enable it. Guess I'll be stuck with this 2140B for many years, if not forever, since Intel felt like locking W Xeons into "workstation" boards and to not be allowed on "server" boards. Even thought server Xeons can run on "workstation" boards...
