95% of what people say about ZFS is cargo cult behaviour.

It doesn't need ECC and it doesn't need something ridiculous like two gigs of RAM per terabyte.

I still can't get over the idea that otherwise intelligent people don't stop at the 1 gb ram per 2 tb storage (the recommended amount I've seen) and think, "Hmm, I feel like this need has more to do with the nature of my workload than the filesystem itself." :smithreddit:

Why ecc ram on a workstation?

ECC for fun and security should totally be a thing! I'm not a stakeholder in AMD or Intel, though, so I'm resigned to pointing out that a $15-20 increase (if it is indeed that low) on ecc ram may or may not do as much net good as a spontaneous bouquet of flowers for your mother or spouse, depending on whether its just a home pc for browsing or a true critical-workload workstation.

A 5-30% performance hit probably puts their IPC right back at Broadwell/Ryzen levels, doesn’t it? Zen+ might close up the gap by a lot more than expected just by virtue of getting clocks up.

If I've read benchmarks right, 5-10% pushes them back to Broadwell. 30%... is almost as far back as Sandy Bridge?

TL:DW: der8auer says that they're using real dies on TR. AMD says they're not electrically connected. der8auer delids Epyc 8c and TR 1920x showing distinct differences in components on surface. He has them X-Ray Epyc and TR by PCB analysis company. X-Ray shows that TR is electrically connected to all dies, including infinity fabrics between all dies. He speculates that AMD could be holding back on a 32c TR component.

He says that all his TR PCBs have the same 32200 code printed on them and the Epyc had 32188. Speculates it's PCB revision.

It should be out in april.

I want to see the OC benchmarks. The shrink should give it some serious OC headroom (10%-15%) compared to before. If they can hit 4.4-4.6 reliably I'll upgrade from my i7 3770k and then probably upgrade again in 2019.

2019 is also going to be a big year for AMD on the server if they deliver with zen2.

The licensing savings for SMB moving to single die, 32 core Threaddenwerffen are freaking great

x86 CPUs: The Intel/AMD Thread

It's been discussed before--and if memory serves me right--with positive responses. Nobody pulled the trigger.

If there are no serious objections, at 00:00 UTC Sunday 12 August 2018 (8 PM Saturday EST), AMD will acquire Intel (or something similarly improbable and official sounding) and I'll petition a mod to close the separate CPU threads.

Maybe we'd go through a period of PC's becoming extremely optimised for I/O etc, since that is the main area of development left as the CPU designs slow to a snail's pace.

This is already where we've gone in enterprise. Because cpus haven't been improving all that much in comparison to the conpute load humanity demands of the internet, in storage alone we are: gutting protocol overhead (SATA/SAS to NVMe), eliminating the need for storage protocols altogether (3dxpoint dimms now sold as "pmem"), and making relatively-secure storage retrieval directly from network interface to block device without even going though the cpu (RDMA). Both dx12 and vulkan are minimizing the involvement of system calls. The cpu is being eliminated as a middleman where possible.
