My fantasy build for dedicated Boinc

Just missed it

[Alez]

Unfortunately I need new race chassis etc. for next year

On most projects the 2990WX does about 1.5X my dual Xeons E5 V4s. However I ran some SRBase this week and the Intels blow the doors off the 2990WX. AMD did a crappy job of AVX implementation.

Next summer the TR3 will come out (rumor 96-128 threads) and AMD is saying they are going to fix AVX and also double the FP processing speed. If that is true it will be an absolute monster!

[davidbam]

which e5 v4 though? Even one Xeon 2696 / 2699 is more expensive than the 2990WX - and that one at auction went for close to 40% off of the usual price

[Bryan]

I have dual 2695 V4 ES (72t) and dual 2683 V4 production (64t).

The point was that the shortcomings of the TR2 will be rectified with next summer's release. I'm happy with my 2 2990WX however I won't build a 3rd one ... I'm waiting for the next generation.

[davidbam]

Yes - I do appreciate what you are saying. I'll be hoping for price on the 2990WX to drop sharply when next gen comes out & will look at the bang-for-buck, and bang-for-watt figures then

[davidbam]

Do you think, if I asked nicely, they'd join TSBT and crunch for us overnight?

I thought exactly the same. If this happened I would suspect it could exhaust all projects within hours.

[scole of TSBT]

Well based on Intel's latest leaked info, my build would have a W-3175X CPU (28c/56t, 3.1 ghz/3.7 all/guess, 6 channel DDR4 and plenty PCIe lanes for 2 Titan Vs and a couple M.2 drives)

[Dirk Broer]

Based upon AMD's last leaked info, my dream build would have a Ryzen Threadripper from the 3000 'Castlepeak' series, rumoured to have 64 cores for the top model.
Rumour also have it that this generation will allow dual socket mobo's for them Threadrippers, which would mean a possible 128 real cores/256 threads on one mobo.
It could turn out to be however that the 64 cores come from the dual mobo and that the platform will -for the time being- max out at 128 threads.
I hope that there will be 64GB ECC UDIMMs at decent speed and price too at the launch date...and dito 128Gb ECC UDIMMS when the 64-core CPU becomes reality

What will be the next step? Four threads per core, eight perhaps?
Still more cores seems to create serious heat problems -those 64-core Threadrippers 3990WX Black Editions are rumoured to require a 360mm AIO cooler, and the most expensive option comes with a bundled 480mm AIO cooler, and a NZXT case.

I hope they finally fix the AVX capability. The 2990WX flat sucks in comparison to Intel Xeons on SRBase or PG. On projects that aren't AVX intensive the 2990WX kick butt.

Threadripper, Threadripper 2 and Threadripper 3 might benefit from optimized AMD applications, preferably built on a non-Intel compiler. And from libraries that do not have lines in them as

If vendor_string equals Intel then ...
else goto ...

[Bryan]

They would also benefit if the AVX registers could do both multiplication and division like the Intel architecture. AMD has said they will fix it in TR3 because they have a piss poor implementation that hobbles their CPUs versus the Intel's. They also said they wouldn't support AVX 512 yet. They said they will double FP processing speed. The TR3 is going to be a monster!
