Real or hoax? Threadripper 3990wx
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Don't know about that - but if you get two of these on one motherboard , you are looking at 240,000,000 nps (SF) at a minimum.

Re: Real or hoax? Threadripper 3990wx
I think that number is high.
I guess it would be 30% more due to instruction efficiency than two AMD 7601 32 core CPUs, which get 127,342,246 NPS, which is: 165,544,920 NPS
And then the loss for CPU speed of 2.7 GHz moving down to to 2.0 GHz gives 122,625,867 NPS
Pretty nice score, but I would be very surprised at 240,000,000 NPS. Now, with 2 of the 7742 chips, 241,185,105 was obtained.
https://openbenchmarking.org/result/190 ... XEPYC77437
I am considering the 7702p, but I am waiting to see the cost and performance of the threadripper first.
If it is only 32 cores, then I will be disappointed. That is why I was excited about the original link. 64 cores is listed as max core count.

7702 with 64 cores https://browser.geekbench.com/v4/cpu/14490973
7742 with 128 cores https://browser.geekbench.com/v4/cpu/14486381
the most highly correlated benchmark for Stockfish nps is the Integer Score ( although may not be as correlated for Intel vs AMD, but for the same processor brand, it is very correlated when the processors are very similar as they are here)
7742 Multi-Core Performance with 128 cores
Code: Select all
Multi-Core Score 191125
Crypto Score 64768
Integer Score 282056
Floating Point Score 197032
Memory Score 9261
Code: Select all
Multi-Core Score 134681
Crypto Score 62208
Integer Score 198539
Floating Point Score 136764
Memory Score 5992
We'll find out soon enough.

The 7742 is run in pairs for the 240M NPS bench.
Extremely doubtful that one 7702p can approach that.

However, the processors that end with a P designation cannot be run in pairs.
They require a single socket motherboard

Re: Real or hoax? Threadripper 3990wx
I knew they had single and dual socket configuration - I assumed that the "P" flavors would be run in pairs, my bad, you are correct.Dann Corbit wrote: ↑Thu Sep 12, 2019 12:24 amI see.MikeB wrote: ↑Wed Sep 11, 2019 11:50 pmAgree 100% ,and I was not suggesting that in my original post.Dann Corbit wrote: ↑Wed Sep 11, 2019 12:02 pm The 7742 is run in pairs for the 240M NPS bench.

Re: Real or hoax? Threadripper 3990wx
The pricing premium for the non p version over the p version is ~ 40% , factor of in the additional cost for the dual socket motherboard and you are looking at quite bit more than 2x premium to go from 64 to 128 cores. Currently pricing a 7702p configuration with a custom builder today. Would anyone like to guess the price - Ubunta OS , 1 TB SSD drive , assume a $750 video card and 64 GB ram. Guess the final price without delivery charges and as well the price you would be willing to pay if you had the financial resources to buy one without any undue hardship. I haven’t committed yet - still waiting for the quote. My best guess is that it will do the SF bench at 120M nps. Has anyone seen a bench from the 7702P yet?MikeB wrote: ↑Thu Sep 12, 2019 12:47 amI knew they had single and dual socket configuration - I assumed that the "P" flavors would be run in pairs, my bad, you are correct.Dann Corbit wrote: ↑Thu Sep 12, 2019 12:24 amI see.MikeB wrote: ↑Wed Sep 11, 2019 11:50 pmAgree 100% ,and I was not suggesting that in my original post.Dann Corbit wrote: ↑Wed Sep 11, 2019 12:02 pm The 7742 is run in pairs for the 240M NPS bench.
