vray and amd EPYC

[MarceloViana]

just wondering, since the new amd arch found on their new chips has more latency between CCX, does Vray and Phoenix has any code update to take advantage of this new arch from amd? like each bucket don't talk to more than 4 cores/8 threads to stay in the same CCX, avoiding latency and render faster.
I mean, how good will chaos group software run on a dual socket 128 threads EPYC server?
also, vray has any limit of the number of buckets it can render, like 128 threads will run 128 buckets right?

I don't know the answers to these questions yet. I guess we'll know more if we get to acrually test this.

Currently V-Ray has a limitation of 256 threads, although it's not difficult to expand it if needed.

thank you Vlado, i'll look forward to see what you guys bring. the best softwares(vray and phoenix) must run very well on the best server.

Someone apparently published results from the V-Ray Benchmark with AMD EPYC:

im not sure if thats an impressive score or not? i guess it is, dual processor vs quad.. 128 cores vs 144... but i dunno, i was expecting more.. the clockspeed is higher .. no?

I don't know either, it's still too early for specific conclusions.

Well, since a faster solution 8x 1080ti can render at 00:16.333, i think the actually 00:20.517 isn't that bad at all.
this is 2 epyc each one at 180W TDP, on the other side you have, two xeons and 8 gpus around 250W each
On the price Epyc win again because beyond the 2 sockets server you also have to buy the gpus.
Now even knowing that the gpu is the future of render, with cpu you have unlimited(well almost) memory pool, and also all the features that is not yet available on RT.
Is a worth think wont you say guys?
