AMD Ryzen 7 series and Corona?

[cecofuli]

No, we haven't any news about dual AMD CPU system.

[Ondra]

that makes me wondering.. what makes them not doing prevention for non-intel cpu to use embree while the embree it self is developed by intel?

I would say part not being total dicks, part possible negative response from anti-monopoly regulators and general public ;)

Finally AMD Ryzen is released.
-Ryzen 7 1800X, 8core/16thread, 3.6Ghz-4Ghz turbo, 95W, 499USD , cinebench:1617
-Ryzen 7 1700X, 8Core/16Tthread, 3.4GHz-3.8 GHz turbo, 95W, 399USD ,cinebench: 1532
-Ryzen 7 1700, 8Core/16Thread, 3.0 GHz- 3.7GHz turbo, 65W, 329USD ,cinebench: 1403

the cinebench score is crazy. they hit the 1600 score with 500USD cpu.
cant wait for how coronabench score it.... :D
their server series Naples seems doesn't come in this pre-release.

I think we can think about something around the 2minute mark for the 1800x :) Judging how it is faster than 6900k I think that would be a relatively safe assumption.

Man I can't wait to see how Ryzen performs once the reviews get published. At this moment, even if the supposed price cuts you posted are true, Ryzen is still insanely valuable. I mean 6900k which is supposedly slower is still like 400$ more expensive than Ryzen.

Yeah, it has 40 PCI-E lanes but so far the gains of 4 GPUs on x4 APPEAR (not tested by myself) to faaaaar outweigh 2 GPUs on x8. I mean it isn't even a competition by any means.

I can see the appeal if you are really future-proofing yourself and plan on having 3+ PCI-E drives and 4 GPUs but other than that... It just seems like a hefty premium you pay. In that case I would even advocate a Xeon / Naples build with 80 lanes.

Granted though, currently the market for 4 PCI-E gpu motherboards on Ryzen is non-existent. I doubt however that that will be the case in the coming months though.

If you are CPU rendering and thinking about an i7 type of CPU... I really don't see much option but going the Ryzen way... If the published numbers are true that is. Great to see the CPU market be vibrant again!

It will function fine with corona in my opinion.

[hybaj]

It's here and it's amazing (for the price)

at 9:51 Corona render times!!!

I7-6900K - 128 seconds
Ryzen 1800X - 138 seconds

Looks Ryzen is great in Corona :)

[cecofuli]

It's great to see how a 65W AMD CPU have only a 500.000 Rays/s less than 145 Watt! It's simple amazing!
Also, with a 1/3 of the price.
I think that I will wait for the new AMD 32 CPU core for our next renderfarm upgrade. Bye bye Xeon!

[Sintel]

I see Ryzen 7 better in many test. Seems there is something about optimization with RAM bus

[Christa Noel]

based on this https://forum.corona-renderer.com/index.php/topic,5624.msg95727.html#msg95727

When first implemented, embree made waaay bigger difference in Corona than 30% - it is líke some crazy unicorn pony magic!
I also tested embree on an AMD rig, and it was not significantly slower. I suspect Corona is slower there because I only develop and optimize on Intel. Maybe sometimes in the future I will try to optimize also on AMD.

With Ryzen at the door a lot of people will switch to AMD, maybe it is time to consider fine tuning Corona to be AMD friendlier.

that is the plan!

hi Ondra, I'm very interesting about "your optimization plan" you said before. I have few questions :)
when will you start to do it? :)
does it able to disturb most of corona features & bugfix development schedule? :/
and, approximately, how far will corona codes optimization increase the AMD Ryzen performance with corona? :D :D
thanx for polishing every potential side of technologies

[Fritzlachatte]

These days, there might be a lot of people, thinking of swithing to the great Ryzen CPUs. It sounds like real candy, if there would be some optimization potentials. But I think there is enough preasure on you guys to fulfill the deadline for 1.6 ;-) But mayyybeee .....?!

Have the AMD server CPUs in past been much more expensive, I always asked myself (and google) of buying the ryzen now or waiting for dual cpu naples systems, but not for >1000€ per CPU.

we will get the chips, profile the performance, and see if there is some quick win we could do. But I cannot promise you anything. It is already performing well, so it is unlikely we would be able to get say another 20% boost.
