New Ryzen Processors and VRay

[vlado]

So from some preliminary tests, the Ryzen 7 1800X works pretty well, it's a little more than 2x faster than my current i7-4771 workstation.

I did have to use the Ryzen Master tool to peg the CPU clock speed though, otherwise the clock speed of the cores went up and down and CPU usage hovered around 97%-99% all the time when rendering with V-Ray, even though the CPU temperature was quite low and Windows power profile was set to "High Performance". It seems to me like some kind of glitch with Ryzen's power savings/clock boost logic.

Once I fixed the clock speeds to 3700 MHz for all cores in Ryzen Master, CPU load was at 100% when rendering and it gave me 3%-5% render time reduction compared to the defaults.

I also timed other CPU benchmarks, it's interesting that the speed-up factor compared to my i7 was not consistent. For example, Cinebench was the same as V-Ray with 2.15x render time reduction, but the Corona Benchmark was only 1.97x.

Scenes that I tested for V-Ray were the two scenes from VRayBench and ArchInteriors'37, scene 6. Benchmarks ran 3 times and I took the average values.

Best regards,

Btw the Ryzen is exactly as fast as an old machine that has dual Xeons E5-2680 @2.7 GHz that cost a small fortune a few years ago

Ill be keeping a close eye on future developments as that sounds very cool considering its just as fast and less than half the price

Thanks for the results Vlado, I'm pleased to hear since I'm picking up my Ryzen 1800X system parts tomorrow, after building I plan to clock it to 4.2Ghz on water as per Scan.co.uk pre-built systems and use it as a render node. Spec includes a quick Samsung 128Gb M2 PCI SSD. Full system comes in at under ?1200 incl VAT.

hi,
when will VRayBench be available?

and thank you for the Ryzen results. Hope to have a comparison with newer CPUs like 5960, 6900, 6800, etc when VRayBench available.

[vlado]

hen will VRayBench be available?

Almost done...

Best regards,
Vlado

[mohammadreza_mohseni]

great news. thank you

[Morbid Angel]

do you guys know if you can have two ryzen in one mother board?

[benb32]

Nope, not as of all the currently released products on the market. However, there are rumours that Asus are building a motherboard that could fit two CPUs... it's not explicit whether this is going to be for the server market with the Naples 16C 32T CPUs. If you're hoping to do both CPU and GPU do look closely, multiple GPU support (more than 3) doesn't appear to be as straightforward as on intel CPU motherboards - hopefully this will clear as more people test.

There's some Rysen benchmarks at evermotion. And it's looking good, very good:

Yes, AMD is really killing it in terms of performance per dollar. Nothing that Intel can compete with at the moment in this segment. AMD did it this time and I'm happy for the breath of fresh air in the CPU market after a decade of Intel domination. However, I'm waiting to see how this pans out before shopping for AMD's excellent new processors. Even if it was a false rumor, I would have waited anyway as I want to give it some time for the BIOS'es and drivers to be ironed out of the bugs and slowdowns.

[benb32]

Plus only two memory controllers - I would guess that limits a workstation to 64GB. At least until the server parts become available in the second half of the year...

[Jiri.Matys]

Vlado, can you show us what scene will be rendered in VRaybench? Iam really looking forward

[vlado]

These are the two scenes that we have in the first version:

For the GPU CUDA benchmark:


For the CPU benchmark:


Best regards,

Vlaod, will the team release the benchmark scenes for both Max and Maya or?
