R15 Render Speed

Thought I'd put up a few real world tests to show the new Embree stuff.

R14: 8:23
R15: 5:59

Excellent, thanks for these.

In some cases you get a huge speed-up using Embree up to 300%. It's the new default for the Physical Render. You can still choose between the old Physical raytracer and Embree though.

Physical (R14): 3:54
Embree (R15): 1:14

That's pretty special

Cool. Faster is GOOD. Thanks for sharing

I'm curious as to any cases in where the old physical methods would be faster than embree. I mean if there is an option what is the option there for? do the results differ notably, as they don't appear to, so are there cases where embree might strain compared to the old method, or limitations?

You have got to ask this on the intel forums

Btw. apparently this stuff is completely free, which i think is amazing . Did not expect that from a big company.

Interesting, thanks. Does this mean that it runs slower on AMD machines?

As long as the CPU supports SSE3 (which most AMD CPUs do) all is fine.

No.

Embree is faster in most situations, but under certain conditions it can be slower. That and backwards compatibility are why the old methods were kept.

Edit: It needs SSE3, but that is a prerequsite for R15 anyway.

Everything runs slower on AMD machines.
