Sweet!

Nice but the clock is quite low. We have older two processor xeon running at 2.4 and we had to take it out of the farm as it was slowing down the whole dr so much

I think its more then just clock. But typically the cpu overclocks it self under load to 3.6 ghz, which is quite high.

About AVX 2.0.

Is there any benefit in the AVX 2.0, for Embree?
Vlado you could give us some details?

[vlado]

We are just putting together an 88-core configuration for experiments; I will let you know when we have had time to play with it.

Best regards,
Vlado

Here are the frequency bins for that CPU:
6/6/6/6/6/6/6/6/6/6/
6/6/6/6/7/8/9/10/11/12/
14/14
If the processor is being fully utilised, the maximum clock speed for the cores will be 2.8 GHz - assuming the thermal limits haven't been reached... 145 watts is a lot of heat!

I want two of those!

Dmitry, do you mean the AVX-512 extension? Remember reading something in the docs about increased calculation speed (think with the light cache..?) for certain Xeon.

[Morbid Angel]

No I mean two of the 22 core xeons I don't know what those extensions do - if they speed things up that much? any tests...

[AndresAhumada]

yes!! 512 extensions!

[AndresAhumada]

Embree flyaway!

[benb32]

knew you meant 2 of the CPUs, was referring to your question about AVX 2 with Embree. Both the core and xeon CPUS have had AVX 2.0 for a while now. From memory Embree uses special libraries to use the AVX registers/instructions to speed up the calculations performed in raytracing like algorithms, especially ones that are based on monte carlo sampling. So in a way, you can already test to see what the difference is by turning embree on and off on your current machines.

With AVX-512, as well as a few new instructions the registers have doubled from 256 bits to 512 bits with the new generation of xeon and soon to be released Phi. Intel will update their embree libraries to take advantage of this with processors that have this feature - basically you can pack more variables into the same instructions to increase your throughput and speed.

[vlado]

Yeah, I don't think it will help too much, but who knows... the Embree code is fast enough even now, it usually spends most of the time waiting for data to arrive from memory.

Vlado

I'm dreaming of a dual 2696v4 config for about 5-6k$ from parts on ebay
Just haven't got the cash just yet :-p

That's okay, just use someone else's cash I've just taken on a full-time role at my new company, and spent yesterday building my Dual 2696v3 (along with a Quadro M6000)

Be interesting to see/feel the difference between that and my own i5960x with K4200's.
