Hum, I guess it's really 12cores, speedwise. Adding cores is like adding processors, but splitting a core into threads just splits that processor into halves, adding more flexability, but not more speed really.

Too bad they aren't using the 8core chips, making 16 total cores (32 threads), I know I could sell my boss on buying a few of those. :)

...should not they put Xeons 3.2 & 3.33 in Apple store offer before? I am not against new 6 core processors but why one cannot buy Mac with fastest processor possible, will it stay this way?

What 8 core processors?

The big iron ones for 4+ Socket sytem, where a single CPU costs more than a Mac Pro.
He means those :D

Not quite, HT adds 15-25% if the application multi-threads efficiently.

OH nice I didn't know that. Sounds good to me! And yes, I was talking about the 8core quad CPU technology that was just announced, hehe. It may be a while before they are affordable enough to stick into consumer computers.

Is lightwave 9.6 capped at 16cores? My pull down list stops there. (I'm sure I could find this with a search, but just wondered)

Well, basically it keeps parts of the internal CPU pipeline busy that would otherwise be idle when running one thread per core.

The same goes for the AMD 8- and 12-cores I guess.

9.6. is, I think versions following it have a higher limit.

If 9.6 sees the hyper-threading, then using the new CPUs would see a significant limitation. You'd lose 4cores or 8 threads.. buggers. That would be heart breaking!

In my eyes there is no LW other than 9.6 or prior. Maybe 9.6.1 soon. Wonder if they plan on upping core usage for that.

It doesn't make a difference to an app, HT is seen as separate cores.

The next builds that we issue of LightWave HC and LightWave v9.6.1 will have the renderer thread support increased.

Yes, but will it work on a mac? :devil:

Just checked, I have 32 in LW HC right now. :)

i've yet to install lightwave HC!...maybe i should!!!

You should, I am using it every day. :)

And if you would add CUDA/OpenCL support into that renderer, I think we all would all feel better about it.

How do you say... PLEASE?! ;-)

Too bad they aren't using the 8core chips

the 8core version is much lower-clocked than the new 6 core versions (as it's built using the older 45nm process instead of 32nm). It's not really intended to be used in workstations - more for heavily-threaded server loads. The new 5600 xeons would kick its *** for LW and AE.
