Does anybody have any information regarding -AMD 64bit CPUs {and dedicated motherboards(Asus maybe)} compatibility with CW cards, Thx

you can safely ignore that subject for the next couple of years, unless you're about to start something like a 'google-competition-project'.

The most interesting fact I read about 64 bit was to remove the FPU unit completely from the processor, to avoid the overhead of saving registers on task switching between CPU and FPU.

I guess M$ was the driving force behind this, as it sends almost all the power of high clocked CPUs down the drain when 128 registers have to be moved to slow main memory and later retrieved back.

In that context 64 bit makes sense, but it might also go along with a decrease in precision of certain claculations - unless someone comes up with a real smart math pack.

The performance benefits of 'workstation-like' 64 bit machines like the Apple G5 are due to an improved internal architecture and optimized IO systems and by no way related to the increased number of bits.

In fact current applications are severly slowed down by a massive overhead of adressing and calculation 'fills' - those with a little sarcasm say that the biggest improvement of 64 bit is a half-sized cache

1) Nuendo, Cubase, and Gigastudio perform superb whith the Opteron according to Steinberg and Tascam. They all demonstrated their products whith this processor.

2) For future upgrade processors you need one of those.... A64, FX51, FX53, Opteron (if you're planing to stick whith AMD)

3) Float is stronger than ever. But the rumor exsists that float will be removed from Windows XP-64. But this will hopefully only remain a rumor. However in W2003 64-bit beta version it's still available

4) Motherboard whith K8T800 chipsets and AMD8000 are superb in regards to latency. According to Steinberg they almost managed to set things to 1,5 ms for a whole project !

5) But one question still remains....how do Creamware cards perform in regards to the MV test and the achivable number of tracks (e.g.in Cubase)?

Hi Bernard, thx for the info.
I think these AMD's are quite attractive considering price/performance, and the fact that some of them run on slower clock rates and produce much less heat then 32bit "Hi- clocks", but perform on the same level or better.
Is there anyone who has a chance of testing CW cards against these machines. Eventually people will upgrade and it would be very useful to know if this is a good option.
Thanks and best regards!

Well, some good news here....

"FLOAT" is still supported !
