1.3Gig Dual PPC A1XE

[ksk]

I'm almost certain that the 1.3Ghz card will be a single CPU card without L3 cache.

But it is almost as sure that it does not become available during this year... we can hope but the economies are against it.

In the end, time (&Alan R.) will tell.  


Also a dual  750FX @ 1Ghz would be a very interesting (fanless?) product...

Right, current PPC's does not gain (any) extra speed by using DDR RAM.

It seems that also as L3 cache DDR does not perform much/any better than SDR L3 cache on PPCs.

Only in some ultimately heavy duty use the DDR system RAM has any signifficant effect on PPC systems (simutaneous high PCI&AGP&CPU&HDD&Firewire etc. traffic).

The "killer feature" of DDR for G4/G3 machines could at some point be the lower price of the memory.

PPC970 CPU will be able to fully utilize the DDR memory, but I think it takes a year or two before PPC970 exists inside Amigas.

It seems that the L3 cache does not give any huge speed improvement on 800Mhz A1G4XE machines. But for 1.3Ghz system (using 133MHz FSB) it should give big boost (~20%), same (or even more so) in high Mhz dual CPU configuration.
