I thought that was part of the issue, removing the PCI bus from the CPU/GPU connection. Of course, the APU has a lower memory bandwidth than the pure GPU, but in theory now the PCI bottleneck is gone. > * Power (CPUs in servers today max out around 120W with GPUs at >250W) I see this as more of a smearing out of the GPU (SIMD unit). Instead of one big GPU sitting on the PCI bus shared by 2-4 sockets, now each socket has it's own GPU on the same memory bus. Unless, I'm not following the APU design correctly. > > Either way we're in for an interesting future (as usual) :-) Indeed. > > /Peter > _______________________________________________ > Beowulf mailing list, [email protected] sponsored by Penguin Computing > To change your subscription (digest mode or unsubscribe) visit > http://www.beowulf.org/mailman/listinfo/beowulf > -- Doug -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. _______________________________________________ Beowulf mailing list, [email protected] sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
