So let me see you put a PCI board in a PCI Express slot.
I believed I mentioned that there is a physical incompatibilty on a
slot-by-slot basis.
It is not transparent to a person trying to stick a board in the machine.
Indeed.
So how do I put a PCI board in a PCI Express slot?
You don't, you put in the PCI slot provided by the motherboard manufacturer.
And we need more than this why?
Nobody said we needed more than that NOW, but by introducing a new
physical layer we overcome other issues.
And we need this why?
Latency.
Does it need to?
Not now, no, but one day it will.
Will it be possible to push PCI Express to a trillion exaHz? You're
claiming that compatibility should be sacrifices to gain a small increment
of performance for which there is no demonstrable need.
One day there will be a requirement, You've been around long enough to
know that buses need updating before devices come out that go beyond the
limits.
Bandwidth isn't the only advantage of PCI Express over PCI or PCI-X.
PCI Express lowers latency and provides for isochronous transfers.
Ask somebody who does real sound production of the requirements for
that, I'm sure they'll have much to say about the limitations of
existing sound cards on a PCI bus.
I'm sorry, but changing the socket just to get NO gain in performance in the
real world smacks of marketing and not engineering.
Lower latency is not engineering?
There are real requirements for this technology. If you don't need it,
don't buy it.
