Hi there,
Being a newbie I throw myself at the mercy of the forum.
Small question - how come they didn't leverage the PCI Express and needed a new bus (excuse me, p2p interconnect) altogether?
On the protocol side, I imagine it is rather adequate.
And if pcix16 is good enough for display card, shouldn't it, or its senior brother, pcix32 be good enough, while leveraging existing h/w?
