The PCI bus can operate at the same time as the CPU, VL cannot.
Richard,

That may be true .. put the prove in on the pavement. In the reviews
that I have seen where two boards from the same mfr .. in the same
CPU computer are compared .. the PCI was either nearly identical in
performance or slightly less than PCI. PCI is a "smarter" technology
.. maybe these added smarts are comming at a cost?
>> PCI is a "smarter" technology
That's the ticket. Most of the boards today are somewhat just "ported
over" and don't really take advantage from all of PCI's features.
These features, however, are more visible in hard disk controllers
and network cards than they are in Video Display Adapters. I'm not
putting VLB down. If history serves as an indicative, the third party
folks always come with something better (Weitek, Chips & Technology,
Western Digital, etc.). Now is just a matter of playing catch up. PCI
has the same "restrictions" as the VLB bus (32 bits, 33 MHz, etc.)
It's going to be interesting to watch both "2nd generation" specs
reaching the market. Both VLB2 and PCI2 offer lots of features. Let's
see who stays and who goes.
You won't see any VLB on a PowerPC or a AXP machine, Gus. IMHO, PCI is the way
to go.
