PCI CPU expansions

[eden]

I've seen these around some shops, for Macs it seems, though I had heard they had PC editions too.
Does anybody know why they weren't popular?
An extra 400MHZ ain't bad really, especially if you put an array of them being barely any heat productive.

Been a while since I had looked at such devices, maybe a couple of years. At the time they were expensive. The cards had their own memory but not much of it. I seem to remember they cost about 50% more than a motherboard+CPU+memory (at retail prices). They didn't perform very well when any I/O needed to be done. Video would be slow having to pass data through the PCI bus and then through AGP port. Lot's of latencies. PCI bus becomes totally saturated so general performance drops considerably.
