#PEX8112

@NanoRaptor well, "#shitpost" aside there are #CardBus cards that do #PCI and PCI -> PCIe - chips like the #PEX8112 are common so it should be possible to just go CardBus -> #ExpressCard -> #PCIe.

So the only absurd thing is the pictured miniaturization, which will likely take 10-25 years to reach that small spacial & thermal envelope.

@wyatt Espechally when PCIe->PCI is easy to convert vs. PCI->ISA because PCIe at the software layer is so transparenty "PCI but faster" that it's trivial to adapt PCIe cards to PCI with chips like the #PEX8112 that have been used by many cards like a ATi Radeon HD5450 for #PCI slot versions of said card.

@3rz @Gammitin @rasteri The problem may be that there are no PCI-X / 64bit #PCI->#PCIe chips available (at a reasonable price) to warrant such cards.

I had an #ATi #HD3450 from Sapphire with that bridge-chip that I got for a low-end system back in 2009.

  • Unlike #ISA there isn't much of a hard dependency that kept 64bit PCI / PCI-X around for long and PCIe is certainly the superior interface and 1:1 software compatible and transparent to the underlying OS.
