A 16x graphics card uses 16 lanes and a 4x pci uses four but
eventually you MAY? saturate your superio chip. Intel may be switching
to something more like amd or have heat issues on the superio but I
doubt that. You would saturate it quicker on an atom however but then
it supports less ports.

PCI-E is certainly not the bottleneck. I would be far more
likely to believe the want to sell intermediary chips.
