PDAs, Cellphones, Wireless PCI Express 4.0 is being designed with tablets in mind, according to standards-setting organization PCI Special Interest Group. The PCI-Express 4.0 bus will also go into PCs, servers and embedded devices. PCIe 4.0, will transfer data at up to 16 gigatransfers per second over copper wire. That is twice the speed of PCIe 3.0, which was finalized in late 2010 and is just reaching products.

PCI-E 4.0 has *nothing* to do with tablets.
Neither one will ever come close to pushing sufficient packets and/or pixels to saturate a PCI-E 2.0 4x link (~4GBps FD), let alone a theoretical PCI-E 4.0 16x link (~64GBps FD).

Heck, even a high-end Xeon EX (w/ ~100GBps memory bandwidth) will have a hard time saturating multiple PCI-E 4.0 8x and 16x link.

PCI-E 4.0 is designed to tackle 100Gbps networks and high-end GPGPU setups.
