May 21 saw the annual PCI Special Interest Group’s developer’s conference in San Jose , California . It seems that the move to PCI-E 2.0 is going to happen very soon with a lot of major players showing off PCI-E 2.0 technology at the conference . For the uninitiated PCI-E 2.0 has been in development for some time now and aims to double the interconnect bit rate from 2.5 GT/s to 5 GT/s . It effectively increases the aggregate bandwidth of the 16-lane link to approximately 16 GB/s.
Intel who promised to launch a PCI-E 2.0 motherboard before 2008 rolls in demonstrated unreleased AMD and NVidia graphics chips on its Stoakley chip set for workstations which offers two PCI-E 2.0 ports supporting 16 parallel lanes each. Majors like ARM, LSI, NEC and Synopsys also showed off their PCI-E 2.0 technology at the conference .
Intel is expected to release its first chipsets supporting PCIe 2.0 in the second quarter of 2007 with its ‘Bearlake’ family. AMD will start supporting PCIe 2.0 with its RD700 chipset series and NVIDIA with their MCP72 chipset .The PCI SIG is already working to define a version 3.0 for Express that could appear in products in late 2009. it will probably target 8 or 10 G transfers/second.

So come 2008, get ready to embrace express 2.0 as the new standard , also gear up for faster , high performance graphics cards which eat will eat up 300W of power on the Express 2.0 specification . How fast will the transition happen ? , looking at the merciless move from PCI to AGP and then to PCI express , I would say soon … very soon 🙂
