Intel and IBM, with other companies' support, have issued a proposal to enhance PCI Express technology to address the performance requirements of new usage models, such as visualization and extensible markup language. The proposal, codenamed "Geneseo", outlines enhancements that will enable faster connectivity between the processor - the computer's brain - and application accelerators, and improve the range of design options for hardware developers. Applications that will benefit include visualization, such as complex weather modeling; math and physics, such as data intensive financial applications; and content processing, such as the encryption and decryption of communications infrastructure data.

Geneseo is supported by key technology companies including Adaptec, AGEIA Technologies, Altera, Broadcom, Celoxica, Cisco Systems, ClearSpeed Technology, Dell, EMC, Emulex, HP, Integrated Device Technology, Lecroy, Linux Networx, LSI Logic, Mellanox Technologies, Myricom, NetEffect, Novell, NVIDIA, PLX Technology, PMC-Sierra, QLogic, Sun Microsystems, Synopsys, Tektronix, Xambala, Xilinx. and Xtreme Data.

PCI Express technology was first delivered in client and server computing platforms in 2004. Its introduction signaled the transition of computing platform I/O from the parallel bus model that had existed since the PC industry's inception to a high-speed, serial I/O standard. Since this time, millions of PCI Express-enabled platforms and devices have been delivered to customers, and PCI Express has emerged as the industry's choice for platform I/O and internal interconnect connectivity.
