US researcher tracks system bus statistics

A new analyst report has claimed PCI Express (PCIe) has reached a state of ubiquity in the PC market.

According to statistics from US-based research outfit, In-Stat, the PC system bus created by Intel in 2004 will be inside 440.2 million devices by 2010. It further claimed that it was built into 17 million communications boards last year, growing to 37.2 million boards in 2010.

Plus Corporation managing director, Nigel Fernandes, said PCIe had been steadily taking over for the past 12 months.

"It's become the standard these days - especially for graphics cards," he said. "Over the past year it's been replacing AGP-based graphics cards which could only operate at 8x speed. PCIe can operate at 16x speed."

Gamers were particularly appreciative of PCIe as it enables them to run two cards simultaneously in Scalable Link Interface (SLI) mode, Fernandes said. Almost all high-end graphics cards from the ATI and Nvidia stables now use PCIe.

While there are rival architectures being developed, including HyperTransport, InfiniBand and StarFabric, Fernandes said PCIe was well-entrenched and likely to be the industry's default standard for some years to come.
