AMD dismisses Intel's Thunderbolt

While the world and its dog has been running stories about Chipzilla’s new Thunderbolt technology, AMD says that it is not particularly impressed.

While we would not expect AMD to unwrap the bunting for its rival’s latest efforts, it is doing its best to dismiss the Thunderbolt input/output technology as just another proprietary standard with not a lot of chances to be adopted widely.

A spokesman for AMD told Xbit that AMD could not see how Thunderbolt brings any tangible improvements.

At issue are the existing standards which seem to be better than what Chipzilla is offering. Thunderbolt can manage 10 Gb/s bandwidth if the wind is behind it and it is going downhill.

This means that it does not substantially outperform current generation I/O technologies and sometimes even offers lower bandwidth.

Existing standards allow good connectivity as a bonus and can still go faster than any of the peripherals that are available.

DisplayPort1.2 standard offers up to 17Gb/s of peak bandwidth for displays. The total bandwidth for a Thunderbolt channel is only 20 percent higher than one PCI Express 3.0 lane and about 52 percent higher than a single USB 3.0 port.

AMD said it was daft to use the mini DisplayPort connector for the technology as this reduces bandwidth available for displays connected to the mDP port.

AMD said that using Thunderbolt in the DisplayPort connectors decreases the bandwidth available for DisplayPort, reducing the bandwidth available for various multi-display configurations.

While Seagate Technologies and Western Digital do support Thunderbolt and plan to introduce HDDs featuring the interconnector later this year, only high-speed solid-state drives will be able to actually use the higher bandwidth.
