AMD Dismisses Intel's Thunderbolt

Paul Lilly

Intel's hoping Thunderbolt, the spec formerly known as Light Peak, will change the world. So is Apple, which introduced Thunderbolt with its recently retooled MacBook Pro computers. That's fine and dandy, but AMD doesn't get what all the hoopla is about. After all, what's the point of Thunderbolt if we can get this whole USB 3.0 thing rolling? That's basically how AMD put it, CrunchGear reports .

"Existing standards offer remarkable connectivity and together far exceed the 10Gb/s peak bandwidth of Thunderbolt. These solutions meet and exceed the bandwidth utilization of many peripherals," an AMD spokesperson said.

According to AMD, if given a choice, consumers would rather ride it out with USB rather than futz around with daisy chaining devices to their monitors. On top of that, aren't mini DisplayPorts fast enough already?

"The DisplayPort 1.2 standard offers up to 17Gb/s of peak bandwidth for displays...Many AMD based platforms support USB 3.0 which offers 4.8Gb/s of peak bandwidth, AMD natively supports SATA 6Gb/s with our 8-series chipsets. The total bandwidth stated 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's talking head added.

Interesting choice of words, because 52 percent sounds pretty significant to us, though AMD's other points are well taken.
