Asked if by 'too fragile' he meant there were incompatibility issues with AMD (NYSE: AMD) architecture, Dell said, "Yes, and that's vital."
Lunatic fringe?
"These are system issues that underlie the integrity of our own brand," Dell said.
AMD is preparing a response to Dell's comments.
Dell recently criticized Intel for a component shortage that cost Dell several hundred million dollars worth of lost sales in the December quarter, fueling speculation that Dell would turn to AMD as a second source of chips.
Describing some of his customers as being at the "lunatic fringe" of computer use -- those users who are happy to remove and replace peripherals such as sound or video cards -- Dell said: "We found the AMD environment to be much more fragile ... than equivalent Intel systems."
