The problem is that there are not many alternatives. AMD claims their current CPUs are not affected, but they still have the PSP, AMD's equivalent to Intel's ME. I suppose it has not been probed as thoroughly as ME because of Intel's bigger market share. ARM CPUs are - according to Intel - also vulnerable, which disqualifies almost all other competitors. I had hoped that the Longsoon chips would amount to something; I vaguely remember Richard Stallman used a notebook with Longsoon processor, but none of the vendors I checked at the time had even heard of it. And if you are paranoid enough, a Longsoon-based system might just replace the NSA with their chinese equivalent. The only viable alternative from a technology point of view that I am aware of is the Talos Raptor workstation. Unfortunately, it is rather expensive. Okay, for a high-end workstation, the price is not unusual. But compared to the price of a regular office PC, it is very expensive.
