Instead of providing power numbers based on the generally used "thermal design power" (TDP) rating, the company provides power consumption performance specifications for Barcelona based on ACP (Average CPU Power), a rating that AMD also introduced today. Rather than specifying the worst case scenario, the company told us that it is trying to provide a real world indication, how much power these CPUs will consume. While the HE versions of Barcelona have a TDP of 65W, AMD says that these processors will not consume more than 55W (ACP); the standard versions carry a TDP of 95W, but should not use more than 75W in real-world applications, AMD says.
