After years of promises from AMD with precious little to show for the company’s CPU efforts (unless you count the collapse of its core business as a victory), enthusiasts are understandably skeptical about what Carrizo will offer. The good news on this front is that AVFS isn’t just an idea AMD pulled out of its hat. It’s an understood tradeoff that adds design complexity on the chip, but can help compensate for foundry variation, and is generally believed to improve power consumption by at least the 20% figure that AMD is claiming. Some publications claim benefits up to 45% depending on workload (bear in mind that these are very different chips and target markets).
