AMD today took wraps off a processor family that constitutes arguably the company's most important launch in years. Codenamed Naples, that family is now known as AMD Epyc.

Epyc represents AMD's firm intentions to return to the x86-based server market dominated by Intel after the effective demise of the Opteron chips from a heyday in 2003.

Appreciating that Intel holds a near monopoly in server-class CPUs and chipsets, AMD has much to gain and little to lose.

We'll discuss the various models, talk through the architecture underpinning Epyc, evaluate benchmarks provided by AMD on a Tech Day yesterday, and then see if Epyc, as an ecosystem, has the wherewithal to challenge the incumbent Intel Xeon chips that hold market-share hegemony.
