Chip biz AMD today, after months of teasing, debuted the second generation of its Epyc server processor family in San Francisco, promising performance, efficiency, throughput, and security improvements.

At a keynote presentation on Wednesday afternoon, Lisa Su, president and CEO of AMD, claimed the second generation Epyc, code-named Rome, is "the highest performance x86 processor in the world." Pointing to Intel's Cascade Lake line as a baseline, Su said, "We are almost double their performance." That translates to somewhere between 40 per cent and 50 per cent lower operating expenses, according to Su.
