Leaked 256-core Zen 6c EPYC CPU destroys Zen 5 in early single-threaded benchmarks hints at 24% IPC gain

Unconfirmed test results for an alleged 256-core Zen 6c EPYC server processor suggest significant single-threaded performance advantages over previous-generation Zen 5 hardware. Independent frequency-normalised assessments point towards potential instructions-per-cycle gains of roughly 24 per cent alongside increased clock speeds. If verified, the architecture could mark a substantial leap forward for AMD's enterprise data-centre silicon portfolio.
