AMD Only Producing Octa-Core Zen Summit Ridge CPUs in the Initial Wave
A new report has just surfaced on the web which suggests that AMD will only be producing octa-core Zen based processors—at least, initially.
Since AMD has just to design a single die, the strategy will help the chip maker cut costs. Not only that, but this first wave of Zen x86 CPUs, called the Summit Ridge, will be exceptionally powerful as well.
The report comes from Bits&Chips which further suggests that the method will allow AMD to commercialize 8-Core and 6-Core Zen Summit Ridge CPUs in the retail market, and that these CPUs could debut with or w/o Hyperthreading (HT) enabled.
Even if the yields are exceptionally bad, OEMs could still use 4-Core CPUs—so there will be no dual-core Zen chips.
The 8-core Summit Ridge CPU dies have already taped out in January. The CPUs are rumored to feature a 95W TDP, and will be released on the new AM4 socket. With both these features on board, the next gen desktop FX CPUs from AMD will indeed be very power efficient, and should be on par with Intel’s upcoming line of “Broadwell-E” processors.
AMD’s Zen chips are built using the new 14nm FinFET process technology. The CPUs will bring greater than 40% improvement in instructions per clock (IPC) over their current lineup – which is undoubtedly a big jump by any standard.
Last but not least, these new FX CPUs include support for a new socket with DDR4 memory and PCI Express Gen 3.0.
