AMD Announces EPYC Processors Now Available on Amazon Web Services

AMD's Next Horizon event this week detailed elements of its 7nm production schedule for both graphics cards and CPUs.

AMD wasn't explicit about the clock speeds Zen 2 could facilitate but it looks likely Ryzen 3 chips will have more gigahertz to play with than their predecessors, as well as other enhancements to boost their appeal over Intel's Core processor series.

California-based chip giant AMD has unveiled the 7nm Zen 2 microarchitecture for its future family of processors. When it comes to floating point per socket performance, it's a very big 4x leap over the previous generation EPYC processor.

While Rome's 64-core/128-thread count is double that of EPYC's first-generation, Naples, CEO Lisa Su promised that users can also expect double the performance thanks to the switch to TSMC's 7nm manufacturing process. Papermaster summed it up thusly: "We're in the business of high performance". AMD boasts that a single Rome EPYC chip can outperform Intel's last-gen Xeon Scalable 8180M in dual-socket configuration when running the ray-tracing C-Ray benchmark, however this has yet to be confirmed via independent testing.

According to AMD, the dedicated I/O die offers improved latency and power consumption for the new Epyc Rome processors. But because of continued delays in Intel's 10nm effort, AMD lucked out; it will be shipping some of the fastest and most power-efficient silicon in the datacenter next year. There is a single 14nm I/O die, with eight memory controllers, with Infinity Fabric ports and PCIexpress lanes, and then 7nm chipset which handle the CPU tasks themselves.

In the slide revealing this design, we also see that while the chiplets will be made on a 7 nm process, the I/O die will actually be on a 14 nm process. For example, the I/O and Infinity Fabric chiplets in Rome are implemented on a 14nm process, since unlike the execution units, they don't need the same level of transistor density.

While Rome is sampling with customers now, AMD has not yet proffered a timescale for consumer-centric Zen 2 implementations. Since Zen 4 microarchitecture is still in design phase, chances are that processors on its base will be made using a more advanced node, so think 5 nm, but keep in mind that any guesses today are speculations at best.

The 7nm manufacturing process and indeed the Zen timeline doesn't stop with the highly-anticipated Zen 2.
