"The multi-chip processor uses 7nm process technology for the "Zen 2" CPU cores that benefit from the advanced process technology, while leveraging a mature 14nm process technology for the input/output portion of the chip". Nearly certainly, the Ryzen 3 family will make use of the 7nm Zen 2 architecture, which could see AMD push ahead of Intel in the raw performance and clock speed stakes, as Intel is still on the 14nm process node given it has kept pushing back the debut of 10nm-based CPUs due to problems with manufacturing them at scale. Let's take a closer look. But rather, they have unveiled their next generation EPYC CPU dubbed "Rome".
AMD today claims to own the world's first 7nm data center CPU.
The chipsets contain no memory controller or PCIe, but are instead tied to a central IO chip built on 14nm. The CPU chips which are called chiplets by AMD are connected to the I/O die through an "enhanced version" of the company's Infinity Fabric interconnect link.More news: Brad Pitt ‘concerned’ about his upcoming custody trial
The chiplet isn't the only new feature.
One of AMD's mainstay features is socket compatibility for those that have already adopted previous generation processors. We can expect Zen 2 to come to consumer parts as well, after the EPYC processors, so some of the information shared here may still be relevant. AMD showed a pre-production, air-cooled, non-overclocked Rome outperforming a dual-socket Skylake SP with 56 cores and 112 threads in the floating-point intensive C-ray benchmark. What exactly gets ported over to Ryzen, however, isn't known. At a minimum, we'd expect the same 8-core chiplets to be scaled down for desktop use. A Zen 4 processor is also in the works, although no timeline was given for its debut. The next jump with Zen 2 is much larger at 7nm. Futhermore, this has also waylaid Intel's plans for significant performance improvements.
The roadmap for Zen started with the first design in 2012. If the claims hold up, the second-generation processor has a shot at being the highest performing datacenter CPU in 2019.More news: Rihanna Tells Donald Trump to Stop Playing Her Music at Rallies
Rome is now sampling with customers and is expected to ship sometime in 2019, at which point we'll find out about all the product specs: SKUs, clock frequencies, cache sizes, pricing, and so on. We know Lisa Su is scheduled to deliver a keynote at CES in January.
"The availability of multiple AMD EPYC processor-powered instances on Amazon EC2 instances marks a significant milestone in the growing adoption of our high-performance CPUs with cloud service providers", said Forrest Norrod, senior vice president and general manager, Datacenter and Embedded Solutions Business Group, AMD.More news: South Korean minister: United States says N.
