AMD Takes Aim at Performance Leadership with Next-Generation EPYC Processor

AMD Takes Aim at Performance Leadership with Next-Generation EPYC Processor

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. With PCIe 4.0 capability it is capable of a 64 GB/s bidirectional connection to the CPU and with Infinity Fabric Links it has 100 GB/s per-link bandwidth between GPUs.

"By using the Zen 2 architecture and 7nm, on desktops", said analyst Pat Moorhead of Moor Insights.

California-based chip giant AMD has unveiled the 7nm Zen 2 microarchitecture for its future family of processors. "The result is much higher performance-more CPU cores at the same power, and more cost-effective manufacture than traditional monolithic chip designs", AMD says. 'Combining world-class performance and a flexible architecture with a robust software platform and the industry's leading-edge ROCm open software ecosystem, the new AMD Radeon Instinct accelerators provide the critical components needed to solve the most hard cloud computing challenges today and into the future. Thanks to the doubling of the core count and floating point width, AMD is claiming Rome will deliver four times the flops per socket as its first-generation EPYC offering.

Revealing the new chip tech at an AMD press and analyst event in San Francisco on Tuesday, the company said that Zen 2 represents the second and perhaps the most significant step in the architecture's timeline.

According to AMD, the dedicated I/O die offers improved latency and power consumption for the new Epyc Rome processors. "I am expecting improved raw core performance with frequency and IPC improvements positively impacting lower threaded workloads".

What is New with 7nm Zen Processors?

The roadmap for Zen began with the first design in 2016.

Why this matters: Ryzen marked AMD's comeback in consumer CPUs, so expectations are high for the second generation.

With AMD's rival Nvidia having largely cornered the high-end gaming GPU market, but with AMD promising to fight back, there were rumblings that AMD's press event late last night could bring with it the news of a new high-performance GPU - and it did, in a way: The company has announced the Radeon Instinct MI50 and MI60 accelerator boards, its first products to feature a graphics processor built on a 7nm process node, designed for accelerating machine intelligence and deep learning applications in the data centre.
