AMD EPYC

[Ian]

Anandtech have some information on the new lineup of AMD CPUs, aimed at the Dual-CPU (i.e. datacentre) market. For recent years, this market has been entirely dominated by Intel. Are things about to change?

On the package are four silicon dies, each one containing the same 8-core silicon we saw in the AMD Ryzen processors. Each silicon die has two core complexes, each of four cores, and supports two memory channels, giving a total maximum of 32 cores and 8 memory channels on an EPYC processor. The dies are connected by AMD’s newest interconnect, the Infinity Fabric, which plays a key role not only in die-to-die communication but also processor-to-processor communication and within AMD’s new Vega graphics. AMD designed the Infinity Fabric to be modular and scalable in order to support large GPUs and CPUs in the roadmap going forward, and states that within a single package the fabric is overprovisioned to minimize any issues with non-NUMA aware software (more on this later).
