India introduced its first AUM server processor: 96 cores and 96 GB of HBM3 memory / ServerNews

Advanced Computing Development Center (C-DAC) Department of Electronics and Information Technology, Ministry of Communications and Information Technology of India introduced the country’s first processor for servers and HPC systems. A product called AUM will enter the commercial market in the current or next year.

The solution has a chiplet layout based on two A48Z modules, each of which has 48 Zeus computing cores with Arm architecture. Thus, the total number of cores reaches 96. The clock frequency is 3.0 GHz (up to 3.5 GHz in turbo mode); the TDP indicator varies from 280 to 320 watts.

The novelty will be manufactured at TSMC using 5nm technology. The chip contains 96 MB of L2 cache and 96 MB of system cache. The product received 96 GB of HBM3 memory and an 8-channel DDR5-5200 controller; in addition, there is access to 64 GB of memory HBM3-5600. Thus, a three-level memory subsystem is involved. Up to 128 PCIe 5.0 lanes are mentioned with CXL support.

The AUM processor can be used in dual socket servers. Claimed performance exceeds 4.6 Tflops per slot. Various security features have been implemented, including Secure Boot and cryptographic algorithms.
