C-DAC Develops India’s First Indigenous Arm-Based CPUs: Flagship AUM Chip With 96 Cores, 96 GB HBM3, 320W TDP, 2024 Launch

wccftech.com:

India's Center for Development of Advanced Computing (C-DAC) recently announced that it was working on a series of ARM-based CPUs including the flagship AUM chip. Now, the company has revealed the first details of its AUM CPU which will be aimed at the HPC segment.

C-DAC said that there are working on a multiple range of options for domestic applications that will scale from chips that power smart devices, IoT, AR/VR up to HPC and data center use. Its Vega CPU series which is based on dual and quad-core designs will target entry-level clients that require low-power and low-cost chips and will cover at least 10% of India's chip requirement. The company will also prep its octa-core chips within the next three years as a follow-up to Dhruv and Dhanush Plus chips.

But that's not all, the company is also working on a power-efficient HPC chip that will be aiming the large-scale workloads as a part of the National Supercomputing Mission (NSM) program. This chip is going to be called the C-DAC AUM.

The C-DAC AUM CPU is based on the ARM Neoverse V1 core architecture codenamed Zeus. There are a total of 96 cores on the AUM chip but there are divided into two chiplets, each housing 48 V1 cores. Each chiplet has its own memory, I/O, C2C/D2D interconnect, cache, security, and MSCP sub-systems. The two A48Z-based chiplets are connected together using a D2D chiplet interconnect on the same interposer. Each chip also carries 96 MB of L2 cache and 96 MB of system cache.

For memory, the C-DAC AUM CPU uses 64 GB HBM3-5600 while also packing 96 GB HBM3 memory on-die and 8-channel DDR5-5200 memory (scalable up to 16-channels for up to 332.8 GB/s of total bandwidth).

That's a triple-memory subsystem with on-die, inter-poser, and off-chip memory
