Coverage of LPDDR5x in the Nexus archive.
- A deep dive into Nvidia's Vera CPU and the Olympus cores that power it
Nvidia's Vera CPU, featuring 88 custom Armv9.2 cores and a monolithic compute die, challenges Intel and AMD by targeting AI workloads and cloud providers like Alibaba and Meta. The chip supports standalone operation, 1.5 TB of LPDDR5X memory, and dual-socket configurations via NVLink-C2C with 1.8 TB/s bandwidth.
- Intel's mysterious new datacenter GPU is what Nvidia's Rubin CPX nearly was
Intel's Crescent Island datacenter GPU uses LPDDR5x memory with up to 480 GB, contrasting with industry-standard HBM/GDDR. It aims to address AI workloads similar to Nvidia's shelved Rubin CPX, which prioritized cost-effective prefill acceleration. The shift to disaggregated compute architectures separates prefill and decode phases, reducing reliance on high-bandwidth memory.
