  "account": "Arm's AGI data center CPU, set to launch in late 2026, touts a two-chiplet design with 70 Neoverse V3 cores each, running at 2.80 GHz to 3.70 GHz. The processor boasts a two TB/s UCIe fabric link and a 12-channel memory controller, supporting up to 3 TB of DDR5-8800 memory (6 TB per socket). The 96 PCIe 6.0 lanes, utilizing CXL 3.0 protocol, enable memory expansion, while four PCIe 4.0 lanes, I3C, I2C, and SPI interfaces cater to other I/O needs. Arm's design choices, such as using two self-contained SoC chiplets on TSMC's N3P technology and focusing on memory locality, bandwidth, and latency, set AGI apart from AMD, Intel, and Nvidia's heterogeneous multi-chiplet designs. The CPU's sophisticated memory subsystem offers out-of-order command scheduling, bank-parallelism-optimized address mapping, programmable page policies, memory-bandwidth limiting, and monitoring for optimal performance. However, Arm has not yet published conventional benchmark results or direct socket-to-socket comparisons against current AMD EPYC or Intel Xeon processors.",
  "summary": "Arm reveals more details about its AGI processors with up to 136 cores, but fails to disclose performance.",
