OPTPiX Image During Hot Chips 2023, a conference where the latest high-performance processor technologies are announced, reports have emerged that Intel is designing an 8-core processor with 66 threads per core. Intel held a session (The First Direct Mesh-to-Mesh Photonic Fabric) during the event and mentioned HIVE (Hierarchical Identify Verify & Exploit), a joint research program jointly conducted by DARPA and private companies. . HIVE, announced in 2017, is a project to improve processors for big data processing, which are essential for machine learning or AI technology, and aims to develop processors that exceed existing hardware by 1,000 times in performance per watt. Intel, which developed HIVE, analyzed the workload that DARPA was investigating and found that massive parallel processing was required for processing, and the cache utilization rate was lowered in the existing design. So Intel designed a new processor called an 8-core processor with 66 threads per core. By having 528 threads in one processor, massive tasks can be processed in parallel. Cache memory per core is 192KB and scratchpad memory is 4MB. The architecture is RISC, not x86, and the silicon die network uses silicon photonics, which integrates elements such as optical waveguides, optical switches, optical modulators, and light receivers on a silicon substrate. An optical network using silicon photonics is also adopted for communication between off-die sockets. The die area manufactured on the TSMC 7nm manufacturing process is 316mm2 and the area per core is 9.2mm2. The number of transistors per core is 1.2 billion, 27.6 billion in the entire die, 3,275 socket pins, and the package substrate is a BGA package. This 8-core processor thermal design power is 75W, of which 59% is used for silicon photonics. Related information can be found here.
