… This MI450 chip – really a bunch of chiplets that look like a single unit, as has been the case for AMD datacenter GPUs for many generations now – has its compute streaming processors etched using 2 nanometer processes from Taiwan Semiconductor Manufacturing Co and is expected to be able to process… …
… The Maia 100 had a dozen ports running at 400 Gb/sec to deliver an aggregate of 4,800 Gb/sec 600 GB/sec into each Athena compute engine, which is two-thirds of what an NVLink port has going into a “Hopper” H100 or H200 GPU or one of the pair of “Blackwell” B200 or B300 chiplets in a Blackwell socke… …
… With HyperPorts, four 800 Gb/sec ports are lashed together to look like a single 3.2 Tb/sec port, offering 44 percent lower AI job completion time compared to doing ECMP adaptive routing over four independent 800 Gb/sec ports. …
… Instead of craving 800 Gb/sec ports, split that 51.2 Tb/sec switch ASIC so it supports 512 ports running at 100 Gb/sec. …
… Each server node has 400 GB/sec of Ethernet bandwidth eight ports at 400 Gb/sec , and the Rebel100 cards are hooked to each other and to the host CPUs with a PCI-Express 5.0 all-to-all interconnect. …
… That is 256 CPUs with a total of 22,528 cores and 512 TB of main memory and 300 TB/sec of bandwidth across that memory. Presumably this will be called a Vera CPX rack, with CPX being short for Compute Processing Rack not to be confused with the Rubin CPX processor . …
… The HPC6 instances came in two flavors: One based on a “Ice Lake” Xeon SP v3 processor from Intel and one based on the custom Milan Epyc 7R13 processor from AMD. …
… The second is the approximately $10 billion all-stock, not cash deal to acquire Inphi Corp in October 2020. Inphi was a maker of digital signal processors used in optical transceivers that also make amplifiers, laser drivers, memory buffer chips, and a bunch of other things. …
… The device has 40 network ports, twice the number as its predecessor, and support for 64 Gb/sec Fibre Channel and 100 Gb/sec Ethernet, and an internal fabric designed for 128 Gb/sec Fibre Channel and 200 Gb/sec and 400 Gb/sec Ethernet speeds. …
… The current NVSwitch 4 and 5 ASICs from Nvidia deliver 1.8 TB/sec of bandwidth per port and have 7.2 TB/sec of aggregate bandwidth. …
