Description:
Blisteringly quick Ethernet speeds are being enabled by Nvidia Spectrum-X 
technology.

FULL STORY
======================================================================

Nvidia has announced details of a new networking platform designed 
specifically with generative AI workloads in mind, promising lightning-speed 
lossless networking. 

The companys new Spectrum-X technology is built using the Spectrum-4 Ethernet 
switch and BlueField-3 DPU, and promises performance and power efficiency 
increases of as much as 1.7x. 

In a press release , the company said: The delivery of end-to-end 
capabilities reduces run-times of massive transformer-based generative AI 
models, which in turn enables companies to operate and make decisions more 
quickly, unlocking cost-saving potential. Spectrum-X Ethernet 

Nvidias Networking Senior VP, Gilad Shainer, said: Spectrum-X is a new class 
of Ethernet networking that removes barriers for next-generation AI workloads 
that have the potential to transform entire industries. 

Its key component, the Spectrum-4 Ethernet switch, is capable of 51 Tb/sec 
speeds. What this means for consumers is that, in conjunction with 
BlueField-3 DPUs and Nvidia LinkX optics, a 400 Gigabit Ethernet network is 
enabled. Read more

The company looked to provide an insight into the powerful networking 
capabilities that AI supercomputers can now tap into in real-world cases: 

Nvidia Spectrum-X enables unprecedented scale of 256 200Gb/s ports connected 
by a single switch, or 16,000 ports in a two-tier leaf-spine topology to 
support the growth and expansion of AI clouds while maintaining high levels 
of performance and minimizing network latency. 

Elsewhere, Nvidia CEO Jensen Huang held up the Spectrum-4 switch chip during 
his presentation at the Computex expos opening speech, sharing more insight 
into its design. The hundred billion transistors on a 90x90 mm die draws 
around 500 watts, he said. 

Already, Nvidia is testing its Spectrum-X in its Israeli data center in the 
Israel 1, a hyperscale generative AI supercomputer running Dell PowerEdge 
XE9680 servers based on the Nvidia HGX H100 eight-GPU platform. These are the
