August 23rd, 2023, could have been formally declared “Nvidia day.” If you happen to have been a expertise fanatic or investor it was not possible to keep away from the information, which was all over the place: The cloud infrastructure expertise firm’s blowout earnings and forecast for its fiscal second quarter was fueled by market-dominating chips and programs that run synthetic intelligence (AI) infrastructure, because it exceeded its income forecast by $1.4 billion.


“You are seeing the — the info facilities all over the world are taking that capital spend and focusing it on the 2 most essential traits of computing at the moment, accelerated computing and generative AI,” mentioned CEO Jensen Huang on the convention name.

The corporate raised its steerage for the 12 months, issuing an eye-popping forecast that fiscal third-quarter income will likely be about $16 billion, a mere $3.4 billion or so larger than the $12.61 billion that the analyst consensus forecast. That steerage signifies 170% progress from the year-earlier interval.

As you learn within the media at giant, the story has largely been pinned to Nvidia’s dominance in graphics processing models (GPUs), the constructing blocks of generative AI. At the moment NVIDIA enjoys a close to monopoly on high-powered chips for AI, together with its A100 and H100 chips, no less than till main competitor AMD begins delivery its extra aggressive chips later this 12 months. At the moment, Nvidia has an enormous backlog, and might’t even sustain with demand


However there’s one thing bigger occurring right here: Nvidia’s dominance throughout the AI stack — together with software program, reminiscence, storage, and networking. Nvidia executives pointedly attributed the expansion to promoting complete programs – such because the HGX – that are constructed on NVIDIA GPUs but in addition are built-in with highly effective networking and software program.

“Information heart compute income practically tripled 12 months on 12 months pushed primarily by accelerating demand for cloud from cloud service suppliers and enormous shopper web corporations for our HGX platform, the engine of generative and enormous language fashions,” mentioned Colette Kress, Government Vice President and Chief Monetary Officer of Nvidia, on the convention name.

The Full Stack Makes NVIDIA Stickier

It’s not nearly GPUs. AI programs are refined supercomputing platforms that should be networked collectively, optimized with software program, and use 1000’s of elements. To optimize an AI system, engineers should take a “full stack” method.

Nvidia has the lead not solely in chips but in addition throughout the stack, together with essential networking expertise from Mellanox, which it acquired in 2019, in addition to key software program optimization elements.

Simply to provide the sense of scale: A single HGX A100 system has 1.3 terabytes of GPU reminiscence and a pair of terabytes/second of reminiscence bandwidth. The storage handles 492 of SSDs and exterior networking capability is 400 gigabits/s.

Don’t anticipate Nvidia to cease filling extending the AI stack. It’s been steadily making key acquisitions concentrating on AI programs to construct HGX. In 2022, it acquired Excelero for block storage programs and Vivid Computing to drive excessive efficiency compute (HPC) clusters. In February, Nvidia aquired OmniML, a AI software program firm designed to allow machine-learning fashions to run on any system.

Whereas the bigger world appears to be targeted on Nvidia’s lead in GPUs, it’s actually in regards to the full stack, even coming all the way down to intensive software program libraries, which Nvidia executives identified on the convention name.

“So, this runtime referred to as NVIDIA AI Enterprise has one thing like 4,500 software program packages, software program libraries and has one thing like 10,000 dependencies amongst one another,” defined Huang on the decision. “And that runtime is — is, as I discussed, constantly up to date and optimized for — for our set up base for our stack. And that is only one instance of what it could take to get accelerated computing to work that the variety of — of code mixtures and kind of utility mixtures is admittedly fairly insane.”

Community Is the Subsequent Battle

It’s arduous to see anyone placing collectively the complete stack in a manner that Nvidia has. The networking entrance has gotten extra fascinating recently, the place essential opponents equivalent to Arista Networks have gotten an AI bump as hyperscalers improve their networking wants to attach AI servers.

Arista Networks has additionally been AI investor favourite in 2023, deriving networking progress from the AI increase. In reporting its second quarter fiscal 2023 earnings earlier this month, Arista reported 39% year-over-year progress, fueled by demand from hyperscalers equivalent to Microsoft and Meta. One in all its progress drivers is upgrades to larger bandwidth programs to drive AI workloads, mentioned Arista executives.

“The AI alternative is thrilling,” mentioned Arista CEO Jayshree Ullal. “As our largest cloud prospects evaluation their basic cloud and AI networking plans, Arista is adapting to those adjustments, thereby doubling down on our investments in AI.”

Probably feeling somewhat neglected, Cisco Techniques performed up AI wares on its earnings convention name every week in the past. Cisco is releasing upgraded Ethernet switches with a brand new line of Cisco Silicon One ASICs designed to compete with AI networking programs based mostly on NVIDIA’s InfiniBand. Cisco, with rival Arista, is a part of the Extremely Ethernet Consortium.

However to date, Cisco hasn’t been seen as huge an AI play by traders. For instance, Cisco’s year-to-date acquire is 17%, whereas NVIDIA is up 225% and Arista is up 51%. And neither Arista nor Cisco have GPUs and full-stack integrations.

When Will NVIDIA Dominance Be Challenged?

The underside line is Nvidia has constructed an AI system enterprise within the quickest rising market in cloud. Generative AI corporations that wish to construct processing services don’t have a lot selection at this level – they will both lease house within the public clouds, which have constructed their very own infrastructure and in some circumstances their very own AI chips, or they will purchase Nvidia programs and processors. Nvidia has been forward of this pattern however now all people is chasing it.

With Arista and Cisco coming after Nvidia in AI networking, it’s clear Nvidia goes to be challenged on numerous fronts. However for now, the Nvidia frenzy you see is prone to stay for no less than the remainder of the 12 months. AMD’s new AI chip, the MI300X, gained’t be out for no less than one other quarter, so Nvidia will proceed to money in. The opposite closest opponents are the cloud corporations themselves – Amazon and Google – which have designed their very own chips for AI, having accurately foreseen the attainable chip scarcity. The networking opponents have items of the puzzle — however they don’t have the complete system with software program optimization.

What could also be underestimated is the deep strategic thought and planning that Nvidia has put into its complete programs, from the networking interconnects to the software program elements. Rivals have quite a lot of work to do in the event that they wish to knock Nvidia off the highest of the AI infrastructure hill.
