It’s laborious to overstate Nvidia’s AI dominance. Based in 1993,
Nvidia first made its mark within the then-new area of graphics processing models (GPUs) for private computer systems. But it surely’s the corporate’s AI chips, not PC graphics {hardware}, that vaulted Nvidia into the ranks of the world’s most precious firms. It seems that Nvidia’s GPUs are additionally wonderful for AI. Because of this, its inventory is greater than 15 occasions as helpful because it was at first of 2020; revenues have ballooned from roughly US $12 billion in its 2019 fiscal 12 months to $60 billion in 2024; and the AI powerhouse’s modern chips are as scarce, and desired, as water in a desert.
Entry to
GPUs “has turn into a lot of a fear for AI researchers, that the researchers take into consideration this on a day-to-day foundation. As a result of in any other case they will’t have enjoyable, even when they’ve the perfect mannequin,” says Jennifer Prendki, head of AI knowledge at Google DeepMind. Prendki is much less reliant on Nvidia than most, as Google has its own homespun AI infrastructure. However different tech giants, like Microsoft and Amazon, are amongst Nvidia’s greatest prospects, and proceed to purchase its GPUs as shortly as they’re produced. Precisely who will get them and why is the topic of an antitrust investigation by the U.S. Division of Justice, in keeping with press reports.
Nvidia’s AI dominance, just like the explosion of machine learning itself, is a latest flip of occasions. But it surely’s rooted within the firm’s decades-long effort to determine GPUs as common computing {hardware} that’s helpful for a lot of duties in addition to rendering graphics. That effort spans not solely the corporate’s GPU structure, which advanced to incorporate “tensor cores” adept at accelerating AI workloads, but in addition, critically, its software program platform, referred to as
Cuda, to assist builders make the most of the {hardware}.
“They made positive each computer-science main popping out of college is educated up and is aware of methods to
program CUDA,” says Matt Kimball, principal data-center analyst at Moor Insights & Technique. “They supply the tooling and the coaching, and so they spend some huge cash on analysis.”
Launched in 2006, CUDA helps builders use an Nvidia GPU’s many cores. That’s proved important for accelerating extremely parallelized compute duties, together with fashionable generative AI. Nvidia’s success in constructing the CUDA ecosystem makes its {hardware} the trail of least resistance for AI improvement. Nvidia chips could be briefly provide, however the one factor tougher to search out than AI {hardware} is skilled AI builders—and plenty of are aware of CUDA.
That provides Nvidia a deep, broad moat with which to defend its enterprise, however that doesn’t imply it lacks rivals able to storm the fortress, and their techniques fluctuate broadly. Whereas decades-old firms like
Advanced Micro Devices (AMD) and Intel need to use their very own GPUs to rival Nvidia, upstarts like Cerebras and SambaNova have developed radical chip architectures that drastically enhance the effectivity of generative AI coaching and inference. These are the rivals probably to problem Nvidia.
AMD: The opposite GPU maker
Professional: AMD GPUs are convincing Nvidia options
Con: Software program ecosystem can’t rival Nvidia’s CUDA
AMD has battled Nvidia within the graphics-chip area for almost twenty years. It’s been, at occasions, a lopsided battle. In relation to graphics, AMD’s GPUs have not often overwhelmed Nvidia’s in gross sales or mindshare. Nonetheless, AMD’s {hardware} has its strengths. The corporate’s broad GPU portfolio extends from built-in graphics for laptops to AI-focused data-center GPUs with over 150 billion transistors. The corporate was additionally an early supporter and adopter of high-bandwidth memory (HBM), a type of reminiscence that’s now important to the world’s most superior GPUs.
“For those who take a look at the {hardware}…it stacks up favorably” to Nvidia, says Kimball, referring to AMD’s Intuition MI325X, a competitor of Nvidia’s H100. “AMD did a incredible job laying that chip out.”
The MI325X, slated to launch by the tip of the 12 months, has over 150 billion transistors and 288 gigabytes of high-bandwidth reminiscence, although real-world outcomes stay to be seen. The MI325X’s predecessor, the MI300X, earned reward from Microsoft, which deploys AMD {hardware}, together with the MI300X, to deal with some ChatGPT 3.5 and 4 companies. Meta and Dell have additionally deployed the MI300X, and Meta used the chips in elements of the event of its newest giant language mannequin, Llama 3.1.
There’s nonetheless a hurdle for AMD to leap: software program. AMD provides an open-source platform, ROCm, to assist builders program its GPUs, however it’s much less in style than CUDA. AMD is conscious of this weak spot, and in July 2024, it agreed to buy Europe’s largest private AI lab, Silo AI, which has expertise doing large-scale AI coaching utilizing ROCm and AMD {hardware}. AMD has also plans to purchase ZT Systems, an organization with experience in data-center infrastructure, to assist the corporate serve prospects seeking to deploy its {hardware} at scale. Constructing a rival to CUDA isn’t any small feat, however AMD is actually making an attempt.
Intel: Software program success
Professional:Gaudi 3 AI accelerator reveals sturdy efficiency
Con: Subsequent large AI chip doesn’t arrive till late 2025
Intel’s problem is the other of AMD’s.
Whereas Intel lacks a precise match for Nvidia’s CUDA and AMD’s ROCm, it launched an open-source unified programming platform, OneAPI, in 2018. Not like CUDA and ROCm, OneAPI spans a number of classes of {hardware}, together with CPUs, GPUs, and FPGAs. So it could assist builders speed up AI duties (and plenty of others) on any Intel {hardware}. “Intel’s received a heck of a software program ecosystem it could activate fairly simply,” says Kimball.
{Hardware}, however, is a weak spot, a minimum of when in comparison with Nvidia and AMD. Intel’s Gaudi AI accelerators, the fruit of Intel’s 2019 acquisition of AI hardware startup Habana Labs, have made headway, and the newest, Gaudi 3, provides efficiency that’s aggressive with Nvidia’s H100.
Nevertheless, it’s unclear exactly what Intel’s subsequent {hardware} launch will seem like, which has prompted some concern. “Gaudi 3 could be very succesful,” says Patrick Moorhead, founding father of Moor Insights & Technique. However as of July 2024 “there isn’t a Gaudi 4,” he says.
Intel as an alternative plans to pivot to an bold chip, code-named Falcon Shores, with a tile-based modular structure that mixes Intel x86 CPU cores and Xe GPU cores; the latter are a part of Intel’s latest push into graphics {hardware}. Intel has but to disclose particulars about Falcon Shores’ structure and efficiency, although, and it’s not slated for launch till late 2025.
Cerebras: Greater is healthier
Professional: Wafer-scale chips provide sturdy efficiency and reminiscence per chip
Con: Purposes are area of interest on account of measurement and value
Make no mistake: AMD and Intel are by far probably the most credible challengers to Nvidia. They share a historical past of designing profitable chips and constructing programming platforms to go alongside them. However among the many smaller, much less confirmed gamers, one stands out: Cerebras.
The corporate, which focuses on AI for supercomputers, made waves in 2019 with the Wafer Scale Engine, a big, wafer-size piece of silicon full of 1.2 trillion transistors. The newest iteration, Wafer Scale Engine 3, ups the ante to 4 trillion transistors. For comparability, Nvidia’s largest and latest GPU, the B200, has “simply” 208 billion transistors. The pc constructed round this wafer-scale monster, Cerebras’s CS-3, is on the coronary heart of the Condor Galaxy 3, which might be an 8-exaflop AI supercomputer made up of 64 CS-3s. G42, an Abu Dhabi–primarily based conglomerate that hopes to coach tomorrow’s modern large language models, will personal the system.
“It’s slightly extra area of interest, not as common objective,” says Stacy Rasgon, senior analyst at Bernstein Analysis. “Not everybody goes to purchase [these computers]. However they’ve received prospects, just like the [United States] Division of Protection, and [the Condor Galaxy 3] supercomputer.”
Cerebras’s WSC-3 isn’t going to problem Nvidia, AMD, or Intel {hardware} in most conditions; it’s too giant, too expensive, and too specialised. But it surely may give Cerebras a novel edge in supercomputers, as a result of no different firm designs chips on the size of the WSE.
SambaNova: A transformer for transformers
Professional: Configurable structure helps builders squeeze effectivity from AI modelsCon: {Hardware} nonetheless has to show relevance to mass market
SambaNova, based in 2017, is one other chip-design firm tackling AI coaching with an unconventional chip structure. Its flagship, the SN40L, has what the corporate calls a “reconfigurable dataflow structure” composed of tiles of reminiscence and compute sources. The hyperlinks between these tiles may be altered on the fly to facilitate the fast motion of information for big neural networks.
Prendki believes such customizable silicon may show helpful for coaching giant language fashions, as a result of AI builders can optimize the {hardware} for various fashions. No different firm provides that functionality, she says.
SambaNova can be scoring wins with SambaFlow, the software program stack used alongside the SN40L. “On the infrastructure stage, SambaNova is doing a great job with the platform,” says Moorhead. SambaFlow can analyze machine studying fashions and assist builders reconfigure the SN40L to speed up the mannequin’s efficiency. SambaNova nonetheless has rather a lot to show, however its prospects embrace SoftBank and Analog Devices.
Groq: Kind for perform
Professional: Glorious AI inference efficiency
Con: Software at the moment restricted to inference
One more firm with a novel spin on AI {hardware} is Groq. Groq’s method is concentrated on tightly pairing reminiscence and compute sources to speed up the pace with which a big language mannequin can reply to prompts.
“Their structure could be very reminiscence primarily based. The reminiscence is tightly coupled to the processor. You want extra nodes, however the worth per token and the efficiency is nuts,” says Moorhead. The “token” is the essential unit of information a mannequin processes; in an LLM, it’s sometimes a phrase or portion of a phrase. Groq’s efficiency is much more spectacular, he says, provided that its chip, referred to as the Language Processing Unit Inference Engine, is made utilizing GlobalFoundries’ 14-nanometer know-how, a number of generations behind the TSMC know-how that makes the Nvidia H100.
In July, Groq posted an illustration of its chip’s inference pace, which may exceed 1,250 tokens per second working Meta’s Llama 3 8-billion parameter LLM. That beats even SambaNova’s demo, which may exceed 1,000 tokens per second.
Qualcomm: Energy is every little thing
Professional: Broad vary of chips with AI capabilities
Con: Lacks giant, modern chips for AI coaching
Qualcomm, well-known for the Snapdragon system-on-a-chip that powers in style Android telephones just like the Samsung Galaxy S24 Extremely and OnePlus 12, is a huge that may stand toe-to-toe with AMD, Intel, and Nvidia.
However not like these friends, the corporate is focusing its AI technique extra on AI inference and vitality effectivity for particular duties. Anton Lokhmotov, a founding member of the AI benchmarking group MLCommons and CEO of Krai, an organization that focuses on AI optimization, says Qualcomm has considerably improved the inference of the Qualcomm Cloud AI 100 servers in an vital benchmark take a look at. The servers’ efficiency elevated from 180 to 240 samples-per-watt in ResNet-50, an image-classification benchmark, utilizing “primarily the identical server {hardware},” Lokhmotov notes.
Environment friendly AI inference can be a boon on gadgets that must deal with AI duties regionally with out reaching out to the cloud, says Lokhmotov. Living proof: Microsoft’s Copilot Plus PCs. Microsoft and Qualcomm partnered with laptop computer makers, together with Dell, HP, and Lenovo, and the primary Copilot Plus laptops with Qualcomm chips hit retailer cabinets in July. Qualcomm additionally has a powerful presence in smartphones and tablets, the place its Snapdragon chips energy gadgets from Samsung, OnePlus, and Motorola, amongst others.
Qualcomm is a crucial participant in AI for driver help and self-driving platforms, too. In early 2024, Hyundai’s Mobius division introduced a partnership to make use of the Snapdragon Ride platform, a rival to Nvidia’s Drive platform, for superior driver-assist techniques.
The Hyperscalers: Customized brains for brawn
Execs: Vertical integration focuses design
Cons: Hyperscalers could prioritize their very own wants and makes use of first
Hyperscalers—cloud-computing giants that deploy {hardware} at huge scales—are synonymous with Massive Tech. Amazon, Apple, Google, Meta, and Microsoft all need to deploy AI {hardware} as shortly as doable, each for their very own use and for his or her cloud-computing prospects. To speed up that, they’re all designing chips in-house.
Google started investing in AI processors a lot sooner than its rivals: The search big’s Tensor Processing Models, first introduced in 2015, now energy most of its AI infrastructure. The sixth technology of TPUs, Trillium, was introduced in Might and is a part of Google’s AI Hypercomputer, a cloud-based service for firms seeking to deal with AI duties.
Prendki says Google’s TPUs give the corporate a bonus in pursuing AI alternatives. “I’m fortunate that I don’t should assume too laborious about the place I get my chips,” she says. Entry to TPUs doesn’t completely get rid of the availability crunch, although, as completely different Google divisions nonetheless must share sources.
And Google is not alone. Amazon has two in-house chips, Trainium and Inferentia, for coaching and inference, respectively. Microsoft has Maia, Meta has MTIA, and Apple is supposedly developing silicon to deal with AI duties in its cloud infrastructure.
None of those compete instantly with Nvidia, as hyperscalers don’t promote {hardware} to prospects. However they do promote entry to their {hardware} by way of cloud companies, like Google’s AI Hypercomputer, Amazon’s AWS, and Microsoft’s Azure. In lots of circumstances, hyperscalers provide companies working on their very own in-house {hardware} as an possibility proper alongside companies working on {hardware} from Nvidia, AMD, and Intel; Microsoft is considered Nvidia’s largest buyer.

Chinese language chips: An opaque future
One other class of competitor is born not of technical wants however of geopolitical realities. The United States has imposed restrictions on the export of AI hardware that forestalls chipmakers from promoting their newest, most-capable chips to Chinese language firms. In response, Chinese language firms are designing homegrown AI chips.
Huawei is a pacesetter. The corporate’s Ascend 910B AI accelerator, designed as a substitute for Nvidia’s H100, is in manufacturing at Semiconductor Manufacturing Worldwide Corp., a Shanghai-based foundry partially owned by the Chinese language authorities. Nevertheless, yield points at SMIC have reportedly constrained provide. Huawei is also selling an “AI-in-a-box” solution, meant for Chinese language firms seeking to construct their very own AI infrastructure on-premises.
To get across the U.S. export management guidelines, Chinese language business may flip to various applied sciences. For instance, Chinese language researchers have made headway in photonic chips that use mild, as an alternative of electrical cost, to carry out calculations. “The benefit of a beam of sunshine is you may cross one [beam with] one other,” says Prendki. “So it reduces constraints you’d usually have on a silicon chip, the place you may’t cross paths. You can also make the circuits extra advanced, for much less cash.” It’s nonetheless very early days for photonic chips, however Chinese language funding within the space may speed up its improvement.
Room for extra
It’s clear that Nvidia has no scarcity of rivals. It’s equally clear that none of them will problem—by no means thoughts defeat—Nvidia within the subsequent few years. Everybody interviewed for this text agreed that Nvidia’s dominance is at the moment unparalleled, however that doesn’t imply it should crowd out rivals without end.
“Hear, the market desires alternative,” says Moorhead. “I can’t think about AMD not having 10 or 20 p.c market share, Intel the identical, if we go to 2026. Sometimes, the market likes three, and there we have now three affordable rivals.” Kimball says the hyperscalers, in the meantime, may problem Nvidia as they transition extra AI companies to in-house {hardware}.
After which there’s the wild playing cards. Cerebras, SambaNova, and Groq are the leaders in a really lengthy record of startups seeking to nibble away at Nvidia with novel options. They’re joined by dozens of others, together with
d-Matrix, Untether, Tenstorrent, and Etched, all pinning their hopes on new chip architectures optimized for generative AI. It’s doubtless many of those startups will falter, however maybe the subsequent Nvidia will emerge from the survivors.
