Inside NVIDIA
Vera Rubin.
The complete hardware supply chain and investment map behind NVIDIA’s next AI platform—covering HBM4, wafers, packaging, optics, power, racks, CPUs and networks.

SKHY
MU
One platform.
Three kinds of exposure.
The cleanest investment mistake is to label every AI-infrastructure company a “Rubin supplier.” Some companies sell a part inside NVIDIA’s reference system. Others enable the surrounding datacenter. A third group merely competes for the same capital budget.
SK hynix should be in the primary list. It has a direct HBM4 relationship with NVIDIA, and its new Nasdaq ADR—SKHY—began trading on 10 July 2026. Its absence from an exchange-listed screen after that date is an omission, not a taxonomy choice.
Intel belongs, but only with a configuration label. DGX Rubin NVL8 uses two Intel Xeon 6776P host processors. The rack-scale Vera Rubin NVL72 instead centers NVIDIA’s own Vera CPU. Arm supplies architectural IP economics; NVIDIA designs Vera; TSMC manufactures the silicon.
Arista, Cisco and Marvell belong in the comparison, not automatically in the base bill of materials. Arista and Cisco address scale-out Ethernet and cluster operations. Marvell is strategically connected through custom silicon, optics and NVLink Fusion. NVIDIA’s reference rack still relies heavily on NVIDIA-designed NVLink, ConnectX, BlueField and Spectrum networking.
Confirmed content
A named component, manufacturing step or reference-system design win: NVIDIA, SK hynix, Micron, TSMC, Intel in NVL8, and the confirmed rack/power/optical manufacturers.
Ecosystem exposure
Products deployed around the rack or enabled through partnerships: Arista, Cisco, Marvell, Arm, server OEMs and optical vendors whose exact SKU content can vary.
Demand & alternatives
Hyperscalers and neoclouds buying accelerated infrastructure, plus AMD as a CPU/GPU comparison—not a confirmed Vera CPU supplier.
Rubin is not a GPU.
It is a system.
NVIDIA describes Rubin as a full-stack platform spanning compute, memory, scale-up fabric, scale-out networking, DPUs and rack-scale infrastructure. The economic value moves through multiple layers before the first token is generated.
The Rubin GPU performs accelerated compute and is paired with HBM4. The Vera CPU feeds and coordinates the system. NVLink 6 binds accelerators into a coherent scale-up domain. ConnectX-9 and BlueField-4 handle high-speed connectivity and infrastructure processing. Spectrum-6/Spectrum-XGS extends the fabric across racks. Power conversion, liquid cooling, copper, optics, PCBs, advanced packaging and final system integration make the architecture physically deployable.
This is why revenue attribution must be conservative. NVIDIA may name an ecosystem partner without disclosing its content per rack; an OEM may ship Rubin systems while capturing only a thin integration margin; an optical vendor may benefit from cluster scale without having a transceiver inside every reference rack.
Who builds what—
and how certain is it?
| Company / ticker | Hardware or role | Classification | Evidence boundary |
|---|---|---|---|
| NVIDIA NVDA | Rubin GPU, Vera CPU, NVLink 6, ConnectX-9, BlueField-4, Spectrum-X/Spectrum-6 | Platform owner | Direct, disclosed NVIDIA products |

| Intel INTC | 2 × Xeon 6776P host CPUs in DGX Rubin NVL8 | Direct in NVL8 | Do not generalize the socket win to Vera Rubin NVL72 |
| Arm ARM | CPU instruction-set/IP economics behind Arm-compatible Vera cores | IP exposure | NVIDIA designs Vera; Arm does not manufacture the CPU |
| Arista ANET | Scale-out AI Ethernet switching and operations | Adjacent | Not a confirmed component inside the reference rack |
| Cisco CSCO | Enterprise AI networking; Cisco OS with NVIDIA Spectrum silicon | Partner | Real NVIDIA partnership, principally cluster/enterprise layer |

The labels matter.
The sockets are different.
NVIDIA Vera CPU
NVIDIA designs the Arm-compatible Vera CPU and couples it to Rubin at rack scale. TSMC supplies manufacturing. Arm receives IP-related economics, but does not build the physical processor.
Intel Xeon 6
NVIDIA’s published NVL8 configuration names two Intel Xeon 6776P host processors. This is a direct, configuration-specific design win and the strongest reason to include INTC.
AMD EPYC
AMD is relevant to AI-server capital allocation and x86 alternatives. Without a disclosed Rubin reference-system CPU SKU, it belongs in the comparison set rather than confirmed content.
NVIDIA
NVLink, ConnectX, BlueField and Spectrum form the default networking stack.
Arista
High-performance Ethernet fabrics connecting AI clusters, with strong hyperscaler exposure.
Cisco
Networking, security and operations, including systems combining Cisco software with NVIDIA silicon.
Marvell
DSPs, optical connectivity, custom accelerators and an expanding NVLink Fusion relationship.
Double-digit growth—
forecast, not promised.
The most useful screen is the next fiscal year over the current fiscal-year estimate. Fiscal calendars differ, and the figures are non-GAAP where the data provider reports adjusted EPS. These numbers answer “who is expected to grow?”—not “who will beat?”

Fastest paired growth
Among the supplier/adjacent set, the most aggressive consensus combinations are:
Growth with direct content
The cleaner direct-exposure shortlist combines disclosed content and double-digit consensus growth:
*Intel content is specific to DGX Rubin NVL8.
Where the screen fails
IBM misses both thresholds; Cisco misses revenue; loss-making neocloud EPS growth is not economically comparable to profitable-company EPS growth.
Growth has a price.
Sometimes a very high one.
Prices are 17 July 2026 closes. Forward P/E and forward P/S are point-in-time consensus ratios checked 19 July. A low multiple can represent cyclicality or risk; a high multiple can represent quality, scarcity—or expectations with no room for error.

The buyers—and
the leveraged buyers.
Suppliers monetize the build. Hyperscalers monetize workloads running on the build. Neoclouds often monetize scarce capacity but finance a much larger proportion of the asset base. Their revenue growth can be spectacular while EPS remains negative.

*Consensus EPS transition from a loss to a small profit; percentage growth is not meaningful across zero.
Content, growth,
price, risk.
A useful Rubin thesis needs four independent answers. If one is missing, the conclusion is probably a narrative rather than analysis.
Content: Is the company’s product physically present, optionally present, or merely adjacent? Ask for the named SKU, reference design or partnership scope.
Growth: Is AI materially changing company-wide revenue and EPS, or only one segment? Small suppliers can have more percentage torque but much higher customer concentration.
Price: Does the forward multiple already assume several years of flawless execution? Compare P/E with margin structure and P/S with the gross margin required to justify it.
Risk: Memory is cyclical; optics can face inventory corrections; OEM revenue can be huge with thin margins; neocloud growth can require continuous debt and equity capital.
Allocation risk
A qualification does not guarantee volume. NVIDIA and customers can split HBM, optics and system orders among suppliers or redesign content over time.
Capex digestion
Hyperscaler spending can pause even when long-run AI demand remains intact. Suppliers experience the pause before software demand disappears.
Power constraint
Grid interconnects, substations and cooling can delay deployments after chips are ordered, shifting revenue between quarters.
Margin mix
Server OEMs can report explosive AI revenue without semiconductor-like gross margins. Revenue growth alone can overstate value capture.
Multiple compression
At 40–120× forward earnings, a company can hit estimates and still fall if the market lowers the multiple assigned to those earnings.
Estimate quality
Fresh ADRs, rapid-cycle businesses and loss-making neoclouds produce noisy consensus ratios. Treat false precision as a warning.
The corrected list
is broader—but stricter.
SK hynix is a primary Rubin supplier. Intel is a direct NVL8 CPU supplier. Arm is an IP beneficiary. Arista, Cisco and Marvell are necessary comparison names—but their exposure sits mainly at the network and custom-silicon ecosystem layer, not automatically inside the standard NVL72 rack.
The strongest “direct content plus double-digit consensus growth” cluster is NVIDIA, SK hynix, Micron, TSMC and selected power/optical suppliers. The highest projected growth often comes with cyclicality, customer concentration or rich valuation. The cheapest multiples often carry recovery risk, governance concerns or structurally lower margins.
Among networking names, Arista offers the cleanest paired revenue/EPS growth profile, Marvell offers the strongest custom-silicon and NVLink optionality, and Cisco offers broader enterprise distribution with slower top-line growth. They are not interchangeable.
Among buyers, Oracle screens with the highest paired next-year growth, while the neoclouds deliver far faster revenue growth at the cost of negative earnings and financing intensity. The winner is not simply the row with the largest percentage.
Evidence first.
Estimates dated.
Hardware classifications rely primarily on NVIDIA and supplier disclosures. Prices are 17 July 2026 closes. Consensus statistics were checked 19 July 2026 through StockAnalysis/S&P Global Market Intelligence. Fiscal periods follow each issuer; currencies remain local for TSM and SK hynix forecasts. Calculated growth equals next fiscal-year consensus divided by current fiscal-year consensus minus one.
