Credo Technology and Astera Labs both sell connectivity semiconductors for AI and data-center systems, but their portfolios have different centers of gravity. Credo emphasizes electrical and optical interconnects, active electrical cables, signal-processing products and memory connectivity. Astera Labs presents a broader standards-based connectivity platform that spans PCIe, CXL, Ethernet, NVLink Fusion and UALink, with COSMOS software and fabric switching alongside its signal-conditioning products. They overlap, but they are not interchangeable companies or product portfolios.
At a glance: where the businesses overlap and differ
Both companies address the challenge of moving data reliably through increasingly complex AI and data-center infrastructure. Their product descriptions include signal conditioning and high-speed connectivity, and Credo’s FY2026 filing names Astera Labs in its competitor discussion. That establishes real competitive overlap, not identical product lineups.

What Credo Technology makes
Credo’s FY2026 Form 10-K describes products for high-speed electrical and optical connectivity in AI and broader data infrastructure. Its portfolio is not limited to a single link type: it includes cable-based connections, optical products, signal-processing components and memory-related solutions. The range matters because a data-center connection can involve more than one kind of component; a cable, an optical interface and a chip that conditions a signal are distinct parts of a system rather than interchangeable labels.

Cables and optical connectivity
Credo lists ZeroFlap active electrical cables (AECs) and ZeroFlap optical transceivers. An AEC is an active cable assembly: electronics in the cable help manage the signal over the connection. Optical transceivers provide an optical interface for sending and receiving data. These categories position Credo across both electrical and optical interconnects, rather than making it an optical-only or copper-only supplier.
The company presents these products as addressing needs such as power efficiency, reliability and high-speed connectivity. Those are company-stated priorities, not independently verified comparative performance results. The available disclosures do not provide a head-to-head test showing how a particular Credo cable or transceiver performs against an Astera product under the same conditions.
For a reader comparing product choices, the important first question is therefore not simply which company has an “optical” or “copper” story. It is what connection the system design calls for, which product category addresses that connection, and whether the exact part supports the relevant configuration. Company-level descriptions do not answer compatibility questions by themselves. The disclosures covered here do not include enough product-specific configuration detail to make those decisions for a particular system.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsDSPs, retimers and SerDes
Credo also lists optical and copper Ethernet and PCIe digital signal processors (DSPs), retimers, and SerDes chiplets and intellectual property (IP). These products sit in or support the signal path between system components. In broad terms, signal-processing and retiming products help preserve or manage data signals as they travel through a system; SerDes technology converts data between serial and parallel forms. The exact role depends on the product and system design, so the categories alone do not determine which component a system builder would use.
Credo’s combination of cables, DSPs, retimers and SerDes means its business covers more than a single chip category. Its FY2026 filing describes these products as part of a portfolio serving high-speed connectivity needs, but it does not establish that every product is used together or in the same customer system. Nor does naming Ethernet and PCIe DSPs establish that every product supports every generation or configuration of those standards.
Retimers are a useful point of overlap in the company descriptions: both businesses discuss signal-conditioning products, but the label alone cannot tell a buyer whether two parts have the same function, features or suitability. A meaningful technical comparison would require the product-level specifications, supported standards, system conditions and implementation requirements for the candidates under consideration. The cited company disclosures do not provide a controlled, side-by-side test.
Memory connectivity and PILOT
OmniConnect is Credo’s named memory-solutions family. The filing also describes PILOT diagnostic and analytics software associated with link monitoring and system operation. These extend the disclosed portfolio beyond cable and signal-conditioning hardware, but the available information does not provide a comparable software-feature matrix for Credo and Astera.
Rank #2
- GIGABIT ETHERNET PORTS: Features 5 x 1.0Gbps Ethernet ports for high-speed connectivity. Auto-negotiating ports detect the optimal speed for connected devices and work with existing Cat5e or Cat6 Ethernet cables.

- SILENT & ENERGY-EFFICIENT OPERATION: Fanless design ensures silent performance, while IEEE 802.3az Energy Efficient Ethernet reduces power consumption without compromising high-speed network performance.

That distinction is worth keeping clear: PILOT is described in terms of diagnostics, analytics and link monitoring, while the available Astera description positions COSMOS within an integrated connectivity platform. The difference in how the companies describe their software does not establish that one has broader features, a better user experience or greater customer adoption. The disclosures also do not quantify how much either software offering contributes to sales.
What Astera Labs makes
Astera Labs describes its Intelligent Connectivity Platform as spanning CXL, Ethernet, NVLink Fusion, PCIe and UALink, integrated with the COSMOS software suite. It says its standards-based portfolio is complemented by custom connectivity solutions. That is a platform-level framing: the company groups products, interconnect standards and software into a wider connectivity proposition rather than describing its business only through individual component families.
The list of standards helps explain the breadth of the platform story, but it should not be mistaken for a guarantee that each product addresses each standard, or that all listed technologies are at the same commercial stage. Product selection still depends on the particular part, its intended role and the system configuration. The company description alone is not a part-number compatibility guide.
Aries and Taurus signal conditioning
Astera’s Q2 FY2026 release highlights Aries products for signal conditioning. It also describes Taurus Smart Retimers and Smart Redrivers for 224G Ethernet and UALink. Retimers and redrivers both address signal conditioning, but the product names and stated standards are not enough to infer identical implementation, performance or system role. The source does not provide a controlled comparison with Credo’s products.
Astera’s mention of 224G Ethernet and UALink is a specific product-family description in the Q2 release; it should not be generalized into a claim that all Astera products target those connections. Similarly, Credo’s disclosed Ethernet and PCIe DSPs and retimers should not be assumed to match Taurus or Aries part for part. The public portfolio descriptions identify areas of activity, while a detailed design-in decision would require more granular specifications.
Scorpio fabric switching and the production ramp
Astera also highlighted its Scorpio X-Series fabric switch. In its August 4, 2026 Q2 FY2026 release, management said the 320-lane Scorpio X-Series was expected to drive a Q3 revenue inflection through its production ramp. This is a forward-looking expectation, not confirmation that the ramp occurred or that it produced a particular amount of revenue. Readers should distinguish this statement about expected future contribution from the company’s reported Q2 revenue.
The 320-lane figure is a product descriptor in the company’s announcement, not a measure of realized sales or proof of customer adoption. The release’s wording indicates that management expected the product’s production ramp to affect a later quarter. It does not establish the timing or scale of actual deliveries, the revenue ultimately recorded, or the product’s competitive position. Those outcomes would need to be assessed against later company reporting rather than inferred from the expectation.

COSMOS and the platform approach
Astera presents COSMOS as integrated with its connectivity platform. That makes software part of its stated platform narrative, alongside products associated with several interconnect standards and fabric switching. Credo, by contrast, describes PILOT as diagnostic and analytics software tied to link monitoring and system operation. These descriptions indicate different ways the companies talk about software; they do not show which offering is more capable, easier to deploy or more widely adopted.
“Platform” can describe the way a company organizes and markets a portfolio, but it is not itself a performance result. In this comparison, Astera’s phrase points to its combination of standards, products and COSMOS. Credo’s disclosures show a set of hardware families and PILOT software with stated diagnostic functions. Neither framing establishes that a customer needs every element, that the offerings are directly substitutable, or that one approach is superior in a given deployment.
How to compare their product strategies
Start with the connectivity layer
Credo’s disclosed product mix makes its emphasis on active electrical cables, optical transceivers, DSPs, retimers and memory connectivity especially visible. Astera’s platform description makes the standards and system-level connectivity scope more visible: CXL, Ethernet, NVLink Fusion, PCIe and UALink, plus signal conditioning and switching.
This is a difference in portfolio emphasis, not a clean boundary. Both companies address data movement in AI and data-center infrastructure, and their product categories overlap around high-speed connectivity and signal conditioning. Credo explicitly identifies Astera as a competitor. A buyer evaluating a specific design would still need to compare the exact product, supported standard, configuration and system requirements rather than infer a match from company-level labels.
A useful comparison starts by identifying the job a component must perform: for example, whether the design calls for an active electrical cable, an optical transceiver, a signal-conditioning component, memory connectivity or fabric switching. Next, identify the applicable standard and the exact system constraints. Only then can a product-family comparison narrow the field. The company descriptions support this disciplined approach, but do not supply all the technical details needed to select a part.

A platform that lists several standards is not automatically a substitute for every cable, DSP, retimer or memory-connectivity product in another portfolio. Conversely, a portfolio with products across electrical, optical and memory connections is not automatically a complete fabric-switching platform. The companies’ own descriptions support a comparison of scope and emphasis, not a claim that one has a direct counterpart for every product offered by the other.
Product names and roadmap language also need careful interpretation. A product highlighted in a quarterly release, a product family listed in an annual filing and a product expected to ramp are not necessarily at the same commercial stage. In particular, Astera’s Scorpio production-ramp reference was an expectation for Q3, as stated in August 2026; it should not be treated as a completed result on the strength of that release alone.

Do not infer a software winner
Astera’s COSMOS is presented as part of an integrated platform, while Credo’s PILOT is described in connection with diagnostics, analytics, link monitoring and system operation. Those statements help readers understand the companies’ positioning, but they do not form a head-to-head software comparison. The disclosures cited here do not establish feature parity, customer adoption, or operational advantages for either suite.
Keep claims and evidence in separate buckets
There are at least three different kinds of statements in a comparison like this. First are reported figures, such as revenue for a defined fiscal period. Second are descriptions of products and their intended roles, which should be attributed to the companies unless independently tested. Third are expectations, such as a planned production ramp, which describe management’s outlook rather than a completed outcome. Mixing these categories can make a portfolio sound more proven or a financial result more comparable than the disclosures justify.
The same discipline applies to growth language. A company can report a strong year-over-year change without that alone showing why it happened, how repeatable it will be, or whether it implies a future market-share lead. The figures here are useful context for the scale and recent trajectory each company reported, but they do not establish customer wins, product performance or future returns.

The latest financial figures presented here are from different reporting periods. Credo’s figure is for a complete fiscal year, while Astera’s is for a single quarter. Comparing the raw totals as if they measured the same amount of time would be misleading.
| Company and period | Reported revenue | Additional reported context |
|---|---|---|
| Credo FY2026, year ended May 2, 2026 | $1,335.116 million | FY2025 revenue was $436.775 million. FY2025 had 53 weeks; FY2026 had 52 weeks. |
| Credo Q4 FY2026 | $437.0 million | Credo reported 157.0% year-over-year revenue growth and a GAAP gross margin of 68.2%. |
| Astera Labs Q2 FY2026, quarter ended June 30, 2026 | $392.4 million | Astera reported 104% year-over-year growth and a GAAP gross margin of 73.3%. |
These are company-reported results. Credo CEO Bill Brennan said that in FY2026 revenue more than tripled to $1.3 billion and non-GAAP net income increased more than five times to $662 million. That is an executive’s summary of Credo’s year, not an independent assessment. Credo’s fiscal-year comparison also spans periods of different lengths: FY2025 had 53 weeks and FY2026 had 52, which matters when reading its year-over-year change.
The reported annual revenue figures show that Credo’s FY2026 total was substantially higher than its FY2025 total, but readers should preserve the fiscal-year labels and remember the differing week counts. A 53-week prior year compared with a 52-week current year is not a perfectly equal-duration comparison. That caveat does not erase the reported figures; it is context for interpreting the growth rate rather than treating the calendar periods as identical.

Astera CEO Jitendra Mohan described Q2 FY2026 revenue as a record $392.4 million, up 27% sequentially and 104% year over year, and attributed the result to broad-based strength across the portfolio, including record quarterly Aries revenue. Those are management’s statements about the quarter. The quarterly growth figure should not be set directly against Credo’s full-year revenue or annual growth claim.

The two gross-margin figures also should not be used as a direct company ranking. Credo’s 68.2% is for Q4 FY2026, while Astera’s 73.3% is for Q2 FY2026; both figures are identified as GAAP, but the periods differ. A fuller financial comparison would require aligned periods and additional context beyond these selected reported results. A sound comparison would also distinguish quarterly from annual results and avoid using one line item as a proxy for overall profitability or competitive strength.
In practical terms, Credo’s $1,335.116 million is a full-year measure, while Astera’s $392.4 million is a three-month-quarter measure. Dividing or annualizing either number to force a comparison would require assumptions not provided by these results and could obscure seasonal, timing or business differences. The figures are best read as separate snapshots with explicit periods, not as a head-to-head scorecard.
What this comparison can—and cannot—tell you
The available company disclosures support a useful product and business comparison: Credo has a visible emphasis on cables, optical products, signal-processing components and memory connectivity, while Astera describes a multi-standard platform that includes software and fabric switching. They also show that the companies have some competitive overlap. They do not answer which company will win more designs, gain market share, deliver future growth, or produce better shareholder returns.

Frequently Asked Questions
Are Credo Technology and Astera Labs competitors?
They have partial competitive overlap. Credo’s FY2026 filing names Astera Labs among its competitors, and both companies describe high-speed connectivity and signal-conditioning products for AI and data-center infrastructure. Their portfolios are not identical, so the label does not mean every product directly competes with a counterpart.
What does Credo Technology make?
Credo’s FY2026 portfolio description includes ZeroFlap active electrical cables and optical transceivers, OmniConnect memory solutions, retimers, optical and copper Ethernet and PCIe DSPs, and SerDes chiplets and IP. It also describes PILOT diagnostic and analytics software associated with link monitoring and system operation.
What does Astera Labs make?
Astera describes an Intelligent Connectivity Platform spanning CXL, Ethernet, NVLink Fusion, PCIe and UALink, integrated with COSMOS software. Its Q2 FY2026 release highlighted Aries signal-conditioning products, Taurus Smart Retimers and Smart Redrivers for 224G Ethernet and UALink, and the Scorpio X-Series fabric switch.
Which company had higher revenue?
The figures cited cover different periods and should not be treated as a direct ranking: Credo reported $1,335.116 million for FY2026, the fiscal year ended May 2, 2026, while Astera reported $392.4 million for Q2 FY2026, the quarter ended June 30, 2026. One is a full-year total and the other a quarterly result.

No. In its August 4, 2026 Q2 FY2026 release, Astera said the 320-lane Scorpio X-Series was expected to drive a Q3 revenue inflection through its production ramp. That was management’s forward-looking expectation, not confirmation of a completed ramp or a stated amount of Q3 revenue.
The Bottom Line
Bottom line: Credo and Astera both serve high-speed connectivity needs in AI and data-center infrastructure, but Credo’s disclosed center of gravity is cables, optical connectivity, signal processing and memory solutions, while Astera presents a multi-standard platform with signal conditioning, COSMOS and fabric switching. They compete in parts of the market, not necessarily product for product. Credo’s FY2026 revenue and Astera’s Q2 FY2026 revenue cover different time periods, and neither company’s product claims or reported growth alone establishes which business will win future designs or which stock will perform better.
