Read MoreHide Full Article
Key Takeaways
ALAB posted Q2 2025 revenues of $191.9M, up 20% sequentially and 150% year over year.
AVGO's AI semiconductor revenue hit $5.2B in Q3, rising 63% year over year with 10 quarters of growth.
Both stocks are overvalued, but ALAB shows stronger earnings surprises and higher growth potential.
Astera Lab (ALAB - Free Report) and Broadcom (AVGO - Free Report) are major players in the semiconductor connectivity landscape, particularly in PCIe/CXL retimers and AI infrastructure. While Astera Labs focuses on PCIe 6, CXL, and Ethernet products, Broadcom has established itself as a long-standing leader in PCIe switches and infrastructure software.
Per the Mordor Intelligence report, the AI infrastructure market was worth $87.6 billion in 2025 and is expected to grow to $197.64 billion by 2030, registering a 17.71% CAGR during this period. Both ALAB and AVGO are expected to benefit from the rapid growth pace.
So, ALAB or AVGO — Which of these AI-Connectivity stocks has the greater upside potential? Let’s find out.
The Case for ALAB
ALAB is benefiting from the strong momentum across its three key product families, Aries, Taurus, and Leo, which is driving its top-line growth. In the second quarter of 2025, the company achieved revenues of $191.9 million, representing a 20% sequential increase and a 150% year-over-year increase.
ALAB’s increasing demand for AI platforms, particularly those leveraging high-performance GPUs and AI accelerators, drove strong design wins and sales for products like Aries Retimers, Taurus Smart Cable Modules, and Scorpio Fabric Switches.
Expanding portfolio has been noteworthy. In May 2025, Astera Labs announced that its PCIe 6 connectivity portfolio is ramping production to fast-track the deployment of modern AI platforms at scale. The offerings include new Aries 6 PCIe Smart Gearbox, Scorpio P-Series Smart Fabric Switches, Aries 6 PCIe/CXL Smart DSP Retimers, Aries 6 PCIe/CXL Smart Cable Modules (Aries 6 SCMs), and PCIe 6 over Optics Technology.
The Case for AVGO
Broadcom is making strong efforts in the connectivity space through its strong efforts in the PCIe retimers market. The company’s launch of PCIe Gen 6 portfolio, featuring high-port switches and retimers tested for interoperability with partners like Micron and Teledyne LeCroy, is a noteworthy development.
AVGO also expanded its portfolio of optical interconnect solutions to enable AI infrastructure. The expansion includes advancements in co-packaged optics, 200G/lane DSP and SerDes, 400G optics and PCIe Gen6 over optics.
The company is experiencing strong momentum fueled by growth in AI semiconductors and continued success with its VMware integration. In the third quarter of fiscal 2025, AI semiconductor revenues reached $5.2 billion, up 63% year over year, marking 10 consecutive quarters of robust growth.
Price Performance and Valuation of ALAB and AVGO
In the year-to-date period, ALAB and AVGO’s shares have gained 61.5% and 49.6%, respectively. The outperformance in ALAB stock can be attributed to its robust and diversified portfolio.
