Let’s find out.The Case for AMD StockAMD is benefiting from its strong presence in the data center market, driven by the widespread adoption of its EPYC processors. In the first quarter of 2025, data center revenues surged 57.2% year over year to $3.674 billion, accounting for 49.4% of total revenues. The company’s strong adoption of fifth-gen EPYC Turin processors and expanding Instinct AI accelerator deployments across hyperscalers and enterprises have also been major growth drivers for its success.AMD’s expanding EPYC portfolio has been a key catalyst.  In the first quarter of 2025, leading hyperscalers such as Oracle Cloud Infrastructure and Google Cloud expanded their use of AMD EPYC CPUs. OCI Compute E6 shapes offered cost-to-performance gains, while Google Cloud launched C4D and H4D virtual machines for enhanced performance, scalability, and efficiency in general-purpose and HPC workloads.In May 2025, AMD announced the launch of the AMD EPYC 4005 Series processors, delivering enterprise-class performance and efficiency tailored for small and medium businesses and hosted IT service providers.The Case for SMTC StockSemtech is benefiting from robust performance in the datacenter market. Data center revenues hit a record $51.6 million in the first quarter of fiscal 2026, up 3% sequentially and 143% year over year. Growth can be attributed to the strong demand for CopperEdge and FiberEdge products. In the first quarter of fiscal 2026, the CopperEdge solution was a major driver, offering more than 90% power savings and longer reach than traditional cables. Building on this momentum in April 2025, Semtech launched its CopperEdge portfolio of active copper cable and on-board equalization solutions, including the GN8214, GN8224, and GN8234. These low-power, high-performance linear equalizer integrated circuits enable 800G and 1.6T connectivity for AI/ML data centers, offering longer reach and reduced power consumption compared to traditional Active Electrical Cables.The company has also strengthened its technical collaborations with leading cloud service providers and cable manufacturers, ensuring it remains a key player in next-generation data center infrastructure. With hyperscalers like Meta adopting the Catalina platform, powered by Semtech’s CopperEdge-enabled ACCs, the company is well-positioned to capture market share as AI workloads expand.Price Performance and Valuation of AMD and SMTCYear to date, shares of AMD and SMTC have lost 2.8% and 38.5%, respectively.
