AMD (Advanced Micro Devices) is a US semiconductor group founded in 1969 and headquartered in Santa Clara, California. AMD develops and markets central processing units (CPUs), graphics processing units (GPUs), FPGAs and system-on-chip components for PCs, gaming, data centers and embedded systems. The chief executive is Lisa Su.
Four segments
AMD reports in the Data Center, Client, Gaming and Embedded segments. For full-year 2025, AMD reported record revenue of US$34.6 billion (up 34% from US$25.8 billion in 2024) and net income of US$4.3 billion (up 164%). The Data Center business grew 32% to US$16.6 billion, driven by EPYC processors and Instinct accelerators; Client grew 51% to US$10.6 billion, Gaming likewise grew 51% to US$3.9 billion, while Embedded declined 3% to US$3.5 billion.
AI relevance: Instinct accelerators
For AI workloads, AMD offers the Instinct accelerator line (MI series). In the third quarter of 2025, shipments of the new MI350 series (MI350X/MI355X) began to partners and hyperscale data centers; the Data Center segment alone grew 22% to US$4.3 billion that quarter. Customers include Oracle, which according to AMD is building a 27,000-node cluster based on MI355X GPUs and EPYC "Turin" CPUs; other neocloud providers such as Crusoe, DigitalOcean, TensorWave and Vultr have also adopted the MI350 series. Through the 2022 acquisition of Xilinx, completed for an estimated US$50 billion, AMD also expanded its portfolio with FPGAs and adaptive compute solutions for AI and networking applications; in 2024 AMD additionally announced the acquisition of ZT Systems for US$4.9 billion, a provider of custom compute infrastructure for AI workloads.
Client and gaming business
In the consumer segment, AMD sells desktop and mobile processors under the Ryzen brand, built on its Zen architecture (now up to Zen 5), and graphics cards under the Radeon brand's RX series. AMD also supplies custom APUs for game consoles: the PlayStation 5, Xbox Series X/S and Valve's Steam Deck all run on AMD chips, according to Wikipedia — a halo business beyond the PC and the data center.
Business model
AMD is a fabless semiconductor company: it designs chips but has them manufactured externally (predominantly at TSMC). In server CPUs, AMD now holds about 36.5% market share versus Intel's 63.3% (as of July 2025), according to Wikipedia — a marked gain versus earlier years.
A challenger in the AI race
With the Instinct line, AMD positions itself as the leading alternative to market leader Nvidia in the AI-accelerator market, which according to Wikipedia continues to be dominated by a single competitor. Beyond hardware, success also depends on the ROCm software environment, since developers expect mature tools and libraries. US export controls directly affect the business: for the China-specific MI308 chip, AMD booked about US$440 million in 2025 inventory charges, yet still generated roughly US$390 million in Q4 China MI308 revenue. CEO Lisa Su called 2025 "a defining year" for AMD, with record revenue and earnings driven by strong demand for its high-performance and AI platforms. The business remains shaped by product cycles, competition, export restrictions and PC, server and AI demand.
