Apple Reorganizes Hardware Into Five Silicon-Focused Divisions… Apple is entering one of the most consequential transitions in its modern history. As the company prepares for John Ternus to become chief executive officer on September 1, 2026, it is simultaneously reshaping the organization responsible for one of its greatest competitive advantages: hardware and custom silicon. The centerpiece of that change is a new structure under Johny Srouji, Apple’s longtime silicon chief, who has been appointed chief hardware officer and given responsibility for a unified hardware organization.
Reports based on an internal memo from Srouji say the combined hardware engineering and hardware technologies organization will be arranged primarily around five areas: hardware engineering, silicon, advanced technologies, platform architecture, and project management. The leaders named for those areas are Tom Marieb, Sri Santhanam, Zongjian Chen, Tim Millet, and Donny Nordhues, respectively.
The phrase “five silicon-focused divisions” can therefore be misleading if interpreted literally. Apple is not creating five separate chip divisions. Rather, it is creating a five-part hardware organization in which silicon becomes one of the central pillars alongside the physical engineering, emerging technology, architecture, and execution disciplines required to turn chips into finished products.
That distinction matters. Apple’s custom silicon strategy has evolved from being primarily about replacing third-party processors into a much broader philosophy of vertical integration. Today, the processor is only one component of a system that can include graphics, machine learning accelerators, memory architecture, image processing, security, connectivity, power management, displays, sensors, and software optimization.
The new organization appears designed to make those pieces work more closely together at a time when Apple faces an increasingly demanding technology landscape dominated by artificial intelligence, increasingly sophisticated devices, semiconductor constraints, and intense competition in smartphones, PCs, wearables, and emerging computing categories.
The restructuring follows Apple’s April 2026 announcement that John Ternus will succeed Tim Cook as CEO. Ternus, previously senior vice president of Hardware Engineering, is scheduled to take over on September 1, while Cook will become executive chairman. Apple said the transition was unanimously approved by its board and described it as the result of long-term succession planning.
At almost the same time, Apple announced that Johny Srouji would become chief hardware officer. He will oversee the former Hardware Engineering organization in addition to the Hardware Technologies organization that he had already led. Apple said Srouji would bring the two groups together under a broader hardware structure.
The resulting five areas are:
Bloomberg’s reporting, subsequently summarized by several technology publications, described the purpose of the change as simplifying Srouji’s organization while bringing thousands of additional employees and product-engineering responsibilities under his oversight.
Apple’s silicon story did not begin with the M-series chips. The company spent more than a decade developing its own system-on-chip capabilities for products such as the iPhone, iPad, and Apple Watch before bringing the same philosophy to the Mac.
When Apple announced its Mac transition to custom silicon in 2020, it explicitly described the move as a way to establish a common architecture across its products. Apple argued that a shared architecture would make it easier for developers to optimize applications across the ecosystem while allowing the company to control performance, efficiency, and specialized technologies more closely.
The first M1 Macs arrived later that year. Apple said the M1 delivered up to 3.5 times faster CPU performance, up to six times faster GPU performance, up to 15 times faster machine-learning performance, and up to twice the battery life of the previous-generation Macs in its stated comparisons. The chip contained 16 billion transistors and was manufactured using a 5-nanometer process.
The significance was larger than a benchmark victory. Apple was effectively demonstrating that it could design the central computing architecture of several product categories around its own priorities instead of adapting its products to processors designed primarily for a broader PC market.
Johny Srouji is particularly important to understanding why the current restructuring is so significant. Apple says Srouji joined the company in 2008 to lead development of the A4, its first internally designed system-on-chip. Before Apple, he held senior processor-development and design roles at Intel and IBM.
Over time, Apple’s chips evolved from application processors into increasingly comprehensive systems. CPU cores, GPUs, neural-processing capabilities, image processors, secure enclaves, media engines, memory controllers, and other specialized components became integrated into Apple’s silicon strategy.
The M-series then extended this approach into laptops and desktops. Rather than maintaining completely separate technological foundations for mobile and Mac products, Apple could increasingly share architectural concepts and development expertise across categories.
This creates several strategic advantages:
That is why a reorganization centered on silicon is potentially much more consequential than an ordinary management reshuffle.
The most interesting feature of Srouji’s structure is that it does not isolate silicon from the rest of hardware development. Instead, it places silicon, hardware engineering, architecture, advanced technology, and project execution within one overarching organization.
This could address one of the hardest problems in advanced consumer electronics: optimization across boundaries.
A processor cannot be evaluated independently from the thermal design of a laptop. A camera system cannot be optimized independently from image-processing silicon. A wearable’s battery life depends on its processor, display, sensors, wireless systems, operating system, and software behavior. An AI feature depends not just on a model, but also on memory bandwidth, accelerators, privacy architecture, power consumption, and the device’s ability to process information locally.
Bringing these disciplines closer together could allow Apple to make more aggressive system-level trade-offs.
Hardware engineering remains the physical foundation. It encompasses the difficult work of turning ambitious designs into devices that can be manufactured reliably and at enormous scale.
Apple’s product portfolio spans smartphones, tablets, computers, watches, headphones, spatial-computing devices and accessories. Each has different constraints involving materials, thermal management, battery capacity, reliability, repairability, manufacturing, and component integration.
The hardware engineering group therefore provides the bridge between silicon ambition and physical reality.
The silicon division may be the most strategically visible of the five. Its responsibility across Apple’s product portfolio suggests that the company wants its chip road maps to be coordinated rather than developed as isolated projects.
This is particularly important as AI becomes a standard part of consumer devices.
Apple’s M5 generation provides a useful example. Introduced in 2025, M5 used a third-generation 3-nanometer process and incorporated Neural Accelerators into each GPU core. Apple reported more than four times the peak GPU AI compute performance of M4, along with a 16-core Neural Engine and memory bandwidth of up to 153GB per second.
These specifications illustrate how modern chips are no longer simply about faster CPU cores. AI workloads require specialized computational resources, and Apple’s response is to integrate those resources directly into its silicon architecture.
The advanced technologies group may be especially important for Apple’s longer-term ambitions. Companies that compete successfully in consumer technology cannot wait until a new product category becomes commercially obvious before beginning research.
Technologies such as advanced displays, sensing, wireless systems, artificial intelligence, new materials, battery technologies, cameras, and spatial computing can require years of research before appearing in a shipping product.
A dedicated advanced-technology organization gives Apple a mechanism for pursuing these technologies while the main product teams remain focused on delivering current generations of devices.
Platform architecture is the discipline that can turn individual components into coherent computing systems. It asks questions such as how processors, memory, operating systems, accelerators, security technologies, connectivity, and application frameworks should work together.
This role becomes increasingly important as Apple tries to create common technological foundations across iPhone, iPad, Mac, Apple Watch, Vision Pro, and future products.
Apple itself emphasized this concept when it introduced the Mac transition to Apple silicon, arguing that a common architecture could make software development and optimization easier across its ecosystem.
Even the best chip architecture is irrelevant if a product misses its launch window, cannot be manufactured at scale, or requires last-minute compromises.
Project management therefore becomes strategically important in an organization handling thousands of engineers and multiple product road maps. Coordination between silicon development and physical product development is particularly difficult because chip projects can take years and have highly inflexible production schedules.
Strengthening this function could help Apple synchronize engineering milestones with manufacturing and product launches.
The M5 provides a useful example of the direction Apple appears to be pursuing. The chip is not confined to a single device category. Apple introduced M5 for MacBook Pro, iPad Pro, and Apple Vision Pro, demonstrating how a silicon platform can span substantially different products.
The Vision Pro case is especially revealing. Spatial computing requires substantial graphics performance, machine learning, display processing, sensor processing, and power management. Apple upgraded Vision Pro with M5 in 2025, highlighting improvements in rendering, AI-powered workflows, and battery life.
This demonstrates why Apple increasingly needs hardware teams to think beyond individual components. The competitive advantage comes from the interaction between the components.
Artificial intelligence is changing what customers expect from personal devices. AI assistants, image generation, speech recognition, translation, summarization, productivity tools, and personalized experiences all require substantial computation.
Apple has a particularly strong incentive to perform more AI processing on devices because local processing can improve responsiveness and privacy while reducing dependence on cloud infrastructure.
That makes silicon architecture strategically important. An AI-capable device needs the right combination of CPU performance, GPU acceleration, neural processing, memory capacity, memory bandwidth, power efficiency, and software frameworks.
The M5 architecture illustrates this direction. Apple specifically emphasized its Neural Accelerators, faster Neural Engine, increased memory bandwidth, and improved GPU AI performance.
A unified hardware organization could allow Apple to make AI a system-level design requirement from the beginning rather than adding AI capabilities after the core hardware has already been defined.
The timing is difficult to ignore. John Ternus is moving from hardware leadership to the CEO position, while Srouji is expanding from leading hardware technologies to overseeing the broader hardware organization.
Apple’s official announcement describes Ternus as having deep technical knowledge and extensive experience with the company’s hardware products. The company also highlighted his involvement in reliability, durability, materials, design, and manufacturing-related innovations.
That creates a leadership structure with unusually deep hardware expertise at the top of Apple.
It does not mean Apple is abandoning the operational strengths developed during Cook’s tenure. Apple says its revenue grew from $108 billion in fiscal 2011 to more than $416 billion in fiscal 2025, while its active installed base has grown beyond 2.5 billion devices.
Instead, the shift may indicate that the next phase of Apple’s growth requires a different organizational emphasis: deeper control over technology, faster integration of hardware and silicon, and new product experiences built around increasingly sophisticated computing architectures.
Apple’s silicon strategy cannot be separated from semiconductor manufacturing. In July 2026, Apple announced a multiyear agreement with Broadcom expected to exceed $30 billion for custom silicon components and advanced wireless connectivity technologies. Apple said the agreement is expected to support production of more than 15 billion chips in the United States and includes a $1.5 billion capital expenditure commitment by Broadcom for facilities in Fort Collins, Colorado.
This is significant because designing chips and securing the ability to manufacture them at scale are two sides of the same strategic problem.
Apple does not manufacture every chip itself. It works with manufacturing partners and suppliers. But greater control over chip design allows Apple to determine what it wants manufactured, while broader supply-chain investments can help reduce exposure to manufacturing concentration and geopolitical disruption.
The five-part hardware organization therefore sits inside a much larger strategy involving architecture, engineering, manufacturing, supply chains, and product development.
If executed effectively, the reorganization could give Apple several advantages.
Reorganizations are not automatically beneficial. Combining large engineering organizations can create new layers of management, competing priorities, communication challenges, and internal bureaucracy.
There is also a potential risk that centralizing hardware under one leader could make the organization too large. Apple is famous for functional specialization and tightly controlled product development. A broader hardware organization must preserve that focus without becoming slow.
Another challenge is balancing shared platforms with product-specific innovation. A common chip architecture can create enormous efficiency, but the needs of a watch are fundamentally different from those of a MacBook or spatial-computing headset.
Apple will therefore have to maintain a delicate balance: centralize the technology foundations while allowing individual product teams enough freedom to create differentiated experiences.
It is too early to say that the new structure guarantees specific products or launch dates. However, it provides clues about the kinds of engineering priorities Apple may emphasize.
Future devices are likely to depend more heavily on custom silicon and system-level integration. That could include:
The most important change may therefore be invisible to customers. Rather than noticing a new organizational chart, consumers may eventually experience the consequences through longer battery life, faster AI features, better cameras, improved graphics, more capable applications, and devices that can perform increasingly complex tasks locally.
Apple’s advantage is not simply that it designs chips. Many technology companies design processors or specialized silicon. The harder-to-replicate advantage comes from controlling multiple layers simultaneously.
Apple controls the operating systems, develops key frameworks, designs much of the silicon, controls product architecture, designs the physical devices, and manages a massive ecosystem of applications and services.
This vertical integration creates a feedback loop:
The five-part hardware structure appears compatible with this philosophy because it brings many of these disciplines into a single leadership framework.
Apple’s decision to bring Hardware Engineering and Hardware Technologies together under Johny Srouji is more than a routine management adjustment. It reflects how important custom silicon has become to the company’s identity and competitive strategy.
The five-part structure—hardware engineering, silicon, advanced technologies, platform architecture, and project management—recognizes that modern devices are no longer collections of independently optimized components. They are integrated computing systems in which processors, AI accelerators, software, sensors, displays, batteries, wireless technologies, and physical design must work together.
The timing is equally important. The restructuring arrives alongside John Ternus’s transition to CEO and at a moment when AI is changing the definition of personal computing. Apple’s M-series evolution, from the M1’s 2020 debut to the AI-focused M5 generation, demonstrates how quickly custom silicon has moved from a technical differentiator to a foundation of the company’s product strategy.
The biggest opportunity for Apple is therefore not simply producing faster chips. It is using organizational integration to design entirely new experiences around those chips. If silicon engineers, hardware designers, platform architects, advanced-technology researchers, and program managers can operate with greater coordination, Apple could shorten the distance between technological breakthrough and finished product.
There are risks, particularly the possibility that a larger centralized organization becomes slower or less flexible. But Apple’s broader trajectory suggests that it believes the benefits of deeper integration outweigh those risks.
The clearest takeaway is that Apple is increasingly treating silicon as the foundation around which its hardware future is built. The company is not merely designing processors for existing products; it is building a technology architecture that can shape what those products are capable of becoming.
