AI companies generally do not pick one chip supplier for every job. They match accelerators to workloads—such as model training, inference, or recommendation—and weigh measured performance, software and system fit, total cost, available capacity, and supply resilience. NVIDIA GPUs, custom chips, and Broadcom’s role in building custom silicon are not three interchangeable products: Broadcom is often an implementation and infrastructure partner, while the customer defines the chip and its intended workload.
What are companies actually choosing?
The decision is usually about which accelerator to assign to each workload, not which logo should supply every part of a company’s AI infrastructure. A company may keep general-purpose accelerators for changing or varied tasks and use custom chips for workloads that are stable, recurring, and large enough to justify specialization.

That distinction matters for Broadcom. In the announcements described here, Broadcom works with customers on custom accelerator implementation and infrastructure—including packaging, connectivity, or networking. It is not simply a vendor selling a directly comparable version of NVIDIA’s GPU platform. The customer’s chip design and Broadcom’s role in turning it into a deployable system are related, but not the same thing.
Anthropic offers a clear example of a mixed fleet: it says Claude is trained and run on AWS Trainium, Google TPUs, and NVIDIA GPUs, with workloads matched to suitable chips. Meta likewise describes a “portfolio approach” to matching accelerators to workloads for performance and total cost of ownership.
#1 Best Overall

- OC mode: 2632 MHz (OC mode)/ 2602 MHz (Default mode)
- Powered by the NVIDIA Blackwell architecture and DLSS 4
- Axial-tech fan design features a smaller fan hub that facilitates longer blades and a barrier ring that increases downward air pressure
- A 2.5-slot design maximizes compatibility and cooling efficiency for superior performance in small chassis
How should an AI company evaluate the options?
- Define the workload. Specify whether the target is training, inference, recommendation or ranking, or a mix. Identify the models, serving patterns, scale, and likely workload changes.
- Check software and system fit. Evaluate the full stack, including kernels, compilers, libraries, serving software, scheduling, memory behavior, and networking. A chip specification alone cannot establish application-level performance.
- Measure on the actual workload. Compare throughput and latency under the same workload and system configuration. Depending on the use case, also measure performance per watt, utilization, and cost per completed task or token.
- Calculate total cost and deployment effort. Include more than accelerator purchase or rental cost: account for the surrounding systems, energy, operations, software work, and the cost of adapting workloads.
- Confirm capacity and timing. Distinguish hardware that is available for deployment from capacity that has only been announced or is expected in a future year.
- Assess resilience and supply constraints. Consider whether multiple platforms reduce dependence on one supplier, and whether manufacturing, packaging, memory, or networking could constrain delivery.
Meta CEO Mark Zuckerberg described the company’s stated approach this way: “At Meta, we take a portfolio approach to AI silicon, matching the right accelerator to each workload to achieve the best mix of performance and total cost of ownership.” That is a company’s description of its strategy, not a universal formula or independent performance result.
When can custom AI chips make sense?
An application-specific integrated circuit (ASIC) is designed to optimize a particular workload or class of workloads. The OECD’s 2025 report, Competition in artificial intelligence infrastructure, uses Google TPUs as an example of workload-optimized AI chips. Specialization can be attractive when a company has recurring workloads at sufficient scale to justify designing and integrating a dedicated accelerator.
The trade-off is that the chip must fit the company’s models and software in practice. A custom design can be co-developed around kernels, memory movement, serving patterns, and networking; it is not automatically cheaper, faster, or more efficient than a general-purpose option. The value depends on measured results and the cost of building and operating the complete system.
OpenAI hardware program lead Richard Ho said of Jalapeño: “We optimized the architecture around the kernels, memory movement, networking, and serving patterns that matter most for frontier AI models.” This illustrates the intended co-design approach, but does not by itself establish a performance advantage.

What do the recent company announcements show?
| Company or program | What was announced | Status and qualification |
|---|---|---|
| OpenAI and Broadcom collaboration | Broadcom’s 13 October 2025 announcement described a collaboration for 10 gigawatts of OpenAI-designed AI accelerators. | Broadcom targeted rack deployments beginning in the second half of 2026 and completion by the end of 2029. These were announced plans, not confirmation that deployment had occurred; the timing is forward-looking. |
| OpenAI Jalapeño | On 24 June 2026, OpenAI and Broadcom unveiled Jalapeño, OpenAI’s first “Intelligence Processor,” designed for LLM inference. The companies reported co-developing it from initial design to manufacturing tape-out in nine months. | OpenAI said engineering samples were running workloads in its lab at production target frequency and power, while final performance was still being measured. The nine-month timeline is the companies’ reported project duration, not an independent industry benchmark. OpenAI described Broadcom’s role as silicon implementation and networking support, with Celestica providing board, rack, and system expertise. |
| Meta MTIA | Meta describes MTIA as purpose-built for inference and recommendation at scale. In April 2026, it announced an expanded Broadcom partnership spanning multiple MTIA generations, including chip design, advanced packaging, and networking. | Meta said the first phase of a multi-gigawatt rollout included a commitment exceeding 1 GW. This is an announced commitment, not a comparative performance result. |
| Anthropic compute fleet | Anthropic says it uses AWS Trainium, Google TPUs, and NVIDIA GPUs for Claude, matching workloads to suitable chips. | On 6 April 2026, Anthropic announced an agreement with Google and Broadcom for multiple gigawatts of next-generation TPU capacity expected to come online starting in 2027. That capacity was an expectation, not already-deployed hardware. |
Why is there no universal winner?
The announcements establish that companies are pursuing different mixes of accelerators and custom-chip partnerships. They do not provide a consistent, independent, like-for-like comparison of NVIDIA GPUs and the custom accelerators discussed here across performance, cost per token, or energy efficiency. OpenAI explicitly said Jalapeño’s final performance was still being measured when it unveiled the processor.
Any claim that one approach is faster, more efficient, or cheaper needs to identify the workload, measurement method, date, and system configuration. A result on one model or serving setup does not automatically transfer to another. The OECD report also highlights that AI infrastructure depends on more than chip design: advanced fabrication, packaging, high-bandwidth memory, and other supply-chain stages can affect what can be built and deployed.
How do Broadcom, NVIDIA, and custom chips fit together?
- NVIDIA GPUs: One accelerator option in a company’s broader portfolio. Their suitability should be evaluated against the target workload and the company’s software, system, capacity, and cost requirements.
- Custom AI chips: Accelerators designed around defined workloads. They can make sense when workload scale and stability justify specialization and the required software and system integration.
- Broadcom: A partner in announced custom-silicon programs, supporting implementation and infrastructure work such as packaging, connectivity, and networking. It may help a customer build a custom platform rather than act as the direct alternative to every NVIDIA GPU.
Networking and memory are part of the system, not afterthoughts. OpenAI and Broadcom have described Ethernet and connectivity as elements of planned racks, and OpenAI says Jalapeño’s architecture balances compute, memory, and networking. Consequently, an accelerator comparison that ignores the surrounding rack and data movement can miss important costs and constraints.
