You can avoid building and operating a Broadcom-based AI system by renting cloud accelerators, using cloud GPU capacity, or commissioning custom or semi-custom infrastructure through another partner. These are different procurement paths, not interchangeable chips: workload fit, software portability, available capacity, networking, and total cost all matter. And choosing another accelerator does not by itself prove Broadcom is absent from the rest of the system.
First define what “without Broadcom” means
Broadcom can be involved in more than accelerator design. A requirement to use a different chip designer is narrower than a requirement to exclude Broadcom from networking, connectivity, or the complete rack supply chain.

OpenAI’s October 13, 2025 announcement says it will design accelerators and systems developed and deployed with Broadcom, and describes Broadcom Ethernet and connectivity in its racks. That example shows why changing the accelerator designer alone is not proof of a Broadcom-free system; it does not establish that every competing provider uses Broadcom. Specify whether your requirement concerns the accelerator, networking components, system integration, or every supplier in the bill of materials, then ask vendors to document the relevant parts and suppliers.

| Route | What you get | Best suited to | Key qualification |
|---|---|---|---|
| Cloud-hosted custom accelerators | Provider-operated systems such as AWS Trainium or Inferentia, Google Cloud TPUs, and Microsoft Maia | Teams that want accelerator capacity without designing and operating a physical cluster | Each accelerator has its own software environment, supported workloads, and access conditions; they are not universal GPU drop-ins. |
| Cloud GPUs or mixed cloud capacity | GPU instances and, depending on provider and service, other accelerator options | Teams with GPU-based tooling or a need to choose among cloud capacity types | Confirm the specific instance, region, capacity, and service status. The cited evidence does not establish a neutral NVIDIA-versus-AMD comparison. |
| Custom or semi-custom infrastructure through another partner | A partner-designed accelerator and rack-scale system, potentially with a specified interconnect ecosystem | Hyperscalers and other organizations with substantial engineering and procurement resources | A partnership announcement is not a ready-made enterprise purchase or a complete disclosure of every supplier. |

AWS Trainium and Inferentia
AWS positions Trainium for training and inference and Inferentia for inference, with access through AWS services and software. AWS also offers GPU infrastructure, so choosing AWS does not require choosing only its custom chips. The AWS infrastructure overview and its August 2026 announcement describe GPU and Trainium paths, including planned integration of NVIDIA NVLink Fusion into next-generation Trainium infrastructure. That announcement does not establish that every instance type is available now in every region.

Google Cloud TPUs
Google describes its TPUs as custom accelerators for training, tuning, and deployment, available as a cloud service. Its materials list support for PyTorch, JAX, and vLLM and describe flexible consumption. Check that the particular model, software path, and capacity fit your workload; framework support does not guarantee that every operator or performance-critical component will transfer without adaptation.

Microsoft Maia
Microsoft announced Maia 200 on January 26, 2026, as an inference accelerator and said it was deployed in the US Central Azure region. The announcement describes an Azure-integrated software and networking stack, but does not by itself establish current customer access or availability for a particular workload. Confirm eligible services, access, capacity, and region with Microsoft before treating Maia as a procurement option.
Microsoft reports 216 GB of HBM3e memory at 7 TB/s and claims 30% better performance per dollar than the latest-generation hardware then in its own fleet. It also claims Maia 200’s FP4 performance is three times that of third-generation Amazon Trainium and its FP8 performance is above Google’s seventh-generation TPU. These are Microsoft’s specifications and comparisons, not independent cross-vendor test results; they should not be generalized to other models, precisions, generations, utilization levels, or workloads.

Use cloud GPUs when flexibility or existing tooling matters
Cloud GPUs are a candidate when your software, kernels, or deployment processes already depend on GPU-based tooling, or when you need a choice of capacity rather than a single provider-specific accelerator. AWS’s published infrastructure material establishes that it offers GPU instances alongside Trainium-based infrastructure. It does not supply a neutral comparison of NVIDIA and AMD hardware, prices, or workload performance, so do not infer a universal GPU winner from it.
Cloud access avoids owning the physical accelerator cluster, but it does not remove the need to check service details. Confirm the exact instance type, region, quota or capacity, networking configuration, and whether the offering is generally available, in preview, or only announced. A provider’s portfolio-level announcement is not proof that a particular configuration can be provisioned for your project.

Commission custom or semi-custom infrastructure only at the right scale
Custom silicon can be a route for organizations whose workload and scale justify shaping an accelerator around specific needs. But the chip is only one part of the project: networking, software, systems integration, deployment, and supply coordination also require investment. The UK Competition and Markets Authority’s 2025 decision discusses cloud-provider self-supply and the software investment required to program custom accelerators. It is useful market-structure context, not a current product-availability guide.
A 2026 NVIDIA and Marvell partnership announcement describes Marvell providing custom XPUs and NVLink Fusion-compatible scale-up networking within a rack-scale platform. This is relevant to hyperscalers or similarly large infrastructure builders that want a custom system aligned with that interconnect ecosystem. The announcement does not make the platform a turnkey consumer or ordinary-enterprise purchase, nor does it disclose every participant in a resulting system’s supply chain.
Evaluate a real workload, not a vendor headline
There is no neutral cross-vendor benchmark or end-to-end cost comparison established here. Vendor performance, efficiency, and cost claims depend on the model, precision, software, utilization, and deployment conditions. Before committing, compare each viable option against a representative workload and document the assumptions behind the result.
Quick Recap
- Workload: Identify whether you need pretraining, fine-tuning, inference, or a mix. Check model size, precision, parallelism, and the accelerator’s intended workload.
- Software portability: Verify framework, operator, compiler, kernel, and inference-engine support. Estimate what must be ported, retuned, or rewritten.
- Network and scale: Check scale-up and scale-out links, collective operations, storage, and cluster topology—not just the accelerator specification.
- Capacity and access: Confirm the required region, service level, capacity, and delivery timing. Distinguish a deployed system or announcement from capacity you can actually use.
- Total cost: Include accelerator time, networking, storage, engineering, migration, and expected utilization. For owned infrastructure, also account for power and cooling.
- Control and location: Decide whether cloud operation is acceptable or whether you need owned or dedicated infrastructure, a specific data location, or more operational control.
- Supply chain: Ask who designs, manufactures, packages, connects, and supplies the accelerator, NICs, switches, optics, and rack system. Match the answer to your exact definition of “without Broadcom.”
A practical way to choose
- Write down the exclusion. State whether you are avoiding Broadcom-designed accelerators, Broadcom networking or connectivity, or any Broadcom component in the system.
- Shortlist by workload. Compare cloud accelerators, cloud GPUs, and custom systems only where the intended training or inference workload and software requirements are a plausible fit.
- Verify provisionability. Get confirmation of the specific product, region, capacity, service status, and deployment timing rather than relying on a general announcement.
- Run a representative evaluation. Use your own model, precision, software path, and expected utilization. Compare useful workload results and the full associated cost, not isolated vendor figures.
- Review the system and contract. For cloud, confirm service and location terms. For a custom build, review software, network, system integration, operational responsibilities, and supply-chain disclosures alongside the chip.
