Ten flagship chips
Supplier Rings for Ten Flagship Chips
Each supplier ring follows one chip through its logic dies, memory, interposer, substrate, packaging and test, naming the plant and whether it is in the United States.
| Chip | Designer | Logic die | Memory | Package | Ring |
|---|---|---|---|---|---|
| NVIDIA Blackwell Ultra (B300) | NVIDIA | TSMC 4NP | 288GB HBM3E | TSMC CoWoS-L | Supplier ring |
| NVIDIA Rubin | NVIDIA | TSMC N3P | 288GB HBM4 | TSMC CoWoS-L | Supplier ring |
| AMD Instinct MI455X | AMD | TSMC N2 and N3 | 432GB HBM4 | CoWoS-L with hybrid bonding | Supplier ring |
| Google TPU Ironwood | Google with Broadcom | TSMC; node not disclosed | 192GB HBM3E | Placeholder | Supplier ring |
| AWS Trainium3 | AWS (Annapurna Labs) | 3nm, reported TSMC | 144GB HBM3E | Placeholder | Supplier ring |
| Microsoft Maia 200 | Microsoft | TSMC 3nm | 216GB HBM3E | Placeholder | Supplier ring |
| Tesla AI5 | Tesla | TSMC (Arizona) and Samsung (Taylor) | Placeholder | Placeholder | Supplier ring |
| Huawei Ascend 910C | HiSilicon | SMIC 7nm class; TSMC-made dies found in teardown | HBM2E, stockpiled Samsung and SK hynix | Placeholder | Supplier ring |
| SK hynix HBM4 | SK hynix | SK hynix 1b DRAM; TSMC 12nm-class base die | 12-high HBM4 stack | SK hynix MR-MUF | Supplier ring |
| Apple A19 Pro | Apple | TSMC N3P | 12GB LPDDR5X | TSMC InFO | Supplier ring |
The rack-scale rings on DatacentersX stop at the accelerator; these rings open it. All ten are on Chip Supplier Rings. How each accelerator sets the power of its rack, from about 135 kW for a GB300 NVL72 to about 190 to 230 kW for Vera Rubin NVL72 and 225 to 245 kW for AMD Helios, is on the DatacentersX AI Chip Layer page.
Hyperscaler chips
Hyperscalers Build Chips for Their Own Clouds
- Google: TPU Ironwood, designed with Broadcom, carries 192GB of HBM3E and scales to 9,216 chips per pod. Anthropic plans to use up to a million TPUs.
- AWS: Trainium3, its first 3nm chip, has 144GB of HBM3E and went into general availability in December 2025 in UltraServers of up to 144 chips.
- Microsoft: Maia 200, on TSMC 3nm with 216GB of HBM3E, began rolling out in Azure's US Central region in January 2026.
- Meta: MTIA runs ranking and recommendation inference, designed with Broadcom.
- Tesla: AI5 is made at both TSMC and Samsung, with vehicle volume reported for 2027.
These chips are not sold on the open market, so their wafers never show up in GPU shipment figures, yet they draw on the same TSMC wafers, CoWoS lines and HBM as NVIDIA and AMD. Broadcom, which designs custom chips for Google, Meta and others, reported $16.7 billion of AI semiconductor revenue in its fiscal third quarter of 2026, up 221% in a year.
Other accelerators
Startups and Chinese Accelerators
| Family | Products | Process | How it is sold |
|---|---|---|---|
| Meta MTIA | MTIA for ranking and recommendation inference | TSMC 5nm class | Captive, Meta's own data centers; designed with Broadcom |
| Cerebras | WSE-3 wafer-scale engine in CS-3 systems | TSMC 5nm, one chip per 300mm wafer | Sold as systems and cloud service; national labs and inference customers |
| Groq | LPU inference chips | GlobalFoundries 14nm (first generation) | Cloud inference service |
| Tenstorrent | Wormhole and Blackhole, RISC-V and Tensix cores | TSMC 12nm (Wormhole), TSMC 6nm (Blackhole) | Cards and systems; open-source software |
| SambaNova | SN40L reconfigurable dataflow unit | TSMC 5nm | Systems and cloud for government and enterprise |
| Cambricon | Siyuan accelerators | SMIC and other Chinese foundries | Chinese cloud and AI companies; revenue about $890 million in the first half of 2026 |
| Huawei Ascend roadmap | Ascend 950 and later, with Huawei's own HBM | SMIC | Huawei Atlas systems; Huawei reportedly aims to double Ascend output in 2026 |
| Baidu, Alibaba | Kunlun P800; T-Head accelerators | Chinese foundries | Captive, own clouds |
Bottlenecks
AI Accelerator Bottlenecks
| Bottleneck | Affects | Severity |
|---|---|---|
| TSMC leading-edge wafers | Every hyperscaler accelerator plus NVIDIA and AMD GPUs | Critical: one wafer pool for all of them |
| CoWoS and HBM | Every accelerator with HBM | High: same packaging and memory as GPUs |
| Design partners | Google, Meta and OpenAI with Broadcom; others with Marvell, Alchip, GUC and MediaTek | Medium: a small set of firms can take a hyperscaler chip to tape-out |
| CUDA switching cost | Merchant accelerators selling to outside customers | High for adoption, not for supply |
| Export controls | Huawei, Cambricon and other Chinese accelerators | High: no TSMC leading edge, limited HBM, no EUV |
