Question: AWS Trainium and Google TPU are behind AMD in AI chips?

Answer:

Short answer: not exactly. It depends on which market you mean.

For general-purpose AI accelerator market (merchant GPU market):

NVIDIA CUDA ecosystem
        |
        v
AMD Instinct (MI300X / MI325X / MI355X)
        |
        v
Google TPU / AWS Trainium (mostly internal cloud workloads)

But this ranking is misleading because TPU and Trainium are not trying to compete the same way.

1. NVIDIA / AMD = sell accelerators broadly

NVIDIA and AMD sell hardware to:

hyperscalers
enterprises
AI labs
cloud providers
governments

Example:

OpenAI
  |
  +-- NVIDIA H100/H200/B200
  |
  +-- AMD MI300X (some workloads)

Microsoft Azure
  |
  +-- NVIDIA
  +-- AMD

The key advantage is ecosystem:

CUDA
 |
 +-- PyTorch
 +-- TensorRT
 +-- vLLM
 +-- Triton
 +-- thousands of kernels

2. Google TPU is actually very strong

Google TPU is not “behind AMD” technically.

Google designed TPU because:

Google Search
YouTube
Gemini
Bard
Ads

need massive internal inference/training.

TPU advantages:

custom silicon
optimized for Google’s workloads
huge pod-scale interconnect

Example:

1 TPU Pod

thousands of TPU chips
        |
        |
high-speed interconnect
        |
large distributed model

Google can avoid NVIDIA margins.

But disadvantage:

TPU ecosystem << CUDA ecosystem

You cannot simply take a random PyTorch repo and run it.

3. AWS Trainium is similar

Amazon Web Services Trainium is AWS’s custom AI chip.

The strategy:

AWS customers
       |
       v
EC2 Trn instances
       |
       v
Trainium chips

AWS wants:

reduce NVIDIA dependency
lower AI cloud cost
differentiate AWS

Trainium is especially interesting because AWS already owns:

networking
datacenters
cloud software

The stack:

Neuron SDK
   |
   |
Trainium hardware

But again:

Neuron ecosystem << CUDA ecosystem

4. Revenue comparison is tricky

Your statement:

AWS Trainium 据说收入几十亿百亿美金

The important distinction:

Trainium chip revenue ≠ AWS AI infrastructure revenue.

AWS can make billions from:

AI instances
+
storage
+
network
+
managed services

even if Trainium chip sales are small.

AWS does not sell Trainium like NVIDIA sells GPUs.

5. The interesting part: AI software stack

Your earlier point is actually the deeper one.

The future competition is not only chips:

Layer 7: AI applications
        |
Layer 6: Agents
        |
Layer 5: Agent frameworks
        |
Layer 4: Model serving
        |
Layer 3: Compiler/runtime
        |
Layer 2: Accelerator
        |
Layer 1: Semiconductor

Examples:

Claude Code
    |
    v
OpenClaw
    |
    v
Hermes
    |
    v
Pi agent

This resembles the Linux ecosystem:

Hardware
   |
Kernel
   |
GNU tools
   |
Applications

The winner is not necessarily the best chip.

The winner controls the developer ecosystem.

6. Huawei Ascend comparison

Huawei Ascend is similar:

Ascend chip
 |
CANN
 |
MindSpore
 |
AI applications

The hard part is not only manufacturing silicon.

It is:

developers
+
libraries
+
compiler
+
debugging tools
+
community

CUDA took ~15 years to build.

That is why replacing CUDA is extremely hard.

My view:

By 2030 the market likely looks like:

NVIDIA CUDA ecosystem
        |
        +---- AMD ROCm ecosystem
        |
        +---- Google TPU ecosystem
        |
        +---- AWS Trainium ecosystem
        |
        +---- Huawei Ascend ecosystem
        |
        +---- custom ASICs

NVIDIA may lose monopoly, but the AI market is large enough that multiple trillion-dollar ecosystems can coexist.

The bigger shift is exactly what you mentioned: AI software stacks (agents, compilers, workflows) are becoming as important as hardware. The “CUDA moat” is real, but AI itself is expanding the battlefield.
