xAI has launched Grok 4. It might be the most powerful AI ever made.
But there’s a hidden story behind it. A key reason Grok 4 works so well is because of TSMC, the world’s top chip maker. They built a new way to package chips called “System on Wafer” or SoW. It helped Musk go beyond the limits of regular computer systems.
This is a full reset in how computers are built for AI.
Why This Matters
Today’s AI models need way more computing power than just a few years ago. Grok 4 needed something better than standard GPUs. That’s why Musk and TSMC worked together to create a different kind of supercomputer.
The result is Dojo 2, a custom-built system that uses TSMC’s SoW tech. It connects a full wafer of chips into one powerful unit. This is far more advanced than the usual chip stacking methods.
Here’s what makes it powerful
- One wafer holds 25 D1 chip units
- That’s 50 billion transistors working together
- Each chip can do 362 trillion operations per second
- One full system can deliver 9 Petaflops of compute power
This design is about 5 times more powerful than older technologies like CoWoS, which are used in other big AI setups.
Why Grok Needed This
As AI keeps growing, old hardware can’t keep up. Big GPUs hit limits in size and speed. When too many chips are connected, they slow down due to heat and delay. Dojo avoids all that by treating the whole wafer as one large chip. That means faster results, lower delay, and huge savings on energy.
What’s Next
Dojo 2 is expected to go into full production by the end of 2025.
TSMC is also working on the next version, called SoW-X. It will include even more powerful chips and advanced memory systems. It may be ready by 2027. This version will need advanced cooling systems like liquid or immersion cooling because of the heat it creates.
For Investors and Fans
This is about Tesla and xAI building the future of computing. Grok 4 shows what’s possible when hardware and software are built together from the ground up. This kind of tech will power Robotaxis, Full Self-Driving, and more.
TSMC’s SoW tech gave Grok 4 the power it needed. Elon Musk saw the future and built a system strong enough to handle it.
And this is just the beginning.
