The machine, made understandable.

Meet the machine.
Understand every layer.

From a single transistor to a billion operations. Open the chip, move the data, and see what your code is really asking the hardware to do.

Pick a component. Look inside.
The decision maker

Predict, decode, schedule, execute. A few powerful cores handle complex, sequential work.

THE BUILDING BLOCKS

One system. Many worlds inside.

CHANGE ONE THING.

What happens if you change one thing?

Break a cache. Split a warp. Turn up the clock. Nine small labs make the invisible visible.

Enter the lab
FOLLOW YOUR CURIOSITY

Good questions lead to better code.

Why can RAM slow down a fast CPU?

Data movement

Are a thousand GPU cores better than eight CPU cores?

Architecture, not numbers

What is a “super core”, really?

Beyond the product names

CONCEPTS

Transistors & CMOSA tiny voltage-controlled switch. Billions of them become a computer.
Anatomy of a CPU coreA core is a complete instruction engine, not just an arithmetic unit.
Anatomy of a GPUMany execution lanes share control machinery to process parallel work.
Inside DRAMA capacitor holds a bit. A controller keeps billions of them readable.
NPUs & neural enginesDedicated data paths turn repeated tensor operations into efficient hardware work.
SoCs, chiplets & packagesA system is more than a CPU. Integration changes how its parts communicate.
Logic gates & Boolean algebraSimple truth tables become selectors, adders, and control circuits.
Bits, integers & floating pointThe same bits can represent a number, an instruction, or a color.
Clocks, flip-flops & stateA clock separates what a circuit remembers from what it computes next.
ISA, microarchitecture & ABIThe instruction contract, its implementation, and the rules for calling code.
From source to machine codeYour code becomes data flow, instructions, and a contract with the runtime.
Pipelines & instruction hazardsOverlap stages of different instructions instead of finishing one at a time.
