EUV Lithography Explained: The Hardest Machine on Earth
One company builds the machines that print every advanced chip. Inside EUV: tin plasma, atomically smooth mirrors, $400 million price tags and the export controls built around them.
HBM and the Memory Wall: AI’s Real Hardware Bottleneck
AI accelerators spend most of their time waiting for memory, not doing math. Here is how HBM stacking works, what HBM4 actually delivers, and why DRAM prices are climbing.
ARM vs x86 vs RISC-V: The CPU Architecture War Explained
Three instruction sets now compete for every chip built. The real differences are licensing, ecosystems and emulation, not whether the instructions are reduced or complex.
The 2nm Era: What Gate-All-Around Transistors Change
TSMC's N2 process replaced the FinFET with stacked nanosheet transistors. Here are the verified performance numbers, the $30,000 wafer, and how Intel and Samsung compare.
Inside an AI Data Center: Racks, Power, Cooling, Water
One GPU rack now holds 72 accelerators, 13.4TB of memory and a copper spine that must be liquid-cooled. Here is what that changed about the building around it.
