apple a20 pro dram iphone chip memory tsmc shortage

Apple's A20 Pro production is going smoothly, except DRAM supply is bottlenecking iPhone assembly

TSMC is sitting on $1 billion worth of finished iPhone chips with nowhere to go
Ripple effect: In the run-up to the launch of the foldable iPhone Ultra, iPhone 18, and iPhone 18 Pro, Apple and its assemblers are working to secure enough mobile DRAM. Apple leans heavily on Micron for these chips and also buys from SK Hynix and Samsung. People involved say they still expect to meet initial demand, but they worry online wait times could stretch and store inventory could run out quickly if the shortage continues.

AMD's Zen 6 Epyc chip packs 256 cores, promises up to 1.7x faster AI

It also provides a glimpse of the architecture that will power future Ryzen chips
First look: AMD will give its first public look at Epyc Venice CPUs this month, showcasing the new Zen 6 architecture at the Advancing AI 2026 summit in San Francisco on July 22. The demonstration will highlight performance for AI workloads, with AMD claiming a major speed increase over current Epyc chips.

Nvidia RTX Spark CPU is now official: "superchip" will power Windows laptops and desktops

Nvidia wants to make your Windows PC an agentic and creator powerhouse
Why it matters: Nvidia just announced what it calls the most efficient PC chip ever built. RTX Spark is a Grace Blackwell system on a chip, 70 billion transistors on TSMC 3nm, with a Blackwell RTX GPU, a 20-core Arm CPU built with MediaTek, and up to 128GB of unified memory. It is purpose-built for agents, and it runs full RTX gaming and creation on the same thin-and-light laptop. It is a genuinely impressive piece of silicon.
researchers performance chip research 3d graphics moores law transistor yields

Moore's law is hitting a wall, so researchers are stacking silicon chip layers instead of shrinking them

University of Illinois team stacks three active silicon layers on a single chip, achieving 98-100% transistor yield
Forward-looking: For years, the chip industry has chased better performance by shrinking transistors and squeezing more of them onto a flat slice of silicon. That strategy is running into hard limits. A group at the University of Illinois thinks the next gains will come not from going smaller, but from going vertical.
