At Hot Chips 2026, SK hynix's Jaesik Lee said hybrid bonding won't be ready in time for HBM4E and will instead debut with HBM5, as current HBM4 packages are already constrained by a 775-micron thickness ceiling matching standard logic wafers. To keep scaling within that limit, 16-Hi HBM4 stacks now use dies thinned to about 50 microns with half the interlayer gap of 12-Hi designs, while SK hynix continues using its existing MR-MUF bonding method through upcoming Nvidia Rubin-generation products.
At FMS 2026, Marvell pitched a three-part 'AI memory infrastructure' strategy built around CXL, combining its Structera X memory expansion controllers, the Structera S switch, and the Photonic Fabric optical tier from its Celestial AI acquisition. Only the Bravera SC6 PCIe 6.0 SSD controller, sampling in Q4 2026, is genuinely new; the rest has already been shipping or announced over the past two years, with Marvell VP Khurram Malik highlighting reused DDR4 memory paired with CXL as a top use case.
Amazon has raised prices across its hardware lineup, citing the ongoing memory chip crunch. The Echo Dot jumped 60% to $79.99, while Kindle e-readers, Fire TV streaming devices, and eero mesh routers all saw increases ranging from roughly 13% to nearly 43%. Notably, Amazon's Ring security products were left untouched by the price adjustments.
An engineer spent two weeks pointing an AI coding agent, Claude Opus 5, at the firmware and update tools of everyday USB peripherals—a microphone, a webcam, and a key light. The agent extracted a full command shell from the microphone, found a way to disable the webcam's recording LED while it still captures video, and discovered the key light accepts unauthenticated memory writes from any device on the same WiFi network.
Amazon is currently selling the Asus Prime AMD Radeon RX 9070 OC Edition for $629.99, down 16% from its usual $750 price. The card runs on AMD's RDNA 4 architecture with 16GB of GDDR6 memory, 56 Compute Units, and a factory overclock reaching up to 2,610 MHz boost clock, delivering performance comparable to Nvidia's RTX 4070 Ti Super.
Nvidia has informed top customers that server systems built around its Grace Blackwell and Vera Rubin AI chips will cost more than 15% extra when they ship early next year, according to a Bloomberg report. Contract manufacturers serving Microsoft, Google, and Oracle have already passed along the increases, which vary by chip generation and memory configuration.
