MEMORY / SUPPLYREMARKS JUL 15MAIN STORY

SK Group chairman calls memory prices ‘abnormally high’ and says a U.S. SK hynix plant is under consideration.

Chey Tae-won said DRAM supply must expand to curb ‘chipflation’ hitting PCs and smartphones, while stressing that the possible U.S. fab has not been announced or approved.

Build a $2–$5 ESP32-C3 network ad blocker that keeps 537,000 hashed domains in 4MB of flash.

Flash the MIT-licensed esp32-c3-adblock firmware to a C3 SuperMini and point router DNS at it; the author reports about 50KB RAM and 10ms lookups, while Tom’s says it has not independently seen the device run.

ROBOTICS / DEMODEMO JUL 14MAIN STORY

Tornyol’s 40-gram autonomous micro-drone records its first mid-air insect kill.

The company-reported demo intercepted a moth—not a mosquito—using a 380-microphone phased-array sonar base station and PC control; U.S. reservations require a refundable $100 deposit and the prototype is priced at $1,100.

GMKtec launches a $3,499 EVO-X2 mini PC with 128GB LPDDR5X and 1TB SSD.

Its Ryzen AI Max+ 395 and Radeon 8060S share up to 96GB graphics memory, but doubling RAM from the 64GB/1TB version adds $1,500.

AMD Ryzen 7 7700X3D falls from $329 to $279 at Newegg days after launch.

The eight-core, 16-thread AM5 chip has 104MB combined cache and a 120W TDP; the $279 price requires promo code PKC337 and may change.

CHIPS / MANUFACTURINGEARNINGS JUL 16MAIN STORY

TSMC says A14 test vehicles reached nearly 90% device performance and nearly 90% 256Mb SRAM yield.

The 1.4nm-class node remains targeted for H2 2028 volume production and is designed for 10–15% more speed or 25–30% less power than N2; the reported yield is for an SRAM test structure, not a commercial processor.

One Shark vacuum certificate could remotely execute root commands on at least 673,816 other devices in the same AWS region.

The researcher demonstrated cross-model code execution, camera access, motor control, home-map access and plaintext Wi-Fi credentials; the flaw was still unpatched when July 17 coverage appeared.

NETGEAR publishes fixes for five router and access-point flaws and tells DGND3700v1 owners to replace the unsupported model.

A certificate-validation flaw affecting MR70, MS70, RAXE500 and XR1000 could allow remote takeover; firmware fixes also cover Orbi, RAX and WAX333 models.

WEARABLE ROBOTICS

Intel says FREE Walk exoskeleton has logged 40,000 patient training records across 22 countries.

The wearable combines Core Ultra, OpenVINO, EMG, pressure and inertial sensors for local gait inference; deployment and staffing figures are company claims, not an independent outcomes study.

MEMORY / PRICING

Memory capacity is becoming a product gate.

SK’s price warning, the $1,500 64GB-to-128GB premium on GMKtec’s mini PC and the RTX report all point to memory—not compute silicon—setting consumer-hardware price and launch timing.

PROCESS / CAVEAT

Advanced-node numbers need the test-structure caveat.

TSMC’s near-90% figure is a 256Mb SRAM test-chip yield, not finished-CPU yield; A14 volume production is still targeted for H2 2028.

CONNECTED DEVICES

Device identity and update support are hardware features.

The Shark disclosure and NETGEAR advisory show how device-scoped cloud certificates, patchable firmware and an active support window determine whether connected hardware remains safe.

Report: Nvidia has told board partners to hold RTX 50 Super cards over 3GB GDDR7 pricing.

VideoCardz cites one unnamed partner saying cards are physically available but on hold, with 3GB modules quoted at $60–$70 versus about $20 for 2GB; Nvidia has not confirmed the lineup, timing or prices.

Leaked 10-core AMD ‘Medusa Point’ engineering sample posts 3,329 single-core and 16,555 multi-core in Geekbench.

The result is roughly 5% and 9.7% above the same sample’s prior run, but an unverified engineering-sample listing cannot establish final clocks, power or retail performance.
