John Carmack suspicious of Nvidia’s outlandish Tegra K1 claims
Joel Hruska
ExtremeTech, February 20, 2014
When Nvidia unveiled the Tegra K1 last month, they made a great many impressive claims about its performance, underlying architecture, and the fact that it would debut as two different parts -- a quad-core based on the Cortex-A15r3 with the now-standard Companion Core for added energy efficiency, and a dual-core 64-bit chip that supports ARM’s 64-bit instruction set. John Carmack himself has just tossed water on these claims, telling people that Nvidia’s statements should be taken “with several grains of salt.”

Hybrid Memory Cube 160GB/sec RAM starts shipping: Is this the technology that finally kills DDR RAM?
Joel Hruska
ExtremeTech, September 25, 2013
Micron announced today that it’s now shipping early samples of its Hybrid Memory Cube to customers and early adopters. Currently the company is offering a 2GB HMC device composed of four-high stacks of 4Gbit memory dies, with a total bandwidth of 160GB/s for the 31 × 31 mm package. There’s also a smaller chip, at 16 × 19.5 mm, that offers two links instead of four and tops out at 120GB/s. A 4GB device is scheduled for early 2014, which could hit up to 320GB/s depending on the final implementation.

New LIDAR chip will sharpen aerial mapping and autonomous car vision
Ryan Whitwam
ExtremeTech, February 18, 2014
Handheld laser rangefinders have been available to consumers for years, but increasingly powerful military and industrial versions of the technology are still being developed. A new breed of LIDAR (light detection and ranging) technology is being developed and tested by the US Air Force at a base in Massachusetts. This system is capable of precisely mapping over 300 square kilometers from the belly of an airplane in about half an hour.
