“You’re going to buy a 10-way, 18-way multi-core processor that’s the latest, all because we told you you could buy it and made it available, and we’re going to turn some of those processors off most of the time,” Wilson said. “So you’re going to pay for logic and we’re going to turn it off so you can’t use it.”
Or in otherwords,
“This is sort of the end of Moore’s Law,” Wilson said.
Intel officials have argued that Moore’s Law will continue to be viable into the forseeable future, but Wilson and others say the end is in sight. Wilson said the tipping point is at the 28nm level. After that, more gates might be added, but utilization is reduced. At the same time, the cost per gate – which had steadily declined until 28nm – begins to increase as the chips get smaller, and while there will still be processors made on the 16/14nm and 22/20nm processors, their use will stay stagnant or decline between now and 2025, Wilson said. Meanwhile, the use of 28nm processors will increase.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound.
