    IBM Announces New Processor Breaktrhrough

    IBM says it has created the world's smallest and most powerful microchip

    New York (CNN Business)The semiconductor industry's constant challenge is to make microchips that are smaller, faster, more powerful and more energy efficient — simultaneously.
    On Thursday, IBM (IBM) announced it has created a 2-nanometer chip, the smallest, most powerful microchip yet developed

    Wow that's a big jump in nanometers!

    Not really a huge step. The "nanometers" have nothing to do with actual dimensions anymore (they used to, but semiconductor manufacturers started exaggerating their numbers until they became just a naming convention for each manufacturer's process generation). What's important is transistor density. IBM's chip has about 333 million transistors per square millimeter; currently the best process in use is about 170 million.

    So this is about twice as dense as the best chips in production. But it's not itself in production, it's a research project. You can bet that what Intel, Samsung or TSMC has in their labs isn't far behind.

    I'm old enough to remember the mid-1970's when the San Jose Mercury-News sent a photographer out for a picture of a large cabinet. That single cabinet had a whopping 8 Megabytes of high-speed memory inside; this had never been done before. (IIRC each memory bit used three transistors.)

    I prefer prophylactics.

    It's not nearly as effective as being a semiconductor nerd, IBM research shows. The development of the 2nm microchip reduced chances of sexually transmitted diseases by 150% more than wearing a condom.

    Smaller features means more transistors and more chips per blank wafer meaning lower cost per chip. 'Die SAhrink'.

    Even without adding more capability periodic die shrinks lowered cost.

    Increasing speed while minimizing power is an accomplishment. That is always the goal.

    Not necessarily. Shrinking the transistors usually means higher error rate (at least in the beginning), which leads to smaller number of working chips per wafer which drives up the cost. Intel in particular has been struggling with this, which is one of the reasons AMD has been able to pull ahead in recent years.

    When I was around it processes were rated in defects per unit area of the wafer. Defects on the wafer and contamination like airborne particles. Shrink the die in oen sense increases quantity oher things being equal.

    There were occasional problems with shrunk chips in production. Sometimes they did not meet performance specs of the earlier part and specs were changed causing user manufacturing problems. In one case we had to search for older parts to keep a product going.

    I was a systems reliability engineer at Intel in Hillsborough Or in the 80s. I was involved in chip failure analysis with failures during reliability tests.

    What’s the big deal? Bill Gates has already made microchips small enough to fit in a vaccine!
