Post-post PC: Materials and Technologies That Could Revive Enthusiast Computing
Dputiger writes "Given the recent emphasis on mobile computing and the difficulty of scaling large cores, it's easy to think that enthusiast computing is dead. Easy — but not necessarily true. There are multiple ways to attack the problem of continued scaling, including new semiconductor materials, specialized co-processor units that implement software applications in silicon, and enhanced cooling techniques to reduce on-die hot spots."
Reality is that "enthusiast" computing today depends on what companies care to provide as "slightly ahead of the current state-of-art" at exorbitant prices. Intel's not going to launch a new CPU for enthusiasts. AMD isn't going to launch a new CPU for enthusiasts. If they do it's just because they can cherry pick some CPUs from their server process (Intel) or that can perform exceptionally well for equally high power consumption (AMD). It is so insignificant to the overall market that progress would happen the same with or without them. We're just not a significant enough portion of the market to really warrant a new process or capacity or whatever.
Live today, because you never know what tomorrow brings
The new semiconductor technology angle in the article seem highly fishy to me. Apart from the fact that the statement felt like it may have said "In 10 years we will all be living in colonies on the moon", III-V materials have been losing market share to silicon for decades.
The article mentions that great electron mobility of the III-V materials, which is true, but forgets to mention that they had poor hole mobility. Now I am not a process expert, so maybe there are new techniques to address this. However, over the past 20 years or so this meant that you couldn't make very good CMOS logic and had to use NMOS only architectures. This and the poor scaling has kept the III-Vs away from large scale integrated logic chips.
The III-V devices were used in RF circuits, but they were replaced by Si-Ge and now many RF circuits use regular silicon processes. The III-Vs are still useful for optics.
The truth is that silicon has many problems that may prevent the industry from continuing to scale circuits to smaller geometries and the available workarounds are generally painful. But, the other options are worse.
Maybe in 10 years we will all be using cell phones that use carbon nanotubes... in our colonies on the moon.
