You're kind of correct. Current state of the art commercial SiGe BiCMOS technologies only give 200 GHz, so if those grad students got 375 GHz in their lab experiments, it would be a nice advance when commercialized. Exactly on the speed trend for such devices by the way, so presumably several other players will have comparable results soon. These are very expensive transistor fabrication processes, and are economic only for relatively small circuits like radio receivers. They are low-power in the sense that compared to traditional Bipolar they consume much less, but that's not even close to CMOS. If you tried to use this technology for the 100-500M transistors in a Pentium, it would probably consume 2000 Watts, cost $50 million per chip, and have almost zero yield. (A long while ago, Bernie Meyerson was in the next office to me at IBM Research. All I knew about him was he was incredibly annoying... whistled loudly all the time. I later learned he was doing world-changing research on chemical vapor deposition of Ge onto Si i.e. the very technology that this press release is about. Personally I still don't think it justified the whistling.)
