That's an interesting chip. You don't see many bipolar processors. (The Pentium has a few bipolar transistors sprinkled around, but it's mostly CMOS.)

DEC made a one-off ECL CPU in 1993: https://bitsavers.org/pdf/dec/tech_reports/WRL-93-8.pdf

300 MHz / 115 W. Ten years later, you'd have Pentium 4 at 3000 MHz and 115 W.
