Silicon performance scales as a direct function of temperature. Cutting the temperature in half will double performance. Thing is, you have to measure the temp in Kelvin. Cutting the temp from 50C to 25C won't buy you quite 10% in performance, which would equate roughly to the 2-3% for 10C that you quote above. Cutting the temp from 50C to -20C means going from 323K to 253K, which is almost a 25% reduction in temp. Indeed, on average, we see that systems cooled by phase-change to these temps do indeed increase in performance by about 25% (sometimes more), over what was achievable with air cooling alone.
