Benchmarks 71B versus 48GX

On the HP48 series, taking the HP48G/G+/GX as an example, the clock speed is derived from the aforementioned HFO divided by 2. AFAIK, the nominal clock speed is around either ~3.93MHz or ~3.67MHz, but, due to reasons I've already mentioned, can vary to a non-negligible degree. I have several HP48GXs that have ~3.9MHz+ clock speeds, and, it seems to me that the "nominal" clock speed is around a little below ~4MHz for these. Also, these calculators are *not* "very early" models ( I've measured ~3.9MHz+ clock speeds on HP48GXs manufactured in Singapore, China and Indonesia )

I can confirm that, my HP-48GX is from the latest ones, SN ID30700327 and always reports abt 3.933MHz
