Because I keep forgetting the specs of the various machines kicking around the house whilst shopping for new toys.

Surprisingly my old Linux box isn’t as under powered as I thought. It just needs some RAM 🙂 But then again the 2020 looks on paper to be the weakest link of the bunch so I guess the old way of counting such things is a bit passé.

EDIT: I added the Geekbench scores and the real story emerges about my tired old PC. Current fast chips are scoring 1400+ (1600 for the ultra high-end ones) and the best Macs are coming in around 1200 (pre-M1).

EDIT 2: (Nov 30, 2021) I added the Geekbench scores for the Pi (the unit that replaced Blackbox — the AMD Athalon) with both standard and overclocked numbers.
