Because Gary (or someone) had previously posted that the designation is NOT the clock speed but a relative performance index based on many factors of the feature set of the module.
Collapsing multiple dimensions of performance/value down to one arbitrary dimension never works out completely neatly, but it is roughly what they do with car model numbers and appliances and such, so it’s not that weird a concept.
Last time someone did an actual performance comparison, the Cerberus at 168 MHz performed close to the G400, and completely demolished the G120. We must be looking at a lot more than performance here.
Either way, to me, the model numbers are 100% uninteresting. They could call it the G0.75 if they want, it’s still going to be a monster performer.
@ Mr. John Smith - I think the main difference between Cerb and G120/400 is that cerb uses on chip RAM, which is way faster than the external SDRAM of G120 or G400.
So a pure calculation should be faster on G400 than on Cerb. But when it Comes to RAM Access the Cerb can outperform the other boards easily.
An idea: GHI could provide a chart/summary where it compares its mainboards in terms of (1) “pure calculations” done in managed code, (2) RAM access, (3) ethernet max throughput and so on.
