I'm just asking out of curiosity. I definitely don't want to raise the 19BII prices, especially now that my 19BII's battery door latch probably is somewhere in a vacuum cleaner bag...
But I really want to know: Why is the 19BII faster than the 17BII.
The first example is taken from the calculatorstore website:
A=SIGMA(I:1:5000:1:1)
HP 17bII original: 81 seconds
HP 17bII+ gold: 78 seconds
HP 17bII silver:172 seconds
HP 19BII: 73 seconds
Not such a big difference, but anyway...
The second example is from, well, hpmuseum.org and much more surprising:
N-Queens
HP 17BII+: 6m25s
HP 17BII: 3m29s
HP 19BII*: 1m14s
*Using the 17BII solver equation from said web page
How is that possible? Does anybody know? According to HP, the 17BII and the 19BII should be equally fast (15x faster than the 12c).
