15 "Intel Atom" cpu chips fit on a penny and if one is used in a future
desktop the chip uses about 3 watts hopefully with no noisy fan kicking
on/off like my present Dell 2.8ghz when its asked to number-crunch for
several minutes.
15 "Intel Atom" cpu chips fit on a penny and if one is used in a future
desktop the chip uses about 3 watts hopefully with no noisy fan kicking
on/off like my present Dell 2.8ghz when its asked to number-crunch for
several minutes.
However the Atom runs at 1.6ghz and the only benchmark I have seen shows it
under-crunching my beloved old 900mhz Celeron, which ran quiet so I'm not
sure I can use it as a replacement for my Dell 2.8ghz.
Q.
Can anyone find confirmation that a Atom nearly 2x the clock speed of a
900mhz Celeron running fpu-intensive apps is significantly slower?
More controversial, can we claim that Fortran is greener than other
languages because its number-crunching apps run faster?.
