"Intel's original Z5xx processors, such as the 1.1GHz Z510 and
1.6GHz Z530, were designed to be as small as possible, offering a
14 x 13mm package and a 0.5mm ball pitch. The newly announced "P"
and "PT" parts are "larger footprint" versions, but delivered in a
22 x 22mm package using 1.0mm ball pitch, according to the
"The new parts are architecturally identical to their forebears,
with the same clock speeds, same amount of second-level cache, and
the same TDPs. But, the new Atoms include integrated heat
spreaders, making them more suitable to "thermally constrained
fanless applications," and "ideal for designs without small space
restrictions," according to Intel.
"The Atom Z530P is clocked at 1.6GHz, offering hyperthreading, a
512K second-level cache, 533MHz FSB (frontside bus), and a 2.2 Watt
TDP. Meanwhile, the Atom Z510P has the same TDP, but with a 1.1GHz
clock speed, 400MHz FSB, and no hyperthreading, according to
