One difference is wattage. According to Intel’s website, the N270 draws .5 more wattage at 2.5W, where the Z530 runs at 2.0W. More power = better performance, correct?

But the clock speed and cache size remain the same. That’s strange there’s such a difference.

The problem when running benchmarks on the Sony VAIO P is it’s passive cooling (no fan for the CPU). When you put some heavy load onto the machine, e.g. running benchmarks over a longer period of time, the CPU Core temperature rises over a critical level (90° C) and the processor begins to throttle. Then it runs only with 800MHz instead of 1600Mhz.

See also page 21 of the Atom Z5xx datasheet:
http://download.intel.com/design/processor/datashts/319535.pdf

Improved Intel® Thermal Monitor mode:
-When the on-die thermal sensor indicates that the die temperature is too high, the processor can automatically perform a transition to a lower frequency and voltage specified in a software programmable MSR.
-The processor waits for a fixed time period. If the die temperature is down to acceptable levels, an up transition to the previous frequency and voltage point occurs.
-An interrupt is generated for the up and down Intel Thermal Monitor transitions enabling better system level thermal management.

I got the same problem when running benchmarks on the VAIO P (SuperPI, CrystalMark09 etc.). Sometimes the results fluctuate more than 10% or more, so i searched for the problem. I observed the CPU-Speed during benchmarks and after some time the CPU throttles to 800MHz.

If you keep this in mind, you get nearly the same results in SuperPI as Atom N270 and N280 CPU. Here are my results:

16K – 0.828s
32K – 1.719s
64K – 3.703s
128K – 8.109s
256K – 19.046s
512K – 43.609s
1M – 97.438s
2M – 224.782s

Interesting. Up to 128k, the difference isn’t much actually.

I read in NotebookReview that Dell chose Z to run its netbooks because the chipset runs A LOT cooler than N (so they claim) and hence, works even with minimal fan speed.

Apparently and moreso in netbooks, laptop heat and fan noise are primary concerns. This graph shows that the compromise wasn’t much.

Thanks!

[...] My concern is more with the heat dissipation. The core temp sits around 49 degrees centigrade on CPU idle but goes as high as 64 degrees at full CPU usage. The Vaio P doesn’t have any exhaust fan inside (Intel Atom Z5xx are generally for embedded systems that don’t require them) but there’s a small ventillation grill on the left side, where most of the heat is coming from. {Check out the difference between an Atom Z530 and the N270} [...]
