After trying out the Atom Z540 on the Vaio X, we got the faster model which was the Intel Atom Z550 running at 2.0GHz. We checked how it turned out in terms of performance.
Average temperature of the system is about 48 degrees on normal use. We also ran the system thru PC Wizard 2008 global benchmarks with the following results:
Processor Global Performance : 965
Memory Global Performance : 2,233
Video Global Performance : 69
Hard Disk Global Performance : 72
PC Wizard Rating : 334
For CPU benchmarks, these are the numbers:
Whetstone (x87 – Float.) : 2,624 MFlops
Whetstone (iSSE3 – Float.) : 4,968 MFlops
Dhrystone (iSSE3 – Int.) : 6,482 Mips
Computation of “Mandelbrot” (iSSE3) : 61.42 sec.
Windows Experience Index: 2.4

There’s a slight discrepancy between the Windows Experience Index of the Vaio X running the Atom Z550 and the Z540. Apparently, the 2.4 sub-score on the Z550 is attributed to the graphics performance — the same graphics only scored higher at 2.5 on the Z540 model.
[...] bad, considering an Atom Z550 2.0GHz has a sub-score of [...]
An impressive share, I just given this onto a colleague who was doing somewhat similar analysis on this. He in reality purchased me breakfast because I discovered it for him.. smile.
I prefer to make use of some of the content material on my blog. Naturally I’ll provide you with a hyperlink on my internet blog. Thanks for sharing.
