FUD Zilla heard Intel will release a dual-core Atom N550 with 1.5GHz clockspeed in the third quarter of this year.
The distinction is obvious as N400 series will remain single-cores, while N500 series are dual-core. The dual core Atom for netbooks is clocked at 1.5GHz, it has 1MB total L2 cache, 2x512KB per core and two cores with four hyperthreads.
The TPD for this CPU is 8.5W which is two watts more than single-core 1.83GHz clocked N475. Remember, 8.5W is not that bad as this CPU has a Intel Graphics Media acceleration 3150 based core, integrated 200MHz graphics core and the big parts of northbridge.
