Intel Atom N270 vs Intel Atom N280

Intel Atom N270

► remove from comparison Intel N270

The Intel Atom N270 is a typical netbook single core CPU which is clocked at 1.6 GHz. The Atom core was designed for a low power consumption and cheap production. The downside is the relative low performance per Watt (due to the in-order execution) compared to similar clocked Celeron processors, e.g.. Still the integrated Hyper-Threading (the operating system sees the CPU as a dual core CPU) decreases the penalty of the in-order execution a bit.

The performance of the N270 is only compareable to a 1.2 GHz clocked Celeron M and therfore only sufficient for non demanding applications like Office or web surfing. HD videos, advanced photo editing, video cutting may not run fluently. 

Due to the modern 45nm process (in 2009) and the small size, the power consumption is very low (2.5 Watt TDP). Therfore, the CPU does not need a good cooling system and can be used in very small designs (like Netbooks).

Intel Atom N280

► remove from comparison Intel N280

The Intel Atom N280 is a typical netbook single core CPU which is clocked at 1.66 GHz. The Atom core was designed for a low power consumption and cheap production. The downside is the relative low performance per Watt (due to the in-order execution) compared to similar clocked Celeron processors, e.g.. Still the integrated Hyper-Threading (the operating system sees the CPU as a dual core CPU) decreases the penalty of the in-order execution a bit.

The performance of the N280 is only compareable to a 1.2-1.3 GHz clocked Celeron M and therfore only sufficient for non demanding applications like Office or web surfing. HD videos, advanced photo editing, video cutting may not run fluently. Compared to the N270, the N280 only offers a minimal higher clock speed and a faster FSB. The performance increase should not really be noticeable.

Due to the modern 45nm process (in 2009) and the small size, the power consumption is very low (2.5 Watt TDP). Therfore, the CPU does not need a good cooling system and can be used in very small designs (like Netbooks).
