The ''Efficeon'' processor was Transmeta's second-generation [[256-bit]] VLIW processor design. Like the Crusoe (a [[128-bit]] VLIW architecture), Efficeon stressed computational efficiency, low power consumption, and a low thermal footprint.

A 2004-model 1.6-GHz Transmeta Efficeon (manufactured using a [[90 nanometer|90 nm]] process) had roughly the same performance and power characteristics as a 1.6-GHz [[Intel Atom]] from 2008  (manufactured using a [[45 nanometer|45 nm]] process).<ref>{{cite web|url=http://www.tomshardware.com/reviews/intel-fires-atom-processors,1903-6.html |title=Tom's Hardware: Performance estimates: Almost a Pentium M at a fraction of the power |publisher=Tomshardware.com |date=April 1, 2008 |access-date=November 13, 2011}}</ref>{{failed verification|date=March 2014}} The Efficeon included an integrated [[Northbridge (computing)|Northbridge]], while the competing Atom required an external Northbridge chip, reducing much of the Atom's power consumption benefits.

The [[Transmeta Efficeon]] processor addressed many of Crusoe's shortcomings and showed roughly a 2x real-world improvement over Crusoe. Its die was considerably smaller than Pentium 4 and Pentium M, when compared in the same process technology. Efficeon's die fabricated in 90&nbsp;nm is 68&nbsp;mm<sup>2</sup>, which is 60% of the Pentium 4 in 90&nbsp;nm, at 112&nbsp;mm<sup>2</sup>, with both processors possessing a 1 MB L2 cache.

The notion of selling a product into a specific [[Thermal design power|thermal envelope]] was typically not understood by the mass of reviewers, who tended to compare Efficeon to the gamut of x86 microprocessors, regardless of power consumption or application.{{improper synthesis|date=March 2014}} One such example of this criticism suggests the performance still significantly lagged behind [[Banias (microprocessor)|Intel's Pentium M (Banias)]] and [[Athlon#Mobile Athlon XP|AMD's Mobile Athlon XP]].<ref>{{cite web|url=http://www.vanshardware.com/reviews/2004/04/040405_efficeon/040405_efficeon.htm |title=VHJ: Benchmarking Transmeta's efficeon |publisher=Vanshardware.com |date=April 4, 2004 |access-date=November 13, 2011}}</ref>
