VIA Nano QuadCore L4700
The VIA Nano QuadCore L4700 is a low-power 4-core processor for laptops. It is based on two VIA Nano dual core dies that are connected via the 1333MHz FSB (similar to the old Pentium D). Each core offers a 3-issue out-of-order design and is therefore faster than a similar clocked Atom core (2-issue in-order design). The L4700 has a base clock of 1.2 GHz and is able to overclock itself automatically to 1.46 GHz as long as the TDP is not fully used. To save power, the chip only offers aggressive clock gating but no power gating.
VIA published some benchmarks of the L4700 Quad-Core where it was positioned against the AMD E-350 dual-core. In all shown (multi-threaded) benchmarks, the L4700 clearly wins. However, no single thread benchmark was shown.
With 27.5 W TDP, the CPU isnt suited for very small netbooks (especially as 5W for the integrated graphics chipset have to be added).
