C-30 was one of the first two C-Series processors, launched in
January 2011 at Consumer Electronics Show. Like other Ontario-based
parts, the C-30 features ultra-low power consumption of just 9 Watt.
The processor has one core, clocked at 1.2 GHz. Compared to Intel
Atoms, also targeting netbook market, this Fusion CPU has 35% lower
frequency, which is partially compensated by better internal
efficiency, and more powerful integrated graphics controller.
First details about C-50 appeared in November 2010, and, also in
November, the CPU was rumored to be used in upcoming Acer 10" tablet
(still not released as of end of February 2011). Information about one
of the first netbook models with this CPU, Acer Aspire One 522, was
disclosed in December 2010. The microprocessor was launched next
month, in January, at CES in Las Vegas. The AMD C-50 integrates two
CPU cores, running 200 MHz slower than the single core on the C-30,
and still manages to fit 9 Watt thermal envelope. Performance-wise,
this model is clearly better choice than the C-30 due to higher
multi-threaded performance, and improved system responsiveness.
