Taking full advantage of the advanced VIA CoolStream™ architecture and world-class 90nm manufacturing, the new 1GHz VIA Eden ULV processor has an incredibly low maximum design power (TDP) of just 3.5 watts and the 1.5GHz part of just 7.5 watts, while the whole VIA Eden processor family boasts the industry’s lowest idle power of just half a watt. The new VIA Eden processor line is shipping now.
VIA Technologies, Inc, a leading innovator and developer of silicon chip
technologies and PC platform solutions, today announced the new fanless VIA
Eden™ processor family with the VIA V4 bus, including the ultra low voltage VIA
Eden ULV processors that offer unbeatable power efficiency in design and
performance within the compact nanoBGA2 package of 21mm x 21mm .
Taking full advantage of the advanced VIA CoolStream™ architecture and
world-class 90nm manufacturing, the new 1GHz VIA Eden ULV processor has an
incredibly low maximum design power (TDP) of just 3.5 watts and the 1.5GHz part
of just 7.5 watts, while the whole VIA Eden processor family boasts the
industry’s lowest idle power of just half a watt.
The highly efficient VIA V4 bus interface of the new VIA C7™ processor family
enables VIA Eden processors to deliver unprecedented performance in the embedded
field, with an average performance increase of more than 30% across leading
industry benchmarks over previous VIA Eden processor generations, while
maintaining the signature fanless operation through enhanced power efficiency to
ensure no active cooling is required.
"To be able to offer processor speeds up to 1.5GHz within such a low power
envelope is a remarkable advance for the x86 market, placing us clearly ahead of
the competition and enabling more powerful embedded and silent systems," said
Richard Brown, Vice President of Corporate Marketing, VIA Technologies, Inc.
"With these unprecedented levels of performance and power efficiency, the new
VIA Eden processor looks set to extend our leadership in markets such as thin
clients, where increasingly intelligent, stylish x86 devices require more
powerful yet still very cool processing capabilities."
Specifically targeted at a range of business, industrial and commercial
applications such as thin clients, silent desktops, IPCs and set top boxes, the
new VIA Eden processor line is available at different speeds to meet the needs
of those different vertical market segments. All of the new processors have been
designed to operate at very low maximum power (TDP); ranging from 400MHz at just
2.5W up to 1.2GHz at 7W. The ultra low voltage skus, VIA Eden ULV processors,
take power-efficiency a quantum step further, with the 1GHz and 1.5GHz parts
designed for a maximum of an incredibly low 3.5W and 7.5W respectively.
Operating power is further reduced with VIA PowerSaver™ technology that enables
the VIA Eden processor to transition between maximum processor speed and the
lowest speed of 400MHz, depending on application requirements, within a single
clock cycle, which also ensures seamless running of real-time operating systems
and ensures no latency issues.
The new VIA Eden processor boasts competitive write bandwidth and linear
ordering modes, as well as MMX, SSE2 and SSE3 support for enhanced multimedia
performance, and 128KB of both L1 and L2 on-die cache. It also integrates the
world’s most comprehensive set of security tools in the VIA PadLock™ Security
Engine, which can be enabled within applications to provide military-grade
protection of business or personal information.

About the VIA Eden Processor
The VIA Eden processor is based on the advanced VIA CoolStream™ architecture
of the ‘Esther’ core that minimizes power consumption within an ultra compact
die while optimizing performance, making it an ideal solution for a wide range
of business, industrial and commercial systems. Consuming as little as 500mW
(0.5W) idle power and a maximum thermal design power (TDP) of no more than 7.5
watts at 1.5GHz, the VIA Eden processor also features VIA PowerSaver technology
to reduce processor power draw. With its low profile nanoBGA2 package measuring
just 21mm x 21mm, the VIA Eden processor has no active cooling requirements to
enable slimmer, enclosed or silent designs.
Fully compatible with all leading operating systems, the VIA Eden processor
family is available at speeds from 400MHz to 1.5GHz and boasts a host of
performance features within the VIA StepAhead™ Technology Suite, including
sixteen pipeline stages, support for SSE2 and the advanced SSE3 multimedia 3D
instruction sets, a full-speed Floating Point Unit (FPU) and an
efficiency-enhanced 128KB full-speed exclusive L2 cache with 32-way
associativity for memory optimization. Coupled with the VIA CN700 digital media
IGP chipset, the VIA Eden processor provides smooth playback of digital video
and audio, and offers exceptional memory and peripheral support. The unique
TwinTurbo™ dual-PLL implementation with VIA PowerSaver technology acts like an
automatic transmission, permitting smooth transition between the maximum and
minimum power states within one clock cycle, ensuring always-on service and
The VIA PadLock Security Engine integrated within the VIA Eden processor,
provides on-die hardware acceleration for key cryptographic operations and
ensures speeds and efficiency many times that available in software, yet with
negligible impact on processor performance. In addition to the quantum-based
random number generator (RNG) and AES Encryption Engine provided in the previous
processor generation, the VIA Eden processor adds SHA-1 and SHA-256 hashing for
secure message digests, and a hardware based Montgomery Multiplier supporting
key sizes up to 32K in length to accelerate public key cryptography, such as RSA™.
The VIA Eden processor also provides execute protection (NX), preventing the
proliferation of malicious software such as worms and viruses, and is used in
Microsoft® Windows® XP with SP2.
