Power Specifications
The EPIA M utilizes an industry standard 20-pin ATX main connector to the power
supply. Due to the EPIA M platform’s ultra low power requirements a 90 – 120 Watt
ATX power supply is ample for even the heaviest of multimedia system applications.

DVD Payback Test
The table below compares VIA C3™ processor and CLE266 chipset DVD playback
performance to that of a powerful Intel® Pentium 4 1.7 GHz and 845 chipset with
Leadtek Geforce 4 MX440 VGA card. Despite giving away 1.167 GHz of processor
speed and competing with Geforce4 graphics the VIA CLE266 platform delivers
equivalent performance at a fraction of the cost and required space and cooling. Note
that this is a comparison of only the DVD playback performance, not a of overall
system performance, as digital media performance is what counts for the lifestyle
PC.

This table also shows that both platforms have achieved the magical figure of 30 frames per
second that indicates smooth or flawless DVD playback.
Power Consumption Tests
As the DVD playback performance is comparable in the table above, we will also look at the
different power consumption results for a range of typical home PC activities with the VIA EPIA
M-Series mainboards compared to the typical “one size fits all” platform that is being promoted by
others in the PC industry. We have also included the low power VIA EPIA-Series Mini-ITX
mainboards as a frame of reference. Where the VIA EPIA M-Series mainboards are aimed at the
living room space, the VIA EPIA 800 and fanless VIA EPIA 5000 are aimed at the thin-client,
small footprint desktop and education PC markets, although they are also being used as 1u
server, Personal Video Recorder and car PC platforms amongst others.
The “one size fits all” system that we are using as a reference platform is an Intel 845-based
Pentium 4 platform and we are comparing the power consumption to that of the VIA EPIA MSeries Mini-ITX mainboards. Some of the tests are not aimed solely at Digital Media
performance, so they also include the power consumption numbers for the VIA EPIA Mini-ITX
mainboards. All tests were conducted using the Microsoft Windows® 2000 operating system and
include the wattage consumed by the total platforms. The table below each diagram uses the
Intel platform as a frame of reference for the accompanying calculations.

DVD playback performance of these two platforms is not only flawless but the scores are also
very close to each other. In figure 2, the power consumption of the EPIA M9000 and the Fanless
EPIA ME6000 is less than half of that of the reference platform.

Power consumption of the fanless VIA EPIA ME6000 is around half of that of the reference
platform at 51.9%. It is interesting to note that for MP3 playback the fanless VIA EPIA 5000 only
uses around 1/3 of the power that the reference platform uses. This is significant power sensitive
systems like car MP3 players are gaining in popularity.

Lifestyle PC systems will be used most for digital media applications but they will also be able to
be used as fully functional PCs. The comparison above uses CC Winstone 2001 to compare
power consumption while carrying out standard office tasks like word processing, manipulating
spreadsheets and web browsing. In this comparison, the fanless VIA EPIA ME6000 mainboard
uses less than 1/3 of the power used by the reference platform. It is interesting to note that the
fanless VIA EPIA5000 uses less than 1/5 of the power used by the reference platform.

The power consumption comparison for network applications was run while
transferring large data files over a standard 10 Base T network. Here again the
power consumption of the Intel reference platform is considerably more than that of
the VIA EPIA series of Mini-ITX mainboards with the VIA EPIA5000 drawing less than
half of the power of the reference platform.

surround sound audio through a standard VIA Mainboard platform. In a nutshell,
Smart5.1 enables a mainboard’s standard three jack game/audio port to accept the
three speaker plugs that are required for 6 channel surround sound audio i.e. front
left/right, rear left/right, and center/subwoofer speakers.

Fig 1.1
Fig 1.1 above shows a VIA Mainboard with standard three jack game/audio port
configuration. The three jacks are dedicated to Line-Out, Line-In, and Mic-In usage.
The Line-Out jack is predominately used to plug in standard two channel speakers
while the Line-In jack can be used to transfer data from devices such as Mini Disks
to your PC. The Mic-In jack is used to plug in a microphone for online chatting or
conferencing. The additional onboard audio pin header is used to plug in an external
audio bracket which is the traditional method of implementing 6 channel surround
sound audio.

Smart5.1 three jack game/audio port configuration
Fig 1.2
Fig 1.2 above shows VIA’s Smart5.1 technology implemented onboard. Smart5.1
requires no additional hardware to implement 6 channel surround sound audio on a
standard VIA Mainboard platform. With Smart5.1 implemented, the left jack
becomes the Front left/right speaker port. The middle jack is for Rear left/right
speakers and the center/subwoofer speaker plugs into the right jack.
The traditional method of implementing 6 channel audio
Fig 1.3
Fig 1.3 shows the traditional method of implementing 6 channel surround sound
audio by using a combination of the left Line-Out jack for Front left/right speaker and
the bottom two jacks on the audio bracket for Rear left/right and center/subwoofer
speakers. The downside to this method is the extra cost associated with the audio
bracket and the extra complexity associated with having the three audio jacks in two
separate places. The audio bracket also places serious restrictions on the design of
entertainment devices, especially small form factor designs because the audio
bracket needs to occupy a PCI bay at the back of a chassis.

Smart5.1 - The Technology Behind The Feature
Implementing Smart5.1 on a VIA Mainboard is made possible through a combination
of hardware and software. On the hardware side, Smart5.1 circuitry has been
designed into the latest VIA Mainboards that utilize the VIA VT1616 six channel audio
codec onboard. The VIA VT1616 is a high performance six channel audio codec
designed to meet the demands of today’s PC-based multimedia entertainment
applications such as DVD audio, MP3s and computer gaming. The software that
enables Smart5.1 is embedded into the VIA audio driver so when a technician or
system integrator is setting up a VIA Mainboard he will simply choose to enable
Smart5.1 when proceeding through the driver installation and feature selection
process. To setup a set of six channel surround sound audio speaker system
becomes as seamless as plugging the three speaker plugs in the three jack
game/audio port on the back of a VIA Mainboard.
