MSI's 785GM-E65 motherboard is built around the AMD 785G and SB710 chipsets, and features 128MB integrated DDR3 SidePort memory. MSI has adapted the AMD 785G chipset into a micro-ATX form factor, an ideal size for small home and office computers, and best of all Home Theatre PCs.

High-Definition Content Playback Tests
No one can deny that high definition content has been
warmly embraced, but what with the success of Blue
Ray, today's
mainstream media center PCs need HD decoding acceleration like never before. AMD
hope to address HD decoding in the 785G chipset with its Unified Video Decoder
2. UVDs directs HD playback decoding to the integrated Radeon HD 4200 GPU,
rather than to the AMD processor, allowing the system to playback VC-1, MPEG-2
and H.264 content up to 1080p resolution with less CPU usage.
On the rear I/O of the MSI 785GM-E65 motherboard there
are HDMI, DVI-D and analog VGA connectors. The DVI and HDMI ports are HDCP
compliant, while the latter supports audio streams.
Overall, all HD playback was smooth and uninterrupted, and
showed no visible artifacting or visual anomalies. First up are the Blu-Ray
playback tests and then HDD based HD 720p/1080i content playback. The goal of
both rounds of testing is low overall CPU utilization.

Blu-Ray
High Definition content demands a lot of PC processing resources during
playback, if CPU load becomes too high that can lead to jittery video quality or
other artifacts. Many integrated graphics processors now feature Blu-Ray and
High Definition H.264, VC1 and M-PEG2 content acceleration decoders to offload
this processing from the CPU, freeing up system resources for other
tasks.
The
PCSTATS Blu-Ray HD content playback test scenario monitors average CPU
utilization. It's simple and to the point. The motherboard's integrated graphics
processor is taxed in the same way it would be in your home theatre environment,
and average percent CPU utilization monitored with Windows task manager. Lower
CPU utilization values are best, provided video playback remains smooth and
stutter free.
How PCSTATS Tests: Each integrated graphics
motherboard is connected to an ASUS MK241 wide
screen 1920x1200 (1080P) resolution LCD display with an HDMI cable. The Blu-Ray
movie "10,000 BC" (VC1 encrypted) is then played
back from Chapter 22 on an ASUS BC-1205PT
Blu-ray combo drive, using WinDVD Platinum
software and the average fluctuation of CPU load recorded. Lower results are better.

playback wasn't a huge tax on the AMD 785G chipset. While Intel's G45 chipset
paired with a Core 2 Duo E6750 stayed at around 30 to 40% CPU load,
the AMD 785G chipset stayed consistently under 30% load while playing back
high-def content. Watching Blu-ray movies over the MSI 785GM-E65's HDMI
connection was flawless, with both audio and video coming over a single cable
without any setup or playback issues.
Hard Drive 720p/1080i Video Playback
Playing high definition content on current generation PCs
can bog down even the fastest processors because there is more data to handle.
To test the integrated graphics processor's capabilities at HD content
accelerating capabilities, we played the High Definition video clip, "The
Discoverers" at 720P and 1080i from the hard drive while monitoring the
percentage of CPU utilization through Task Manager. Lower results are better.
Again,
CPU utilization on the MSI 785GM-E65 platform is minimal, high-bandwidth video
should have no problem playing on this chipset thanks to hardware accelerated
decoding.
Overclocking and benchmarks are coming up, but first a
closer look at the MSI 785GM-E64 motherboard and all it has to
offer...
