Ako se dobro sjećam 2400 serija zbog 64 bita sabirnice nije imala dovoljan bandwidth za sve HD modove...za 3400 nisam nigdje na netu vidio da se ljudi žale, doduše
Edit:
"Processing of HD video requires large amounts of memory bandwidth. The initial
implementation of UVD on the ATI RadeonTM HD 2000 series had restrictions
dependant on the available memory bandwidth on a given board. The net result was,
at launch, the lowest bandwidth ATI RadeonTM HD 2400 PRO solutions targeted
playback of all HD content at 720p pixel resolutions. If the desktop resolution was
set any higher than 720p, then HD video decoding would fall-back to software in
order to save GPU bandwidth.
The ATI RadeonTM HD 3000 series of graphics processors features improvements to
the UVD engine that both reduce CPU utilization under HD decode and also improve
memory bandwidth utilization in order to maintain hardware HD decoding at higher
resolutions. The net result is that even the DDR2 equipped ATI Radeon™ HD 3450
will facilitate hardware decoding of 1080p and 1080i VC-1 and H.264/AVC encoded
content at 1920x1200 / 1080p desktop resolutions. "
