Die neuen Karten sind da.
Sie sind nur noch nicht lieferbar. Ende nächster Woche ist realistisch.
Wegen der Prozessoren - danke für die Aufklärung! Gibt es schon Berichte / Reviews, wie sich die neuen ATI-Chips leistungstechnisch einordnen lassen? Wichtig wäre mir zudem eine Hardwaredekodierung auf dem Niveau der alten 2600er-Serie, bei den 2400ern gab es noch Einschränkungen (laut beisammen.de oder dem AVS-Forum).
EDIT: Gerade bei ATI endeckt:
"By utilizing dedicated hardware for the decoding of VC-1 and H.264 encoded video,
the CPU is alleviated from the decoding process and the graphics pipeline and CPU
cycles are freed up. The decreased drain on system power is particularly beneficial in
notebooks, where HD playback processing on the GPU places a lesser burden on the
battery life. Less overall heat is produced, resulting in a quieter system as fans are
not required to spin as fast and move as much air to dissipate the heat.
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.
Subsequent Catalyst™ software updates have improved the situation such that VC-1
and H.264 content encoded in 1080p will play back using UVD at desktop resolutions
as high as 1920x1200 (higher than 1080p), however 1080i VC-1 and H.264/AVC as
well as HD MPEG-2 content still fall-back to fully software based decoding.
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"
Anders ausgedrückt: In Sachen Videodekodierung dürfte selbst die HD 3450 ausreichen. Fragt sich nur, wie die neuen Karten tempomäßig mit der alten Serie zu vergleichen sind, bezogen auf Gelegenheitsspieler...
