IGP of Pentium SNB Processor is called Intel HD Graphics
. This is identical
with Intel HD Graphics 2000 of Core i3/i5/i7 except for
the three points mentioned below. In particular, it supports
- HD audio bitstreaming
- AVC, VC-1, MPEG-2 and MVC (BR 3D codec) full hardware decode acceleration
- Almost all video post-processing tasks of Intel Clear Video Technology
(see below what are missing)
However it does not support
- HDMI 1.4a 3D video format (Frame Packing)
- Quick Sync
- A couple of Intel Clear Video Technology features: "Total Color Correction", "Skin Tone Correction", "Adaptive Contrast Enhancement".
If you don't mind these features, Pentium SNB processors, in particular G840 and G620, are highly recommended. Personally I don't see a reason to choose Core i3 over Pentium for pure 2D video playback.
As for stereoscopic 3D, it supports Side by Side, Top and Bottom, Checkerboard, and Interleaved 3D formats via CyberLink PowerDVD and ArcSoft TotalMedia Theatre. So if your 3D display does not support Frame Packing, Pentium SNB is a good choice. However 2D-3D conversion require some CPU power and perhaps you will be more comfortable with Core i3.Test Configuration and Results
Pentium G840 2.8GHz + ASRock H61M/U3S3 + DDR3-1333 2 x 2GB.
****************TrueHD/DTS-HD MA/DD+/DTS-HD HRA bistreaming
: All supported (under PowerDVD 10/11, TMT 3/5, ffdshow Audio Decoder [no DD+], LAV Audio Decoder).AVC, VC-1, MPEG-2 hardware decode acceleration
: All supported. If you don't use DXVA, the processor is still fast enough (25-45% CPU usage).1080p60 AVC Video Playback
: Just perfect. Basketball clip
with LAV Splitter + Microsoft DTV/DVD Video Decoder + EVR Custom Presenter:
- Drawn: 4941 frames
- Dropped: 2 frames (occurred only at start up)HD Deinterlacing
: Better than AMD's Motion Adaptive. The lines in the orange tubnails of the ticker are jaggy in Cheese Slices
with Microsoft DTV-DVD Video Decoder + EVR CP:
Other Intel Clear Video Technology features
: See yourself (all sliders are perfectly functional; what else should I check?):
BR 3D (MVC decode acceleration) under PowerDVD 11
: Supported (CPU usage is ~20% when HA is on, ~80% when HA is off).HDMI 1.4a 3D video format (i.e. Frame Packing)
: Not supported. All the other 3D video formats (except for 720p 120Hz alternate frame sequencing format) are supported fine.2D -> 3D conversion under PowerDVD 11
: No problem:
The performance of Pentium SNB is better than Core 2 Duo, CPU usage of E8400 3.0GHz in this task is ~80%!
How about G620 2.6GHz? Take a look at the post 2D to 3D conversion by G620
. If you are interested in this task, perhaps you will be more comfortable with G840 or higher. Personally I would choose Core i3-2100 for 2D-3D conversion.
