AMD A8-3850 : An HTPC Perspective
by Ganesh T S on June 30, 2011 6:20 AM EST
One of the most glaring issues we found with local file playback was the chroma upsampling error. Initially, we suspected that the MPC Video Decoder (our preferred H.264 decoder for use in MPC-HC running on AMD GPUs) was at fault.
Screenshots are not allowed while playing back Blu-rays in either PowerDVD or Total Media Theater. Thankfully, playing a mounted ISO enabled screenshots while apparently retaining the same playback quality as the original Blu-ray. Since the ArcSoft video decoder is the easiest to get working with MPC-HC, we grabbed screenshots when playing back the ISO and the M2TS files using Total Media Theater. To put things on a equal footing, we took the ArcSoft decoder from Total Media Theater 5 and enabled its usage in MPC-HC. Presented below are the screenshots from approximately the same timestamp for the three cases.
| BD ISO (TMT) | BD M2TS (TMT) | Local File (MPC-HC/ArcSoft) |
Considering that the video decoder used in all the cases is the same, the difference is only in the renderer / driver applied post processing. Even assuming that the EVR CP renderer used by MPC-HC lacks the quality of the ArcSoft renderer, there is a definite difference between the local file played back from within TMT and the ISO. It can only be concluded that the AMD drivers are enabling certain post processing steps only for Blu-ray playback. Will AMD rectify this issue? Only time will tell.

I have read, off and on for the last 7 years or so articles on Anandtech, however, the ONLY reason I come here anymore is the same reason I look at CNN from time to time. For a good laugh. What started off as a fairly serious website for reviews on all things peripheral, has now turned into an INTEL propaganda machine. Seriously, when you look at all the ads, all you see is INTEL, INTEL, INTEL. Anand, if you stepped back and looked at your website as it gets pulled up, you would see what we see, a website that is no longer objective, between Intel, and Crapple you've apparently lost your objective way. I look at the obvious, AMD is the underdog, and I'll pick the underdog every time, and as far as Apple goes, it's a hell of a marketing machine, but as far as equipment goes???? The I-phone was great 4 years ago, today, it is mediocre at best, and if you're into power computing, Apple has absolutely NO compelling entry. Sadly, I resign myself to the fact that this website no longer provides me with any stimulating information, other than being an Intel/Crapple bully pulpit........

puting northbrigde inside core CPU is wonderfull in age of 32 NM but than ....that GPU radeon is still shared ram outside the processor , and NB still have to hop in out to transfer data in and out from the socket .....and it shared too with other kinda data for system stored at ram socket ddr3discreet VGA have dedicated RAM and some indenpendet core CPU too like in Nvidia , i wondering GDDR5 VS DDR3 , which one is fastes speedt?........comboing VGA is another idea but all that handle via software not at hardware it self.... so far see there is just another decoder for movies aka films format
the northbridge itself inside or outside core CPU will stressing alot hardwork to transforming coming in out data from external socket RAM....and i think it will produce more heat itself at the core
how can NB self handle 64 Gigs? i read that phenom x6 are gonna be very hot to handle 16 Gigs
intel create DMI to handle data boost at Mobos ram pci etc ...and QPI for inner core data boost...
well i not preety sure 32 Nm liano architecture are work fines in real wordl practically electron flows handling data , speed etc.....and mobo compability to manage the potential of it
pushing external DDR3 speed to act like GDDR5 for integrated VGA on same dies core ?
and i dont really care about i3 etc with VGA too i think its just another variaton for marketing thats all..seem nothing significant inovation about nano tech age can do more beyond that...
maybe doctor OCt gonna say "the power of the sun in palm of my hand "LOL
cheers
