Hi Raptor. Please include the price of OS.
Is your recommended single core system actually tested with those high bitstream 1080p files I usually mention? I only feel the hardware acceleration effect of my HD4850 and HD3870 when playing original HD DVD via PowerDVD or Nero. The 4850 couldnt even help a 3.0Ghz Pentium D machine. Original HD DVDs play well, 1080p mkv wont.
I still think the CPU is the most critical component strictly for proper playback of 1080p streams in mkv containers, and then the codec.
Sir,
Based on the expert reviews, the 780G-based motherboards paired AMD Athlon LE1640 single-core processor should be able to play smooth video without any issues, even the full HD 1080p movies. You may refer to the following links on results of the tests that were conducted -
http://www.tomshardware.com/reviews/amd-780g-chipset,1785-2.htmlhttp://www.anandtech.com/cpuchipsets/showdoc.aspx?i=3258&p=1On Tom's Hardware website review, they used an even slower single-core processor for testing Blu-ray (1080p) movies. They used a Sempron 3500+ (single-core 1.8GHz CPU), which is older architecture and slower than the Athlon LE1640 (2.7GHz). The Sempron 3500+ performed very well, with only an average CPU utilization of 63%+. They even used a lower model CPU, Sempron 3000+ (1.6GHz), and it still performed without any issues on the Blu-ray 1080p movies using PowerDVD when paired with the 780G-based motherboard. The only issue they got with the Sempron 3000+ was that the CPU was too slow for Windows Vista - almost 3 minutes daw ang boot-up.
On Anandtech website review, they used an entry level dual core processor, Ahtlon 4850e (2.5GHz). The results on playing different Blu-ray and 1080p H.264 movies were also very good. Note that the 4850e is only PhP 700 more expensive than the LE1640, so if you're planning to work on other things on the background while playing 1080p movies, this is another option. The results shows that the CPU utilization was less than 20% when playing the HD movies.
The good thing about the Anandtech review was that they showed benchmark comparison with systems using a video controller that does not have hardware acceleration for decoding HD movies - it shows that the CPU utilization shoots up 3 to 4 times compared to the video controller of the 780G-based motherboard. By the way, the integrated video controller of the 780G is a Radeon HD3200. The key is really the hardware HD decode capability.
Another analogy that I can mention are the NVidia GEForce video cards released last year. NVidia released first the high-end models, the GE Force 8800GT/GTS/GTX - these were priced at PhP 25k to 35k. These high-end models did not have hardware based HD decode capabilities, and during testing of Blu-ray movies, the CPU utilization reaches 80 to 90%. When NVidia release the mid-range levels (8600GTS), that were priced at 6k to 9k, they included the hardware HD decode - tests shows that CPU utilization dropped to 20%+ on the average when playing 1080p movies.
If the purpose of the CPU is the same as the NMT's - media player only, LE1640 is more than enough. If it is a general purpose PC, the dual-core Athlon 5000 is only PhP 1k more expensive than the LE1640 - that one or a higher model is recommended.
Regarding the price of the OS, yup you're right on this one. But if you're really tight on budget, there's always the Linux Media Center OS that's downloadable for free - all NMT's are Linux-based anyway.
