E350 Overclocking - Page 2

post #11 of 13
Thread Starter 
On an Athlon II X2 at 2.7GHz, it was around 40% usage but peaked up to 80%. Does it matter at 720p or not?

Interesting, most of the load was only on single core.


When is Silverlight 5 due?

40% on Athlon II X2 2.7 GHz? No wonder both Atom and Zacate can't cope. Just double-checked on my laptop (very slightly oc'ed from 1.30 -> 1.36 GHz). Based on the A/V stats, CPU usage was around 40~70% process and 60~90% system. I experienced a few frame drops and in those parts, CPU usage was at 40% process and 100% system. I didn't really have anything running in the background so I can only assume Netflix's Silverlight player requires quite a bit of CPU overhead. From Resource Monitor, load appears to be fairly evenly balanced between the two cores of the SU7300.

On my Celeron E3300 2.5 GHz, CPU usage was 15~40% process and 25~65% system. No frame drops. Wasn't able to monitor load distribution on this one. This build even had Microsoft Security Essentials running in the background. None of my Atom and Zacate systems (bar my brother's netbook) have anti-virus software installed. They tend to slow to a crawl with AV running in the background.

The 2350Kbps and 3600Kbps streams are both 720p HD. You'll notice there's an "HD" identifier in the player taskbar. It's normally grayed-out when you're viewing the SD streams and gets lit up when streaming at 2350 or 3600 Kbps.

On closed systems (PS3, TiVo, Blu-ray players, etc), Netflix even has some videos available on 1080p HD. No idea what bitrate they're using for those.

No idea when official release is. I guess that depends on how many bugs they have in the beta. I think target date is summer, though.

Hmm, Silverlight 5 might not actually do anything for Netflix. It adds H.264 decode acceleration but apparently, it's possible that Netflix is using VC-1.
