Getting the Best out of an Ivy Bridge HTPC: Windows 8, madVR and More..

Network Streaming Performance - Netflix
The drivers for the Intel HD 4000 enable hardware accelerated decode and rendering for Netflix streams in Silverlight on Windows 7. The Windows 8 Netflix app has been a bit of a mystery where it is not readily evident as to whether hardware acceleration is present or not, and whether it is being really utilized. In this section, we will take a look at how Netflix behaves on Windows 7 and Windows 8. The ISP at my location is Comcast, and unfortunately, there is no access to the Netflix 5 Mbps Super HD streams yet.
Netflix on Windows 7
On Windows 7, Netflix needs the Silverlight plug-in to be installed. We played back our standard test stream using Internet Explorer.
The Silverlight plug-in attempts GPU acceleration and enables it on our system. Manual stream selection is available. The maximum playback quality has a bitrate of 64 kbps for the audio and 3 Mbps for the video.
We will take a look at the efficiency of the system while playing back the stream towards the end of this section.
Netflix on Windows 8
On Windows 8, Netflix is streamed through a Metro app. Fortunately, the same debug shortcut keys used in the Silverlight version work here too. A nice add-on touch is that the manual stream selection and playback statistics OSD can be made to appear simultaneously.
It is not immediately evident as to whether hardware acceleration is being utilized or not. However, the aspect which stands out immediately is the fact that the video playback bitrate can go as high as 3.85 Mbps. Audio still remains at a lowly 64 kbps. Hopefully, a future update to the Netflix app can provide us with the soundtracks available on specialized media streamers.
Netflix Power Consumption - Windows 7 vs Windows 8
While the Silverlight plug-in OSD helpfully reports that GPU acceleration is being taken advantage of, it doesn't indicate the efficiency in any way. On the other hand, the Windows 8 app doesn't report GPU acceleration status at all. To determine the actual efficiency of Netflix playback, we recorded power consumption at the wall for both scenarios over a 10 minute interval during the middle of the stream.
The graph presents some very interesting results. With Windows 8, the system consumes much less power and the stream is also of higher quality. GPU acceleration in the app makes the streaming more than 30% efficient when compared to the Silverlight version. Compared to Windows 7 Silverlight, the Netflix app is efficient by approximately 35%. Windows 8, by itself, seems to consume less power too. Considering these results, if Netflix forms any part of your HTPC usage scenario, it is a no-brainer to upgrade from Windows 7 to Windows 8.

Also, not everyone has a super smart TV. I have a 55" Sony series 9 (hx923). It's one of the best TVs money can buy (especially for may visual tastes), but it's smart platform sucks.I don't like to depend on a dumb machine which is what I consider TV's for things I can do 10 times better on a PC. and I've not seen a single "smart tv" platform that didn't suck monkey balls as far as usability, speed and interface design...

I can watch any kind of video i like. Even embedded videos in a web browser. Easy way is to go to the website on my phone and then hit one button and within 2 seconds its playing on the TV. I download All the TV i want to watch from torrents. with Netflix and Sky TV im pretty much coveredTouche - Tuesday, January 22, 2013 - link
First of all, it's a fully functional PC vs extremely limited TV/small media player. That right there is difference enough. Media, gaming, productivity, limitless customization...As for media capabilities, there is no match for things HTPC players, renderers, filters, codecs...provide regarding compatibility, picture quality, filtering, smoothness, per file refresh matching/switching, library organization, future proofing...

The only real difference is price. You pay serious money for stuff thats actually not relevant. Im playing blu ray quality 50gb movies with DTS HD sound in 1080p. You cant get any better than that!. Upscaling is a joke. you cant polish a turd. Its still crap quality video and its always going to look crap. You dont need a PC to work that out. Also upscaling is as good as it gets on a panasonic TV. Your PC might have good software but it wont beat the dedicated hardware built into a TV. Its a bit stupid to build a PC to watch standard Def. its like a 4k gaming PC to play diablo 2.Quite honestly my Macbook Pro would be more capable and powerful than any of your HTPC's and i can take the Mac out the house when i need to. Dedicated HTPC really is just a hobby and excuse to build a PC.

Yes, you can. Chroma upsampling, per source refresh matching, playback-refresh perfect sync... LOL on the TV hardware vs PC software.Tell the majority of the world how improving SD as much as possible is stupid.
I don't get the Macbook joke. At least I hope it's a joke.
I'll get back to PC gaming on my living room tv now. I guess Macbook and Panasonic can do that better too.

Sorry you lost all credibility when you told me that you play games with a PC on your TV.This is 2013 and Standard def has no place in my home or even my PHONE!.
You do realise that a Macbook Pro has a i7 CPU and a 650M GT GPU inside? You can also install Windows and basically you dont need a separate box to do the things you claim you need to do.
How long do you think its going to be until there is wireless display tech? then your HTPC is doomed. Because people can just use their normal PC or Laptop to do basically what you spent all that money building a dedicated device for.

Thank you captain obvious, I would never have realized that things will be somewhat different once wireless display tech gets improved.You do realize that your Macbook essentially becomes a HTPC when you hook it up to the TV? The very same thing you're dissing, though more expensive and limited.
Also, it is nice of you to selectively disregard advantages even your limited usage scenario would see, and concentrate on dissing anything not of use to you or not up to your "2013" standard (what a lousy teenage girl thing to say, btw).
I hope you can grasp the idea that many people have usage scenarios you don't, and have a great need and benefit from HTPC.

Oh, and as for the Macbook, it needs Windows to be as useful and capable as HTPC, at which point you're better of with a much cheaper laptop. And even then, as many HTPCs are doing something 24/7, or while you're away etc., it makes no sense to use a laptop. Hence the joke.Yes, yes, YOU don't need anything that doesn't come with MacOS, and YOU don't use anything HTPC related, or use it more than X hours a week, and YOU don't...so it's all just useless and nobody should have it.

First of all a HTPC is basically an underpowered limited use box sitting under your TV. This is the point. Just about every other device now does what a HTPC does without actually having to have a separate PC. A Laptop a home desktop a phone, tablet or smart TV will do 95% a dedicated HTPC will do 95% as good. They really are going to go the way of the dodo. ExtincteXces - Sunday, January 20, 2013 - link
i would definitely pick Mediaportal over XBMC or jriver
