Intel's Haswell - An HTPC Perspective: Media Playback, 4K and QuickSync Evaluated
by Ganesh T S on June 2, 2013 8:15 PM EST4K for the Masses
After our experience with Trinity and Ivy Bridge builds for HTPC purposes, we had reached the conclusion that a discrete GPU was necessary only if advanced rendering algorithms (using madVR's resource intensive scaling algorithms) or 4K support was necessary. In fact, the 4K media player supplied by Sony along with their $25K 84" 4K TV was a Dell XPS desktop PC with a AMD graphics card's HDMI output providing the 4K signal to the TV. Ivy Bridge obtained 4K display support last October, but not over the HDMI port (which is the only way to get 4K content on supported TVs).
The good news is that Haswell's 4K over HDMI works well, in a limited sort of way. In our first experiment, we connected our build to a Sony XBR-84X900 84" 4K LED TV. The full set of supported 4K resolutions (4096x2160 @ 23 Hz and 24 Hz, as well as 3840x2160 @ 23 Hz, 24 Hz, 25 Hz, 29 Hz and 30 Hz) was driven without issues.
4K H.264 decode using DXVA2 Native and QuickSync modes in LAV Video Decoder works without issues (this works well in Ivy Bridge too, just that Ivy Bridge didn't have the ability to output 4K over HDMI or any other single video link). Using madVR with 4K is out of the question (even with DXVA2 scaling), but EVR and EVR-CP both work without dropping any frames.
Now, for the bad news: If you are hoping to drive the ~$1300 Seiki Digital SE50UY04 50" 4K TV (the cheapest 4K TV in the market right now), I would suggest some caution. Our build tried to drive a 3840x2160 @ 30 Hz resolution to the Seiki TV on boot, but the HDMI link never got locked (the display would keep flickering on and off). The frequency of locking was inversely proportional to the HDMI cable length. The NVIDIA GT 640s that we tested in the same setup with the same cables and TV managed to drive the 4K Quad FHD resolutions without problems. We were able to recreate the situation with multiple Seiki units.
At this juncture, we are not sure whether this is an issue with the ASRock Z87E-ITX board in particular or a problem for all Haswell boards. Intel suggested that the HDMI level shifter used by ASRock might not be up to the mark for 4K output, but that doesn't explain why the output to the Sony 84" TV worked without issues. In short, if you have a Seiki 4K TV and want to use a PC to drive that, we would suggest using a NVIDIA GT 640 or greater / AMD 7750 or greater for now. We will update this section as and when we reach closure on the issue with ASRock / Intel.

Plus old hardware is old and not available anymore.phoenix_rizzen - Monday, June 3, 2013 - link
Quad-core Athlon-II, CPU fan configured to spin down as needed, case fan unplugged, SSD, nVidia 210 GPU (fanless) running Linux + XBMC. Sub-$300 CDN.Why would you need an i7 for an HTPC? Why would you need a skookum dGPU? And why would you be transcoding on the HTPC? The HTPC should just play the movies on the screen that's attached to it, nothing more. The movies shouldn't reside on the HTPC, and you should be plugging in mobile devices to transfer movies to/from them. That's what the skookum "server" in the other room is for. :)

This is quite old thread, but I wanted to add, that it strikes me that my htpc usage model is totally different from the one you described. I use Atom based htpc (dualcore 2.1GHz) which is on 24x7, doing playback to HDMI 1080p tv and torrents and file serving for home network. it is up to 10w and fanless. No MadVR though.benamoo - Monday, June 3, 2013 - link
I'm wondering why no one mentioned the upcoming Ouya console and possibly many more ARM based media player boxes coming to the market next year.I've been an HTPC user for years now, but it's not worth it anymore to invest in such a costly/bulky/noisy system simply for HTPC tasks. Sure, repurposing an old system is great, actually that's what I've been doing, but building a new one from scratch (especially with a Core i7) seems to be a huge waste of money IMO.
I have high hopes for Ouya (and similar ARM/Android powered boxes). Hopefully the experience would be so good that we can finally rid ourselves of this Wintel duopoly.
Don't get me wrong. I still believe an HTPC is the best media center box out there. But these boxes can offer very similar results with a fraction of the cost.

Mainly because those ARM players has crappy GUI and limited support for file formats and containers? Try playing a Matroska file that used segment linking, has a 10-bit H.264 1080p24 video stream with at least 10Mb bitrate, a DTS-HD MA 7.1 track and also a fully-styled SSA subtitle track and you will see that Ouya console crashed and burned while doing so.sireangelus - Tuesday, June 4, 2013 - link
Can someone explain to me why they don't get themselves a laptop with some remote functionality and use that as an htpc? shouldn't it be less expensive, have a lower tdp and be more useful?HisDivineOrder - Tuesday, June 4, 2013 - link
I sincerely hope they fixed the 23.976 bug in the IGP that is included with Bay Trail. If they did, there's your HTPC of choice for anyone not obsessed with MadVR.halbhh2 - Tuesday, June 4, 2013 - link
Such a careful review makes me want to have the new A10 6700 put through the same paces.majorleague - Wednesday, June 5, 2013 - link
Here is a youtube link showing 3dmark11 and windows index rating for the 4770k 3.5ghz Haswell. Not overclocked.Youtube link:

according to the snapshots, to my eyes, the QSV quality of HD4600 is significantly better than HD4000 & x264...
