The build process and thermal performance of a fanless Ivy Bridge HTPC was covered in detail last month. I had indicated that the piece would be the first of a three-part HTPC series. Today, we are looking at the second part of the series. My original intention was to present the HTPC oriented benchmarks and aspects of the PC as it was built in the first part.

After a few experiments, we had to do some updates to the build in terms of both hardware and software (OS). The first hint of trouble came when I was unable to reproduce the performance of the i7-3770K Ivy Bridge HTPC with respect to madVR despite having DRAM running at 1600 MHz instead of 1333 MHz. The second was more of a decision to test out what Windows 8 offers to HTPC users. As you will see in later sections, Windows 8 offers a host of advantages to the HTPC user while also presenting some roadblocks. 

In our initial build, we had avoided filling up the second DRAM slot because the DRAM heat sink ended up scraping against the capacitors in the Nano150 PSU. Unfortunately, this meant that we had halved the memory bandwidth available to the processor. madVR, in particular, is very sensitive to bandwidth constraints. We fixed this by deciding to allow the heat sink to touch the capacitors and ended up increasing the installed memory from 4 GB to 8 GB. In order to install Windows 8, we added another SSD to the system and set the unit up in a dual boot configuration with both Windows 7 and Windows 8. We were able to perform sensible power consumption comparisons between the two operating systems in this scenario (same hardware and software configuration except for the OS itself).

In the rest of the piece, we will be looking at the general performance metrics, network streaming performance (Netflix and YouTube), refresh rate handling, HTPC decoding and rendering benchmarks for various combinations of decoders and renderers and revisit the power consumption and thermal profile of the system. Before proceeding further, the table below summarizes the hardware and software configuration of the unit under consideration.

    In every test I still wonder about how Linux/Ubuntu (insert random distro) will preform these would a linux setup do it's job? :)

    It's usually pretty good with the proprietary NVIDIA drivers. Other platforms, not so much, you're generally better off with Windows in terms of performance.

    Pretty good with the Intel Mesa drivers too, VA-API is quite well supported now, especially in XBMC.

    Home Theatre PC? LOL

    My Panasonic GT50 will play MKV ripped full 45gb Blu rays right off a HDD without problem

    i have netflix and a ton of other video stuff right on the TV.

    I fail to see why you would spend any money on a HTPC any more.

    Your Plasma TV has built in CableCard tuners and terabytes of storage for DVR duty? CableCard leases are usually ~$2 a month vs. ~$10-20 a month for DVRs from your cable company. It's easy to have 8+ HD tuners with basically limitless storage with WMC. HTPCs can be a lot more than glorified media streamers, and your TV doesn't come anywhere close to fulfilling all of the use cases a HTPC can.

    For a start the UK doesnt suffer your cable company issues. We have 2 providers that are not that expensive and include DVR for FREE. Plus you can connect a 2TB HDD to the TV and play Blu ray rips and record like a DVR on the same drive. God knows why you would want to store all those TV shows anyway they are pretty much on every torrent website anyway. Quite frankly a HTPC in this era just isnt worth the money. No matter how you spin it

    Problems start cropping up when the decoder in your GT50 refuses to play the MKV off the torrent site.

    I bet your GT50 doesn't do HD audio bitstreaming, and I am pretty sure the online experience (quick check up of something on the browser or automatic metadata downloading) doesn't work out to be the same as that of a HTPC.

    Even without using tuners, I would recommend going the HTPC route if you can afford it.

    I just recently ran into the problem where my Samsung TV would play some, but not all MKVs I've downloaded. Plus, the interface for playing video files on a NAS is terrible on all devices. Pretty much any app is better. UI, metadata, and remembering how much of a video you played is just as important as being able to watch a video.

    DVRs usually aren't really "free", they just increase the package price to compensate. My HTPC has already paid for itself and is now saving me money every single month. That isn't "spin", it's just a fact. And your entire post is ludicrous considering you are pointing out geographical differences and that your situation doesn't match everyone else's, then turn around and say nobody has a reason to have a HTPC. Your provider gives as many DVRs as you want for free? Here some providers include one "for free" but the package is really another ~$20 a month vs. leasing a CableCard. And every 2nd/3rd/4th DVR or STB you need is more money out the window every single month. It cracks me up how myopic people like you can be and how you think your single use case applies to everyone on the planet.

    Our 1TB DVR is free and quite honestly not that much of a big deal. There must be some weird American obsession with recording tv shows that the rest of the world doesn't share. To build a pc for the sole purpose is pretty extreme.

    Also I have yet to have an mkv that won't play on the Panasonic tv. I was surprised myself but really this review just shows how a htpc is just an excuse to build a pc
