Title: HTPC Build: 1 or 2?
Post by: Gatherum on February 24, 2015, 10:41:01 pm
Reposted from Nsider2, which is why obvious things, like explanations of what MC does, are present.

HTPC build 1 (http://secure.newegg.com/WishList/PublicWishDetail.aspx?WishListNumber=26161352)
HTPC build 2 (http://secure.newegg.com/WishList/PublicWishDetail.aspx?WishListNumber=19635649)
...with Panasonic UJ-265 (http://www.amazon.com/dp/B00CFXZ9VA/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=CBUF8W0GVGUB&coliid=I10EI45GHCINX8) (unavailable on Newegg)

So I am about to sell my gaming rig to a friend for about $600 (plus an additional $50 for the monitor) and replace it with a home theatre PC.

A bit of background: I originally bought and assembled the various parts for the aforementioned gaming PC back in early 2012, when I fully intended to make a concerted effort to become a PC gamer. To make a long story short, it was only after I had finished that I came to realise that many of the games I wished to play came with some sort of DRM malware (SecuROM being the most infamous). This, combined with my general distaste for WASD movement, caused me to shift my focus solely to console gaming and home theatre applications. That being said, the PC I built functions phenomenally as a high-end HTPC and has served me well these past three or so years, but for what I use it for, it is, to understate it, overkill. I have been thinking that I would like to build something a bit more modest in terms of form factor and power consumption to replace it, and the above lists represent my efforts so far.

The problem: having never seen or built an HTPC before, I am not confident that I have a clear perspective of the difference between one and a gaming PC, aside from the general knowledge that a proper build of the latter far outclasses the former (and pretty much everything else) in terms of sheer processing power and graphics rendering capabilities. Since I am building an HTPC, I am not looking to build something quite so powerful or expensive, but I am also not looking to build something underpowered as HTPC's go, and I was hoping I could get some advice from some of you on how to balance my hardware and budget to this end. :)

I appreciate any and all help and advice. :)

Pretty comprehensive write up and the only thing left is how picky you want to be about the "Video" up scaling quality.  HTPC builds can be fairly modest as most are striving for something not too loud, so devices like the JRiver Id Classic (http://jriver.com/Id/) may even fit the bill, is cheap and comes prebuilt with a Linux MC image.  This would makes a good HTPC entry level head unit.  I have the same box but running windows and it does all but BD just fine (also off external pools), my review here (http://yabb.jriver.com/interact/index.php?topic=87617.msg600098#msg600098).  

The next "step up" would be a mainstream CPU but is really all about the Video card if you want ROHQ (and the madVR high quality settings).  At which point you really want to start looking at the trade of between noise, performance and of course price.  For my main HTPC I manage to jam everything into a Shuttle SFF and the noise envolope meets my expectations just fine.

I am pleased to hear that the Id has video capability now, since I remember it being said during its development that it would not at first. :)

Still, I would like to retain ROHQ/madVR, as well as Windows, since I am still heavily reliant on DVDFab and other pieces of muxing and subtitle editing software, and because I am intrigued by the forthcoming Windows 10 in general. That in mind, would the onboard graphics/video processing in the CPU's/APU's and/or motherboards in either of those builds suffice for ROHQ? I'm actually not too worried about noise; most builds involving this chassis, high-end or not, are known to be quite satisfactorily quiet.

To use ROHQ with the best or near best settings you need a discrete video card.  To do MadVR on medium settings I can personally verify that intel's integrated graphics can do the job, I have no experience with AMD integrated graphics whatsoever.  My understanding is that they're better than Intel's in some ways, but worse in others.

To give you a calibration on what I mean, I have three systems:

Intel i5 NUC with Intel HD5000 integrated graphics: Can handle Jinc upscaling for non-interlaced material, and can handle lanczos for interlaced material, but either one requires increasing the number of buffered frames dramatically.  With normal buffering settings it can handle Lanczos for non-interlaced material, and can do lanczos with some interlaced material.

NVidia 660 Ti: Can handle Jinc upscaling for all content types, but cannot generally handle NNEDI (although I can squeak out NNEDI scaling in in some areas on some content by dramatically increasing the frame buffering).

So think about what MadVR settings you plan to use and see if you can find some benchmarks of those AMD integrated graphics models

I can't remember offhand what madVR settings I use already; I'll have to check when I get off work and post a report here. What I can say right now is that, whatever they are, they've been working perfectly fine using an NVidia GeForce GTX 560 TI.

Generally speaking, is it conceivable that an AMD APU could handle madVR at high settings? I'm really trying not to have a discreet GPU this time around.

Will I actually need at least 8 GB of RAM? Can I survive on 4 GB with an optimal setup?

Anyone?

So I played around with the madVR settings today. I have found myself to be quite satisfied with artifact removal set to high (both in general and fade in/out), chroma upscaling and image downscaling set to bicubic with a sharpness of 75, image upscaling set to Jinc at 3 taps, and smooth motion always on. For review, I have an NVidia GTX GeForce 560 TI.

1. Considering current hardware, have any of you any suggestions for changes to the above? Anything about it sound underpowering, overpowering, or just plain frivolous?
2. Are those settings reproduceable without issue on an AMD APU (either the Kabinis or the Kaveris)?

I too like Jinc3 but I really don't know how you are going to run it on the iGPU's though I've no system to test on.  From what I've seen, as better and better GPUs come out then madshi releases a better and better scaler to take advantage of the new horsepower. 

My suggestion is have a look at the picture quality of RO Std.  If you can live with that as a minimum then go ahead with your iGPU build and anything you can then squeeze out of RO HQ / madVR tweaking is a benefit.

If you can not live with RO Std then I'd be looking for a discreet GPU to make sure you have a hassle free and stable build.

For perspective, the AMD Athlon 5350 (Kabini) integrates an AMD Radeon HD 8400, whereas the A8-7660 (Kaveri) integrates something in the R7 series. These are fairly recent GPU's. I'm sure it's more complicated than that, but AMD have been known to be better about APU's than Intel is. *Shrug*
