Minimum Spec for HD/Blueray

Post by Sheaf »

Now I've ordered the bits for the main PC the g/f has said that proving I can find the money I can build a dedicated media PC for the living room 8)

Obviously, when it comes to cramming a PC into as small a case as possible, I want the lowest power, coolest running minimum spec PC I can get away with.

So, basically, what do you need as a minimum for HD/Blueray playback?

I'll be doing it on a tight budget, I just cant justify spending very much... if it comes to hundred I'd be better off just buying another xbox and using it as a media extender from the 1st PC.

It'll literally be used for playing divxs in SD and HD, iPlayer and blueray.

Case with 200W PSU is looking like £30, I'm hoping to try and get a Athlon X2 4200 from a mate who's just upgraded, so I'm thinking mobo with built in graphics and a couple of GB of RAM. I have a spare IDE HDD which wont be the best but I'd have thought for this purpose it shouldn't make any difference as it's not really read/write intensive. I assume this will be ok? I've read in various places that people are running HD on built in graphics ok, just I'm not sure what spec. Seems to me integrated is better for low power and small case if I can get away with it.

I think I read any ATI 4000 series should be fine, but what about the 3000 series? What about the nVidia options, I have no idea how they fair.

Motherboards range from £40 upwards with HDMI out, the more recent and more expensive offerings having better omboard graphics.

The mate with the Athlon 4200 measured his power usage and his system peaked at about 150W, and that's with about 6 fans, two HDDs and a big graphics card, so I'm fairly sure the 200W psu can cope btw.

Views appreciated.

I would just go for a mobo with integrated dual core Atom and onboard ION graphics.

Sounds perfect for you. Asus do one for around the £100 quid mark. HDMI and ideal for HD video apparently.

Or am I missing the point that you specifically want to use the CPU from your mate?

No, I'm not fussed about that specific cpu, just see it as a cheap option.

Just found what you're talking about - http://www.ebuyer.com/product/173797

I'm a little dubious about an atom managing HD though, I have a netbook with the VIA equivilent to the Atom, 2GB RAM and it cant touch HD. The same mate actually has an atom powered eePC and that cant touch HD either. Normal divx is no problem but HD divx or even high quality iplayer feed and it's just a stuttering frame jumping mess.

Have things changed on the atom front then?

Oh, hang on... that's a dual core atom, I missed that bit. Makes much more sense now! That has to be pretty much perfect, low power, tiny, and powerful enough, assuming the description is right. Thanks!

Just realised a couple of slight problems -

a) Only 1 x PCI slot.

b) All cards have to be half height.

I'm guessing this is a common problem if you want to make it wireless and have a TV card then. Esp the latter as TV cards dont seem to come in half height.

if you just want to play back HD, then the atonm stuff is fine, as long as you have the built in ION nvidia shizzle.

The atom is fine, even single core, for playing back HD. In 'accelerated' setups such as with nvidia GFX cards, the decoding of the mpeg stream is handled purely on the nvidia graphics chips (which has 24 cores etc).

There are reviews of the asus revo (150quid machine, single core atom with nvida atom 9400 ion built in) that can play back Full 1080p HD blueray at only 10% cpu usage from the hard disk.

there is an AS rock item called the ION pc, same chipset but dual core and bigger case, with ddr ram slots and can come with a blue ray drive, but pricier at about 250 with no optical drive.

also found a nice USB TV stick from ebuyer that is USB, although i dont know if itll work with win7 media center, and whether or not a single core atom can cope...

might buy one next month (single core acer revo) and the usb tv stick for 205quid all in, for PVR/media center...

It seems you can get wireless versions from other manufacturers too - http://www.ebuyer.com/product/165386#

Or, a socket 775 version of the same thing - http://www.novatech.co.uk/novatech/prod ... 0-D-E.html
That one has wireless AND a spare PCI-E slot for a TV card. However it's £115 without cpu/ram, so by the time it's fully kitted it'll be quite substantial I expect.

As these are all fitted with the nVidia GF9300/9400 then can I assume anything with a GF9300 or higher will cope with HD fine?

I may wait a little while and see if they bring out a wireless dual core atom version with a PCI slot, as that doesn't seem to exist atm as far as I can see. Preferably one with passive cooling or a big fan and an external PSU so it can go in a tiny case.

The Asus one is apparently very noisey btw, the fan spins at ~6000rpm!!!!

Oh, and has anyone had any experience of XBMC. Apparently that's really good? If it's good then it certainly sounds appealing as it's free....

All you need mate is a dual core processor of some kind and a video card with a Unified Video Decoder, This takes all the strain off the CPU so you get nice jitter free playback. Im sure most motherboards,graphics cards etc are HDCP compliant now so you shouldnt have to much of a problem finding a motherboard at a nice price :)

You dont even need an ION chipset to playback HD with the Atom. If you have a free MiniPCI-e slot you can add one of these:

It accelerates most popular HD formats. I have one in my Compaq mini and it handles Blu-ray disc images fine with total media theatre and MKVs in media player classic home cinema edition.

Sounds like a very handy piece of kit, i stand corrected i had never seen those untill today. TBH when i was looking at making my pc a blu ray player etc these sorts of things where not on the market as i was really into blu ray from day one in the format war. I went for a ps3 in the end and now even my laptop has blu ray :D
