So would this be fast enough?

Grandfather is looking for a bluray player and digital media player, currently has a TV recorder and dvd burner he'd also like to replace with an all in one unit.

Came across this.

An all in one pre-built would be ideal, but would the D525 with Ion2 be capable of TV recording while watching bluray? Or would it be a bit of a one trick pony and not really up to multitasking?

Would most likely max out the memory at 4gb and put an SSD in it, with an external drive for actual storage.

So would this be fast enough?

Recording a DTV channel or even entire stream (TS) isn't really a huge chore.  From memory it's about 20 Megabits/sec which is less than 3 Meg per second - I've found most/all of my USB flashdrives can timeshift on a PVR/STB without much trouble.

Analog TV is dead now so no point getting into that, but it actually requires more grunt to digitally record ATV since the capture is static uncompressed frames and an audio wavestream which need to be converted on the fly (in some cases there's hardware assist for that).

 

But playback is where the issues can arise with low end PC gear.  BluRay natively is MPEG-4, H.264 for originals and UHD is H.265.  Both require a reasonable amount of grunt to have smooth playback especially once the resolution goes up (generally H.265 will be in use for anything over 1920x1080)

Also, TV is starting to move to H.264 rather than the legacy MPEG-2 / H.262 standard (which has comparitively very low playback processing requirements).

 

That device - not sure.  The CPU on it's own would likely struggle but the nVidia playback assist would be of big help.  Of course whatever software you use has to actually use the hardware that's there, it's not automatic.

That CPU on the system is a really slow Atom, I had one of those on a netbook. Nope, get a faster newer system.

They're not entirely bad - I've got an old Aspire One here with an N270 which is single core/HT and is amazing in it's performance increase in benches with 2 vs 1 threads (like 50% or more better).

I've also got my Pendo 7" Windows 8 tablet which is a quad core somewhere in the 1.8 GHz range.

 

I'd have to run some benches but from memory they're in the vicinity of equivalent speed Core 2 CPUs.  Sort of sad that Intel dropped them, for portable devices the performence is OK but the power consumption vs equivalent Anrdoid devices is usually a bit poor.

Those old Atoms were replaced pretty much because their performance is the issue, the power consumption was great.

You're better off with a recent i3 than an Atom. Hyperthreading on those Atoms was pretty awful.

I've got an older single core Atom here that's actually amazing with 2 vs 1 threads.

 

Most of the multi-core Atoms in fact don't support HT.  And I suspect the single core ones likely have an advantage over mainstream single-core CPUs of the same era like maybe an extra FPU or two.
