Bay Trail-D motherboards
I'm looking at the J1900 for proper 1080i deinterlacing too atm, question at fritsch why would you chose the 2955U? From what I see it is slower then the J1900 http://cpuboss.com/cpus/Intel-Celeron-J1...eron-2955U

Lol. It's nearly double that fast. It's a real haswell celeron. Not a limited baytrail.

Furthermore it has HSW graphics and not a pimped and stripped down HD4000 IVB with just 4EUs.

Edit:
Wait(!) I take that back concerning CPU performance:


J1800: http://www.passmark.com/cpubenchmark/cpu...Hz&id=2167 1177
2955U: http://www.cpubenchmark.net/cpu.php?cpu=...40+1.40GHz 1543
J1900: http://www.cpubenchmark.net/cpu.php?cpu=...Hz&id=2131 2044

So in deed - the J1900 has a correct cpu performance it is double that fast as the J1800. Though i don't like the IVB Baytrail graphics with just 4 EUs, as it's even too slow for Lanczos 3.
First decide what functions / features you expect from a system. Then decide for the hardware. Don't waste your money on crap.

Build me a Celeron 2955U in mini itx format and I will buy it :-)

Let's hope Asus hurry up and release the Chromebox in Europe. 2955U + 2GB RAM (and expandable) + 16GB M2 SSD. Only thing missing is integrated IR...

I edited my post above. But yeah, I also wait for the chromebox in europe :-)

Thanks for the info, so I guess the J1900 only gets better scores on the passmark bench because of 2 more cores but the 2955U is faster in single core performance and gpu? I am running a SU2300 celeron atm but the gen 1 ion gpu is starting to annoy me. Smile

Edit: saw your edit, thanks for taking a look. So the J1900 would need a dedicated gpu for proper 1080i deinterlacing

Yeah - I was really sad when I bought my J1800. It feels fast and so on, but the GPU performance sucks balls. Imagine you have 720p content or 576i SD content and watch that on 1080p screen. You are not able to upscale that with any "nice upscalers" just the bilinear or nearest neighbour ones and this really make a big difference when scaling.

For Yadif at 1080i50 it's not so a big problem, cause yeah bobbing also does a "good" job there.

So this still looks like a good idea then http://liliputing.com/2014/01/asus-eee-b...power.html shame it has no space for a bluray drive, but I guess I could get around that by using my main pc to rip it.

Or I just try and build my first htpc Big Grin

Nice - what's the price?

Only for 1080i50? Lanczos3 on 576i works fine here on i3-3225 with HD4000

Barebone version is around 270 euro, there is contradicting information on the fanless claim though.

I think fritsch was suggesting that the J1900 had a cut-down HD4000, not the same as on the Ivy Bridge i3s etc. So the performance could well be different?

Yes - that I said. The 3225 has 16 EUs on its HD4000, that's enough power for Lanczos 3 Optimized.

Real: HD 4000: 16 EU
HD 4000 Baytrail: 4 EU <- that sucks, even the GPU in the Celeron 847 is better.
HD 2500: 6 EU
HD 3000: 12 EU
HD 2000: 6 EU

Source: wikipedia + http://hothardware.com/Reviews/Betting-O...ed/?page=2 <- for the baytrail and yeah my personal measurments make that clear, too.

Here's a mini-ITX motherboard with an i5-4300U though it might be over your budget Big Grin

There is a 2980U version but they don't have it listed / priced.

CPUBoss isn't a source of real information . At best, it gives you the most LIMITED information humanly possible. CPUBoss is supposed to help CPU noobs better understand CPUs and which one is better. Sadly, it's many times not helpful at all and gives misinformation quite often.

Most of the things fristch is using though the average XBMC user isn't using. You'll be fine with a J1900 if you just want to watch videos. If you want to use more upscalers though then yes you'd need a better GPU.
Edit: Any good RECENT guide on upscalers? I never have boethered with it, but I have a 4770k and a HD7950. Tons of extra processing power just sitting idle. I just never noticed a difference with upscalers but I have glasses now but before I go through the trouble I'm trying to find decent comparisons. Never have been able to find what I want went googling.

Concerning upscalers: Use wikipedia

Simples ones: Bilinear, nearest neighbour
Advanced ones: Lanczos3 Optimized, Lanczos2, Spline36.

They all do what their name suggests.

I only linked the cpuboss pages, cause I did not find something else. I have a Celeron 1007U here, which is a bit slower than a 2955U, but does the Yadif job quite nicely. It's also too slow gpu wise for the Lanczos Optimized (HD2000 IVB GPU), can decode 4K - but 24p is barely working, it syncs to 24.

With that background and the tons of hardware I have here (mainly for xbmc testing and writing code), i can compare those cpuboss values quite well.

Btw. Whenever you have non 1080p content you need some GPU power for upscaling it. Lanczos3 Optimized SDTV to 1080 looks pretty good - bilinear sucks balls against it.
