The AM1 Kabini Motherboard Preview: Analyzing the Hardware
by Ian Cutress on April 19, 2014 2:00 PM ESTASRock AM1B-ITX
Moving to $40 and above brings a raft of changes – even by moving up a dollar does the AM1 landscape seem to change rapidly enough. To coin the eponymous phrase, ‘And now for something completely different’. The AM1B-ITX does what a motherboard above the base should do: add functionality and reduce complexity. Here we get double the SATA 6 Gbps ports and double the USB 3.0 ports, as well as three fan headers and an integrated parallel port on the rear panel whilst at the same time removing the need of a 4-pin CPU power connector.
ASRock has placed the 24-pin ATX connector, the four SATA 6 Gbps ports and the front panel header outside the DRAM slots (to the right), making cable management with this mini-ITX motherboard a lot easier. The SATA ports are also alternate facing to aid removal of locking SATA cables. Just inside the DRAM slots at the bottom are some of the additional headers – the COM header, the TPM header, the USB 3.0 header and two USB 2.0 headers. It might actually be a little too cramped in there.
Despite removing 4-pin CPU power connector, the top of the motherboard does look extremely busy with all the components on board. Two of the fan headers are in this area at the top left, while the third is at the bottom right. As with the other motherboards in this preview, the main PCIe 2.0 x16 slot runs at x4 mode due to the PCIe lane allocation, and of the lanes that are left ASRock has diverted one each to ASMedia controllers for the extra USB 3.0 and SATA 6 Gbps ports respectively.
While we lose the two extra USB 2.0 ports from the AM1B-M on the previous page, the rear panel gets access to more video outputs and a parallel port instead. When an antiquated port is added to a modern product, some users will bemoan its presence. More often than not, these are added because companies that use old equipment that communicates via the parallel port can cost six figures and is only updated once every few decades, so it is easier to update a $400 PC than a $400000 milling machine.

Price wise, the ASRock AM1B-ITX blows the AM1B-M out of the water. For a few extra dollars there are more ports for more of the things most users will want. There is still the issue of that bottom-of-the-barrel Realtek ALC662 though.

The whole concept of an expensive AM1 motherboard is ridiculous, because as metioned in the article, once the CPU+platform cost reaches about $80 you could buy an FM2 solution which would be significantly more powerful and have many more features.Asus, in this case, completely misses the point.

Yet it would be a dual core, with a much higher TDP. None of these Kabini boards are full ATX, either, so you're not forced into a large form factor.Admittedly, I would go FM2/FM2+ as I would want the performance, but I could make a much smaller and quieter PC with Kabini for obvious reasons.

Exactly (about the TDP). There's still reason to go AM1 over FM2(+) purely for thermal/wattage reasons. I was eyeing a super small ITX case with 60W pico PSU for HTPC use that could also serve for NAS purposes and be always on. I wouldn't run a 65-100W FM2 chip 24/7 or for HTPC use unless I wanted to do some light gaming.Ortanon - Monday, April 21, 2014 - link
This actually insinuates that a low-energy/low-heat desktop solution has a price premium the same way a high-performance desktop solution does. That kind of makes sense on the surface, but when you think about it things don't add up. A lower-TDP solution is necessarily less performant, but higher-TDP solutions aren't necessarily loud, and the differences in power draw are often negligible in terms of energy costs.All in all, a weaker system should be cheaper. Plain and simple. When I saw that it'd be at least $75 for an AM1 CPU/mobo, I just shook my head and moved along. Also they REALLY should've figured out a way to squeeze dual-channel into the spec.
My fantasy is for an AM1 board that has nothing but RAM slots and two full mini-PCIE slots. That's it. You slide a board full of cards into a tiny-ass case and boom. No stupid cables, no nothing. Hell, there's your under-$40 mobo right there. How difficult is that? I've been waiting for that for SO MANY years, and yet...

You forgot no daft ATX+12 connector rubbish.You just want a DC jack on the back plate and some switched converters on board.
And an HDMI and a USB port on the back.
But yeah, that's what I'm looking for as well.
Case + Mobo + CPU + Ram + Laptop PSU = Internet PC.

There are already SFF PSUs so that doesn't bother me as much. It just confuses me that after so many years of having mini-PCIe/mSATA, so few mini-ITX (!) motherboards have it, and far fewer than that have two (for your WiFi + SSD scenarios).Stand-alone cases could get a LOT smaller if that one change was made, not to mention the elimination of at least two cables from the build.
Really, I'd be looking to use full-speed mSATA storage on ANY size setup. The cards don't cost extra anymore.

Buy a notebook with broken screen (for next to nothing) , keep the bottom case and have your wish fullfilled ;)Flunk - Sunday, April 20, 2014 - link
If you don't produce things to hit different points of the market, how will you know they won't sell? It's worked for ASUS before.Samus - Monday, April 21, 2014 - link
Asus missed the point? ASRock is the one charging $60!ntgeralt - Saturday, April 19, 2014 - link
