As part of our test setup, we are slowly migrating to newer drivers for our discrete GPU tests, as well as updating the tests appropriately. However, as it is only fair to test like for like, comparisons will only be made with results achieved with the same drivers.
Comparison to Other Reviews
Where applicable, the results in this review are directly compared to the following chipsets and boards which we have reviewed previously:
Note: The main comparison point for the ASUS F1A75-I Deluxe for us is the ASRock A75 Extreme6 we have already tested. As a result of that review, which was run with DDR3-1333 settings to compare to Sandy Bridge boards, I have been asked to run future Llano reviews at DDR3-1866, which Llano supports natively. For logistical reasons, there is also a CPU discrepancy, where today we are using an A6-3650 (2.6 GHz, 320 SP IGP), and in the A75 Extreme6, an A8-3850 (2.9 GHz, 400 SP IGP) was used. In analysing the results, these factors will be taken into account.
Power Consumption
Power consumption was tested on the system as a whole with a wall meter connected to the power supply, while in a dual GPU configuration. This method allows us to compare the power management of the UEFI and the board to supply components with power under load, and includes typical PSU losses due to efficiency. These are the real world values that consumers may expect from a typical system (minus the monitor) using this motherboard.
The only board to compare the F1A75-I Deluxe to is the A75 Extreme6 board I reviewed a few months ago. Both boards perform similarly.
CPU Temperatures
With most users running their boards on purely default BIOS settings, we are running at default settings for the CPU temperature tests. This is, in our outward view, an indication of how well (or how adventurous) the vendor has their BIOS configured on automatic settings. With a certain number of vendors not making CPU voltage, turbo voltage or LLC options configurable to the end user, which would directly affect power consumption and CPU temperatures at various usage levels, we find the test appropriate for the majority of cases. This does conflict somewhat with some vendors' methodology of providing a list of 'suggested' settings for reviewers to use. But unless those settings being implemented automatically for the end user, all these settings do for us it attempt to skew the results, and thus provide an unbalanced 'out of the box' result list to the readers who will rely on those default settings to make a judgment.
Compared to the board we have tested, the F1A75 Deluxe does well on CPU temperatures, even compared to the low powered Fusion boards with passive cooling, and the Sandy Bridge boards.

Well, see, here's where you're wrong and that's why it would have been nice to test that.This hardware was using 122 watts WITH an additional video card, on a 1000 watts power supply that has 80.8% efficiency at such low loads.
So realistically, the system uses about 110 real watts on full load WITH the additional video card.
I would have liked to know how much is the system actually using WITHOUT an extra video card - my guess is the consumption would drop by about 30 watts in load and about 10-15 watts in idle.
An 120 watt pico PSU has about 87% efficiency and can only deliver about 6-8 Amps on 12v line, when powered from a 19v laptop adapter (it's irrelevant how efficient this adapter is for this talk).
So assuming the pico psu can do a maximum of 6A on 12v (72w), it really makes a difference if the consumption drops to about 85-90 watts in total without an additional video card (because memory/ uses the 3.3v lines and 5v is used by the USB port/lan/wireless and the SSD, so the rest would probably fit in those 6 Amps of 12v power)
As for the ripple paragraph, both the laptop adapter AND the pico psu power converter do filtering so they're quite good and provite quality power to the system, see : jonnyguru.com/modules.php?name=NDReviews&op=Story5&reid=207
As things are now, as the tests were made with 1000w psu and only with an extra video card (would you like future systems to only be tested in Crossfire or SLI?) ... there's really no way to form an opinion.
And as for the middle paragraph...I own a Seasonic X-650, which according to tests can manage up to 92.5% efficiency. The results would have been much closer to the reality and the tests could still be done on other systems even with two power hungry video cards

Oh... and a last thing...The system was tested with the Corsair water cooler - the pump itself uses 2-3 watts of power and you also need a fan to cool the radiator, which is at least another 2 watts...
The stock cooler for the processor probably uses less than 3 watts at full speed.
I know, it's very little but it adds up, and the majority of the people buying these things won't buy water coolers for them and 1000w power supplies.

The whole review is subpar. Aside from the language I'm sure all of 3 people reading cared for water cooling comments or the above mentioned power consumption figures off a 1000w PSU. There's no word about wifi. Not what it is or whether it even works at all. For the future, guys, please, boot up from an Ubuntu live CD, type 'sudo iw list', 'sudo lshw -C network -sanitize', and 'sudo lspci -v' and save outputs as an attachment to the article. Trust me it'll be far better help to at least half the people reading the articles and actually thinking of buying this stuff.And you do have to get on their butts about not providing a vertical mini PCIe slot, it costs them more to do it because they have to make a bracket since mini PCIe cards won't stay up by themselves; in the low profile fitting you'll be limited to half size cards only replacements. And you'll want to replace it if what Zotac puts in their boards is any indication - and not that I'm knocking them for it, I'd much rather have mini PCIe with a vertical bracket than anything in the slot anyway.
No word on bluetooth either.

However, I think the AsRock A75M-ITX can be more appealing, because of it's different CPU socket position. I have that board because it will fit a Scythe Big Shuriken (awesome low-ish profile cooler) and still have the PCIe slot uncovered (not using it at the moment but it's nice to know I can). Designs such as the Asus here have the problem of having the CPU socket too close to the slot. If you want to use the PCIe slot you either need quite a small cooler (read: loud) or go with a water cooling all-in-one and that brings a whole other pack of problems.Still, it's great to see ITX boards being offered for new systems! The more the better!

Considering the features on these baby boards.. I don't quite understand why they command a premium. One would think they'd come in at a lower price point then some of the value MATX boards.DanNeely - Saturday, October 1, 2011 - link
They're more expensive because packing everything in so tightly requires using more compact controller chips for 3rd party features instead of the larger, cheaper versions on full size boards and because squeezing everything together so tightly means having to use more layers in the PCB to connect everything. Packing everything together so tightly makes avoiding EMI problems between components more difficult as well.On top of the engineering challenges miniITX boards are sufficently low volume parts that you start paying penalties in manufacturing costs and have to fund more engineering time per board.
just4U - Saturday, October 1, 2011 - link
I didn't realize the boards had more layers.. when I see these reviews I think of barebone boards like ones made for OEMs and such. Makes some sense I suppose.. Still I think all in all I'd be more likely to pick up a feature rich MATX in the same price range over something like this.. Yeah your casing might be marginally bigger but even so.Death666Angel - Saturday, October 1, 2011 - link
I have a mini ITX case with these measurements:185x240x70 mm
I have barely any space left and right (mini ITX is 170x170mm) and the space that I have in front is used for the built-in PSU dc/dc converter. This case has 3.1l volume. If I were to have the exact same case, just with a mATX mainboard (adding 74mm to the width and depth), I would get:
259x314x70mm, resulting in 5.7l volume, almost doubling it.
That's not something I'd refer to as "marginally bigger".
You really can't compare (m)ATX to ITX in my opinion. :-)

The difference between mini ITX cases and micro ATX cases is substantial. It doesn't take much effort to chop the two inches off of an ATX board to make it micro. Making a micro into a mini is entirely different. Mini ITX boards are 6.7 in x 6.7 in, and most of that gets taken up by the CPU socket/VRM area as well as the DIMM slots. Add in the PCIE slot and you don't have much to work with.Most uATX cases are still 17" deep and 8" wide by at least 13" tall. Many mini ITX enclosures are closer to the size of a Nintendo Wii. Most people don't need such a small system, but if you do it's usually worth the premium. BIOS/UEFI options on a small board are worth their weight in gold, as are competent WiFi options. Under volting is a must have for AMD systems, but 1155 Intel CPUs don't have much to gain from it. With a feature-laden ITX board, a powerful but low tdp processor, and some solid state storage, there's not really many compromises to make. With the right case and mobo you can toss in a powerful GPU, further expanding its range of uses. Or toss in an InfiniTV Quad tuner card and record 4 hd cable streams simultaneously. That's why these boards are great -- there's not much of a limit to the possibilities.

First off, the numbers are in favor of ATX and mATX boards, since they just sell more volume. Then, you generally don't have extra stuff like WLAN on most of those standard boards. The layout for the bigger boards is significantly less crowded resulting in easier manufacturing as well.You cannot look at ITX and think "hm, they took an ATX board and just cut stuff off". You have to think "hm, they took an ATX board and just condensed it into this mini board". Offering the same things on less space is generally more expensive. This applies here. The few (RAM, PCI, PCIe) slots you lose unfortunately aren't big money savers ;).
