USB Speed
For this benchmark, we run CrystalDiskMark to determine the ideal sequential read and write speeds for the USB port using our 64GB Patriot SuperSpeed USB 3.0 drive. Then we transfer a set size of files from the SSD to the USB drive, and monitor the time taken to transfer. The files transferred are a 1.52 GB set of 2867 files across 320 folders – 95% of these files are small typical website files, and the rest (90% of the size) are the videos used in the Sorenson Squeeze test.
USB 2.0 performance is in the top half of our A75 testing.
USB 3.0 is also good, but all the ASUS boards using default USB 3.0 drivers are some 7+ seconds behind the Gigabyte A75-UD4H.
SATA Testing
We also use CrystalDiskMark for SATA port testing. The operating system is installed on the SSD, and the sequential test is run at the 5 x 1000 MB level. This test probes the efficiency of the data delivery system between the chipset and the drive, or in the case of additional SATA ports provided by a third party controller, the efficiency between the controller, the chipset and the drive.
Unfortunately, there seems to be some limitation with ASUS boards in write speeds of SATA 6 Gbps compared to our other non-ASUS board tested.
DPC Latency
Deferred Procedure Call latency is a way in which Windows handles interrupt servicing. In order to wait for a processor to acknowledge the request, the system will queue all interrupt requests by priority. Critical interrupts will be handled as soon as possible, whereas lesser priority requests, such as audio, will be further down the line. So if the audio device requires data, it will have to wait until the request is processed before the buffer is filled. If the device drivers of higher priority components in a system are poorly implemented, this can cause delays in request scheduling and process time, resulting in an empty audio buffer – this leads to characteristic audible pauses, pops and clicks. Having a bigger buffer and correctly implemented system drivers obviously helps in this regard. The DPC latency checker measures how much time is processing DPCs from driver invocation – the lower the value will result in better audio transfer at smaller buffer sizes. Results are measured in microseconds and taken as the peak latency while cycling through a series of short HD videos - under 500 microseconds usually gets the green light, but the lower the better.
DPC Latency (once AI Suite II is turned off) is very amenable compared to other A75 boards.

Have not tested 3870K but tried the 3670K and was easily able to hit to 3.8GHz no APU bus adjustment just multipler. I tested this on -M, -V Pro, -V EVO and -I Deluxe. Make sure though you updated to the latest UEFI to correctly and fully support the K series APUs.ET - Sunday, January 22, 2012 - link
That "Level Up!!" text on the TurboV EVO screen made me think that it would be cool if playing with the BIOS could be made into a game. Give achievements for exploring the BIOS, up the user's hardware hacker level when he changes stuff successfully without making the PC unbootable.Basilisk - Sunday, January 22, 2012 - link
(Here's my chance to look dim.)Looking at the comparison table on the first page, I thought "Oh crud... they dropped eSata on the uATX board." eSata's my fetish, I suppose. Then I read the "Board Features" on "Inside the Box" and did a double-take when it listed "1 x eSATA 6 Gbps", so my hopes rose... until I looked a the pix of the back-panel and the box contents [for brackets].
Alas, I suspect you've a (minor) error and the eSata's missing. Even sadder that it's missing on the ITX board, as external resources and backups become even more valuable (to me) there.

The ITX board has eSata on the I/O shield, just look at the review pics at the bottom of this page:http://www.anandtech.com/show/4833/asus-f1a75i-del... (It's between the clear CMOS and DVI and below the 2 red USB ports.)
This mATX board doesn't have eSata on the I/O shield and doesn't provide a PCI bracket, but you can always purchase one of those for $2. :-)

The mini-itx is expensive in part because of the wireless keyboard and wifi.It's worthless for overclocking mostly due to the lack of a higher bclk divider.
To be honest if I wanted a matx fm1 motherboard I'd go with gigabyte's solution.

our - I Deluxe has been tested to reach the same performance numbers ( APU bus scaling and multipler scaling for K series as the rest of our F1A boards ( -V Pro or -M Pro ). latest UEFI is recommended if you want to have highest potential under both AHCI and IDE ranges.bobbyto34 - Monday, January 23, 2012 - link
thanks a lot for the dpc latency test ! It's very useful for musicians when you want to buy a rig for audio recording !DaneelSE - Monday, January 23, 2012 - link
One promising use for a u-ATX board is using it as a base for a HTPC build. Somehow there seem to be a lack of interest in this arena from reviewers.It would be very interesting to see a real life use scenario benchmarked with power usage. How low can we push a platform in power usage wjhile still performing a few mundane tasks simultaneously.
Just brainstorming here to give an example of possible tasks that would be run at the same time.
1. Watching a DVB-T HD-channel
2. Recording a second channel on a different MUX
3. Transcoding a third recording on low priority
4. Have a internet browser in the background with some predefined work load.
It would be very interesting to see this as a usage case where the reviewer tries to push the power usage down while conserving the end user experience.
I think it would be interesting to see how AMD probably beats Intel until Ivybridge get released and then possibly see a throne shift back and forth a few times.

Sadly just about the only sensible use for Llano is in an HTPC build. (or as low powered laptop which it is very good at).Problem for me is that our cable operator (Virgin) has a TiVo box which lets me watch one channel and record 2 at same time so any HTPC build I do only really needs a mini-itx board (and complete silence!). Hoping that the reviews of Zotac's announcements at CES will take away need for building my own.
Anyway back to a proper HTPC build. The main issues are:
1. Noise. Fans not allowed (except at very low RPM). I want to hear the TV not the HTPC - this is a big problem for me with my Blu-ray player.
2. Sound. There is a big debate as to whether sound is better going through HDMI port or not. Personally I prefer fewer cables to more and my ears are not good enough to tell the difference so sound has tobe routed through HDMI
3. Picture quality: Obviously vital for an HTPC and a big plus for AMD, happy to use integrated graphics here provided (Intel note) frame rate is perfect. Using Integrated graphics frees up a PCI/PCI-E slot for something else.
4. TV card or cards: Dual channel is minimum acceptable.
So for me I can probably built a nice HTPC using mini-itx but if you want to use the full potential of a Micro-Atx you could build one say with 2xdual channel TV cards, separate sound card and GPU - cooling and noise would be an issue though

I fully understand the limitations and possibilities, and probably am able to work this out by myself.My comment was aimed at how a u-atx review is done. There are a few different target readers.
1. Gamers that want their box as small as possible (Did I hear Zotac Z68-ITX WiFi)
2. HTPC builders that want a all in one solution
3. Small desktop builds where the extra PCIe slots are vital
4. Small server/storage builds
I understand that every review can't cover all bases, but surely a HTPC oriented series of reviews would get a lot of clicks and readers.
Regarding your itemized list
1. good comment and I somehow think consumed power relates to cooling needed. Fan and noise belongs in Case-reviews.
2. Separate review, however the onboard quality should be measured, if nothing else using RMAA
3. I know that Anandtech has reviewers specialized in this area and it should of course be included if IGP is present, if nothing else to indicate when discrete is needed to reach acceptable levels.
4. Agree, wouldn't make sense otherwise, and still debatable if you really need to go as high as u-ATX.
