990FX Motherboard Roundup with Thuban and Bulldozer – A Second Wind for ASUS, Gigabyte, MSI and Biostar
by Ian Cutress on April 5, 2012 11:00 AM ESTUSB 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.
A lot of how the system deals with USB interactions is based on the hardware, including BIOS stated priorities, but also on the software and drivers supplied. This results in our spread on USB 2.0 and USB 3.0 speeds/times. On the whole the Sabertooth 990FX is a good performer, while the MSI tends to lag behind in real world testing.
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.
For SATA testing, again we get a processor independent spread. The interesting thing here is the SATA 6 Write results, in which the ASUS boards clearly have an advantage over the other products. This is most likely due to more agressive BIOS settings at default.
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 - less than 500 microseconds usually gets the green light, but the lower the better.
DPC Latency always shows the biggest differences between our motherboards. It is hampered by the fact that it can be disturbed by software. In particular, ASUS' AI Suite and Gigabyte's EasyTune software, when installed, initialise themselves on startup and continuously monitor the motherboard sensors (by pinging them every 3-5 seconds). This request for data has a higher priority, and thus when we do our DPC checks, those boards when the software is enabled shoot up to 3000 microseconds or more. For these tests, we disable the software (as it shows uncharacteristic spikes) to take a reading while playing HD video. In this case, we can confirm that ASUS do it best, and you get what you pay for with respect to the Biostar motherboard.

"The third generation FX processor, codename Steamroller, is still reported (not confirmed) to use AM3+, meaning that there are still quite a few years left in this platform when taking the AMD route."If this is true then i simply cannot believe that AMD will continue on socket AM3+ without a chipset that supports PCIe 3.0!
Where, when, and what will the 1090FX chipset arrive?

This seems to be an ok roundup of AMD boards.However, how do the latest Windows 7 tweaks increase the performance of the Bulldozer? Can we get a before and after benchmark based on Win 7 and or Win 8 (beta) optimizations?
I was hoping we would get that information. Also, how does it compare to similarly priced Intel offerings?

Thank you for your comment. I didn't perform comparisons as Anand did a comprehensive look at the scheduling updates here:http://www.anandtech.com/show/5448/the-bulldozer-s...
(Also reviewing five boards and writing 20,000 words about them takes longer than you think!)
If there are any motherboards you would like to see in the future (or particular tests), drop me an email (ian AT anandtech.com) and I will have a look. Obviously I can't take care of every little niche test that everyone wants, otherwise we'd only get one board a month out for review, but I'll do what I can!

Thank you for the link. That is what I wanted.StevoLincolnite - Thursday, April 5, 2012 - link
I noticed your Thuban was hitting 60'C+So I was just wondering if you took the Thubans thermal bug into account on those readings? On my old 1090T and 1045T I had to have a 13'c offset to get a correct thermal reading.

Temperature related problem have long been rectified in C3 stepping of Denab CPUs and in Thuban as well. There is no fault in temperature sensor anymore in our CPUs.Only C2 rev. or earlier rev. AMD CPUs suffered from this issue.

More to life than gaming on your PC. If you read the article, you could see how terrible the non-gaming benchmarks are for 'only' a Intel 4 and 6-core vs the 8-core AMD. Fanboi much?blazeoptimus - Thursday, April 5, 2012 - link
I bought an MSI 990FX-GD80 board a couple of months ago and was looking for a review like this one at the time. I would have loved the info you brought up here and I hope it will help others looking into the available 990FX boards.I went with the MSI board since it seemed to hit a sweet spot on features, price (newegg was offering $20 off which put it to $169) and performance. I also went with a Zosma processor since it seemed to hit the price elbow and had the most unlocking potential. I've been very happy with the experience thus far. I've been able to unlock the 2 additional processors and have pushed the clock to 3600mhz (stock is 3k). My next push will be to see if I can hit the aggressive clocks listed in this article.
Thanks again for the write up. I'm a long time reader and frequently use the information in these reviews to make hardware decisions.

Very comprehensive, thank you Ian!Of course now that you've exhausted so much energy on this review, the 1090FX chipset is right around the corner alongside the 2nd gen FX CPUs.
Such is life for a desktop hardware reviewer!
