Aliens vs. Predator Benchmark
Aliens vs. Predator is a DirectX 11 science fiction first-person shooter video game, developed by Rebellion Developments. Available as a standalone benchmark, on default settings the benchmark uses 1920x1080 with high AF settings. Results are reported as the average frame rate across 4 runs.
As with most of our results, the differences are minuscule. There is only a 0.3 FPS difference between this motherboard and the top motherboard.
The motherboard appears to be able to hold its ground against the A75 chipset.
Metro2033
Metro 2033 is a challenging DX11 benchmark that challenges every system that tries to run it at any high-end settings. Developed by 4A Games and released in March 2010, we use the inbuilt DirectX 11 Frontline benchmark to test the hardware at 1920x1080 with full graphical settings. Results are given as the average frame rate from 10 runs.
There is very little difference between this motherboard and other motherboards which cost twice the price.
Metro is a very demanding game and the board does well to keep up with other more expensive motherboards on the market.

Isn't FM1 on the way out with Trinity's upcoming release?HW_mee - Thursday, March 22, 2012 - link
Yes it is, FM2 is the next socket for desktop Trinity, but I have not ben able to find any information on compatibility between FM1 and2.Some rumors claim that the current chipsets will work with the FM2 socket, but no info an the processors :-(
Feel free to add more rumors/info :-)

I thought I read that AMD had one last upgrade for FM1. It was assumed (hoped) they meant Trinity.Not sure what FM2 will offer that's different. Maybe add more memory channels?

Again with 1000w+ power supplies on systems designed to use 50-100 watts...No power supply manufacturer will optimize its power supplies to have good efficiency below below the 20%, which is what 50-100 watts will be on this 1250w psu.
As you can see on techpowerup.com/reviews/OCZ/ZX_1250W/5.html this power supply has 66% efficiency at 65 watts and 75% efficiency at 90 watts.
"These are the real world values that consumers may expect from a typical system (minus the monitor) using this motherboard."
No, they absolutely are not. Even if customers would buy cheap 350-500w power supplies, those would do 80% efficiency at even 60 watts load.

And who the hell is going to buy a 130$+ video card such a factory overclocked Radeon 5850 when the motherboard is supposed to targeted to value users?Value users are going to either use the integrated video card (why no power consumption values WITHOUT a video card?) which is good enough to watch movies or even play games like World of Warcraft or they're going to get something like a sub 100$ 5750 or a 6750.
It doesn't make a big difference at idle, but it sure does at high loads, and some people are just concerned enough to compare power consumptions and lean to a solution or another based just on this.

Yeah, this is standard, as the "anand" testbed and it has to be as similar as possible across all the systems they test from i7 3960X to an E-350.I do not accuse anand of foul play, but it is not really a fit setup for mid to low performance systems.
If you want a proper look at Llano, Brazos or similar and what they offer in a "daily" scenario, you can try looking at the SPCR reviews of these platforms.

Well, they say it's to make things comparable. But then they have power consumption charts where some systems use different components than others. And they don't put it in the chart.So one system was tested with a Radeon 5870 (low idle) and Windows 7 and another system was tested with a GeForce GTX 285 (~20-30w higher idle) and Windows XP and they don't mark it on the charts.
Typically they misrepresent AMD that way.
Has to be said.
I haven't used AMD (on the cpu side) myself in a long time, but I feel they are getting an undeservedly bad rep on tech sites.

I don't buy it. I understand the concept but I don't buy it.Such a popular website like Anandtech with reasonable income from advertising can very well keep 2-3 power supplies for tests, in order to provide accurate, correct reviews.
A 600w power supply is good enough to run benchmarks on virtually ANY processor and single video card combination, even when overclocked.
With 2 or more video cards, you can very well change the power supply to a 1000w+ one.
Changing power supplies takes minutes on a test bed.
Anandtech could also just buy a batch of power supplies from the same series (to have a few as backup in case one or several break) and put them through a load tester, to get the efficiency graph, one similar to the one in the Tech Power Up article I linked.
From that point, as they have the efficiency graph, they can just measure the power consumption at the wall and estimate how much the system actually uses.
It won't be 100% exact as the ratio between 3.3v, 5v and 12v rail usage will vary between systems, but as 12v is a large percent of usage nowadays, it will be within a few percents. Close enough.

I do not like it either, but remember that Anandtech is not written by people in on physical location.I know some of the contributors are located in different parts of Europe, and I am pretty sure they have some people scattered across the US as well. They cannot ship the same equipment between all these locations and it looks like they have purchased somewhat similar equipment for use in their test.
This 1000 watt supply is then a part of the "testbench" and you will have to visit other sites for for more realistic power/efficiency numbers when reading a review of a part that is not high end.
mariush - Thursday, March 22, 2012 - link
ಠ_ಠThis is just another point for computing the efficiency graph of the power supply and report the estimated real usage of the system
We all know efficiency of a power supply changes when running from 110-120v (us) compared to running from 230v.
The 65w idle on 230v in Europe can very well be 70w in US, due to less efficiency when running on US mains power.
It would be more honest to report the actual consumption, after factoring losses in psu.
