Six A75-Based Motherboards For AMD’s A8 And A6 APUs

By Thomas Soderstrom

Advanced on-board graphics put AMD’s Llano-based APU far ahead of Intel’s Sandy Bridge architecture, at least when it comes to 3D apps. But you’ll still need a new motherboard to support the Socket FM1 platform. Today we test six affordable contenders.

AMD was fresh out of A8-series APUs by the time this editor needed one, but the lower price of its A6 series makes the runner-up an attractive option for buyers in the $100 motherboard market.

Rosewill’s FORT120 might not be available on the market any longer, but it has proven itself the perfect cooler for our socketed AMD processors. Anyone envious of this older model can find similar performance from the similar designs of other manufacturers.

G.Skill’s 16 GB DDR3-2200 kit provided the four super-fast DIMMs needed to assess memory overclocking capabilities. We set these to DDR3-1600 CAS 9 for remaining benchmarks.

After determining that our 80 PLUS Gold-rated 760 W Seasonic power supply was 84% efficient at a mere 2.5% load, this editor decided to use it in every possible review.

We included a few games in today’s tests to gauge the benefit of improved memory with AMD’s integrated GPU.

    Thank You for the Review. I am glad to see you guys taking this and pushing it to the limits. Can't wait until SB-E and Bulldozer reviews.

    Qne question, what does the APU,( either the A6 or the A8), have on F@H applications?

    I know F@H is a great cause, might cure cancer etc, but wouldn't it be more geeky to search for radio signals of little green men?

    what about blue-ray playback? and power consumption when playing it. I'm planing a HTPC. And those small form factor are really appealing. especially Gigabyte’s A75M-UD2H, I will get that one.

    I checked the CPU reviews and didn't see anything there either. You know it's going to be low utilization for these processors, which means it will be closer to the idle power than to the full-load power...

    I remember when the Gigabyte board first was launched, I though it looked pretty sweet then even posted a poll on it. I'd have to agree, it seems like the board to have for A8. Looks good too, although I a find Gigabyte's non-blue/white scheme offerings more attractive. Just ordered my 990FX UD5, can't wait!

    I think micro atx fits into plenty of SFF cases. Maybe we need to redefine..

    I'd like to see a showdown of mini itx boards though, I think Anand did something like that recently. That's probably where the A8 CPU's need to go head to head with atom anyway, most reviews I've seen show the CPU's aren't all that cut out for desktop. Maybe the next batch that comes out in Q4/Q1 2012 will be better for desktop.

Dude you got this QUAD CORE based on the phenom II architecture mixed up with the e-350 or the c-50 those are the ones that are going up against Atom.

    buzznutI think micro atx fits into plenty of SFF cases. Maybe we need to redefine.That would make you part of the problem rather than part of the solution.

    1.) SFF originally stood for Shuttle Form Factor and was proprietary, using 2-slots.
    2.) It was copied by companies like First International Computer and AOpen
    3.) AMD established a standard for "open architecture" systems of similar design, called DTX.
    4.) ITX is smaller than DTX and fits DTX cases.

    Notice this has nothing to do with Micro ATX. People who claim that anything shaped like a cube is SFF need only be shown a full ATX cube before they start making excuses. People who point to horizontal cases and say SFF need only look at ancient AT desktops before they're forced to come up with excuses.

    2-slots. That's what makes Shuttle copies different from everything else. Cubes can be any "size", HTPC's can be any "size", if SFF is a size standard it can only be used to apply to two-slot cases.

    Some competitors have been trying for years to expand the definition of SFF. They are, of course, wrong.

    Nobody's perfect, one of Tom's old team members once said that barebones always refers to SFF systems (even though full sized barebones existed long before SFF). But at least Tom's tries to fix those types of errors rather than force them into the vernacular.

    I'm just asking people to be specific. If you mean cube, say cube. If you mean desktop, say desktop. If you mean mini-tower, slim tower, or slim desktop, just say it. Then apply a form factor "Mini ITX slim tower" or "Micro ATX desktop". And if you're saying "SFF" rather than media center, well it's obvious that SFF can do other things so just be specific and say media center.

    If you're not specific, you might find yourself in a discussion about what the meaning of "is" is.

    I have the gigabyte board and undervolted by .2 running stock speeds. Its used for my HTPC setup so for me making it silent and less power draw were the key points. I have an oversized fanless heatsink and never have issues. When I do run a game on it for fun, the case fan will kick up, but watching movies it stays silent.

    Would love to see some benches on the gigabyte with those max overclock numbers as the GPU would benefit greatly from the memory oc.

Tom's Hardware is working on a memory article using one of these boards, and has included games in the test!
