The Price: Around $100, The Motherboard: MSI's E350IA-E45

AMD expects most E-350 motherboards to sell for around $100 in etail. For lightly featured boards, I've heard this estimate is about right. It's once you start adding WiFi, passive cooling and other enhancements that costs creep up to around $130. Even at $130 that's not a bad deal. We're talking about better pricing than most ION boards but with much better performance.

AMD sent over the first Brazos motherboard ready for prime time, MSI's E350IA-E45. The mini-ITX board features two DDR3 DIMM slots (a Brazos feature, there's still only one 64-bit memory channel off of the APU), four 6Gbps SATA ports and a PCIe x16 slot (electrically x4). On the I/O panel MSI provides both VGA and HDMI out for video. For audio you have the options of running audio over HDMI, coax, optical or 1/8" stereo outputs. There are a surprising number of USB ports on the back of the board: 6 x USB 2.0 and 2 x USB 3.0 driven off of the very familiar NEC D7202 USB 3.0 controller. There are two USB 2.0 headers for front panel or case USB as well. There's unfortunately no WiFi support on board, all you get is a single Realtek RTL8111D 10/100/1000 ethernet port.

The MSI board doesn't support overclocking, so all results are at the CPU's stock 1.6GHz frequency.

Power is supplied by a standard 24-pin ATX PSU connector (older Atom/ION boards sometimes only used a 20-pin connector) as well as a 4-pin ATX12V connector. The Hudson FCH is passively cooled while the APU features a small, and unfortunately audible fan. ASUS is working on a passively cooled E-350 motherboard which I should have within the next week.

    It would fail at bluRay 3D.

    the 1080i is a bit unimportant since flatscreen TVs don't do interlace.

    if i remember correctly, nano runs 1.8ghz and is much faster but more power hungry...

    are there netbooks with nano anyway?

    I'm sold on this Sandy Bridge / Atom killer. Well, maybe not Sandy Bridge killer yet, but i'm sure the second generation fusion processors will be. Now I need help finding a great little mini-itx case. I'd love to build a mini pc the size of my Wii. I have found a few small cases, but where on earth are the slot feed DVD/BD players. I always start my daily reading right here @ Anandtech.com so please save me some time and help us all out by rounding up a case review for this new Fusion platform. Go AMD Fusion - Boo Intel (and your 1$Billion oops!)

    Sure is such excitement over such a tiny chip.

    It also reminds me why one of the P4s Dells I use at work is sooooooooooo Slooooooooooooooow.

    I'll admit I'm using my very old computer (AMD X2 3800) as an HTPC somewhat, since it wasn't worth selling when I upgraded. But its a 90watt CPU... so saving power is the big thing, eh?

    I've got an Acer Aspire 5517 with an AMD Athlon tk-42 processor and integrated HD3200 video. It's also 1.6 Ghz so I wanted to showcase a relative clock for clock comparison. It is a 20W chip with 1meg cache built on a 65nm process and no VT. It's not an Athlon II, just an Athlon 64 x2, I believe.

    On Cinebench R10:
    Single Thread: E-350=1174, TK-42=1340 :-: 1174/1340 = 87.6%
    2 Threads: E-350=2251, TK-42=2373 :-: 2251/2373 = 94.4%
    (1174+2251=3425)/(1340+2373=3713) = 92.2%
    Scaling seems better on the new chips than on the older ones.

    At idle with the screen off the laptop pulls about 18 watts. In Cinebench on a single thread it pulls about 30 watts, with 2 threads it pulls about 33 wats. Opening the screen to run the LCD at full brightness adds about 9 watts at any time.

    I ran these tests with a Kill-A-Watt meter. It's not quite an exact comparison, but is pretty close. But to see that they kept performance close, added graphics, and still managed to shave 10% off TDP it's pretty dang impressive.

    Actually, I just let my laptop sit idle for a while. Now, idle power usage dips down to 11 watts with the lid closed and generally stays switching between 11-13 watts. Hmmm, the power usage on these new chips aren't quite as I would expect unless it's a platform thing. This article shows that the new chips pull 9W at full load under Cinebench. My testing shows I ramp from about 12W up to 33W which is a 21W increase by taxing the TK-42, right inline with the 20W spec giving my rounding of numbers. All other parts being equal and I only ramp up 9W instead of 21W then my peak should be about 12W less, or about 21W total instead of 33W total. That would be a significant gain. Interesting that this article has the new platform at 32.2W with the same workload. That's about 50% higher than my rough estimations. Is it because it's a desktop board and not a laptop design?

    Thanks for the performance comparison. I really helps putting the Zacate into perspective.
    On the power consumption comparison:
    Ofcourse the desktop board system will consume more than a laptop with same specs.
    Your laptop consumes less because of different PSU , less USBs , less components in general (PCIex) and so on.
    So in order to make a correct comparison , wait for a HP DM1z review for example.
  • lovansoft - Wednesday, February 2, 2011 - link

    I figured as much, but 50% seems high. But then again, it really is only a few watts... Lower efficiency PSU, a couple more chips to provide some extra ports. A couple of watts here and there do add up I suppose. And to think it provides more than 90% of my current performance into only 2/3 the power. I'd think if they can up it to 2Ghz it'd be about the same as mine without tapping the power too much. From the speculation I've read, it makes it seem that the revision coming in a year should grow the performance by quite a bit without really increasing power, about what you'd expect from a die shrink.

    You know, with this architecture, it'd be nice if a board could be made that would have multiples of these chips for server use. From my experience in SMB, I rarely find servers being CPU bound. Usually if they are, then there is some runaway process that needs to be tamed. Maybe this current generation isn't quite fast enough, but with a process shrink and some speed adjustments, getting a few of these on a board would make a very low energy server. But it'd only be feasible if there were something they could use that built in graphics portion for. Otherwise it'd be a waste.

    Oh, and Cinnebench R10 on an AthlonXP 3000+ (2Ghz) = 1438.
    Single Thread: E-350=1174, XP3000=1438 :-: 1174/1438 = 81.6%
    1.6/2=80% Seems to be about the same IPC as the AthlonXP line.
    I don't have power numbers for it, though.

    Is E350IA-E45 board HDMI 1.4? Info on the net is confusing.
  • Hrel - Thursday, February 3, 2011 - link

    that VIA chip is pretty impressive.
