    The RX 480 has been for sale for over a week now, but surprisingly we have seen very little custom boards. As one of the first MSI has now released official photos of its Gaming X version, the Twin F...

    That looks like an 8pin connector too :D

    bet it clocks the same as ref.

    Well, it has worse VRM for the GPU than ref so I doubt it will do any better. Cooling is obviously better but I don't think that is the biggest problem. The chip is already running near its max.

    Just by looking at those pictures, can you tell us how many Amperes are there for GPU?
    Or at least what is rating of those VRMs?

    I can say that PCB is bit too large and has way too much empty space. But I can't tell you if it has more stable power delivery than reference.

    Depends on the mosfets used, the original ones are extremely overspecced for the card:

    "We’d like to add one other short note. We’ve read here and there that AMD is using a much larger MOSFET than would be necessary on the low side (GPU side) with the MDU1511. The argument is that this results in massive overclocking potential.

    This component is capable of handling up to 100A, which means that every phase could be pushed to extreme limits, beyond 100W.

    The reason that AMD chose this particular MOSFET is probably completely different, though: it has a very low internal resistance of just 2.4 m***8486;. This minimizes loss in the power converters, resulting in both a cooler card and a lower power consumption. "

    100A!

    To me this MSI looks very "sexy".

    Also, cards with better cooling do overclock better:
    http://oc.jagatreview.com/2016/06/t...deon-rx480-ke-1-4ghz-dengan-cooler-3rd-party/

    As the original cooler is, well, quite awful.

    The RX480 ref 6-pin (3x 12v, 3x GND) is already wired like an 8 pin (3x 12v, 3x GND, 2x sense pins) connector as it doesn't use a sense pin rather that's grounded. Typical 6 pin is 3x 12V, 2x GND, 1x Sense

    I doubt the partner cards will have any significant advantage here coupled with the 4+2 phase VRM

    From what ive seen the polaris gpu gives back 100% of what you put into it,
    The clock speeds seem to walk hand in hand with the power usage,
    you dont get anything for free with this gpu,
    If you overclock this it will get hot but it will return performance.
    I think its better left alone and dont overclock it at all because right now its hitting the sweet spot in performance and price.

    I had a lot of ref cards(NVidia mostly) that at same voltage and cooling that would out clock customs.
    its still luck of the draw.but out of 5 or 6 7970's a ref pos was the best. better then matrix lightning all of them and 150 bucks cheaper
    why do you think they can get away with these lower rated power circuitry?
    the boards are low power they don't need beefy parts

    Agreed, I love the look of these MSI Gaming cards. Looking forward to reviews of these aftermarket cards.

    HAAA!
    Been telling this for years.
    Even if I didn't have nearly as much experience.

    But noooooo Saphire/MSI/Asus experts running their 27.3 MHz overclock keep telling me ref=pos.
    At least with ref you get what you paid for, and you know exactly what you're getting. At least till RX 480 :bang:

    3rd party cards are all about cooling and noise. Rest of it is mostly a silicon lottery.

    The PCB looks like a cut down version of another PCB, with mosfets and chokes missing. Do we know of off what it's based on?

    It looks like the same cooler and backplate as my 1070. It's nearly silent at load and keeps mine nice and cool. And aesthetically, nice looking (subjective, of course).

    If I were getting a 480, this one would be at/near the top of my list.

    Totally thinking the same thing. Recycled for sure. Glad I wasn't the only one seeing that.

    Probably from the 380x or 370?

    EDIT: just google image searched and its not from either of those. May be a new PCB just didn't need the extra.

    I don't think that google image search is that precise. The 380/380x would make sense as the sources for this PCB. I'm curious on how similar it is with the Sapphire one.

    No the chokes are between the IO and GPU socket on the 380/X card.

    Honestly it looks like a 760 PCB.

    Do you guys think these 6 phases voltage regulators will hinder overclocking potential a lot? How many did reference designs have, 10, or am I wrong?

    The voltage regulators are top class at least on the reference cards, so no.

    "Addendum about the Mega-MOSFET: Overclocking Heaven, Efficiency Amplifier, or Lifeline?

    We’d like to add one other short note. We’ve read here and there that AMD is using a much larger MOSFET than would be necessary on the low side (GPU side) with the MDU1511. The argument is that this results in massive overclocking potential.

    This component is capable of handling up to 100A, which means that every phase could be pushed to extreme limits, beyond 100W.

    The reason that AMD chose this particular MOSFET is probably completely different, though: it has a very low internal resistance of just 2.4 mOhm. This minimizes loss in the power converters, resulting in both a cooler card and a lower power consumption. This is definitely a step in the right direction, and it would actually even allow the PWM controller to distribute the loads asymmetrically."
