That's not the point. The point is, if you're going to make a smaller card, what's the point if you're not going to actually MAKE it smaller, in the end? Unless they expect people to use water cooling on these cards.



...no, if you're going to make a claim like that, you're going to need proof. If it were that simple, which is guaranteed to not be that simple, but if it were, then every GPU manufacturer would always make their PCBs small, because why spend extra money on more PCB when in reality, if it were smaller, you'd get a better performing card (temperature), with a lower cost, selling for the same price? This is how business' work, you can't just say "Oh well they just don't think about it", as that's nonsense. ANYTHING to save a buck and make your product BETTER is exactly what they would do.

I understand what you're saying, and i understand why you would think it, but the reality is, unless there's a review that shows you are correct, you plain and simple can't make statements like that as if you are correct without proof. Reality states you are wrong, due to my above statement.

And before someone goes and looks at temperatures of the fury card listed above vs other fury cards:

The only way to to a correct review to make a statement such as this something that is correct, is to use the exact same cooler, on both cards. You can't compare a small PCB with a 3-fan cooler vs a large(or regular) PCB with a different 3-fan cooler. That's not how testing works. You would have to get the exact same GPU, but one with a small PCB, one with a normal PCB, running at the exact same specifications and case setup and etc., and run them both with the exact same cooler.

Not that I see much point in arguing with you, but you seem to forget a few things. Most cards don't have HBM, so they need extra space for the memory modules and thus have to move the VRM further back. On a Fury, or Vega, there's really no point in doing that, since you have plenty of space to put a huge VRM-array where the memory modules usually sit. Actually, you want to have the VRM as close to the GPU as possible for getting better efficiency and transient response, so there's no need to extend the card to make it longer, as that area of the PCB would be completely empty anyway.

And yes, regarding air-flow, of course it's that simple, why wouldn't it be? Try to stick a piece of cardboard where the PCB ends to block airflow like it would be on a traditional card. Of course you would see temps and fan speed going up. There's a reason the Sapphire Fury's scored wins in most reviews in regards of noise and temps, despite being power hungry cards. Just go back and read the reviews. Not saying the short PCB is the only factor to the good performance of this particular heat-sink, but it's part of it.
