They didn't cost $200 though. tongue.gif

So if 480 hard launches on June 29th..I really hope `Ojoke`an hero`s and stops posting utter crap on this forum, like I`m hoping for that even more than for the latest peformance rumours about 480 to be true...and if they are true, I`ll be getting one for sure, possibly two.

Because they use bigger dies.

Even the ref pcb of the 480x kinda match the pcb of FE

How do you put a vapor chamber in that price tag...
I think it's more likely that it's just a tiny heatsink since there's not much heat to dissipate requiring a large heatsink.

I get what you're saying, but I highly doubt the vapor chamber costs that much to manufacture compared to the actual card cost. It may infact be a standard HSF with nothing more than copper-aluminum contact, and if it is, then you are right; this is one very efficient card.

I, too, believe that Nvidia has completely blown the cost of vapor chambers out of proportion. They are more expensive than a standard heatpipe/fin design, but the other thing you have to consider is that a heatpipe design is also much better at spreading out heat to a larger area, whereas a vapor chamber is much better at dissipating heat in a smaller area. In this case, because the PCB is so small, a vapor chamber makes more sense (if one is being used).

From a VRM standpoint, ref 480 has better power circuitry than 1070/1080, only slightly.

the HD4870 had a vapor chamber. tbh I don't it's that expensive.

Latest leak from chiphell, RX480 comes along with manual, 110W full load on gaming, the leaker is still waiting for official driver so no bench yet.
