When we get either a single eight pin or six plus eight pin RX 480 we might see 1.6+ Ghz as they can modify the default power limit on the GPU.

I agree, more power and better cooling will do this chip justice.

It's not just more power though, it's the way the power is distributed on these RX 480s that limit them. I can see a greater efficiency when they address the power draw of the card. I think we could see 1070 performance for about 220 watts from the card. I'm reading reddit where people undervolted and could raise the max power target. Example they would move the default max power target to 100% of the current they can reduce the voltage required by the card. So this card is actually purposely limited probably for unlocked RX 480s later with better power distribution.

Max additional power is 50%.

Lowering voltage helps because it reduces power consumption and thus throttling. Not all cards can OC and undervolt at the same time.

I know that. I'm saying that if they 3rd party manufacturers move the physical max power limit of newer cards to 100% of what the default of the current is and we should see leaps in performance while also being able to dramatically lower the voltage. These cards are hard limited by their power design.

If the BIOS power limit is higher, there will be more watts available. Current cards at 150% power target have something like a 225w power limit.
The reference card does not run out of steam until 1400-1450, its the cooler that is limiting clocks to 1350 at the moment.

That being said, I would love to see a card with 225w default TDP with a max of ~300w. Then combine that with a good cooler or waterblock, the overclocking landscape should be interesting.

No, the reference card does run out of steam about 1350 on average, the guy who slapped a quality air cooler on the chip actually had to go through 4 to get his 1425Mhz sample.

Silicon lottery, god dam it.

Absolutely correct from my analysis of reading everyone's statements online. We shouldn't have to raise the voltage to get higher clocks on the GPU just it's power draw limit. Seeing it at 225 TDP would be spectacular. I'm more than certain we should be able to hit 1.6ghz with that.

That would make it ridiculously bad at perf/watt metric. Even Fury-X barely draws that much during gaming, and it's on an older arch, and process.

The difference is in memory. Plus there are some other variables at work here too. Switching to HBM would shave a lot of power consumption on the physical die of the GPU compared to the memory controller for GDDR5. NVidia saves power by using GDDR5x modules. It's not any faster but it's controller requires less voltage.

If the 14nm glofo node yield reaches maturity will we see less leakage and better overclocking?
