Ref boost 1.86ghz (as claim by the leak), OC to 2.1ghz. ~12% OC.

Ref spec is ~1.7ghz boost. It typically boost higher than ref paper spec, so 1.86ghz is believable.

2.1ghz, not believable for default non-OC state.
 
Not that impressive. The gains are purely from the node change, it seems. Probably not even.. TSMC FTW

NVIDIA's GeForce GTX 1080/1070 Announcement

'Most power efficient architecture we've ever built'
'16nm FinFET, GDDR5X 10 GHz'
'All games were running north of 60 FPS on a Geforce GTX 1080'
'Faster than 2x Geforce GTX 980 in SLI'
'Considerably faster than Geforce Titan X'
'Irresponsible amounts of performance'

Geforce GTX 1080 Specifications:
2560 Cuda Cores (GP104), 1,607 GHz Base Clock, 1,733 GHz Boost Clock.
Runs aircooled at 2,114 GHz - 65-67 C.
 
Given the performance and specs, I guess we can now confirm that there is zero improvement in IPC from Maxwell to Pascal (on average)

(2560 CC * 1733 MHz) / (2816 CC *1216 MHz) = 1.32

Announced performance improvement over 980 Ti is only about 25%.

We might even be looking at a regression in IPC (if 1080 boosts significantly higher than 1733 MHz).

That makes a lot more sense.

That's what I'm saying. Looks like they actually regressed per SP performance. Basically a shrunk Maxwell GM204 that clocks a lot higher while using more power.

nVidia's website says the ref is 1733 Mhz for boost.

Nvidia cards can automatically boost beyond the reference boost clock if thermal/power conditions allow. 2.1 GHz boost is super impressive but it was also on a single character render. It will be interesting to see if it can sustain that boost during normal gaming loads.
 
The reference cooler is channeling the Lamborghini Reventon. Not sure it's an improvement.

Amazing clocks and efficiency, look like they nailed the important parts.
