[EDIT]hmmm.....whats going on at AMD? (and history of 3Dfx Rampage)

Now that there's a rumor that AMD might launch Vega way ahead of schedule (originally early 2017, now October?)..  it's probably getting Nvidia ready and prepared for this.  Nvidia's plan:  Launch Titan Pascal and possibly also GTX 1080 Ti (based on GP100) very shortly after AMD launches Vega.  At least NV would paper-launch GP100 without any trouble at all, since GP100 is already in production (quoted from Tomshardware:

The Tesla P100 is in volume production today and will ship “soon." Jen-Hsun Huang said that really means it will show up in the cloud first, and ship via OEMs in Q1 2017.

Traditionally, the flagship Titan / GTX xx80 Ti cards are clocked maybe 15% higher than Tesla variants.  I'd expect it to be clocked almost just as high as GP104 GTX 1080 - at least 1500Mhz core with 1600MHz boost for sure.  HBM2 memory might be clocked way higher than 1.4GHz as it's being refined, but I'd try to be conservative with that one - probably not more than 1.6GHz compared to 1.4GHz on the P100.

Notice how the GP100 actually has MORE than 2x as many trannies as GTX 1080?

Only 7200 million trannies, whereas GP100 has 15.3 billion.

What's interesting is that GP100 can do twice as many half-precision (FP16) textures as single-precision FP32 (unlike previous generations).  Would that really help with games if they have simpler operations that could use half-precision?

The GP100 based P100 has 3584 CUDA Cores. The chip itself has a turbo clock of 1480 Mhz. The total peak single precision performance of the P100 GPU therefore is 10.6 TFLOPs (3584 CUDA Cores x 2 Operations Per Second x 1480 Megahertz). Since we are talking about the exact same Pascal architecture here, we can directly compare performance of the GP104 based GTX 1080 to the P100.

The GTX 1080 on the other hand only has 2560 CUDA Cores. However, the card can reach clock rates of 2.1 Ghz conservatively and 2.5 Ghz on a liquid cooled setup. At a clock rate of 2.1 Ghz, the GTX 1080 is actually 10.7 TFLOPs of single precision performance! At a clock rate of 2.5 Ghz, the GTX 1080 will blow past the P100 GPU giving performance levels of 12.8 TFLOPs! That is an absolutely insane figure and roughly 20% faster than the P100. To put this into perspective that is almost twice the theoretical single precision performance of the GTX 980 Ti.

2.5GHz!?!???   This is insane, and unbelievable!
