@ronvalencia: any idea what the wattage drop would be by converting the X1 to use 16nm FF compared to using an X2 at 16nm?
depending on the form factor of the device it may need to also go even lower than 5W. the battery will have to power the SOC, wireless, the screen(s) (i dont think itll be dual screen though) speakers and other bits n bobs. i wonder how they will get it down?
Shield TV(TX1)'s 20 watts power consumption was too high for 8-to-9 inch tablets hence why HTC Nexus 9 has TK1.

TEST2 : CUDA Smoke particle demo
- Power Measurements:
- Base : 0.62A ( 7.53W)
- Peak : 0.91A (11.06W)
- Observed Avg. : 0.88A (10.69W)
- Avg. Less Fan : 0.81A ( 9.85W)
- Avg. Less Sys : 0.71A ( 8.26W)
This is for the entire tablet system.
Single Precision Peak: 326 GFLOPS
Single Precision SGEMM: 290 GFLOPS
1 to 5 watts is for candy-bar size smart phones.
For comparison, Intel Atom Processor Z3740D SoC for Dell Venue 8 Pro (8 inch tablet) has a typical Scenario Design Power (SDP) of 2.2 watts.
The current Tegra X1's power consumption is too high for 8 inch tablets.
Using the same Xiaomi-Mipad/TK1's power consumption profile, the shift from 28 nm to 16 nm FinFET could yield 2X TK1 i.e. a 384 CUDA processor solution which is effectively close to 20 nm TX1's 256 CUDA core count (512 GFLOPS 32 bit).
You are looking at NX solution around 500 GFLOPS, if they keep Xiaomi-Mipad's power consumption profile.
If Nintendo aims for 3DS's ~4 watts power consumption profile.... perhaps 250 GFLOPS solution.
NVIDIA couldn't battle Qualcomm or Apple on premium low system power and perf/watt price, hence NVIDIA is playing the "AMD role" against Qualcomm or Apple.
NVIDIA is not transparent with their Tegra power consumption.
