They compare the portable Switch 2 to a Geforce GTX 750 ti which is about 1.4 Teraflops but they are talking about 17-19W power yet the Switch 2 only has a 20Wh battery and with a battery runtime at a minimum of 2 hours it can only use 10W per hour of which half that will be taken by the screen approx. So we are talking 4-6W per hour. They haven't factored in the small battery capacity into their analysis.
Also when Intel decided to call their 10Nm process 'Intel 7' it was due to Samsung's description of their process being 8Nm and yet Intel's 10Nm had greater transistor density and power efficiency so they came up with 'Intel 7' just to state their process was superior. Basically the Samsung 8Nm process is mainly 10Nm. I'm not sure how the TSMC process compares, I'm guessing not as over-stated as Samsung but not sure.
I've still yet to see any explanation on how the Switch 2 can provide 1.4 Teraflops of GPU performance in portable mode with such a fabrication process and only 4-6W per hour? Surely the 1.4 Teraflops figure is theoretical maximum power for short bursts nothing more. The reality will be much, much lower as an average. Trying to compare to original Switch it was claimed for a while that portable was 157 Gflops but some claims have it as just over 200 Gflops but from what I've read the reality was 90-140 Gflops in actual use based on what hackers/modders etc claimed. So in theory if the Switch 2 follows the same path it will be a lot lower in performance in reality than its theoretical maximum performance for portable mode (not docked).
Maybe this is why Nintendo are holding back sending journalists retail Switch 2's until launch day as journalists will be a little disappointed in overall performance. Yes I totally accept they are probably holding back units due to poor Switch 1 compatibility on launch hardware but it could also be performance factors too.
Poor dated/cheap fabrication process that is power hungry with small capacity battery. This is still what I'm waiting to be addressed in the Switch 2 spec. I've looked at loads of articles and yet nothing seems to be stated with regard how this works out. I still believe the Switch 2 Gflops figure for portable use will be far below 1 Teraflop in order to provide that 2 hours minimum runtime. I'm certainly happy to be proven wrong though.
