No one can tell you you're wrong, but mobiles are way smaller than PCs, nearly all mobiles are smaller than GPUs, you won't encounter mobiles with a PC's performance until the mid-2020s
in 2025 smartphone hardware will be 2-4X more powerful than ultra gaming PCs of 2015, but they will never match the power of current PC at that time.
But they'd match a mid-end PC.
the new architectures are being designed are mobile first.
to elaborate on that, take Nvidia's Maxwell High end cores; when used in GTX 980 (GM204) it employes 2048 shader units, 128 texture unit, and 64 render output units.
In Mobile form factor "for Laptop" (GM204) Maxwell uses 1536 shader units, 96 texture units, and 64 render output units.
For Ultra mobile "tablets, smartphones" Maxwell uses 256 shader units, 16 texture units, and 16 render output units.
To see the big picture you need to start looking first at the ultra mobile version and how it scales up to mobile version with added SMM, and ultimately scales the full desktop version. put it in simpler terms the full desktop version is basically an ultra mobile part with more cores.
Currently the only two things that stops Nvidia from putting a Full GTX 980 in your smartphone are Heat, and Power concentrate. Phones have limited TDP usually 5-7W, a full blown GTX 980 got 165W TDP that would melt your smartphone, and consume your battery within minutes.
New advancements in Process node shrinks will eventually, will allow us to double the number of transistors on chip, thus putting more "cores" while maintaining same power envelope. But the desktop and the mobile counterparts will also get the same treatment meaning all 3 branches will keep on advancing as well.
Today The Tegra X, a mobile chip that can put in smartphones or tablets got 512 GFLOPS FP32 of processing power to put that in perspective that's equivalent to a desktop class Nvidia GT 640. While the GT640 can maintain it's performance due to larger thermal design, and power available, the X1's GPU will throttle much sooner to prevent damage, peaking only for short bursts.
I hope I was able to explain my point well, and did not bore anyone to death.
