This topic it’s about studying a visual delusion this relative to number of MOSFET present at different PCB dimensions all hosting identical GPU chip.

 A larger PCB and double amount of MOSFET they can be justified when the plan this is all MOSFET to be used this time exclusively as heat spreaders over the larger PCB.

It is unfortunate that PC hardware reviewers them missing electrical training, they translate a larger count of electronic components as this to be a performance indicator.

NVIDIA this offers power limiter in their GPU as safety valve and not as performance binning or a deliberately made FPS performance limiter.
NVIDIA use the number of active transistors within in any GPU as performance indicator, or at a reversed point of view as this to be a TRUE FPS limiter.
NVIDIA Chips classified as Ti, they include higher count of active transistors and power delivery system this should be enforced too, such a design it is justified to have higher count MOSFET by one or two stages.
     
Naturally the ones having as hobby to OC anything, their worst dream at night this is the NVIDIA power limiter along with GPU temperature sensor.

But from an consumer point of view, neither an double or triple amount of MOSFET along their necessary support components (more coils and capacitors) it cannot justify 40% of higher price in comparison to normal dimensions ITX compatible VGA card.

At electronics product design all engineers they are daily challenged to use their intelligence so to fight back thermal issues or power supply issues, by the use of fresh ideas with minimal production cost impact.

Any overload of power supply circuitry will become a boomerang by this now causing increased PCB temperature and GPU this eventually will restrict it clocks again.

In the end of the day, one card with higher count of power circuit components this is designed to deliver a small percentage of higher GPU clocks due the fact that PCB alone this has now an increased heat dissipation factor over the normal ITX card dimensions.

But actual performance increase at FPS this will be minimal and approximately not more than 1.5 FPS as best.
Production of single FPS this translates to specific count of transistors working as horses pulling a wagon at the unit of time.

Forcing a specific known amount of horses those running at highest pace this is always ineffective.
A higher 3D Graphics load, this it does require more horses to pull the wagon and also wagon top speed this will increased eventually when load this is get wisely distributed at more horses.
