Here's the general rundown for the specific components compared to what Dolphin wants & what your system has.
* Processor -- AMD A10 Pro-7800B -- NOT RECOMMENDED, Potential Performance issues.
Dolphin devs recommend a quad-core processor (as the emulator utilizes 2 core, leaving the other 2 cores for background & OS work) & typically recommend Intel Core i5 or i7. For AMD processors, they tended to have performance issues with Dolphin UNTIL the Ryzen series.
While this is more a discretionary deal... you may run into potential problems here.
* RAM: 8 GB's -- EXCEEDS REQUIREMENTS
Dolphin requires 2 GB's of RAM... which any computer running a modern version of Windows will likely exceed ( 2GB's is the bare minimum. 4 GB's being minimum recommendation & 8 GB's being recommended for gaming).
* Graphics Card: AMD Radeon R7 240 -- NOT RECOMMENDED, Potential Performance issues.
Dolphin devs note that AMD cards favor Direct 3D (D3D) over Open GL (OGL), but low-end & aging graphics cards (6+ years old) may have problems. Your graphics card should support Direct X 11.1 or Open GL 4.4 (preferably both) to do well.
The Nvidia GTX 1050 is ~350% stronger by comparison, being considered a basic current-gen card.
Going with something release around the same time, a Nvidia GTX 860M (utilized by the Alienware Alpha R1) is still ~158% stronger compared to your graphics card.
Even going with the GTX 660 (an old graphic card used as a baseline) is still stronger (~280%) compared to your card.
Please be aware that I'm using UserBenchmark.com for these comparisons, so the figures are subject to some discrepancies... but are reasonable for rough figures for performance.
OVERALL ASSESSMENT: NOT RECOMMENDED, MULTIPLE Potential Issues...
Your Graphics card is pretty low-end AND you have a non-Ryzen processor, so you'll likely have problems properly executing the game code despite your processor's good clock speed. While my assessment could be incorrect, you should temper your expectations... just in case.
