1947 score with 1.216 V @ 4.3 GHz day to day settings, with possibly the slowest low volt RAM in existence. This G3258 would have to step up to 4.5 GHz, to match Skylake single thread score at 4.2 GHz. Which is 7.8% better per clock for this benchmark it seems.
But the exciting part is the voltage at 800 GHz,
0.548 V. That is an Adaptive Voltage, Offset Undervolt that no 350$-1100$ CPU can do, something only CPUs with a low default base frequency can achieve. You can and should set an offset undervolt more power efficient than many of the notebooks out there, while also having an OC to match or almost match like in my case the single threaded responsiveness of Skylake.
