The Alienware and Razer models you listed also come with Optimus support or have Optimus support as an option. I don't think it has anything to do with Optimus or G-Sync. Both of those technologies can be enabled or disabled via software and their presence/circuitry contribute very little to increased battery consumption. Like I said, the reason laptops throttle when using battery is because the battery is physically only able to sustain a certain discharge rate before you risk the battery catching on fire. The brand and quality of the battery has a huge effect on how much the laptop manufacturer will throttle the laptop when using battery power. Additionally, how close the laptop manufacture will allow itself to get towards the battery's limit (safety margin) will have a big effect on that same throttling limitation.
I think you are beating a dead horse and barking up the wrong tree. Did you not read the quote and link I provided above? Around 100 watts is all that a battery-powered device is able to consume at the moment. ...Unless you add multiple batteries in parallel which are spaced far enough apart that they don't overheat next to each other; and then your laptop would be back to briefcase size and shape. 100 watts: not enough to reach full performance without throttling; unless you buy a "regular" laptop which never reaches a higher performance state because it only consumes that 100 watts max in any situation.
Small deviations in the performance level of gaming laptops which are throttling while unplugged are easily explainable by a myriad of things including:
- software optimizations and efficiency
- hardware optimizations and efficiency
- laptop manufacturer's choice of the battery brand to use and that accompanied battery manufacturer's battery limitations
- safety margin and how close a laptop manufacturer allows itself to squeeze that safety margin
- how accurately the laptop manufacture designs the laptop to monitor the battery and dynamically adjust the safety margin and throttling level to squeeze as much performance as possible without being unsafe (dimming display, reducing fan speed, and shutting off LED lighting may or may not increase performance depending on how closely the laptop manufacturer monitors battery consumption rates)
- probably other things I haven't thought about
Suffice to say, blaming Optimus or G-Sync doesn't seem like a very fruitful endeavor. In the grand scheme of things, I think it is unlikely that either Optimus or G-Sync contribute in a meaningful way towards how much your laptop throttles when using battery power and therefore doesn't affect benchmark score in any meaningful way in such conditions.
