The CPU did occasionally hit its a power limit throttle and thermal limit throttle. We will say that this isn’t the end of the story. In the morning we checked the GPU clocks and Cinebench results, and we found nothing had changed.ĭoes this mean the that some of the user experiences are invalid? No, but it means our particular unit had no overheating issues. We then let the Predator Helios 300 continue to loop Heaven overnight. Cinebench results were consistent, and after five hours, the GPU’s clock speeds remained consistent. Because graphics benchmarks rarely push the CPU hard, we also ran Cinebench using four threads to see how much performance suffered. To see how well the Predator Helios 300 holds up under a load, we cranked up the Unigine Heaven benchmark and let it loop for five hours while monitoring the GPU’s performance clock speeds. Scroll through any reviews of the Acer Predator Helios 300, and you’ll likely run across someone with stories of major overheating and falling performance. Trying to play any games off AC will drain this little battery lickety-split. Remember, of course, that your battery mileage will vary depending on how you use the laptop. IDGīattery life on the Acer Predator Helios 300 is a little underwhelming. We had the same complaint with the SE version. The higher-refresh-rate panel in the newer version will also tax the battery. Blame part of this on the battery size: at 48 watt-hours, it’s a fairly small supply. ![]() The result with the current Predator Helios 300 is slightly better than what the SE version of the laptop achieved, but still pretty below average overall. We charge the battery to full, unplug the laptop, and loop a 4K video until the machine shuts down. We set the PC in airplane mode to eliminate network interference, attach ear buds with volume set to medium, and set the screen brightness to a comfortable 250 to 260 nits. The performance of the Acer Predator Helios 300 is as expected in Rise of the Tomb Raider. Our last gaming test uses Rise of the Tomb Raider set to Very High in DX11 mode and, yup, it’s a tie again. ![]() The Acer Predator Helios 300 leads the pack of GTX 1060 laptops. We’ll call it a tie again-which is good news. Moving onto the performance of the GeForce GTX 1060, the Acer Predator Helios 300 doesn’t disappoint as we see it just barely edging out the other GTX 1060 laptops. It’s mostly a tie in our encoding task which takes about 30 minutes to run on six-core laptop. Set it to “gaming mode,” and it falls in line with the other 6-core laptops. It’s pretty much a tie here among similar systems, except for the Razer Blade 15, which was tested in its default mode. The task can take 30 minutes on a typical six-core laptop. For that, we use the free HandBrake utility to encode a 30GB video file. We also like to check the performance of laptops in longer tasks, to see how the CPU performs (and heats up) under stress. It’s a dead tie between the every laptop with a Core i7-8750H in it. You might think this is boring, but it’s actually a good sign for the laptop to be tied with every other Core i7-8750H laptop. Using Cinebench to measure single-core performance, we can see performance is right where you’d hope it would be. The multi-core performance of the Acer Predator Helios 300 in short-run multi-core tests is decent. As you can see, the current model’s score is just a pinch faster than the Special Edition’s score, and just a pinch slower than the Dell and MSI GS65-which all feature the same CPU. First up is Cinebench, which can show us performance in short multi-core CPU tasks. ![]() We’ll keep our performance somewhat abbreviated since it hasn’t changed much. The ports have not changed from the original 7th gen Core i7 version of the Acer Predator 300 as you get plenty of ports (albeit no Thunderbolt 3.) Acer Predator Helios 300 Performance
