Made. Ive got the GA502DU model, so theres a Ryzen 7 3750H quad core CPU Nvidia GTX 1660 Ti Max Q, graphics, 16gb of memory in dual channel and a 120Hz 1080p screen.. You can find up to date. Prices linked in the description.. The Zephyrus design is traditionally known for raising the back of the machine up when the lid is opened to aid with air flow. However, that feature is not present in this more budget friendly design.. There are some air vents on the bottom. However, interestingly, the sections that are actually above the fans are blocked off, so it may primarily bring in air through the keyboard and with the vents. Just above it. Inside weve got a few heatpipes with a couple shared between the processor and graphics, and we can see that air is exhausted out the side and back with the left fan and just out the back for the opposite. Fan., The ASUS Armory Crate software allows you to change between three different modes: silent performance and turbo and Ive tested all three out here.. Basically, these modes adjust maximum fan, speed, CPU power limits and control, GPU overclocking, as defined here.. You can easily swap between these modes through software or by holding the function key and pressing the pressing F5. The key with the fan icon. Thermal testing was completed in an ambient room temperature of 21 degrees Celsius so expect different results in different environments.. No CPU undervolting has been done as this is not currently possible, with AMD mobile CPUs.

At idle. Both the CPU and GPU were on the warmer side, though realistically not a problem and the fans were quiet as youll hear later.. The rest of the results are from combined CPU and GPU workloads and are meant to represent worst case scenarios, as I ran them for extended periods of time.. The gaming results towards the upper half of the graph were tested by playing Watch Dogs 2. As I find it to use a good combination of processor and graphics., The stress test results shown on the lower half of the graph are from running the Aida64 CPU stress test, with only the stress, CPU option checked and the Heaven GPU benchmark at max settings at The same time to fully load the system., Starting with the stress tests in silent mode, the 1660 Ti max q was thermal throttling at 86 degrees Celsius.. If we change to performance mode, the GPU thermal throttling is removed. As this boosts the fan speed. However, the CPU was now hotter, as this mode raises its power limit. I think it was thermal throttling. However, hardware info doesnt currently report on this for the 3750H CPU, so I cant say for sure.. There were no differences in temperatures with performance or turbo mode because, as youll hear later, the fan, speed, didnt, actually change in this workload. Using a cooling pad did help a little, despite the vents directly above the fans being blocked off by the bottom panel.

As we saw earlier., The gaming results saw a similar trend with some GPU thermal throttling in silent mode, with slight improvements to thermals, as we continue making changes.. These are the average clock speeds for the same tests. Just shown. In silent mode were seeing lower. Cpu clock speeds compared to the other tests as this mode caps the CPU power limit to 8 watts.. Although the clock speeds in watch dogs 2 look good here, the game was actually unplayable but well check out some FPS benchmarks with different modes soon. In performance mode. Theres, a nice boost to CPU clock speed, as the power limit raises to around 21 watts, and the GPU sees an increase too, as this boosts fan, speed and removes thermal throttling., Turbo mode saw no change to CPU performance due to suspected CPU thermal throttling. However, the reported GPU clock speed raises due to the overclocking turbo mode applies., As there was more thermal headroom for the gaming test. The performance and turbo modes are making more noticeable improvements.. The cooling pad makes a big improvement to CPU clock speed, while under stress test. As it helps address the CPU thermal throttling, however, it hardly did anything while playing this particular game as temperatures werent too bad without it.. These are the TDP values during these same tests., Ive used hardware info for the GPU shown by the green bars and were not hitting the 60 watt power limit of the 1660 Ti Max Q, with silent mode enabled, due to the GPU thermal throttling covered earlier.

Hardware Info still seems to incorrectly report the TDP for the 3750H CPU, so Ive used AMDs uprof tool instead, however, as this didnt really give an average over time, these results are only approximate values.. I dont have results for the gaming tests because without a consistent load, it was difficult to report an average.. The 3750H has a 35 watt TDP and, as this is only hit once the cooling pad is in use, it sort of implies that we were thermal throttling in this workload. Without it, though, as we saw, this seemed to be less of a problem with an actual game running., These are the TDP values I was seeing reported by uprof, while under a CPU only workload, so it looks like performance mode. Has a 28 watt limit, though this was not being hit under combined CPU and GPU loads, as we just saw before due to thermal limitations.. These are the average clock speeds under these same workloads as the power limit increases, so does the clock, speed and performance. More power and performance typically equals more heat. However, we saw the highest temperature in silent mode simply because the fan speed was so much quieter when compared to performance or turbo modes.. To demonstrate how this translates into performance. Ive got some Cinebench CPU benchmarks with Intels last gen, i5 8300H quad core CPU in red. Just for comparison, though, keep in mind, the i5 does have a higher 45 watt TDP limit.

Ive compared these two in a separate video if youre interested in more comparisons.. So how do these different performance modes actually affect games? Ive tested a few games with silent performance and turbo modes to find out. Battlefield 5 was tested in Campaign mode at ultra settings., With silent mode enabled it was still quite usable. The 1 low wasnt too different to the other results, and it was only around 15 FPS lower compared to turbo mode with much louder. Fans. Shadow of the Tomb Raider was tested with the built in benchmark at highest settings.. Again, there wasnt much difference to frame rate between performance and turbo mode. However, silent was a fair bit lower. This time., Far Cry 5 was tested with the built in benchmark at ultra settings.. In this test there was a much larger drop with the silent profile in use and, like I mentioned before, I couldnt play watch dogs 2 in silent mode, so it seems to vary by game. Basically, I wouldnt rely on silent mode for quieter gaming.. I did test these games at max settings, though theyll likely be more playable with lower settings.. If you want to see more gaming benchmarks on this machine check the card in the top right, where Ive tested 20 games at all, setting levels.. As for the external temperatures, where youll actually be putting your hands at idle, it was a bit warmer than the standard 30 degrees. I usually see, though, only in the center towards the back.

, With the stress tests running in silent mode, its in the mid 50s. In the center getting up to 60s right up the back where it was hot to the touch granted, you wont be touching here. In most cases, anyway., It was a bit cooler in performance mode, as this also raises fan speed, and we can see the cooler spots on the left and right where the fans bring in air through the keyboard.. There wasnt too much difference in turbo mode still getting to 60 right at the back, but again for the areas youll actually be touching its not too bad. Heres. What the fans sound like during these different tests. At idle in silent mode, the fan was only just audible. With silent mode and the stress tests running its much quieter compared to most other laptops. Ive tested and as we saw some games were playable in this mode. But you could always customize fan speed to find a sweet spot, thats playable without being too loud. In performance or turbo mode. The fan speed was the same and pretty average when compared to most other gaming laptops that Ive tested.. I forgot to test fan speed while gaming and although it will vary by game, I did notice that, while in performance mode, the fan speed did drop back a couple of decibels when not being smashed with a stress test.. Overall, the ASUS GA502 gaming laptop doesnt appear to run that hot, at least purely in terms of internal temperatures.

. Granted it does thermal throttle on the graphics if you run it in silent mode, but as we heard, the fans were significantly quieter in that mode. So thats going to be expected.. This is only the second AMD laptop with Nvidia graphics, that Ive tested. In general Ive found AMD CPUs to run cooler compared to Intel based laptops that easily run anywhere from 90 to 100 degrees Celsius under the same load. However, this is because the Intel CPUs have a higher 45 watt TDP and, as we saw this results in increased performance too., It appeared that there was thermal throttling on the CPU under worst case stress test. However, when actually playing a game, it seemed alright, but this will depend on the specific game and workload. I say appeared because I dont actually know any software that correctly reports thermal throttling on AMD mobile, CPUs Im. Just basing this on the results. I saw 89 degrees as a maximum average. Doesnt seem too high though. Using a cooling pad, helped address this and improve performance in terms of clock. Speed, though it may have been more effective if the bottom air intakes werent blocked off its hard to say for sure. Without damaging the bottom panel to remove the plastic., It may be possible to further improve temperatures by swapping the thermal paste. However, as this is a review unit that I have to send back Im not able to change the paste, otherwise, the next reviewer will unknowingly report different results.

Due to what Ive, done. Raising fan, speed and using a cooling pad are much easier for most people to do than changing paste anyway and as weve seen, these tweaks did help improve performance and temperatures with the GA502..
