Back2Gaming proudly partners with OCCT for this test to allow us to set various stress loads. OCCT allows granular control on testing and provides options to configure and control stress loads on a per-core level. It also features monitoring and logging for troubleshooting problems and performance analysis . OCCT is available for free for all users with a paid version for power users and businesses.
This stress test goes through different workloads with 5-minute breaks in between. The loads run for 10 minutes and goes through SSE, AVX and AVX2 workloads. The last test is a combined CPU and GPU test which should push our unit to a very intense loading scenario which should show us a good indicator on the peak load temps of this laptop.
For game stress testing, we use Final Fantasy XV Benchmark at 4K High Settings. FFXV Benchmark is highly repeatable and puts a decent amount of realistic gaming load on the system. The benchmark runs for around 5 1/2 minutes and data is logged via NVIDIA Frametime.
OCCT CPU/GPU/Combined Load Behavior
This is a 50-minute test which sees a CPU AVX2 test at the start followed by a GPU test and then a combined test. There are 5-minute breaks in between to let the cooler settle. This is shown via the different behavior segment on the charts above.
This test shows us how the CPU and internal GPU affects each other. We see the CPU reaching 90*C on occasional spikes with an average of 80*C on our 1st-segment CPU-only load. The combined load sees lower dips in CPU temperatures.
Final Fantasy XV Benchmark 4K Gaming Load Behavior
The charts above show us the GPU-only numbers for the ROG Flow Z13 and the XG Mobile GC31 and GC32L. Using only the RTX 3050 GPU, the GPU oscillates around 40W.
Bringing in the XG Mobile GC31 with an RTX 3080 which peaks at around 120W but settles closer to 100W. Now comparing it to the new GC32L with a Radeon RX 6850M XT, we see that ASUS manages to tame this GPU much better with a lower average temperature of 76*C at a tight 99W consumption.
Take note that the XG Mobile needs to be purely powered off the wall to function so both power draw really don’t play a role in power consumption but the RTX 3050 dGPU does. It also plays into the overall thermal behavior of the Flow Z13. Its understandable why on a combined test, the Flow Z13 drops clock speed to really hit that power envelope.
