Performance results are really in favor of the Legion 5 Pro, and Lenovo’s engineering of this laptop really makes it an incredible option. Here’s a deeper analysis of the thermal behavior of the Legion 5 Pro: averaging around 79*C in our heavy game benchmark, we’re seeing an average of 1623Mhz from the GPU. Now let’s take a look at why we’re getting this significant boost in performance and see how much graphics power our GPU is pulling:
Here’s the performance chart of our Legion 5 Pro’s NVIDIA GeForce RTX™ 3070 graphics card. At an average of 79.6*C, our card is pulling 135W of power on average. To give this context, NVIDIA sets a 125W maximum budget for the RTX 3070 but will utilize DynamicBoost 2.0 to give up to a 140W boost as long as the cooling and CPU power budget permits it. Our GPU even boosts all the way to 160W in random bursts. This further explains why the esports games in our test showed some incredible numbers with the Legion 5 Pro. Let’s see some comparison with another RTX 3070-powered laptop that’s also aimed for content creators and professionals:
The other laptop shows a 99.61W sustained wattage. This equates to performance scores dipping up to 40% against the Legion 5 Pro. This is in exchange of only a 3*C difference which shows how a good cooling design can really shift performance in RTX 30 Series for laptops. Now for something extra, let’s compare with an external GPU dock:
An NVIDIA GeForce RTX™ 3080 graphics card is architecturally designed to do more in 1 watt of power compared to its smaller siblings. Now, this comparison isn’t so much about performance but rather cooling design. As an external dock however, it doesn’t share cooling capacity with a CPU. Its footprint also allows it to utilize a more compressed area for cooling. Still, it is only drawing around 120W of power despite a 150W limit.
