Gaming performance for Intel Arc Alchemist GPU unlocked by switching off one feature

The Intel Arc Alchemist A350M mobile GPU doesn’t seem like it should deliver serious gaming performance, but it was recently discovered that disabling a single feature could do just that.

The feature in question is Intel’s Dynamic Tuning Technology (DTT) driver. DTT works by “automatically and dynamically allocating power” between the CPU and GPU, which is supposed to help preserve laptop battery life.

However, Korean YouTube channel BullsLab Benchmarks tested a Samsung Galaxy Book2 Pro laptop with an A350M GPU and DTT disabled. Testers found that while thermals and power consumption skyrocketed, gaming performance also increased.

The A350M hits a maximum power limit of 30W and a maximum frequency of 2.2GHz, but to save power DTT seems to throttle the GPU. Disabling DTT removes this limitation, allowing near 100% GPU utilization.

Tests also showed it to be around 30% faster than the Nvidia GeForce MX450 with a TDP under 20 watts. There’s also a massive fps boost, with up to 80 FPS once TNT is disabled.

Currently the Intel Arc Alchemist A350M is not available outside of Asia and Oceania but hopefully that will change soon as we would love nothing more than to get our hands on one for test it by ourselves.


Analysis: Energy consumption matters, but it’s still huge for gamers

To be clear, power efficiency and power consumption are important features in a laptop, so it makes sense that Intel tries to balance power consumption to preserve battery life. But if you’re gaming, you’re much more likely to leave a laptop plugged in so you don’t get degraded gaming performance.

Intel might have just throttled the GPU entirely, rather than just the battery, because the Samsung Galaxy Book2 Pro laptop isn’t really designed for gaming. Still, gamers aren’t just using gaming laptops, so having a workaround for Intel’s DTT technology is a huge boon for gamers who might be on the road for work but want to relax in a hotel room with some playtime.

Hopefully Intel offers an easier workaround than disabling the feature entirely, or at least offers a software option to unlock GPU performance so users can still use DTT if needed.
