Intel Arc revisited with DTT disabled
BullsLab is a South Korean YouTuber who delivered one of the first benchmarks of Intel Arc Alchemist mobile GPUs. Upon revisiting the tests with updated Arc drivers, he discovered that performance is significantly limited by a technology called Intel Dynamic Tuning Technology.
The Dynamic Tuning Technology It is essentially an alternative to AMD SmartShift and NVIDIA Dynamic Boost technologies, all of which are designed to shift power between CPU and GPU, depending on where it is needed the most. Without a doubt, that should provide a visible performance boost by unlocking more power to crucial components. It is not quite clear how much different this technology is from Deep Link’s Dynamic Power Share, which is advertised by Intel for Arc GPUs.
As it turns out, DTT might have been the reason why Arc A350M mobile GPU, the slowest from the Alchemist series, has performed so underwhelming compared to other solutions. With DTT disabled, Arc A350M sees a massive performance boost and unlocked GPU and CPU power. This immediately unlocks higher clock speeds for both components:

Unfortunately, Arc A-Series are still not available worldwide. Intel did not even bother to send review samples to any media, therefore, we can only learn about those problems over time. Hopefully, the Dynamic Tuning Technology and later Deep Link Technology will do exactly what they were designed for, not the opposite as it is right now.
But availability is not Intel’s only concern right now. The Alchemist GPUs still encounter graphics glitches and stutter in some games. Those will surely take time to fix. The last Arc driver featured 7 game and 2 software related fixes, but the list of known issues is still long.
