Looks like Intel's ARC GPUs are more powerful than the first tests have let on.

The culprit is Intel's DTT technology, which is meant to save battery life. However, it basically underclocks the GPU and CPU to achieve this, as well as lowering GPU usage, resulting in much lost performance. In a test with and without DTT, the result was about twice as much performance without DTT; while originally the 350M had only about 30% more performance than the MX 450, but with DTT disabled it handily beat the 1650.

The stuttering is still there, but this should be fixed with driver updates. Now Intel has to finetune DTT to turn off by itself in games and some applications and they could have a great mobile GPU at their hands after they fixed the other driver-related problems.

It's hard to understand how Intel made this oversight. I mean, I could get it if it were 10%, but 50%? How could they miss it?

I would love to see some comparison of the battery life with and without DTT. Maybe deactivating DTT will tank the battery life?

I hope Intel brings some IPC gains with its 13th gen besides the rumored higher clocks (up to 5.8GHz), because if they don't...This also tells us that Zen4 will be a fair bit faster than the 5800X3D, otherwise AMD wouldn't have launched it.

The much enhanced cache should do the trick for Intel in a similar way as it enhances the performance of the 5800X3D. Even if there are no other changes (apart from the number of e-cores), that would already be a nice uptick. I just wonder if Raptor Lake will consume more or less power than a Threadripper...
