Without even counting on the TSMC 6nm full node advantage. That's even worst than what I expected

Full node? N6 is "7nm class" just like every other "7nm" process
Which makes it a full node ahead of the 10nm class 8lpp that ampere is fabbed on.
I was comparing to Ampere, which is what intel is referring to in their official competitive slide deck
Which makes the performance a little more embarrassing when you also consider that RTX 3060 mobile it's being compared against is only full-fat GA106, with 13.25 billion transistors and a 276mm2 on the much less dense Samsung process.
A770m is 21.7 billion transistors and 406mm2 on TSMC N6 (!!!)
47% bigger die, 64% more transistors used compared to GA106 on a process that's almost certainly more expensive per transistor, to say nothing of more expensive per die area. Yikes.
While we're picking on poor A770m, should also be noted that RTX 3060 mobile gets by with a 192-bit memory bus so only 3/4 the GDDR6 BOM cost and some board area saved there too versus the 256-bit one for A770m.
No wonder Intel's not in too much of a hurry to get these out the door en masse.

So all of the passed around Intel GPU numbers for 3D Mark are useless, Intel drivers have something called "Advanced Performance Optimizations" that added specific illegal optimizations for 3D Mark Time Spy and Port Royal, which are against the rules, and of course are considered a "cheat". Which explains why these GPUs did well in synthetic tests, but not actual games.
Intel released a new driver today that gives the user the ability to disable such optimizations, with reduced performance of course.

No, the only reason is the aspect ratio of my monitor is 16:10.
Try running something like 1280x800 or even lower to give the cards a chance
Why would lower resolutions help slower cards catch up? Higher resolution may actually help improve BVH cache hit rates and increase coherence in ray packets benefiting architectures that don’t handle divergence well.

Don't we see the gap between AMD and NVidia widen with increased resolution?
Who said it would help slower cards catch up? None of the cards is comfortable at that resolution based on performance, it doesn't mean the gaps would be smaller, bigger or even same at resolutions they're comfortable with. Whichever it is depends on several factors, obviously.
It’s a synthetic benchmark so comfortable frame rates aren’t very relevant. I was referring to your earlier comment that “the differences might be quite a bit different”.
In RT specifically? Not sure as there isn’t a lot of data on pure RT benchmarks at different resolutions.

I disagree, we have a whole thread dedicated to showing the contrary...
Examples? Mostly rasterized games with a sprinkling of RT don’t tell us much.
