tough luck, could have been great mining GPUs

Direct performance comparisons should not be made with the igpu versions as these don’t have dedicated VRAM neither do they have the same VRAM size or speed. The 1660 super and the 1660 had the exact same specs except from VRAM speed (GDDR5 vs GDDR6). The super version was 15-20% faster. And the GT 1030 GDDR5 vs DDR4 had 100-120% difference. Factor in drivers, optimizations, etc, and we really are in the dark about how well these perform.

In any case here is a fun exercise. Compared to Tigerlake we have:
(i) 5.33x the EUs (512 vs 96)
(ii) likely 1.33x higher frequency (1800MHz vs 1350MHz)
(iii) likely 2.1x higher “IPC” due to the various VRAM differences.
So, in total we have something around 15x faster than the iGPU on Tigerlake.

Now the 3090 is ~20x faster than the Iris Plus G7. It follows that the 3090 is 33.3% faster than DG2. The 3090 is also ~1.5x faster than the 3070. Hence, DG2 is 12.5% faster than the 3070.

I would say that at worst I expect DG2 to perform about the same as an RTX 3070/RTX 2080Ti and at best as a 3070Ti. Not bad but it needs to come out this year. In Autumn 2022 we expect to have the 4000 series and significant performance improvements, so this tier of performance will probably be relegated to the xx60-xx60Ti tier for $330-$400 MSRP. In any case with the current situation of gpus pricing and availability due to mining, scalping and chip shortage, MSRP goes out of the window anyway and any gpu available at a sane price is a winner.

I wonder if Intel would release DG2 cards into the consumer market. Launching a new line of products costs a lot of money. And no guarantee of success. Selling the hardware to one of the streaming services (Stadia or Luna) would be the safer option. That's a controlled environment. Game compatibility is less of an issue.

The iGPU is based on DG1 while the high performing discreet are based on DG2. Are the two comparable? At the very least, DG2 is supposed to support hardware ray tracing while the DG1 based GPU's don't. One would think there is more that differentiate the two to necessitate different codenames.
