Intel (Xe) DG1 spotted with 96 Execution Units (Entry-level GPU)

I wonder if they're holding the DG2 (assuming it's a more powerful GPU because why would they make one with a similar number of compute units as an iGPU) back from the public so early impressions aren't bad. Since the drivers are way newer than AMD's and nVidia's, I'd imagine that there's a ton of performance to be gained with more driver development. How a bigger GPU performs against the midranges of AMD and nVidia is really important so bad (or even just middling) publicity before it launches would hurt sales. That said, I don't expect much from the first generation (or even second) of dGPU's from Intel since the competition have both been in the market so long.
Does anyone have any insight on how this will affect game devs? Do they now have 50% more work in this department because of a 3rd GPU manufacturer? I'm not sure how much work is done on the game devs' part in terms of optimizing for different architectures. I figure it's partly API dependent?

Intel hasn't reveal the specs yet.
DG1 is powered only from the PCIe slot so that is 75W maximum power draw. Probably is a lot lower than that limit.

The full context, as pointed out in the video by both Steve and Gordon, is that this hardware is basically for developers to get used to it before anything goes out to the public. The performance is expected to be somewhat better on release (which will be months and months down the line). 96 execution units is what's supposed to be integrated onto the high end Tiger Lake chips, but this version has it's own non-shared memory. This is really a look at their lowest-of-the-low discrete stuff.
No. But if the Alienware UFO ever does come to market in the next 12 months, it will probably be using Tiger Lake U chips, which could have performance not too far behind this, since that's also 96 EU (but with shared memory instead of dedicated).
Very much depends on how different the drivers are compared to their iGPUs. Afaik, Intel are the biggest GPU manufacturer out there (if you count iGPUs, which you should), so many devs should already have experience with Intel GPUs.
I wouldn't be worried about the performance competitiveness yet. Give them a few more years. For context, when we were developing support for DXR for BFV, we were often running and testing with 10-20 fps on a prototype hardware, but nVidia did a great job and in the end we ended up with 50+ fps on the actual shipping hardware.
