I suggest watching this video about Intel Graphics, and adding the comments about the culture which is inside Intel, and thinking about the 10 nm fiasco, and the reason behind it.
Sometimes AdoredTV has good insight. And sometimes they take info and then drive off into the swamp like Charlie does at Semiaccurate. Charlie's "agenda" typically has to do with Nvidia or Intel is screwing up and warps it into a doom and gloom story. AdoredTV heavy bias is for 'enthusiast GPU consumers and community". If there is a that aspect then he tends to drive off into the swap with the company emphahsis isn't firmly directed in that direction.
The driving off into swamp is fairly evident in this one for the 3 minutes spends on "failure of Intel graphics" that is really about Intels CPU marketing campaign that was hooked to core counts. The i3 - i7 etc benchmark charts.... .really nothing to do with Intel graphics at all. It was Intel marketing money poured into enthusiast marketing campaigns, but actual graphics? Nope.
Other parts are bit warped also, but more clear when viewed through "only the enthusiast GPUs matters" lens. He comments how Tiger Lake iGPU looks OK but the DG1 is a disaster. Well they are probably both primarily the same Xe-LP implementation. There are three different implementations that Intel is pursuing.
Intel has covered this (and so did AdoreTV in a previous video but seems to have have not weaved in this one. )

Those overlap in performance, but have different 'efficiency' in the overlapping range:
The Xe-LP pushed up into the lower bounds of the Xe-HP targeted zone would not be a impressive GPU ... just like DG1 is. The DG1 is a lower-end entry ("desktop") with the baseline of the new common GPU architecture direction. The Xe implementations are a uniform chip implementations over the whole span though. The Nvidia MX250 mobile GPU isn't a 'failure' because it doesn't have all of the Tesla V-100 features in it. Which leads to the next "doom" in the video the "Ponte Vecchio" multiple chip solutions. Those are meant to compete in the space the V-100 is in. ( high end HPC. AI-ML workloads , etc.). In other words not in the enthusiast space either.
DG2, as described by the rumors so far, again probably first real competitive entry-mid level desktop price zone solution. So Nvidia 2070 like performance at entry level prices in 2021-2 on a, at that point, more bulk, affordable TMSC ("tailing edge" ) process makes sense. By that time most of TSMC's current 7nm customers would have moved off to 7-Plus nm , 6nm , 5nm or something else. There have been several indications that Intel is going to move to push chip dies with lower profit margins off onto external fabs. That is one reason they were resigned to chucking the mobile cellular modem business. Right now a substantive percentage of Intel's fab capacity is dedicated to churning out low margin modems for Apple and not for higher margin products. Sub $150-200 GPU cars in 2021-3, no way Intel wants to through their high end fab capacity at that.
Throw their 7nm at very high end HPC cards for expensive data center systems and supercomputers. Probably so. [ I wouldn't be looking for Xe-HPC so show up on TSMC 7nm at all. Xe-HP sitting in the "inbetween zone" could be a good case for something on some non-Intel process. Perhaps starting with TSMC 7nm and then moving on from there as move more 'enthusiats' range that doesn't match most of what Intel is doing at higher end fab processes. ]
Similarly DG1 spun also in the laptop space as useful. AdoredTV recently ran with a rumor that Rocket Lake comes with Gen12 10nm GPU coupled to the 14nm CPU core in the same package. Hmmm, if DG1 is Xe-LP and it is coupled to the a GPU-less CPU die ....... Intel would be pitching DG1 variants in the laptop at the same time selling an iGPU solution.
intel insiders who wanted Intel to jump into the middle 'enthusiasts' GPU space probably would be grumbling to AdoredTV. And the Marketing folks dragged over from AMD who chased Nvidia in that space probably would doing "great white whale" chasing with Intel's bigger pocket book.
Raja Koduri's ego may be pushing in all four directions at once. Xe-LP , both variants Xe-HP is suppose to cover , and Xe-HPC all at once. That would probably not end well for Intel. It doesn't look like they are. Intel is doing XP-LP first. ( since that is closed to the dominant GPU area they have the most control over) and are probably Xe-HPC next ( since that would be a new area with much better profitability). The 'enthusiast' part is probably the one they'll do last. However, they probably will stake out that zone with "marketing" hype which will be easy to dismiss as a "disaster" and "bunch of clowns".
If Intel's 7nm is tuned for better coverage of laptop power then Xe-LP would probably do quite well. Xe-HPC probably will need lots of large dies to push through extra large core counts at non extra high clock speeds. For embarrassingly parallel HPC workloads that is probably a pretty good match if the software stack matches up. It looks like Intel is trying to harmonize the various more specific AI-ML solutions they have also bough with this
To loop this all back to somewhat of a relevant Mac Pro context AdoredTV labels Vega as one of the top 3 tech disasters of the last decade. And yet thousands of folks get their profession work done on Mac Pro, iMac Pro , iMac, and MBP that use it. As an ultimate high end gaming card he has some points. As a computational get work down card; not so much. He has been throwing some 'hate' at Navi too and yet the W5700X will probably work out just fine in the Mac Pro user base.
