MLID is worthless as a source of info. He claimed high end Battlemage and even Battlemage as a whole was cancelled for months, I don't believe desktop Celestial has been cancelled for even a second of he's the source
Least anyone forget that "AI" and Intel's lack of having a product that might compete with AMD or Nvidia was behind their jumping into the GPU waters in the first place (having a desktop GPU that could be used for Gaming OR having usable iGPU's was merely a nice side effect of dumping tons of investment into making GPU's).
If we were to take Intel's track record into account, where they have in the past invested nearly countless loads into markets before abandoning them shortly afterwards, one might question if the drivers for ANY of the existing Intel GPU products will ever get any better or will be abandoned much like their GPU offerings might be.
Frankly IDK if Intel has completely given up on "AI Accelerators" or not.
