4 million of what? If its 3.75 million of the small GPU that they've already been shipping, getting stuffed in low end laptops so it can claim to have a dGPU, then who cares, that's not going to change anything.
No Alchemist chips have formally been announced (although they've said that the bottom tier A370M will be announced on March 30th), they aren't shipping yet, and we have no hard data yet on how well they compare to the competition.
If these chips get used instead of 3050 chips in laptops, then that frees up those 3050 chips for use in desktop GPU's or more laptops can get better graphics.
And you have no idea how many chips better than that will be shipped.
They're gonna ditch GPUs again and make whatever the HPC markets that are their bread and butter, and go back to making small iGPU esque stuff for the OEMs.
Perhaps, but on the other hand, there seems to be a plan for them to find a competitive advantage with multi-die chips that do something similar to SLI, but then with multiple dies on a chip each rendering part of the image. Although that doesn't seem to be part of the upcoming chip.
Google, Amazon, Tesla, etc are designing their own hardware.
Yes, but the CPU's in those system are off the shelf chips. None of those companies have the means to design large chips. Facebook does use modified mobile chip in the Quest 2, but that is a chip designed by Qualcomm for VR/AR systems in general, not a chip tailored specifically to the needs of the Quest 2. For example, the XR2 that Facebook uses in the Quest 2 has 5G support, but that's not actually used, so it's just wasted die space.
Intel's plan is for those companies to be able to order a chip from Intel that has the features they want.
Intel always spends huge money. They spent billions putting LEDs in clothes.
Did they really? I'm assuming that you are referring to Intel Edison, which actually was an IoT platform, which also focused on wearable computing. LEDs in clothes was just a demo.
They put a Intel Atom on a little motherboard, which certainly doesn't cost billions to do, so I'm not sure where you are getting that from.
