Intel had a massive R&D budget and 110,000 employees circa 2020. (Vs 12k and 14k for AMD and NVIDIA, both of which have higher market caps than Intel now).

It wasn't a money problem, it was a badly run company on all fronts. When it comes to R&D the sheer magnitude of the money they squandered is legendary. They lost billions on Larrabee, billions on mobile chips, helped invent phase change memory and even made drives with it, and then dumped it for nothing, the list goes on. It's bad management all the way down, and impressively so, considering that many of these initiatives were the right products for the right time just with a horrible execution (massively parallel compute/GPUs launched Nvidia to a 4 trillion dollar valuation, mobile chips are a huge industry, etc). Arguably they needed to streamline and downsize well before they did. They were full on old school IBM level bloat.

The last few years before their implosion was indeed MBA style running the company into the ground (they had a particularly awful CEO during that period), but that was just the capstone on a large decline, during which Intel had massive budgets that they squandered.
