He's not talking about that.
Intel's problem is they are fat and inefficient.
On the product design side, they have far more employees than their competitors, and they still produce a lower quality product. When you translate that to finances, it means their gross margin is low (lots of employees means high cost).
On the foundry/fab side: Same story. The amount of revenue the fab generates per foundry employee is tiny compared to TSMC - and it's not because Taiwan is cheaper.
Intel was behind TSMC. When Pat became CEO, he set his vision of "5 nodes in 4 years" to get ahead of TSMC. Next year will be the 4th year, and so far that plan is panning out. But doing 5 nodes in 4 years is unprecedented, and the only way they achieved it so quickly is by throwing all kinds of resources at it (e.g. lower than acceptable yields, with Intel eating up the costs of the low yields). This is what he means by "accelerated investment".
So what he is saying in the quote above is: Now that we are near the end of the 4 year period, we need to focus on improving the efficiency of the fab to be competitive with TSMC's prices.
