Hugh, I always thought Microarchitecture * Clockspeed = CPU speed. I thought the node only matters in terms of power draw and thus heat output. Is this wrong?
Hmm, let’s see. Your microarchitecture and clock speed do dictate your processor performance. But, equally important is your process node. If it’s built on an inefficient node, it will take more power and produce more heat to provide the same and sometimes even worse performance as other chips built on a more efficient node.
This became so much clear when qualcomm released the snapdragon 8 gen 1 and the snapdragon 8 +gen 1. The 1st was built on a samsung node and performed poorly compared to its predecessors. The 8+gen 1 was built on an improved TSMC process, which actually improved performance and provided better battery life.
Then, there are times that your SoC implementation is poor. Like for example, the infamous snapdragon 810 (and 808). That was a dumpster fire full of throttling issues.
