Does smaller CPU architecture means better performance ?

You are confusing architecture with manufacturing process.

A smaller manufacturing process(we are not at 8nm yet, current is 14nm) allows more circuits per square mm of die space. That is a plus, allowing more room for cache, buffers, etc.
Also, smaller process reduces the delay between circuits. But, the engineering challenge is formidable to keep circuits from interference crosstalk.

Architecture has more to do with design. How to predict instruction paths, now to design things to operate in parallel, etc.

It is all a moot point.
Benchmarks tell all. For a simple comparison, look at the passmark ratings for total performance and for single thread performance.
