You can't BS Physics although you are doing your best to try. Nehalem takes 4 cycles for its L1 as opposed to 3 for Penryn. It takes 39 cycles as opposed to 15 for cache above 256KB. These are indisputable facts and can't be handwaved away no matter how hard you flap your arms. The same cache structure that you criticised in Barcelona Intel had to adopt for Nehalem if they wanted a multi-core multi-processor architecture that would scale. It's just not ideal for single-thread is the only drawback, Penryn is.
