People have always valued performance and power consumption, regardless of brand. AMD used to have it all back in the day. Having said that, I don't remember many people complaining about their Intel rigs consuming more watts for worse performance, compared with AMD.
Of course you don't remember. Nobody was buying Intel rigs back then, aside from the people who were buying desktop Pentium M boards, and so obviously wouldn't have complained about its performance-per-watt.
The DDR based P4 systems were universally dogs, only the Northwood P4 with RAMBUS was competitive in certain specific benchmarks such as Q3A and linux kernel compilation.
You're conflating a bunch of different things. The first P4 incarnation, Willamette came with either RDRAM (very expensive, but a lot faster) or PC-133 SDRAM (cheap and widely available), and was decent but not great with the former, and complete crap with the latter. By the time Northwood came around, Intel had a DDR chipset; RDRAM was faster still, but DDR was still plenty competitive, and Intel really raced ahead in this period because AMD initially floundered on their 130nm process. Then, Intel finally left RDRAM behind for good in early 2003 with Northwood-C and the 875P chipset, which just completely crushed any remaining competition from the K7 line.
