The binning process where higher end CPUs are marketed as lower end parts has been going on forever. Only the first generation Celerons (which everyone hated) had no L2 cache. The second generation had 128KB of full-speed on-chip cache, which is actually why it overclocked well. The Pentium II and early Pentium III had 512KB of half-speed off-chip cache which struggled to keep up with the CPU when overclocking.
