Intel Celeron 266

Technically a dreadful CPU! It's basically a Pentium II (which doesn't sound to bad) but without L2 cache. It has none, nothing. This impacts overall performance of the CPU and above all: it feels slow when running Windows '98. Surprisingly some benchmarks are nearly as fast as a Pentium II 233. I suspect those benchmarks don't need much L2 cache at all.

Luckily Intel decided to get rid of the 'Covington' processor fairly quick. After releasing the 266 and 300MHz models they started shipping the so called 'Mendocino', the same as Covington but with 128KB full-speed on-die L2 cache. Technically speaking Intel used their best L2 'method' for their budget CPU because the Pentium II only has off-die L2 cache at just half the clock frequency of the CPU. However, the L2 cache of the Pentium II was bigger with 512KB in total which seems to get things straight again.

Despite that this CPU is 'dreadful' (regarding performance) I think it has a certain flair to it. It's the first Celeron and first time that Intel ran two lines for the desktop market (Celeron as budget, Pentium II for high-end). In 1998 I was fond of the first Mendocino CPU's but looking back nowadays I kind of like the Covington.

Running two lines (high-end and low-end) had another big advantage for Intel in 1998: Pentium II's predecessor, the Pentium MMX, used socket 7 systems which also hosted CPU's from other manufacturers (i.e. AMD and Cyrix). To increase adoption of the Slot 1 motherboards (which was only used by Intel) and to decrease the use of motherboards that could also be used by other manufacturers, Intel decided to use a budget CPU on Slot 1.
