Dave at ComputerNerd was kind enough to run some benchmarks to help shed some light on the situation. He grabbed a Coppermine Pentium III and a new Celeron off the shelf, slapped 'em each into an Epox KP6-BS board (one at a time, though it is dual-slot board). Then he set the bus speeds as follows:
So what we're getting here is a test of these two CPUs running at almost the exact same clock frequencyat very different bus speeds. I'm not sure these numbers will prove conclusively whether or not the Celeron II is crippled in some way beyond what me know about it (the smaller L2 cache size and lower default bus speed). Ideally, I'd like to see a Celeron 566 pitted against a Pentium III 850E, with the two CPUs running at the same bus speed, in order to determine whether the Celeron is somehow throttled. However, I do think these tests shed some light on the situation.
With that said, let's look at the benchmark results, which I threw into graphs for easy reading:
As I read these numbers, the Celeron II doesn't look like it's been crippled beyond its slower L2 cache andespeciallyits crazy low bus speed. But I'm sure some of you may read the numbers differently. (Heck, Dave did.)
