Today had a little playing around with the Pentiums. I started with the 90MHz SX909, which is the version that has the famous FDIV bug, and ran up through 100,133,150,200, and finally 233 Mhz. It is quite a production range that can all be used on the same motherboard and chipset.

Playing Doom and Doom2 really highlights the significant speed difference over the 486DX2-66. The combination of the faster local L1 and L2 cache, and the superscalar execution is noticeable.

It is nice that all of these still work fine, and a few of them were overclockable.

Good memories across these as well. I have a great memory buying a Pentium 133 when it was first released.
