I've just posted my complete review of the Intel Pentium III (aka Tualatin) 1,13GHz processor and Intel D815EEA2 stepping B motherboard. To learn how the 'Tualatin' performs be sure to read the whole review, and check the benchmarks. Below is a snippet from the review:

Intel has recently unleashed the fastest Pentium III processor to date, clocked at 1.13GHz. This new baby from the Santa-Clara giant is known under the sweet code name of Tualatin. This new processor is supposed to be the last incarnation of the Pentium III family before it disappears from the Intel's catalogue in favour of the Pentium 4. Engraved in 0.13µ the processor doesn’t contain any architecture changes except a new design along with a new frequency. Intel sent us this valuable processor along with a stepping B i815EE based Intel motherboard. The Pentium III 1,13GHz targets users that are on the look for affordable power. It will most likely be available through system integrators since Intel will probably not promote the Tualatin beside its OEM partners. So here goes the review!
