Sharky Extreme has posted a review on the new Pentium III 1Ghz. Here a blurb:
The Pentium III 1GHz is manufactured using Intel´s .18 micron six metal layer process. It uses a fluorine-doped SiO2 (SiOF) dielectric for reduced capacitance. Its 106mm^2 die, 4mm^2 larger than the AMD Athlon 1GHz, packs in 28-million transistors. It runs at 1.7V and dissipates 33W of power, which compares to 1.8V and 60W of power for the AMD Athlon 1GHz. This does give Pentium III 1GHz purchasers a bit more breathing room when they´re considering what power supply to buy, but we still recommend you get a 300W power supply either way. The Slot 1 Pentium III 1GHz uses a 133MHz system bus with a 7.5x multiplier and supports Intel´s SSE and MMX instruction setsRead more
