Intel Low Voltage Pentium III 800 - RJ80530KZ800512

RJ80530KZ800512 is a low voltage Pentium III-S microprocessor in FC-BGA package. This processor is packaged the same way as mobile Pentium III-M processors, but it's not a mobile CPU. For once, this CPU doesn't include Deep Sleep and Deeper Sleep low-power states that are included in mobile processors. This CPU doesn't have SpeedStep technology either. The RJ80530KZ800512 and two other low voltage desktop CPUs (933 MHz and 1 GHz) can work in dual-processor systems, while mobile processors cannot.

Intel Pentium III 1000 - RK80530PZ001256 (BX80530C1000256)

1000 MHz
256 KB L2 cache
370-pin FC-PGA2

Intel Pentium III-S 1133 - RK80530KZ006512 / RK80530KZ00651E (BX80530C1133512)

There were two variations of Pentium III Tualatin microprocessors. Desktop version of Pentium III Tualatin CPUs had 256 KB L2 cache. Server-class processors had 512 KB L2 cache and were branded as "Pentium III-S". You can see on the picture that the processor is marked as Pentium III-S. The difference between desktop and server Tualatin microprocessors was not only in L2 cache size. Desktop processors didn't support dual-processing, and only Pentium III-S CPUs could work in dual-processor systems.
