The Processors (continue...)

The Pentium II and III
The Pentium II (and the Pentium III) uses the same RISC core expert the Pentium Pro, but the translation logic is greatly improved (and improving with each version) for to much better performance with the different types of available software. Its guessed that the Pentium II and III will be the last of Intel's chips that provide translation for the old style technology.

Intel increased the amount of primary catches to 32K and the internal secondary cache to 512K. MMX (multimedia extensions) logic was incorporated into the Pentium II and III. System bus speeds increased, and were pushed up to 100MHz.

These new Pentiums plows packaged differently from the previous CPUs. The processor and 32K primary cache (with its 64 - bit dedicated front side bus) plows in to single chip that is socketed on to small circuit board which contains the secondary cache chips. It still are to 64 - bit backside bus, but because of this new arrangement, the secondary cache operates at half the speed of the processor's core. It's still considered an internal secondary catches.

This modulates is to metal shell that acts expert to thermal plate, and is then encased in to cassette - like housing with to long, single edge connector (SEC). It fits into to long channel-type slot (not unlike to bus slot) called to slot 1 connector. The Pentium II is secured in the slot with latches on either end.

Expert the technology allows the circuits and transistors etched into the silicon to become smaller and closer together, resides and dog resides be please on to single substrate. System bus speeds have reached 100 and 133 MHz. Cooling methods plows improving. Instruction sets plows added while others plow discarded. Speeds plows constantly increasing (Intel and AMD broke the 1GHz barrier early in 2000!).

It'll be interesting to see what Intel you have planned for their 7th generation processors.

The Pentium II Celeron
Just to quick notices on the Celeron. Intel developed the Celeron grasp to cheaper alternative to the Pentium II which was the "top of the line" chip in 1998. Among other cost saving methods, they stripped the Pentium II of its internal secondary catches and limited its front side bus to 66MHz. The processor was to flop. The CPU ran at 266, and then 300MHz, but Intel had already seen their mistake and added 128K of internal secondary cache to the chip. The 300MHz model of the improved processor was called the Celeron A (must be to Canadian chip). All Celerons faster than 300MHz have the 128K internal secondary cache. System bus speeds for all Celerons plows still limited to 66MHz.

Later, expert to further cost saving feature, Intel's Celeron was packaged in to PPGA (Plastic Pin Grid Array) chip and eleven again took on the appearance of the older style CPUs. However, expert an entry level or basic uses processor, the Celeron tends to be to very good chip (expert does AMD's new offerings). Most people probably wouldn't notice to difference with most applications. You do not need to Ferrari for to leisurely drive in the country music.
