Let's start our lesson with the Pentium Pro microprocessor. Can anyone tell me what generation it belongs to?
It's a sixth-generation microprocessor, right?
Correct! The Pentium Pro was designed to replace the earlier Pentium series and was notable for its dual- and quad-processor configurations. One key feature was a performance increase of about 50% compared to its predecessors at the same clock speed.
What other features make it stand out?
It incorporated superpipelining, an integrated L2 cache, and out-of-order completion of instructions. Remember the mnemonic 'SLOP' for superpipelining, Level 2 cache, Out-of-order execution, and Performance increase!
That's helpful! So, it's all about better efficiency?
Exactly! Summarizing, the Pentium Pro emphasized performance, expandability, and efficiency in processing.

Next, let's dive into the Pentium II. Can anyone tell me what year it was introduced?
I think it was released in 1997.
That's right! The Pentium II was built on a modified P6 core and improved the 16-bit performance. There was the addition of the MMX instruction set as well.
How about the manufacturing process?
Great question! It used Intelβs 0.25-micron technology. Think of 'M2' β for MMX and micron technology. This reduced power consumption while increasing performance.
What sort of architectures did it maintain?
It utilized MMX bus architecture to enhance bandwidth. Letβs summarize that the Pentium II achieved efficiency through improved technology and processing capabilities.
Pentium III and IV Differences
