x86 MICROPROCESSORS
KEY POINTS OF THIS CHAPTER
l The Pentium Pro was the sixth generation x86 processor and it was a very great
success compared to Pentium.
l Some processors based on P6 microarchitecture had MMX and SSE instructions.
l MMX and SSE are meant for faster DSP operations.
l MMX does not add new registers but SSE adds a new set of registers.
l The Netburst microarchitecture followed P6.
l Many processors were released with Netburst, but because of heating issues, it turned
out to be an unsuccessful microarchitecture.
l The Core i7, i5, d i3 processes names started with the Nehalem microarchitecture.
l Sandy Bridge and IvyBridge ...
