Front view of Intel Pentium 987

Reasons to consider the
Intel Pentium 987

Report a correction
Much newer manufacturing process 32 nm vs 130 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
More advanced architecture x86-64 vs x86 A 64-bit architecture allows more RAM to be installed and accessed by the processor
Higher clock speed 1.5 GHz vs 0.9 GHz More than 65% higher clock speed
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Supports dynamic frequency scaling Yes vs No Somewhat common; Allows for maximum performance when needed, while conserving power and minimizing heat production when not needed
More l2 cache 1 MB vs 0.5 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
More cores 2 vs 1 Twice as many cores; run more applications at once
