CPU Exemplars With This Coordinate
ARCHITECTURAL_ESTIMATE
Intel 4004
1971 - intel
A 4-bit microprocessor showing the CPU as a new integrated control object: narrow datapath, small state, external memory, and board-level system role.
ARCHITECTURAL_ESTIMATEARM7TDMI
1994 - arm
A compact RISC core where clean ISA structure, scalar pipeline, and low-power embedded use define the technology more than peak throughput.
VALIDATED_LIMITEDIntel i80486
1989 - intel
A mainstream x86 CPU where compatibility, pipelining, on-chip cache, and integrated floating point converge into the modern desktop processor shape.
ARCHITECTURAL_ESTIMATEMIPS R4000
1991 - mips
A 64-bit RISC workstation/server CPU that makes clean load-store design, deep pipelining, and cache hierarchy visible as technology choices.
