CPU AMD K5/133 Socket 7
The K5 is AMD's first x86 processor developed entirely in-house. It was introduced in March 1996 and its main competitor was Intel's Pentium microprocessor. The K5 had an ambitious design, closer to a Pentium Pro than a Pentium in terms of technical solutions and internal architecture. However, the final product was closer to the Pentium in terms of performance, although faster from time to time compared to the Pentium.
1996
Technical Specifications
Nominal Frequency (Real Clock): 100 MHz
Performance Rating (PR): PR133. AMD used the "P-Rating" to indicate that the processor performed equivalently or better than an Intel Pentium at 133 MHz, even though it ran at 100 MHz.
Bus Speed (Bus Speed / FSB): 66 MHz (with a multiplier of 1.5x).
Operating Voltage (Voltage): 3.52V (Single Voltage).
Power Consumption (TDP): Approximately 14 Watts.
Internal Architecture (RISC86): Very advanced for its time (closer to the philosophy of the Pentium Pro), as it converted x86 instructions into RISC-type micro-instructions.
Cache Memory: 16 KB Instruction Cache (twice that of the Pentium) and 8 KB Data Cache.
