Figures

Intel Pentium II: recorded figures

provisional A figure marked provisional is recorded but not accepted: its evidence is unsettled. It may rely on one source, an unconfirmed announcement, or a digit read from a damaged scan. The reason appears under the figure. The catalog shows the figure but never uses it in a multiplier. How records are judged.

Metric Value Evidence Basis Method Source
Clock frequency cpu provisional 300 MHz Confirmed Vendor-rated Nominal clock Stated by the vendor This figure remains provisional until the cited source is corroborated for the exact configuration.
Dhrystone MIPS per MHz cpu provisional 2.2 DMIPS/MHz Reported Measured Benchmark run Published independently dhrystone 2.1 A named historic Dhrystone 2.1 result, normalized by the run clock; the one-source result remains provisional.
Thermal design power cpu 43.0 W Confirmed Vendor-rated Rated power Stated by the vendor Max Processor Power at 300 MHz with 512 kB of L2 cache, CPU ID 63x, at nominal core and 3.3 V L2 supply voltages. Intel's Max Processor Power, which the datasheet defines as 100% of the core and 100% of the L2 cache. It is not the Max Thermal Plate Power of 41.4 W printed beside it, and it is specific to CPU ID 63x: the same table rates a 266 MHz part at either 38.2 W or 19.5 W depending on stepping, and the faster 333 MHz part at 23.7 W, so this figure belongs to the 0.35-micron silicon and cannot stand for every processor sold as a Pentium II 300.

Metric Value Evidence Basis Method Source
Clock frequency cpu provisional not applicable The Pentium II predates dynamic turbo modes. Not stated Vendor-rated Peak clock Stated by the vendor This figure remains provisional until the cited source is corroborated for the exact configuration.
Peak FP32 rate cpu provisional unknown The processor has floating-point hardware, but the cited specification does not publish an FP32 peak in FLOP/s. Not stated Vendor-rated Theoretical peak Stated by the vendor This figure remains provisional until the cited source is corroborated for the exact configuration.
