About this machine

Apple's specification for the 3GS names the chip and lists what the phone was sold in, and gives no clock, no installed memory and no power rating. Apple has never published those for any iPhone; the figures this catalog holds for the first-generation phone came from a teardown.

Figures for the whole machine

Apple iPhone 3GS: system 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 600 MHz Reported Measured Nominal clock Stated by the vendor AnandTech reports 600 MHz for the 3GS Cortex A8. Apple does not publish a clock, so one independent source leaves the figure reported.
Storage capacity storage 8 GB Confirmed Vendor-rated Design capacity Stated by the vendor One of the flash capacities Apple lists for this phone. Storage, not memory. Apple states flash capacity decimally, the way makers of flash and disk do, and this catalog reads it that way.
5 documented absences

Metric Value Evidence Basis Method Source
Clock frequency gpu unknown Apple gives no GPU operating frequency in the cited technical specification. Not stated Vendor-rated Nominal clock Stated by the vendor Apple gives no GPU operating frequency in the cited technical specification.
Peak FP32 rate gpu unknown Apple publishes no standalone FP32 throughput figure for this phone GPU. Not stated Vendor-rated Theoretical peak Stated by the vendor Apple publishes no standalone FP32 throughput figure for this phone GPU.
Memory capacity whole-system unknown Apple does not publish installed DRAM capacity; listed flash storage is not working memory. Not stated Vendor-rated Design capacity Stated by the vendor Apple does not publish installed DRAM capacity; listed flash storage is not working memory.
Memory bandwidth whole-system unknown Apple publishes neither a memory-interface width nor a memory transfer rate for this phone. Not stated Vendor-rated Theoretical peak Stated by the vendor Apple publishes neither a memory-interface width nor a memory transfer rate for this phone.
Rated power consumption whole-system unknown Battery-life durations and charging limits are not a whole-system power rating. Not stated Vendor-rated Rated power Stated by the vendor Battery-life durations and charging limits are not a whole-system power rating.

Editorial notes

Flash capacity and charger ratings are recorded as the quantities they are, and never stand in for working memory or whole-system power.
