CENTRAL COMPUTER GROUP AN /TYA-5 MEMORY DRUMS Memory drums are used as the digital storage elements and system clock pulse generators in the Central Computer Group and each of the Radar and Identification Data Processors (RIDP). The memory drums used in the TAOC are basically similar to those used in the Service Test Equipment, but reflect major structural changes to improved drum memory reliability. The new drums are sealed units whereas the Service Test drums were relatively open. By sealing the drums, drum surfaces and heads are protected from moisture condensation and dirt, thereby reducing possible malfunctions from these factors. The production Central Computer drum has a capacity of 1,123,200 bits, operates at a speed of 2667 rpm, and generates a clock frequency of 333 kcs. The drum rotor diameter is 15.8 inches and provides 150 tracks of 7488 Other units of frequency are the kHz, equal to 1,000 Hz or 0.001 MHz, and the gigahertz, equal to 1,000,000,000 Hz or 1,000 MHz. The megahertz, abbreviated MHz, is a unit of alternating current (AC) or electromagnetic (EM) wave frequency equal to one million hertz(1,000,000 Hz). 1.4mhz divided by 333kc = 4,2042042 1.4ghz divided by 333kc =4204.2042042 A7 chip set has 2 cores en.wikipedia.org/wiki/Apple_A7 So in other words....It would take the speed of 8408.5 TYA-5 drums to equal the speed of 1 Iphone 5s
