Question

Intel® Core™ i5-7500 is one of Intel's 7th generation of microprocessors and was launched earlier in 2017 and has been used in many computers, including Dell OptiPlex 7050 Tower.
a) How many CPU does this microprocessor have? What's its cache memory capacity?
b) According to Intel, this microprocessor's max clock speed can reach 3.8 GHz. If an instruction requires 5 clock cycles to complete execution in this microprocessor, then, in terms of nanoseconds, how long does it take to get executed? Round the number of your answer to the nearest thousandth

Answer 1

Answer:

A. 4 CPUs and 6 megabyte cache memory

B. 1.3157 x10^-9 nanoseconds

Explanation:

The Intel core i5 7500 is a seventh generation central processing unit with a 4 CPU core and a 6 megabyte cache memory. It executes task at a clock cycle of 5 clock cycle at a speed of 3.8 GHz.

The relationship between frequency and clock cycle is,

Clock cycle = 1 / ( frequent).

So, One clock cycle = 1 / 3.8 GHz

= 0.3 x10^-9

For five clock cycles = 5 x 0.3 x10^-9

= 1.3157 x10^-9 nanoseconds.
