How many operations per second can perform by a modern fast mainframe digital computer.
1,00,00,00,000 operations per second can perform by a modern fast mainframe digital computer.
Under ideal circumstances, a high-end desktop x86 processor can execute over 100 billion instructions per second. In real world usage scenarios, however, the CPU is often stuck waiting for other components to answer back, mostly RAM and disk.
Clock Speeds are usually determined in MHz, 1 MHz representing 1 million cycles per second, or in GHz, 1 GHz representing 1 thousand million cycles per second. The higher the CPU speed, the better a computer will perform, in a general sense.
