How fast is a mega flop?

Sounds like a question for John Kerry

mega fast.

It's a million floating point operations per second.

 

[shiner]

A mega-flop equals one million floating-point operations per second, which is a basic measurement unit of performance of computers used for numerical work. One giga-flop equals 1,000 mega-flops and one tera-flop equals 1,000 mega-flops

Google is your friend.

Yeah, but that is a precise answer defined in unit that I can't comprehend. I was hoping someone could give a relative definition in terms of ghz, a unit I am familiar with.

Faster than I can throw you.

 

[Kilgor]

A million flops per sec.

It's not relative to GHz.

You can't really do that because you're comparing apples to oranges. Hertz refers to the clock speed of a processor. On each clock, the processor can do one operation. Most instructions take more than one operation though. If each floating point instruction takes only one clock cycle, then flops and hertz are the same. You'd have to know something about the processor architecture to say how many flops it was capable of.

Yeah, I totally understand what you are saying. But, don't we basically know how many flops an AMD and Pentium chip are capable of?
Doesn't a P4 2ghz run at about 1.5 megaflops?
