If a CP programme (program for americans) requires an Intel Pentium 4: 3Ghz, does an Intel Duo 2Ghz = 2x 2Ghz?

Question

i.e. when it's a dual processor does one double the listed Ghz so that a Intel® Core™ 2 Duo E6400 processor (2.13GHz, 1066MHz, 2MB cache) is in fact worthy of being considered a 4.26Ghz processor?

Answer 1

Core 2 Duo will run faster than the 3 ghz machine EVEN on single threaded applications. It is a completly new processor and even though the clock speeds seem lower than the older Pentium 4 speeds, the new processors do more whilst using lower frequencies.

This is similar to how some cars can go 60 mile per hour and achieve 45 miles per gallon whilst other will go 60 miles per hour and achieve 12 miles per gallon (Hummer).

So Intel primarily made the new processors more efficient, and they can do more work per clock cycle (Ghz) than the old Pentium 4's.

So in short, your program will run faster.

Answer 2

Most applications and games that are out right now don't fully utilize the dual core CPUs. As a result, you're running at 2 Ghz. The best way to optimize your computer is to CTRL+ALT+DEL to bring up the task manager. Once there you can right click different processes and set the affinity to one core or the other. that way you can divide up the work it's doing.

The slowest core 2 duo is faster than the fastest pentium 4 regardless of clock speed. They use a different architecture with a higher instruction set and more on die cache. Basically Intel learned from AMD that high clockspeeds aren't as important as good architecture.

Answer 3

it really depends, but i dont know if a 2 ghz would do it.. but what i can tell you is despite the advertised ghz, the clock speed is different.. and a single core p4 3.0 is about equivilant to a amd 2.6 or so, and the new intel chips are clocked alot higher than the amd am2's.. in some cases up to 30% faster.. so you might be able to pull it off, but id search online.. just google search the compatibility with your program, or look for forums and post the question.. hopefully somebody can tell you for sure.. good luck!

Answer 4

It depends on the application. If it was written to use multiple "threads", so both cpus are in use, it might be enough. 2 x 2GHz never gives you 4GHz equivalent. The two CPUs have to fight over resources like memory. Best to check with the software supplier.
