Which CPU is faster, an Intel dual core 3.4 MHz or an Intel Core Duo 1.8 MHz?

Question

These two chips are the same price. However, I have a motherboard I want to use that only accepts no higher than dual core, not the new Core 2 Duo. Is it worth it to buy a new motherboard, or just use the mobo I have, and buy the Intel Pentium D 945 3.4GHz LGA775 CPU? (I have no CPU for this motherboard yet)

Is it really worth the extra money for a new mobo?

Answer 1

First off, all the people talking about dual core, BOTH chips in question are dual core, so stop talking about that. As for which is faster, the Core 2 Duo is faster. But there are other things to think about. For example, DDR3 memory will be coming out this summer, which will mean if you want it, you will once again need a whole new motherboard. Plus, by then, the price of Core 2 Duo will have dropped a good amount. So this leaves you with two options, stick with your current motherboard and get the Pentium D now, and then upgrade after the new stuff comes out. Or, spend the extra money for the new motherboard and get the Core 2 Duo, and most likely forego upgrading to the new stuff this summer. Which of those options you choose is really up to you though, but I would personally recommend the first.

Answer 2

I'm pretty sure the "Core Duo" chip is a laptop processor. If you want to buy a new motherboard you should consider Core 2 Duo. Even then E6400 @ 2.2GHz will have no problem beating Pentium D 945 benchmarks.

Even though multitasking is much better on a processor with two physical cores (core 2 duo), it won't help you much in the near future. You will definitely have to wait for dual core compatible programs and games to take full advantage of the performance. Presently the second core takes overload work for the first processor and background processes. Core 2 duo is definitely the better choice though, so I would consider a new motherboard and the new chip. Hope this helps.

It depends on how you are going to use the computer. For general use, the Pentium D is more than enough ooph! But, if you play a lot of games and like to multi task, get a Dual-Core. The Dual-Core with the faster clock speed is the faster processor of the two, Dual-Core means that there are two processors on one chip. So, the 3.4MHz if it is a Dual-Core is faster than a Dual-Core rated at 1.8MHz. The only difference that you may notice in the two chips is the 1.8MHz may have a larger cache, hence the cost will be the same as the 3.4MHz which probably has a smaller cache.

Answer 4

Pure clock speed on CPUs does not mean a lot anymore especially on the Core 2 Duo processors. I honestly would say get another motherboard and the Core 2 Duo chip because it will increase the updatability of your computer a lot.

Here's a few charts to compare cpus:

core duo (not core 2) is a bit slow, typically used for notebooks. Pentium D 945 is a dual core cpu. You might want to look up the maker and model of the motherboard you have now to make sure what it can and cannot support. If your a gamer, it's going to be the video card that is the most important.

Answer 6

CPU % isn't easily measured in MHz and GHz. That decision is basically what number situations the clock ticks each and every second. that is an major area of %, yet no longer the in trouble-free terms aspect. more recent processors have more beneficial transistors in them so that you'll get more beneficial done in each and each and every tick of the clock. the most important degree of CPU % is definitely the type of IOPS (Integer Operations in line with second) and FLOPS (Floating-aspect operations in line with second, or the type of calculations it may do with decimal numbers). regrettably, those are not oftentimes printed as a lot. both.8GHz Pentium D case in point is a twin-center processor utilising the older Netburst layout. besides the undeniable fact that that is were given a swifter clock than the more recent center 2 Duo, the middle layout shall we the processor get more beneficial done on each and every clock tick. so some distance because the version between the middle i3, i5, and i7, there are also some characteristic transformations. lots of the more recent processors have a characteristic suggested as Hyperthreading which shall we them do 2 issues on each and each and every center quickly (besides the undeniable fact that in the adventure that they attempt to do an similar aspect mutually, they ought to attend because they are sharing the middle). the better-end processors actually have a higher cache. you would no longer comprehend it, yet lots of the time you're on the computer, your CPU isn't doing some thing. each and every time it needs to study some thing from RAM, it wastes about 1000 clock cycles. If that is interpreting from the hardcontinual, it may well be dropping one hundred,000 clock cycles. The cache is memory on the fringe of the processor, so it in trouble-free terms takes a pair clock cycles to study. once you've a higher cache, the computer can stick more beneficial stuff in there so it is going to waste fewer clock cycles interpreting from RAM and the hardcontinual. it is likewise why including more beneficial RAM can % up your pc.

Answer 7

Definitely the Intel Core Duo 1.8 MHz.It is more current and will ensure that you will be able to run games that are coded for multiple core processors.

LT : yes. If you want to buy a new motherboard buy one and go with
Core 2 Duo.
