Intel Core 2 Duo vs. Pentium 4 HT?

Hi,

I plan to buy a DELL laptop with Intel® Core™ 2 Duo processor T7400 (4MB
Cache/2.16GHz/667MHz FSB, 256MB graphic, 1G of ram) to replace my desktop (2.8Ghz HT Pentium 4, 800MHz FSB, 64MB graphic, 512MB of ram) but i don't know how much faster will i get? How much more speed do i get vs to my old desktop? Is it a good replacement? Please advice. Thanks.

How fast was 2.16Ghz Core 2 Duo if it was in P4 HT term (because i used to P4 term)?

 

What sort of applications/programs will you be running? You will definitely see some sort of speed increase, especially since the newer system has 1GB RAM.

 

Core duo should be more efficient and fast at processing and multitasking. Though the p4 has more ghz, it can't multi task with as much is. Also, the 4 mb cache is pretty awesome.

 

i probably using alot of video editing and multi tasking. How about burning 2 dvds at the same time (w/ 1 ext. burner, both will burn at 4x speed)? My desktop couldn't done it, even i close all the applications. Also, using to watch dvd on the go, i will upgrade to 9 cell battery. I heard that it will last around 7-8 hours, is it correct?

 

I know that from reading a comparison chart somewhere (cant remember) that my 2.16 core 1 is about equal to what a 5GHz P4/ht would be if it existed. So yours should be a bit more since its core 2. You really dont have to worry, you have the second best notebook processor in the world there, it will blow anything away with ease.

 

The new CPU will be a lot faster for that kind of usage. It's a lot faster for anything, but especially if you try to do such tasks that actually benefit from dualcore systems, and require high CPU performance.

Hyperthreading is little more than a marketing gimmick. It's nowhere near the same as having two cores. It's a badly implemented feature that doesn't really provide much extra performance, even in the ideal case.

 

The only places where I have ever seen the benefit of HyperThreading is in multi-threaded games and in rendering tasks, where there is a 25% and 15% performance gain respectively.

You will definitely see a nice performance boost with the dual-core CPU for your usage.

 

Just think of Dual Core processors as a bit more than double its clock speed, so 2.16GHz = approxmiately >4.5GHz when comparing it with single core processors. Depending on what your doing, if its regular tasks, then RAM amount and speed makes a big difference, as well as Hard Drive rpm. So try to get 667MHz RAM, Dual Channel if at all possible for notebooks (1GB is enough, 2GB is great but may be pushing it because you'll see very little performance gain and 2GB Dual Channel 667MHz RAM is too expensive for the tiny performance gain), and a 7200rpm Hard Drive. You wont need to use your dual core processor's full potential (almost ever) because in gaming, your video card will definitly be the weak link. You'll only need a fast processor for video encoding, etc.

 

For comparison's sake, my XPS has a 3.4GHz P4 w/HT. My SuperPi (2M) is in the low-to-mid 2min range. The new Core 2's are clocking in at 1min and under.

Granted, actual performance difference likely won't be that drastic (though I will be able to tell you better after my nc8430 arrives tomorrow!!), but the Core/Core2's are significantly more powerful and efficient.

 

Thanks for all the replies, really appreciated. I will get it to replace my desktop since it's more powerful and also have ability to go portable.

 

c2d vs p4 ht is like night vs day. My core duo 1.66 does everything I did on my old p4 3.2ht and then some with room to spare. You will be very happy with the performance boost.

 

Really happy to hear this. Thanks.
