processor diffrence?

Question

Im upgrading my processor and what is the diffrence between

Intel Dual-Core E2140 and the
Intel Core 2 Duo E4300


with the expection of the 50 dollar price diffrence. Will it be worth it to pay the other 50 dollars and get the core 2?
Misc. info
Im building a semi decent gaming comp, not just a web browsing comp.
Please dont just paste specs, cause I can grab the specs off the internet as well.

Answer 1

Sam is wrong, BOTH are based on the new Core Microarchitecture, in fact both are based on the exact same core, just with two differences. The E2140 is at 1.6Ghz, while the E4300 is at 1.8Ghz. Secondly, the E2140 as 1MB of cache, the E4300 has 2MB of cache. Both of those differences favor the E4300, it is the one to go with of the two, especially since cache is valuable for a gaming rig.

EDIT: djfear is also wrong, both are based on 65nm technology, like I said, they are the exact same thing except for the two differences I listed. No such thing as an E4350 that I am aware of.

Answer 2

The first is just two P4 chips on one die, and the second uses the new Core 2 architecture. The new architecture is WAY faster than the P4. They're both dual core, but even at the exact same clock, the Core 2 will blow the other one away.

As another user stated, the Core 2 has more cache memory, which definitely helps, but that's not the biggest reason that the Core 2 is better. It's a completely new design, and it shows! That's the one I recommend go with. And I hear the Core 2s overclock great too. Supposedly if you get a good chip, you can get a 2.4Ghz chip to go over 3.0Ghz, without any voltage increase.

Answer 3

along with more L2 cache, the C2D uses a smaller 65nm transistor process. This produces less heat making the C2D a great overclocker. I have a E4400 that I OCed right out of the box to 2.81 ghz (could go much higher if I had a decent board) I would definately go with the E4300. Look for a 4350 if you can find it. They are about the same price and the E4350 OCs better and has even more cache.

Answer 4

The E4300 has an extra megabyte of cache memory, that makes it worth it to me. Cache memory is the fastest memory in your PC, when this gets full the CPU has to do some potentially expensive memory moving which can slow performance. I just got a Core2 recently with 4MB L2 cache (!). Needless to say, its performance is sick.

Cache memory is easily the most desirable factor in a processor. More so than clock speed.

Answer 5

The way I understand the difference is that the cor 2 due is as it says two sets of double cores on one chip, technically it should push stronger than the normal dual cor for this only has two cores on one chip...
