Intel Processor question?

[riverider]

The intel Pentium D 940 has a clock speed of 3.3 Ghz and a front side buss speed of 800Mgz.

The Intel E-6400 has a clock speed of 2.3 Ghz and a front side buss speed of 1066 Ghz.

Whats the better Processor? Is the faster front side buss speed more important then clock speed of the Processor?

Seems many major system builders are replacing the Intel 940 with the E-6400.

The Core 2 Duo (e6x00) is the better processor by far.

It's hard to be exact as there appears to be no exact comparison between the two but look here:
An E6400 at stock speed beating an Intel 965 extreme edition by 18points in Worlbench 5, a general performance benchmark.

Look at the many other indicators/Benchmarks

The Core 2 Duo (aka Conroe, E6x00 series, what have you) is far and away faster than the previous generation Pentium 4 or Pentium D CPUs, even at lower clock speeds. I haven't seen a direct comparison between the lowest-end E6x00 and highest-end Pentium D, but I doubt that the Pentium D would be significantly faster, if it were faster at all. The only reason to go with a Pentium D over the E6x00 line now days is price (and the E6x00 lines aren't that expensive to begin with).

I know there has been some direct comparisons between AMD FX62 and Conroe E6600 and on paper they are very similar at stock speeds but when you think the FX62 is twice the price of the Intel chip you start getting a perspective on just how much of a leap Intel have made.
Then consider the E6600 soundly beats the FX62 when both CPU's are clocked (apparently by as much as 20%) then it's even more impressive.
So if the E6600 can do that, the faster E6700 and
6800 extreme are possitively streets ahead of anything AMD or Intel has previously been able to muster.

The story however may be different with the Allendale E6300/6400 models, they have only 2meg cache and I suspect there will be some overlapping (in terms of performance) when compared to AMD parts.
Something like? E6300 being roughly comparable to AMD's
X2 4400 and the E6400 somewhere close to the X2 4800 perhaps, we will see.

So who gets helped by using the E-6400 processor? And just where doe it really show this improvement?

Here is a pretty good article comparing the E6300 & E6400 to AMD X2s. Those who are into overclocking will surely like these graphs. The pricing is a bit outdated already...

riverrider,

You're going to like this one. It's an interactive compilation of benchmarks that let's you select the CPUs and the category:

In addition, you'll probably want to read this article to get a better understanding of what the Core 2 Duo is all about:

http://www.tomshardware.com/2006/07/14/core2_duo_knocks_out_athlon_64/

Just as a brief overview, I will say this. The Core 2 Duo runs cooler, quieter (CPU fan spins slower), eats less power and knocks the socks off of any Pentium 4 or Pentium D out there. The Pentium D 940 you're looking at won't come close to the E6400 in any benchmark. Just for sh*ts and giggles, I compared the 3.6GHz 960 against the E6400 and it lost by as much as 25% in many benchmarks, and more than 15% in all the rest. You can only imagine how much worse a Pentium D 940 would do. So hopefully that answers your second question...

But at this point, the Pentium Ds are the better buy for the price. Unless power efficiency, noise, and heat are a particluar concern of yours, you'd be just fine with a Pentium D...
