Back to Back Dual Core Processor Competition–When AM2 X2 5000+ meet Intel C2D E6400

[windwithme]

It’s 2 months later since 2007/02, AMD have several time price drop actions
this year, AMD enhance their market strategy by lower X2 price and 65nm
processor mass production.

Especially the 65nm 3600+ X2 512K processor, the lowest dual core price
with 75USD, this is great cost with great strategy no matter on new DIY or
platform upgrade market.

These are our 2 competition processors.
The cost between them is almost same, but AMD X2 5000+ keep lower price.

The worriers:
Left side, Intel Core 2 Duo E6400
Right side, AMD Athlon64 X2 5000+

Take a look on frequency info.
Processor
Intel Core 2 Duo E6400:266X8=>2133Mhz
AMD Athlon64 X2 5000+:200X13=>2600Mhz
(Motherboard small frequency difference with 2612MHz )

Memory
BIOS Setup will all be DDRII 800 CL3 3-3-9
AM2 processors have some ratio divide issue,
so the real frequency is DDRII 746 CL3 3-3-9 1T

Besides the platform with different motherboard and chipsets, rest of the
components is the same.
I use NVIDIA chipset on both side, that will be more similar with fair
competition.
But still have little difference between Intel nForce6 and AMD nForce4, since
the nForce6 is newest version.

Memory

Intel:7680/4861/5426 MB/s 58.6ns
AMD:8005/7271/6130 MB/s 47.1ns

AMD is strong on memory bandwidth performance,
since the frequency is only DDRII 746,
but all memory test results are better then Intel with DDRII 800 with same
latency.

Here are my personal opinions:
First of all, I was mentioned before, the K8/AM2 architecture performance
gape is about 400MHz higher to equal compares with Intel C2D.

Second, because the difference architecture, the best cache performance
rate is about 512K, C2D is about 2MB, more cache will only have less
percentage enhance.

Let’s recall our memories to last generation, P4 3G V.S. K8 3000+ competition
on 200USD segment, but P4 3G is worse then K8 1.8G, the overclock
performance is also less then K8 overclock improvement. Now the situation is
different.

AMD is very cleaver in these months with great price strategy,
If user can have 400MHz more AM2 dual core products with better price ,
then AMD will have more advantage to beat Intel C2D.

But Intel C2D got the advantage on overclock range and performance,
normally can easy overclock up to 3.4G~3.8G limited.

AM2 just lead in with 65nm design, extreme frequency is about 3.1G, if the
limited can up to 3.3GHz higher, that will help to deduce the performance and
overclock gape.

AMD comes with lower processor and motherboard price, that’s the advantage,
But for long term business, they have to enhance the frequency limited and
new architecture, that’s the solution to fight back the behind situation now.

Any way, the hard competition will benefit all end users to have lower price
and higher performance.

About the extreme overclock, already had many reviews to know on internet,
this time we take a look on normal user situation with same price segment.
Let’s expect next wave price/performance competition between Intel and
AMD.

Awesome review.

[DAK1640]

Great job windwithme :banana: :banana: :banana:

[LordofDoom]

Good job yet again!

So are these the same price!?

[TEDY]

excellent review many thanks

[PanteraGSTK]

This is a very good perspective on how amd and intel relate. Price/performance is very close now. If only the amd cpu's could oc like the c2d's. Me thinks amd may have something up their sleeve.:stick:

[Okda]

very sad to see intel beats amd in memory score in 3dmark 05

[Kasparz]

Brisbane is bit slower than windsor due to slower cache. x2 5200+ windsor would be faster than E6400 in most apps, and cost even little less ATM.

[TEDY]

yes but they do oc nice i think. brisbane that is.

[4Qman]

Superb Review, clean and well detailed out. :toast:

So INTEL win the performance and AMD retaliate with cheap chips. Only one will keep the enthusiast though. :cool: That will be Intel as we all know Clockers go with speed and not price :) However close it is at stock, end of the day "who runs stock" :p:

Again a great review windwithme

[mukmaster]

Nice review !!!!

[erwinz]

nice job.. :D your very busy my friend.. :)

[ferrari_freak]

Really nice. Too bad most people are willing to spend the few extra bucks for the performance. And OC results for the C2D blow AM2 out of the water. Maybe AMD can redeem themselves over the next few months...

very nice review, keep up the good work :)
