E6300 Question

[Meefle]

How does this perform compared to like a X2 3800+? I kno the multiplier on the E6300 is really low, which leads to a mobo that needs to handle high FSB in order to OC alot. The 3800+ will be about $10 cheaper and i'm just wonderin which to go for.

I will also be OCin with a scythe ninja (or miner dependin on if i can mount it for AM2).

From this review:

http://www.hardware.fr/articles/623-12/intel-core-2-duo-dossier.html

The E6300 would be a tough competitor for the 4800+ at stock.

[Meefle]

wow i really wish i could read that language, looks like stock 3800+ isnt that far behind. Maybe an OC to like 2.4-2.8 range could make it even if not better.

[accord99]

wow i really wish i could read that language,
It's only French, and the benchmarks should be easily recognizable.

Well, since the E6300 matches up with the 2.4GHz 4800+, you would only need about 2.6GHz... but why can't you overclock the E6300?

[Meefle]

I never said you couldnt, but with a 6x multiplier and air cooling, it'd be easier with the 3800+ (9x multiplier). To get to 2.4Ghz with a E6300 would require a 400mhz fsb (i'm pretty sure). It'd be easier to OC the 3800+.

About the french..... whooops guess i didnt really try since i can speak alittle french...... my bad

The E6300 multiplier is 7 right? So that makes 3GHz quite possible.....

[[XC] DragonOrta]

2.8ghz would require 400fsb, 2.4 would require around 343fsb, which sould be no problem at all. It might be easier to OC the 3800+ to a certain speed, the E6300 would be much MUCH better performer. And you have a 7x multi, not a 6x with the E6300.

[Meefle]

Well someone on here tested a E6300 besides fugger, fuggers was 7x and the other guys was 6x and he said it was due to some wierd thing that sets the multiplier down to 6x when idlin. But if its 7x then i might just get the E6300 over the 3800+, we'll see wut happens with RHT and all the other stuff.

The guy say a feature called EIST brings the multi down to 6x when cpu is idealin....... whats the point of that?

I think it started out to save battery life in laptops.

Save power and cut back on heat. You can turn it off in most cases

1866/266 = 7

975X Bad Axe is usually good to around 450 at best, 450*7=3150 is still quite respectable. If at 1.86 it holds its ground against the 4800, then at 3.15, it should be unmatched by any X2 on air.

[Absolute_0]

at 3.15 it would be more comparable to an FX60 @ 3.78 GHz (assuming conroe as 20% faster clock per clock)

[CedricFP]

This is looking like an atractive option while waiting for Kentsfield.

Core2Duo based on Allendalde (E6200/E6300/E6400) doesnt have the EIST

[matt89]

ill be getting an E6300 i think

[Karak]

Based on that french site, even E6300 looks really good, performance loss about 1-8% from L2 cache isn't so bad - it still beat A64 under even lower speeds. But there are some things to notice - Conroe architecture have some weakness too, some apps which liked Netburst won't be faster on Conroe ( I mean X6800 vs P D 3.73 Ghz Extreme), and gains from 64 bit are very small esp. compared to P4 - in most cases A64 will regain some % there. On some other site I have read that it is quite weak in encrypton too(vs P4). Good thing is slower memory doesn't hurt Conroe as much as A64. Taking all into consideration it is still best we have seen so far - but keep in mind it isn't equally superior in every area.

[TarTheDark]

You forgot something very important: virtually no software is optimized (yet) for the Core 2 Duo and still it performs brilliantly!

No processor architecture is superior to every other one in each and every benchmark ;)

and don't needed :)

[pcoffman]

On some other site I have read that it [Conroe / Core 2] is quite weak in encrypton too(vs P4)Encryption and decryption appears to be a weakness of Woodcrest, possibly of the Core microarchitecture in general. See the benchmarks on this page: http://www.anandtech.com/IT/showdoc.aspx?i=2772&p=5.

Benchmarks show a slower clocked Opteron keeping up with Woodcrest. The Woodcrest is licked by an Opterion 880. I believe that's a 4 socket, 8 core Opteron. And by a Sun server.

That being said, the author of the article points out that this weakness is "rather insignificant to most people".

These benchmarks, however, indicate that a previous generation Xeon performs much worse than Woodcrest at encryption & decryption.

[matt89]

i think that weakness will only affect a small amount of people

[pcoffman]

Encryption/decryption software needs to be optimized using SSE2 integer instructions insteed of old x86 style (BSWAP, XOR). Then Conroe will realy shine.

That's what this site says:

"The Intel Xeon 5160, a.k.a. Woodcrest, will simply be the most powerful server CPU this year ... The new Xeon is however not invincible ... RSA, AES and other benchmarks clearly show this. Intel will still have to convince some software vendors to port to SSE if it wants Woodcrest to be the completely superior CPU (http://www.anandtech.com/IT/showdoc.aspx?i=2772&p=11)".

[matt89]

they just might be right

[kl0012]

they just might be right

Actualy it was already in some way optimazed in the PCMark05 test:
http://forums.guru3d.com/showthread.php?t=185555

Opteron 165 @ 3GHz:
File Encryption 61.5 MB/s
File Decryption 51.6 MB/s


Conroe @ 3GHz:
File Encryption 94.6 MB/s +54%
File Decryption 94.9 MB/s +84%

[m0da]

i'm sure in the end conroe will be the better performer compared to an overclocked 3800+. The relatively small oc you'll get with the conroe will put the oc'd 3800+ to rest.

but... there might be an exception.. what cooling do you plan to use?

[fluffysheap]

This is a mistake, 6300 and 6400 have EIST. The only difference between Conroe and Allendale as far as I know is the amount of cache, 2MB instead of 4MB. But with the lower multipliers on these chips it doesn't do as much of course because the minimum multiplier is always x6.

I will be usin either a scythe ninja (if those caps on the mobo arent in the way) or a scythe cool miner (If the caps are too close, i'll buy this). So just air cooling.

[BulldogPO]

I'm also planing to buy E6300 and Asus P5W DH, I allready have Scythe Ninja plus.
I'm hoping it will fit.

[Meefle]

Yea i have a ninja now too. I'm hopin it will fit. I wish someone would test it out.
