E6300 Conroe vs Pentium D 915 Presler

Last response: in CPUs
September 26, 2006 10:42:18 PM

I just purchased a Pentium D 915 Presler from newegg. But I am thinking of returning it to get a E6300 Conroe instead. Is this a good idea? Will I notice an improvement in overall performance? Is it worth tearing apart my computer (I have a water cooler) to replace it?

Are you kidding me?

It's like comparing woman's brain to man's!!!

LoL - is the man's brain more like the Presler?
Too much hurry, not enough speed; also tends to overheat at times...
Yeah it's manly, heheh.
@ jonh123
Just to mention, technically it's Allendale. The two 2MB cache models are Allendale, and the faster big-cache CPUs are Conroe.
But I certainly would not accept a return on a used CPU that was perfectly fine... you're fortunate indeed to be able to still consider the Core2.
Yes you should buy one, but will you not also require a motherboard?
(This is why the guys have already asked you for your spec's)

What do you mean?
I have the highest RE5PECT 4 Bitches :!:

my MB supports the conroe. I'm just wondering if its REALLY worth it to return the presler to get the conroe.

core2>amdx2 64bit>pentium ds

in other words hell yes, and go for the e6400 if u can, its not that mcuh more and is about the same as a fx-62

aww u beat me to the edit lmao

my stuff is good that I have, so its really cpu vs cpu. but I've pretty much figure after reading peoples replies it would be worth getting the conroe.

Well the E6300 is like a D-945 in speed - but more $$ than D-915, so you must decide.

What have you been smokin' :?:

Hey n00bie jonh123,
Either you're not too bright, or you didn't actually read replies, or you're just ignoring me...
Stop calling it a Conroe! LoL, if you're just ignoring me that's okay, I'm used to it.
@ Assman
Well I was just saying, it's apples & oranges - you can't compare Core2 with a D-915! With an A64 x2 4600+ maybe...
The E6300 and D-945 are the same price at my local shop (but I agree with you, still a no-brainer)

LOL, good one

thanks guys for your input.

anytime, keep us posted and overclock the hell out of c2d :wink:

Been there, Doe that. Go with the E6400, or if you can afford it, the E6600.

As for the INDUHVIDUAL that keeps complaining that it should be called an "Allendale" and not a "Conroe", well, he's an idiot. It depends on the date of manufacture and the model number. Technically, all "Allendale" processors are labled E4xxx, which only support an 800 mhz FSB, and "Conroe" processors are labled E6xxx, and support both 800 and 1066 mhz FSB.

Heres are the official details from Intel.

There was contention about the previously available low-end Core 2 Duo desktop processors (E6300, at 1.86 GHz and E6400, at 2.13 GHz, both with 2 MB L2 cache), whether they are specimens of the Allendale core. Prior to Q1 2007, all E6300 and E6400 processors released were Conroe (4 MB L2 cache) cores with half their L2 cache disabled. The Allendale core, manufactured with 2 MB L2 cache in total, offers a smaller die size and therefore greater yields.

Quoted from The Tech Report:

You'll find plenty of sources that will tell you the code name for these 2 MB Core 2 Duo processors is "Allendale," but Intel says otherwise. These CPUs are still code-named "Conroe," which makes sense since they're the same physical chips with half of their L2 cache disabled. Intel may well be cooking up a chip code-named Allendale with 2 MB of L2 cache natively, but this is not that chip.[16]

Another difference between the premium E6000 series (Conroe core) and the E4000 series (Allendale core) is the front side bus clock rating. The E4000 series are rated to run on a quad-pumped 200 MHz front side bus ("800 MT/s") while the E6000 series are rated to run on a quad-pumped 266 MHz front side bus ("1066 MT/s"). The E4000 series also lack support for Intel VT-x instructions.

The Core 2 Duo E4300[17] uses an Allendale core, released on January 21, 2007. The Allendale processors use a smaller mask with only 2 MB of cache, thereby increasing the number of chips per wafer. Allendale processors are produced in the LGA775 form factor, on the 65 nm process node. E6300 and E6400 CPUs have been made from both the 4 MB Conroe die and the 2 MB L2 Allendale die. The steppings of the chip differs depending on the die used- the Conroe-based E6300 and E6400 are stepping B2 and the Allendale-based E6300 and E6400 are stepping L2.

Initial list price per processor in quantities of one thousand for the E4300 was US$163. A standard OEM price was US$175, or US$189 for a retail package. The price was cut on April 22, 2007,[18] when the E4400 was released at $133 and the E4300 dropped to $113. Allendale processors with half their L2 cache disabled were released in mid-June 2007 under the Pentium Dual-Core brand name. The working cache memory was reduced by half again when the Allendale core was released under Intel's Celeron brand; the Celeron E1200 has a 512k L2 cache shared between its two cores.

On July 22, 2007, an E4500 Allendale was launched, phasing out the E4300 model.[13] This was accompanied by a price cut for the E4400 model.
