Core 2 Duo e5200 - does it exist?

I have seen a lot of mainstream vendors selling only a Dual Core 5200. But I have seen a couple instances of reputable vendors selling a Core 2 Duo E5200, and then only in barebones systems.

Does it exist, are these vendors listing it wrong?

E5200 is based on the core architecture and sells as a Pentium dual core for marketing reasons.

this. its a penryn based dual core with only 2mb L2 cache, vs the 3 or 6MB standard in the "core 2 duo" branded CPUs. if you are planning on getting one, its a good chip. i have one running at 3.2GHz right now in a shitty old XFX 680i LT with horrible Vdroop. with a proper board i have heard people getting them to 3.6-3.8 even

Ok, why market it as a Dual Core instead of a Core 2 Duo?

Core 2 Duo has 3mb cache or more. The names are different so the average Joe (the Plumber 😉 ) will spend extra to get a "Core Duo" chip.

You're fimiliar with marketing right?

probably the limit that Intel recommends.


just because you have seen some E5200 do 4GHz and up doesn't mean that "most" will do it

I'm buying one for a build for a friend so we'll sure see how high it will go 🙂

The original E6300 and E6400 had 2MB cache, yet were marketed as Core 2 Duo.

The e5200 is a 45nm chip. Would it then have the instruction set?


Is this what happened? - The Core 2 Duo's were released, then Intel changed what a core 2 duo chip is - in that it need 3+mb level 2 cache (someone posted that there were 2mb level 2 cache core 2 duo's at one time). The e5200 is essentially a core 2 duo - just with 2mb level 2 cache, and they are just going to calling it a dual core. And now, Intel is following its own marketing plan, and some vendors are following a more "aggressive" marketing plan and calling the dual core e5200 a core 2 duo.
 
Its all related to marketing IMO. The latest generation of pentium dual cores(e5200 and E5400) are better spec wise than the first gen core2 duo(4000 series).
But with the switch to 45nm. they changed what it meant to be a pentium dual core and a core2. Just compare them by speed/cache and process and you should be good to go.

I posted that it didn't (none of the E5X00 do). The 45nm Core 2 Duo have them

Different generations, different specifications. The architecture is all the same, the chips differ only in the amount of L2 cache.

Original 65nm chips:
Pentium Dual-Core
e21x0 series (800fsb + 1MB cache)

Core 2 Duo
e4x00 series (800fsb + 2MB cache)
e6300/e6400 (1066fsb + 2MB cache)
e6x00 series (1066fsb + 4MB cache) [also included e6320/e6420]
e6x50 series (1333fsb + 4MB cache)

New 45nm chips:
Pentium Dual-Core
e5x00 series (800fsb + 2MB cache)

Core 2 Duo
e7x00 series (1066fsb + 3MB cache)
e8x00 series (1333fsb + 6MB cache)
 
I hit 3.5ghz on mine with limited testing and not that much vcore since I was doing it with the stock cooler....It would do 3.3ghz all day at not that bad of temps with the stock cooler.....

I imagine if I had placed it in my chilled water cooler setup I would have had a shot at 4ghz based on what it was doing at 3.5ghz.


The thing to remember about this besides the lack of SSE4.1 instructions is the rather low FSB.....

Assuming you have a board capable of such, can't you crank up the FSB to 500Mhz and just use a lower multiplier?

wat. :thumbsdown:

Yeah, I think he's getting a bit ahead of himself. The E5200 can reach 3.6 pretty easily, 3.8 often and 4ghz is lucky. 5ghz is a pipe dream, really.
