e5200 vs e7200

[PieIsAwesome]

I'm putting together a shuttle system using a G31 chipset, which apparently does not like going beyond 333, and from what I have researched may not have a 1:1 memory divider. I may have to use a 4/5 divider, and may be limited with cheap PC6400 DDR2 that I ordered. Then there are also power and heat limitations being reason for not increasing voltage.

Because of the divider problem, I may only be able to raise the FSB to 320 in order to keep the ram at 400, and because of power and heat issues, I only want to run the CPU at stock voltage.

With these limitations, which would go higher?

Of course, because of the SFF design I may run into heat issues before any of these, and then the ram may only operate under 800 mhz using 2.0v, requiring more power (though I think the PSU should be enough, and I am fairly sure the board supports it), but ignoring that for now. . .

I already ordered the e5200 as I got a deal, but I can always sell it and get an e7200, though I'm not sure it would be an improvement, given the limitations, but with oc limitations at least I would have an extra 1 mb of cache.

e5200s tend to top out at about 3.0-3.2 range at stock voltage (generally in the 3100 area, 3200 is rare). Dunno where e7200s get on stock voltage, but they should be able to get to where your 320 FSB limit is (~3.05 GHz)

Overall the e7200 would perform slightly better, but maybe not enough better to justify almost 50% more cost than the e5200.

You shouldn't have to worry a ton about bumping voltage a bit on the e5200 to get it stable at 3.3 - 3.5, you can see here that an e8200 uses over 20W less power at the same speed as an e4700 (allendale core). If you're willing to give an e5200 a small bump in voltage (0.05 to 0.10v should get you in the 3.4 range, mine goes all day at 3.5GHz +0.1v.

It's likely that an e5200 would be lower power than a default speed / voltage e4700 at 3.33 and the small voltage bump to get it stable there.

So if you are comparing an e7200 at 320 FSB to an e5200 in the 3.1 GHz range, the e7200 will be marginally faster, but a little more expensive too. Definitely not enough difference to warrant the hassle of selling an e5200 and buying an e7200. If you're willing to bump the e5200 voltage a tad to get it into the 3.3-3.5 range, then you're better off with the e5200 anyway if you're limited to 320 FSB.

Edit: I had the wrong link on my clipboard... oops.

You can try doing a BSEL mod to the CPU to fool the motherboard into defaulting to the next higher FSB and giving you extra RAM ratios.

Zap is just dying to mod one of these E5200s -- he's had 'BSEL mod' on the brain all week!

 

[MyLeftNut]

With all those limitations, sounds like the e5200 would be easier to work with. These chips hit a FSB wall between 320-380 depending on the chip you get anyways. Although, like one of the posters mentions about the voltage required is an inconvenience. I'd say stick with the e5200, and if required, you can do the BSEL mods for FSB and voltage.

Of course!

Heck, I'm considering buying one ($80 shipped at Newegg with coupon code) just to mess with it.

EDIT: Alright, bought one. $78.99 with free shipping after coupon code.

Moreover, 45nm Wolfdale core used in Pentium DC E5200 CPU has a number of microarchitectural enhancements. As you already know, it supports SSE4.1 instructions, features Fast Radix-16 Divider unit accelerating the division and square root calculations, features Super Shuffle Engine mechanism speeding up processing of those SSE instructions that require shuffling. It also works with memory using optimized algorithms.

It says that E5200 supports SSE4.1. Then just below that paragraph, it has a chart, and the chart says "SIMD instructions support MMX, SSE, SSE2, SSE3".

Oh well, it sucks that it doesn't support SSE4.1, but it's not really that useful yet, if ever, so not a huge loss.

don't know about e5200, got a e7200 that tops out at 3.52@1.35v 5hr Linpack or about 3.6@1.35v 4hr prime+4hr occt. I think they both the same in terms of max OC potential. Just e7200 has more cache, bit faster at some apps/games.

hrmm i'm planning to get the E5200... what are the odds of it reaching like 3.8 - 4.0 ?

LOL!! :laugh:

And I'll bet you still have a handful of E6850s left from the 5 you bought from the Dell 'giveaway' this summer right?

All depends on what kind of voltage you pump through it. If you want to stay safe, then it probably can't. Otherwise, it may be able to on the right board with the right voltage.

 

[Kraeoss]

planning on using this board.... and 2 gigs of corsair xms2 4-4-4-15 ram but with the upcoming price cut of the e7200 do yall think i should get the latter or continue with getting the e5200 ?

 

[nerp]

I would go with the E7200, personally, since I don't like the voltages that people have been using to get the E5200 to 3.6 to 4 ghz.

 

[Kraeoss]

one thing though what's up with the E7300 ? why was there a $10 price cut on the others and a $20 cut on this.... ? is that chip not as good as the E7200 or better ?

 

[nerp]

It's the same but with a higher multiplier and faster stock clockspeed. Pricing varies by vendor but Intel's pricing model can sometimes seem weird with huge jumps in price on some models for only marginally better performance.

3.8 - 4.0 is kind of pushing it for those chips. I would say 3.75 is probably the max. That's what I got with 1.4v, and so did my friend. 300FSB.

That sounds about right, Xbitlabs got 3.8GHz @ 1.408V: http://www.xbitlabs.com/articl...dc-e5200_11.html#sect0

So from the looks of it the E7200 can generally do ~200MHz more at the same voltage.

Why, I do. Two of them NIB, and soon I will free up a third (used for a while) because I'm replacing it with an E8400 that I just got.

yah i see it like this for the average stable max speed at 1.4v w/ aftermarket air cooling.

e5xxx 3.8
e7xxx 4.0
e8xxx 4.2
e8xxx E0 4.4

+/- Give or take a little. :laugh:

of course, this would make sense because it's all the same core (wolfdale)binned under a marketing moniker.

 

[Jyve]

I haven't seen too many, if any, of the recent batches of e7200's hitting 4ghz. A lot are struggling to hit 3.8 @ anything less than 1.4v myself included.

 

[Tempered81]

ah okay, maybe like this then:

e5xxx 3.6
e7xxx 3.8
e8xxx 4.1
e8xxx E0 4.4

I'm at 3.8 with my recently purchased Fry's $80 E7200. CPUZ reports 1.288v at idle.

 

[Kraeoss]

ok so suppose i take the 'unsafe' voltage path how long u think an E5200 can go @ 1.4+v ?

 

[PieIsAwesome]

Argh, the G31 bios seems to be limiting the OC. With the 200 mhz FSB e5200 I am only given 1:2 and 3:5 options. I'm guessing the 4:5 was only available for 266 CPUs, since the OC with this barebones that I found online was done with an e6320.

Guess I am stuck at 240/3.0 ghz...that is unless I do the mentioned BSEL mod, which I will consider depending on how bored (and brave?) I am.

For comparison, it would seem that the e7200 would allow me to go to 320x9.5=3040mhz with the 4:5 divider. SO without modding I am missing out on 40mhz and 1MB of cache. Oh well, cheapo $65 chip.

The cooling on this thing is weird, or maybe I did a poor job mounting the heatsink/applying AS5, but my idle temps at both stock and OC are around 50-52 and my load temps for stock and OC go up to a limit of 58 for one core, and the other around 55. I'm guessing the fan speeds itself up and down to keep the temps in the 50s, and does not let the temp go beyond 58. Both speedfan and coretemp agree with each other.

There doesn't seem to be a manual fan-speed setting other than slow, low, med, high, or max, and max is LOUD, so I guess I will leave it at auto.
