Availability of AM2 SFF X2 chips

[DrMrLordX]

And more importantly, has anyone tried to OC the 35W X2 yet?

 

[broly8877]

no to both

 

[DrMrLordX]

Drat. Btw, the part number for the 35W x2-3800+ is apparently ADD3800CUBOX

http://www.amdcompare.com/us-en/desktop/details.aspx?opn=ADD3800IAT5CU

According to this site, it will have a stock vcore of 1.025v! That's lower than the Turion voltages!

Then there's this guy, selling an X2 with the HE-SFF part number but listing the TDP for the standard X2 part:

i guess u will have to wait some more weeks, maybe months. they are not even listed here in europe and that may or may not mean alot.

If it's got a stock VCore that low, then it means AMD have just cherry picked cores that can take a low vcore, rather than ones that are more efficient at the same vcore - essentially, you'll probably just have to increase it up to standard vcore anyway to get a decent OC.

 

[DrMrLordX]

Maybe, maybe not. AMD did the same thing with the mobile Athlon XP, and those things overclocked very well at what amounted to stock vcore for their desktop counterparts. These EF-SFF chips should have a lot of headroom for overvolting which could make for some nice overclocking (not that they'll be a threat to Conroe). You could probably run them at voltages as high as 1.45v-1.49v on air.

Of course, they may all top out in the 3-3.2ghz range which is about what you get with the 89W X2s.

we don't really know how well the retail conroes will OC so saying that is wrong. maybe the samples ppl have now are cheery picked.

Pulled that one out of your rectum.

Maybe. However, considering the ipc advantage Conroe has over K8, it'd be difficult for a 512k l2 cache X2 to compete with an overclocked Conroe. To match a 3 ghz Conroe, you'd need approximately 3.6 ghz out of an X2 with 1 meg l2 cache per core. Out of a 512k l2 cache/core chip, you'd need approxmiately 3.8 ghz.

I don't think it's a stretch to assume that we'll be seeing a lot of Conroe chips at 3 ghz on air.

The E 6300 is 1.86ghz and costs $183 (could be more thu.) and is 2mb L2. The 3800 x2 is $160 at the time of conroe release. We need to compare these 2, since they are closer in price. The AM2 motherboards cost about $125 for an SLI 570. If anyone interested in price performance, he/she should compare conroe's E6300 in a $125 mobo to A64 3800 x2, same price mobo.
Sofar all the benches are on the high end conroe's and we dont know how the E6300 is going to size up against A64 3800 x2.
I bet an overclocked 3800 2x can beat an overclocked E6300/ $125 mobo.
If so, the price performance is in favor of AMD's AM2's (3800 x2).
The upgrade path is another determing factor. AM2's can upgrade to K8L, but history shows Intel's upgrades always require new motherboard.
90% of end users buy medium range system, and AMD will have this market.
No wonder Forbe advises people to sell Intel stock and run.

Haven't seen any yet, but I'm still curious.

*Edit*
Found one.

I'm going to wait until the X2 price cuts (which hopefully will drop the EE and SFF line in price as well) before I decide to toy with one of these.

 

[DrMrLordX]

Yeah, that's the right part number and right listed wattage, though they have the vcore all wrong. Oh well.

$410 is pretty steep, I agree. I don't have the budget to play with one of these right now.

It's too early to speculate about an X2 vs E6300 showdown, but at stock an E6300 will outperform an X2-3800+ based on performance comparisons we've seen already. 1.86 ghz Conroe = approximately 2.2 ghz X2.

When it comes to overclocking, again, you're gonna need around 3.6.3-8 ghz to compete with the inevitable 3 ghz Conroe overclocks that will turn up. The E6300 is at least going to hit 2.8 ghz pretty frequently, though it may wind up being hamstrung by it's multiplier more than anything else.

That's exactly what they are doing.

I have found a store in Germany selling AMD Athlon? 64 X2 Dual-Core Model 3800 Windsor[35W]
Ordering P/N (Tray) ADD3800IAT5CU 144 euros/ about $176 dollars. I'm going to buy one. If you want one too, I don't know what the payment method or freight charges will be. Email me and I will tell you what has happened. If it's good all who can buy one may save on freight costs if we buy together. vabear@cox.net . It is 2117 hours wed 26th july

I'd buy a 939 3800 X2. Not only are they easier to overclock without running bus speed limitations... they clock better than AM2. Both 939's I've had my hands on could do 3Ghz I will have another this week. I can't even count on one hand the AM2's that can do that... Sure the low powered AM2 3800 are cherry picked but they have a sh1tty multiplier capping your overclock no matter how good the chip is.... could make 3.5Ghz but you'd never know it.
