Golden Samples?

10*270 & 10*250 seems to good to be true...

 

[Vegitto]

Yeah, cherrypicked shit. I remember the Venices when they were new. Not a single one under 2700 MHz.

 

[Bona Fide]

Eh...I hope that's not true. Just look at the Venices right now...you can still get >2500mhz.

Yupp but U have two cores on each X2 and the HTT has to be adjusted to the least performing core

I think 4600+ (2.4 GHz) speeds will be achieveable, & that's nothing to complain about

Where's AT's review on this though?

 

[Capt Caveman]

In the TechReport review, they were only able to overclock the X2 3800+ to 2.5ghz. Still impressive.

To get to the real issue at hand.....The 2ghz 3800+ shows once again how sh^tty the P-D's are...It still slaps the 820 around and would have beat the more price comparable 830 as well.....

How low wouls a dual core have to go to equal an 820?? Prbably a 3400+ (1.8ghz) model???

That's easy to measure, Duvie. Just underclock your X2, and compare the results to someone with a Pentium D.

I would be plenty happy with 2.5 ghz, now for them to get under $300 and I am sold. The die size on these are less than the old newcastle cores! That's awesome because they could get cheap

Yeah Lower multipliers are allowed, this would make lowering only the CPU speed and keeping everything else the same easy. I would Like to know how low they have to go myself but i wouldn't touch a 820 and don't know of anyone else that would.

FWIW - A review from X-bit Labs. It compares the X2 3800+ against the Pentium D 830. Overall, the X2 3800+ came out on top but only slightly. Also, they were only able to overclock to 2.4ghz.

[Capt Caveman]

FWIW - there's a guy at ocforums that has a X2 3800+ oc'd to 2.67ghz.

[Leper Messiah]

meh. The reviewers are too conservitive, IMHO. only 1.425v? Thats not enough, esp. when your loads are only hitting 48C on stock cooling. Pop a xp90C and a decent panaflo, and I bet 1.5v and 2.6GHz would be fine.

 

[blckgrffn]

That's my bet too - I would be willing to got to 1.5V+ if it gained me some speed.

 

[Leper Messiah]

If they're defaulting to 1.35, then 1.5 is only 11%. Hell, I'd say even 1.55v would be okay if they had decent cooling...

 

[blckgrffn]

Agreed. An XP-90 and a 40CFM 90mm fan would turn the trick for sure at 1.5V, and if you wanted to, up the CFM on the fan and go for the gold

If they are like the current Venice revision though, once they need voltage to go higher, they need a lot to gain just an extra 100 mhz or so, the gains don't seem linear. Just my observation though

While the X2 4400+ has been extremely excellent IME, I'm very glad to see that X2 multitasking performance has been extended to a budget category that was previously neglected. I don't think anyone who buys an X2 3800+ will be disappointed. :thumbsup:

 

[Zebo]

Anands review 830 gets bent .. only winning 2 tests outta 44. I told you guys a 840EE would get beat by a 3800 chip too.. too bad no sites would diss intel like this

[Stoneburner]

Anybody else troubled by how slow the CPU industry is moving these days? it's been almost 2 years since the fx-51 and a64's originally came out, and i belive the fx-51 was a 2.2 ghz chip? So now they have dual cores... how slow will the clockspeed on these ramp up? Looks like the 4400 is a much better overclocker, maybe i'll wait for that to drop to low $400's.. but that'll take a year in the current state of processor production.

 

[BitByBit]

Considering a 1.8GHz 3000+ has no problems keeping up with a 3.0 - 3.2GHz P4 with HT, it is no wonder the X2 does so well against the Pentium D, which lacks HT.
Smithfield/Presler are not what AMD needs to worry about. Yonah will be out early next year, which will almost certainly serve as more of a challenge to the X2.

 

[Zebo]

Unless I want to install the $160 XP-64 I paid for a couple months back. Seriously, start adding transistors (AMD64/SSE3 etc) to make "the second coming" aka p6 part duex, a more complete chip the power can't stay the same. And is'nt yonah a laptop chip anyway? Nah does'nt excite me yet, Conroe will be the time to buy intel again.

 

[n7]

I now can consider getting one of these, when they come down a bit in price.

I'm a bit disappointed with the OCing results though.

It seems most sites are only getting around 2.4 GHz, & usually they get cherry-picked CPUs, too.

Just stick with your old one...you won't need a dual-core computer until the middle of next year.

Please modify your topic title to include "X2".

Thanks.
