Presler ships to OEMs

[DrMrLordX]

Saw this on Tom's Hardware's news section:

http://www.tgdaily.com/2005/10/18/intel_q3_2005/index.html

Looks like Intel is moving quickly to bump the 8xx Pentium D's off the market and replace them with 65nm parts. Smart move considering how bad the 8xx chips are.

Isn't Presler the Extreme version with hyperthreading, while Cedar Mill is the regular version?

 

[jazzboy]

I don't think any of the Preslers are going to have hyperthreading this time. However the extreme edition preslers are going to have 1066 Mhz FSB - I believe there will be two EEs - a 3.46 & 3.73 versions.

Standard preslers will be 2 x cedar mill chips. (800 FSB, 2 x 2MB L2 cache) - except hyperthreading of course.

Cedar Mill is the individual 65nm core that is little more than a shrunken Prescott with more cache.

Presler is two Cedar Mills in one package.

Whether or not Presler will have HT enabled or not is unknown to me.

ok here is a quasi-dumb question... i see that Intel's Dual cores are EM64T enabled... but why doesnt INtel push the fact that they are 64 bit more?

because all they did was copy AMD's x64 extensions, since Microsoft said those were the only ones their 64-bit OSes were going to support.

 

[LTC8K6]

No, they used the cross licensing agreement they have with AMD. No need to copy anything, they had it by agreement the whole time.

Dunno why are you sayin' the 8xx series is bad. My 820 runs fast and flawlessly. Not too hot either with a CNPS9500-LED on it (58C tops under load). So? Why is it bad then?

 

[LTC8K6]

Well shoot, then who cares about Presler? It's only benefit is that it might be slightly cooler? Maybe not though since the die is smaller and might be harder to cool.

 

[LTC8K6]

So? Why is it bad then?

Because they can't overclock it very much. That seems to be the main gripe in that thread about it. It runs fine at stock and does it's job well.

While the D820 is handily beaten by an X2 3800, it also costs a lot less than the X2 3800.

 

[Qbah]

Well... Mine runs stable at 3.4GHz (maybe I got lucky ). That's a 600MHz increase from the stock 2.8GHz (~21%). Though I am not into OCing. Prefer to have my system noiseless (tried it once though, just out of curiosity). And yes, the X2 eats the 8xx series with ease. But the cheapest X2 is twice as expensive as the D820...

Die is smallar and harder to cool? wtf are you thinking?????

Give me a pick of dual instances of prime95 or 1 instance of S&M at 100% load running fpu test and show me 58c....Then I will believe it....

What vcore do you have it set at??? If it is 1.4v or greater then it lkely is throttling slightly at 55c....


Big difference is my 4400+ at stock which is good enough to beat a 3.4ghz P-D runs 41c with 2 instances of F@H running...I have an XP-90c...I can take it to 2.4ghz with 1.36v or stock level and only hit 44c under same load....

It will run 10-15% cooler as well as consume 10-15% less power. It will be better and if anything will allow the dual cores to ramp up in speed.

They will only be better cause they will clock higher....They still will have similar head to head perforamnce. they added some more cache which Intel loves to throw at it. Bottom lne they are not HT enabled and therefore they will still not be enough to eclipse AMD X2's as performance leaders.....

Sure you can OC to 3.4 and let it throttle under load until it shuts down. Or run stock at 58c idle.

But I have one, and the best air cooling today (big typhoon) and at 3.43 stable, under load its 53c. Thats NOT cool, and it heats my room up like never before. Duvie has been over here and seen this baby, so he knows too.

Its a flamethrower at 3.43 !!!!

Edit saw you post Duvie. Exactly, tomorrows Intel chip still can't come close to todays AMD chip......

But is enabling HT a good thing, especially when windows runs two threads on one core and one virtual core before the 2nd core is enabled? Lower power+lower heat= better overclocks, so if Intel comes up with a 2.8GHZ 9XX that is priced around 220 dollars, it is defenetly an option for those looking for a budget dual core rig, esp if they have a chance to oc to lets say 3.6-3.7 on decent air without having the horrible heat problems that the current smithfields have.

Thats what I meant about copying. AMD does the same thing every time a new SSE comes out.

actually, the cheapest X2 is something like $100 more expensive right now buying both brand new. Don't quote me any of that e-bay crap, I don't buy used computer equipment there. Add $50+ for a decent HSFU so you can actually run OC'd with out throttling, and it becomes an awfully small difference, considering that the x2 3800 runs with the 840...yeah.

Most people who buy an X2 also buy an aftermarket hs/fan

 

[Markfw]

Why would the new 9xx be cheaper than the old 8xx chips ??? That would be nice, I could dump my 820 for something that won't heat up the house. Or I could save it for the winter, and swap the 9xx out for the 820 !

In some apps their is a nice increase...in others there was a nagtive effect...and still in others it made no difference except for smoother multitasking with 4 cpu intensive threads running...

provide some proof of that...I hink it is about half...I know of quite a few ppl with stock coolers...they are not ocers and that is a big reason...

Differnec is a stock P-D damn near needs aftermarket cooler while X2's running stock even at flagship 4800+ model does not....Reality bites!!!

That was even quoted by Toms Hardware himself in his recent review of these chips...

My 820 ain't throttling, cause it's running at x14 multiplier... And when the higher rated CPUs throttle down due to overheating, they lower their multiplier to 14. Mine can't, cause it's already there. The burn - 58C are at stock speeds with the 9500LED at 5V... so the quietest mode possible. When I OCed the CPU, I upped the FSB frequency to 244MHz (RAM was at 488MHz). vcore was raised to 1.5V. Ran 3DMark05 for 3 hours straight. No hanging/stuff what so ever. And, as I said, it couldn't have throttleded down, cause it can't change the FSB dynamically. Only the multiplier. Was at lowest possible, hence no throttling.

And I ain't using the stock HSF... The Zalman CNPS9500-LED does a superb job with cooling. So no, it doesn't idle at 56C when OCed... Not when I put the fan at 12V.

Well that is the bull you have been fed...I witnessed a P-D throttle and the speed of the core1 was dramatically dropping the higher the temp got...took off the side of the case and temps dropped and cpu speed went back in line with the core 0....With 1.45v set (1.4v actual and 1.37v load) the cpu speed of core0 and 1 started differing at 55c and grew to a whopping 800mhz by the time it hit 69c...It shutdown at 70c and restarted....

Another person has now verified the same thing....


Go ahead and run what I stated and use the S&M 1.73 montior to watch the core speeds closely...

By the way who said anything about idling at 56c???
