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.

What do you mean by the cpu industry being "slow"... I have to disagree..
Here we are with the technology to have two CPU cores on one single chip.. Both companies have stated they are going to be concentrating more on dual cores.. and eventually Quad core.. and more... SMP is the future.. you can only ramp clock speed so high, before new technology has to be invested in..

I must disagree with Zebo. I am very excited by Yonah, though I'll be shelling out for the 3800+...

Still, AMD needs some competition for the performance crown, and Yonah is it

IMO anand and Xbit labs artices were more fair to Intel. Alot of sites did 820 Vs. 3800+X2. Guys, there is now no reason not to get the x2! Get one now!!!!!!!(wait till the price gouging stops)

Also, the 2.4 result was not typical. They probably just got a dud 4600+ or 4800+ what was marked for the 3800+ graveyard. Wait a few weeks (1-2 months) until all the duds are sold, then jump in when the prices are finally ungouged and the chips aren't duds anymore!

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.


Uhhh, since when do you know what i need

I do alot of gaming & video encoding...& i'd like to be able to do that simultaneously.
Or at least use the PC while encoding, something i can't do right now sadly.

In terms of overall performance the CPU market is not advancing as fast as it was. Look at the GPU market where there is a doubling of overall power every 12-18 months.

From the post I placed earlier about the guy with the X2 3800+, he got his for $379 at Fry's yesterday and has his stable at 2.67ghz

Well, I am going to get one. Then I can bench against my 4400 !

Nah does'nt excite me yet, Conroe will be the time to buy intel again.

I'm pretty excited about Yonah, especially since it looks like that's what Apple will be using in their next gen Powerbooks. The prospect of dual core mobile OS X goodness (possibly with the option to dual boot into Windows) makes my mouth water.

I go through laptops like cell phones ( a lot due to breakage and loss) so give me a disposable celeronM and a text editor/movie player and I'm happy. Desktop is for real apps and fun. IMO.

I want to get one with a chepaer NF4 nobo and a 6200 for my son....He only needs one core for gaming but I will pick up another FH core for the same price...2 when he is not gaming...My TT Venus 12 will do and I will likely not OC it beyond stock vcore....

Guess that 3000+ winchester of mine I will sell or trade to get a mobo or perhaps a 6600 PCI-e card...

Screw that duvie give him the 6800 and your MSI and get a new card and mobo for number one. Start running the numbers and you'll like it.

I've seen PCIe x800xt's for $270 and 6800GT's for the same in hot deals -- 7800's are dropping like rocks less than $500 and NF4 mobos are better all around. I was faced with simliar delima but I'm tired of holding on to a dead AGP port.

That will slow down a lot I'm sure. 2 7800's are a waste if you don't have a 20" wide screen display. Sooner or later the guys that buy the bleading edge stuf are going to figure out that their paying $20 per frame, and that 100 fps looks the same as 50.

Why did Ananandtech compare the 3800+ to the 4200+ in power consumption? The 4200+ is not a Toledo core. Its a Manchester core. If they wanted to compare X2's they should of compared the 3800+ to a 4400+ or 4800+ because those are actually Toledo cores with 2MB L2.


Read the first page again. Text The X2 3800 has 512KB x 2 L2....

They are Toledo cores with disabled 512KB cache! Still Toledo...

And the difference from a Manchester to a Toldeo in terms of transistors is all related to the added cache....So in conclusion turn off 1mb of cache (512 per each core) and it walks and talks like a manchester...For all intensive purposes it is a Manchester....

PLus do you have definitive proof these are toledos with defective cache??? I mean many of us threw out the theory, but where is the DEFINITIVE PROOF???

The transistor count of the 3800+ goes down to 154 million, and the die gets shrunk down to 147 mm2 compared to the 233.2M and 199 mm^2 of its bigger brothers (4800/4400+). The thermal envelope of the new core also dropped from 110W down to 89W

The Toledo's die size is 199 mm2
The X2 3800's die size is 147 mm2

its not about need, its about if you can use it. You probably don't "need" anything more than a 1GHz P3 and 512MB of ram, but that's no fun and hard to get some serious work done.

People don't multitask now because even a P4 with HT isn't that great of a multitasker.

Being able to do everything you used to do at full speed and then having another core to put to use is a big advantage. I think people don't realize it because they've never had it. Like people in the time before fire, they never cooked stuff because they never knew it or thought they "needed" it, but once we started doing it...well now we get sick and die if food is undercooked.

I think the people who appreciate dual core the most are those who have been using dual CPU rigs since they were available/practical. Dualcore is more apealing because it offers greater performance AND is more cost-effective. Dualcore chips usually aren't just twice the price, then there's no need for a special motherboard (unless its the PD ), then because the motherboards are so common you get common support and features such as PCI-e and SLI and all the good stuff single socket enthusiast baords can boast such as insanely fast/overclocked NON REGISTERED/ECC RAM - a big drag on performance if your data isn't mission critical.

K nvm, I was thinking about my X2 which is E6 or something, not the manchester but Toledo core with bad cache... I thought that confusing part of Anands article meant that all 3800+ were Toledos but after careful examination, they were all designed to be Manchesters.

Edit: wasn't sure now know E6

Where in the world did you come up with that conclusion. I could have used dual core TWO years ago.

Would MSI's compatible CPU list count?
