Intel Core Chip Bugs May Affect Macs

Intel Core Chip Bugs May Affect Macs

by , 12:25 PM EST, January 23rd, 2006

Intel's Core Duo, the chip that powers the new iMac and MacBook Pro, has several errors in its code, according to Geek.com. Based on documentation from Intel, there are 34 known problems in the chip. Some problems cause nothing more than a minor hit on performance, but others can cause problems with memory handling, or even result in a system lock-up.

Of the 34 problems found so far, only one is scheduled to be fixed: An issue where the processor's thermal sensor could stop updating. ALthough highly unlikely, it is possible that hardware damage could occur if this sensor stops functioning.

Another problem can result in a laptop failing to wake up from sleep mode because the memory pointers reference the wrong location when waking up.

It's not uncommon for processors to have errors in their code, and in many cases they can be worked around through special coding in the applications that we use. The number of documented errors in the Core Duo chip, however, is a bit higher than expected.

Since the Intel-based iMac is just now arriving in users hands, and the MacBook Pro won't ship until February, it's unclear if any problems will surface as a result of the code flaws in the Core Duo chip.

There it is. We were all waiting for this I think. Don't buy the first gen of a new technology like this. Let others get the bugs worked out for you.

this is not because the iMac is the first intel mac and I don't think waiting for another chip will change anything, because this is a common problem with all chips (not only with intel chips) ...

That's the main point for me. As the article says, these types of errors happen all the time. The only difference here is that there are a few more than usual.

Well...if they can work around, let's say 10 errors on a different chip, then maybe they can find fixes for 20 errors on this one. As long as they find work-aruond fixes for them, who cares if there's 10 or 20? More work for them, yeah, but not me.

Until they come out with a report that says "Error X causes Y to happen and they can't fix it!" then I'm not really worried. All we know now is that such a report COULD happen in the future. Well, gee, that's always the case with any technology!

This is a good article, I'm glad I read it and know about it, but I'm still buying an Intel iMac today, for the record.

Basically, there are still those out there who can't STAND the thought of Apple succeeding, and maybe making headway against the crap that is Microsoft. I view this as another article put out as quickly as possible in order to instill doubt in the minds of those who might have been thinking using a Mac would be a Good Thing.

I just love the timing of it all....

Subject: Common Problem

This is common for all processors and micro-processors. I work with them in the aerospace industry. All processors come with an errata of known issues. Most of them can be designed around.

Personally I would much rather see a list of 32 items on an eratta then a blank list. If the list is blank it means they have not done a good job testing the design because they have not found any problems and the product is not mature.

A healthy list of items on an errata reflects maturity.

If you guys don't know it, there are bugs in chips all the time in various steppings of various chips.

You are exactly right. From misleading headlines. To just plain misinformation Apple FUD is everywhere. There are so many examples. C/net. the inquirer, macworld Uk for a while, The boston newspaper, still pissed at Macworld moving, The Washington Post? Many others that you can find on Macsurfer. What is it with internet journalism and it's uncontested inaccurate reporting. How can one stop it? Because it is much more damaging than it seems. I think only a concerted effort to contact the advertisers on those sites and say we're not buying products en mass would change things pretty quick.
This article doesn't really fit into that category. Sorry for the rant

Intel-based Windows PCs and Intel-based Macs will both have the same processor flaws. Which one will crash? Right, the Windows PC.

....The Washington Post...


I have to dissagree with you there. Anyone who reads Rob Pegoraro's articles and chats can clearly see that he's as "pro-mac" as you can get while remaining a good tech-reviewer.

I mean, he has to point out the bad with the good or he'd be a bad reporter. But time and again Rob's shown that he really likes Macs and has always been fair to them.

Yes, his latest article suggests that you might not want to buy the Intel iMac right now, but haven't I seen the majority of Mac-fans on sites like this one say the EXACT same thing again and again? Rossetta is very cool, but if one can avoid it that's even better. Besides pointing that fact out, the rest of his article is positive.

Anyway, this is too long a post for this one topic but I think it's worth pointing out that the Post's tech guy is a good friend to the Mac community and his paper shouldn't be showing up in lists like the one you've made here.

Yeah - don't know a lot of the history of this particular author - I just found it interesting how quickly something came out with a negative light on a new Apple product with significant change for the future.

I mean, seriously, many people only read headlines, and if they do click a link to the story, read maybe half or so. There's just not a lot of individuals who take the time to really parse things.

And even if they did, they'd have to have prior knowledge that there are "always" errors in chips. I didn't have that knowledge, and I'm pretty geeky... soo... average joe who knows what they think...

But thanks for pointing out the history of this particular person. Cool.

You're right about headlines. The one I linked to at the Post is "The iMac Dazzles, but hold That Purchase."

Now, if you read the article you'll find that he like the computer a lot but suggests that one should wait until their favorite apps are available in Universal form before buying this computer. Good advice, and a good review.

But yes, if one reads that headline they may think something's wrong with the iMac and not read more than that.

The problem is that writers write articles and (at least at newspapers) it's their editor who writes the headline. And they're trying to attract the most eyes to the article...not write the most balanced headline. It's because of headlines like those that people might say the Post gives negative reviews. If you read them it's not true at all which is why I wanted to point that out.

Subject: uh - if you're so sure - let's trade

Hi - I'm a long time PC user but have had lots of experience working on macs for my past jobs - now as an entrepreneur I've been running my business on PC - I jumped to the new imac for home and was so happy and so impressed with it until I plugged it in and started to try to work.

The first problem was the mouse would freeze every 30-40 minutes and I'd have to unplug and replug it to keep working. Then later I couldn't type - the keyboard would just freeze, then I realized I had a problem.

I took it into Tekserve here in Manhattan - they were able to recreate the error and they took it in to repair for a week. I picked it up - took it home and plugged it in only to have the same problems happen again. They said they replaced the motherboard but I guess they didn't check for the problem before having pick it up again.

So I took it back to them again - but this time they couldn't replicate the problem! They said they would take it in but that if they couldn't find the problem it was going to cost me 130$ - I took the mac home and decided to really document every single instance of this problem.

Since last week this imac has failed 17 times to the point where I am forced to remove the usb cable and plug it back in - and still EVEN now while typing this problem there have been SEVERAL times where the blinking line just freezes and the spinning color wheel comes out... pauses and then spits out the rest of the the last word that I was typing. Which by the way was "Sucks"!

Very unhappy PC user stuck with a crap mac.

Forgive me oh great dark lord of PC's.

Have you tried going to the actual Apple store? I think it's kind of odd to give up without ever trying the easiest answer.
