Do you have a reference showing that this translates to better performance in real-world application tests in a head to head competition?
Not handy, since a lot of this happened on mailing lists.
The short version is that the memory performance scales in a very sub-linear fashion as a function of the number of cores being used, whereas Opteron scalability is almost linear up to a large number of cores. The good news is that for single dual-core processors the memory performance is on par with dual-core Opterons and their in-cache performance can be better. The bad news is that this performance does not hold as you scale cores in a system. So for some applications (e.g. those that live mostly in cache) the Woodcrest processors will be mildly faster than Opterons, but for most the performance is about even in real app benchmarks.
I've seen fairly comprehensive benchmarks for both databases and scientific computing applications, both of which thoroughly exercise the memory subsystem. Even though a single Intel core theoretically has more bandwidth, the high latency means that the real bandwidth is about the same as the slower Opterons (which have real bandwidth that approaches theoretical) and the cross-sectional bandwidth of Opterons when you get up to 4 cores and higher is much higher since the scaling is almost linear with the number of cores. For Intel, I think it was the case that a bigger cache was a cheaper design choice than a truly scalable memory subsystem. As a result, they will have different competencies. Some types of floating point codes should run very well on Intel.

Ah, a mature, intelligent, well reasoned reply.
No, one that just ignores you and your inquiries because it was already clear where you were coming from..thus I feel no obligation to engage you in my thought process and your self important questioning. Has nothing to do with my maturity, and everything to do with my lack of caring about you or your opinion.

It's about consistent sales numbers, lower volatility. I'm sure bonus numbers etc. are tied to this. Just like when a company has a great quarter, they may try to push out revenue to the next quarter. Less volatile net income equals stronger stock price.
Not that this move would necessarily influence the stock significantly but same concept.

The point is no one will ever confuse this with Apple's iPhone... But what Samsung is doing now is another story.
If you look at each item that Apple takes exception with individually it seems silly, but when you put them all together in a single device it's a twin to the iPhone... An iClone.:rolleyes:
Actually, the point was that Samsung did not have a grid of icons on the F700 until after the iPhone released...so Apple did not copy Samsung. Eventually, what you say is true.

Incorrect - it's not tracking your direct location as you assert.
For instance, when you're visiting "Harry's Sex Shop and under the counter Heroin sales" it doesn't track that you're actually at that business.
Depends.
Someone could infer that info, if the cell cache says that around 2am you visited the town Harry's is in, and it's the only store open at that time.

It's not like they threatened anyone. They likely went to the organizers and said "We'd like to make a really cool announcement at your event but we'd need most of your presentation and sponsorship space to do it." SuperMeet said sure, Apple paid, and here we are. It's not like the other sponsors didn't get their money back (I'm assuming.)
The other presenters just had to toss months of planning out the window and scramble to reschedule events w/less than a weeks notice during the industry's biggest annual convention. Hopefully the members of the audience that signed up to see the original line-up will be able to make it to all the reschedule events and, on top of that, everyone going to the SuperMeet has now paid money for tickets to what is nothing more than an Apple PR event.
Dick move by Apple but all will be forgiven as long as they release the holy grail of editing on Tuesday. If they preview 'iMovie Pro' lord help them...
He is asked if he will update his editing studio's workflow to the new Final Cut, and he basically danced around the question, pleaded the 5th, and made it pretty clear that he is holding back some reservations about how the industry will adapt to the changes.
To be fair to Mark (the head of Post at Bunim/Murray) there really isn't anything he could say due to the NDA. Just because what he saw of the new FCP might not lead him to believe it would work in Bunim/Murray's current workflow doesn't mean it might not be awesome for someone else's work flow. It was a tough spot for Mark to be in and I'm not exactly sure why he even kicked off the meeting with "I was there, but don't ask me about it because I'm under NDA". He could've never even have brought it up and it wouldn't have altered the course of the conversation at all.

Oh FFS... Ok, yes, if we're being pedantic, I'll wait until I try both iOS 5 and the Playbook before deciding.
:rolleyes: I wasn't being pedantic. You were the one calling for more rational conversation. I agree. And then you curse and belittle the first reply to your post.
I think it's disingenuous to call iOS lagging compared to the Playbook OS when you know perfectly well that iOS will likely be updated around the same time as the Playbook release. It's been played out over and over again in these forums where a demo of an unreleased product is hailed as so much better than Apple's version that came out almost a year ago. Maybe it's just a pet peeve of mine.

Won't Adobe use Core Image when the Universal Binaries come out? If both Quads had the same high powered graphics card, the benchmarks may show them to be the same with Core Image tasks.
Hah! Adobe can't even be bothered to make a Cocoa-native version of Photoshop on the Mac. They won't use Core Image because it's an OS X-only technology which can't be ported to Windows without them having to (essentially) write their own framework to mimic its functionality.

if merom produces less heat.. i would think that apple will quickly update both MB and MBP so it won't be releasing anymore problematic notebooksYes your logic is impecible. But Apple does not act on logic. They are in it for the money. :D

But he then said after how well it would work on the phone, they put the tablet project on the shelf and focused on the phone as it was more important. Which means it was a tablet and no just a touch screen device in the beginning.
yes, seems it was this way:
1. tablet concept/prototype
2. use ideas from that tablet concept to create iOS/iPhone
3. continue development for tablet
Apple also realized that it is easier to market a smart phone first which than makes it easier to market a tablet build on the same OS. iOS/iPhone was never a independent development but strongly tied to the tablet development.

I'd also like to point out I've never actually gotten XP's system restore to work, I've tried about 10 times over the past 5 years. Maybe I'm the exception, but you really can't rely on it.
I've had it TRASH a machine at my home before. But I've used it successfully at work once or twice. For the disk space, though, I often turn it off. It is a complete pig, and if I'm tight at all, it's the first thing to go.

A bit pointless given that no software utilises the extra cores yet. But nice to know, I guess.
I'm still getting used to having two cores in my laptop!
No software such as, Cinema 4D, Motion, Aperture, Final Cut Pro etc

Just a few hours left, let's hope we see new MacBook Pros tomorrow, I think we'll see the new iMacs with Merom in Paris, because it's a very good announcement for consumers, and get the Pro MB's tomorrow.

Perhaps we should all get a rebate for every crappy album ever released by Universal. I really want some of the stuff that these record execs are smoking, on top law suits and strong arm tactics now they expect to get money from every iPod not because the have provided any service or contributed in anyway to the product. Rather, they just want it. Hell, who doesn't ... I would also like to get in on this deal. Please Apple/Microsoft/SanDisk I would like to get $0.50 for every unit you sell. Sign me up. I think it is time that artists really evaluated the balance of power. I think it is time that artists should reevaluate the distrubution of wealth in the recording industry. Perhaps that lost money isn't due to pirating like the execs want you to think.

yeah, what he said. Apple does not have to distinguish powermacs from servers with processor speeds. People (businesses) who need servers are not going to buy powermacs to do the job even if they are a little bit faster or cheaper; they are going to buy real rack-mounted servers.
Now you're not thinking like a competitive company that needs to continue to make money.
Sun is on the ropes and Apple now has a chance to soar in and take a lot of business from them.
How does Apple releasing an eight-way workstation prevent them from competing with Sun in the server market, again? I must have missed that part.

Apple won't put GPS in unless they can create a whole new 'Apple' interface for it.
I'm no GPS expert, but I'm not sure how they could do that with a simple candybar phone. It would need to be some sort of smartphone / pocketPC thing.

im glad i bought just the other day, itll be within the 14 day return period. i know some people have said they are able to get the restocking fee waived. any tips on this?
I'm almost tempted if they come out with a Merom update. I purchased mine yesterday so I might be in the 14 day period. But, do I really feel like setting up all my stuff all over again? for a 10% increase in speed?

The side menu in the Mail (at least in the Quicktime demo on Apple) shows Notes and To Do. Wouldn't it make sense to finally bring Address Book and iCal into Mail along with these new options?
I know that would make it very Outlook but Outlook 2003 is one of the (few) things Microsoft has managed to get right.
I just don't see the need for Address Book and iCal to exist separately from Mail if they're going to be even more integrated with Mail.
