This is interesting, BUT, from what I know, Intel announced the desktop (Conroe) Core 2 Duo proccessor on July 27, and as far as I know, no Conroe systems are shipping right now, almost a month later.
Dell has announced some Conroe systems that you can order, but as far as I know they aren't readily shipping yet.
I believe Intel has been having trouble getting the required chipsets out on time to the desktop market.
You can get the chips themselves without much trouble- the retail versions are available at Newegg for the 1.86, 2.13, 2.66, and 2.93 Extreme Core 2 Duo chips, with the sole out of stock chip being the 2.4GHz chip, with an estimated time of arrival being Sept. 1st at 2:30PM.

nVidia 320M si about 20W, so they can use 17W processors on 11,6" and 25W processors on 13", with an increased battery life on both models.

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.

Careful, some trolls will insist that your opinion is only relevant to your narrow world view and that you need itemized spreadsheets to prove that you know what you're talking about.The positive is that all the other mentioned apps are Apple capable :)

That's not being exclusionist.
Rape and paedophilia are bad no matter who does them.
It would be exclusionist to say:
"Rape and pedophilia are bad for everyone except for Catholics"
Oh wait...
Do you realize how incredibly rare paedophilia is? Also the Media is stupid and uses the wrong words intentionally. Truth, outright slanderous lies, what's the difference if it sells copies eh?

Naw, memory too. There's probably a lot I left out, it was just a quick list off the top of my head.
64bit will just expand memory access it does not have anything to do with being multiprocessor aware.

Since the WWDC is focused on developers, wouldn't it make the most sense for Apple to do all of the chip transition announcements plus the Leopard preview at WWDC and wait until MW SanFran or hold a special event for the video iPod/iTunes movie announcements? After all, developers want to know what to expect in the forthcoming OS and what the processing abilities for the full range of hardware will be so they can devise applications to fully exploit the specs on the OS and the various hardware configs. iPod and iTunes announcements may be neat, but they would seem to be less relevant to the WWDC audience.

Thank you!
I wanted to write every point you just made .. i'm just glad other people are capable of rational thought. It seems as though these people expect that if they don't like something then no one will, as though their uses are the most important and anyone else who disagree's doesn't use their computer for 'real work'.
Every one of the new features in Lion i am really excited about, the integration of server allows me to use my old Mac as a media server, Versions is a killer feature, as a developer i've been using local repo's forever. FDE is epic, anyone who cares about data security and used FileVault understands how much of a pain it is. I use my notebook and plug it into a large screen when i'm at a desk, i'd like fullscreen apps when i'm in notebook mode thanks. I could go on and on ...
I'm running Lion, and personally I hate Mission Control. There is no way to turn it off (there really should be). It's such a pain trying to select the other windows when they are grouped together. Horrendous implementation.
Full screen apps...If I wanted to run and see only one app at a time....I'd use my iPad!! Fullscreen apps are just gimmicky.
Resume...crappy, especially if you're not on a $$$$ SSD. It loads every program that you were using before reboot, good idea, but it just takes forever to use my computer after rebooting since it's loading 10+ apps!

Of course, the problem with waiting until Paris for consumer upgrades like MacBook is that Apple will entirely miss the educational buying season, losing one of the largest markets for its consumer products...
apples education buying season is now.... in fact, theyve already had a 33K notebook order from one school that i read on.

Do you get a prize car for finishing a series in Aspec races with all gold? Like I just need to finish one more race, but I can't find a used car to get into it. It's the first series of races, beginner I am assuming.
Some of them do but not sure do all of them. I've got several nice rides from those series but they are mainly from higher level series.

If they're playing this close to the chest, as was rumored last week, then I'm likely to believe that people are being lead on about when the supply chain will ramp up.
Also, consider that the iPhone 4 is old at this point and still selling well compared to brand new Android phones. Hardware doesn't mean much to the consumer, it's the experience.

It would be ridiculous if it came with just 512 mb's of ram...
Steve Jobs-"The New Octa-Core Mac Pro with 512 mb's of ram" It just doesn't fit...
I honestly think it'll have 1GB standard- they can save money by not having to bother with FB-DIMM 512s. its cheaper to just get 1 and 2 gig increments.

Wow. You'd think a FCP Users group would be able to track down a halfway decent graphic artist to make their banner graphic...
At least the one on their website looks fine (yet still ugly), the one on MacRumors looks resized and the pixels got messed up... :confused:

Kind of odd/funny how we seem to be going backwards in processor speeds. Instead of 3.6 GHz Pentiums, we are looking at 2.x GHz Intel Cores. It would be interesting to see how well a single Core processor matches up to PowerPC, or a Pentium, or AMD.
It just means that Intel has finally publicly recognized the validity of the MHz Myth.
Raw clock speed is meaningless. You can get better performance at a slower clock speed if you can increase parallelism. This includes features like superscalar architecture (where multiple instructions are executed per clock), deep pipelining, hyperthreading, SIMD instructions, and multi-core chips.
However, I am finding one of my predicitions finally happen...it appears that a ceiling has been currently met on how fast the current line of processors can go, and now we are relying on multiple cores/processors to distribute work, instead of relying on just one fast chip.
That's a part of the equation, but not all of it.
Higher clock speeds are possible, but it's not worth the effort. Pumping up the clock speed creates serious problems in terms of power consumption and heat dissipation. Leaving the clock speed lower, but increasing parallelism will also boost performance, and keeps the power curve down at manageable levels.
It's worth noting that Intel has shipped P4-series chips at 3.4GHz. But the new chips (Woodcrest and Conroe) aren't being sold at speeds above 3GHz.
So when will we start seeing 8 chips in a computer? Perhaps this will become the new measurement...not processor speeds, but the number of processors (or cores).
Pay attention. The answer is "sooner than you think".
There have already been technology briefings from Intel that talk about 4-core chips in early and 32-core chips by 2010. Similar offerings are expected from AMD.
And the Xeon-MP series processors (which will, of course, eventually get all this tech) are designed with 8-way SMP in mind. A theoretical Xeon-MP based on this 32-core tech would produce a system with 256 cores. Of course, it is doubtful that anything other than a large server would be able to take proper advantage of this, so I wouldn't ever expect to find one on a desktop.
(FWIW, Intel is looking to Sun as a rival here. Sun's latest chip - the UltraSPARC T1 (http://www.sun.com/processors/UltraSPARC-T1/) - currently ships in an 8-core configuration, with each core capable of running four threads at a time, and only consuming 72W of power. Even at 1.2GHz - the top speed they're currently shipping at - this makes for a very nice server.)

I have enough skill to win the faster races, i just have more fun with a "real" car instead of something with neck-snapping acceleration and tires that stick to the road if you take a hair-pin at 200mph.
I have a lot more fun driving cars that anyone can afford.
are you rich then? :p
i only hope that GT5 is more realistic then simulated this time..

I am a new Mac owner. I just bought my new 20 " iMac and I am learing aout the upcomming conference and possible new product releases. I
Would appreciate any thoughts on my question.
I am considering returning the new 20" I just bought in the 14 day period and taking the 10% hit and waitning to see if the iMac gets updated and I will repurchase. What is the likelyhood that the version I have will be updated. I would be bummed if I just bought it and I am at the end of a cycle. The $160 fee would actuallly be worth it to me to get thte latest. I would have to return it prior to the conference to stay within the 14 days but i may not want to loose out on lthe chance to get the latest.
Any thoughts on this 20 " model be increased with a new processor??
Thanks,
New Mac owner.....

The iPad two does have some shortcomings, few of which are worth going to to here. However, the OS of these devices IS crucial and we are beginning to see iOS creaking slightly. In terms of looks and notifications, for me, Apple is lagging. I like how the Playbook looks and potentially, should operate. Will I make a snap judgement? No. I'll try the damn thing first before making a judgement.
Why are you comparing the Playbook that is coming out this summer to iOS 4? Chances are it will be competing with iOS 5. If you want to be fair and all.

1) Who says the people who actually make the music would get any of this money in the first place?
My bet is that artist's contracts only pay out on music sales, not hardware royalties. Thus the cdrom tax and ipod royalties are profits they don't have to share with artists despite their pious rhetoric about how they need these revenues because piracy hurts recording artists.

I hope that number keeps rising; we need competition to not let Apple rest on it's laurels.
First they need to make a product worthy of rising. A sub par product and user experience will not push Apple.
At any rate, clearly Apple is not resting on laurels with the rest of computing industry as far back as they are in quality, price, experience and their available software ecosystems.

You obviously missed the point that they do not track anything. It's just a log file on your iphone, it stays with your iphone. I GOT even more news!! I FOUND a file on the iphone that stores text messages. YES PEOPLE text messages. I can read your text messages from this file if I have your phone!! Oh ya, I know you can launch the SMS app, but WHY WOULD APPLE NEED TO STORE TEXT MESSAGES ON MY DEVICE?!?! I'm suing!!
Just like web caching, storing text messages is part of the function of the messaging app. It serves a purpose of giving YOU a history.
And guess what... you can clear it. ;)
