but is still more productive because it handles more calculations per clock cycle
I'm no processor geek. I have a basic understanding of the terminology and how things work so correct me if I'm wrong, but wasn't this one of the advantages that the PPC had over Intel chips? Does this mean Intel is moving toward shorter pipes? Are we talking more instructions per clock cycle or what? What does "calculations" mean in this context?
With most processors, especially the Intel/AMD processors, "instructions per cycle" is not a useful number. These processors have both simple instructions (add register number 3 to register number 6) and complex instructions (add register number 3 to the number whose address is in register number 6). A PowerPC has the simple instructions, but not the complex ones. Instead it would need three instructions "load the number whose address is in register number 6, and move it to register 7", "add register 3 to register 7", "store register 7 to the location whose address is in register 6". But the Intel processor doesn't magically do three times as much work. Instead, it splits the complex instruction into three so-called "macro-ops", and does exactly the same work. So in this case, the PowerPC would execute three times as many instructions per cycle (3 instead of 1), but because it doesn't do more actual work, that is pointless. Instead you would count the number of operations, and they are more or less the same.
Intel is indeed moving towards shorter pipelines. They have done that already with the Core Duo chips. Longer pipelines have the advantage that each pipeline step is a bit faster, so you can get higher clockspeed. Shorter pipelines have the advantage that they take much less energy (very important; at some point your chips just melt), they are much faster handling branches, and they are just much much easier to design. Pentium 4 needed absolutely heroic efforts to produce it, and would have needed twice the heroics to improve it. Instead, the Core Duo has a much simpler design, that is just as powerful, and because it was so simple, Core 2 Duo could improve it.
And Core 2 Duo can now execute up to four "micro-ops" per cycle, same as the G5, compared to three for Core Duo, Pentium 4 and G4. It also has some clever features that reduce the number of micro-ops needed up to 10 percent, and some other improvements.

From now on, companies hoping to receive early access to Google's most up-to-date software will need approval of their plans.
Emphasis on the important bit for those who didn't bother to actually read the article. If you want to wait a bit, you can get the code and do whatever you want. Well that's my reading of it anyway, but please, don't let get in the way of giving the new enemy number one a good kicking.

I've owned 4 macs.
First a G3 iBook, then a G4 AluBook, then an eMac and now I'm on a G4 iBook.
NEVER had a problem with any of the machines. They have been great. Just to let you know it isn't all bad. I also pay for .mac and have done for 2 years now. I'm happy with it and yes I get spam but the filter is very good and its hardly an issue for me.
If you haven't been reading the comments, it would appear MOST people are complaining about the more recent models. I would agree with most that the Powermac G5's have had serious issues and now recent macbook's... Apple needs to do one of the following ... Higher Quality Assurance testing OR better support cause right now they're missing both.

Yes Brandon they received them in store today. My buddy was able to grab two from the local store that did not generate any PINs so I will be getting mine Thursday morning now. Radio Shack is also giving $20 Gift Cards to use towards accessories at the time of purchase in this area.
Ugh! Lucky!! I think I'm going to just keep calling my local radioshacks and head to one at least an hour before they open on Thursday!

Some called them 'the coalition of the billing' because so many members were paid off in some way.
For the Brits, that would be 'the coalition of the shilling'. :p

*iChat Phone - Call numbers through iChat as part of .Mac... I guess you could make a conference with a combination of multiple phone numbers/iChatters.
*Maps - A new application designed to compete with Google Earth, but of course be much, much snazzier. Apparently, the next MBP would include a GPS chip so that you could see a "You Are Here" on the map.
I am hoping the iPhone has BT and GPS, and links to Maps on your Mac! :eek:

Haha... no.
History has shown that having a product out sooner... doesn't mean you win the market. (Sega Dreamcast?) Sony will still kick due to the deluge of developers producing for the PS3. More software == more sales. In addition, the PS3 is completely backwards compatible (which is huge).
Nintendo will live as long as the 8 bit gen kids still are around. The Wii also promises me to play any old Nintendo game via some sort of download... It's cheap... Sign me up.
This is so right. Time and time again in the console wars, the first to market did not win in the end. It's ALWAYS been the system with the best game selection.
3rd Gen:
First to Market: Sega
Best Game Selection: Nintendo
Winner: Nintendo
4th Gen:
First to Market: TurboGraphics 16
Best Game Selection: SuperNintendo/SegaGensis (tie)
Winner: SuperNintendo/SegaGensis (tie)
5th Gen:
First to Market: Atari Jaguar
Best Game Selection: Sony Playstation
Winner: Sony Playstation
6th Gen:

Best Game Selection: Sony PS2
Winner: Sony PS2
The same could be said for advanced hardware; the winners in the game consoles were always the systems with the best game selections, not the ones that were first to market NOR the ones that had the best hardware.
Of course, this has gotten WAY off topic now ;)
(But I must say I'm going to preorder a Wii for sure!)

Gruber is rarely accurate in his conclusions, and this time is no exception.
None of what is happening smacks of being a "bait-and-switch" as he claims. That would've required extremely clever pre-planning years ago on the part of Google.
Instead, it's got all the hallmarks of too little pre-planning.
Anyone with experience dealing with large projects can see that Rubin has belatedly come to realize that things were getting out of control. Now he is goofing up trying to take full control himself instead of doing the smart thing and first getting a consensus from the OHA members.
I don't think it's about planning. After all, how much "planning" do you need to do if your philosophy behind the product is basically " open it up so everyone can contribute and see where it goes"? The point most here are making is that the age-old "open" vs. "closed" ecosystem argument, which has repeatedly been used to criticize Apple over many years, is now looking more and more as if Apple was right all along. In this case what you call "lack of planning," I call lack of much thought at all. I for one don't have much faith in most things accomplished by committee, and that is the basic flaw in most "open" systems.
The "bait and switch" reference applies in that many of those who jumped on the Android bandwagon now find they don't have nearly as much control as they thought they would, as evidenced by the complaints from that community.

I dont see much change really, the 1.66GHz merom chip will find its way into the mini (they'll scrap the solo model).
The 1.83 & 2.00GHz for iMacs (if they use merom) and MacBooks and the 2.16 and 2.33 for the 15 & 17 MBPs respectively. Its that simple.

To be fair, every smartphone on the market is an iPhone clone and every tablet an iPad clone, so it is all related to Apple in that way.
Complete BS "iphone" lookalikes date back to ebfore the iphone was anounced. So either some companys have people who can predict the future, or the design and tech behind the iphone was aused BEFORe it was released and apple just changed excisting designs.
Ipad is basicly a large smartphone.

But in the case of the Sb quad core the figure seems to be in excess of 50%, not 20%
CPU isnt the only component drawing power. AMD 6750M has higher TDP compared to 330M as well
I have already mentioned that the 40w difference measured was when it was running cinebench which does not tax the gpu at all. Gpu tdp should not be a big factor.

I think it was not a bug, nut data waiting to be sent to Apple for profit generating purposes.
But if Apple has been using this acquired data, why on earth is it allowing Google and others to eat away at its mobile & tablet marketshare? Why collect data if it isn't relevant to you business.

I'm disappointed the Bugatti Veyron is standard only
Doesnt bother me one bit, i dont like them much. Their handling always seems a bit.... "off" but i can't put my finger on it.
I probably wont even buy one, so i dont care about much of anything regarding the Bugatti.

Sure, it may be more expensive than a custom-built Intel machine, but it will run OS X like a charm, and that's ultimately the most important factor in my computer purchase. But access to Windows games and Mac OS X, that's a dream come true for this mac fanatic. I'm just keeping my fingers crossed that virtualization makes big enough strides that I never have to leave OS X to play Windows-based games.
my thoughts exactly... MacBook Pro in two weeks :D

That would be a good lineup: two Minis, two iMacs, two Macs, two MacPros. Perhaps then the spread from $1499 for a base model conroe Mac to a $3299 or even $3599 for a premo dual-woodcrest 3GHz MacPro would seem plausible? I really like having a Mac desktop option before stepping up to the MacPro (with a smaller format). Right now the iMac is your only option in a certain range.
I agree with another poster too, having both models silent would be most excellent!
This sounds to me like a redux of the Performa/Quadra/LC disaster of the late 90s...I am glad Apple has learned from its mistakes, so it does NOT stretch its production line to a plethora of unnecessary models anymore...
A cheapo MacPro model is more than enough to fill any gaps between the iMac and the Pro line...nothing else.

.... Introduction of world's first commercial 8-core system.
Not quite the first. Sun has been shipping a commercial 8-core systems for about a year now. The T2000 has all 8 cores on one chip but each core also does four-way hyper threading so they claim 32 hardware threads. The price for an 8-core T1000 is about $8K. A system with 8 cores and 8GB RAM burns about 250W
Of course it does not run OS X but Gnome on Solaris has a very OS X -like "feel" to it.
It's a lot like a Mac Pro because Sun like Apple builds both the hardware and the OS and the machine ships with many of the same applications Both are unix based with a pretty point and click window system on top. Sun is also tranitioning to X86 but they are going much slower. So far only Sun's low-end machines have moved to AMD's Operon. All the high end stuff is still SPARC.
