I thought part of the point of penryn was to get lower power using chips to increase battery life for the laptops. Why then are each of the MBP replacements all 35W TDP, which is the same as the current chips?
I understand they are higher clocked, but the whole Hi-k thing was supposed to solve world hunger and bring peace on earth, so I'm surprised at the same TDP.
iWonder if a four core mac book pro could be a big fat surprise for all of us at wwdc 2008.
No. Don't expect four cores until Nehalem (new microarchitecture to replace "Core"). Four cores with "Core" microarchitecture still requires too much power and generates too much heat for the MacBook Pro form-factor.

The speed gain is pretty minor but I suppose it's getting more and more difficult to squeeze any more power without sacrificing battery life.

Whilst, on the whole, the speed increase will be quite minimal, some applications will see a very significant (can be over 100%) boost if they can make use of the new SSE4 instructions. Also, fixed-point divides should be twice as fast, the increased LII cache should really help some apps, and virtualisation overhead is reduced.

Yes, they are drop-in replacements. No, there will be no change in the RAM used, as it's the motherboard chipset northbridge that provides the RAM bus, not the CPU. The northbridge will remain the same with the CPU upgrade to Penryn.

Unfortunately, you are talking nonsense. For one thing, the RAM currently being used is 667 DDR2, not 800, and as I said above, the CPU isn't the thing that provides the RAM bus so there is no opportunity here for increasing RAM speed. 667 DDR2 is the maximum speed that the northbridge from Santa Rosa supports. You have been confused by the fact that the the introduction of the desktop Penryn was accompanied by an update to the desktop motherboard chipset, and it is this that supports DDR3.

It's even more confusing than that! The orginal "Core Duo" chips did not use the "Core" microarchitecture. The "Core 2" chips are therefore revision one of the Core microarchitecture. The PR department at Intel really needs to get its act together!

I was surprised also, although we knew this a long time before today. Whilst the "TDP" (the figure the engineers have to work to when designing the CPU cooling system) has stayed the same, the hope is that average power consumption will be (much?) lower due to better energy-management in the chip - i.e. at low and normal/medium CPU loads, the power consumption should be lower, whilst it's under max loading that the Merom and Penryn heat generation is the same.

This absolutely puzzles me. Shouldn't it have a lower TDP, use less power and generate less heat? Heck the clock speeds are very similar to the last batch of 65nm Meroms. I hope someone can answer this question.
Frankly I don't know how they'll be able to release a subnotebook as rumored if Penryn chips don't have a lower TDP. How will they be able to cool it? I've a MBP with a core 2 duo and unless the Penryn generate *significantly* less heat, I don't know how they can make a thinner laptop.

To date, Apple haven't used any of Intel's ULV (ultra-low voltage), or L (low voltage) parts. These have a lower clock-speed and much lower TDP (e.g. the U7600: 1.2 GHz, 10 W; L7500: 1.6 GHz, 17 W). The U7600 and L7500 are Merom parts, presumably there will be Penryn equivalents when the time comes.
Edit: All I could find after a quick search implied that ULV and LV Penryn parts won't be coming out until later in 2008. So if we get an ultra-portable in January, it'll be either be Merom based or won't really be an ultra-portable (and with a rumoured 13.3" widescreen, that definition already seems tenuous).
I am so torn about my next Mac upgrade ... after years of using Mac Towers for digital media work (and I still have a Dual G5), would the new (expected) Penryn X 24" iMac top of the line be good enough? I could attach my 23" Cinema to one and have a 24" and a 23" screen area, drool, (and disconnect the second screen when more Graphics card power is required) ... ... if they up the graphics card it it too ... Oh torment! What to do?
It wouldn't be good enough compared to a Mac Pro. Never will.

Penryn is paired with a new chipset, Bearlake, which includes an increase in bus speed (connection to the northbridge, etc.) for certain models to 1333 MT/s and will include support for DDR3 SDRAM; Intel believes that DDR3 is particularly useful in the power- and heat-constrained environments within mobile equipment.

Yes, you are correct, the current MB and MB Pro's are based on the Santa Rosa chipset, which operates the processor on a front side bus of 800 MHz, but the chipset runs the RAM at 667 MHz. I have 800 MHz DDR 2 RAM in my notebook and it runs fine, but at 667 MHz of course. I originally bought 800 MHz RAM because, I hoped it would work in the next generation of laptops Apple released, and thus, would prevent me from having to buy RAM upgrades twice. However, I ended up getting screwed, because Penryn will use DDR3 at 800MHz, and thus my RAM will not work in the new machines.
Whilst, on the whole, the speed increase will be quite minimal, some applications will see a very significant (can be over 100%) boost if they can make use of the new SSE4 instructions.

Thank goodness for some common sense in this thread. The suggestion that these chips are lackluster is really pretty absurd. As to wishing for the good old days of infrequent CPU updates, well, those who long for that era can return to it while the rest of us enjoy the dynamic present. I, for one, have been pleasantly impressed by the modest and relatively frequent incremental increases in the portable line. Meanwhile, the folks who have waited to see similar increases in the Mac Pro line would no doubt welcome more frequent updates. As to the difficulty (for consumers) in differentiating between the various chips, all I can say is — hey — that comes with the territory. In fact, Intel's line (and Apple's) is refreshingly streamlined.
I admit that it's generous and considerate to express a concern for the benighted consumer, but when it comes to fairly high dollar items like computers, consumers owe it to themselves to do some research in advance of a purchase.

Bearlake is a desktop chipset. The reference to mobile equipment is therefore erroneous.

Ah, I see. Well, the first Penryn MacBooks will still have Santa-Rosa-based motherboard chipsets, so the RAM bus will still be 667 and you can still use your 800 MHz RAM.
...is a couple of Penryns crammed into the rumored ultramobile MacBook, swathed in aluminum. It would be the world's first combination laptop and toasted-sandwich maker. Yummm.
apple not only needs an update on the CPU used in macbook pro and mac pro...they both need a redesign- it has been so long since the last redesign of the case
i agree - i reckon a quad-core macbook pro at the wwdc would be a nice fat surpize
Intel Corp. plans to formally introduce its Penryn family of next-generation mobile processors in early January, paving the way for significant upgrades to Apple Inc.'s notebook and iMac consumer desktop lines shortly thereafter.
[...]
Higher performance versions at 2.5GHz and 2.6GHz will each pack 6MB of Level 2 cache and sell for $316 and $530.
Each of the aforementioned Core 2 Duo models will sport a thermal design power (TDP) of 35 watts, while a 2.8GHz Core 2 Extreme ($851), also with 6MB of Level 2 cache, will feature a TDP of 44 watts.
Apple is likely to adopt one of the Core 2 Duo Penryn chips for its upcoming sub-notebook, while using the remainder of the chip family to boost the specs of its MacBook Pro and iMac desktop line.
It would be quite a disappointment if Apple were not to offer any Penryn quad-core desktop CPU based iMac next month.
Intel doesn't plan to limit itself to Penryn dual-core mobile chips and Apple competitors, the HP, Dell and others, plan to use Penryn quad-core desktop CPUs in their upcoming desktop models.
The only reason the iMac is so slim, the only reason it is currently using mobile Merom based chips, is that Apple wanted to save money with massive orders of a single model of chip to be used in both mobile and desktop computers. With the availability of quad-core desktop chips, 6 months earlier than any quad-core mobile chip, Apple will no longer be able to claim that mobile processors are equivalent to their desktop siblings.
Apple customers deserve the best computers that money can buy and that includes iMacs with quad-core desktop CPUs, just like desktop models offered by HP and Dell.
The other issue is competitive pricing. At present, a MacBook with a 13 inch screen and a 120 GB hard drive is $550 more expensive than an HP mobile computer with a 15 inch screen and a 160 GB hard drive. Personally speaking, I can't justify paying the $550 difference for a lower spec computer.
Is there a link between overpriced computers and the billion dollar bonus paid to Steve Jobs and his pet Vice-presidents over the last 2 years? You have to wonder. Do I want to support with my money further customer and shareholder abuse?
It would be quite a disappointment if Apple were not to offer any Penryn quad-core desktop CPU based iMac next month.
What are you basing that disappointment on? On the theory that 4 should be better than 2? There are only certain circumstances that 4 cores will be used. Most of the time they would only be used at a fraction of their true potential.
Its like having an engine designed for formula one racing in a family car.

Which HP are you looking at? I see one at $450 with Intel Pentium Duo, which is not the same at all as Core Duo processor. What I see at $599 is not speced similarly to the Mac Book at all. Once you do add the same spec as the Mac Book it costs $1461.

I was looking at the December flyer from Staples. The price difference stems mostly from the processor used. Both Toshiba and HP use the Intel Core 2 Duo T5250 (@1,5 GHz, according to a quick Google search) for a mobile computer on sale for $799.96, whereas the $1349.96 MacBook or the $1499.96 black MacBook both use the more powerfull Intel Core 2 Duo T7500 (@ 2,2 GHz, according to a quick Google search). All prices are Canadian dollars, but Staples is also in the US and the UK, so you can compare prices at your local store.
While I feel better knowing that Apple uses more powerfull mobile CPUs, I don't believe that most buyers do a Google search to find the speed difference of Intel model numbers. As all computers have a webcam and Intel GMA X3100 graphic chip, they look the same to the casual buyer. And Toshiba and HP come with a 15 inch screen, a bigger hard drive and $550 cheaper than a white MacBook. That's enough to close the sale in most cases.
Now, concerning quad-core iMacs. Do you believe for an instant that HP, Dell, etc. will find it difficult to sell desktop computers with quad-core CPUs once Intel manufactures Penryn quad-core CPUs? Computer buyers look forward at the next 6 years, not backward at the last 2 years, when deciding to buy a computer. And Penryn quad-core desktop CPUs are just around the corner.

Intel's system for naming their chip products is the pinnacle of obfuscation. It is very difficult to tell exactly what you're buying. Probably the easiest way is to look it up in the system profile of the machine in question. It will tell you the clock speed of the processor. That's what I do when looking at vista machines. Many people may not be aware of this and just buy what's put in front of them by unscrupulous sales personnel.
As for quad core iMacs, I think that won't happen until Intel release *mobile* quad core chips which IIRC isn't until, later this year. I don't think that desktop cpus can be put into iMacs due to the thinness of the enclosure.
What are you basing that disappointment on? On the theory that 4 should be better than 2? There are only certain circumstances that 4 cores will be used. Most of the time they would only be used at a fraction of their true potential.
More and more this isn't true. Software is getting on the multi-threading bandwagon, and operating systems are leading the way. Whether it is QuickTime, OpenGL, CoreAudio, CoreAnimation, or the multitude of OS house keeping processes (Windows has its equivalents) your other cores are becoming more and more well utilized all the time. And if you don't need the extra ones, the latest chips can idle unneeded cores so they cost you very little and free up shared cache resources. Soon we're going to have desktops where 8 cores are commonplace, and 16+ hardware threads are available.
Maybe it's just me, but Intel upgrades are so common place now that it's hard to get excited.
The speed gain is pretty minor but I suppose it's getting more and more difficult to squeeze any more power without sacrificing battery life.
The bigger issue is consumer confusion. How the heck is Joe Consumer going to keep up with which MacBook he's just purchased. Too many cache, FSB and clock speeds to remember. He may very well be misguided in buying an older generation from a retailer still holding on to older stock.
I realize it's about keeping up with the competition, but I really think it's more to Intel's benefit than Apple's.
One's 65 nm, the other is 45 nm, simple, done...besides with Apple, it's not like you have to contend with FSB and cache, you're given what Apple offers, it's not like you can go on newegg and build a Mac from scratch like you can a PC. When Apple offers an xMac, it might mean something.
The biggest advantage will be power consumption and a faster FSB, but I doubt Apple jumps to update soon anyhow.
If the next gen iMac don't do something about their screens, I won't be buying one soon. They need to 1, give photographers and other graphics people a choice of glossy or matte, because many of us hate the glossy screens, but that can be lived with, if Apple must drive their product by form over function.
What is unacceptable is that the current 24 screens tend to be a good f-stop of difference in brightness from one side to the other, and the 20" screens are not even 8 bit, but are 6 bit and tend to be washed out at the bottom and fairly useless for hardware calibration and color accuracy. The 24" will calibrate fine except for the brightness unevenness. This is a big step down from the white imacs. I'm willing to pay a hundred or 2 more to have a top flight screen like they used to have in the Intel iMacs. Just my opinion.

Which HP are you looking at? I see one at $450 with Intel Pentium Duo, which is not the same at all as Core Duo processor. What I see at $599 is not speced similarly to the Mac Book at all. Once you do add the same spec as the Mac Book it costs $1461.
What are you basing that disappointment on? On the theory that 4 should be better than 2? There are only certain circumstances that 4 cores will be used. Most of the time they would only be used at a fraction of their true potential.

I was looking at the December flyer from Staples. The price difference stems mostly from the processor used. Both Toshiba and HP use the Intel Core 2 Duo T5250 (@1,5 GHz, according to a quick Google search) for a mobile computer on sale for $799.96, whereas the $1349.96 MacBook or the $1499.96 black MacBook both use the more powerfull Intel Core 2 Duo T7500 (@ 2,2 GHz, according to a quick Google search). All prices are Canadian dollars, but Staples is also in the US and the UK, so you can compare prices at your local store.
While I feel better knowing that Apple uses more powerfull mobile CPUs, I don't believe that most buyers do a Google search to find the speed difference of Intel model numbers. As all computers have a webcam and Intel GMA X3100 graphic chip, they look the same to the casual buyer. And Toshiba and HP come with a 15 inch screen, a bigger hard drive and $550 cheaper than a white MacBook. That's enough to close the sale in most cases.
Now, concerning quad-core iMacs. Do you believe for an instant that HP, Dell, etc. will find it difficult to sell desktop computers with quad-core CPUs once Intel manufactures Penryn quad-core CPUs? Computer buyers look forward at the next 6 years, not backward at the last 2 years, when deciding to buy a computer. And Penryn quad-core desktop CPUs are just around the corner.

Intel's system for naming their chip products is the pinnacle of obfuscation. It is very difficult to tell exactly what you're buying. Probably the easiest way is to look it up in the system profile of the machine in question. It will tell you the clock speed of the processor. That's what I do when looking at vista machines. Many people may not be aware of this and just buy what's put in front of them by unscrupulous sales personnel.
As for quad core iMacs, I think that won't happen until Intel release *mobile* quad core chips which IIRC isn't until, later this year. I don't think that desktop cpus can be put into iMacs due to the thinness of the enclosure.

More and more this isn't true. Software is getting on the multi-threading bandwagon, and operating systems are leading the way. Whether it is QuickTime, OpenGL, CoreAudio, CoreAnimation, or the multitude of OS house keeping processes (Windows has its equivalents) your other cores are becoming more and more well utilized all the time. And if you don't need the extra ones, the latest chips can idle unneeded cores so they cost you very little and free up shared cache resources. Soon we're going to have desktops where 8 cores are commonplace, and 16+ hardware threads are available.

And the scary part; someday those specs will apply to a basic handheld Newton/iPhonesque device?
This is why I wish the stupid MacPro would come out now! Debut some crazy fast laptop stuff at MacWorld. Just give us the MacPro now.
Agreed.
Maybe it's just me, but Intel upgrades are so common place now that it's hard to get excited.
The speed gain is pretty minor but I suppose it's getting more and more difficult to squeeze any more power without sacrificing battery life.
The bigger issue is consumer confusion. How the heck is Joe Consumer going to keep up with which MacBook he's just purchased. Too many cache, FSB and clock speeds to remember. He may very well be misguided in buying an older generation from a retailer still holding on to older stock.
I realize it's about keeping up with the competition, but I really think it's more to Intel's benefit than Apple's.
One's 65 nm, the other is 45 nm, simple, done...besides with Apple, it's not like you have to contend with FSB and cache, you're given what Apple offers, it's not like you can go on newegg and build a Mac from scratch like you can a PC. When Apple offers an xMac, it might mean something.
The biggest advantage will be power consumption and a faster FSB, but I doubt Apple jumps to update soon anyhow.
What is unacceptable is that the current 24 screens tend to be a good f-stop of difference in brightness from one side to the other, and the 20" screens are not even 8 bit, but are 6 bit and tend to be washed out at the bottom and fairly useless for hardware calibration and color accuracy. The 24" will calibrate fine except for the brightness unevenness. This is a big step down from the white imacs. I'm willing to pay a hundred or 2 more to have a top flight screen like they used to have in the Intel iMacs. Just my opinion.
