The second coming of Intel's Core Duo

Coming soon to a PC store near you: Core Duo, the sequel.

Intel has decided to borrow the sequential naming scheme it used for its famous Pentium brand and apply it to the new Core line of chips, the company is expected to announce Sunday. Earlier this year, Intel released the Core Duo processor, and in a few months it will unveil Core 2 Duo processors. The Core 2 Duo name will be used for desktop chips based on the Conroe chip, as well as for notebook chips based on the Merom chip. Merom processors consume less power than Conroe chips, but they're otherwise very similar.

branding legacy, as it will be
the second Core Duo product.

Each Core 2 Duo chip will also have a model number that will indicate how much power it consumes and its relative performance, said Intel spokesman Bill Kircos. The Conroe processors will fall into either the 4000 series or 6000 series, while Merom processors will use either the 5000 series or 7000 series numbers, he said.

Conveniently, the Conroe numbers match up well with the model numbers used by Advanced Micro Devices on its current generation of dual-core Athlon 64 X2 desktop processors. AMD's highest-rated Athlon 64 X2 processor as of Friday is the X2 4800+. Kircos declined to comment on whether Intel chose the new scheme to line up with AMD's model numbers.

Each one of Intel's model numbers will be preceded by a letter that indicates how much power the chip consumes at its peak. This is the first time Intel has incorporated power consumption into its model numbers. For example, the Core 2 Duo E6800 processor would represent a dual-core Core-architecture processor that consumes between 55 watts and 75 watts of power, which Intel considers the standard desktop PC category. The hypothetical Core 2 Duo T5400 would represent a dual-core Core chip that consumes between 25 watts and 55 watts of power, a range Intel thinks is appropriate for most notebooks and some desktops.

Over the last year Intel has put increasing emphasis on its platform brands, such as Centrino for notebooks, Viiv for entertainment PCs and vPro for business PCs. But the company will continue to emphasize the individual processor brands, Kircos said. "I think you'll see equal amounts of marketing around the processor and platform brands," he said.

The end appears nigh for the Pentium brand, which has carried Intel for 13 years. Intel is expected to rapidly shift its factories to cranking out Core processors by the end of the year.

Last week, Intel announced plans to bring out the Conroe and Merom chips in July and August, respectively, which is earlier than expected.

First model number with power?
by aabcdefghij987654321 May 7, 2006 9:41 PM PDT
Not true. The current line of Core Duos model numbers include
power consumption. The T1xxx is single core full power, T2xxx is
dual core full power, L2xxx is dual core low power, U1xxx is single
core ultra-low power.

So it's probably safe to assume that we'll see a similar arrangement,
T for full power, L for low power, U for ultra-low-power. (And
probably D as the prefix for desktop parts, X for the 'Extreme'
parts.)

marketing is everything - part 2
by anarchy1999 May 8, 2006 2:22 PM PDT
when amd released the 1st batch of dual core athlon, sun and ibm were laughing and getting drunk at the cheap stunt from amd motto - amd64. marketing is everything regardless what crap you sell. that motto hasn't changed throughout all the new chip releases from amd, and when quad core gets released, amd will change their motto to amd128. yep, you can't fix stupid! and there are lot's of people out there that have no idea what they are getting for an expensive toy.
i live in marketing and i know how low companies will go to attract share holders.

to this day i still don't know why apple chose intel over amd. both chip companies were kissing apple butt really good and throwing money in r&d transitional phase. but steve jobs chose intel. if i knew the reason for it, most likely i'll be sued for insider trading. so i'll keep that vault closed.

i don't know why intel is not defending itself from amd marketing bashing. hello intel wake up! if amd would have picked on apple for using intel chips, steve jobs would have liquidated amd in 5 working days so he can play golf on saturday and sunday.

marketing bashing is normal in the market. everybody does it and it has been going on for at least 15 years. as long as amd doesn't claim that their chips are used in the international space station, or stealth bombers, amd is safe. on the mean time they can bend and break the rules any way they want as long as they are not breaking the law.

why do you think amd is suing intel from delaware? it's just a legal manipulation because amd is buying sympathy. delaware feels sympathetic to the little guy. amd reminds me of the movie - the good son. if they would sue intel in california, the whole case would be thrown out of court due to intellectual retardation. everybody in the it industry knows that. the corporate cooperation in the case of amd vs intel, has been very friendly because they have nothing to hide. but amd has too much money to spend. it looks like amd is out of prescription medication and hasn't gone for a refill.

Performance of Core Duo vs Centrino
by LorinT May 9, 2006 12:29 AM PDT
I recently got a new Sony laptop with a Core Duo processor, and since it runs at the same 1.8 GHz clock speed as my other Dell with a Centrino, I decided to do some performance testing. From the results, it looks like the way programs are written will make a huge difference between whether or not we see a performance gain out of the new Duo line:

Word on the street is that they will indeed be compatible and that only a BIOS update will be required.
