More performance, more options: here's "Merom"
Today Intel is
expected to officially launch
the Core 2 Duo processor for mobile platforms. Based on the
core, Core 2 Duo is arguably the industry's most anticipated mobile processor launch of this year. Judging from performance comparisons of its desktop counterpart,
, Core 2 Duo should deliver some very impressive performance benchmarks in notebooks, which will also be announced this week. While Intel had a
launch party for Core 2 Duo earlier last month
, today marks the official day when products with Core 2 Duo processors become available. Expect major manufacturers such as
Dell, Lenovo, Sony and others to release notebooks based on the new platform
remain nearly identical
with the majority of Core 2 Duo processors coming with 4MB of L2 cache and running on a 667MHz front-side bus. Even low-voltage versions of Core 2 Duo such as the L7400 model will run on a 667MHz front-side bus and come with 4MB of L2 cache. Core frequency, however, is reduced from 2.2GHz in the T7400 model down to 1.6GHz in the L7400 model. All Core 2 Duo processors utilize virtualization technology enabled and are fully prepared to run 64-bit applications. Like
, the 4MB of L2 cache is shared between the two processor cores.
Intel will debut the Core 2 Duo Mobile processors in a number of flavors. All prices are for distributors:
Intel Core 2 Duo Mobile Launch
Intel C2D T7600
Intel C2D T7400
Intel C2D T7200
Intel C2D T5600
Intel C2D T5500
This is only the first revision of Core 2 Duo, or
. Today's Core 2 Duo notebooks will be based on Intel's highly successful
platform, but the company will be phasing this Centrino platform out around Q2 of 2007. At that time,
Intel will move in its
which uses the GM965 and PM965 Express chipsets and adds the ICH8M and ICH8M Enhanced Southbridges.
will replace Intel's 945GM Express chipset. This next generation of
processors will utilize an 800MHz front-side bus, slightly higher clock speeds and a different socket design.
According to Intel roadmaps, Core 2 Duo processors will make up for more than 55% of its total mobile processor shipments by early 2007. Additionally, Intel expects that dual core processors for the mobile platform will exceed 95% of its production output -- single core processors are definitely on the way out.
Intel roadmaps reveal impressive power consumption numbers for Core 2 Duo processors. Intel claimed on the average, Core 2 Duo processors will have a higher performance-per-watt ratio than existing Core Duo (
) processors. However,
previously reported that
those with a concern for battery life are more than likely better off with notebooks based on Core Duo
processors. The top of the line
processor, the T2700, has a TDP of 31W at 2.33GHz clock frequency. All Core 2 Duo Merom processors have a TDP of 34W, including the 1.66GHz T5500. By comparison, the 1.66GHz
has a TDP of 27W.
Look forward to seeing
versions of the existing Core Duo notebooks available today since
is pin-compatible with
processors. However, don't expect to buy a
off the shelf and stick it into your notebook -- the majority of notebooks manufactured today, including the recent MacBooks, actually have the processor soldered onto the motherboard rather than socketed. Furthermore, when
gets its next speed revision at the Santa Rosa launch, any new processors based on the
will have a new socket

64bit Notebook and memory
8/28/2006 3:24:43 PM
It great to have this cpus but there is a signficant problem with it usefullness.
The main purpose to have 64 bit processor is because of larger than 4Gig memory - main for 3d applications and database servers ( which is silly on a notebook - except for demo ).
But I notice with the latest Dell Precision Notebooks - 4Gig of memory option cost more than the notebook itself.
So for 64 bit to usefull onthe notebook, the prices must come down. On the desktop you can get less dense chips and cost is about 1/3 of it on Notebook.
For me I waiting to next platform for Core 2. One advantage this chip has over previous version is single cycle SSE instructions.

First of all, 64 bit is not just for greater than 4GB of memory. There are numerous applications that will benefit greatly from 64bit even with less than 4GB of memory. One of the most important for my line of work is 3D rendering.
But yeah Dell's memory upgrade options are insane. On the M1210 4GB costs $3,000. However you can get that amount of memory online for around $1,200-$1,500. Still a 2GB SODIMM is about %600 more expensive than a 1GB SODIMM. That just sucks ass.

Yeah ouch talk about gouging, while I do expect some sort of premimu for double density modules 600% just seems skyscraperish.
So the sweet spot for now is just 1GB SO-DIMM's.
Though Merom is a nice upgrade over Yonah though as it brings about all the additional functions of Core based architecture.
