Hark! Today marks the arrival of Intel's first 45nm desktop processor
To coincide with the NVIDIA's GeForce 8800 GT launch scheduled for later today, Intel jumped the gun today with its immediate embargo lift on its high end 3.0 GHz
The Extreme Edition QX9650 desktop processor is Intel's first 45nm offering. True to
Intel's "tick-tock" approach to processor design
, all initial 45nm processor offerings will be process node shrinks of the Core 2 Duo architecture. The only feature difference between these processors and the Core 2 Duo
processors announced last year is the inclusion of additional L2 cache,
and higher clock frequencies.
The QX6950 features 12MB of L2 cache, a 1333 MHz front-side bus and a 130W thermal envelope.
The QX9650 will remain Intel's halo processor for the better part of 2008 until the introduction of the next, and possibly last, Core 2 Duo frequency bump. In last 2008, Intel will replace its server and desktop architectures in favor of
its next-generation architecture
Intel representatives claim all media information about the QX9650 is now available for the public domain with the exception of the price. Reviewers are allowed to post all embargoed information at midnight tonight.
Previously leaked Intel roadmaps already indicated that the 45nm Extreme Edition will launch with the standard Extreme Edition price tag, $999. Intel memos forwarded to
indicate the hard ship date for these new processors still remains November 12, 2007. On this date, the company will lift the embargo on all 45nm desktop offerings.
Intel's 45nm offerings are not the only processors expected to launch this November. AMD roadmaps also indicate the company's 65nm native quad-core
Phenom processors will launch late November
. In addition to the new processors, AMD will also announce its
RV670 graphics processor
and RD790 chipset.

This from a review-
We used a plug-in power monitor to check the power draw for our test system and found that Penryn was consistently more frugal with the juice. At idle, Penryn uses 45W less than Kentsfield at 3GHz, although the gap is reduced when you overclock. That’s a huge percentage of the total power draw, dropping the figure from 155W (minus display) to 110W.
In PCMark05, the system is loaded fairly evenly and once again the difference was 30-45W in favour of Penryn. Finally, we come to POV-Ray where the quad-core processors were running flat-out and the power draw was highest of all with a difference in power consumption of 55W at a 3GHz clock speed. When we overclocked the difference was, once again, 30W.
Penryn is a step forward from Kentsfield that offers moderately better performance in day-to-day tasks but when you give it a sniff of SSE 4 it shows a distinct benefit. The much-reduced power draw is very encouraging too. You’d be crazy to spend £649 on the Core 2 Extreme QX9650, but you should most definitely choose a Penryn-based Core 2 Duo or Quad over an older, 65nm model
