The 73xx series (Tigerton) series are what interest me. I want more cores per box than the max of 8 with the 5xxx can provide. Less boxes, less management, probably less power consumption too.

The next generation of processors is here, pushing performance to an even higher level. Intel's Core 2 Extreme QX9650 is the first desktop processor based on the company's new, smaller 45-nanometer (nm) manufacturing process, code-named Penryn during its development. The process lets Intel put more transistors on the processor, while still reducing its size, heat, and power consumption.
Intel has introduced two significant changes with the QX9650. First, it boosts the amount of Level 2 cache (which can speed operations that access memory) from 8MB to a whopping 12MB. It also introduces a new set of instructions, Streaming SIMD Extensions 4 (SSE4), which can significantly speed operations that deal with graphics, video, and audio—for example, video encoding and games.
The QX9650 requires a motherboard based on the Intel P35 or X38 chipset. If you're upgrading an existing system to a QX9650 CPU, you'll probably need to update your BIOS to support it. Like Intel's previous high-end processor, the QX6850, the QX9650 features four processor cores and runs at a native speed of 3GHz.

To make the jump from 65 nanometer to 45 nanometer processor technology, Intel Corp. redesigned the transistor, an advancement that one analyst said will usher in a new era in technology.
The normally little-talked-about transistor is the building block for the processor. And Intel changed out critical materials in its redesign, trading polysilicon for a metal gate and using hafnium oxide as an insulator. The better insulation means there's less energy leakage, and the metal gate is a better conductor, moving the current through faster.
All of that enabled Intel to make the move from 65nm chips to the 45nm Penryn family of processors while reducing heat output and energy consumption and without inducing major energy leakage.
45nm Penryn chips will extend Moore's Law

Meet the new Penryn, same as the old Penryn. Centrino 2's 45 Express chipset brings the front-side bus up to 1066MHz, but other than that, this is the same Penryn we've already been playing with for months.
Leading the mobile Penryn pack is a Core 2 Extreme X9100 processor, which runs at a blistering 3.06GHz on a 1066MHz front-side bus. This chip is intended for hard-core gaming machines, and was demonstrated on a notebook running Assassin's Creed fluidly utilizing a pair of Mobility Radeons in Crossfire.
If two cores aren't enough for you, Eden let slip that a mobile quad-core CPU will appear before the end of the year with a TDP of just 45W. This chip may have been the most exciting thing announced at the Centrino 2 launch event, although the move to a 1066MHz front-side bus is certainly interesting. With that, Intel's mobile processors are finally up to speed with the first generation of Core 2 Duo desktop CPUs—with the addition of SSE4 support, a 45nm Penryn core, and roughly half the power consumption. That's no small feat considering that the X9100 is roughly as fast as many desktop Penryns already on the market.

Intel's new Hi-k 45nm processor
Added: January 18, 2008
The 45 nanometer (45 nm) process is the next milestone (commercially viable as of November 2007) in semiconductor fabrication. Intel started mass producing 45 nm chips in November 2007, AMD is targeting 45 nm production in 2008, while IBM, Infineon, Samsung, and Chartered Semiconductor have already completed a common 45 nm process platform. By the end of 2008, SMIC will be the first China-based semiconductor company to move to 45 nm, having licensed the bulk 45 nm process from IBM.
At IEDM 2007, more technical details of Intel's 45 nm process were revealed:
160 nm gate pitch (73% of 65 nm generation)
35 nm gate length (same as 65 nm generation)
1 nm equivalent oxide thickness, with 7 Ã… transition layer
gate-last process using dummy polysilicon
9 layers of low-k Cu interconnect, the last being a thick "redistribution" layer
contacts shaped more like rectangles than circles for local interconnection
lead-free packaging
1.36 mA/um nFET drive current
1.07 mA/um pFET drive current, 51% faster than 65 nm generation, with higher hole mobility due to increase from 23% to 30% Ge in embedded SiGe stressors

45nm...What Does It Mean?
Intel's new 45nm Penryn microprocessor relies on a new recipe that combines the element Hafnium and metal gate technology to increase performance and significantly reduce eco-unfriendly, wasteful electricity leaks. But what does that mean?

Intel® 45nm high-k metal gate silicon technology is the next-generation Intel® Core™ microarchitecture. With roughly twice the density of Intel® 65nm technology, Intel's 45nm packs about double the number of transistors into the same silicon space. That's more than 400 million transistors for dual-core processors and more than 800 million for quad-core. Intel's 45nm technology enables great performance leaps, up to 50-percent larger L2 cache, and new levels of breakthrough energy efficiency.
Smaller transistors pack the performance punch
Intel's had the world's first viable 45nm processors in-house since early January 2007—the first of fifteen 45nm processor products in development. With one of the biggest advancements in fundamental transistor design in 40 years, Intel 45nm high-k silicon technology can deliver more than a 20 percent improvement in transistor switching speed, and reduce transistor gate leakage by over 10 fold.

Get Inside an Intel 45nm Chip Factory
Intel will launch its first 45nm chips made with reinvented transistors that use a new Hafnium-based high-k metal gate recipe. Take a look inside Intel's 45nm factories where these chips get made. See the many layers or floors of the factory and the automated shuttles that take the wafers from one step to another to ultimately produce millions of Intel's 45nm chips. These buildings are some of the cleanest in the world and so large that 17 football fields can fit inside!
