Intel® Wide Dynamic Execution. Enables the delivery of more instructions per clock cycle for shorter execution times and improved energy efficiency—accomplish more simultaneously and with greater efficiency.

Intel® Intelligent Power Capability. Turning off portions of the processor when they aren't being used improves overall energy efficiency and reduces heat production, resulting in a quieter, more energy efficient system.

Intel® Smart Memory Access. Increasing available data bandwidth means more multitasking with less slowdown—run more demanding applications simultaneously and accomplish more in less time.

Intel® Advanced Smart Cache. Placing data closer to the processing cores improves platform responsiveness and performance with a wide range of applications.

Intel® Advanced Digital Media Boost. Accelerates performance with a wide range of applications, including video, gaming, speech and image, photo processing, encryption, financial, engineering and scientific applications.

Intel® HD Boost. Available only on the latest 45nm Intel processors, this revolutionary technology takes Intel® Advanced Digital Media Boost and improves it even further enabling significant gains on the latest SSE4 instruction set. SSE4-optimized applications, such as video editing and encoding in high-definition resolution, will see additional performance improvements

Multimedia
With professional-grade photo, music and HD video editing software readily available for consumers, it's becoming increasingly popular to create, edit, and share entertainment with friends and family. Unfortunately, these same applications are notoriously performance hungry. Built to handle the most demanding software, the four cores of the 45nm Intel Core 2 Quad processor help ensure that when you're working with high-resolution photos, exporting your next audio mashup, or editing HD-quality home movies, your computing platform will be able to keep pace with your creative muse.

Multitasking
A computing platform featuring a new 45nm Intel Core 2 Quad-Core processor maximizes processing efficiency, allowing computer users to juggle multiple projects in multiple applications without experiencing the slowdown typically seen with traditional single-core processors.

Gaming
Next-generation gaming is more than just pretty environments and smooth motion. Behind the incredible visual realism of waterfalls or the unlucky ricochet of a bullet are intense, high-speed calculations of asset streaming, terrain generation, 3D rendering, and physics effects. When running select next-generation games, each of the cores in the Intel Core 2 Quad processor can be dedicated to each of these individual processes, resulting in smoother, more lifelike graphics and further blurring the line between virtual and reality.

By Mark #1 HALL OF FAMEVINE VOICE on June 16, 2008
I've been building a number of systems lately, and needed to put together a few of my own too. So in addition to building several servers based on newer Xeon chips, I also have had the pleasure of building two core 2 quad systems recently.

Intel's entire lineup of new chips have some real positives. The Intel Core 2 Quad Q9450 Quad-Core Processor, 2.66 GHz, 12M L2 Cache, 1333MHz FSB, LGA775 is a great chip in particular that offers you some of the benefits of a server CPU at a home PC price point. It's also very compatible with the types of boards and set-ups that most gamers or heavy application users (read Photoshop :) ) will want in their rigs.

Like the Xeon Quad-core - X3350, the 9450 also gives you the 12 MB of L2 Cache, which is the largest easily available through retail channels and 50% larger than the 6600. True, for $200 you can get the Intel Core 2 Quad Q6600 here on Amazon. It has a very similar clock speed (easily over-clocked) and a respectable 8 MB of L2 cache, which is nothing to sneeze at. Like I said, I used that guy in my personal box, but I did find that it was possible to locate the 9450 at a similar price. So while Amazon's price does vary, if you do your research you can get the larger cache and slightly faster clock speed of the 9450 for the same price as the 6600.

Q9450 comes with impressive specs, but real-life performance often does not scale well with the numbers on paper. This is not the case with this thoroughly modern processor, though. It breezes through the tough video application at 30% CPU utilization, the same application that had brought the low-end dual-core it replaces to the knees.

What pleases me the most, however, is how cool this CPU runs. I had intended to make this computer as quiet as reasonably possible. Therefore, both the CPU and the GPU had to be passively cooled. I got a big heatsink (Scythe "NINJA 2" 6Heat Pipes CPU Cooler) for this purpose and it turned out to be an overkill. The CPU barely registers a little warmth even after heavy lifting. It is in fact not any hotter than the chipset. In contrast, the GeForce 8800GT, which is rated as the most energy-efficient GPU among the latest generation, feels like hot enough to fry an egg.

Given that Nehalem "Core i7" is just around the corner, the days of LGA775 are literally numbered. The upgrade path will end with the $1400 QX9770, which is exactly the same processor as Q9450 but with a 20% frequency bump. Such a frequency difference is usually inconsequential in real performance, not to mention the 55% extra heat and noise associated. So, Q9450 may well be one of the best LGA775 CPUs ever for all eternity, although Intel just released the new E0 stepping of Q9550 in August, 2008. Q9550 is over-clocked 6% over Q9450, which is a very minor difference. But the pricing on Q9550 has also been lowered from $530 to $320, so maybe it makes sense to buy that now. I don't regret getting the Q9450 though.

Works Great! Upgraded from Intel Core 2 Duo E4500. This makes a night and day different in boot up time and response. Multi-tasking is a lot quicker. E-Power shipped very quickly. Big props to them for quick shipment! They also provide a 45 day warranty as well.

There is something eminently satisfying about seeing FOUR cores listed during BIOS POST. TWELVE Megabytes of L2 cache? Fast, fast, fast.

Installation was slightly annoying though. The processor/heatsink attaches to the motherboard with some plastic thumbscrew rubbish. It requires a specific order to press and turn the thumbscrews. Removal of the heatsink requires a bizarre turning, lifting, then turning combination of movements. It made me long for the days of using actual METAL screws to attach heatsinks to motherboards.

Also, the thermal paste appears to discharge onto the cpu after the first plastic thumbscrew is turned so be careful. Get it right the first time or plan on cleaning up the paste and possibly adding additional paste.

Am very happy with the CPU. Am not happy with the heatsink design.

I thought the upgrade to Win7 64 bit with 8GB RAM would have solved some issues with my ProTools music software. But I was at the minimum requirement with the 2 cores. The upgrade to the Quad Core was the answer. I chose the Q9450 for the speed and cache. My overall PC experience has improved, although I was not dissatisfied with the E8400 either. You can't know until you try it.

First off, this processor is undoubtedly the best deal out there among the Intel quad-cores. Compared to the Q9550 at $570 and the QX9650 at $1000 or more, this CPU is a certified bargain. It has all of the features of those others (at least as far as I know) but just runs a touch slower (2.66 GHz instead of 2.8 or 3.0 GHz.) I wouldn't pay more for one of the other quad-cores unless you insist on having the fastest thing out there. There are other places in your system to spend your money where you'll get more performance for your dollar.

As much as I like the CPU, however, it would be a shame to install it with the terrible stock fan included in the box. Installation was a pain (the flimsy plastic pins kept popping out of the holes in my motherboard) and it is noisy and relatively ineffective at maintaining temperatures. Take some of that money you saved by opting for this CPU instead of a higher model quad core, and buy a quality CPU cooler separately. Your system will run quieter and cooler.

In short, put this (and an aftermarket CPU cooler) on your short list if you're building a system.
