Intel will release Extreme Edition Core i7 processor within the near future, as well known overclocker Fugger has posted some early benchmarks and overcklocking results for the Core i7 Extreme Edition 975 which comes clocked at a default speed of 3.33GHz.
Although this is hardly a huge step up from the current 965XE part which is clocked at 3.2GHz, the new 975XE seems to overclock much better. Using a Gigabyte EX58-Extreme motherboard, Fugger managed to push the new CPU to 5.26GHz without any problems and with the help of a pair of Radeon HD 4870 X2 graphics cards, him and his partner Mikeguava managed to break 47,000 in 3DMark 05 which is a new world record. Its likely that Fugger will achieve even higher scores with this CPU given time and it looks like all the overclockers out there will have a new toy to play with in due time. As there are other chips in circulation already, wed expect more benchmark results to pop up over the next few weeks.

Intel Core i7 Overclocking - Core i7 Overclocking
|
You will se how high these processors(Nehalam processors- the 920 and the 965EE) can be overclocked using the ASUS P6T motherboard. It is very interesting how Intel works with the QPI bus v/s Multipliers. After a bit of tinkering around, we eventually found the sweet spot on each of these processors. So it was now time to see how hot these babies got on a one hour OCCT stress test.
Intel Core i7 Overclocking - Core i7 Overclocking
No surprises with the temperatures for the 130W CPU’s especially the 965EE hitting 4GHz on a stock air cooling solution.
The voltage configuration set to Auto at first and increased the BCLK from 133 MHz to 150 MHz as a jumpstart. From there steadily increased the BCLK in increments of 5 MHz. Guys at tbreak managed to hit the wall at 180 MHz which was the limit at which we could enter Windows, but the OCCT test threw off a bit and there was no stability.
With the bus speed down in 2 MHz decrements with stress tests at each level and success arrived at 168 MHz. Next up was the Multiplier, which hit 4 GHz on the 965EE while the 920 stayed at 3360 MHz due to its multiplier limit of 20x. Increasing the voltage wasn’t doing us any good as we weren’t able to manage a stable one hour stress test. Although, higher clocks could be possible with a better cooling solution and a lot more time.
Conclusion:
Intel Core i7 has started out as a good overclocker. Getting to the sweet spots wasn't really difficult and all this achieved on the stock air cooling solution provided by Intel and stock core voltages. The overclocked Core i7’s do make excellent performers and those seeking not only thrills from overclocking their CPU’s are in for a ride.

The Fastest Processor Ever :Intel Core i7 Extreme
|
Intel has launched its most advanced desktop processor ever called the Intel Core i7 processor. The first member of a new family of Nehalem processor designs, it speeds video editing, immersive games and other popular Internet and computer activities by up to 40 percent without increasing power consumption.
Intel Turbo Boost Technology automatically adjusts the clock speed of one or more of the four individual processing cores for single- and multi-threaded applications to boost performance. The Core i7 processor more than doubles the memory bandwidth of previous Intel “Extreme” platforms, speeding the transfer of computer bits and bites in and out of the processor with Intel Quickpath Technology. Intel’s Hyper-Threading Technology allows multiple computing threads to run simultaneously, effectively enabling it to do two things at once, so the Core i7 quad-core processor delivers 8-threaded performance.
Each Core i7 processor has an 8 MB level 3 cache and three channels of DDR3 1066 memory to deliver the best memory performance of any desktop platform. Intel’s top performance processor, the Intel Core i7 Extreme Edition, also removes overspeed protection, allowing further increase in the chip’s speed.

Intel Core i7 CPUs make their official debut
|
Top silicon maker and breaker, Intel Corporation has now officially launched the first processors based on the Nehalem architecture. Coming to take over the high-performance desktop segment, the Core i7 CPUs make use of a new Socket - LGA1366, are paired up with a new chipset (X58) and feature a heap of more or less new features.
"Intel has delivered the fastest desktop processor on Earth to the most demanding users on Earth, the ones who are using their PCs for video, gaming and music," said Patrick Gelsinger, senior vice president and general manager of Intel's Digital Enterprise Group. "When you couple what is Intel's biggest leap in chip design with other incredible innovations like Intel's solid state drives, the Core i7 processor has redefined the computer of tomorrow."
Going from 2.66 GHz (Core i7 920), through 2.93 GHz (940) and topping 3.2 GHz (Core i7 965 Extreme Edition), the new 45nm CPUs have four cores and eight threads, integrated triple channel DDR3 memory controller, 8MB of L3 cache, a TDP of 130W and can brag with the auto OC technology called Turbo Boost. As pretty much every performance preview/review has confirmed, the Core i7s are fast as heck but to get them you'll have to dig relatively deep in your pockets as the 'cheapest' model, the Core i7 920, has a price tag of $284 while your average X58 motherboard costs even more (and we didn't include the DDR3 kit). As confirmed by Intel, the Core i7 940 is priced at $562 while the 965 EE is at $999.

Core i7 with decreased TDP in 2009?
|
RRumors on Intel's Core i7 are filling the streets. Fudzilla reports that Intel will lower the TDP of its Core i7 processors in 2009.
The claim is based on a quote by an Intel representative. During the IDF in Taipei it would've been mentioned that Intel is working on two processors with a lower TDP than the current 130 Watt. These two are claimed to be scheduled for release in the first half of 2009
Thermalright's Ultra 120 Extreme to be Core i7-ready
|
Thermalright is preparing its flagship CPU cooler, the Ultra 120 Extreme ( eXtreme) for Intel's upcoming Core i7 processors and will soon release a new package that will make it Socket 1366 compatible.
Seen below, the Core i7-ready cooler is the 'original' Ultra 120 Extreme paired up with an LGA1366 mounting bracket. More intriguing is the 120mm fan which will apparently be included with the heatsink. No word on pricing or retail availability but we'll find out both soon enough.

Core i7 overclocked to 4.2GHz
|
Because Core i7 Extreme has multiplier unlocked, so overclockers can easily OC to 4.2GHz by pulling up the multiplier. But like Phenom, the bus speed can not boost a lot. So we’d better drop our thought, they are not Core 2 anymore, so we may not have chance to see 500MHz+ bus speed.
If you read the everest benchmark chart and 3Dmark Vantage, the performance looks quite impressive.

Core i7 4.2GHz Intel Core i7 Extreme 965 unboxing

Although we still don't know when the official announcement will take place, Intel is expected to unveil its next generation Core i7 processors, based on the Nehalem architecture. As with most other highly anticipated hardware products, details have already surfaced on the Internet, which literally means that, by the time the Santa Clara, California-based leading chip maker decides to officially unveil the product, most users will already have a general idea of what to expect from it.
Photos of the company's upcoming Core i7 Extreme processor have popped up on the Internet, clearly showing everything you are to look for from a straight out-of-the-box offering. While the packaging isn't that which will be seen in stores at insane ($1000+) prices, everything else is there, including the new boxed cooler and, of course, the star quad-core CPU. The Core i7 Extreme 965 features four cores and eight threads, 8MB of L3 cache, a triple-channel DDR3 integrated memory controller and a passion for one little chip known as the X58.This also includes the new and improved cooler, specifically designed to ease temperatures for Intel's next-to-be flagship processor.
The Core i7 920 and Core i7 940. These will come with core speeds of 2.66GHz and 2.9GHz, respectively, and will provide a total of 8MB of L3 cache. As far as pricing is concerned, they will be available for approximately $284 and $562.

The cooler is certainly quite an impressive looking beast with its mixture of copper and aluminum fins, not to mention the sheer size of the thing.
