Intel watercools Nehalem to 4.61GHz

François Piednoel, and the rest of its performance analysis group, have showed us Nehalem, Core i7 PC water cooled all the way to 4.61GHz.


They did it on an Intel desktop motherboard powered by Intel's desktop control center, something that lets you overclock from Windows. The voltage was all the way to 1.44V, whereas the chipset needed 1.21V.Host frequency clock, something that we used to call FSB speed of the machine is 144MHz, which multiplied by the 32 multiplier gives you the 4610MHz number.

The CPU temperature was at 61 degree Celsius while the CPU Voltage regulator was at 31 °C and chipset at 41 °C. The clock is much higher than the one you can score on Phenom II, but Intel’s CPU used here is much more expensive.

Nehelem, Core i7 is definitely better water overclocker than Phenom II but Phenom II still overclocks higher at 6GHz+ domains.

Intel announces Core 2 Quad Q6600 EOL

Intel recently announced that the company will take 2.4GHz Core 2 Quad Q6600 orders until 8th of May, 2009, and will ship the CPU in box and tray version until August 7th 2009 and July 10th, 2010 respectively.Intel explained this move with the consumer demand shifting to higher performance CPUs. The Quad Q6600, which we tested way back, was insanely popular as it was a great bang for buck as it featured a decent price and overclocked nicely.

Due to quite a demand for it, it managed to outlive and certainly outshine its brethren, as it broke through quite a number of EOL announcements. Since this is a Kentsfield based CPU built in the now obsolete 65nm process, we do not expect it to do so again, so we’ll start baking its retirement cake.

Intel to release energy-efficient quads and cut CPU prices

Intel was planning the release of the Core 2 Quad Q8200s, Q9400s and Q9550s, its first Core 2 Quad CPUs to have a TDP of just 65W for this month. The launch is slated for Sunday, January 18 and it will also see to the introduction of two new low-cost dual-cores, the E7500 and E5400. Moreover, Intel will cut the price of six models, the Q8200 (features a 95W TDP), the E7400, E5300, E5200, E2220 and E1400.


All info regarding the January 18 changes can be seen in this chart. Intel is also rumored to be cutting prices of the rest of its Core 2 Quad line-up later on, this month.

Intel and AMD new quad-core chips

AMD and Intel ended 2008 with a new quad-core hit. There is Intel Core 2 Quad Mobile Processor Q9000 that is the latest mobile processor from Intel and it has been housed in the Acer’s recently launched 8930G laptop, and AMD’s Phenom II processors that have popped up online for consumers’ pre-orders.

As mentioned earlier, the Intel Core 2 Quad Mobile Processor Q9000 has been housed in the Acer’s recently launched 8930Gnotebook and this processor is running with 12MB of shared L2 cache in this laptop an with 2.53GHz clock speed rate upward and a 1066 MHz front side bus.

Aside from the Q9000 chip, there are many other impressive features in the new Acer notebook that also include DDR3 memory of 4GB, an 18.4inch LCD, a 1/2TB SATA hard disk and a NVIDIA GeForce 9700M GT graphic card.

Aside from the Q9000, Intel is also release four more mobile processors, while AMD will debut its Phenom II processors publicly at CES next month. This new processor from AMD is already available for pre-orders and it runs at up to 3GHz of speed with an 8MB cache.

AMD 45nm Phenom II analysis and review

Based on the company's 45nm manufacturing process and brought to market a couple of months after the launch of the similar server part, Shanghai, AMD's Phenom II quad-core processors promise higher clock speeds, to better compete against Intel's Core 2 Quad CPUs.

Phenom II 920 and 940, released at clock-speeds of 2.8GHz and 3.0GHz, respectively, will be available to buy in a couple of weeks. We investigate whether the advancements over incumbent Phenom X4 are enough to make them serious contenders in the <£250 market.

AMD finally launches Phenom II and Dragon Platform

AMD's 45nm, quad-core Phenom II has finally arrived. It's available in two flavors, the 2.8GHz X4 920 and the 3.0GHz X4 940 Black Edition, going for $235 and $275, respectively. AMD's naturally touting the ostensible cost savings of the chips . The Dragon platform includes a Phenom II proc, 4800-series Radeon HD graphics and a 790-series motherboard, all of which should combine for low power consumption -- up to 40 percent compared to Phenom processors. Where the Phenom II definitely wins is the fact that some AMD folks will be able to drop in the chip to existing motherboards, but otherwise it looks like value hounds and performance junkies aren't being served by this new chip.

AMD finally launches Phenom II

Performance

The Phenom II's integrated memory controller and HyperTransport interface give it a technical edge over competing Core 2 Quad chips, which lack those features. Intel moved to an integrated memory controller and began incorporating its own version of HyperTransport--dubbed QuickPath Interconnect--only with its Core i7 platform. The integrated memory controller and HyperTransport interface allow Phenom II processors to achieve a higher memory bandwidth than Core 2 Quad processors can, by eliminating the bottlenecks created by a frontside bus and an external controller. The arrangement, in theory, improves system performance.

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.

New Info of Phenom II X4 940 Unveiled

AMD Phenom II X4 is ready to debut this Thursday, though it still looks quite mysterious. The latest information indicates Phenom II X4 940 performs as well as Intel Core 2 Quad Q9450/Q9550 while costs a little bit lower.

The power consumption of Phenom II X4 940 ranges from 60 to 70 Watt under load.With the help of a normal air-cooling cooler, the processor can be overclocked between 3.2 to 3.6GHz without increasing voltage.

AMD unleashes linux code for general purpose computing

AMD, the chip rival for Intel has released “the fundamental Linux code” that is needed to develop open-source 3D-acceleration drivers for its R600 and R700 ATI graphic-processors series.

The news is intended for those who want to create drivers for potent GPU series of ATI Radeon HD 2x00, HD 3x00 (both R600), and Radeon HD 4x00 (R700). Also, unleash of open source code is good for Linux-lovers who have access to the R600/700’s 3D powers.
The announcement made by GPU to support the recently released open-source OpenCL 1.0 allowing GPU to be used for general-purpose computing (GPGPU), it is expected that GPUniverse is moving slowly toOpen Source Software (OSS) model.
The OSS future looks bright for GPUs. The segment was still new to AMD as Intel is open with its drivers. OSS development should proceed swiftly, both in 3D acceleration and GPGPU.
