HP HPE PC Edition

HP has announced the HP Pavilion Elite High Performance Edition (HPE) PC. The manufacturer states that the system is designed for power-intensive gaming. The HPE is based on an Intel Core i7 processor, an nVidia GTX 260 special edition graphics card, up to 6 GB of DDR3 memory and 2TB of hard disk capacity. The HP Extra Quiet technology with internal ventilation is to keep the HPE both cooled down and silent enough to be placed anywhere.

Other features include a DVD-burner, integrated wireless, TV-tuner, Blu-ray player (in one of the models) and MediaSmart software 3.0. A pocket media drive bay is to simplify upgrading and expanding.

The HPE will be released later this month. HP specifies a recommended pricetag of €1.199.

Core 2 Duo E8600 overclocked with MSI P45 Motherboard

Balance performance and power consumption. The overclocked processor and graphics cards is the easiest way to improve the performance of the system, ideally, and no cost. However, there are limits to take into account if you want to enjoy a reasonable relationship between performance and power consumption, since more speed translates into a higher energy consumption. We used an MSI P45 motherboard and a Core 2 Duo E8600 to answer this question: what is the clock speed at which a Core 2 Duo processor delivers the best performance / consumption?

P45 and Core 2 Duo, still a good match.
Although now it seems everyone is only talking of Intel Core i7 and the AMD Phenom II, the dear old dual core Core 2 Duo will remain in circulation for several months. Despite the quad core mentioned above provide a significant performance boost, they are more expensive (Intel) and typically require new motherboards, and DDR3 memory. This will apply equally to future new Intel products, such as chipsets Series 5 (Ibex Peak), which introduce the new processor socket LGA1156 and Lynfield. The new products offer better performance, and probably will fill the gap that exists between the Core 2 Quad and Core i7, but the platform will not be much more efficient configuration of a Core 2 Quad - and more expensive. Ibex Peak is as innovative product, which introduces new features. For these reasons, the Core 2 Duo models will remain attractive for a while ', because many applications do not benefit fully from the four cores.

Platform.
We looked around for a suitable basis for our plan to overclock. The choice of a high-end motherboard, equipped with many features for fans, it was certainly a good starting point, but with the intent to keep the cost to reasonable levels, we opted for a mainstream P45 motherboard. To be more precise, we selected the motherboard MSI P45D3 Neo, a model not equipped with highly advanced features - that many users probably do not use it - but however provides overclocking features we needed. The most advanced P45D3 Platinum would have been our choice in the case of quad-core CPU, but for this project to overclock the Neo is more than enough.

Core 2 Duo Vs AMD Phenom II X4 to reduced tension

VS

When it comes to processors and overclocking ability, the questions that users ask are: which speed is possible to carry a processore? Which tension needs in order to catch up that speed? Which is the better system than usable cooling? which speed is possible to carry a processore? Which tension needs in order to catch up that speed? Which is the better system than usable cooling?

Voltage, clock speed and power consumption
While the clock speed is the first characteristic that identifies the benefits, while the increase of tension is a variable used to reach higher clock speeds, the voltage is the parameter that affects the energy consumption. The increase in clock speed has a lower impact on consumption than the increase of operating voltage, which impacts more heavily. Similarly, the reduction in operating voltage can greatly reduce fuel consumption.

Low-voltage products
Many laptop processors are simply modified versions, to consume less, desktop counterparts. Think of the Intel Core 2 mobile: it is optimized versions, but in certain conditions consume and offer services identical to those of the brothers for desktop PCs. The Core 2 Duo T-series, have a TDP of 35 W (maximum power consumption of 35 watts), while the P series does not exceed 25 watts.
There are versions with low power consumption for desktop processors: AMD provides long-efficient processors, identified by the suffix and (Phenom II X4 900th and 905th, or X4 9350e), Intel Core 2 Quad models offer the "s" which offer the same benefits of regular models, but have a TDP of 65W instead of 95W. Although these processors are usually more expensive, both in idle which are able to reach peak power consumption reduced, as promised.

CPU low cost do-it-yourself ?
Considering the benefits described above, why not change the operating voltage of the processor on our behalf? We took two MSI motherboard, the P45D3 Neo, recently used for the article "Core 2 Duo better when overclocked, and we have matched with a Core 2 Extreme QX9650, along with a 790FX-GD70, used for the tests with the AMD Phenom II X4 955.

Intel Xeon Chip Processor 65 nm

Shortly after the introduction of four new 45nm Xeon processors, Intel announced that four former 65-nm Xeon chips will be the end of life status. The affected chips, four Tigerton quad core processors are the Xeon X7350, E7350, E7330 and E7320, with clock frequencies of 2.93 GHz, 2.4 GHz, 2.4 GHz and 2.13 GHz.

Four Intel Xeon processors can be ordered until February 12,2010, with a final ship date of May 14,2010 for the boxed version, and August 10, 2012 for release tray. So far, the processors are priced $ 2301, $ 1980, $ 1391 and $ 1177, when purchased in quantities of 1000.

New Intel Pentium E6500K processor

It seems that the newly emerged Processor Intel Pentium E6500K is a worthy candidate for overclocking. After Expreview obtained one of the chips, they were able to watch the new 45 nm Wolfdale CPU with unlocked multiplier to 4607 MHz, a respectable. With the help of a K|NGP|n F1 and liquid nitrogen DFORDOG Overclocking Forum Expreview has even been able to overcome the 6 GHz mark. The motherboard is a Biostar TP45 HP, which is available in a package with E6500K Intel Pentium processor, two 1GB memory modules Geil. The retailed in the processor is the equivalent of about U.S. $ 84 in China at this time. Intel expects the chip will become a worthy rival for the new DualCore AMD Black Edition processors, which will also feature an unlocked multiplier.
