Hitachi Global Storage Technologies unannounced DeskStar hard disk drive with 4TB capacity first in Japan. Since the new 4TB drive belongs to Deskstar 5K family, it will barely attract performance enthusiasts.

Thai-made parts, assemble 0S03361 China achieved 3.5-inch HDD 4TB capacity under 1. The maximum capacity is based on the previous HDD 1 3TB, this product is currently exceeding the maximum capacity it.

Hitachi GST Deskstar 4TB hard disk drives (model 5K4000, model number HDS5C4040ALE630) have 32MB cache, use Serial ATA-III (SATA-600) interface and utilize 4KB advanced format. The Deskstar 4TB hard drives use CoolSpin technology that promises to reduce power consumption without compromising performance. Actual spindle speed of CoolSpin-based drives is not published, but some estimate that it is 5900rpm.

Cache size is 32MB. SATA interface supports 6Gbps. In addition, automatically controlling the rotational speed of the spindle motor to balance power consumption and noise level "CoolSpin Technology" and the technology 4KB sector "Advanced Format" adopted, the package has been installed in the cache of 32MB that have been described.

The 4TB internal hard drives from Hitachi are available in select stores in Tokyo, Japan can be sold at ¥26800 - $345, €258. [Akiba PC Hotline]

Test results of the evaluation before the start of the technical features of the Core i7-3960X'in is important to remember briefly. New 6-core processor with 32nm process technology as a standard 3.30GHz 'serves as the core operating frequency of 3.9GHz and Turbo Boost technology to increase a up. For each kernel that supports dual-thread processor, 15MB memory capacity of its single-threaded applications because it seems to bring a significant performance increase to desktop systems by considering the Intel processor seems to be the highest memory capacity.

Sandy Bridge-E series is the most striking feature of the new generation of Intel processors have a four-channel memory support. DDR3 up to 1333MHz officially support overclocking by offering higher memory frequencies, but also run on processors, memory bandwidth will not recognize competing applications seem to have come to the fore. Core i7-3960X-E series, including the Sandy Bridge will be 130 watts thermal design power of all processors. X79 chipset motherboards for the new processors will be used in the last quarter of the release date. Although there has not yet been able to market in October with the new processors.

Let's come a performance level. According to tables prepared by the Intel Core i7-3960X, the performance of core importance, and Pov-Ray Cinebench tests, based on the Westmere architecture, which has the same number of cores and a slightly higher than the base frequency of 13% and 12%, respectively, the Core i7-990X'ten manages to be faster. At this point, the difference is mainly due to innovations possible to say that Sandy Bridge architecture. Pro Show Gold 4.5 and up and down to the test with similar results were obtained in 15%, the biggest difference came to 36% of the difference in 3DMark 11 and we see that the physical test.

The Intel Core i7-3960X Extreme Edition will be priced at $990 and produced as many as 1,000 units. It will compete with Advanced Micro Devices (AMD) which last month started shipping the eight-core FX-series.

The Cortex A7 chip offers five times the energy efficiency compared to the ARM Cortex A8 processor and is one-fifth the size. The chip is specifically designed for smartphones and will enable a sub $100 smartphone in 2013 to have the performance level of a $500 smartphone of today.

The multi-processor core Cortex A7 will be fabbed at the 28nm process node with resulting surface area of 0.45mm^2. ARM said the chip will be fully backwards compatible and available in both single and dual-core versions.

ARM also introduced its "Big.little" processor concept with the Cortex A7. The idea here is to have two processors inside a mobile device like a smartphone. The example given was a Cortex A7 coupled with a Cortex A15 so you have energy efficiency but also performance.

With two processors in place, the right one can be used for the right job. The Cortex A7 will be used for "always on and always connected tasks" such as phone calls and text messages, whilst the larger Cortex A15 will deal with more demanding tasks such as videos and gaming.

According to ARM this can yield up to 70 per cent energy savings on common workloads compared to a current high end smartphone and will therefore increase battery life. What's also important is that the operating system and apps software knows nothing of the processor switching so it doesn't get in the way. source:
