We recently reported about NVIDIA intentions to release certain new chipset for Intel processors, which combines the properties of graphic core and south bridge, we subjected this information to critical analysis. First , there were some technical contradictions - sandy bridge processors, for example, already possess the built-in graphic core, and it is hardly  inferior to NVIDIA solution  . Furthermore, this idea disperses from the recent words of company management  , which clearly indicated the inevitability of essential decrease in the release volumes of chipset as a whole.

According to our own source the preparation for announcement of new chipset NVIDIA for Intel platform  is invention. This producer made the final decision to end the development of chipset for Intel processors .

Mobile devices are actively using processors with ARM- architecture: first in this year they will be actively used in plane-table computers, where the low energy consumption is not only  important, but also developed functional possibilities, or productivity. Intel attempts to compete with ARM- processors with the aid of economical processors versions with the x86- compatible architecture, NVIDIA counts on tegra processors with ARM- architecture and built-in graphic core, AMD thus far controls these processes, attempting to move its x86- compatible architecture bobcat.

ARM and Globalfoundries already reported about the successes in the mastery of 28 nm technical process. Associate published the slide from the presentation, which demonstrates some characteristics of future 28 nm ARM processors .

As it is explained, in the dual core configuration these processors can work at the default frequency of 2.5 GHz, and after a certain increase in the default voltage they can be overclocked to 2.8 GHz. Here we deal with some dynamic overclock technology, analogous to the already used by Intel and AMD. If we considers that produced on 40 nm technologies  ARM processors can work only at the frequency of 2.0 GHz, then the progress is obvious. Of course each ARM client form the fundamental characteristics of processor, and not all series products will work at frequencies more than 2.0 GHz.

Samsung company officially declared about the intention to present the plane-table computer galaxy tab on the exhibition IFA 2010 in the beginning of September. The characteristics of this plane-table device are 7 inch screen  Galaxy tab will appear first in Europe, USA and Asia, where  will have time to appear on sale in this year, it will be extended exclusively by honeycomb connection operators and by providers.  

Already in the middle of September Galaxy tab will appear in European connection operators  . 7 inch screen with 1024 X 600 resolution is sufficiently compact, and mass is 380 gram. For comparison: iPad version without 3G has the weight of exactly 300 gram and the presence of 3G- modem added to the weight  50 gram. However, iPad possesses larger display, but this already a question of user preferences. The overall dimensions of samsung device are equal to 190 X 121 X 12 mm.

The operating system google android 2.2 over the long term can be updated to version 3.0. Even now this platform support Adobe flash 10.1. Furthermore, Galaxy tab is characterised by two Web- cameras. One, with 3.2 MP,  it is equipped with light-emitting diode flash, and it can record video with 720 X 480 points quality. The second camera is 1.3 MP. The regular battery capacity 4000 will be sufficient for seven hours of continuous video playback , or ten hours of different work.

Galaxy tab is based on ARM cortex-A8 processor with 1 GHz frequency and the graphic system powerVR SGX540. For storing data can be used 16 Gb or 32 Gb solid-state memory, additional volume is accessible through the slot for microSD  . Accelerometer, illumination sensor  , geomagnetic sensor and GPS receiver. For connection with the external device are provided the adapter wi-Fi (802.11n) and modem with 2.5G/3G networks support   , and also bluetooth 3.0 controller  . On essence, Galaxy tab can be used as large smart phone for vocal and video call.

At the end of May we revealed certain zalman cooler on GeForce GTX 4xx from ZOTAC production.

Now the cooler zalman VF3000F is accessible on retail. Overall sizes (239 X 98 X 51 mm) and the mass (430 gram.) the device possesses the extended rotation speed range  two 92 mm fans: 1400-3000 rp/min instead of previous 1300-2500 rp/min the noise level at the maximum speed in this case grew from 32 to 33 dB.

From the copper base there are five heat pipes , which penetrate the aluminum radiator.

This cooler is as before completed by unit of fans rotation control fan mate 2 and thermal-paste ZM-STG2.

Accordingly, this radiators construction excludes the compatibility of cooler with other video cards, except GeForce GTX 465/475/480.
