Nvidia Makes a Stab at a New GeForce GT 640 Version with GDDR5 Memory

The Internet is filled with rumors about the upcoming release of a new graphics adapter from Nvidia manufacturers. According to the available information, Nvidia is going to update its recently introduced GeForce GT 640 with DDR3 memory type version and to implement advanced tools in their novice product. The implementation of GDDR5 memory will result in the perceptible increase of bandwidth, as well as, of clock speed.



The new graphics card is supposed to exceed its prototype and predecessor in overcklocking showings too. This improvement will be achieved due to the integration of power connector 6-pin PCIe. To contrast both models, the latest version with DDR3 memory employed PCIe expansion slots as power supply tool.


The newer version will be able to operate on 950/5000 MHz, while the older one used to show 797/1782 MHz. GeForce GT 640 (GDDR5) will be based on GK107 processor with 384 CUDA cores and 128-bit memory bus. It is supposed that the memory volume capacity is …

Deepcool is preparing a new cooler with heat pipes

Deepcool production company of inexpensive and quite efficient cooling systems has provided a sample of CPU cooler — Big Frost (tentative codename), which is an extension of current Frostwin model. Previous model has 4 sintered powder heatpipes, which conduct heat from the processor to protect it from overheating. Also, like a new model, it has 120mm fans.



New model has a simple design, but strict, almost «standard», forms will not prevent it from showing a decent performance. It works with less noise and performs an effective cooling. Big Frost consists of a nickel-plated copper base with a miniature auxiliary radiator, six U-shaped copper heatpipes, each of 6 mm in diameter, and two sections of aluminium plates of similar thickness. Pre-installed fans are running at different speeds. One turns with intensity of 1300 r / min (22.6 dB noise), the other — in the range from 900 to 1500 rev / min (21,4-32,1 dB).


Dimensions of construction form 126x136x159 mm, weight — …

Promising Speed Forecasts for AMD Radeon 8000 Sea Islands

AMD is continuing its work on the new GPU generation codenamed ‘Sea Islands’. The new series is prognosticated to be released in the coming winter. All the products with this GPU will be branded Radeon 8000. AMD manufacturers claim that their new graphic processing units will be 40% more efficient due to the implemented advanced technologies. There is not so much news about the future GPU architecture, although cardinal changes are barely possible.



Sea Islands chips will be equipped with 5.1 billion transistors as compared with the current 4.3 billion items applied in the products. This augmentation will facilitate the increment of efficiency. The chips will be developed according to the already tried-and-proven 28 nm technological requirements. The increase of transistors is not as large due to the adherence to the ascribed norms. It should be underlined that the implementation of the old technologies does not imply the considerable warming up of the chips; the developments …
