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 …

Graphics card Colorful iGame GTX 660 Ti ARES X on sale soon

Chinese manufacturer of graphics cards Colorful, as the more well known in our region MSI, is preparing for the official announcement of Nvidia GeForce GTX 660 Ti card of alternative design iGame GTX 660 Ti ARES X. First of all, the eye catches a massive cooling system based on the Shark Bionic least five copper heat pipes and a pair of fan size ~ 80 mm.



According to the small heat release of GK104 chip in version with 1344 shaders, the efficiency of the cooler Shark Bionic is not doubtfull.


Card is equipped with (4+2)-phase power system and two connectors PCI-E Power 6-pin. In a similar version of Colorful GTX 670 there are six-channel power graphics core and two phases for the memory. Looking at the enclosed photo, is visible the presence of video outputs DVI (2), HDMI and DisplayPort connectors and a pair of SLI. What can not yet be explained, it is the presence of eight chips PCB Hynix GDDR5 — it is not combined with 192-bit bus.


Twelve pads for the RAM chips can …

XFX Teases Radeon HD 7990 Triple Dissipation Graphics Card

XFX has introduced its own version of Radeon HD 7990 — a top-tier graphics adapter from AMD. As distinct from the other companies that incorporated only some inconspicuous changes into their products, XFX has approached to the card’s modification with a violent zeal. As a result, today everyone has a chance of examining its Radeon HD 7990 Triple Dissipation card that employs two Tahiti XT GPUs, elaborated on Graphics Core next architecture.



Each Tahiti XT chip comes with 2048 stream processors and 3 GB of GDDR5 memory. This implies that the total memory capacity makes up 6 GB. GPUs run at 950 MHz clock frequency, but have the potential of achieving 1000 MHz frequency on overclocking. As for the memory, it employs 384-bit bus and runs at an efficient 6 GHz frequency.


To continue, all the components of Radeon HD 7990 Triple Dissipation are housed on an original PCB, designed by XFX. Connection with the PSU is realized via a pair of 8-contact power sockets. The rear …
