The well-known in IT-maker Company MSI announced about appearance of new videoadapter based on GPU Tahiti XT chipset. Its diversity from the other Radeon HD 7970 can be seen with the naked eye, instead of an air cooler practically the entire surface of the PCB is covered with waterblock brand EK. It differs markedly from the original version, since it is designed specifically for the MSI R7970 Lightning model. Relation of adapter to the Lightning series is easily determined by the inscription at the interface connector PCI-E 3.0 x16, as well as non-standard set of video outputs (2x DVI, 4x Mini DisplayPort) and configuration of additional power connectors (2x PCI-E Power 8-pin).



Obviously, the accelerator is positioned as the Radeon HD 7970 GHz Edition and has a nominal frequency of at least 1050 MHz. Will MSI risk, like Sapphire did, and provide the card with 6 GB of memory? Probably not. The «advanced» composition of the printed circuit board and water block of full coverage …

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 …
