It is based on AMD Bonaire GPU with AMD GCN architecture developed under 28 nm technological process. The GPU consists of 896 current processors, 14 computing blocks, 56 texture blocks, and 16 ROP blocks.



Video memory subsystem comprises 1 GB of GDDR5 memory type, employing 128-bit bus. Its nominal clock frequency equals to 1500 MHz, while effective frequency makes up 6000 MHz. The overall efficiency level of this adapter is estimated at 1.79 TFLOPS; this index is twice larger than the one recorded with AMD …

Radeon HD 7990: postponed, can not be executed

Nvidia's half hearted established the supply of dual-chipset videoadapter GeForce GTX 690. In turn, the competing Radeon HD 7990 is seriously delayed, although previously the release for late July was planned.

Gigabyte Showcases GTX 1080 Xtreme Gaming WaterForce WB 8G Video Card

Gigabyte has developed a video card, based on Nvidia GeForce GTX 1080 adapter, which provides for freedom in choosing the liquid cooling system with an open contour. The GeForce GTX 1080 Xtreme Gaming WaterForce WB 8G comes with a pre-installed water block that entirely covers the frontal part, enhancing the cooling effect on the GPU, power elements as well as memory chips. In order to achieve the maximal heat dissipation performance, the user just needs to connect the card to the liquid cooler contour.



Gigabyte GeForce GTX 1080 Xtreme Gaming WaterForce WB 8G takes Nvidia GP104-400 GPU as the basis (Pascal micro-architecture). The GPU consists of 2560 CUDA, 160 TMUs & 64 ROPs. The model is able to operate in two modes: OC and Gaming. In OC mode the core runs at 1784/1936 MHz frequency (basic/dynamic), while in Gaming mode the showings are more modest: 1759/1898 MHz frequency.


To continue, the GPU is accompanied by 8 GB of GDDR5X memory (256-bit interface) which operates at …
