Nvidia Debuts with GeForce GTX 770 Graphics Adapter

Trailed by the flagship GeForce GTX 780 model, Nvidia officially launches one more high-performance graphics adapter of 700 series, codenamed GeForce GTX 770. Albeit the two products are rather similar in design (i.e. the incorporation of identical two-slot cooling system), their layout differs considerably. First of all, GTX 770 employs less efficient graphics core Nvidia GK104-425-A2 (28 nm) with 1536 CUDA cores, 128 TMUs, and 32 ROPs. At the same time this GPU operates at higher frequencies: 1046 MHz (nominal), 1085 MHz (dynamic).

Nvidia’s new entry comes either with 2 GB or 4 GB video memory modules of GDDR5 type. They employ 256-bit interface and ensure high bandwidth of 224 Gb/sec. Memory operational frequency is truly striking, demonstrating up to 1752 MHz (nominal) and up to 7010 MHz (dynamic) index. It should be noted that models with 4 GB modules will cost $50 more than those with 2 GB items (the recommended price makes up $399).

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 …

Zotac GeForce 640 GT: Kepler for $ 100

The emergence of a new GPU architecture does not only make records in the performance of high-end graphics cards, but often changes the idea of what to expect from an inexpensive card with a low TDP. Let see what can offer GT 640 — associate member of the family Kepler

The lower segment of the GeForce 600 is already fully staffed. In retail, there are cards GT 610, GT 620, GT 630 and GT 640, and in the OEM- channels additionally supplied GeForce 605. But among all of them, only GT 640 can be called a fully new model, since it is based on the architecture of Kepler, and the remaining cards are a familiar model series GeForce 400 and GeForce 500 Architecture (Fermi) with certain minor modifications.

GeForce 640 is based on the GK107 chip, which previously debuted in accelerators GeForce 640M. The performance of the last was comprehensively studied on the laptop Acer Aspire M3-581TG: compared to the GeForce 540M new chip provides a very nice speed boost. GK107 contains one …
