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).

Graphics Card Gigabyte GeForce GTX 680 Super Overclock Review

The launch of graphics solutions with WindForce 5X cooling system stirred a real boom in the market, giving a special tribute to the products developed by Gigabyte. The company launched two adapters this summer with the implementation of WindForce 5X system and now introduces one more card on its basis. Model Gigabyte GeForce GTX 680 Super Overclock can be called a paragon of efficient performance, overclocking and cooling activities.



Design


Graphics card GeForce GTX 680 Super Overclock features 295x120x64 mm dimensions and rather unusual design. Instead of common fans on the frontal board Gigabyte covered PCB and elements of cooling system by a metallic cover with decorative holes; the rear board is also covered by a metallic plate. The top board is only partially covered by the lid that hides a line of five fans, while the bottom board unveils a voluminous heatsink with heatpipes. The implemented circuit board is originally designed with a reinforced power supply …

EKWB Launches a New Water Block for GV-N680SO-2GD

Early August of 2012 was marked for Gigabyte by the release of its one more graphics card, codenamed GeForce GTX 680 SOC (GV-N680SO-2GD). This card can boast the availability of high factory frequencies and quite mighty cooling system. The nominal frequencies have been heightened to 1137MHz, 1202MHz, and 6200MHz for memory. Such outstanding characteristics required the integration of a high-quality and high-performance cooling system which consisted of five(!) fans. This made the card rather voluminous, cumbersome and noisy. That was when EKWB decided to design a dedicated water block to be employed with this remarkable graphics adapter.



Water block EK-FC 680 GTX SOC is housed on a copper base, good-quality acetal cover, and rubber shims as a compressor. The model is delivered with pre-installed fixing stands to facilitate the installation. It should be noted that this water block entirely covers the frontal part of the graphics card, along with the adjacent RAM modules and …
