AMD Officially Introduces Radeon HD 7790 Graphics Card

An official introduction of a new graphics card from AMD, entitled Radeon HD 7790, has been settled into a dedicated press briefing. Within the framework of this briefing, the company not only gave a detailed description of a long-awaited product but also divulged a comparative performance analysis with its main rival’s adapter – Nvidia GeForce GTX 650 Ti. Therefore, AMD Radeon HD 7790 graphics card belongs to mainstream items and is targeting a wide range of customers. 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 …

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.


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 …

MSI Unveils New Gaming Graphics Card GeForce GTX 760 Hawk

MSI has recently introduced its newest graphics adapter with the support of Twin BIOS technology. Codenamed MSI GeForce GTX 760 Hawk, the card positions itself as an optimal solution for inveterate gamers, as well as for overclockers. The new-comer is based on Nvidia’s GK104 GPU (28 nm technological process) with 1152 CUDA cores. It runs on dynamically heightened frequencies, as compared with the reference model.

Therefore, the nominal clock frequency has been raised from 980 MHz to 1033 MHz, whereas the overclocked frequency has jumped from 1111 MHz to 1176 MHz. As for the memory, represented by 2 GB GDDR5 modules with 256-bit rail, its frequency index has not undergone any changes: 1502 MHz/6008 MHz (nominal/overclocked).

To continue, GTX 760 Hawk takes a fully modified 8-layer PCB as the basis. GPU power supply is ensured by means of an efficient power converter and prime-quality Military Class 4 components, including solid-state Hi-C CAP capacitors with tantalum …
