Sparkle Computer, a Taiwanese supplier of graphics solutions and consumer electronics, has released two 3D graphics cards simultaneously. The two models have been codenamed Calibre X680 Captain and Calibre X670 Captain. Both cards are based on Nvidia GK104 GPUs developed under 28 nm standards. The chief peculiarity of the products is the integration of extraordinary cooler CoolPro; the uncommonness is seen in the localization of three fans that found their places under the radiator. This radiator is connected with the base, which is in direct touch with GPU, by means of six heat pipes.



Calibre X680 Captain and Calibre X670 Captain are equipped with DisplayPort, DVI, DVI-D, and HDMI video outputs. Graphics cards employ PCI Express 3.0 interface and support DirextX 11 interface, as well as, such Nvidia technologies as CUDA, PhysX, 3D Vision, and 3D Vision Surround. They are also notable for the availability of eight-phase voltage regulators and the enhanced depth of ground on the …

Wibtek, in cooperation with Foxconn, has launched a new all-in-one PC model with 21.5-inch display and Full HD resolution. The A21-TH61G-P model boasts the implementation of a wide spectrum of innovative concepts which allowed the developers to put all advanced functional commodities into a single attractive case to be applied in various corporate branches. Moreover, this PC offers a wide range of commercial applications and I/O interfaces that provide for an efficient use of work time.



Wibtek A21-TH61G-P is based on mighty Intel Core processors of the second and third generation that guarantee an unmatched multitasking. Such CPU model lines as i3, i5, i7, Pentium and Celeron are able to ensure high performance at a relatively low power-consumption. Graphics core with the central processor are integrated into a single chip; thus, they can easily cope with video processing without any suspensions. CPU resources are able to easily redistribute their facilities in correspondence …

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 …
