Welcome the latest singleboard PC from Orange –Pi Prime, which can be called a successor of the last year's Orange Pi PC 2 model. Common peculiarities include the components layout and SoC Allwinner H5, possessing four Cortex A53 cores and Mali-450MP4 GPU.



Now DDR3 memory is doubled and equals to 2 GB. There is no eMMC module; and the microSD memory card of 64 GB capacity can be used for data storing. Audio and video interfaces are represented by the CEC-compliant HDMI 1.4, a composite port and a mic. The Gigabit Ethernet port is accompanied by the wireless module with support of Wi-Fi 802.11n and Bluetooth 4.0.


The specialty also features one micro USB and three USB 2.0 ports. Power can be supplied through USB or an appropriate connector from the 5 V, 2 A adapter Among other specs users can find a MIPI CSI connector, 40 outputs supporting Raspberry Pi, a three-pin UART, an IR-receiver, as well as a reset key and a power switch.


The approximate price of Orange Pi …

All graphics solutions represented in the market can be divided into three main groups: high-end cards that are destined for inveterate gamers and professionals, mainstream products for ordinary needs of average customers, and budgetary items for basic PC needs. Each of the segment is constantly replenishing with new products to satisfy the rising demands of consumers. Graphics solutions from Nvidia are widely represented in all three groups and enjoy popularity due to their advanced facilities. The company's latest adapter GTX 660 Ti doesn't have its own reference model, so each graphics card manufacturer is able to adjust it exactly to the individual model. Hence, Palit released its own card on the basis of Nvidia GTX 660 Ti adapter and codenamed it JetStream.



Integration


Palit GTX 660 Ti JetStream design is much alike the design implemented in Palit GTX 670 model. The new graphics card is based on a rather short circuit board that makes the cooling system unusually …

XFX has introduced its own version of Radeon HD 7990 — a top-tier graphics adapter from AMD. As distinct from the other companies that incorporated only some inconspicuous changes into their products, XFX has approached to the card’s modification with a violent zeal. As a result, today everyone has a chance of examining its Radeon HD 7990 Triple Dissipation card that employs two Tahiti XT GPUs, elaborated on Graphics Core next architecture.



Each Tahiti XT chip comes with 2048 stream processors and 3 GB of GDDR5 memory. This implies that the total memory capacity makes up 6 GB. GPUs run at 950 MHz clock frequency, but have the potential of achieving 1000 MHz frequency on overclocking. As for the memory, it employs 384-bit bus and runs at an efficient 6 GHz frequency.


To continue, all the components of Radeon HD 7990 Triple Dissipation are housed on an original PCB, designed by XFX. Connection with the PSU is realized via a pair of 8-contact power sockets. The rear …
