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).

To continue, GeForce GTX 770 …

The First Glimpse on NXP Signal Amplifier BGU8006

NXP Semiconductors company announces the release of a GPS signal amplifier BGU8006 destined primarily for the integration into mobile devices, tablets, navigators, photo- and video cameras. According to the words of the NXP representatives, their new model is the most bantam signal amplifier available in the market: BGU8006 dimensions equal to 0.65mm x 0.44mm x 0.2mm. Besides, this amplifier is characterized by the extremely low level of noise and the necessity to employ only a couple of external components to enable the device (decoupling capacitor and matching inductor).

The abundance of radio frequency signals serves the major impediment for the pure GPS signal reception. NXP BGU8006 has been developed with this thought in mind and is called to improve the reception of weak GPS signals by means of a dynamic rejection of strong signals released by the cellular and local wireless networks.

BGU8006 is based on QuBIC4Xi SiGe:C BiCMOS technology which is known to involve the …

Review of Motherboard Gigabyte GA-X79-UD5

The process of PC layout is quite delicate for the majority of people, since it depends on many factors, including requirements to the PC’s performance and customers’ financial possibilities. Motherboard selection is considered to be the most difficult stage in the process because it defines the basic functional characteristics of the computer. It should be stated that motherboards, which are attributed to the top line, show rather good functional but are frequently unaffordable. Quite the contrary, motherboards of the medium line are more preferable for people with average requirements and possibilities. Gigabyte GA-X79-UD5 falls under this category of motherboards and is a perfect alternative for customers with specific requirements and average wages.
