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).

AMD Officially Launches FreeSync Technology

The much-talked about graphical technology from AMD – FreeSync – is already out. Its privileges over rival solutions might be seen from different angles. To begin with, it dramatically optimizes the gameplay by improving image smoothness, reducing lag time, and eliminating splitting. FreeSync enables the synchronization of screen refresh time with GPU refresh time in real time; hence, images are updated only when the graphical adapter shapes the frame.

To continue, AMD FreeSync, is an open standard which does not require calculations, since it is integrated within an updated DisplayPort 1.2a interface. As distinct from Nvidia’s G-Sync, there is no need to equip the monitor with a dedicated module. Moreover, this technology supports the widest refresh range: 9-240 Hz; therefore, monitors manufacturers receive a tool for a standalone definition of operational limits for a particular model.

Currently, FreeSync is implemented within six graphics adapters and within …

APU AMD A10-4600M Review

Intel and AMD companies have established a good reputation for providing efficient hardware solutions for all customer groups. Each new product introduced by the two companies enters the top sales ranks and this promotes for the competition. AMD has recently produced a new APU solution based on Trinity architecture with graphics module VLIW4 and called it AMD A10-4600M. This model can boast the whole spectrum of improvements and advanced features as compared with its predecessor APU Llano, and is intended to beat its rival Intel in efficiency and performance.

Trinity Architecture

CPU Trinity is based on Piledriver micro architecture which superseded Bulldozer from AMD. The distinctive feature of Piledriver is that it’s primarily integrated in a mobile APU. Quad-core Trinity chips utilize two Bulldozer modules, each of which is equipped with two execution cores. Each APU module employs 2 MB of L2 cache, so the entire module architecture approximates to 4 MB of L2 cache; …
