Which DDR3 SDRAM is better for Ivy Bridge

The overclocker memory is now in the category of products for perfectionists, still the common users are pleased with usual modules DDR3-1600 or DDR3-1333 SDRAM. The issue appears related to the release of processors Ivy Bridge series, which in some aspects are similar to its predecessors, still have some distinctive features.



Ivy Bridge processors are restricted on the maximum frequency supported by the DDR3 SDRAM. This indicates the theoretical chance of these processors work with high-speed memory DDR3-3200 SDRAM. Developers of overclocker memory package perceived the change in rules with certain enthusiasm: there are DDR3-2400 modules available in stores. The gap in frequencies of «elite» and «running» versions of the memory has grown twice in size. It won’t have a noteworthy blow on the work of commonly used tasks in systems.


The memory controller in the Ivy Bridge can work both in symmetric mode, with delay, frequency and volume modules in memory channels, and …

Nvidia GeForce GTX 780 Ti Graphics Card Official Release

After a line of rumors and leaks, Nvidia has officially introduced its latest powerful graphics card, codenamed GeForce GTX 780 Ti. Thanks to the implementation of a full-fledged GK110 core and the increase of clock frequencies, the card is going to compete with GTX Titan model, as well as with a top-tier Radeon R9 290X from AMD. In view of such efficiency, its recommended price goes up to $700.



The GeForce GTX 780 Ti is equipped with GK110 GPU that contains 2880 stream processors (GTX Titan features 2688 of them), 7.1 billion transistors, 48 ROPs, and 240 TMUs with the support for FP16/FP32 trilinear filtration. The core operates at 875 MHz (nominal) and 928 MHz (overclocked) frequencies. All major components are allocated on a black PCB, equipped with PCI Express 3.0 x16 bus. The incorporated GDDR5 modules with 384-bit interface (overall capacity – 3 GB) run at 7008 MHz with the bandwidth of 336 Gb/sec.


Power supply is realized via a single 8-pin and a single 6-pin …

Nvidia Intros Tesla K20X Graphics Accelerator

Nvidia introduces a new graphics accelerator Tesla K20X intended specifically for supercomputers. Tesla K20X, a flagship model of Tesla K20 series, is based on Nvidia Kepler architecture and is able to secure the highest performance supported by a single CPU. According to the preliminary testing, it ensures ten times faster operation of applications in combination with top-class processors. Moreover, this accelerator is currently supposed to be the most efficient one in the market, providing for utmost speeds and utmost performance ever seen.



Graphics accelerator Tesla K20X is notable by three times lower power consumption if compared with all previous generations of Nvidia products. Besides, it increases the performance discrepancy between GPU and CPU. A bunch of outstanding characteristics ensures 3.95 teraflops in calculations with a single precision and 1.31 teraflops in calculations with a dual precision.


In addition, a new series involves Tesla K20 accelerator that …
