New characteristics of co-processors Xeon Phi

For several years, developed Intel Larrabee graphics cards have changed its destiny, and now proudly referred to coprocessors Xeon Phi. The June announcement gave a very rough idea of ​​their characteristics and applications (highly specialized servers and workstations). Now some details will be revealed.



Bboosters Xeon Phi will be available in versions with 57, 60 and 61 core. There are in general 64 computational units, but some of them will be disabled. Depending on the number of cores the cache size varies from 1.8-1.9 MB first level and 28-30,5 MB second. The volume of onboard GDDR5 memory is 3, 6, and 8 GB.


Intel Xeon Phi device will operate on a low clock rate from 600-1100 MHz for the lower 57-core models with 3 and 6 GB of GDDR5, to the 630-1050 MHz or more for the older 60 — and 61-core board with 8 GB of RAM. Effective memory frequency will be in the range of 5-5.5 GHz. Support for dynamic overclocking Turbo Boost will be provided by reasonable balance of …

SSD Adata SX900 256 GB Review

The development of solid-state drives was intended to replace traditional HDDs and provide for faster speeds and better performance. Due to such outstanding parameters, SSDs were inaccessible for average customers, but violent growth of this market resulted in gradual decrease in prices. Nowadays 1GB costs less than $1(even with an advanced SATA 6Gb/sec interface), giving all audiences a chance to acquire high-end products for a reasonable price. Not all manufacturers manage to amaze users with their drives, but Adata, a Taiwanese PC hardware giant, always copes with this task. Its latest SSD model, SX900 256 GB, distinguishes itself from all rival products in terms of reliability, durability and performance.



Design and Integration


SSD series Adata SX900 is predestined to be installed in high-performance desktop and laptop systems, and will make benefit to all customers looking for an unbelievable efficiency of data storage subsystem. Model SX900 256 GB features 100x69x9.5 …

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 …
