AMD Officially Introduces Radeon HD 7790 Graphics Card

An official introduction of a new graphics card from AMD, entitled Radeon HD 7790, has been settled into a dedicated press briefing. Within the framework of this briefing, the company not only gave a detailed description of a long-awaited product but also divulged a comparative performance analysis with its main rival’s adapter – Nvidia GeForce GTX 650 Ti. Therefore, AMD Radeon HD 7790 graphics card belongs to mainstream items and is targeting a wide range of customers. It is based on AMD Bonaire GPU with AMD GCN architecture developed under 28 nm technological process. The GPU consists of 896 current processors, 14 computing blocks, 56 texture blocks, and 16 ROP blocks.



Video memory subsystem comprises 1 GB of GDDR5 memory type, employing 128-bit bus. Its nominal clock frequency equals to 1500 MHz, while effective frequency makes up 6000 MHz. The overall efficiency level of this adapter is estimated at 1.79 TFLOPS; this index is twice larger than the one recorded with AMD …

SilverStone Showcases a Pair of New Add-Ons to the Strider Gold S Series

SilverStone has recently replenished its production lineup with a pair of new power supply units. Codenamed Strider Gold SST-ST75F-GS and SST85F-GS, the couple has entered the award-winning Strider Gold S series. As seen from the codenames, the units are estimated for 750 W and 850 W power correspondingly. Thanks to the incorporation of unprecedented features and some 90% efficiency, the products has picked up 80Plus Gold award.



The Strider Gold S new-comers feature a totally modular design and are developed in ATX form-factor. They are equipped with a single +12V bus. The latter is able to ensure the maximal performance for a gaming system, due to the maximal current of 62/70 A for the junior and senior models respectively.


It should be noted that SST-ST75F-GS and SST85F-GS correspond to all actual security standards. As a result, the units support voltage stabilization features (in the range of ± 3%), as well as vibration-proof and noise reduction features. This …

Plextor Debuts with M.2 6G Solid-State Drive

Plextor, an award-winning Japanese SSD designer, launches its another M.2 solution, codenamed 6G. This drive features 42 mm length only, fulfilling space requirements of small-sized but high-performance cases. The new-comer is available in two capacity variations: 64 GB (PX-64M6G-2242) and 128 GB (PX-128M6G-2242). Their retail price makes up $50 and $90 respectively.



Both Plextor M.2 6G solid-state drives come with PCI Express 2.0 interface. They are based on Marvell 88SS9188 controller and 19 nm MLC NAND flash-memory with Toggle interface (by Toshiba). The models support TRIM and NCQ technologies as well as DEVSLP power-efficient mode that reduces power consumption to 0.2 mW.


As far as speed characteristics are concerned, M.2 6G accelerate up to 520 Mb/sec on sequential Read operations; sequential Write index depends on the model: 160 Mb/sec for 64 GB model and 210 Mb/sec for 128 GB one. At the same time, random Read/Write operational index (4K blocks) makes up …
