Graphics Card Sapphire Toxic HD 7970 GHz Edition Review

Up-to-date facilities provided by graphics cards manufacturers allow customers to create various graphic configurations, including the activation of several monitors within a single card. Indeed, contemporary technical approaches transform traditional video adapters into video gurus. The latest development of Sapphire, a flagship model Toxic HD 7970 GHz Edition, offers up to 6 GB of GDDR5 memory and promotes for the activation of six monitors in Eyefinity. Such options exceed those integrated into a reference model, AMD Radeon HD 7970 GHz Edition, and are able to ensure a dramatic increase in performance.



Technical Peculiarities


Sapphire decided to base its flagship model on GPU AMD Tahiti with an integrated delimiter which lowers the clock frequency on the overshoot of thermal threshold. Its standard frequency equals to 1050 MHz, nominal frequency – 1100 MHz; sill, this GPU features Lethal Boost options that increase the frequencies up to 1200 MHz. This graphics card is …

The Switchover to Nvidia GeForce GTX 760

Nvidia has officially introduced one more graphics adapter from 700 series: GeForce GTX 760. As it was expected earlier, the card is based on GK104 graphics chip (on Kepler architecture) with 1152 CUDA cores, 32 ROPs and 96 TMUs. Its nominal clock frequency makes up 980 MHz, still this index might be overclocked at average to 1033 MHz.



Reference adapter is furnished with 2 GB of GDDR5 memory that employs 256-bit interface. Nonetheless, Nvidia does not exclude the possibility of introducing the models with 4 GB memory capacity. The nominal memory clock frequency equals to 1502 MHz, while its overclocked frequency reaches up 6008 MHz. This adapter is thought to support GPU Boost 2.0 technology that adjusts the overclocking frequency in reliance on GPU thermal condition. Thus, the more powerful cooling system is, the higher frequencies the users might expect.


To continue, power supply subsystem is represented by a couple of 6-contact power sockets. The maximal claimed TDP …

The official announcement of the motherboard Biostar Hi-Fi Z77X

Company Biostar, taking the example of the motherboard market leaders, manufactures the product for the audiophile — Biostar Hi-Fi Z77X. In the latest model are involved: the processor socket LGA1155, the flagship chipset for the platform (Intel Z77), three full-height PCI Express x16 and 13-channel subsystem of CPU power. The developer promises high quality audio through 7.1-channel HD Blue-ray audio codec ALC898, Technology THX TruStudio Pro, Hi-Fi Ground (multi-layer PCB with protectors properties), and Puro Tone (signal / noise ratio — 110 dB), as well as resistors, Hi-Fi Resistor with tin oxide capacitors and Hi-Fi Cap.



Four slots for memory with dual access are designed for installation of modules DDR3-1066/.../2600 totaling 32 GB. In addition, the construction of SLI and CrossFire configurations using the formula «x8 + x8» is possible. The lower slot PCI-E 2.0 x16 x4 is good to use for high-speed SSD-drives, and «external» controllers. PCB has six ports Serial ATA …
