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).

Review and testing of coolers GlacialTech Igloo H46 PWM and Igloo H58 PWM

The company GlacialTech Inc. known as a producer of cheap cooling systems aimed primarily at the lower and medium price segment. They are intended solely to cool the non-overclocked CPU. At the same time, GlacialTech has already made attempts to produce more efficient coolers that can cope with cooling of processors with high heat. It was the Siberia and Alaska, and F101 even before. Developing on its trend, the company has recently released two new models aimed at the medium price segment. It is about Igloo H46 PWM and Igloo H58 PWM.



Both coolers are available in the same decorated cardboard boxes, each on the right side shows the pictures of coolers and a list of supported platforms. On the other side of packaging there are specifications and key features of cooling systems. Packaging for both models are the same: it includes a steel universal clamping plate (backplate) with an adhesive base, two pairs of mounting with screws and key, two pairs of wire staples for installation …
