Zotac GeForce 640 GT: Kepler for $ 100

The emergence of a new GPU architecture does not only make records in the performance of high-end graphics cards, but often changes the idea of what to expect from an inexpensive card with a low TDP. Let see what can offer GT 640 — associate member of the family Kepler



The lower segment of the GeForce 600 is already fully staffed. In retail, there are cards GT 610, GT 620, GT 630 and GT 640, and in the OEM- channels additionally supplied GeForce 605. But among all of them, only GT 640 can be called a fully new model, since it is based on the architecture of Kepler, and the remaining cards are a familiar model series GeForce 400 and GeForce 500 Architecture (Fermi) with certain minor modifications.


GeForce 640 is based on the GK107 chip, which previously debuted in accelerators GeForce 640M. The performance of the last was comprehensively studied on the laptop Acer Aspire M3-581TG: compared to the GeForce 540M new chip provides a very nice speed boost. GK107 contains one …

Greet Fractal Design Kelvin Liquid Coolers in Various Configurations

Fractal Design comes out with a new series of liquid coolers. The ‘Kelvin’ lineup is introduced by three models – T12, S24, S36 – which are differentiated by the amount of fans. The triple is targeting any up-to-date system based on Intel or AMD CPUs (Intel LGA 2011/1366/1150 and AMD FM2+/FM2/FM1/AM2+/AM2/AM3+/AM3). Their price is set at $99.99, $119.99 and $139.99 for one-fan, two-fan and three-fan model correspondingly.



Fractal Design Kelvin coolers boast an enclosed design that does not require additional maintenance during operation. They consist of a waterblock with a copper base, a powerful pump with a ceramic bearing, a copper heatspreader, and 1/2/3 Silent HP fans (of 120 mm dimensional type). The latter support PWM technology that adjusts rotational speed within 700-1700 PRM ranges; they are ready to produce up to 62.4 CFM airflow at 26.9 dB noise.


It should be noted that ‘Kelvin’ coolers might be expanded by new components. For instance, the T12 is …

Graphics Adapter Gigabyte GeForce GTX 650 Ti Boost with Modified Frequencies

Taking the lead from a number of Nvidia’s partners, Gigabyte has launched its own sample piece of GeForce GTX 650 Ti Boost graphics adapter. It is differentiated primarily by modified GPU and memory frequencies, as well as by an improved PCB design. The latter employs Ultra Durable 2 technology that stipulates the implementation of high-quality hardware components, including ferrite chokes, solid-state capacitors, and Low RDS Mosfets transistors with reduced resistance on mode changes.



Gigabyte GeForce GTX 650 Ti Boost is based on GK106 GPU, developed under 28 nm technological process. Its nominal frequency has been increased from the reference 980 MHz to 1033 MHz, while its dynamic frequency has been changed from 1032 MHz to 1098 MHz. This graphics adapter is furnished with 1 GB of GDDR5 memory, which clock frequencies have been, vice versa, lowered: nominal index dropped from 1502 MHz to 1250 MHz, dynamic index dropped from 6008 MHz to 5000 MHz.


This model employs …
