Gainward offers three models GeForce GTX 770, two hich characterized by reference frequencies - the GeForce GTX 770 Phantom 4GB and GeForce GTX 770 2GB. They differ, as we can see, by the volume of on-board memory and cooling systems. The first proprietary cooler Phantom II, and the second - a system with three fans. The most interesting is going to be the third card - GeForce GTX 770 Phantom Golden Sample 2GB with cooler Phantom 2013. The latter has a removable 3 fans , that can be easily removed and cleaned, including the surface of the board, and also the design of a copper base and five 8 mm heatpipes. This massive radiator dimensions are 98 x 273 mm, covering the components of the PWM control on the entire PCB.
Golden Sample - Gainward GTX 770 Phantom is factory overclocked, it is has 1536 cores and a frequency of 1202 MHz (1150 MHz - the frequency without overclocking, almost 10% increase over the standard clock frequency : reference 1046 MHz) and 2048 MB GDDR5 memory clocked at 3505 MHz bandwidth up to 224.3 GB / s.
There are differences in the power system of Gainward GTX 770 Phantom Golden Sample 2GB. The reference system NVIDIA GeForce GTX 770 has five phases. The unmodified versions Gainward uses 6 phases and proprietary PWM control system - DrMOS. But in the model Gainward GTX 770 Phantom Golden Sample 2GB implementation of 8-phase power supply.
Palit company - presented GeForce GTX 770 JetStream with its cooling system, which is armed with three fans.
To date, this decision will be a senior in the lineup Palit JetStream. The volume of on-board memory model is 2 GB GDDR5, factory overclock provide 10% of increase over the basic productivity at maximum graphics settings (factory frequency Palit JetStream identical to factory frequencies of Gainward GTX 770 Phantom Golden Sample - 1150/1202/710 MHz). The power system GeForce GTX 770 JetStream also contains 8 phase DrMOS. The fans in the cooling system - two 80-mm and one 90 mm with fan TurboFan Blade. According to Palit, the operating temperature is reduced by 15 degrees Celsius, while reducing the noise level by 9 dB. All this will allow the user to further overclock the adapter by another 5%.
