Palit GeForce GTX 770 JetStream Specifications
GeForce GTX 770 was released more than a year ago as a gap filler between GeForce GTX 670 and GTX 780. While GTX 770 is considered a successor to GTX 670 it actually inherited all that previous flagship (GTX 680) could offer.
NVIDIA GeForce GTX 770 is essentially a higher-clocked GTX 680. It shares the same GPU specifications while offering much faster memory bandwidth. GTX 770 has GK104 GPU onboard with 1536 CUDA cores.
The core clock of Palit GTX 770 JetStream is set at 1150 MHz, which is 100 MHz more than reference model and almost 150 MHz over GTX 680.
The biggest change was introduced to memory configuration, as GTX 770 arrived with 1750 MHz modules. This increased the bandwidth to 224 GB/s from 192 GB/s (GTX 680).
Unlike GTX 780, the GTX 770 only offers 2GB GDDR5 memory. Although, you can buy 4GB models as well.

Palit GeForce GTX 770 JetStream closer look
The triple-fan JetStream cooler is made of plastic. While you probably expect higher quality materials for such a high-end graphics card, plastic actually makes this card very light. There are two metal decals with Palit and JetStream logos, but unfortunately I cannot say I’m a fan of how they look.
Physical specifications:
- Width: 132 mm
- Length: 294 mm
- Height: 2-slot
- Weight: 850 g
- Cooling: JetStream (triple-fan)
- Display outputs: DVI-D, DVI-I, HDMI, DisplayPort
The fan in the center is 92mm in diameter, while the two at each end are 80mm. The middle fan is not exactly placed right over the GPU, actually it’s where two large heat sinks are connected to each other with cooper heat pipes.
Palit GTX 770 JetStream is equipped with a fully custom PCB. It has 8+2 PWM phases, and more than enough for moderate overclocking. The PCB was originally designed with dual 8-pin power connectors, but the final version only has 6+8pin configuration.
Palit GeForce GTX 770 JetStream packaging
The bundle includes the driver CD, manual, dual 6-pin to 8pin converter, DVI to VGA and HDMI to DVI adapters.
