MSI GeForce GTX 770 Lightning comes with a non-reference PCB design that uses a GK104-425-A2 GPU core that is specified to have 1536 CUDA cores, 128 TMUs and 32 ROPs. It will be paired with 2GB of GDDR5 memory through a 256bit memory interface. Reference cards will be clocked at 1046MHz with an effective 1085MHz with boost while memory will be clocked at an effective 7GHz, giving the card the capabilities to perform much better than the current GTX 680 which is based on the same GPU architecture. However, this variant of GTX 770 Lightning will be expected to be factory overclocked at over 1100MHz out of the box.
Moreover, GTX 770 lightning from MSI will be making use of the latest Twin Frozr IV cooler, which is the latest and greatest flagship graphics cooling solution from MSI. This design utilizes two large 10cm PWM fans with Propeller Blade technology that aims to cool the card and vital electronic components on it as well. The cooler is made up of a high density fin grid array that provides heat dissipation from the GPU core through the heat-pipes which features MSI’s SuperPipe technology. The card also has dust removal features which cleverly allows the fans to run in reverse for 30 seconds after booting to remove dust from the heat sinks. Furthermore, this card is also beefed up with MSI’s GPU Reactor module that adds more power to the VRM, this increasing its overclocking potential and reducing static electrical noise.

4-Way SLI is supported on this card. However, this card requires 2×8-Pin Graphics card power connectors compared to dual 6-pin on the reference models. This is probably for extra power headroom when overclocking. It comes with Dual DVI, HDMI and display port output interfaces. The reference GeForce GTX 770 would cost 399USD-449USD at launch, and we can expect a much higher price point for this premium model.
