MSI launched its GeForce GTX 780 Lightning flagship graphics card. Built from the ground-up with custom-design PCB and cooling, the card offers performance rivaled only by the more expensive GeForce GTX Titan.
It features out of the box clock speeds of 980 MHz core base, and 1033 MHz GPU Boost, compared to NVIDIA-reference speeds of 863 MHz base, 902 MHz GPU Boost. Memory is untouched at 6.00 GHz. It features 3 GB of GDDR5 memory across a 384-bit wide memory interface.
The GTX 780 Lightning features a 16+3 phase VRM that draws power from two 8-pin PCIe power connectors. An additional GPU Reactor module filters out electrical noise. The VRM uses high-grade chokes, PowIRstage driver-MOSFETs, and DirectFETs from International Rectifier, and tantalum capacitors.
The PCB is cooled by a unique new high-capacity air cooler by MSI, named TriFrozr. It uses large aluminum fin stack, to which heat is conducted by a number of 8 mm-thick heat pipes, which is then ventilated by a trio of fans, each with its own 4-pin connection to the PCB. You can control speeds of individual fans using Afterburner. The PCB also features voltage measurement points.
MSI is asking US $749.99 for the GTX 780 Lightning, a $100 premium over NVIDIA reference design.
