MSI has officially released its latest graphics card based on AMD’s 28nm Radeon HD 7970 GPU, the MSI R7970 Lightning. The MSI R7970 Lightning features 2048 Stream Processors, a 384-bit memory interface, a core clock of 1070MHz (1150MHz Boost Clock) and a 3GB of GDDR5 memory set @ 6000MHz. The MSI R7970 also sports all new unlocked Digital Power Architecture capable on unlocking BIOS, military class III components, an Enhanced Power Design to make overclocking better and faster, and a Digital PWM Controller.
The major problem in achieving high frequencies is heat, that’s why MSI employs the fourth generation Twin Frozr cooling solution: heatsink, a massive dual-fan cooler, which is more than capable of dissipating any heat thrown its way. Latest addition to the Lightning 7970 is an expansion board dubbed GPU Reactor — this promises cleaner power, which can be critical when squeezing that last few MHz out of a card. Furthermore, due to the increased width the GPU Reactor adds to the rear of the card, it has to be removed when the cards are placed in three or four-way CrossFire configurations.
The MSI R7970 Lightning has 1x DVI-D, 1x DVI-I and 4x mini DisplayPort outputs. The MSI R7970 Lightning BE sells for 55,000 Yen (about $697).
