Ultra-fast flash: MSI GTX 1080 Ti Lightning Z in review

With the Lightning z, MSI really played with the muscles, which you also need as a customer when unpacking this chunk of graphics card. With a combat weight of just under 1.7 kilograms, the card competes to conquer the PCs of this world - the necessary K... MSI uses its own design for this board, which is also significantly different from the MSI GTX 1080 Ti Gaming X. The three 8-pin sockets for the external power supply are followed by three coils in the entrance area for smoothing the tips, as well as a s... Benchmarks in 2560 x 1440 pixels We have deliberately dispensed with Full HD (1920 x 1080p) as the MSI GTX 1080 Ti Lightning Z races into the CPU limit even in the highest settings. In WQHD (2560 x 1440 pixels), on the other hand, the actual work begins... Benchmarks in 3840 x 2160 pixels The MSI GTX 1080 Ti Lightning Z is between 9 and almost 12 percent faster than a GeForce GTX 1080 Ti Founders Edition, depending on the game, depending on the game. TitanX (Pascal). In total, v... Power consumption at different loads We measured the power consumption of the card in normal operation and at maximum overclocking. The normal power target of 300 watts can be manually increased up to 350 watts. That's what auc... Overclocking The overclocking with air cooling is terrific when you can withstand the fans working at 2500 rpm at maximum speed. But even so, the clock rates are the best we have ever done with an air-cooled ... Cooling system and backplate MSI has knocked on the new radiator and has not cracked, you can already put that in front of it. Somehow the fighting weight of almost 1.7 kilos has to pay off. Speaking of numbers, first of all the facts in practice... Summary It is almost a map of superlatives, because it is really fast, yet still sufficiently quiet and it still makes a lot of fun even with manual overclocking. Shock moments will probably only be experienced in the end two: the Pr...

MSI uses its own design for this board, which is also significantly different from the MSI GTX 1080 Ti Gaming X. The three 8-pin sockets for the external power supply are followed by three coils in the entrance area for smoothing the tips, as well as a shunt.

MSI relies on a design of 7+3 phases, doubling the 7 phases for the GPU. For example, two control circuits are available in parallel by 180° phase-shifted control circuits per phase. The three phases for the memory are to the right.

The back looks tidy and houses, among other things. PWM controller for memory.
