Product Showcase

The 1080 Ti is based upon the GP102 graphics processor from Nvidia, it is a Pascal 16 nm FinFet architecture based GPU, and with 12 billion transistors, 3,584 shader/stream cores, and 11 GB of GDDR5X, it’s an impressive product series. In Ultra HD it can advance up-to becoming a true Ultra HD capable graphics card solution.

The GPU empowering it all is called the GP102-350-A1 GPU, which is Pascal architecture based. It has a nice 3,584 CUDA cores, while texture filtering is performed by 224 texture units. The reference (Founder Edition) cards have a base clock frequency of 1,480 MHz and perform texture filtering at 332 Gigatexels/sec. This Lightning clocks in at a default of 1,582 MHz, a 102 MHz higher clock frequency seen over reference.

The card has a 250 Watt TDP, 75 Watts is delivered though the PCIe slot, but then 150+150+150 Watts through the 3x 8-pin PEG (PCI Express graphics) power connectors, that means a board power design of 525 Watts. And yes, it is a heavy bloke at roughly one kg. That's plenty spare for a nice tweak but be aware that due to the clocks , the boost frequency already hovers around the 1,925 GHz marker.
 

 
Located at the top next to the two SLI fingers you will notice a small gap, if you use a tiny screwdriver or something, you can change the micro-switch. Basically this is the dual-bios - the card run default in its fastest OC mode, yet switch it and you will run LN2 mode. This LN2 mode will revert to reference clocks, but remove certain restrictions. We'll look at that in the overclocking segment though. 

At the backside of the PCB you'll notice three sets of pins, you can connect included wiring and then monitor the card mem/gpu/aux voltages with a Digital Multi-Meter, in fact let me show you that.

Here I am tapping the GDDR5X voltage rail, the memory should be working at 1.35v, as you can see it is at 1.37v for this factory clocked higher and tweakable memory.
