Well, the crew went to work and boom, mission accomplished. They planted that 45 mm × 45 mm 2397-pin S-FCBGA chip with its 2688 shader/stream/CUDA processors onto a great PCB design, tucked 6 GB (24 pieces of 64M ×16 GDDR5 SDRAM) of memory (384-bit) on there and started designing a bunch of new tricks at BIOS and driver level.
I mention this specifically as the Geforce GTX Titan has been designed to overclock. The AIB partners will be allowed to offer voltage unlocked SKUs. And combined with GPU Boost 2.0 you will see this product boosting towards the 1100~1150 MHz range once you tweak it. The reference clock however is 836 MHz with a boost clock of 876 MHz.
However, tweaked... we got it running at 1176 MHz my man.
