In an event titled NVIDIA Editors Day 2017 in San Francisco, a graphics card that has been long awaited arrival finally announced officially. That is NVidia GeForce GTX 1080 Ti. This graphics card will replace the GeForce GTX 1080, and the class is intended for users who want high-performance enthusiast. The performance is 35% higher than the GTX 1080 reference specification, according to NVIDIA claims. In previous series or Graphic card built by NVidia, GTX 980 Ti is only 25% higher than the GTX 980 and GTX 780 Ti is only 18% higher than GTX 780.
The CUDA Cores Configuration in GTX 1080 Ti is quite interesting, because the same amount of Titan X Pascal (28SM, 3584 CUDA). In this case the difference is Titan X Pascal has a configuration memory with 384-bit bus width GDDR5X and 96 ROP units, while the 1080 GTX Ti only has a 352-bit, with 88 ROP units. NVIDIA has not given the GPU clockspeed details yet, but merely states that the GPU Boost clock would easily touch the 1.6 GHz (1582Mhz to be precise), and can reach 2 GHz with Overclock.
This clockspeed is able to make it even beat the Titan X Pascal. NVIDIA gave him the title of ‘The Ultimate GeForce’ because of the ability of the process is so fast. Configuration of memory bus GDDR5X with this unique number produces the amount of Video RAM 11GB, but running at speeds 10% higher than GDDR5X in GTX 1080. GTX 1080 and Titan X are equipped with a rating of 10Gbps GDDR5X (1250Mhz), whereas GDDR5X in GTX 1080 Ti uses a speed of 11 Gbps (1375Mhz).
This 11 Gbps is made possible by the use of GDDR5X with a high rating on Micron, and and some adjustment on the part of the PCB to allow high-speed IO, also fine tuning timing from NVIDIA. By that 11 Gbps rating in 352-bit bus, GTX 1080 Ti has theoretical memory bandwidth for about 484 GB/s. it is little bit higher than Titan X that has 480 GB/s.
The GTX 1080 Ti is equipped with 7-phase power regulator. By the rating of total 250A (35A per phase) and has been claimed to give high enough overclocking headroom, this card can be forced to run at its maximum limit. This GPU is also completed with cooler reference version that claimed to give cooling performance 5 degree of Celsius lower for the same noise rating.
