Verdict

The Gigabyte GeForce GTX 1080 Ti Gaming OC is a high-performance graphics card built on the NVIDIA Pascal architecture, featuring 3,584 CUDA cores and 11GB of GDDR5X memory on a 352-bit bus. It operates with a boost clock of up to 1657 MHz in OC mode and utilizes the Windforce 3X cooling system with three unique blade fans and five composite copper heat pipes for thermal management. Key pros include its strong factory overclock, 4K gaming capabilities, and an 8+2 power phase design that enhances stability and overclocking potential. However, notable cons include the lack of a protective backplate, which can lead to PCB sagging, and reports of the cooling solution being noisier and less premium than higher-tier Aorus or competitor models.

En cabine • (on l'a fait) une GTX 1080 Ti sur un Core2Quad

This 2018 retro-hardware experiment by Le Comptoir du Hardware evaluates the performance bottlenecks of pairing a legacy Intel Core2Quad Q9650 processor (tested at stock 3.0 GHz and overclocked to 3.6 GHz) with a high-end Gigabyte GTX 1080 Ti Gaming OC graphics card. To isolate architectural limitations, the aging LGA775 platform (capped at 8GB of DDR2 6400 memory) was benchmarked...Read more
