MSI GTX 1080 Gaming X 8G review – the dragon never sleeps

It was about time to jump in a new boat and NVIDIA made the step with their new Pascal architecture and the first two graphics cards based on it: GTX 1080 and GTX 1070. The first board was the reference version, but I know everyone was waiting for the custom solutions.

Today you can read the MSI GTX 1080 Gaming X 8G review. The card certainly looks interesting and it sports some new physical features.

Pascal – What’s new?

Nvidia brought a new architecture to the market: Pascal. This is used for GTX 1080 and GTX 1070 (for now) and of course will be present in future cards.

The news starts with 16nm FinFET fabrication technology of its 7.2 billion transistors. This should bring a better power efficiency and, of course, a higher performance level.

Pascal features 64 CUDA cores in a SM while Maxwell has 128, Kepler 192 and Fermi 32. It also has twice the amount of registers per CUDA compared to Maxwell.

It supports the HBM memory and the new GDDR5X. The 4th generation of Delta Color memory compression is present with Pascal with possible ratios of 4:1 and 8:1. Nvidia also introduced HDCP 2.2, which lacks in Maxwell.

Another interesting improvement is GPU Boost 3.0 that offers per voltage point frequency offset. That means the GPU scales frequency and voltage up, and it is possible to assign a clock offset to a certain voltage.  Basically it means that the card can overclock itself more efficient than Maxwell.
