AMD officially announced the Radeon RX Vega 56 Nano at Computex 2018 this year and its time we posted close-up shots of this tiny card. Nano editions have been pretty popular before and if the company is able to ship this in volume, this could be too.
Also, found a recent (4 days old) test article comparing my new Powercolor RX Vega 64 to the popular high end cards. Current tests are good because they use current GPU drivers -- which improve as time marches on.
In 18 game tests (9 at 2K and the same 9 at 4K), GTX 1080Ti wins all. My Powercolor RX Vega comes in 2'd in 15 out of the 18 tests. GTX1080 comes in 2'd in 3.
Thus, based on an independent test it meets my objectives for a very good gaming card. However, the FPS difference between my RX Vega and GTX1080 is very small.
Right now, Newegg has my card for $600 and the cheapest GTX1080 at $504 -- and, the cheapest comparable 3 Fan version of GTX1080 is $540. So, GTX1080 is the cost effective solution today.
