I think the VEGA 56 / 64 use AMD VCE for encoding & UVD for decoding... I have a RTX 2060 in a fast 6-core I7-9750H $999 Evoo 17 laptop & a VEGA 64 liquid-cooled in a faster 8-core 9900K desktop. The laptop renders faster than expected, 1:41 vs. 1:34 minutes on the 4K rendertest posted on these forums. HOWEVER, the VEGA 64 displays the same (complex) project in the preview window at max quality at 13.25 FPS vs. the RTX 2060's 7 FPS... The VEGA 56 has 3584 cores & VEGA 64, 4096 vs. the RTX 2060 with 2176 cores... The latest AMD drivers paired with the latest Intel iGPU drivers have provided my best performance yet...
