SAPPHIRE NITRO+ RX Vega 56 Video Review: Big, Bold, and Unapologetic

It has been a long time coming, and still not the easiest of graphics cards to get your hands on, but we've had a bit of time to work with the SAPPHIRE NITRO+ Radeon RX Vega 56 Limited Edition.  In a previous video we took a detailed look at the card and what makes it different over something like the reference model, you can find it here.

 

But today we're digging into the full performance review with this new video.  We cover both stock out-of-the-box performance as well as optimized performance.  We didn't have time to go for full out overclocking results as well, but the tweaked performance seemed to be what most people were asking for. Don't worry, power draw figures are included, and rather surprising.

ETH and XMR Performance

Coin	-30% Core, 900MHz Memory, -15% Power Limit	Power Load From Wall
ETH	39.8 MH/s	281w
XMR	1300 H/s	280w

I know in our first video we showed the NITRO+ V56 mining ETH at more impressive numbers, but we found it to be unstable over time at those settings.
