Detailed Specs

SAPPHIRE is tapping AMD's latest Vega 10 GPU which is made on the third-gen FinFET 14nm process, as well as the 8GB of next-gen HBM2 memory technology. There's additional overclocking headroom on the Limited Edition variants of the new SAPPHIRE RX Vega 64 NITRO+ graphics cards, something we'll be testing out later in the review.


We have 4096 stream processors alongside 64 NCUs powered by the Vega architecture, joined by 8GB of HBM2 memory and HBCC technology., he 8GB of HBM2 is on a 2048-bit memory bus.

The card itself is a 3-slot beast that requires 8+8+8-pin PCIe power connectors (yes, three 8-pin PCIe) and is pretty hefty at 310 x 133 x 54cm. There's a custom PCB with 14-phase VDDC, and SAPPHIRE's new enhanced TRI-X cooling and 'robust' VRM cooling.

Dual BIOS - NITRO Boost By Default

SAPPHIRE provides two BIOSes on the Radeon RX Vega 64 NITRO+ Limited Edition, with the NITRO+ Boost BIOS clocking the GPU at 1423/1611MHz for base and boost, respectively. The other efficient BIOS clocks the GPU down to 1273/1529MHz, which would be perfect for cryptocurrency mining as the card doesn't reduce HBM2 clocks down from 945MHz.
