The performance differences aren’t big but, like we've seen with Nvidia’s boost technology, the rated clocks aren’t much more than a rough guide of what to expect. The Sapphire Nitro+ and the ASRock RX 6800 XT Taichi X OC both share the same boost clock, yet the ASRock was able to hold about 20 to 30MHZ higher boost clocks consistently at roughly 2,350MHz vs 2,380MHz. The performance characteristics of RX 6800 XT cards appears to be at least partially dependent on the quality of the silicon itself. Storage - 1TB Samsung 860 Pro (OS), 1TB Western Digital SN750 Black (Games) Memory - 16GB Team T-Force Xtreem ARGB 3,600MHz It’s a neat addition and all of this results in the Sapphire being the quietest of the three non-reference RX 6800 XT cards we’ve reviewed so far.ĬPU - Intel Core i9-10900K 5.1 GHz all cores It has a large surface area thanks to its finned design. In addition to the beefy six heat pipe cooler, Sapphire has equipped a rather elaborate secondary heatsink to cool the memory and VRM. That extra cm or two over the longest RX 6800 XTs could be the difference between it fitting in a case, or not. The centre fan has a slightly smaller diameter, likely chosen in order to keep the card to a total length of 31cm. The outer shroud is plastic, though the backplate is metal. The design of the cooler is quite aggressive. There’s also an ARGB header if you want to synchronize other RGB devices with those of the card. If you’re after a good splash of RGB, you’re in luck thanks to an attractive RGB light bar and logo across the top of the card plus an additional graphic on the backplate. It lets you choose between both BIOSes with Sapphire’s Trixx software app. The card includes a dual BIOS feature, which includes an optional lower TDP setting in addition to the default one. Will it help with power limited OC? The PCB shares a lot in common with the reference PCB, but that’s because the AMD PCB is a good one, not that Sapphire is taking an easy option. Its 350W TDP is quite a bump over the 300W of the reference card. The PCB of the Nitro+ packs in a 13-phase VRM powered by dual 8-pin power connectors. If you want a little more bling, the Nitro+ SE sits above the Nitro+, which adds RGB fans and omits one of the DisplayPort sockets in favour of a USB Type-C port. The triple DisplayPort of the Nitro+ could make it a favourite of triple monitor users, especially those with higher resolution screens that have older refresh rate limited HDMI ports. The Nitro+ features standard black fans and three DisplayPort connections, plus a single HDMI 2.1 port. There’s a large cut out on the rear of the card to allow air to pass through it, not unlike the RTX 30-series Founder Edition coolers. Like most custom RX 6800 XTs, the Sapphire Nitro+ makes use of a large triple slot, triple fan cooler.
