Sapphire RX 7800 XT Nitro+ Review: Big and Quiet

Posted on


The Sapphire RX 7800 XT Nitro+ takes the base Radeon RX 7800 XT and makes it better: better cooling, better performance, and better noise levels. It also adds some RGB lighting to brighten your day, and your PC, but bumps the price up over 10% compared to the reference design. The 7800 XT already ranks as one of the best graphics cards, and Sapphire improves on it in useful ways.

Here’s a rundown of the specifications, including other relevant GPUs.

Online Price $659 $500 $500 $550 $450 $390

First, let’s quickly talk about that price. Officially, Sapphire lists a $559 MSRP, $60 more than the base price. Currently, however, the lowest price we can find for the Nitro+ model is $659 at Amazon, via a third party reseller. Obviously, that’s way more than we’d suggest spending, but we’re going to assume that retail prices will shortly get down to more acceptable levels.

Otherwise, the main difference as usual comes from the change in boost clocks. The reference card has a 2,430 MHz boost, while the Nitro+ has a 2,565 MHz boost — 5.6% higher. The TBP (Total Board Power) for the Sapphire card is also higher at 288 watts, a 9.5% increase over the reference card’s 263W TBP. Those are just paper specifications, however, and as we’ll see on page four, real-world results can differ from those values.

Perhaps the bigger deal right now is that some of Nvidia’s board partners and retail outlets have dropped pricing on the RTX 4070 to $549, matching the Sapphire card’s nominal price. We don’t necessarily expect those deals to stick around for long, but pitting the RX 7800 XT, even in factory OC mode, against an RTX 4070 will make for a far tighter competition in raw performance, with Nvidia heavily favored in the efficiency and “proprietary extra stuff” departments — meaning DLSS upscaling, Frame Generation, and Ray Reconstruction.

AMD does provide more VRAM and bandwidth than Nvidia, with 16GB on a 256-bit interface. The best Nvidia can do is 12GB on a 192-bit interface, or alternatively 16GB on a 128-bit interface. The former comes from the RTX 4070 and represents a far better overall design than the RTX 4060 Ti 16GB, though AMD still has the edge in the memory department.
