Sapphire Radeon RX 7900 XTX Nitro+ Review
The fastest XTX of all?

Sapphire is back with the NITRO+ RX 7900 XT, a high-performance graphics card with a beautiful minimalist design, excellent cooling and a solid 20-phase power system distributed on a 14-layer High TG PCB with 2 oz of copper . It’s a card that’s been tweaked pretty well, with a 2680 Boost frequency and 420 TBP / 340W TGP, it’ll be faster than its competition. These massive 3-slot parts are able to bump their clock speed up a notch over the reference design. We were surprised to see that this product is equipped with three 8-pin power inputs. No custom SKUs have been released with a USB Type-C port, and the ASUS TUG is no exception. Instead of multiple HDMI ports, gamers will have three DisplayPort ports and a single HDMI. We’ll cover that in our tweaking segment of the article – we’ve got the flagship Radeon RX 7900 GPU inside the XTX, which uses the latest rDNA3 GPU architecture and has 24GB of graphics memory. When tested against the GeForce RTX 4080, the card holds up. You get a whopping 24GB GDDR6 memory, the same as the RTX 4090, at a much lower cost. Clock speed, however, is a bit of a hassle, as we’ll explore in more detail below. Currently, memory capacity is the most crucial metric to highlight. Despite using 24GB of memory like Nvidia’s current flagship RTX 4090, AMD’s RX 7900 XTX uses slower GDDR6 memory. Faster memory rates are generally better. However, this is not always the case. Due to the RX 7900 XTX’s huge 384-bit memory bus, the card’s memory isn’t as fast as other options and has more bandwidth thanks to an infinity cache. Two cards are released for the initial launch: the 7900XT and 7900 XTX. Both are based on the Navi 31 GPU, which has an RDNA3 architecture and is based on a new chip design. Yeah, chiplets man, and it’s a big GPU, okay. The die area of ​​the Navi 31 GPU chip is 300mm2. AMD has confirmed that its RDNA 3 graphics processing units (GPUs) have a huge performance boost. AMD will highlight some of the essential parts of RDNA 3 GPUs, such as:

	Radeon RX 7900 XTX	Radeon RX 7900 XT
Architecture	5nm RDNA3	5nm RDNA3
GPUs	Navi 31 XTX	Navi 31 XT
shader processors	12288/6144SP	10752/5376SP

Memory bus	384 bit	320 bit
Memory speed	20 Gbps	20 Gbps
Infinite cache	96 MB	80 MB
Bandwidth	960 GB/s	800 GB/s
PAD	355W	300W
Price	$999	$899

The RDNA3 NITRO+ has been revisited from top to bottom by the firm. The new Nitro+ has a silver shroud and backplate, giving it a very contemporary look. A closer look at the new images reveals that the RX 7900 XTX NITRO+ is only slightly larger than three slots. Both sides of the board have large ARGB LED strips that can be independently adjusted using the Sapphire TRIXX app. Additionally, an RGB connector is available for home users who prefer to coordinate their lighting with other devices. Additionally, like the NITRO and NITRO PURE series, the Sapphire RX 7900 XTX will provide a dual-BIOS switch. The NITRO+ has a unique I/O layout and three 8-pin power connectors. Unlike AMD’s MBA cards, this one only has two HDMI 2.1 connectors and two DisplayPort 2.1 ports. It appears to be the first card of its kind to include two DisplayPort connectors. AMD promotes a 2.3 GHz gaming clock for the RX 7900 XTX, which is the speed at which you can expect the card to run while playing games. However, Sapphire defaults to this value at around 2.51 GHz, with 2680 MHz for the boost clock on a 339 W TGP. Admittedly, these are fairly minor improvements, but every little bit counts. The Nitro+ cards have three 8-pin PCIe power ports instead of two, and the rear USB Type-C port has been removed, making them noticeably different from AMD’s reference design above. beyond their obviously larger dimensions. The NITRO brand guarantees high quality components and robust construction, such as a sturdy die-cast frame in which the aluminum backplate and shroud have been cast for added strength. In order to dissipate heat more efficiently, the new cooling design uses three fans to propel more airflow around the edge of the backplate. The card defaults to performance mode which brings 5% sometimes 6% more performance compared to reference cards. The Radeon RX 7900 XTX will use standard 8-pin PCIe connectors rather than the 12VHPWR splitter port and, as noted, will require three.
