SAPPHIRE has revealed its selection for the Radeon RX 7800 XT and 7700 XT GPUs from AMD, comprising the PULSE, NITRO+, and the newly introduced PURE series.
Starting with the PURE series, it caters to enthusiasts who favor full-white builds and are also devoted SAPPHIRE fans. This series incorporates Tri-X Cooling Technology, complete with optimized composite heat pipes and an angular velocity fan equipped with dual ball bearings to maintain an optimal operating temperature.
Additionally, it boasts a 14-phase digital power system and conductive polymer aluminum capacitors for efficient power distribution to all card components. The PCB is constructed from high TG copper, and fuse protection safeguards the PCIe power cable from potential short circuits. The all-metal backplate and white finish, complemented by a simple red SAPPHIRE LED logo on the side, give the card a clean and aesthetically pleasing look at just 2.5 slots thick.
Moving on to the NITRO+ series, it shares several key features with the PURE series, including the cooling system, capacitors, all-metal backplate, and high TG copper PCB. Notably, the NITRO+ series features a V-shaped cooling module positioned atop the GPU die to ensure concentrated airflow. Meanwhile, the VRM cooling module targets the VRM for enhanced performance. T
he Cold Rolled Steel Frame adds durability to the frame, and it includes popular features such as the Quick Connect Fan, Assistive System Fan Control, Dual BIOS, and TriXX Software BIOS Switch. The series also includes an ARGB Light Bar and ARGB Backplate for vibrant lighting effects, and it comes with a GPU support bracket.
Lastly, the good old PULSE series adopts a dual-fan configuration with Dual-X Cooling Technology, featuring Intelligent Fan Control and Precision Fan Control capabilities. Similar to the other series, it utilizes a high TG copper PCB with optimized composite heat pipes and dual ball-bearing fans equipped with angular velocity fan blades for efficient heat control. Fuse protection is also included. The classic black and red PULSE aesthetics are still here to stay as usual.
Below is a simple table summarizing the primary clock differences among the three series:
| Model | Boost Clock | Game Clock |
| PURE Radeon RX 7800 XT | Up to 2475MHz | Up to 2169MHz |
| PURE Radeon RX 7700 XT | Up to 2584MHz | Up to 2226MHz |
| NITRO+ Radeon RX 7800 XT | Up to 2565MHz | Up to 2254MHz |
| NITRO+ Radeon RX 7700 XT | Up to 2599MHz | Up to 2276MHz |
| PULSE Radeon RX 7800 XT | Up to 2430MHz | Up to 2124MHz |
| PULSE Radeon RX 7700 XT | Up to 2544MHz | Up to 2171MHz |
