Introduction Sapphire PURE Radeon RX 7700 XT FP2

SAPPHIRE Technology, in collaboration with 11 bit Studios, developer of titles like This War of Mine and the Frostpunk series, has released the limited-edition SAPPHIRE PURE AMD Radeon RX 7700 XT Frostpunk 2 Edition graphics card. Designed for gamers, the card includes additional features such as enamel pins, keyboard keycaps, and a code for the Deluxe Edition of Frostpunk 2. Frostpunk 2, the sequel to the well-known city-building survival game, places players in a harsh, frozen world. In line with the game's aesthetic, the graphics card is equipped with a frosty-white fan shroud and a black metal backplate with rusty accents. An ARGB logo, set to Frostpunk 2's signature orange, provides a striking contrast. The lighting can be adjusted or disabled according to user preference.

The card is packaged in a custom Frostpunk 2-themed box and includes three enamel pins, three limited-edition keyboard keycaps, a keycap puller, and a Deluxe Edition code for Frostpunk 2. The RX 7700 XT PURE uses the Navi 32 silicon, a chiplet-based GPU that follows the design principles of the Navi 31, which is used in the RX 7900 series. The Navi 32 maintains a slightly reduced configuration and incorporates AMD's strategy of separating components that do not significantly benefit from a 5 nm manufacturing process. Instead, these components are placed onto 6 nm chiplets. Such components include the Infinity Cache and GDDR6 memory controllers, which reside on what are known as memory cache dies (MCDs). The MCDs house both a 16 MB segment of the Infinity Cache and a 64-bit segment of the 256-bit GDDR6 memory interface, while the core computational and graphics processing is handled by the 5 nm graphics compute die (GCD). Such features position the GPUs to notably influence the WQHD monitor resolution segment. However, premium performance comes with a price: the 7700 XT is priced at $449, while the 7800 XT begins at $499. For our review, we will be examining the Sapphire PURE Radeon RX 7700 XT FP2 edition. The Navi 32 variant, aka Radeon RX 7700 XT, sees a friendly 54 CU/3456 shader processor configuration, complemented by 12GB memory on a 192-bit bus running at an effective 18 Gbps data rate. This points towards a Navi 32 iteration with one of the four MCDs disabled, resulting in 48 MB of Infinity Cache. The core setup of the RX 7700 XT is anticipated to encompass approximately 54 Compute Units, housing a total of 3456 stream processors. Well, it's a GPU we all know in the year 2024.

The Sapphire Radeon RX 7700 XT Pure stands apart from its counterpart, the RX 7700 XT Pulse. The key distinction lies in the physical dimensions and cooling configuration. While the Pulse model features a 28 cm long cooler with two fans, the Pure extends to 32 cm in length and incorporates three fans. In terms of aesthetics, the card's paint job is defined by the cooler shroud, fan impellers, and backplate, while the PCB beneath remains black. Sapphire lists a ~$469 MSRP for the Pure variant, which is $20 higher than the base RX 7700 XT price. This price difference essentially accounts for the change in aesthetics, along with the inclusion of red lighting. Regarding the performance, the Pure model exhibits performance at our about the reference cards. It features a modest overclock and offers efficient cooling solutions. This makes it a viable choice for those seeking enhanced performance and thermal management without venturing into extravagant territory. Sapphire has chosen a clock frequency for the 'OC' SKU, peaking at 2584 MHz for its (dynamic) Boost clock frequency.
