Sapphire releases new Radeon RX 7800 XT/RX 7700 XT graphics cards
Following the footsteps of industry luminaries such as ASUS and ASRock, Sapphire recently unveiled their illustrious lineup of Radeon RX 7800 XT/RX 7700 XT NITRO+, PULSE and PURE series graphics cards. Within this collection, an ethereal “white color scheme” edition is anticipated, consisting of no fewer than six distinct variants.
The aesthetic design of the Radeon RX 7800 XT/RX 7700 XT NITRO+ bears a striking resemblance to the RX 7900 GRE. This design masterpiece incorporates a triumvirate of fans coupled with quintuple heat pipes for optimal cooling. This thermal module extends its benevolent protection over the video memory. Boasting a thickness spanning three slots, the card is further adorned with dual 8-pin power connectors, a sophisticated 14-phase VRM, and a meticulously layered 14-tier PCB. For enhanced user convenience, it offers a dual BIOS switching functionality and facilitates swift fan detachment. While Sapphire has maintained a veil of secrecy regarding the core frequencies, they have divulged a discernible rise in the TBP. Official specifications indicate that the RX 7800 XT’s TBP surpasses the reference model’s 263W by approximately 25W, while the RX 7700 XT exceeds its counterpart’s 245W by a marginal 7W, suggesting a probable augmentation in core frequencies.
The esteemed PULSE edition, in its grandeur, employs a dual fan setup complemented by quadruple heat pipes, encapsulated within a 2.5-slot thickness. Though core frequency details remain shrouded in mystery, official sources hint at a trifling 3W increment in the RX 7800 XT’s TBP, whereas the RX 7700 XT intriguingly witnesses a reduction, plummeting by 15W to a modest 230W. The rationale behind this remains an enigma.
The ethereal white color scheme variant, bearing the hallmark of a triple fan design, awaits official elucidation regarding its specifications. One can speculate its standing to oscillate between the NITRO+ and PULSE tiers.
The Radeon RX 7800 XT, powered by the robust Navi 32, possesses an arsenal of 60 CUs, translating to 3,840 stream processors. With an Infinity Cache of 64MB, it is complemented by a generous 16GB GDDR6 video memory, a 256-bit memory bandwidth, and a scintillating memory speed of 19.5 Gbps, all while maintaining a power consumption of 263W. In contrast, the Radeon RX 7700 XT, also fueled by the Navi 32, albeit in a streamlined form, houses 54 CUs, amounting to 3,456 stream processors. The Infinity Cache gracefully recedes to 48MB, paired with 12GB of video memory, a 192-bit memory bandwidth, and a memory velocity reduced to 18 Gbps, collectively drawing a power of 245W. Mirroring the precedent set by the Radeon RX 7000 series, each card is meticulously equipped with a DP 2.1 interface.
