Sapphire Radeon RX 7800 XT, RX 7700 XT NITRO and PULSE series
The company is preparing at least six models.
Sapphire’s flagship tier, known as NITRO+, will consist of two models, one for each SKU. These cards feature a robust 3-slot design with a triple axial cooling solution. They come equipped with dual 8-pin power connectors, a 14-phase VRM, and a 14-layer PCB design. The cards boast a large heatsink connected to 8 heatpipes, along with dedicated cooling for the memory modules.
The NITRO+ series will offer a dual-BIOS feature, fuse protection, and fan headers for users who wish to synchronize the GPU and chassis fans.
Sapphire has not yet disclosed the clock speeds for its new Navi 32 GPUs. However, it has been confirmed that NITRO+ models will come with a higher TBP (Total Board Power) right out of the box. The RX 7800 XT is expected to have a 288W TBP (+25W), while the RX 7700 XT will be configured with a 252W TBP (+7W).
The RX 7800/7700 PULSE series will incorporate a dual-fan cooling solution, requiring a 2.5-slot space on the motherboard. Unlike the NITRO series, these cards will lack the dual-BIOS feature and won’t include any LED illuminated elements. As per the official spec sheet, the RX 7800 XT is expected to have a 266W TBP (+3W), while the RX 7700 XT is listed with a 230W (-15W) TBP, which seems to be an error on the website, but it’s what Sapphire has presented.
Similarly to the NITRO+ series, there are no specific clock speeds mentioned. However, the cooling renders seem to suggest that both NITRO and PULSE may share the same PCB layout, albeit with minor modifications.
Finally, Sapphire has introduced its PURE series; however, the company has not yet updated its website with information about these cards. Based on the renders, this model could potentially feature either a 2-slot or 2.5-slot design and will employ fans similar to those found in the NITRO+ series, albeit with a wholly different white color scheme. The PURE series is expected to occupy a position between the NITRO+ and PULSE series in terms of performance and pricing, but these details are still pending confirmation from the company.
