Days before releasing, Chinese leakers on Chiphell are showcasing a custom variant of AMD's upcoming Radeon RX 9070 XT with what appears to be a 12V-2x6 power connector. The custom AIB model is Sapphire Radeon RX 9070 XT NITRO+, which features a triple-fan cooling configuration and a departure from Sapphire's older GPUs that used eight-pin power connectors. Despite proving to be problematic for NVIDIA, this power connector could do well with AMD's Navi 48 XT GPU SKU due to its power consumption envelope. With an entire GPU projected to use 304 W total board power, the 12V-2x6 connector could easily power this configuration without the need to overheat and possibly melt. If it manages to power 600 W TGP NVIDIA GeForce RTX 5090, then powering a custom Radeon RX 9070 XT shouldn't be an issue.

Even if the card experiences a heavy overclock, power limits will remain within a usable range so as not to cause any trouble. Sapphire's reason for ditching the older, reliable eight-pin power connectors is unknown, but the use of the new 12V-2x6 here isn't expected to be problematic either. Some previous VBIOS records in our GPU DB indicate that the GPU could boost the Navi 48 XT SKU to 2,520/2,518 MHz, which is about 120 MHz higher than the stock AMD Radeon RX 9070 XT boost clock.

PowerColor's Radeon RX 9070 XT Hellhound model is a known property—in terms of its visual presentation—due to a public unveiling at CES 2025, as well as renders appearing online via official product pages. The Taiwanese manufacturer has decided to update its custom graphics card designs for AMD's incoming RDNA 4 generation—for example; the flagship Red Devil family is also refreshed for 2025. So far, PowerColor has showcased "standard black" Red Devil, Hellhound and Reaper designs. Rumors of additional Spectral White variants were circulating online earlier in the week.

Chinese market-exclusive PowerColor Radeon RX 7650 GRE Reaper models were launched very recently, complete with a Spectral White option. Following this official launch, VideoCardz picked up on inside track information; pointing to possible pale variants of forthcoming RDNA 4-based Red Devil cards. Days later, another PowerColor leak has unearthed an unannounced Spectral White SKU, albeit in Hellhound flavor. This product family usually offers a nice balance of high-end features and favorable pricing; we hope to see concrete details tomorrow. The leaked Hellhound card seems to feature an almost all-white aesthetic; extending to its PCB design and I/O bracket. No major surprises were disclosed in VideoCardz's report, but they noted a potential absence of RGB lighting zones. Previous-gen Hellhounds sport "fixed-color" schemes; enabling blue or purple lighting.

Sapphire's premium NITRO+ Radeon RX 9070 XT graphics card model was the subject of several leaks in the recent past—unsurprisingly, gaming GPU detectives gathered evidence of a very high speculative price point. The AIB's top "champagne gold" offering is due for a full unveiling; we expect to see examples tomorrow—AMD will broadcast a special Radeon RX 9070 Series presentation. Within the past 24 hours, VideoCardz received a compelling tip-off—the GPU news specialist was pointed in the direction of TechPowerUp. Currently, the site's VGA BIOS Collection hosts a downloadable "Sapphire 9070 XT 16 GB BIOS (Nitro+)" ROM.

The VGA BIOS build date is listed as "2024-12-13," with the file becoming available to download roughly two days ago (February 25). VideoCardz highlighted interesting "BIOS Internals" information; namely the mentioning of a "Navi48 XTX" GPU variant. Since CES 2025, AMD and its board partners have kept quiet about finer RDNA 4 details, but insiders and leakers have noted the existence of a generic "Navi 48" GPU. TechPowerUp's GPU database listings of AMD Radeon RX 9070 XT 16 GB and RX 9070 16 GB (non-XT) are freshly updated; reflecting new information sourced from pre-launch VGA BIOS listings. The incoming flagship seems to utilize a "Navi 48 XT" GPU variant (note: not 48 XTX), while its non-XT sibling is (supposedly) based on "Navi 48 XL." VideoCardz has heard whispers of a next-gen "Navi XTXH," industry moles have linked this sub-model to a supposed "higher-end" 32 GB RDNA 4 card. TPU's GPU database also alludes to an AMD Radeon RX 9060 XT GPU; just updated with a "Navi 48 LE" designation.
