Sapphire NITRO+ Radeon RX 9070 XT BIOS Leak Reveals "Navi 48 XTX" GPU Variant
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.
