Well, when it comes to next-gen GPUs, AMD's CES 2025 presentation let us know that the Radeon RX 9070 and 9070 XT exist… and that's about it.
Unfortunately, we didn't hear any mention of specs or pricing—no CU counts and no info about VRAM or bus widths. However, Asus was the first to announce graphics cards featuring these RDNA 4 GPUs in the form of TUF OC and Prime OC variants, and what could have easily slipped under the radar is that these will have «a supersized 16GB serving of VRAM».
In other words, the first confirmation of 16 GB of VRAM for the RX 9070 and RX 9070 XT has come from Asus, not AMD. We've suspected we'd be dealing with 16 GB of VRAM since at least mid-2024 with some RDNA 4 GPU specs and performance rumours.
But as we said at the time, we couldn't trust those figures for certain, and AMD recently told us that «the performance data out there for RDNA 4 is completely inaccurate».
Nevertheless, the «16 GB of VRAM» part of previous rumours seems to have been correct. We don't know whether that'll be GDDR6 or GDDR7—though our money's on GDDR6—but the 16 GB pretty much says it'll be a 256-bit memory bus.
