New specification details for AMD's next-generation RDNA 5 "AT2" GPU have emerged from Kepler_L2 on the Anandtech forums, a leaker with a strong track record on AMD's roadmap. In a September 23 post, Kepler_L2 shared the new AT2 specs, which appear to be a significant step up from AMD's current flagship, the Radeon RX 9070 XT. An earlier post from the same leaker also said AT2 will be the only new GPU AMD or NVIDIA will sell in 2027, with the rest of both companies' next-gen releases delayed to 2028.
Looking at the specs, AT2 is reportedly built with 70 compute units, six more than the RX 9070 XT's 64, a 9.375% increase on paper. Kepler_L2 also claims that RDNA 5 targets clock speeds between 3.1 and 3.4GHz, which would be 4.3% to 14.4% higher than the RX 9070 XT, depending on the exact bin. Together, those increases put AT2 somewhere between 14% and 25.1% faster than the RX 9070 XT, and that's before AMD's rumored architectural improvements to ray tracing and AI workloads are even considered.

Microsoft's new and upcoming "Project Helix" console is also rumored to use 68 of 70 available AT2 compute units, closely linking the hardware to next-gen Xbox consoles and AMD's PC lineup. Separately, other leakers have reported that AT2's AI rendering hardware could reach RTX 5080-class performance, though that comes from a different leaker, expanding on Kepler_L2's numbers, and remains unconfirmed by AMD.

Unfortunately, AMD hasn't made any official claim about any of these leaks, and the name for the eventual retail card is still unknown, whether it launches as an RX 1070 XT or something completely different. But if these figures hold up, AT2 could be one of the most meaningful jumps AMD has delivered in years, and it would be performing largely alone in 2027 while the rest of the GPUs are delayed to 2028.
