Leaker Kepler_L2 has again detailed the AMD RDNA 5 AT2 GPU on the AnandTech forums: 70 compute units and target clocks between 3.1 GHz and 3.4 GHz. Combined, those figures would put the chip up to about 25% ahead of the Radeon RX 9070 XT on paper — before any architectural gains.
What happened?
According to Club386, OC3D, TweakTown and IT Home, Kepler_L2 restated on September 23, 2026 that AT2 should have 70 CUs. The RX 9070 XT, RDNA 4's flagship, has 64 CUs. That is six extra units, roughly 9.4% more width.
The same leaker cites 3.1 GHz to 3.4 GHz target clocks for RDNA 5. Versus about 2.97 GHz on the RX 9070 XT, that would be a 4% to 14% clock bump. Multiplying CUs and frequency, tech outlets estimate 14% to 25.1% more raw throughput — a hypothetical number, not a benchmark.
Why it matters
AT2 would not be a PC-only part. Reports tie the same silicon to Project Helix, the next Xbox, which would use 68 of the 70 CUs. If that holds, AMD would share a 2027 GPU between console and Radeon cards.
Kepler_L2 has also suggested AMD may ship only this new GPU in 2027, with the rest of RDNA 5 and NVIDIA's rival line slipping to 2028. That is roadmap rumor, not an official brief.
What changes in practice
Nothing changes today. AMD has not confirmed CUs, clocks, retail name or date. GDDR7 and ray-tracing or AI gains appear in parallel rumors, not in this specific leak post.
In practice the leak describes an incremental step, not a rupture: more units, higher clocks and possibly the same die on PC and Xbox. Anyone expecting a full-generation leap should wait for 2027 benchmarks.
