AMD plans to release six new laptop graphics cards at Computex based on the RDNA 4 architecture. These cards will use 4 nm "Navi 48" and "Navi 44" chips. The top model, Radeon RX 9080M, features all 64 compute units from "Navi 48" with 16 GB memory across a 256-bit interface.
The RX 9070M XT comes next with 48 compute units, 3,072 stream processors, 96 AI accelerators, 48 RT accelerators, 192 TMUs, and 12 GB memory on a 192-bit bus. A step down, the RX 9070M uses smaller "Navi 44" silicon with 32 compute units, 2,048 stream processors, 64 AI accelerators, 32 RT accelerators, 128 TMUs, 64 ROPs, and 8 GB memory on a 128-bit bus.
For thin laptops, AMD created the RX 9070S with the same specs as the RX 9070M but lower power limits. The RX...
