AMD Mobile RDNA 4 Lineup Led by Radeon RX 9080M
AMD is preparing to launch as many as six new laptop discrete GPUs this Computex based on its latest RDNA 4 graphics architecture. The lineup will be built on its 4 nm "Navi 48" and "Navi 44" chips. It will be led by the Radeon RX 9080M, its new flagship part that maxes out the "Navi 48," enabling all 64 compute units for a core-configuration resembling that of the desktop RX 9070 XT. This rumor comes from AllTheWatts! on Twitter, a reliable source with AMD leaks. The RX 9080M gets 16 GB of memory across the chip's full 256-bit memory interface.
Positioned below the RX 9080M will be the RX 9070M XT, configured with 48 compute units for 3,072 stream processors, 96 AI accelerators, 48 RT accelerators, 192 TMUs, and possibly 96 ROPs. It gets 12 GB of memory across a 192-bit wide memory bus. This is essentially the same core-config as the upcoming desktop RX 9070 GRE. A rather huge notch below the RX 9070M, which is based on the physically smaller "Navi 44" silicon, and has 32 compute units for 2,048 stream processors, 64 AI accelerators, 32 RT accelerators, 128 TMUs, and 64 ROPs. This chip gets 8 GB of memory across a 128-bit memory bus.
