AMD Radeon RX 8000 “RDNA 4” Mobile GPUs to Feature Up to 16GB and 175W TGP in New Variants

The AMD Radeon RX 8000 “RDNA 4” mobile GPU lineup is on the horizon, promising impressive specifications tailored for high-performance laptops. According to leaked details from Golden Pig Upgrade Pack, AMD is expected to launch at least four mobile GPU variants in its upcoming Radeon RX 8000 series, aiming to set a new standard for portable gaming and creative applications.

AMD Prepares to Unveil Four Radeon RX 8000 “RDNA 4” Mobile GPUs

The lineup will reportedly include multiple SKUs, each designed to meet varying performance needs. The expected models include:

• R25M-E6 (Navi 48?) – 16GB, 256-bit bus
• R25M-E4 (Navi 48?) – 12GB, 192-bit bus
• R25M-P6 (Navi 44?) – 8GB, 128-bit bus
• R25M-P4 (Navi 44?) – 8GB, 128-bit bus

These mobile GPUs, designated by the “M” suffix, are anticipated to differ from their desktop counterparts, which use the “D” suffix. AMD’s mobile lineup will focus on delivering powerful yet efficient GPUs for laptops, with these models expected to debut with TGPs ranging from 50W to 175W, depending on the specific SKU.

Performance Specs and Expected Use Cases

The higher-end R25M-E6 and R25M-E4 SKUs are expected to replace the current Radeon RX 7900M and RX 7800M, both designed with 16GB and 12GB memory configurations, respectively. With a TGP of 80-175W, these GPUs are likely based on the Navi 48 architecture, with R25M-E6 utilizing the XT variant and R25M-E4 likely using the XL.

On the other hand, the R25M-P6 and R25M-P4 SKUs are expected to replace the entry-level RX 7600M XT and RX 7600M, built around the RDNA 3 Navi 33 architecture. These SKUs, with 8GB of memory and a 128-bit bus, will provide more affordable options for laptops while offering a TGP range of 50-150W.

Memory Speeds and Future Updates

While the memory speeds for the mobile RDNA 4 GPUs haven’t been fully confirmed, desktop variants in the RX 8000 series are expected to support memory speeds of 18, 19, and 20 Gbps using GDDR6 technology. Additionally, AMD may release a Navi 33 refresh for entry-level laptops, retaining the RDNA 3 architecture but potentially optimizing performance and efficiency.

Overall, these mobile GPUs are anticipated to closely align with the desktop versions expected to be unveiled at CES 2025, with a release targeted for Q1 2025.
