AMD Radeon RX 7900M Notebook CPU to Allegedly Be as Fast as the RTX 3090 in Gaming [Rumor]

AMD will focus more on the mobility segment with its next-gen RDNA 3 GPUs, with plans to launch a flagship as fast as the NVIDIA GeForce RTX 3090. While it’s unclear which graphics core it’ll leverage, I believe we’re looking at Navi 32 with quad memory dies and a moderately sized Graphics Compute Die (GCD). The 8,192 core (32 WGP) GPU will be paired with a 256-bit bus to a 12-16GB GDDR6 memory buffer. In addition, the Radeon RX 7900M will be backed by 96-128MB of L3 cache.

According to Greymon55, the Radeon RX 7900M will be as fast as the Radeon RX 6950 XT, the fastest desktop GPU AMD currently offers. Kopite7kimi reveals that it’ll also rival the RTX 3090, at least in terms of raster gaming performance.

AMD will likely unveil the Radeon RX 7900M and the remaining RDNA 3 mobile GPU at CES 2023 in January, but the hard launch should come much later, perhaps in the second half of 2023.

The Radeon RX 7900 XT will be unveiled on the 3rd of November, followed by the retail release in December. The rest of the Navi 3X SKUs should land in the following months, intensifying the battle in the GPU market as NVIDIA kickstarts its budget Lovelace offerings.
