AMD Launches 12 GB Radeon RX 7800M With The Same 60 Compute Units As The PS5 Pro & 7800 XT
AMD has officially introduced its Radeon RX 7800M mobility GPU featuring 60 Compute Units based on the RDNA 3 "Navi 32" silicon.
AMD's Radeon RX 7800M Packs Same 60 Compute Units As The PS5 Pro & 7800 XT, Equipped With 12 GB VRAM For High-End Gaming Laptops & More
AMD's Radeon RX 7800M is the latest addition to the red team's mobility RDNA 3 family which is aimed at high-end gaming laptops and other devices such as the OneXGPU 2, an external GPU solution that will be introduced next month on retail shelves. Although no laptop has been announced yet, we can expect the RX 7800M to see better availability across a selection of devices, something that the RX 7900M and even the mainstream 7600/7700(M/S) variants have lacked a lot.

Starting with the specifications, the AMD Radeon RX 7800M is based on the 5nm Navi 32 GPU silicon which incorporates the RDNA 3 GPU architecture. This chip comes with 30 WGPs and 60 Compute Units, making up a total of 3840 stream processors in a chip that packs 28.1 Billion transistors. The GPU also packs 96 ROPs and has a maximum texture fill rate of 560.4 GT/s and a peak FP32/FP16 performance rated at 35.87/71.73 TFLOPs.
This is the same core count as the AMD Radeon RX 7800 XT and the recently unveiled Sony PlayStation 5 Pro console. The former is based on the same Navi 32 silicon while the latter should be utilizing some enhancements found in the upcoming RDNA 4 architecture. As for the clock speeds, the chip has a maximum game frequency of 2145 MHz which is much lower than the 2430 MHz frequency of the 7800 XT and that's due to its TDP.
The TDP for the AMD Radeon RX 7800M GPU is rated at 180W while the 7800 XT has a 263W (+46%) higher TDP. The frequency difference is around -12% which should lead to lower performance.
The other major difference on the AMD Radeon RX 7800M GPU is its memory configuration
