OneXPlayer has revealed its plan to launch the OneXGPU 2, a new external graphics card solution based on the AMD Radeon RX 7800M. Alongside the announcement, the company also revealed 3DMark results for the unreleased mobile GPU, with the scores suggesting it is 28% faster than an RTX 4070 Laptop GPU.
The RX 7800M, as per previous announcements, is set to feature the RDNA 3 architecture with 3840 Stream Processors. While the GPU's configuration remains unchanged, it will deviate from the desktop version by utilising a 192-bit memory bus. Consequently, it will feature a memory configuration of 12 GB of GDDR6 VRAM. With a reported 180W TGP, the RX 7800M aligns with the power consumption of the flagship RX 7900M.
Recent testing done by OneXPlayer (via VideoCardz) of the new GPU involved pairing it with a gaming laptop equipped with a Ryzen 7 8840U processor. Utilising an OCuLink connection, the card scored 15,806 points in the 3DMark Time Spy graphics test, offering a basis for comparison with other GPUs. This initial test suggests that the RX 7800M could outperform the RTX 4070 Laptop GPU by 28%, although it is expected to fall short of the RTX 4080 Laptop GPU by 16%. Additionally, it notably outpaces the Navi 33-based RX 7600M XT by a substantial 83%, leading us to wonder if AMD will release a Radeon RX 7700M to fill in the gap.
OneXPlayer has yet to provide details regarding the availability of the new external GPU. AMD, too, has remained silent about the Radeon RX 7800M.

KitGuru says: Even if final performance isn't quite as good as these benchmarks suggest, it still looks like a capable discrete graphics card for gaming on-the-go.
