OneXGPU 2 With AMD Radeon RX 7800M Crushes RTX 4070 Laptop GPU In 3DMark Time Spy

AMD's Radeon RX 7800M GPU in OneXGPU 2 turns out to be an impressive performer against the competition but its availability in laptops is still questionable.

The OneXGPU 2, revealed a few weeks ago, was again benchmarked in a synthetic test. If you aren't aware of OneXGPU 2, it's the external GPU solution for consoles and mini-PCs that comes with the Radeon RX 7800M GPU powered by RDNA 3 architecture and based on the Navi 32 silicon. This is the first eGPU to feature the RX 7800M, even before AMD's announcement, and the only product to feature the said GPU.

The OneXGPU 2 was tested in the 3DMark Time Spy benchmark published by One-Netbook itself.  The AMD Radeon RX 7800M scored a solid 15806 points in Time Spy graphics while delivering an overall score of 13456 points. OneXGPU 2 was hooked with the OneXPlayer X1 running on the AMD Ryzen 7 8840U APU, which is the low-power variant of the Ryzen 7 8840HS APU that will be used in the recently launched Acer Gaming Handheld, Nitro Blaze 2.

When compared to the AMD Radeon RX 7800M competitors from the green team, we find that it is roughly 28% faster than the RTX 4070 laptop GPU, which scores 12380 points. This is a quite big gap considering that the desktop variants of the RTX 4070 and RTX 7800 XT are roughly equivalent in raster performance.

Note: Scores are averages compiled by 3DMark.

It's well-known that the RTX 4070 laptop GPU is significantly nerfed compared to its desktop edition but this doesn't look like the case with the AMD Radeon RX 7800M.

Compared to the NVIDIA GeForce RTX 4080 laptop GPU, which scores 18927 points, the AMD Radeon RX 7800M is around 15% slower. The gap is roughly 2x smaller than the performance difference between the RX 7800M and RTX 4070 laptop GPU. It looks like the RX 7800M is a solid mobile GPU for playing modern titles as evident from the previous gaming benchmarks, where it was delivering 60+ fps in God of War 4 and RDR 2. 

The AMD Radeon RX 7800M GPU features 180W TDP, has 12GB GDDR6 VRAM on a 192-bit bus, and features 3840 Stream processors. As of now, this GPU is only available in OneXGPU 2 but the availability and pricing of the eGPU hasn't been revealed yet. We don't know if AMD has plans to introduce this GPU to gaming laptops but we do have the RX 7900M in some high-end offerings which might unfortunately be the case with the RX 7800M since it's announced in an eGPU solution and not a proper laptop.
