Excitement is in the air for tech enthusiasts as One-Netbook has unveiled the OneXGPU 2, the first external graphics card to feature the cutting-edge Radeon RX 7800M. This new GPU employs AMD’s RDNA 3 architecture and the Navi 32 silicon, making it a notable debut even before its official announcement.
The performance of the Radeon RX 7800M is already turning heads. In its first benchmark test using 3DMark Time Spy, the OneXGPU 2, equipped with the Radeon RX 7800M, achieved a score of 15,806 points. This score beats the Nvidia RTX 4070 Laptop GPU, which maxed out at 13,391 points in similar tests, making AMD’s new offering approximately 16% faster.
However, it’s important to understand that these impressive numbers come with a caveat. The OneXGPU 2 relies on an OCuLink connection, which can potentially reduce the GPU’s performance by up to 23%. If the Radeon RX 7800M were to be integrated into a laptop instead of an external setup, the benchmark scores would likely be even higher, further extending its lead over the Nvidia RTX 4070 Laptop GPU.
The scenario changes when we look at desktop variants. The desktop Radeon RX 7800 XT and the desktop RTX 4070 perform similarly in raster benchmarks. Comparing the desktop RX 7800 XT’s 3DMark Time Spy score of 20,147 points to the OneXGPU 2’s score reveals about a 24% difference in performance. This gap underscores the potential performance hit due to the OCuLink connection, suggesting that a direct laptop integration could elevate the RX 7800M’s capabilities significantly.
These findings indicate that gaming laptops equipped with the RX 7800M could offer a substantial performance boost over those using the RTX 4070. This revelation could lead to a shift in consumer preferences, as buyers seek the best performance for their money.
