The adapter was tested on a Razer Blade 16 laptop with an AMD Ryzen AI 9 HX 370 processor and 32 GB DDR5 RAM. However, the results were significantly lower than expected.
The RTX 5090 laptop scored 91,063 points in Geekbench’s OpenCL test; this was less than half the RTX 4090’s average score of 190,680.
The main reason for this gap may be the limited operating frequency – only 1500 MHz, which is noticeably lower than the expected maximum. For comparison, the boost frequency of the RTX 4090 laptop is 2040 MHz.
Geekbench does not always accurately reflect the real performance of video cards, especially if the test is carried out in power saving mode.
Despite this, testing confirmed the RTX 5090’s key specs: 24GB of video memory and 10,496 CUDA cores distributed across 82 stream multiprocessors.
