      ROCm 7.0.0 vs. ROCm 7.2.3 Performance On The AMD Radeon AI PRO R9700

      news.movim.eu / Phoronix • 14:20

    With the new System76 Thelio Major workstation review unit having arrived equipped with an AMD Radeon AI PRO R9700 graphics card, I took the opportunity of having the extra RDNA4 workstation GPU to satisfy a curiosity over whether there has been any meaningful performance gains from ROCm 7.0.0 released last year to now with the latest ROCm 7.2.3 stable release. Here are those benchmarks results if you are curious about the impact of just updating the user-space ROCm components from the end of last summer to the latest ROCm 7.2.3 milestone.
