AMD Ryzen 9 9955HX vs Intel Arc G3 EXTREME Comparison

The AMD Ryzen 9 9955HX and Intel Arc G3 EXTREME are both active mobile processors, but they occupy entirely different tiers of the performance spectrum. The recorded data shows the Ryzen 9 9955HX winning all 15 head-to-head benchmark comparisons, with a dominant average benchmark score of 91,199 compared to the Intel part’s 36,699. The Ryzen 9 9955HX sits at the 96th percentile of all CPUs, while the Arc G3 EXTREME is at the 85th percentile. The Arc G3 EXTREME’s nearest rivals include the Intel Core Ultra 5 225 and AMD Ryzen 5 5600F, with score deltas of -0.6% and -0.7% respectively, indicating it is competitive with mainstream desktop parts. The Ryzen 9 9955HX, conversely, trades blows with high-end workstation silicon like the Intel Xeon 654 and AMD Ryzen AI Max+ 392, with deltas of 0.5% and 0.7%.

The Verdict

The data indicates a clear separation of purpose. The AMD Ryzen 9 9955HX is the choice for heavy multi-threaded workloads, professional content creation, and any task that scales with core count. Its 16 cores and 32 threads, combined with a 55 TDP, deliver results that place it among the top 4% of all recorded CPUs. The Intel Arc G3 EXTREME, with 14 cores and 14 threads at a 25 TDP, is a much more power-efficient part. Its performance class is defined by its nearest rivals, which are all mainstream desktop or mobile processors. It loses to the Ryzen by massive margins in nearly every test, with the smallest gap being a 2.3% deficit in single-thread performance.

For users who need maximum throughput, the Ryzen 9 9955HX is the only rational pick from this data. Its 153.6% lead in Cinebench R23 multi-core and 198.7% lead in PassMark integer math are insurmountable for the Intel part. The Arc G3 EXTREME is the pick only for scenarios where its lower power envelope is the primary concern, as its performance is closer to the AMD Ryzen 5 5600F and Intel Core Ultra 5 225 than to the Ryzen 9. The data does not support any scenario where the Intel processor can match the AMD part in raw speed. The Intel chip’s advantage, if any, is not visible in the recorded benchmark scores.
