AMD Ryzen 3 3100U vs Intel Arc G3 EXTREME Comparison

The Verdict

The recorded data presents a decisive split between these two mobile processors. The AMD Ryzen 3 3100U and the Intel Arc G3 EXTREME occupy entirely different performance tiers, with the Intel part winning all 11 head-to-head benchmark comparisons. The Intel Arc G3 EXTREME holds an 85th percentile ranking among all CPUs in the database, while the AMD Ryzen 3 3100U sits at the 62nd percentile. The average benchmark score for the Intel chip is 36,699, compared to 6,247 for the AMD chip, a difference that places them in separate classes despite both being mobile parts.

The Intel Arc G3 EXTREME delivers its largest advantages in floating-point math, prime number finding, and encryption workloads, where its modern architecture and higher thread count produce multi-thousand-point leads. The AMD Ryzen 3 3100U, built on the older Picasso architecture, cannot close the gap in any measured test. For workloads that stress parallel execution, the Intel part is the clear choice. The AMD chip remains relevant only for scenarios where its lower power envelope matters more than raw throughput, but the benchmark data does not include any test where the AMD part wins.

The data suggests that buyers should select the Intel Arc G3 EXTREME for any compute-heavy mobile workload. The AMD Ryzen 3 3100U would only be appropriate for the most power-constrained designs, and even then, the performance deficit is substantial across every recorded metric.

Architecture Differences

The two processors come from different architectural eras. The AMD Ryzen 3 3100U uses the Picasso codename, built on a 12 nm process at GlobalFoundries, and belongs to the Zen+ (Picasso) generation. The Intel Arc G3 EXTREME uses the Panther Lake codename, built on a 3 nm process at Intel, and belongs to the Arc G3 (Panther Lake) generation. This process node difference, 12 nm versus 3 nm, explains much of the efficiency and performance gap.

Core counts differ dramatically. The AMD part has 2 cores and 2 threads, while the Intel part has 14 cores and 14 threads. Both have the same base clock of 1.90 GHz, but the boost clocks diverge: the AMD chip reaches 3.20 GHz, while the Intel chip boosts to 4.70 GHz. The Intel part also has a higher TDP at 25 watts, compared to 15 watts for the AMD part, which reflects its larger silicon budget.

Cache hierarchies show the architectural gulf. The AMD Ryzen 3 3100U has 96 KB of L1 cache per core, 512 KB of L2 per core, and 4 MB of shared L3 cache. The Intel Arc G3 EXTREME has 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3 cache. The transistor count for the AMD chip is 4,940 million on a 210 mm² die; the Intel chip has no recorded transistor or die size data.

Memory support also differs. The AMD part uses DDR4 with dual-channel support and a memory bandwidth of 38.4 GB/s. The Intel part uses LPDDR5X with dual-channel support and a memory bandwidth of 136.5 GB/s, a 3.5x bandwidth advantage. PCIe connectivity differs as well: the AMD chip uses Gen 3, while the Intel chip uses Gen 5 with 4 lanes for the CPU. The integrated graphics are also different, with the AMD part featuring Radeon Vega 8 and the Intel part featuring Arc B390.

Where Each One Wins

The head-to-head data shows no wins for the AMD Ryzen 3 3100U. Every recorded benchmark, from data compression to single-thread performance, goes to the Intel Arc G3 EXTREME. The Intel part wins all 11 comparisons, while the AMD part wins 0.

The Intel chip demonstrates its greatest strength in multi-threaded workloads. In floating-point math, it scores 86,929 versus 5,854 for the AMD chip, a 93.3% delta. In integer math, it scores 71,164 versus 8,873, a 87.5% delta. The multithread benchmark shows 30,659 versus 3,348, an 89.1% delta. These results indicate that the 14-core Intel part scales far better across parallel tasks than the 2-core AMD part.

The data also shows strong single-thread performance from the Intel chip. In the single-thread benchmark, it scores 4,293 versus 1,592, a 62.9% delta. This is the smallest percentage gap between the two, but still a comfortable lead. The extended instructions test shows 24,017 versus 2,116, a 91.2% delta, indicating the Intel architecture handles modern instruction sets more efficiently.

The AMD chip has no category where it leads. Even in the physics benchmark, which often favors lower-power parts, the Intel chip scores 2,515 versus 232, a 90.8% delta. The data does not support any use case where the AMD part outperforms the Intel part in measured performance.
