AMD Ryzen 3 3100U vs Intel Arc G3 Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison. The AMD Ryzen 3 3100U has a full set of PassMark benchmark results, while the Intel Arc G3 has no benchmark entries in the database. This means head-to-head comparisons rely entirely on the Ryzen 3 3100U's measured performance against its own nearest rivals, with the Arc G3's capabilities inferred from its architectural specifications rather than direct test scores.

The Ryzen 3 3100U delivers an average benchmark score of 6247, placing it in the 62nd percentile among all CPUs. Its nearest rivals in the database are all high-core-count desktop processors: the AMD Ryzen Threadripper 1950X scores 6231 (0.3% behind), the AMD EPYC 7272 scores 6186 (1% behind), the Intel Core i9-10920X scores 6347 (1.6% ahead), and the Intel Core i9-7940X scores 6147 (1.6% behind). These narrow deltas indicate the Ryzen 3 3100U, despite being a dual-core mobile chip, lands in a performance band comparable to much larger desktop parts in aggregate scoring.

Breaking down the Ryzen 3 3100U's individual benchmark results shows its strongest areas. The PassMark data compression test yields a score of 38455, a dominant result that far exceeds its other workload scores. Integer math scores 8873, floating point math reaches 5854, and extended instructions hit 2116. Random string sorting records 4666, while data encryption produces 1972. The single-thread score is 1592, and the multithread score is 3348. Physics simulation scores 232, and finding prime numbers scores 18.

The Intel Arc G3, by contrast, has no recorded benchmark scores, no average benchmark score, and no nearest rivals in the database. Its percentile ranking sits at 50, which is the median position, but this is based on zero measured results. The database shows no head-to-head benchmark entries and zero wins for either processor. Any performance comparison between these two parts must therefore rely on the Arc G3's specifications versus the Ryzen 3 3100U's measured results.

Where Each One Wins

The Ryzen 3 3100U wins every category where actual performance data exists, simply because it is the only part in this comparison with recorded benchmark results. Its data compression score of 38455 demonstrates substantial throughput in compression workloads. Its integer math score of 8873 and floating point score of 5854 show balanced arithmetic capability. The multithread score of 3348 with only 2 cores and 2 threads indicates efficient scaling, while the single-thread score of 1592 reflects per-core execution speed.

The Intel Arc G3 has no measured wins in the database. However, its specifications suggest areas where it could potentially outperform the Ryzen 3 3100U, based purely on architectural differences. The Arc G3 has 14 cores and 14 threads, a boost clock of 4.60 GHz compared to the Ryzen's 3.20 GHz, and a 25 W TDP versus 15 W. These figures indicate the Arc G3 is designed for higher sustained performance in multi-threaded workloads, should benchmark data eventually be recorded.

The Ryzen 3 3100U's wins in the existing data are clear: it delivers measurable performance in every tested category. The Arc G3's wins are speculative, based on core count and clock speed advantages that have not been verified through testing. In the database as it stands, the Ryzen 3 3100U is the only part with demonstrated performance, and it holds the win in every benchmark category.

Architecture Differences

The two processors come from fundamentally different design lineages. The AMD Ryzen 3 3100U uses the Picasso codename, belonging to the Ryzen 3 generation built on Zen+ architecture. It is manufactured on a 12 nm process at GlobalFoundries, with a die size of 210 mm² and 4,940 million transistors. The Intel Arc G3 uses the Panther Lake codename, belonging to the Arc G3 generation, built on a 3 nm process at Intel. Its transistor count and die size are not recorded in the database.

Core configurations differ sharply. The Ryzen 3 3100U has 2 cores and 2 threads, meaning no simultaneous multithreading. The Arc G3 has 14 cores and 14 threads, also without multithreading, but with 7 times the core count. Clock speeds show the Ryzen 3 3100U running at 1.90 GHz base and 3.20 GHz boost, while the Arc G3 runs at 1.90 GHz base and 4.60 GHz boost. The base clocks match exactly, but the Arc G3's boost clock is 1.40 GHz higher.

Cache hierarchies differ substantially. The 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 Arc G3 has 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3 cache. The Arc G3's per-core L1 is double, its per-core L2 is nearly 5 times larger, and its L3 is 4.5 times larger.

Memory support diverges completely. The Ryzen 3 3100U uses DDR4 memory on a dual-channel bus with 38.4 GB/s bandwidth. The Arc G3 uses LPDDR5X memory on a dual-channel bus with 136.5 GB/s bandwidth, which is 3.5 times the bandwidth of the Ryzen part. Neither supports ECC memory. PCIe connectivity differs as well: the Ryzen 3 3100U uses Gen 3, while the Arc G3 uses Gen 5 with 4 lanes for the CPU only.

Integrated graphics also differ. The Ryzen 3 3100U carries Radeon Vega 8 graphics, while the Arc G3 carries Arc B370 graphics. Both processors target the mobile market segment and have active production status. The Ryzen 3 3100U uses AMD Socket FP5, while the Arc G3 uses Intel BGA 2540. Neither has an unlocked multiplier.

The Verdict

The database records a complete benchmark profile for the AMD Ryzen 3 3100U but none for the Intel Arc G3. The Ryzen 3 3100U's average benchmark score of 6247 places it in the 62nd percentile of all CPUs, with nearest rivals like the Intel Core i9-10920X (6347, 1.6% ahead) and AMD Ryzen Threadripper 1950X (6231, 0.3% behind) showing it competes with much larger desktop processors in aggregate scoring. Its data compression result of 38455 is particularly strong, and its integer and floating point scores of 8873 and 5854 respectively show balanced arithmetic performance.

The Intel Arc G3 has no benchmark data, no average score, and no rivals in the database. Its specifications indicate a very different design: 14 cores, a 4.60 GHz boost clock, 18 MB of L3 cache, 136.5 GB/s memory bandwidth, and a 3 nm process. These figures suggest the Arc G3 is positioned for higher multi-threaded throughput and faster memory access than the Ryzen 3 3100U, but the absence of measured results means no verified performance claims can be made from the database.

For users relying on recorded data, the AMD Ryzen 3 3100U is the only processor with demonstrated performance across all benchmark categories. Its dual-core design delivers measurable results in compression, encryption, math, sorting, and single-threaded tasks. The Intel Arc G3, based on its specifications alone, appears designed for workloads that benefit from many cores, high boost clocks, and large caches, but its actual performance remains unrecorded. The choice depends on whether the user values verified results (Ryzen 3 3100U) or unverified but specification-heavy design (Arc G3). The data currently supports the Ryzen 3 3100U as the only part with proven performance.
