AMD Ryzen 9 9955HX vs Intel Arc G3 Comparison

The Verdict

The benchmark database clearly separates these two mobile processors. The AMD Ryzen 9 9955HX delivers substantial multi-threaded and single-threaded performance, placing it in the 96th percentile of all CPUs tracked. The Intel Arc G3, by contrast, has no recorded benchmark scores in the database and sits at the 50th percentile, with an average benchmark score of zero. The data indicates that the Ryzen 9 9955HX is the choice for workloads that demand raw compute throughput, while the Arc G3 currently offers no measurable performance data to support any compute-oriented selection.

The Ryzen 9 9955HX shows a clear advantage in core count with 16 cores and 32 threads versus 14 cores and 14 threads on the Arc G3. The AMD part also carries a higher boost clock of 5.40 GHz compared to 4.60 GHz, and a higher base clock of 2.50 GHz versus 1.90 GHz. The TDP figures differ as well: the Ryzen runs at 55 W while the Arc G3 runs at 25 W. For applications that scale with thread count, the Ryzen 9 9955HX is the only part with data supporting such workloads. The Arc G3, lacking any scores, cannot be recommended for performance-sensitive tasks based on the recorded measurements.

The Intel Arc G3 does hold advantages in process node and memory bandwidth on paper. It uses a 3 nm process from Intel, while the Ryzen 9 9955HX uses a 4 nm process from TSMC. The Arc G3 also supports LPDDR5X memory with a bandwidth of 136.5 GB/s, exceeding the Ryzen's 89.6 GB/s with DDR5. These differences matter for memory-heavy workloads, but without benchmark scores for the Arc G3, the database cannot confirm any real-world benefit.

Architecture Differences

The Ryzen 9 9955HX belongs to the 9000 series and uses the Zen 5 architecture with the codename Fire Range. It is built on a 4 nm process at TSMC and contains 16,630 million transistors across a die size of 2x 70.6 mm². The Arc G3 uses the Panther Lake codename, belongs to the Arc G3 generation, and is built on Intel's 3 nm process. The database does not list a transistor count or die size for the Arc G3.

Cache configurations differ substantially. The Ryzen 9 9955HX provides 80 KB of L1 cache per core, 1 MB of L2 cache per core, and 64 MB of shared L3 cache. The Arc G3 provides 192 KB of L1 per core, 2.5 MB of L2 per core, and only 18 MB of shared L3. The Ryzen's larger L3 pool is notable for workloads that repeatedly access shared data across cores.

Memory support also differs. The Ryzen 9 9955HX uses DDR5 with a dual-channel bus and 89.6 GB/s of bandwidth, and it supports ECC memory. The Arc G3 uses LPDDR5X with a dual-channel bus and 136.5 GB/s of bandwidth, but it does not support ECC. The PCIe configurations differ too: the Ryzen provides 28 CPU lanes of Gen 5 PCIe, while the Arc G3 provides only 4 CPU lanes of Gen 5 PCIe.

Integrated graphics are another differentiator. The Ryzen 9 9955HX includes a Radeon 610M iGPU, while the Arc G3 includes an Arc B370 iGPU. The database does not provide iGPU benchmark scores for either part, so any comparison of graphics capability cannot be quantified here. The multiplier on the Ryzen 9 9955HX is unlocked, while the Arc G3's multiplier is locked.

The release dates place the Ryzen 9 9955HX in January 2025 and the Arc G3 in May 2026. Both parts are listed as active in production and both target the mobile market segment. The Ryzen 9 9955HX uses AMD Socket FL1, while the Arc G3 uses Intel BGA 2540.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between the AMD Ryzen 9 9955HX and the Intel Arc G3. The Arc G3 has an empty benchmark list, so no direct comparison scores exist. The Ryzen 9 9955HX, however, has a full set of recorded scores that establish its performance profile.

In Cinebench R23 multi-core, the Ryzen 9 9955HX scores 37,159. Its single-core score in the same test is 2,174. In Cinebench R15, the multi-core score is 5,905 and the single-core score is 336. These results indicate strong scaling across all 16 cores and 32 threads.

PassMark results for the Ryzen 9 9955HX show a multi-thread score of 56,171 and a single-thread score of 4,393. Integer math scores 212,598, while floating point math scores 136,682. Extended instructions score 57,946. Data compression scores 731,998, and data encryption scores 37,330. The find prime numbers test scores 287, random string sorting scores 77,890, and physics scores 2,720.

The Ryzen 9 9955HX has an average benchmark score of 91,199. Its nearest rivals in the database include the Intel Xeon 654 with an average score of 90,717, which is 0.5% behind, and the AMD Ryzen AI Max+ 392 with 90,541, which is 0.7% behind. The Intel Core Ultra 7 270K Plus scores 93,785, which is 2.8% ahead of the Ryzen, and the Intel Xeon 6520P also scores 93,786, also 2.8% ahead. These margins show the Ryzen 9 9955HX sits in a tight competitive band near the top of the database.

Because the Arc G3 has no scores, the head-to-head section cannot report any wins for either side. The wins counter in the database shows 0 for both processors. All performance analysis must therefore rely on the Ryzen 9 9955HX's recorded benchmarks and the architectural specifications of the Arc G3.

Where Each One Wins

The AMD Ryzen 9 9955HX wins in every category where the database has performance data. Its 96th percentile ranking, average benchmark score of 91,199, and extensive PassMark and Cinebench results give it a clear position for multi-threaded workloads such as rendering, compilation, and scientific computing. The 16-core, 32-thread configuration with a 64 MB L3 cache and 5.40 GHz boost clock supports both high core counts and high per-core speeds. The unlocked multiplier also allows frequency adjustment, which matters for users who can modify system settings.

The Intel Arc G3 wins in the specifications that require no benchmark confirmation. Its 3 nm process node is smaller than the Ryzen's 4 nm node, which indicates a more recent manufacturing technology. Its LPDDR5X memory support with 136.5 GB/s bandwidth exceeds the Ryzen's 89.6 GB/s, giving it a theoretical advantage in memory-bound tasks. The Arc G3 also provides more L1 cache per core (192 KB vs 80 KB) and more L2 cache per core (2.5 MB vs 1 MB), which could benefit per-core working sets. Its TDP of 25 W is less than half of the Ryzen's 55 W, suggesting lower power draw in constrained mobile chassis.

The Arc G3's integrated Arc B370 graphics may also offer a different visual compute profile than the Radeon 610M in the Ryzen, though the database records no iGPU scores for either. The Arc G3's 4 PCIe lanes limit expansion options, while the Ryzen's 28 lanes support far more direct CPU-attached devices. The Ryzen also supports ECC memory, which the Arc G3 does not, making the AMD part more suitable for data integrity-sensitive workloads.

In short, the data supports the Ryzen 9 9955HX for compute-heavy mobile workloads with measurable performance. The Arc G3 appears positioned for efficiency and memory bandwidth on a newer process, but the database contains no benchmark evidence to validate its performance claims.
