Architecture Differences

The AMD Ryzen 7 PRO 8840HS and the Intel Arc G3 represent fundamentally different architectural approaches. The AMD chip uses the Zen 4 architecture under the Hawk Point codename, manufactured on a 4 nm process at TSMC. The Intel chip uses the Panther Lake codename with a 3 nm process at Intel's own foundry. The process node difference gives Intel a manufacturing advantage, but the architectural designs diverge significantly.

The Ryzen 7 PRO 8840HS is a traditional high-performance mobile CPU with 8 cores and 16 threads, relying on simultaneous multithreading to double its thread count. Its cache hierarchy is organized as 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. This design prioritizes single-threaded responsiveness and balanced multi-threaded workloads.

The Intel Arc G3 instead uses 14 cores and 14 threads, indicating a hybrid architecture without hyper-threading on any core class. Its cache structure is substantially larger per core: 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 18 MB of shared L3 cache. This suggests the Intel design favors high-bandwidth, multi-core throughput with larger per-core resources.

The memory controllers also differ. The AMD chip supports DDR5 with dual-channel access, delivering 89.6 GB/s of bandwidth. The Intel chip uses LPDDR5X with dual-channel access, achieving 136.5 GB/s. The Intel part also has ECC disabled, while the AMD part includes ECC support. PCIe connectivity differs as well: the AMD chip provides Gen 4 with 20 CPU lanes, while the Intel chip provides Gen 5 with 4 CPU lanes. The integrated graphics units are distinct, with Radeon 780M on the AMD side and Arc B370 on the Intel side.

The transistor count and die size are only specified for the AMD chip: 25,000 million transistors on a 178 mm² die. No comparable data exists for the Intel part in the database.

Where Each One Wins

The recorded data shows a clear performance split based on workload type. The AMD Ryzen 7 PRO 8840HS has an extensive set of benchmark scores, while the Intel Arc G3 has no recorded benchmark results. This means the AMD chip wins all 15 recorded benchmark comparisons by default, but the qualitative strengths suggest where each would excel.

The AMD chip's strength lies in its high boost clock of 5.10 GHz and Zen 4 architecture, which typically favors lightly threaded tasks. Its 16 threads provide solid multi-threading capability for productivity workloads. The Radeon 780M integrated graphics can handle general-purpose visual tasks.

The Intel Arc G3's advantages are structural rather than measured. Its 14 cores and 18 MB of shared L3 cache suggest strong multi-core throughput potential. The 136.5 GB/s memory bandwidth is a significant edge for memory-intensive workloads like data compression or encryption. The 3 nm process node indicates better power efficiency potential at lower clocks.

The AMD part's 28 W TDP is slightly higher than the Intel part's 25 W TDP, which is a narrow margin. The Intel chip's lower TDP combined with a smaller process node could make it more efficient in thermally constrained chassis.

Specification Differences

The two processors differ across nearly every specification field. The AMD Ryzen 7 PRO 8840HS uses 8 cores and 16 threads, while the Intel Arc G3 uses 14 cores and 14 threads. Base clocks are 3.30 GHz for AMD and 1.90 GHz for Intel. Boost clocks are 5.10 GHz for AMD and 4.60 GHz for Intel. TDP ratings are 28 W for AMD and 25 W for Intel.

The socket types are entirely different: AMD Socket FP7 for the Ryzen part and Intel BGA 2540 for the Arc part. The AMD chip uses a 4 nm TSMC process, while the Intel chip uses a 3 nm Intel process. Cache hierarchies differ substantially: AMD has 64 KB L1, 1 MB L2, and 16 MB L3 per the specified units, while Intel has 192 KB L1, 2.5 MB L2, and 18 MB L3.

Memory support differs by type and bandwidth. AMD supports DDR5 at 89.6 GB/s; Intel supports LPDDR5X at 136.5 GB/s. ECC is available on AMD but not on Intel. PCIe lanes are 20 Gen 4 lanes on AMD versus 4 Gen 5 lanes on Intel. Integrated graphics are Radeon 780M for AMD and Arc B370 for Intel.

The AMD chip has a release date of April 2024, while the Intel chip has a release date of May 2026. The AMD part has multiple part numbers (100-000001353 for FP7r2 and 100-000001381 for FP7), while the Intel part has a single part number (SA4QZ). Neither processor has a recorded launch MSRP, and both have locked multipliers.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Ryzen 7 PRO 8840HS and the Intel Arc G3. However, the AMD chip has 15 individual benchmark scores recorded, while the Intel chip has zero. This absence of Intel data means all recorded wins go to the AMD part, but the comparison must be interpreted carefully.

The AMD chip's Cinebench R23 multicore score is 14784, with a single-core score of 1724. The Cinebench R15 multicore score is 2458, and the single-core score is 271.5. These scores indicate strong multi-threaded rendering capability and solid single-thread performance.

The Passmark suite shows varied results. The multithread score is 26646, while the single-thread score is 3692. Integer math scores 93342, floating point math scores 55739, and extended instructions scores 22298. Data compression scores 311199, data encryption scores 18838, and random string sorting scores 37922. Find prime numbers scores 84, and physics scores 1351.

The AMD chip's average benchmark score is 39603, placing it in the 87th percentile of all CPUs in the database. Its nearest rivals include the AMD Ryzen AI 7 450 with an average score of 39485 (0.3% behind), the AMD Ryzen 7 9800X3D at 39768 (0.4% ahead), the AMD Ryzen 7 PRO 8845HS at 39325 (0.7% behind), and the AMD EPYC 4245P at 39215 (1% behind). These tight margins show the AMD chip sits in a competitive cluster.

Without Intel benchmark data, the only quantitative comparison possible is the specification table. The Intel chip's higher memory bandwidth and larger L3 cache suggest it could perform competitively in memory-bound tasks, but no measurement confirms this. The AMD chip's higher boost clock and mature Zen 4 architecture give it an advantage in latency-sensitive workloads.

The Verdict

The data presents an asymmetric comparison. The AMD Ryzen 7 PRO 8840HS has a complete benchmark profile with 15 recorded scores and an 87th percentile ranking. The Intel Arc G3 has no recorded benchmark scores and sits at the 50th percentile by default. This is not a measure of silicon quality but a reflection of data availability.

For users choosing between these two mobile processors, the AMD chip is the only one with confirmed performance measurements. Its Cinebench R23 multicore score of 14784 and single-core score of 1724 establish a baseline for productivity and general responsiveness. The 16 threads provide good parallelism for compilation, rendering, and content creation workloads.

The Intel Arc G3 offers structural advantages that cannot be verified with recorded data. Its 14 cores and 136.5 GB/s memory bandwidth could potentially outperform the AMD chip in specific multi-threaded scenarios, but the database contains no evidence of this. The 3 nm process node and 25 W TDP suggest a power-efficient design.

The practical recommendation follows the data. The AMD Ryzen 7 PRO 8840HS is the verified performer with strong scores across Cinebench and Passmark suites. It sits within 1% of several close rivals, including the Ryzen 7 9800X3D and the Ryzen 7 PRO 8845HS, making it a consistent mid-range mobile option.

The Intel Arc G3 is an unmeasured quantity. Its specifications indicate a capable design, but the lack of benchmarks means any performance claim would be speculative. Buyers needing confirmed performance should select the AMD chip. Buyers prioritizing the Intel platform's newer process node and higher memory bandwidth would need to accept uncertainty about actual scores. The database currently supports only one conclusion: the AMD chip delivers measurable performance, while the Intel chip remains an untested alternative.
