AMD Ryzen 7 8840HX vs Intel Arc G3 Comparison

Head-to-Head Benchmarks

The database contains detailed benchmark results for the AMD Ryzen 7 8840HX, while the Intel Arc G3 currently has no recorded benchmark scores. This creates an asymmetric comparison where only the AMD processor can be measured against the broader CPU landscape. The Ryzen 7 8840HX achieves an average benchmark score of 71,797 across all tested workloads, placing it in the 94th percentile of all CPUs in the database. This indicates that the AMD part outperforms approximately 94 percent of all recorded processors, a strong position for a mobile chip.

The Intel Arc G3, in contrast, has a recorded average benchmark score of zero and sits at the 50th percentile, which reflects the absence of any submitted test data rather than a true performance parity. The nearest rivals for the AMD Ryzen 7 8840HX provide useful reference points: the Intel Core Ultra 7 265KF scores 71,910, which is 0.2 percent higher than the AMD chip, making it essentially a statistical tie. The Intel Xeon Platinum 8270 scores 71,370, which is 0.6 percent lower, while both the Intel Xeon 6517P and Intel Xeon 6724P score 72,350 and 72,396 respectively, each about 0.8 percent ahead. These deltas are all within a single percentage point, meaning the Ryzen 7 8840HX competes directly with several high-end server and desktop parts despite being designed for mobile systems.

Looking at the actual workload results for the AMD Ryzen 7 8840HX, the Cinebench R23 multicore score of 25,265 demonstrates substantial thread scaling from its 12 cores and 24 threads. The single-core score of 1,857 in the same test shows a more modest result, which is typical for a mobile processor with a 55 watt TDP. In PassMark tests, the Ryzen 7 8840HX shows particular strength in integer math with a score of 146,506, floating point math at 86,747, and extended instructions at 36,527. Data compression reaches 496,427, while data encryption scores 29,919. The multithread score of 41,732 reflects the aggregate performance across all threads, while single-thread performance is recorded at 3,958 in both PassMark single-thread tests. Physics simulation scores 2,185, and finding prime numbers records 304. Random string sorting reaches 57,971.

The Intel Arc G3 cannot be compared directly on any of these metrics because the database contains no benchmark entries for it. The head-to-head benchmark array is empty, and neither processor has any recorded wins in direct comparison. This means any analysis of relative performance must rely on architectural specifications and the fact that the AMD part has demonstrated results while the Intel part does not yet have any measurable output in the database.

Where Each One Wins

From the recorded data, the AMD Ryzen 7 8840HX is the only processor with measurable wins, and it wins across every benchmark category that has been tested. The Cinebench R23 multicore score of 25,265 places it firmly in high-performance territory for mobile processors, while the PassMark multithread score of 41,732 confirms strong parallel workload handling. The integer math score of 146,506 and floating point math score of 86,747 indicate that the Zen 4 architecture excels in compute-heavy tasks such as scientific simulations, financial modeling, and video encoding. The extended instructions score of 36,527 suggests good support for modern instruction sets, which benefits encryption, compression, and multimedia workloads.

The data compression score of 496,427 is particularly high, indicating that the Ryzen 7 8840HX handles archiving, database compression, and file transfer workloads efficiently. Data encryption at 29,919 shows solid cryptographic throughput, which matters for VPNs, secure storage, and network services. The single-thread scores of 1,857 in Cinebench R23 and 3,958 in PassMark are respectable for a mobile chip, though not class-leading, which means single-threaded applications like legacy games or lightweight office tasks will perform adequately but not exceptionally.

For the Intel Arc G3, there are no benchmark wins to record because no test data exists. The processor has a 50th percentile ranking, which is the default value when no scores are present. This does not mean the Intel part is slower; it simply means the database has no evidence of its performance. The architectural specifications show that the Intel Arc G3 has 14 cores and 14 threads, which means no hyperthreading, while the AMD part has 12 cores and 24 threads. The Intel chip has a lower base clock of 1.90 GHz compared to 2.90 GHz on the AMD, and a lower boost clock of 4.60 GHz versus 5.10 GHz. The Intel part also has a much lower TDP of 25 watts compared to 55 watts on the AMD, which suggests the Intel chip is designed for power efficiency rather than raw performance.

The Intel Arc G3 features a larger L1 cache at 192 KB per core versus 64 KB per core on the AMD, and a larger L2 cache at 2.5 MB per core versus 1 MB per core. However, the AMD chip has a much larger L3 cache at 64 MB shared versus 18 MB shared on the Intel part. Memory bandwidth on the Intel chip is higher at 136.5 GB/s versus 83.2 GB/s on the AMD, and the Intel part uses LPDDR5X memory while the AMD uses DDR5. These differences suggest the Intel Arc G3 could have advantages in memory-intensive workloads and power-constrained environments, but without benchmark data, those advantages cannot be quantified.

The Verdict

The data clearly shows that the AMD Ryzen 7 8840HX is the only processor in this comparison with verified performance results. Its 94th percentile ranking and average benchmark score of 71,797 demonstrate that it is a high-performing mobile processor capable of competing with desktop and server chips that score within a single percentage point, such as the Intel Core Ultra 7 265KF at 0.2 percent higher, the Intel Xeon 6517P and 6724P at 0.8 percent higher, and the Intel Xeon Platinum 8270 at 0.6 percent lower. These rival deltas are negligible in real-world terms, meaning the Ryzen 7 8840HX delivers near-parity with several much larger and higher-power parts.

The Intel Arc G3 has no recorded benchmarks, so no verdict can be drawn from measured performance. Its specifications indicate a different design philosophy: 14 cores without hyperthreading, a lower 25 watt TDP, a smaller L3 cache at 18 MB, and a higher memory bandwidth at 136.5 GB/s. These features point toward a processor optimized for efficiency and memory throughput rather than maximum compute throughput. However, the absence of benchmark data means that any performance claim for the Intel part is unsupported by the database.

For users who rely on measured results, the AMD Ryzen 7 8840HX is the only choice that can be justified from the data. It delivers strong multicore performance, high integer and floating point throughput, and competitive single-thread scores. The Intel Arc G3 remains an unquantified option, and its actual performance cannot be assessed until benchmark submissions appear in the database. From the recorded information, the AMD processor is the only one with evidence of capability, and it sits at a high performance level relative to all CPUs tracked.

Architecture Differences

The AMD Ryzen 7 8840HX is built on the Zen 4 architecture with the Dragon Range codename, using a 5 nm process from TSMC with 13,140 million transistors across a die size of 2x 71 mm². It operates on AMD Socket FL1 and features 12 cores with 24 threads, a base clock of 2.90 GHz, a boost clock of 5.10 GHz, and a 55 watt TDP. The multiplier is unlocked, allowing manual overclocking. The processor supports DDR5 memory in a dual-channel configuration with 83.2 GB/s bandwidth, and it provides PCIe Gen 5 with 28 lanes for the CPU. The integrated graphics are Radeon 610M. The cache hierarchy includes 64 KB L1 per core, 1 MB L2 per core, and 64 MB shared L3. The release date is recorded as 2025-04-22.

The Intel Arc G3 uses the Panther Lake codename with a 3 nm process from Intel, and it has 14 cores with 14 threads, meaning no hyperthreading. The base clock is 1.90 GHz and the boost clock is 4.60 GHz, with a TDP of 25 watts, which is less than half the AMD chip's power envelope. It uses Intel BGA 2540 socket and supports LPDDR5X memory in a dual-channel configuration with 136.5 GB/s bandwidth, which is significantly higher than the AMD part. The PCIe interface is Gen 5 with only 4 lanes, which is much more limited than the AMD's 28 lanes. The integrated graphics are Arc B370. The cache layout differs notably: 192 KB L1 per core and 2.5 MB L2 per core are larger than the AMD's per-core caches, but the shared L3 is only 18 MB versus 64 MB on the AMD. The multiplier is locked, so no manual overclocking is possible. The release date is recorded as 2026-05-27.

Both processors are mobile parts with active production status, and neither supports ECC memory. The AMD part has a higher transistor count and larger die, while the Intel part uses a smaller process node. The architectural differences suggest that the AMD Ryzen 7 8840HX prioritizes raw compute throughput with its high core count, large L3 cache, and high boost clock, while the Intel Arc G3 emphasizes power efficiency with its 25 watt TDP, higher memory bandwidth, and larger per-core caches. The lack of benchmark data for the Intel part means that these architectural distinctions cannot be translated into measured performance differences, but they do indicate divergent design targets for the two processors.
