Architecture Differences

The Intel Arc G3 and Intel Core i7-14700HX represent two distinct architectural approaches from Intel. The Arc G3, codenamed Panther Lake, is a 14-core, 14-thread processor built on a 3 nm process node. Its lack of thread duplication (14 threads for 14 cores) indicates a straightforward design where every core handles exactly one thread. The processor uses an Intel BGA 2540 socket and belongs to the Arc G3 generation. The L1 cache is 192 KB per core, and the L2 cache is 2.5 MB per core, with 18 MB of shared L3 cache. The integrated graphics are labeled Arc B370. Memory support is limited to LPDDR5X, running on a dual-channel bus with a measured bandwidth of 136.5 GB/s. The PCIe interface is Gen 5 with 4 lanes, CPU only.

The Intel Core i7-14700HX, in contrast, is part of the Core 14th Gen series, codenamed Raptor Lake-HX Refresh, and uses the Raptor Lake architecture. It is a 20-core, 28-thread processor built on a 10 nm process node, with a die size of 257 mm². The socket is Intel BGA 1964. Cache sizes are smaller per core: 80 KB L1 per core and 2 MB L2 per core, but the shared L3 cache is larger at 33 MB. The i7-14700HX supports both DDR4 and DDR5 memory on a dual-channel bus, though no memory bandwidth figure is recorded. ECC memory is supported, and the PCIe interface is Gen 5 with 16 lanes, CPU only. The integrated graphics are UHD Graphics 770. This processor has an unlocked multiplier, while the Arc G3 does not.

The process node difference is stark: 3 nm versus 10 nm. This suggests the Arc G3 uses a newer manufacturing technology that could improve power efficiency per transistor, but the database records no power draw figures for either chip beyond their TDP ratings. The Arc G3 has a TDP of 25, while the i7-14700HX has a TDP of 55. The architecture also differs in memory controller support: the Arc G3 is limited to LPDDR5X, likely targeting low-power mobile designs, whereas the i7-14700HX supports both DDR4 and DDR5, offering broader compatibility with existing memory modules.

The core organization is fundamentally different. The i7-14700HX with 28 threads from 20 cores implies a hybrid layout (performance and efficiency cores), whereas the Arc G3's 14 threads from 14 cores suggests a homogeneous core arrangement. The per-core cache differences are notable: the Arc G3 has more L1 and L2 per core, but the i7-14700HX has nearly double the L3 capacity, which may benefit workloads with large shared working sets.

Head-to-Head Benchmarks

The database contains benchmark scores for the Intel Core i7-14700HX but no recorded benchmark scores for the Intel Arc G3. The head-to-head comparison table is empty, and the wins counters show 0 for both processors. This means the quantitative comparison relies entirely on the i7-14700HX's measured results and the architectural specifications of the Arc G3.

For the Intel Core i7-14700HX, the Cinebench R23 multi-core score is 24595, and the single-core score is 2103. The Cinebench R20 multi-core score is 13059, with single-core at 1843. The Cinebench R15 multi-core score is 3812, and single-core is 296. Geekbench shows a multi-core score of 14390 and a single-core score of 2116.

Passmark results for the i7-14700HX include: multithread score of 36566, single-thread score of 3947 (recorded twice under slightly different test names), integer math at 131296, floating point math at 93836, extended instructions at 25718, data encryption at 26092, data compression at 438539, find prime numbers at 165, random string sorting at 48544, and physics at 2252.

The average benchmark score for the i7-14700HX is 45953, placing it at the 89th percentile among all CPUs in the database. Its nearest rivals include the AMD EPYC 7303 with an average score of 45960 and a delta of 0%, the AMD EPYC 4364P at 45970 with 0% delta, the AMD Ryzen AI 9 HX 375 at 46030 with -0.2% delta, and the Intel Core Ultra 5 235 at 46062 with -0.2% delta. This means the i7-14700HX is effectively tied with these server and mobile processors in aggregate performance, sitting within 0.2% of the two closest competitors.

Since the Arc G3 has no benchmark scores, the data cannot confirm any performance advantage for it. The percentile ranking for the Arc G3 is 50, which is lower than the i7-14700HX's 89th percentile. The avgBenchmarkScore for the Arc G3 is 0, indicating no measured results are available.

The gap in multi-core performance is likely substantial given the core and thread differences, but without Arc G3 scores, the analysis must remain qualitative. The i7-14700HX delivers 28 threads versus 14 threads, and its 33 MB L3 cache versus 18 MB suggests a strong multi-threaded advantage. The boost clock advantage of 5.50 GHz versus 4.60 GHz also points to higher single-threaded performance, though the newer 3 nm process on the Arc G3 could offset some of that through improved instructions per clock.

The Verdict

The recorded data shows a clear imbalance: the Intel Core i7-14700HX has extensive benchmark results, while the Intel Arc G3 has none. The i7-14700HX sits at the 89th percentile among all CPUs, with an average benchmark score of 45953. The Arc G3 sits at the 50th percentile with an average score of 0, which reflects the absence of measurements rather than actual performance.

For workloads that depend on multi-threaded throughput, the i7-14700HX is the only processor with data confirming capability. Its 28 threads, 5.50 GHz boost clock, and 33 MB L3 cache align with high multi-core scores such as 24595 in Cinebench R23 multi-core and 36566 in Passmark multithread. The 20 cores provide a substantial physical core count.

For workloads that prioritize power efficiency, the Arc G3 has a lower TDP of 25 versus 55, and a more advanced 3 nm process node. The 4.60 GHz boost clock is lower but still capable. The LPDDR5X memory support with 136.5 GB/s bandwidth could benefit memory-sensitive tasks.

The i7-14700HX also offers more PCIe lanes (16 versus 4) and ECC memory support, making it more suitable for workstation-class mobile tasks. The unlocked multiplier allows overclocking, which the Arc G3 does not permit.

The data does not support a recommendation for the Arc G3 in performance-critical scenarios, because no benchmark scores exist. The i7-14700HX is the only processor with verified performance metrics.

Where Each One Wins

The Intel Core i7-14700HX wins in every measured benchmark category, based on the available data. Its Cinebench scores (R15, R20, R23) all show strong multi-core and single-core results. Geekbench multi-core at 14390 and single-core at 2116 confirm balanced performance. Passmark scores across integer math, floating point math, data compression, encryption, extended instructions, random string sorting, physics, and single-thread tests all demonstrate capability.

The i7-14700HX's nearest rivals are all within 0.2% of its average score, indicating it performs at parity with server-class AMD EPYC parts and newer Intel Core Ultra processors. This places it in a competitive tier for mobile computing.

The Intel Arc G3 has no recorded wins because no benchmark data exists. Its advantages are purely architectural: lower TDP of 25, smaller process node of 3 nm, higher per-core L1 and L2 cache, and a dedicated memory bandwidth figure of 136.5 GB/s. These specifications suggest it could win in power-constrained environments, but the database does not confirm this with scores.

For use cases involving heavy parallel processing, video rendering, software compilation, or data analysis, the i7-14700HX is the only processor with demonstrated performance. For use cases involving battery life or thermal limits, the Arc G3's lower TDP and advanced process node may offer efficiency benefits, but the lack of measurements prevents a quantified conclusion. The i7-14700HX also wins in expandability with 16 PCIe lanes and ECC support, while the Arc G3's 4 lanes and lack of ECC limit its workstation potential.
