Architecture Differences

The two processors come from fundamentally different Intel design generations. The Arc G3 EXTREME uses the Panther Lake codename on a 3 nm process, while the i5-14450HX uses Raptor Lake-HX on a 10 nm process. Both are manufactured by Intel, but the process node difference is substantial and explains much of the performance and efficiency gap.

The core configurations differ significantly. The Arc G3 EXTREME has 14 cores and 14 threads, meaning no hyperthreading. The i5-14450HX has 10 cores and 16 threads, indicating a hybrid design with hyperthreading on some cores. Despite fewer physical cores, the i5-14450HX presents more threads to the operating system.

Clock speeds favor the i5-14450HX. Its base clock is 2.40 GHz versus 1.90 GHz for the Arc G3 EXTREME, and its boost clock is 4.80 GHz versus 4.70 GHz. The Arc G3 EXTREME compensates with a much lower TDP of 25 watts versus 55 watts for the i5-14450HX, a substantial efficiency advantage.

The Verdict

The recorded data supports a clear separation of use cases. The Intel Arc G3 EXTREME is the superior all-around processor for most workloads, with a higher average benchmark score (36699 vs 32040), a better percentile rank (85 vs 82), and wins in 13 of 17 head-to-head tests. Its 25 watt TDP, 3 nm process, and larger per-core caches make it the more efficient and broadly capable option.

The Intel Core i5-14450HX is the better choice for workloads that resemble Cinebench R23, particularly single-core performance. Its 34.4% lead in R23 singlecore and 27.1% lead in R23 multicore indicate a strong showing in rendering tasks that scale with its 16 threads. The 9.1% lead in PassMark integer math also suggests an advantage in integer-heavy applications.

The Arc G3 EXTREME is the pick for encryption, floating point math, physics simulation, data compression, and prime number computation. Its 53.3% lead in encryption and 70.5% lead in physics make it particularly strong for security-related and simulation workloads. The 153.1% lead in find prime numbers is the single largest margin in the entire comparison.

Users who prioritize efficiency, modern process technology, and the broadest set of workload wins should choose the Arc G3 EXTREME. Users who need maximum single-core performance in Cinebench-style tasks and value ECC memory support should choose the i5-14450HX. The data does not support a single winner across all scenarios; it supports two processors with complementary strengths.
