Intel Arc G3 EXTREME vs Intel Core i7-14700HX Comparison

The Verdict

The benchmark data splits these two mobile processors into clearly different roles. The Intel Core i7-14700HX wins 13 of 17 head-to-head tests and holds an average benchmark score of 45953, which places it in the 89th percentile of all CPUs. The Intel Arc G3 EXTREME wins only 4 tests, with an average score of 36699 and an 85th percentile ranking. For users who need maximum multi-threaded throughput, the i7-14700HX is the stronger choice across nearly every measured workload, leading by 40.4% in Cinebench R23 multi-core and by 45.8% in PassMark integer math. The Arc G3 EXTREME does show advantages in specific single-threaded and physics-related tasks, but those wins do not offset the i7-14700HX's broad dominance. The data indicates the i7-14700HX suits heavy productivity, content creation, and compilation workloads, while the Arc G3 EXTREME fits scenarios where single-thread responsiveness and lower power draw matter more.

Architecture Differences

The two processors come from different Intel design families and process nodes. The Arc G3 EXTREME uses the Panther Lake architecture built on a 3 nm process, while the i7-14700HX uses Raptor Lake-HX on a 10 nm node.

Memory and platform support also separates them. The i7-14700HX supports both DDR4 and DDR5 memory with ECC enabled, while the Arc G3 EXTREME uses LPDDR5X without ECC. The Arc G3 EXTREME records a memory bandwidth of 136.5 GB/s, but the i7-14700HX's bandwidth is not listed. PCIe connectivity favors the i7-14700HX with 16 Gen 5 lanes, while the Arc G3 EXTREME has only 4 Gen 5 lanes. The i7-14700HX uses Intel BGA 1964, the Arc G3 EXTREME uses Intel BGA 2540. Integrated graphics differ: the Arc G3 EXTREME pairs with Arc B390, the i7-14700HX with UHD Graphics 770. The i7-14700HX has an unlocked multiplier; the Arc G3 EXTREME does not.

Head-to-Head Benchmarks

Single-core Cinebench results also favor the i7-14700HX, though by smaller margins: 296 versus 267 in R15 (9.8%), 1843 versus 1545 in R20 (16.2%), and 2103 versus 1862 in R23 (11.5%).

PassMark integer math delivers the widest separation. The i7-14700HX scores 131296 against 71164, a 45.8% advantage. Data compression shows a 30% lead for the i7-14700HX (438539 versus 307094). Random string sorting favors the i7-14700HX by 23.1% (48544 versus 37331). PassMark multi-thread scores put the i7-14700HX at 36566 versus 30659, a 16.2% lead. Floating-point math shows a smaller 7.4% edge (93836 versus 86929). Data encryption and extended instructions both go to the i7-14700HX with 8.5% and 6.6% leads respectively.

The Arc G3 EXTREME claims three unique wins. PassMark find prime numbers shows a 50.3% advantage (248 versus 165). PassMark physics scores 2515 versus 2252, an 11.7% lead. PassMark single-thread (and the duplicate singlethread entry) records 4293 versus 3947, an 8.8% win. These results indicate the Arc G3 EXTREME has strengths in integer prime computation, physics simulation, and raw single-thread performance, but those wins cover a narrow portion of the tested workload set.

Where Each One Wins

The i7-14700HX is the clear choice for multi-threaded productivity. Cinebench R23 multi-core at 24595 and R15 multi-core at 3812 show it handles heavily parallel workloads with a 40% or greater margin over the Arc G3 EXTREME. PassMark integer math at 131296 versus 71164 points to strong general arithmetic performance, and data compression at 438539 indicates faster archival and file-handling tasks. The 28 threads versus 14 threads, combined with 33 MB of shared L3 cache versus 18 MB, supports this split. The i7-14700HX also wins every single-core Cinebench test, though by smaller margins, and its 5.50 GHz boost clock provides a higher ceiling for bursty workloads.

The Arc G3 EXTREME wins in three specific areas. PassMark find prime numbers at 248 versus 165 shows a 50.3% advantage in prime-number computation, a workload that benefits from its architecture. PassMark physics at 2515 versus 2252 gives an 11.7% lead for simulation-style tasks. PassMark single-thread at 4293 versus 3947 shows 8.8% better single-thread performance than the i7-14700HX, which is notable given the i7-14700HX's higher boost clock. The Arc G3 EXTREME also operates at a 25 W TDP compared to 55 W, which indicates lower power draw for thermally constrained mobile designs.

For users deciding between them, the data favors the i7-14700HX for rendering, compilation, data processing, and any task that scales with core count. The Arc G3 EXTREME suits workloads that rely on single-thread speed, physics calculations, or prime-number sieving, and its lower TDP makes it better suited for thinner, cooler-running systems. The i7-14700HX's 13 wins versus 4 wins, its 89th percentile ranking, and its 45953 average score confirm it as the higher-performing part in the majority of measured scenarios.
