Architecture Differences

The two processors come from different Intel design families and are built on different process nodes. The Intel Arc G3 EXTREME uses the Panther Lake architecture on a 3 nm process from Intel's own foundry. The Core i7-14650HX is based on the Raptor Lake architecture, specifically the Raptor Lake-HX refresh, and uses a 10 nm process. The die size for the i7-14650HX is 257 mm², while the database does not list a die size for the Arc G3 EXTREME.

Core and thread counts differ substantially. The Arc G3 EXTREME has 14 cores and 14 threads, indicating no hyperthreading support. The Core i7-14650HX has 16 cores and 24 threads, meaning 8 of its cores support hyperthreading. This thread advantage is a major factor in the i7's multi-core benchmark results.

Cache hierarchies are organized differently. The Arc G3 EXTREME has 192 KB of L1 cache per core and 2.5 MB of L2 cache per core, with 18 MB of shared L3. The Core i7-14650HX uses 80 KB of L1 per core and 2 MB of L2 per core, but has a larger 30 MB shared L3 cache. The total L3 capacity favors the i7 by 12 MB.

Memory support also differs. The Arc G3 EXTREME supports LPDDR5X memory on a dual-channel bus with a rated bandwidth of 136.5 GB/s. The Core i7-14650HX supports both DDR4 and DDR5 memory on a dual-channel bus, but the database does not record a memory bandwidth figure for it. ECC memory is supported on the i7 but not on the Arc G3 EXTREME.

PCIe connectivity is another differentiator. The Arc G3 EXTREME provides Gen 5 with 4 lanes (CPU only), while the Core i7-14650HX provides Gen 5 with 16 lanes (CPU only). This gives the i7 more expansion bandwidth for discrete components.

The integrated graphics are different as well. The Arc G3 EXTREME includes Arc B390 graphics, while the Core i7-14650HX includes UHD Graphics 710. The Arc G3 EXTREME uses the Intel BGA 2540 socket, while the i7 uses Intel BGA 1964. The i7 has an unlocked multiplier, while the Arc G3 EXTREME does not.

Both are mobile market segment parts and are currently listed as Active in production. The Arc G3 EXTREME has a release date of 2026-05-27, while the Core i7-14650HX has a release date of 2024-01-07. The TDP ratings are 25 W for the Arc G3 EXTREME and 55 W for the Core i7-14650HX.

The Verdict

The recorded data points to a clear overall winner in the Core i7-14650HX. It holds an 11.8% higher average benchmark score (41576 vs 36699) and a higher percentile ranking (88th vs 85th). It wins the majority of the head-to-head tests, including all six Cinebench benchmarks and the most demanding PassMark multi-threaded workloads.

The i7's 16 cores and 24 threads, combined with its 5.20 GHz boost clock, give it a substantial edge in rendering and integer-heavy work. The 30 MB L3 cache and 16 PCIe Gen 5 lanes also make it the more capable platform for sustained professional workloads and expansion.

The Arc G3 EXTREME is not without merit. Its single-thread PassMark score is 11.8% higher than the i7's, and it wins specialized workloads like prime number finding (63.2% ahead) and physics calculations (14.2% ahead). The 3 nm Panther Lake architecture and 25 W TDP indicate a far more power-efficient design. Its Arc B390 integrated graphics are also a notable upgrade over the UHD Graphics 710 in the i7.

For users who need maximum multi-core throughput, Cinebench results, and data compression performance, the Core i7-14650HX is the stronger choice. For workloads that favor single-thread PassMark performance, floating point math, or encryption, the Arc G3 EXTREME delivers competitive results at a fraction of the TDP.
