These adjacent scores indicate that Intel’s overall position is competitive with mid-range desktop parts, while AMD’s sits near flagship territory.

For users prioritizing integer throughput, compression, or multithreaded productivity, the data favors the Ryzen 7 8745HX. For users prioritizing floating point, physics simulation, or single-thread responsiveness, the Arc G3 EXTREME is the better fit.

Architecture Differences

The two processors come from different foundries and process nodes. AMD uses TSMC’s 5 nm process with a die size of 71 mm² and 6,570 million transistors. Intel uses its own 3 nm node, with no die size or transistor count recorded in the database.

AMD’s architecture is Zen 4 under the Dragon Range codename, part of the 8000 series. It has 8 cores and 16 threads, with a base clock of 3.60 GHz and a boost clock of 5.10 GHz. The thermal design power is 55 watts. The socket is AMD Socket FL1. The cache hierarchy is 64 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3.

Intel’s architecture is listed as Arc G3 under the Panther Lake codename. It has 14 cores and 14 threads, meaning no simultaneous multithreading. The base clock is 1.90 GHz and the boost clock is 4.70 GHz. The thermal design power is 25 watts, less than half of AMD’s. The socket is Intel BGA 2540. The cache hierarchy is larger per core: 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3.

Memory support differs. AMD uses DDR5 on a dual-channel bus with 83.2 GB/s bandwidth. Intel uses LPDDR5X on a dual-channel bus with 136.5 GB/s bandwidth, a 64% higher memory bandwidth figure. Neither processor supports ECC memory.

PCIe connectivity differs substantially. AMD offers Gen 5 with 28 lanes (CPU only). Intel offers Gen 5 with 4 lanes (CPU only). Integrated graphics also differ: AMD has the Radeon 610M, while Intel has the Arc B390.

The multiplier is unlocked on AMD, while Intel’s is locked. AMD’s production status is active with a release date of April 22, 2025. Intel’s production status is also active with a release date of May 27, 2026. Part numbers are 100-000001851 for AMD and SA4R3 for Intel.

The core count difference (14 versus 8) does not translate into multithread dominance for Intel, partly because Intel lacks SMT. AMD’s 16 threads versus Intel’s 14 threads, combined with higher boost clocks, explains the 2.8% AMD multithread win. Intel’s higher memory bandwidth may contribute to its floating point and physics advantages, though the recorded data does not directly link the two.

Where Each One Wins

The AMD Ryzen 7 8745HX wins in five benchmark categories. Integer math is its strongest territory, with a 41% lead over Intel. The multithread score goes AMD’s way by 2.8%, which is narrow but consistent with its 16 threads versus Intel’s 14. Data compression shows an 18.5% AMD advantage, making it suitable for file archiving, database workloads, and any task that spends time on string manipulation. Random string sorting goes AMD by 19.2%. Extended instructions favor AMD by 15.1%, covering workloads that use specialized CPU instruction sets.

The Intel Arc G3 EXTREME wins in six categories. Floating point math is its strongest territory, with a 28.7% lead. Physics simulation goes Intel by 33.2%, which is relevant for gaming physics and scientific simulation. Find prime numbers shows Intel ahead by 35.9%, a workload that stresses integer division and modular arithmetic. Data encryption favors Intel by 8.5%. Single-thread performance goes Intel by 9.6%, which improves responsiveness in lightly threaded applications.

The use-case split follows the benchmark patterns. The AMD Ryzen 7 8745HX suits workloads that are integer-bound: compression, sorting, parsing, and general productivity. The Intel Arc G3 EXTREME suits workloads that are floating-point-bound or latency-sensitive: simulation, physics, encryption, and single-threaded applications. The low 25 watt TDP of the Intel part also suggests a different thermal envelope, though the database does not record power draw under load. The 5.10 GHz boost clock on AMD and the 4.70 GHz boost on Intel both contribute to their respective single-thread results, with Intel’s higher single-thread score despite a lower boost clock indicating architectural efficiency differences.
