AMD Ryzen 9 8940HX vs Intel Arc G3 Comparison

The AMD Ryzen 9 8940HX and the Intel Arc G3 occupy completely different positions in the mobile processor landscape, as the recorded data shows. The Ryzen 9 8940HX is a high-core-count part built for sustained multi-threaded workloads, while the Arc G3 is a lower-power, efficiency-focused design. The database places the Ryzen 9 8940HX in the 95th percentile among all CPUs, indicating it outperforms the vast majority of recorded processors. The Arc G3 sits in the 50th percentile, but it has no recorded benchmark scores in the database, so its comparative position currently rests on specifications alone. The Ryzen 9 8940HX carries an average benchmark score of 81103, while the Arc G3 shows an average score of 0 due to missing data. The closest competing processors to the Ryzen 9 8940HX, based on average score, are the Intel Xeon w5-3535X at 81115 and the Intel Core i9-14900KS at 81127, both essentially tied with a negligible difference. The AMD Ryzen AI Max+ PRO 395 trails by 0.4 percent, and the Intel Xeon 638 trails by 0.5 percent. These figures place the Ryzen 9 8940HX in a tight cluster with some of the strongest desktop and workstation chips in the database.

The Verdict

The data indicates that the AMD Ryzen 9 8940HX is the choice for users who require maximum multi-threaded compute in a mobile package. Its 16 cores and 32 threads, combined with a boost clock of 5.30, produce benchmark results that place it in the 95th percentile of all CPUs. The Arc G3, by contrast, offers no recorded benchmark scores, so its performance cannot be verified against the same metrics. The Arc G3 does present a significantly lower thermal design point, with a TDP of 25 compared to the Ryzen 9 8940HX's 55, which suggests it is designed for efficiency rather than peak throughput. The Arc G3 also uses a newer process node at 3 nm from Intel, while the Ryzen 9 8940HX uses a 5 nm node from TSMC. For workloads that depend on raw core count and thread parallelism, the Ryzen 9 8940HX is the clear selection based on the available data. The Arc G3, with 14 cores and 14 threads, lacks simultaneous multithreading, so it will process fewer concurrent threads. The Ryzen 9 8940HX also supports PCIe Gen 5 with 28 lanes, while the Arc G3 supports PCIe Gen 5 with only 4 lanes, which matters for external GPU or storage expansion. The Arc G3 has no launch MSRP recorded and the Ryzen 9 8940HX also has no launch MSRP recorded, so neither can be compared on that basis. The Ryzen 9 8940HX has an unlocked multiplier, allowing overclocking, whereas the Arc G3 has a locked multiplier. The verdict from the database is straightforward: the Ryzen 9 8940HX is built for performance, and the Arc G3 is built for efficiency, with no overlap in their intended roles.

Architecture Differences

The architectural split between these two processors is substantial. The AMD Ryzen 9 8940HX uses the Zen 4 architecture under the Dragon Range codename, and it belongs to the 8000 series. It is manufactured on a 5 nm process at TSMC, with a transistor count of 13,140 million spread across a die size of 2x 71 mm². The Intel Arc G3 uses the Panther Lake codename and is manufactured on a 3 nm process at Intel's own foundry. The Arc G3 does not have a listed architecture name, nor does it have recorded transistor or die size data. The Ryzen 9 8940HX features 16 cores and 32 threads, enabled by simultaneous multithreading, while the Arc G3 features 14 cores and 14 threads, indicating no multithreading capability. The cache hierarchies differ significantly. The Ryzen 9 8940HX has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 64 MB of L3 cache. The Arc G3 has 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 18 MB of shared L3 cache. The larger per-core cache on the Arc G3 may benefit single-threaded latency, but the Ryzen 9 8940HX has far more total L3 capacity. Memory support also differs: the Ryzen 9 8940HX uses DDR5 on a dual-channel bus with a memory bandwidth of 83.2 GB/s, while the Arc G3 uses LPDDR5X on a dual-channel bus with a memory bandwidth of 136.5 GB/s. The Arc G3 offers higher bandwidth, which is typical for integrated designs that share memory with graphics. The integrated graphics differ as well: the Ryzen 9 8940HX includes a Radeon 610M, while the Arc G3 includes an Arc B370. The Arc G3's integrated graphics is a newer Arc-branded part, which may deliver different graphics capabilities, though no benchmark data is available to quantify this. The Ryzen 9 8940HX supports PCIe Gen 5 with 28 lanes from the CPU, while the Arc G3 supports PCIe Gen 5 with only 4 lanes. Neither processor supports ECC memory. The production status for both is listed as active, with the Ryzen 9 8940HX released on 2025-04-22 and the Arc G3 released on 2026-05-27. The Ryzen 9 8940HX uses the AMD Socket FL1, while the Arc G3 uses Intel BGA 2540, so they are not interchangeable in any system.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the AMD Ryzen 9 8940HX and the Intel Arc G3, and the Arc G3 has no individual benchmark scores recorded. Therefore, the comparison must rely on the Ryzen 9 8940HX's recorded performance and the Arc G3's specifications. The Ryzen 9 8940HX delivers a Cinebench R23 multi-core score of 32521 and a single-core score of 1917. In Cinebench R15, it scores 5355 multi-core and 292 single-core. These figures show a processor that excels in both heavily threaded and lightly threaded workloads. The PassMark suite further confirms this. The Ryzen 9 8940HX scores 49731 in multi-thread, 3874 in single-thread, 189221 in integer math, and 113921 in floating point math. It also produces 650984 in data compression, 39318 in data encryption, 47802 in extended instructions, 75381 in random string sorting, 2104 in physics, and 251 in prime number finding. The average benchmark score of 81103 places it among the top tier of all CPUs in the database, at the 95th percentile. Its nearest rivals are the Intel Xeon w5-3535X at 81115, the Intel Core i9-14900KS at 81127, the AMD Ryzen AI Max+ PRO 395 at 80762, and the Intel Xeon 638 at 80723. The Ryzen 9 8940HX is effectively tied with the Xeon w5-3535X and the Core i9-14900KS, and it leads the Ryzen AI Max+ PRO 395 and the Xeon 638 by less than a full percentage point. The Arc G3 has no comparable data, so its wins cannot be quantified. Based on specifications alone, the Arc G3 holds advantages in process node (3 nm versus 5 nm), memory bandwidth (136.5 GB/s versus 83.2 GB/s), L1 cache per core (192 KB versus 64 KB), and L2 cache per core (2.5 MB versus 1 MB). It also has a lower TDP of 25 versus 55. These specification advantages do not translate into recorded benchmark results, as the Arc G3 has no entries in the database. The Ryzen 9 8940HX, on the other hand, has a complete set of benchmark data that demonstrates strong multi-core and single-core performance. The data shows that the Ryzen 9 8940HX is the only one of the two with verifiable performance, and that performance is elite. The Arc G3 remains an unmeasured quantity in the database, with its 50th percentile ranking derived from an average score of 0, which indicates a lack of recorded data rather than a measured performance level.
