AMD Ryzen 9 8940HX vs Intel Arc G3 EXTREME Comparison

The AMD Ryzen 9 8940HX and Intel Arc G3 EXTREME are both mobile processors aimed at different performance tiers. The recorded data shows a decisive overall victory for the AMD part in raw compute, but the Intel chip claims specific wins in single-threaded and physics-based workloads. The following analysis breaks down the benchmark results from the database.

Head-to-Head Benchmarks

The benchmark suite in the database shows the AMD Ryzen 9 8940HX dominating the Intel Arc G3 EXTREME in 12 of the 15 recorded tests. The largest margin appears in PassMark integer math, where the AMD chip scores 189221 against 71164, a 165.9% difference. This result indicates a massive advantage in general arithmetic and logic operations, which is expected given the core count and thread count disparity.

Cinebench results reinforce this multi-core supremacy. In Cinebench R23 multi-core, the AMD Ryzen 9 8940HX scores 32521, while the Intel Arc G3 EXTREME scores 14655, a 121.9% lead. The Cinebench R15 multi-core test shows an even starker relative gap: 5355 versus 2192, a 144.3% difference. These scores confirm that the AMD processor delivers more than double the multi-threaded rendering performance in legacy and modern Cinebench versions.

The data compression test follows the same pattern. The AMD Ryzen 9 8940HX scores 650984, compared to 307094 for the Intel Arc G3 EXTREME, a 112% advantage. Similarly, random string sorting shows 75381 versus 37331, a 101.9% lead for AMD. Encryption performance shows 39318 against 23881, a 64.6% gap, and extended instruction results show 47802 versus 24017, a 99% difference.

Floating-point math also favors AMD, with a score of 113921 versus 86929 for Intel, a 31.1% lead. The PassMark multi-thread test shows 49731 for AMD against 30659 for Intel, a 62.2% advantage. Even the closest multi-core-style result, PassMark find prime numbers, goes to AMD with 251 versus 248, a slim 1.2% margin.

The Intel Arc G3 EXTREME does secure three wins. The most significant is in PassMark single-thread, where Intel scores 4293 against AMD's 3874, a 9.8% lead. The same score appears in the duplicate PassMark singlethread field. The other Intel win is in PassMark physics, where it scores 2515 versus 2104 for AMD, a 16.3% margin. These wins show that the Intel part has a measurable edge in lightly threaded and physics-simulation workloads, but they do not offset the scale of AMD's multi-threaded dominance.

The Verdict

The database places the AMD Ryzen 9 8940HX in the 95th percentile of all CPUs, with an average benchmark score of 81103. Its nearest rivals include 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 deltas are small, ranging from 0 to 0.5%, which indicates the AMD chip sits at the top tier of desktop and mobile compute performance.

The Intel Arc G3 EXTREME sits in the 85th percentile with an average benchmark score of 36699. Its nearest rivals are the Intel Core Ultra 5 225 at 36938, the AMD Ryzen 5 5600F at 36945, the AMD Ryzen 5 5500X3D at 37018, and the AMD Ryzen AI 7 PRO 450 at 37093. The deltas are negative, ranging from -0.6% to -1.1%, meaning the Intel chip slightly trails these mid-range parts in average score.

The data indicates that the AMD Ryzen 9 8940HX is the appropriate choice for applications that scale with cores and threads. Its 16 cores, 32 threads, and 64 MB of L3 cache support workloads such as video rendering, code compilation, and data processing. The Intel Arc G3 EXTREME, with 14 cores and 14 threads, fits scenarios where single-thread responsiveness and physics calculations take priority, but its overall compute throughput is substantially lower.

Specification Differences

The two processors differ across nearly every core specification. The AMD Ryzen 9 8940HX uses 16 cores and 32 threads, while the Intel Arc G3 EXTREME uses 14 cores and 14 threads. Base clocks are 2.40 GHz for AMD and 1.90 GHz for Intel; boost clocks are 5.30 GHz and 4.70 GHz respectively. The AMD part has a TDP of 55 watts, while the Intel part has a TDP of 25 watts.

Socket types differ completely. The AMD Ryzen 9 8940HX uses AMD Socket FL1, and the Intel Arc G3 EXTREME uses Intel BGA 2540. The AMD processor supports DDR5 memory, while the Intel processor supports LPDDR5X. Both use a dual-channel memory bus, but memory bandwidth differs: the AMD chip has 83.2 GB/s, and the Intel chip has 136.5 GB/s.

PCIe support also differs. The AMD Ryzen 9 8940HX provides Gen 5 with 28 lanes, while the Intel Arc G3 EXTREME provides Gen 5 with 4 lanes. Integrated graphics differ as well: the AMD part includes Radeon 610M, and the Intel part includes Arc B390. The AMD multiplier is unlocked, while the Intel multiplier is not. Part numbers are 100-000001849 for AMD and SA4R3 for Intel.

Architecture Differences

The AMD Ryzen 9 8940HX uses the Zen 4 architecture on the Dragon Range codename, built on a 5 nm process at TSMC. The transistor count is 13,140 million, and the die size is 2x 71 mm². The Intel Arc G3 EXTREME uses the Panther Lake codename on a 3 nm process at Intel, with no transistor count or die size recorded in the database.

Cache layouts differ substantially. The AMD chip has 64 KB of L1 per core, 1 MB of L2 per core, and 64 MB of L3 cache. The Intel chip has 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3 cache. Neither CPU supports ECC memory, and neither has 3D V-Cache.

The Intel part uses a newer process node at 3 nm compared to AMD's 5 nm, which partially explains its lower TDP of 25 watts. The AMD part compensates with a much larger L3 cache (64 MB versus 18 MB) and double the threads. The Intel part has no listed architecture field, while the AMD part specifies Zen 4.

Where Each One Wins

The AMD Ryzen 9 8940HX wins in multi-threaded rendering, as shown by Cinebench R15 and R23 multi-core scores with leads of 144.3% and 121.9%. It also wins in data compression (112% lead), random string sorting (101.9%), extended instructions (99%), and encryption (64.6%). Integer math is its largest win at 165.9%, and floating-point math shows a 31.1% advantage. The PassMark multi-thread score shows a 62.2% lead. This processor is suited for heavily parallel tasks such as content creation, scientific computing, and server-style workloads.

The Intel Arc G3 EXTREME wins in PassMark single-thread by 9.8%, which indicates a slight advantage in applications that depend on one core's responsiveness. It also wins PassMark physics by 16.3%, which suggests a benefit in physics simulation and certain game engine calculations. The Intel part also has higher memory bandwidth at 136.5 GB/s versus 83.2 GB/s, which could benefit memory-bound tasks despite its lower overall compute scores.

The data shows a clear split: the AMD Ryzen 9 8940HX is the dominant multi-threaded processor, while the Intel Arc G3 EXTREME offers specific single-thread and physics advantages at a much lower TDP of 25 watts versus 55 watts. The average benchmark scores, 81103 versus 36699, place them in different performance classes entirely.
