AMD Ryzen 7 8840HX vs Intel Arc G3 EXTREME Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive overall victory for the AMD Ryzen 7 8840HX, which wins 8 of the 13 head-to-head comparisons. The most lopsided result appears in PassMark integer math, where AMD delivers 146506 against Intel's 71164, a 105.9% advantage that nearly doubles the output. This single test captures the fundamental throughput gap between the two processors. Similarly, in Cinebench R23 multi-core, the AMD scores 25265 versus 14655 for the Intel, a 72.4% lead that reflects the AMD's superior thread scaling.

The AMD also wins decisively in data compression, scoring 496427 against 307094, a 61.7% gap. Extended instructions favor AMD at 36527 versus 24017, a 52.1% difference. Random string sorting shows AMD ahead at 57971 versus 37331, a 55.3% margin. The multi-threaded PassMark test confirms the pattern with AMD at 41732 and Intel at 30659, a 36.1% lead. Data encryption shows AMD at 29919 versus 23881, a 25.3% advantage. Even the prime number test, often sensitive to single-thread efficiency, goes to AMD with 304 versus 248, a 22.6% margin.

The Intel Arc G3 EXTREME claims 5 wins, but all are narrow except for one. The largest Intel victory comes in PassMark physics, where it scores 2515 against AMD's 2185, a 13.1% advantage. This suggests the Intel's core configuration handles the physics workload more efficiently. In single-thread tests, the Intel edges ahead with 4293 versus 3958 in PassMark single-thread, a 7.8% lead, and 1862 versus 1857 in Cinebench R23 single-core, a marginal 0.3% difference. Floating-point math shows Intel at 86929 versus 86747, a 0.2% lead that is statistically negligible. These wins are concentrated in workloads that scale with single-core efficiency or specialized instruction paths, not in raw throughput.

Where Each One Wins

The AMD Ryzen 7 8840HX dominates every multi-threaded, data-heavy, and integer-intensive workload. The 105.9% advantage in integer math indicates that any application relying on integer operations, such as databases, financial modeling, or general logic processing, will see dramatic performance gains. The 72.4% lead in Cinebench R23 multi-core translates directly to rendering, video encoding, and compilation tasks. The 61.7% compression win benefits archive management, file transfer, and backup workloads. The 52.1% extended instructions margin covers SIMD-heavy code, including multimedia processing and scientific simulations. The 55.3% random string sorting advantage applies to text processing, sorting algorithms, and data analytics pipelines.

The Intel Arc G3 EXTREME claims the physics simulation workload with a 13.1% lead, which suggests an advantage in certain game physics or engineering simulation scenarios. The single-thread wins, while narrow at 0.3% in Cinebench and 7.8% in PassMark, indicate that the Intel holds a slight edge in lightly threaded applications like legacy software, some office tasks, or interactive user interfaces. The floating-point math tie, with Intel at 0.2% ahead, means both processors are comparable for scientific floating-point calculations, though the margin is too small to constitute a practical advantage.

For mixed workloads, the AMD's 36.1% multi-thread lead and 25.3% encryption advantage make it the stronger choice for server-like tasks, virtualization, and security-heavy operations. The Intel's wins are confined to specific niches: physics, single-thread responsiveness, and floating-point parity. No benchmark shows the Intel ahead in any data-heavy or integer-heavy category.

Architecture Differences

The AMD Ryzen 7 8840HX uses the Zen 4 architecture on a 5 nm process from TSMC, with the Dragon Range codename. It packs 12 cores and 24 threads, enabling simultaneous multi-threading. The cache hierarchy consists of 64 KB L1 per core, 1 MB L2 per core, and 64 MB shared L3. The Intel Arc G3 EXTREME uses the Panther Lake codename on a 3 nm process from Intel's own foundry. It has 14 cores and 14 threads, meaning no simultaneous multi-threading. Its cache layout is 192 KB L1 per core, 2.5 MB L2 per core, and 18 MB shared L3.

The process node difference is significant: 5 nm versus 3 nm. The Intel uses a denser, more advanced node, which partly explains its lower power draw. The AMD operates at 55 W TDP, while the Intel draws only 25 W, less than half. The clock speeds reflect this: AMD's base clock is 2.90 GHz with a 5.10 GHz boost, while Intel's base is 1.90 GHz with a 4.70 GHz boost. The AMD's higher clocks and 24 threads drive its multi-core dominance, but the Intel's smaller process and lower power allow it to sustain competitive single-thread performance with a 4.70 GHz boost.

Memory support differs: the AMD uses DDR5 with dual-channel and 83.2 GB/s bandwidth, while the Intel uses LPDDR5X with dual-channel and 136.5 GB/s bandwidth. The Intel's memory bandwidth is 64% higher, which contributes to its floating-point and physics wins despite lower compute throughput. PCIe connectivity also diverges: the AMD provides Gen 5 with 28 lanes, while the Intel offers Gen 5 with only 4 lanes. This makes the AMD far more suitable for discrete GPUs, NVMe storage, or expansion cards.

Integrated graphics differ as well: the AMD includes Radeon 610M, while the Intel includes Arc B390. The Intel's integrated GPU is likely more capable for light gaming or media tasks, though no benchmark data in the database covers iGPU performance. The AMD has an unlocked multiplier, while the Intel is locked. The AMD uses socket AMD FL1, and the Intel uses Intel BGA 2540. The AMD's transistor count is 13,140 million across a 2x 71 mm² die, while the Intel's transistor count and die size are not recorded.

The Verdict

The data supports the AMD Ryzen 7 8840HX as the clear choice for multi-threaded and integer-heavy workloads. Its 72.4% lead in Cinebench R23 multi-core and 105.9% lead in integer math leave no ambiguity: rendering, compilation, data processing, and any parallel workload will run substantially faster. The 24 threads versus 14, combined with higher clocks and 64 MB L3 cache, deliver a 36.1% multi-thread PassMark advantage. The AMD also holds a 94th percentile rank among all CPUs, compared to Intel's 85th, and its average benchmark score of 71797 dwarfs Intel's 36699.

The Intel Arc G3 EXTREME should be selected for scenarios where power efficiency and single-thread responsiveness are the primary constraints. Its 25 W TDP makes it suitable for fanless or ultra-portable designs, and its 7.8% single-thread lead in PassMark and 13.1% physics win indicate an edge in interactive or physics-based applications. The Intel also matches the AMD in floating-point math, with a 0.2% difference that is within noise. For users who prioritize battery life, low heat, or specific physics workloads, the Intel is defensible.

The average benchmark scores place the AMD at 71797, which sits near the Intel Core Ultra 7 265KF at 71910 (0.2% behind), while the Intel Arc G3 EXTREME at 36699 sits near the Intel Core Ultra 5 225 at 36938 (0.6% behind). This means the AMD competes with high-end desktop-class processors, while the Intel competes with mid-range desktop parts. The AMD's nearest rivals include the Intel Xeon Platinum 8270 at 71370 (0.6% ahead of AMD) and the Intel Xeon 6517P at 72350 (0.8% ahead), while the Intel's rivals include the AMD Ryzen 5 5600F at 36945 and the AMD Ryzen 5 5500X3D at 37018. The performance class difference is stark.
