AMD Ryzen AI 5 PRO 440 vs Intel Core 3 305 Comparison

Head-to-Head Benchmarks

The recorded PassMark suite shows a decisive overall advantage for the AMD Ryzen AI 5 PRO 440, which takes 7 of the 11 head-to-head tests. The largest margin comes in integer math, where AMD scores 65,991 against Intel's 32,295, a 104.3% advantage. Data compression follows with AMD at 256,420 versus 146,857, a 74.6% lead. Random string sorting also favors AMD by 54.6% (27,252 vs. 17,623). Extended instructions show a 36.3% gap (18,456 vs. 13,543), while multithread performance lands at 36.4% ahead (21,054 vs. 15,439). The AMD part also wins data encryption by 12.7% (12,418 vs. 11,019) and floating-point math by a narrower 1.5% (42,934 vs. 42,284).

The Intel Core 3 305 claims four wins, but the margins are smaller and more situational. In find prime numbers, Intel scores 115 versus AMD's 77, a 33% lead. Physics shows Intel ahead by 9.2% (1,233 vs. 1,119). Single-thread performance favors Intel by 4.8% in both recorded single-thread tests: 3,977 versus 3,785. These wins suggest Intel holds an edge in workloads that rely heavily on a single core or specific integer operations. However, the aggregate benchmark score tells a different story: AMD averages 41,208 across all tests, while Intel averages 18,302. That places AMD in the 87th percentile of all CPUs versus Intel's 72nd percentile.

Context from the nearest rivals reinforces the gap. The AMD part sits within 0.6% of the Intel Core Ultra X7 358H (40,967) and within 0.4% of the AMD Ryzen 9 5900X (41,376). The Intel Core 3 305, by contrast, matches the Intel Core i3-14100 (18,318) within 0.1% and sits 0.4% above the AMD Ryzen 5 2600E (18,230). In other words, the AMD Ryzen AI 5 PRO 440 competes in a performance class roughly 125% higher than the Intel Core 3 305 based on average benchmark scores.

Architecture Differences

The two processors diverge fundamentally in core topology. The AMD Ryzen AI 5 PRO 440 provides 6 cores and 12 threads, while the Intel Core 3 305 provides 6 cores and 6 threads. This thread advantage directly explains much of AMD's multithread and data-compression lead. The AMD architecture is Zen 5 under the Gorgon Point codename, part of the Ryzen AI PRO 400 generation that mixes Zen 5 and Zen 5c cores. The Intel part uses the Wildcat Lake codename in the Core 3 generation, with no architecture name recorded.

Process technology also differs. AMD uses a 4 nm node from TSMC, while Intel uses a 3 nm node from Intel's own foundry. Despite Intel's smaller process node, the AMD part carries a larger die at 195 mm²; Intel's die size is not recorded. Cache hierarchies are quite different as well. AMD allocates 80 KB of L1 per core and 1 MB of L2 per core, with 8 MB of shared L3. Intel specifies 192 KB of L1 total, 2.5 MB of L2, and 6 MB of shared L3. The per-core L2 on AMD (1 MB) is substantial, while Intel's total L2 of 2.5 MB across six cores is modest by comparison.

Memory architecture shows another clear split. AMD supports dual-channel DDR5 and LPDDR5X with a recorded memory bandwidth of 89.6 GB/s. Intel also supports DDR5 and LPDDR5X, but only in a single-channel configuration, yielding 59.7 GB/s. That 33% bandwidth deficit shows up in memory-sensitive workloads. AMD also supports ECC memory; Intel does not. PCIe capabilities differ: AMD provides Gen 4 with 16 lanes (CPU only), while Intel provides Gen 4 with 6 lanes (CPU only). Integrated graphics differ as well: AMD uses the Radeon 840M, Intel uses the Xe3 Graphics with 1 Xe core.

Clock speeds favor AMD on both ends. The AMD part runs at a 2.00 GHz base and 4.80 GHz boost, versus Intel's 1.50 GHz base and 4.30 GHz boost. Thermal design power also differs: AMD is rated at 28 W, Intel at 15 W. That 13 W difference means Intel draws less power, but the AMD part delivers higher performance within a mobile segment that tolerates slightly higher TDP.

The Verdict

The benchmark data positions the AMD Ryzen AI 5 PRO 440 in a clearly higher performance tier than the Intel Core 3 305. The average benchmark score of 41,208 versus 18,302 places them in different competitive neighborhoods: AMD's nearest rivals include the Intel Core Ultra 7 356H (41,215) and AMD Ryzen 9 5900X (41,376), while Intel's nearest rivals are the Intel Core i3-14100 (18,318) and Intel Core 5 330 (18,345). A system builder seeking multithread throughput, memory bandwidth, or ECC support should select the AMD part. The dual-channel memory bus (89.6 GB/s), 12 threads, and 104.3% integer math lead are decisive for compute-heavy mobile workloads.

The Intel Core 3 305 appeals where single-thread performance and power draw matter more than raw throughput. Its 15 W TDP is nearly half of AMD's 28 W, and it wins single-thread tests by 4.8%. The physics test also favors Intel by 9.2%. For lightweight mobile tasks, battery-conscious designs, or workloads dominated by single-core responsiveness, the Intel part holds advantages. Its 3 nm Intel process node also represents a smaller transistor geometry, though the practical performance data shows AMD's larger 4 nm TSMC part winning the majority of tests.

The 7-to-4 win count in the head-to-head suite understates the overall margin, since AMD's wins include the largest deltas (104.3% and 74.6%) while Intel's wins cap at 33%. The percentile ranks confirm the separation: 87th versus 72nd. Neither processor has an unlocked multiplier, so overclocking headroom is not a differentiator. The Intel part carries a launch MSRP of $309; AMD's launch MSRP is not recorded. Based strictly on recorded measurements, the AMD Ryzen AI 5 PRO 440 delivers more performance per watt in multithreaded scenarios, while the Intel Core 3 305 offers better single-thread results and a lower power envelope.
