Where Each One Wins

The benchmark data splits these two mobile processors along clear lines. The AMD Ryzen AI 5 330 takes 3 of the 15 recorded head-to-head tests, while the Intel Core 5 315 wins 12. That looks lopsided, but the AMD wins are concentrated in specific workloads where its architecture pulls ahead.

The AMD Ryzen AI 5 330 wins in data compression, integer math, and the Cinebench R15 single-core test. The data compression score of 152012 beats Intel's 146143 by 4%, which is a modest but real edge for archive handling and file packing. Integer math shows a larger gap: 37771 versus 31690, a 19.2% advantage. This points to strong ALU performance that benefits integer-heavy code, such as scripting, parsing, and database-style operations. The R15 single-core win is narrow at 199.9 versus 184, an 8.6% margin, indicating the AMD core can edge ahead in legacy single-threaded benchmarks.

The Intel Core 5 315 dominates nearly everything else. Its biggest wins come in multi-core workloads. The Cinebench R23 multi-core score of 12981 is 39.6% higher than AMD's 7840. That is the single largest delta in the entire comparison. The R15 multi-core test shows a smaller but consistent advantage at 1308 versus 1191, an 8.9% gap. PassMark multi-thread also favors Intel at 15272 versus 12797, a 16.2% difference. The floating-point math score of 42441 versus 26196 represents a 38.3% lead, which strongly favors scientific computing, rendering, and any workload relying on FPU throughput.

Intel also wins the encryption test decisively: 11119 versus 7251, a 34.8% margin. The extended instructions score goes to Intel at 13143 versus 11124, a 15.4% lead. Prime number finding shows Intel at 112 versus AMD's 42, a 62.5% gap, which suggests the Intel core's integer and branch handling is better suited to that specific sieve-style workload. Physics simulation also goes to Intel at 1163 versus 705, a 39.4% lead. Random string sorting favors Intel at 17551 versus 16188, a 7.8% edge. The single-thread PassMark score is Intel's at 4021 versus 3515, a 12.6% margin.

The Intel Core 5 315 is better for multi-core rendering, floating-point math, encryption, and general productivity. The single-core Cinebench R23 result is nearly tied: Intel at 1832 versus AMD at 1812, a 1.1% margin that falls within measurement noise. Both processors sit at the same percentile tier, with AMD at 73 and Intel at 72 percent of all CPUs in the database, so the overall performance class is similar despite the benchmark split.

Architecture Differences

The two chips use fundamentally different designs. The AMD Ryzen AI 5 330 is built on the Zen 5 architecture with the Krackan Point 2 codename, part of the Ryzen AI 300 generation that mixes Zen 5 and Zen 5c cores. It has 4 cores and 8 threads, meaning each core supports two threads via SMT. The process node is 4 nm from TSMC. The Intel Core 5 315 uses the Wildcat Lake codename with a 3 nm process from Intel's own foundry. It has 6 cores but only 6 threads, so no hyper-threading is present. This is a core count advantage for Intel, but a thread count tie at 8 versus 6? No, AMD has 8 threads, Intel has 6, so Intel trades thread count for more physical cores.

The cache layouts differ significantly. AMD uses an 80 KB L1 per core, a 1 MB L2 per core, and only 4 MB of L3 total. Intel uses 192 KB of L1, 2.5 MB of L2, and 6 MB of shared L3. The larger L3 on Intel likely contributes to its multi-core and encryption wins, since more shared cache reduces memory traffic. The memory bus is also different: AMD is dual-channel with 89.6 GB/s bandwidth, while Intel is single-channel with 59.7 GB/s. Despite the lower memory bandwidth, Intel still wins most benchmarks, suggesting its core efficiency compensates.

The integrated graphics differ as well. AMD includes a Radeon 820M, while Intel has Xe3 Graphics with 2 Xe cores. PCIe support shows AMD with Gen 4 and 14 lanes, versus Intel with Gen 4 and only 6 lanes. Both are mobile processors with active production status. The AMD part releases in July 2025, the Intel part in April 2026. Neither has an unlocked multiplier. ECC memory is not supported on either. Both support DDR5 and LPDDR5X memory. The AMD TDP is 28 watts, while the Intel TDP is 15 watts, so the Intel part is rated for lower power draw. The base clocks differ: AMD at 2.00 GHz, Intel at 1.50 GHz. Boost clocks are close: AMD at 4.50 GHz, Intel at 4.40 GHz.

The Verdict

The data points to a clear division of roles. The Intel Core 5 315 is the stronger multi-core and floating-point processor, winning 12 of 15 head-to-head tests. It delivers a 39.6% lead in Cinebench R23 multi-core, a 38.3% lead in floating-point math, and a 34.8% lead in encryption. Its 6 physical cores and 6 MB of shared L3 cache, combined with a lower 15 W TDP, make it the better choice for rendering, scientific workloads, and any parallel task that scales with cores.

The AMD Ryzen AI 5 330 is the better integer processor. Its 19.2% win in integer math and 4% win in data compression show strength in general-purpose code, file handling, and ALU-bound tasks. The 8.6% win in R15 single-core suggests the Zen 5 core has solid legacy single-thread performance. The average benchmark score of 18811 versus 18188 also favors AMD, meaning its wins, while fewer, are concentrated in areas that lift the overall average.

For a buyer choosing between these two, the decision hinges on workload. The Intel part is the default for multi-threaded productivity and compute-heavy tasks. The AMD part suits integer-focused work and light compression duties. Both are mobile processors in active production, with the AMD launching July 2025 and the Intel launching April 2026. The Intel launch MSRP is $340. Neither supports ECC, neither has an unlocked multiplier, and both use DDR5 or LPDDR5X memory. The AMD has more PCIe lanes at 14 versus 6, and a dual-channel memory bus versus single-channel. The Intel has a newer 3 nm process and more physical cores. The recorded data gives the Intel part the majority of wins, but the AMD part holds a higher average score and specific strengths that matter in integer-heavy environments.
