AMD Ryzen AI 5 430 vs Intel Core 5 315 Comparison

The AMD Ryzen AI 5 430 and Intel Core 5 315 are both mobile processors aimed at thin-and-light laptops, but the benchmark data shows they are optimized for very different workloads. The Intel Core 5 315, based on the Wildcat Lake architecture with 6 cores and 6 threads, dominates the overall win count at 12 out of 15 head-to-head comparisons, while the AMD Ryzen AI 5 430, which uses 4 cores and 8 threads, takes only 3 wins. However, the AMD chip’s victories are significant and point to specific use cases where its design excels.

Where Each One Wins

The Intel Core 5 315 is the clear winner for pure multi-threaded throughput and compute-heavy tasks. In the Cinebench R23 multi-core test, the Intel chip scores 12981 against the AMD’s 8130, a 37.4% advantage. This pattern repeats in PassMark’s floating-point math, physics, and encryption workloads. The Intel part delivers 42441 in floating-point math versus 27193, and 1163 in physics versus 726. These results indicate that for video rendering, 3D simulation, and cryptographic workloads, the Intel Core 5 315 is the stronger choice. Its 6 physical cores, even without Hyper-Threading, provide a substantial raw execution advantage over the AMD’s 4 cores.

The AMD Ryzen AI 5 430, conversely, shows its strength in integer-heavy and data-organization tasks. Its largest win comes in PassMark integer math, scoring 39637 against Intel’s 31690, a 25.1% lead. It also wins in data compression with 158912 versus 146143, an 8.7% margin. These wins suggest that for software compilation, database operations, and general office productivity that relies on integer calculations, the AMD processor holds an edge. The single-core Cinebench R15 test is also an AMD win, scoring 269 versus 184, a massive 46.2% delta, indicating strong short-burst single-thread performance in legacy workloads.

For single-thread performance in more modern benchmarks, Intel takes the lead. The Cinebench R23 single-core score is 1832 for Intel and 1797 for AMD, a slim 1.9% margin. PassMark single-thread is also an Intel win at 4021 versus 3683. This makes the Intel processor more reliable for everyday responsiveness and applications that are not heavily multi-threaded. The data shows a split: Intel for multi-core and modern single-core, AMD for specific integer and compression tasks plus very fast legacy single-core bursts.

Architecture Differences

The two processors are built on fundamentally different silicon designs. The AMD Ryzen AI 5 430 uses the Gorgon Point codename and belongs to the Ryzen AI 400 generation, which combines Zen 5 and Zen 5c cores. It is fabricated by TSMC on a 4 nm process. The Intel Core 5 315 uses the Wildcat Lake codename and is built by Intel on a 3 nm node. This process difference is notable, though the benchmark results show that Intel’s larger core count compensates for any node advantage.

Core configuration is a major split. The AMD chip has 4 cores and 8 threads, utilizing simultaneous multi-threading to double its thread count. The Intel chip has 6 cores and 6 threads, with no multi-threading. This means the AMD part has more threads than cores, while the Intel part has equal numbers. Cache hierarchies also differ. AMD provides 80 KB of L1 cache per core, 1 MB of L2 per core, and a total of 4 MB of L3 cache. Intel offers 192 KB of L1 cache total, 2.5 MB of L2, and 6 MB of shared L3 cache. The larger shared L3 pool on the Intel chip likely contributes to its multi-core performance.

Memory architecture is another key difference. Both support DDR5 and LPDDR5X memory, but the AMD Ryzen AI 5 430 uses a dual-channel memory bus with a peak bandwidth of 89.6 GB/s. The Intel Core 5 315 uses a single-channel memory bus with a peak bandwidth of 59.7 GB/s. Despite this memory bandwidth disadvantage, the Intel chip still wins the majority of benchmarks, suggesting its core count is the dominant factor. The AMD processor supports ECC memory, while the Intel part does not. PCIe connectivity also differs, with AMD offering Gen 4 with 14 lanes and Intel offering Gen 4 with 6 lanes.

The integrated graphics are different as well. AMD uses the Radeon 840M, while Intel uses Xe3 Graphics with 2 Xe cores. The production status for both is Active, and neither has an unlocked multiplier. The AMD chip has a base clock of 2.00 GHz and a boost clock of 4.50 GHz, while the Intel chip has a base clock of 1.50 GHz and a boost clock of 4.40 GHz. The AMD part has a higher base clock, but the Intel part’s boost clock is close.

Head-to-Head Benchmarks

The Cinebench suite shows a stark contrast in performance scaling. In Cinebench R15 multi-core, Intel wins with 1308 against AMD’s 1195, an 8.6% lead. This is a modest win. In Cinebench R23 multi-core, Intel’s lead expands dramatically to 37.4%, scoring 12981 versus 8130. The R23 workload is longer and more demanding, which likely exposes the thermal and power delivery advantages of Intel’s 6-core design under sustained load. In single-core tests, the results are mixed. Cinebench R15 single-core is a decisive AMD win at 46.2%, but Cinebench R23 single-core flips to Intel by 1.9%. This suggests the AMD core is faster for very short, bursty workloads, but the Intel core is more efficient in longer single-threaded tasks.

The PassMark suite provides a broader view. The Intel chip wins in encryption by 31.7%, scoring 11119 versus 7591. It also wins in extended instructions by 12.8% and in find prime numbers by 60.7%, a massive delta. Prime number finding is a pure integer workload, but it is also heavily dependent on branch prediction and core count, which Intel’s 6-core design handles better. Floating-point math is an Intel win by 35.9%, and physics is an Intel win by 37.6%. Multithreaded performance is an Intel win by 12.8%, and random string sorting is an Intel win by 5.3%.

The AMD wins in PassMark are focused. Integer math is a 25.1% win, which is its largest margin. Data compression is an 8.7% win. These two results indicate that the Zen 5 architecture in the AMD chip has a strong integer execution unit and efficient compression algorithms. The overall average benchmark score reflects the aggregate performance: the AMD Ryzen AI 5 430 has an average score of 19617, while the Intel Core 5 315 has an average of 18188. This is an interesting discrepancy, as the Intel chip wins more individual tests, but the AMD chip has a higher average score. This indicates that the AMD chip’s wins are in tests that contribute more heavily to the average score metric, or that its losses are smaller in magnitude.
