AMD Ryzen AI 9 365 vs Intel Core 5 315 Comparison

Where Each One Wins

The benchmark data splits cleanly along workload types. The AMD Ryzen AI 9 365 dominates multi-threaded and compute-heavy tasks, winning 13 of the 15 recorded head-to-head comparisons. Its largest margins come in integer math, where it scores 101,831 against Intel's 31,690, a 221.3% advantage, and in data compression, where it reaches 354,510 versus 146,143, a 142.6% lead. These are not narrow victories; they represent fundamentally different throughput capabilities.

The Intel Core 5 315 takes the remaining two wins, both in single-thread PassMark evaluations. It posts 4,021 in PassMark single-thread and singlethread tests, while the AMD scores 3,841, a 4.5% edge. This is a modest but consistent advantage, suggesting the Intel part has slightly higher per-core efficiency in lightly threaded integer workloads, despite its lower clock ceiling.

For productivity workloads like Cinebench rendering, the AMD pulls ahead substantially. In Cinebench R23 multi-core, it scores 18,698 versus 12,981, a 44% lead. The single-core gap is far smaller: 1,992 versus 1,832, an 8.7% margin. This pattern repeats across the suite: the AMD wins by a little in single-threaded tasks and by a lot in multi-threaded ones. PassMark physics shows a 46.5% edge (1,704 versus 1,163), floating point math a 48% edge (62,802 versus 42,441), and multithread a 92.9% edge (29,467 versus 15,272).

The database places the AMD at the 87th percentile among all CPUs, while the Intel sits at the 72nd. The average benchmark score for the AMD is 40,048, compared to 18,188 for the Intel. The AMD's nearest rivals cluster around 40,000 average score, with deltas of -0.1% to -0.7% relative to the AMD. The Intel's nearest rivals hover near 18,180, with deltas of 0% to 0.1%. This places the two processors in entirely different performance tiers, not just different positions within a shared tier.

Architecture Differences

The two chips take fundamentally different design approaches. The AMD Ryzen AI 9 365 uses the Zen 5 architecture, specifically the Strix Point codename from the Ryzen AI 300 generation, which combines Zen 5 and Zen 5c cores. It is built on a 4 nm process at TSMC. The Intel Core 5 315 uses the Wildcat Lake codename from the Core 5 generation, built on a 3 nm process at Intel's own foundry.

Core counts differ sharply. The AMD provides 10 cores and 20 threads, while the Intel offers 6 cores and 6 threads. The Intel part has no simultaneous multithreading, so its thread count equals its core count. This explains much of the multi-threaded performance gap: the AMD has nearly double the cores and more than three times the threads.

Cache hierarchies also diverge. The AMD allocates 80 KB of L1 per core, 1 MB of L2 per core, and 16 MB of L3. The Intel uses 192 KB of L1 total, 2.5 MB of L2, and 6 MB of shared L3. The AMD's per-core L2 design gives each core dedicated fast memory, while the Intel consolidates its L2 into a smaller pool. The L3 difference is substantial: 16 MB versus 6 MB.

Memory architecture differs in a critical way. The AMD uses a dual-channel memory bus with 89.6 GB/s of bandwidth. The Intel uses a single-channel bus with 59.7 GB/s. Both support DDR5 and LPDDR5X, and neither supports ECC memory. The AMD's wider memory path provides 50% more theoretical bandwidth, which directly benefits multi-threaded workloads that stream data.

PCIe connectivity also favors the AMD. It offers Gen 4 with 16 CPU lanes, while the Intel provides Gen 4 with 6 CPU lanes. Integrated graphics differ as well: the AMD uses Radeon 880M, while the Intel uses Xe3 Graphics with 2 Xe cores. The AMD has a larger die at 233 mm², while the Intel's die size is not recorded. The AMD's socket is AMD Socket FP8; the Intel uses Intel BGA 1516.

Head-to-Head Benchmarks

The largest single margin in the entire comparison is PassMark integer math, where the AMD scores 101,831 against the Intel's 31,690, a 221.3% advantage. This workload measures raw integer arithmetic throughput, and the AMD's combination of more cores, more threads, and higher boost clock (5.00 GHz versus 4.40 GHz) produces an overwhelming lead.

Data compression shows a 142.6% gap: 354,510 versus 146,143. This workload is sensitive to both core count and memory bandwidth, and the AMD's dual-channel 89.6 GB/s configuration versus the Intel's single-channel 59.7 GB/s amplifies the core advantage. Random string sorting follows at 124.8% (39,447 versus 17,551), another memory-intensive task.

Cinebench R15 multi-core shows a 117.3% lead (2,842 versus 1,308), and PassMark multithread shows 92.9% (29,467 versus 15,272). Extended instructions score 91.1% higher on the AMD (25,113 versus 13,143). Data encryption shows 64.6% (18,297 versus 11,119), and Cinebench R15 single-core shows 64.7% (303 versus 184). The R15 single-core margin is notable because it is much larger than the R23 single-core margin of 8.7% (1,992 versus 1,832), suggesting the older benchmark is more sensitive to clock speed differences.

PassMark physics shows 46.5% (1,704 versus 1,163), floating point math shows 48% (62,802 versus 42,441), and Cinebench R23 multi-core shows 44% (18,698 versus 12,981). Find prime numbers shows the narrowest AMD win at 4.5% (117 versus 112).

The Intel's only wins are the two PassMark single-thread tests, both at 4,021 versus 3,841, a 4.5% advantage. This indicates that in a purely single-threaded integer workload, the Intel's architecture extracts slightly more performance per clock, even though its boost clock is 0.60 GHz lower. The AMD's 8.7% lead in Cinebench R23 single-core, however, shows that in rendering workloads, the AMD's higher clock and architecture win out.

Specification Differences

The specification table shows a clear separation in nearly every category. Core count: 10 versus 6. Thread count: 20 versus 6. Base clock: 2.00 GHz versus 1.50 GHz. Boost clock: 5.00 GHz versus 4.40 GHz. TDP: 28 W versus 15 W. The AMD draws more power but delivers far more compute.

Process node: 4 nm (TSMC) versus 3 nm (Intel). Cache: the AMD's 16 MB L3 versus the Intel's 6 MB shared L3; per-core L1 of 80 KB versus 192 KB total; per-core L2 of 1 MB versus 2.5 MB total. Memory bus: dual-channel versus single-channel, with 89.6 GB/s versus 59.7 GB/s. PCIe: Gen 4 with 16 lanes versus Gen 4 with 6 lanes. Socket: AMD Socket FP8 versus Intel BGA 1516. Integrated graphics: Radeon 880M versus Intel Xe3 Graphics (2 Xe). Die size: 233 mm² versus not recorded.

Release dates differ by nearly two years: the AMD launched on June 30, 2024, while the Intel launched on April 15, 2026. The Intel has a recorded launch MSRP of $340; the AMD has no recorded launch MSRP. Both are active production parts, both are mobile segment, both have locked multipliers, and neither supports ECC.
