AMD Ryzen AI 7 345 vs Intel Core 5 315 Comparison

Head-to-Head Benchmarks

The benchmark data splits cleanly between AMD and Intel, with the AMD Ryzen AI 7 345 taking 9 of 15 head-to-head tests while the Intel Core 5 315 wins 6. The margins, however, are heavily lopsided in AMD's favor. The Ryzen AI 7 345 dominates in integer math, scoring 63,475 against the Intel's 31,690, a 100.3% advantage. That is the single largest gap in the entire comparison. Data compression shows a similar story: AMD scores 237,484 versus Intel's 146,143, a 62.5% lead. Random string sorting also favors AMD by 44.9% (25,435 versus 17,551). The AMD chip leads in extended instructions by 29.4% (17,003 versus 13,143), multithread by 30.5% (19,927 versus 15,272), and Cinebench R15 multi-core by 30.9% (1,712 versus 1,308). The single-core R15 gap is even more pronounced: AMD wins 271 to 184, a 47.3% margin.

Intel's wins are narrower but still meaningful. The Core 5 315 takes Cinebench R23 multi-core with 12,981 versus AMD's 11,461, an 11.7% advantage. It also wins the prime number test by a substantial 44.6% (112 versus 62). In floating-point math, the two are nearly tied, with AMD at 42,621 and Intel at 42,441, a 0.4% difference. Intel edges out AMD in Cinebench R23 single-core (1,832 versus 1,818, a 0.8% lead), PassMark single-thread (4,021 versus 3,875, a 3.6% lead), and PassMark physics (1,163 versus 1,089, a 6.4% lead). Data encryption is close, with AMD ahead by just 6.3% (11,814 versus 11,119).

The average benchmark scores tell a broader story. AMD's overall average is 29,461, which places it at the 81st percentile of all CPUs in the database. Intel's average is 18,188, sitting at the 72nd percentile. AMD's nearest rivals by average score include the AMD Ryzen 7 3800X (29,447, 0% delta), the AMD EPYC 9654 (29,409, 0.2% delta), and the Intel Core i5-13500HX (29,270, 0.7% delta). Intel's nearest rivals include the AMD EPYC 9274F (18,189, 0% delta), the Intel Core i7-9700 (18,180, 0% delta), and the Intel Core i7-1365U (18,177, 0.1% delta). This means the Ryzen AI 7 345 competes at a performance tier roughly 62% higher than the Core 5 315 on average, based on the delta between their average scores.

The Verdict

The data indicates two distinct performance profiles. The AMD Ryzen AI 7 345 is the stronger overall processor, with its average benchmark score of 29,461 far exceeding Intel's 18,188. Its 12 threads versus Intel's 6 threads provide a clear advantage in throughput-oriented workloads. The 100.3% lead in integer math and 62.5% lead in data compression show that any workload relying on arithmetic or data processing will favor AMD. The multithread score of 19,927 versus 15,272 confirms this pattern. For users running compiled code, database operations, encryption tasks, or any parallel compute, the Ryzen AI 7 345 is the choice based on these measurements.

The Intel Core 5 315 wins in specific niches. Its 44.6% lead in prime number finding suggests strong performance in workloads that stress single-threaded integer loops with low memory pressure. The physics score of 1,163 versus 1,089 indicates a slight edge in simulation or physics-based tasks. The single-thread score of 4,021 versus 3,875 shows Intel has the faster single core in PassMark's test, even though AMD wins Cinebench R15 single-core by a wide margin. This inconsistency suggests the two chips respond differently to different instruction mixes. The Intel chip also wins Cinebench R23 multi-core, which is notable given its thread disadvantage, indicating efficient scaling in that specific workload.

The percentile rankings reinforce the verdict. AMD at the 81st percentile versus Intel at the 72nd percentile means the Ryzen AI 7 345 outperforms a larger share of the CPU population. The Intel Core 5 315, however, sits close to the AMD Ryzen 7 5700U (18,176 average, 0.1% delta) and Intel Core i7-1365U (18,177, 0.1% delta), placing it in a mid-range mobile performance bracket. The AMD chip's nearest rivals are all higher-tier desktop or mobile HX parts, including the Ryzen 7 3800X and Core i5-13500HX, showing it belongs in a faster class.

Where Each One Wins

The AMD Ryzen AI 7 345 wins in workloads that demand parallel throughput. Its 12 threads and dual-channel memory give it a clear edge in integer math (100.3% lead), data compression (62.5% lead), random string sorting (44.9% lead), and multithread performance (30.5% lead). Extended instructions also favor AMD by 29.4%, indicating better SIMD or specialized instruction handling. The encryption score (6.3% lead) and floating-point math (0.4% lead) show AMD is also competitive in those areas, though the margins are smaller. The Cinebench R15 multi-core result (30.9% lead) confirms AMD's strength in older multi-threaded rendering workloads.

The Intel Core 5 315 wins in specific single-threaded or low-thread-count scenarios. The prime number finding test (44.6% lead) suggests strong performance in tight integer loops. The physics test (6.4% lead) indicates an edge in simulation or physics calculation workloads. The PassMark single-thread score (3.6% lead) and Cinebench R23 single-core (0.8% lead) show Intel has a slight single-core advantage in certain newer tests. The Cinebench R23 multi-core result (11.7% lead) is the outlier, where Intel wins despite having half the threads, indicating that this particular workload scales better on Intel's architecture. For users prioritizing battery life, the Intel chip's 15-watt TDP versus AMD's 28-watt TDP suggests lower power consumption, though the database provides no efficiency benchmarks to quantify this. For users prioritizing raw compute throughput, the AMD chip's benchmark record makes it the clear choice.
