AMD Ryzen AI 7 445 vs Intel Core 5 315 Comparison

The Verdict

The recorded data separates these two mobile processors into distinct roles. The AMD Ryzen AI 7 445 wins 7 of the 15 head-to-head benchmark comparisons, while the Intel Core 5 315 wins 8. The AMD part holds a higher overall percentile rank at 79 versus Intel's 72, and its average benchmark score of 26936 far exceeds Intel's 18188. However, the Intel chip counters with superior single-thread performance and a dramatically better result in Cinebench R23 multi-core.

The AMD Ryzen AI 7 445 is the choice for users prioritizing multi-threaded throughput, integer math, compression, and sorting workloads. It delivers an 84.1% lead in PassMark integer math, a 47.7% lead in data compression, and an 18.6% lead in the PassMark multi-thread test. Its 6 cores and 12 threads provide clear advantages in parallel tasks.

The Intel Core 5 315 is the pick for single-thread responsiveness and specific floating-point or physics workloads. It leads by 10.7% in PassMark single-thread, by 7.3% in floating-point math, and by 16.1% in physics. Its Cinebench R23 multi-core score of 12981 is 18.4% ahead of AMD's 10590, which is an outlier given AMD's wins elsewhere.

Where Each One Wins

The AMD Ryzen AI 7 445 dominates in integer-heavy and data-processing benchmarks. Its PassMark integer math score of 58332 is nearly double Intel's 31690. Data compression shows a 47.7% advantage (215812 versus 146143), and random string sorting favors AMD by 33.8% (23488 versus 17551). Extended instructions also go to AMD with a 20.4% margin (15826 versus 13143). The Cinebench R15 tests heavily favor AMD: 31.7% ahead in multi-core (1723 versus 1308) and 38% ahead in single-core (254 versus 184).

The Intel Core 5 315 wins in the newer Cinebench R23 tests, where its multi-core score reaches 12981 compared to AMD's 10590, an 18.4% margin. Single-core R23 is close but favors Intel: 1832 versus 1806, a 1.4% difference. PassMark single-thread shows Intel at 4021 versus AMD's 3591, a 10.7% lead. Intel also wins in find prime numbers with a score of 112 versus AMD's 56, a 50% margin. Floating-point math (42441 versus 39362, a 7.3% lead), physics (1163 versus 976, a 16.1% lead), and data encryption (11119 versus 10519, a 5.4% lead) all go to Intel.

Head-to-Head Benchmarks

The largest margin in either direction belongs to AMD in PassMark integer math. The Ryzen AI 7 445 scores 58332 against Intel's 31690, an 84.1% lead. This is the definitive separation point: AMD crushes integer operations, which explains its wins in data compression (215812 versus 146143, up 47.7%) and random string sorting (23488 versus 17551, up 33.8%).

Intel's biggest win is in PassMark find prime numbers, where it scores 112 versus AMD's 56, a 50% margin. This is a prime-number calculation test that often rewards specific instruction patterns. Intel also wins Cinebench R23 multi-core by 18.4%, scoring 12981 versus 10590, which is surprising given AMD's 31.7% win in Cinebench R15 multi-core (1723 versus 1308). The R15 and R23 results suggest the two chips scale very differently across workload versions.

In single-core tests, the pattern is inconsistent. AMD wins Cinebench R15 single-core by 38% (254 versus 184), but Intel wins PassMark single-thread by 10.7% (4021 versus 3591) and Cinebench R23 single-core by 1.4% (1832 versus 1806). The Intel chip appears stronger in newer single-thread workloads, while AMD dominates the older R15 test.

Intel takes the physics test with 1163 versus AMD's 976, a 16.1% lead, and floating-point math with 42441 versus 39362, a 7.3% lead. Data encryption goes to Intel by 5.4% (11119 versus 10519). AMD counters with extended instructions at 15826 versus 13143, a 20.4% lead, and the PassMark multi-thread test at 18115 versus 15272, an 18.6% lead.

The overall win count is 8 for Intel and 7 for AMD, but the magnitude of AMD's wins is often larger. AMD's biggest single margin is 84.1%, while Intel's biggest is 50%. AMD also holds a 79th percentile rank versus Intel's 72nd, and its average benchmark score of 26936 is roughly 48% higher than Intel's 18188. The data indicates AMD is the stronger overall processor despite losing more individual comparisons.
