AMD Ryzen AI 7 450 vs Intel Core 5 315 Comparison

AMD Ryzen AI 7 450 and Intel Core 5 315 are both active mobile processors, but the benchmark data shows them occupying very different performance tiers. The AMD part, built on Zen 5, delivers substantially higher throughput in nearly every recorded workload, while the Intel part, based on Wildcat Lake, counters with a narrow but consistent advantage in specific single-threaded and integer-prime tests. The gap in average benchmark scores is wide: AMD's 39485 versus Intel's 18188. This places the Ryzen AI 7 450 in the 87th percentile of all CPUs, while the Core 5 315 sits in the 72nd percentile. The following sections break down where each processor wins, what architectural choices explain those results, and how the head-to-head measurements stack up.

Where Each One Wins

The AMD Ryzen AI 7 450 wins 12 of the 15 recorded head-to-head comparisons, and most of those victories are by large margins. The biggest separation appears in integer-heavy and multi-threaded workloads. In PassMark integer math, the AMD part scores 88531 against Intel's 31690, a 179.4% advantage. Data compression shows a 116.2% lead (315906 versus 146143), and random string sorting goes to AMD by 103.1% (35648 versus 17551). These are not marginal wins; they indicate a processor with roughly double the throughput in tasks that depend on parallel execution and memory bandwidth. Cinebench R23 multicore confirms the pattern: AMD scores 18316 versus 12981, a 41.1% lead, while Cinebench R15 multicore shows an even larger 107.4% gap (2713 versus 1308).

The Intel Core 5 315 wins only three recorded comparisons, and all three are narrow. PassMark single-thread gives Intel 4021 versus AMD's 3901, a 3% edge. The same result appears in the duplicate PassMark singlethread entry. The third win is in PassMark find prime numbers, where Intel scores 112 against AMD's 89, a 20.5% advantage. That prime-number test is the only workload where Intel's lead exceeds single digits. In every other measured category, AMD is ahead, often by double-digit percentages. The data therefore supports a clear split: AMD dominates multi-threaded, memory-intensive, and encryption workloads, while Intel shows a small but real edge in basic single-thread execution and a specific prime-number calculation routine.

Architecture Differences

The two processors diverge sharply at the architectural level. The AMD Ryzen AI 7 450 uses a Zen 5 design from the Gorgon Point generation, manufactured on a 4 nm process at TSMC. It has 8 cores and 16 threads, with a base clock of 2.00 GHz and a boost clock of 5.10 GHz. The cache hierarchy consists of 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of L3. The Intel Core 5 315, by contrast, comes from the Wildcat Lake generation and uses a 3 nm process at Intel. It has 6 cores and 6 threads, with a base clock of 1.50 GHz and a boost clock of 4.40 GHz. Its cache layout is 192 KB of L1, 2.5 MB of L2, and 6 MB of shared L3.

Threading is a major differentiator. AMD's 16 threads give it a direct parallel-compute advantage over Intel's 6 threads, which helps explain the multicore benchmark results. The Intel part lacks simultaneous multithreading entirely, so its 6 cores yield only 6 threads. Clock speeds also favor AMD: a 5.10 GHz boost versus 4.40 GHz. Memory access further separates the two. AMD uses a dual-channel memory bus with 89.6 GB/s of bandwidth and supports ECC memory. Intel uses a single-channel bus with 59.7 GB/s and does not support ECC. In bandwidth-sensitive workloads like data compression and random string sorting, that difference likely contributes to AMD's large leads.

Both CPUs support DDR5 and LPDDR5X memory and both use PCIe Gen 4, but lane counts differ. AMD provides 16 CPU lanes, while Intel provides 6. Integrated graphics also differ: AMD uses the Radeon 860M, while Intel uses Xe3 Graphics with 2 Xe cores. The AMD die measures 195 mm²; no die size is recorded for Intel. Power targets are distinct as well: AMD is rated at 28 W TDP, Intel at 15 W TDP. The Intel part has a launch MSRP of $340. Neither processor has an unlocked multiplier.

The Verdict

The recorded data points to a straightforward conclusion for most workloads: the AMD Ryzen AI 7 450 is the stronger processor by a wide margin. Its average benchmark score of 39485 is more than double Intel's 18188, and it holds the 87th percentile ranking versus Intel's 72nd. In multi-threaded rendering, integer math, encryption, compression, and floating-point math, AMD leads by margins ranging from 28.3% to 179.4%. For any task that scales across cores or depends on memory bandwidth, the Ryzen AI 7 450 is the clear choice based on this dataset.

The Intel Core 5 315 does have one legitimate area of advantage: single-thread performance. Its PassMark single-thread score of 4021 edges out AMD's 3901, and its find-prime-numbers result is 20.5% higher. That suggests Intel's core design, despite lower clocks and fewer threads, executes certain single-threaded instruction sequences more efficiently. The 3 nm process node and the Wildcat Lake core layout likely play a role, though the recorded data does not specify the underlying microarchitecture details beyond the codename and process.

For a system where the workload is heavily single-threaded and the power envelope is tight, the Intel part offers a narrow edge in a few specific tests. For everything else, the AMD part delivers between roughly 11% and 179% more performance depending on the workload. The percentile rankings reinforce this: being in the 87th percentile versus the 72nd percentile places the AMD processor in a higher overall performance class. The verdict from the data is that the AMD Ryzen AI 7 450 is the better all-around processor, with the Intel Core 5 315 retaining a niche lead in isolated single-thread and prime-number workloads.

Head-to-Head Benchmarks

The largest single win for AMD comes in PassMark integer math. AMD scores 88531 against Intel's 31690, a 179.4% advantage. This is the most lopsided result in the entire comparison and reflects the combined effect of more threads, higher clocks, and a wider memory bus. Data compression follows closely: AMD's 315906 versus Intel's 146143, a 116.2% lead. Random string sorting shows a 103.1% gap (35648 versus 17551), another bandwidth-heavy workload where AMD's dual-channel memory and higher thread count pay off. Extended instructions also favor AMD by 70.4% (22400 versus 13143), and PassMark multithread goes to AMD by 72.5% (26350 versus 15272).

In Cinebench tests, AMD's lead is substantial but narrower than in the PassMark integer tests. Cinebench R23 multicore shows AMD at 18316 versus Intel's 12981, a 41.1% gap. Cinebench R15 multicore is more extreme at 107.4% (2713 versus 1308). Single-core Cinebench results are closer: R23 single-core gives AMD 2038 versus 1832, an 11.2% lead, while R15 single-core gives AMD 215 versus 184, a 16.8% lead. PassMark physics also goes to AMD by 35.7% (1578 versus 1163), and floating-point math favors AMD by 28.3% (54447 versus 42441). Data encryption shows AMD ahead by 46.1% (16247 versus 11119).

The Intel wins are concentrated in two areas. PassMark find prime numbers gives Intel 112 versus AMD's 89, a 20.5% edge. This is Intel's largest winning margin. PassMark single-thread shows Intel at 4021 versus AMD's 3901, a 3% lead, and the duplicate singlethread entry records the same result. The overall win count is 12 for AMD and 3 for Intel. The average benchmark scores tell the same story: AMD at 39485 versus Intel's 18188. The nearest-rival data for AMD places it close to the AMD Ryzen 7 PRO 8840HS (delta -0.3%), the AMD Ryzen 7 PRO 8845HS (delta 0.4%), the AMD EPYC 4245P (delta 0.7%), and the AMD Ryzen 7 9800X3D (delta -0.7%). Intel's nearest rivals include the AMD EPYC 9274F (delta 0%), the Intel Core i7-9700 (delta 0%), the Intel Core i7-1365U (delta 0.1%), and the AMD Ryzen 7 5700U (delta 0.1%). Those rival comparisons confirm that both processors sit in established performance bands, but the bands themselves are far apart.
