AMD Ryzen AI 5 PRO 340 vs Intel Core 5 315 Comparison

Where Each One Wins

The benchmark record splits almost evenly, with the AMD Ryzen AI 5 PRO 340 taking 8 wins and the Intel Core 5 315 taking 7. The division is not random: it maps cleanly onto workload type, threading behavior, and instruction-level efficiency.

The AMD processor wins decisively in integer-heavy and data-movement tasks. Its largest margin is in PassMark integer math, where it scores 63233 against 31690, a 99.5% lead. Data compression shows a 51.6% advantage (221581 versus 146143). Random string sorting goes to AMD by 38.6% (24334 versus 17551). Extended instructions favor AMD by 19.6% (15721 versus 13143). Multithreaded PassMark shows AMD ahead by 25.8% (19215 versus 15272). Encryption is nearly tied but still goes to AMD, 11212 versus 11119, a 0.8% edge. In Cinebench R15, AMD wins both multi-core (1743 versus 1308, 33.3% ahead) and single-core (276 versus 184, 50% ahead).

The Intel processor wins in several single-threaded and specialized math workloads. Cinebench R23 multi-core goes to Intel, 12981 versus 11534, an 11.1% margin. Cinebench R23 single-core also goes to Intel, 1832 versus 1802, a 1.6% edge. PassMark single-thread favors Intel, 4021 versus 3758, a 6.5% lead. Floating-point math goes to Intel, 42441 versus 39662, a 6.5% margin. Prime number finding shows Intel at 112 versus 74, a 33.9% advantage. Physics simulation goes to Intel, 1163 versus 1084, a 6.8% lead.

The pattern suggests AMD holds the advantage when workloads scale across threads and involve integer manipulation or memory movement. Intel counters in workloads that favor higher per-core frequency behavior and floating-point throughput, despite having fewer threads.

Architecture Differences

The two processors take fundamentally different design paths. AMD uses Zen 5 architecture on a 4 nm TSMC process, with the Krackan Point codename and a 195 mm² die. Intel uses the Wildcat Lake codename on a 3 nm Intel process. Both are mobile parts with active production status, but the underlying structures diverge sharply.

Both have 6 cores, but AMD provides 12 threads while Intel provides 6. AMD implements simultaneous multithreading; Intel does not. Base clocks differ: AMD starts at 2.00 GHz and boosts to 4.80 GHz. Intel starts at 1.50 GHz and boosts to 4.40 GHz. Intel has a lower TDP at 15 versus AMD's 28.

Cache layouts are not comparable in the same terms. AMD lists 80 KB L1 per core, 1 MB L2 per core, and 8 MB L3. Intel lists 192 KB L1 total, 2.5 MB L2 total, and 6 MB shared L3. The AMD per-core L2 design gives each core a private 1 MB slice, while Intel pools a smaller total L2. AMD's L3 is larger at 8 MB versus 6 MB.

Memory architecture differs substantially. Both support DDR5 and LPDDR5X, but AMD uses a dual-channel memory bus with 89.6 GB/s bandwidth, while Intel uses a single-channel bus with 59.7 GB/s. That 33% bandwidth gap appears in the data-compression and random-string-sorting results. AMD also supports ECC memory; Intel does not.

PCIe lanes differ: AMD provides Gen 4 with 16 lanes (CPU only), Intel provides Gen 4 with 6 lanes (CPU only). Integrated graphics differ: AMD uses Radeon 840M, Intel uses Xe3 Graphics with 2 Xe cores. Sockets are incompatible: AMD Socket FP8 versus Intel BGA 1516. Neither processor has an unlocked multiplier.

Release dates differ. AMD entered the database on 2025-01-05. Intel's release date is listed as 2026-04-15. Intel carries a launch MSRP of $340. AMD has no launch MSRP in the record.

The Verdict

The data supports a clear split by workload priority. The AMD Ryzen AI 5 PRO 340 is the stronger choice for multithreaded integer work, data compression, encryption, and any task that benefits from 12 threads. Its 99.5% lead in integer math and 51.6% lead in data compression are the largest margins in the head-to-head set. The dual-channel memory bus at 89.6 GB/s aligns with its wins in memory-intensive sorting and compression. The 12 threads give it a 25.8% multithread PassMark advantage.

The Intel Core 5 315 wins in single-threaded performance, floating-point math, prime number finding, and physics simulation. Its 4021 PassMark single-thread score beats AMD's 3758. Its Cinebench R23 multi-core score of 12981 actually beats AMD's 11534 despite having half the threads, which indicates very strong per-core efficiency in that specific rendering workload. The 3 nm process and 4.40 GHz boost clock contribute to that profile.

For users prioritizing integer throughput, compression, encryption, or heavily threaded productivity, the AMD part is the indicated choice. For users prioritizing single-thread responsiveness, floating-point workloads, or lower power draw (15 W TDP versus 28 W), the Intel part holds the advantage. The overall average benchmark score favors AMD: 27932 versus 18188. AMD also sits at the 80th percentile of all CPUs, while Intel sits at the 72nd. The nearest-rival data places AMD alongside desktop-class parts like the Ryzen 7 5800X3D (0.1% delta) and Core i9-10900K (0.2% delta), while Intel sits alongside the Core i7-9700 and Ryzen 7 5700U (both 0% delta). That placement reinforces the performance tier difference.

Head-to-Head Benchmarks

The largest AMD win is PassMark integer math. The score difference of 31543 points (63233 versus 31690) translates to a 99.5% delta, nearly double the Intel result. This workload stresses arithmetic throughput and thread scaling, where AMD's 12 threads provide a structural advantage.

Data compression shows a 51.6% AMD lead. The 221581 score versus 146143 indicates strong memory bandwidth utilization, consistent with AMD's dual-channel 89.6 GB/s bus versus Intel's single-channel 59.7 GB/s. Random string sorting follows the same pattern: AMD leads 38.6% (24334 versus 17551), another memory-movement workload.

Cinebench R15 multi-core gives AMD a 33.3% win (1743 versus 1308). The single-core R15 result is even more lopsided: AMD leads 50% (276 versus 184). These older Cinebench versions appear to favor AMD's architecture more than R23 does.

PassMark multithread shows AMD ahead 25.8% (19215 versus 15272). Extended instructions favor AMD by 19.6% (15721 versus 13143). Data encryption is nearly even, AMD at 11212 versus Intel at 11119, a 0.8% margin.

The largest Intel win is PassMark find prime numbers. Intel scores 112 versus AMD's 74, a 33.9% lead. This workload is highly single-threaded and latency-sensitive, where Intel's higher single-thread score matters.

Cinebench R23 multi-core goes to Intel by 11.1% (12981 versus 11534). This is the only multi-core rendering test Intel wins, and it does so despite having 6 fewer threads. The result suggests Intel's per-core efficiency in this specific workload is substantially higher.

PassMark physics gives Intel a 6.8% edge (1163 versus 1084). Floating-point math also goes to Intel by 6.5% (42441 versus 39662). Single-thread PassMark shows Intel at 4021 versus 3758, a 6.5% margin. Cinebench R23 single-core is the closest Intel win at 1.6% (1832 versus 1802).

Across the full head-to-head set, AMD wins 8 tests and Intel wins 7. The average benchmark score confirms AMD's overall lead: 27932 versus 18188, a difference of 9744 points.

The socket difference makes these incompatible in any system. The thread count difference is the most consequential specification for multithreaded workloads. The memory bandwidth gap of 29.9 GB/s (89.6 versus 59.7) explains the compression and sorting deltas. The TDP difference of 13 W (28 versus 15) indicates Intel targets lower-power designs. Intel's 3 nm process is one node step ahead of AMD's 4 nm. Both use Gen 4 PCIe, but AMD offers 10 more lanes. ECC support is exclusive to AMD. The release dates are over a year apart, with AMD first.
