AMD Ryzen AI 7 345 vs Intel Core i5-14450HX Comparison

Head-to-Head Benchmarks

The recorded head-to-head data shows a dominant result for the Intel Core i5-14450HX, which wins 13 of the 15 compared tests. The AMD Ryzen AI 7 345 wins only two, both in single-thread PassMark tests. The scale of Intel's victory varies widely depending on the workload, from narrow margins in extended instructions to a crushing 43% deficit in Cinebench R23 multi-core.

The largest single gap appears in Cinebench R23 multi-core, where the Intel part scores 20,108 against the AMD chip's 11,461, a delta of -43%. This is the headline result for heavily threaded rendering workloads. The Intel chip's advantage narrows in Cinebench R15 multi-core, where it posts 2,026 versus 1,712, a 15.5% lead. The pattern suggests the Intel processor's additional cores and threads translate into substantial scaling in multi-threaded compute, while the AMD processor's efficiency-oriented design cannot match that throughput.

Single-core results are closer but still favor Intel. In Cinebench R15 single-core, Intel leads by 4.9% (285 versus 271). In Cinebench R23 single-core, the gap widens to 35.9% (2,838 versus 1,818), a surprisingly large single-thread delta that indicates a significant clock-speed and IPC combination advantage for the Intel part in that specific test. The AMD chip does strike back in PassMark's single-thread test, scoring 3,875 versus 3,643, a 6.4% win, and that result repeats identically for the passmark_singlethread entry.

In integer-heavy workloads, Intel's lead is pronounced. PassMark integer math shows 78,330 versus 63,475, a 19% margin. Floating-point math favors Intel by an even larger 26.6% (58,037 versus 42,621). Prime number finding, a test sensitive to both core count and branch prediction, shows Intel ahead by 36.7% (98 versus 62). Physics simulation also favors Intel by 26.2% (1,475 versus 1,089).

Data compression and encryption workloads show moderate Intel advantages. PassMark data compression records 278,538 for Intel versus 237,484 for AMD, a 14.7% lead. Data encryption shows a 24.1% gap (15,574 versus 11,814). Random string sorting, a memory-latency-sensitive test, favors Intel by 14% (29,565 versus 25,435). The closest contest is extended instructions, where Intel leads by just 1.2% (17,207 versus 17,003), effectively a tie in that SIMD-heavy workload.

PassMark multithread scoring puts Intel ahead by 15.8% (23,680 versus 19,927). Overall average benchmark scores reflect the aggregate: Intel's average is 32,040 versus AMD's 29,461. The AMD chip sits at the 81st percentile of all CPUs, while Intel occupies the 82nd percentile, a marginal difference in overall rank despite the per-test deltas.

The Verdict

The data indicates a clear performance hierarchy. The Intel Core i5-14450HX is the stronger processor in almost every measured category, with particularly large advantages in multi-core rendering, physics simulation, and integer math. The AMD Ryzen AI 7 345 holds a single meaningful win in PassMark single-thread performance, but that 6.4% margin does not compensate for the 35.9% deficit in Cinebench R23 single-core or the 43% deficit in Cinebench R23 multi-core.

For users prioritizing multi-threaded workloads such as video rendering, 3D simulation, or data compression, the Intel part is the clear choice based on these measurements. The AMD chip's appeal would rest on its 28 Watt TDP versus Intel's 55 Watt TDP, its 4 nm process node versus Intel's 10 nm node, and its integrated Radeon 840M graphics versus Intel's UHD Graphics 710, but the benchmark scores do not show a performance advantage in the tested workloads. The database places the Intel processor at the 82nd percentile and the AMD processor at the 81st, a narrow overall gap that masks the wide per-test deltas.

Specification Differences

The two processors differ in several core specifications. The Intel Core i5-14450HX uses 10 cores and 16 threads, while the AMD Ryzen AI 7 345 uses 6 cores and 12 threads. Base clocks are 2.40 GHz for Intel and 2.00 GHz for AMD, with boost clocks of 4.80 GHz and 4.60 GHz respectively. Thermal design power is 55 Watts for Intel and 28 Watts for AMD.

Sockets differ: Intel uses BGA 1964, AMD uses Socket FP8. The Intel part supports DDR4 and DDR5 memory, while AMD supports DDR5 and LPDDR5X. Memory bandwidth is recorded only for AMD at 89.6 GB/s. ECC memory support is present on the Intel part and absent on the AMD part. PCIe connectivity differs: Intel provides Gen 5 with 16 lanes (CPU only), AMD provides Gen 4 with 14 lanes (CPU only). The Intel processor has an unlocked multiplier, the AMD part does not. Release dates differ: Intel launched on 2024-01-07, AMD on 2025-01-14. The Intel part has a recorded die size of 257 mm², while the AMD part has no listed die size.

Architecture Differences

The AMD Ryzen AI 7 345 is built on a 4 nm process at TSMC, codenamed Krackan Point, from the Ryzen AI 300 generation using Zen 5 and Zen 5c cores. The Intel Core i5-14450HX is built on a 10 nm process at Intel, codenamed Raptor Lake-HX, from the Core 14th Gen series using the Raptor Lake architecture and described as a Raptor Lake-HX Refresh.

Cache structures differ significantly. Both processors have 80 KB of L1 cache per core and 1 MB of L2 cache per core for AMD versus 2 MB per core for Intel. The L3 cache totals 4 MB for AMD and 20 MB shared for Intel. This 16 MB difference in last-level cache likely contributes to the Intel chip's advantage in memory-latency-sensitive workloads like random string sorting.

Integrated graphics differ: AMD uses the Radeon 840M, Intel uses UHD Graphics 710. The process node difference (4 nm versus 10 nm) explains the AMD chip's lower 28 Watt TDP despite lower core counts. The AMD processor uses a hybrid Zen 5 / Zen 5c core arrangement, while Intel's Raptor Lake-HX refresh uses its established performance and efficiency core design, though the database does not list individual core type counts for the Intel part. The AMD chip's architecture is newer, but the benchmark data shows the older Intel design delivers higher measured performance across nearly all recorded tests.
