AMD Ryzen AI 7 345 vs Intel Core i7-12650H Comparison

Head-to-Head Benchmarks

The recorded data shows a clear split between these two mobile processors. The Intel Core i7-12650H wins the majority of the head-to-head matchups, taking 10 of the 15 recorded benchmarks, while the AMD Ryzen AI 7 345 secures 5 wins. However, the AMD chip’s victories are concentrated in single-threaded performance and extended instruction workloads, making this a nuanced comparison rather than a total sweep.

The Intel part’s most decisive victory comes in the PassMark find prime numbers test, where it scores 91 against AMD’s 62, a 31.9% advantage. This is a substantial margin that highlights a significant gap in integer-heavy, latency-sensitive workloads. The Intel chip also dominates in floating-point math, scoring 54934 versus AMD’s 42621, a 22.4% lead. In physics simulation, Intel extends its advantage to 23.8%, scoring 1430 against AMD’s 1089. These three benchmarks alone paint a picture of a processor that excels at sustained, compute-heavy tasks.

The Intel chip also leads in multi-threaded workloads across both Cinebench versions. In Cinebench R15 multicore, Intel scores 1851.5 against AMD’s 1712, a 7.5% advantage. In Cinebench R23 multicore, the gap narrows to 5.1%, with Intel at 12074 and AMD at 11461. This pattern is consistent in PassMark multithread, where Intel scores 21962 versus AMD’s 19927, a 9.3% lead. The data suggests that Intel’s higher core count translates into measurable, though not overwhelming, multi-core superiority.

Data compression and encryption also favor Intel. In PassMark data compression, Intel scores 250026 against AMD’s 237484, a 5% edge. In data encryption, Intel’s lead grows to 15.9%, scoring 14041 versus AMD’s 11814. Integer math follows suit, with Intel at 73641 against AMD’s 63475, a 13.8% advantage. Random string sorting is closer, with Intel leading by 4.3% (26591 versus 25435).

The AMD Ryzen AI 7 345’s wins are just as telling. In PassMark single-thread, AMD scores 3875 against Intel’s 3539, a 9.5% lead. This is mirrored in Cinebench R15 single-core, where AMD wins by 8.4% (271 versus 250), and in Cinebench R23 single-core, where AMD leads by 3.1% (1818 versus 1763). The AMD chip also wins the extended instructions test, scoring 17003 against Intel’s 15438, a 10.1% advantage. These results indicate that AMD’s architecture delivers superior per-thread performance, which is critical for lightly-threaded applications and responsiveness.

When looking at the broader database context, the AMD Ryzen AI 7 345 sits at the 81st percentile of all CPUs, while the Intel Core i7-12650H sits at the 80th percentile. The AMD chip’s average benchmark score is 29461, while Intel’s is 28815. The nearest rivals for AMD include the AMD Ryzen 7 3800X with a delta of 0%, and the AMD EPYC 9654 with a 0.2% delta, showing that the Ryzen AI 7 345 is competitive with much higher-tier desktop parts. Intel’s nearest rivals include the Intel Core i5-12600H with a -0.2% delta, indicating the i7-12650H is essentially on par with its own sibling in average score. This data confirms that while Intel wins more individual tests, the overall performance profile of the AMD chip is more consistent and places it slightly higher in the aggregate ranking.

Architecture Differences

The two processors are built on fundamentally different architectures and process nodes. The AMD Ryzen AI 7 345 is manufactured on a 4 nm process at TSMC, while the Intel Core i7-12650H uses a 10 nm process at Intel’s own foundry. This process advantage is part of why AMD achieves higher single-thread scores despite having fewer cores.

The core configurations differ significantly. The AMD chip features 6 cores and 12 threads, using the Krackan Point codename with a Ryzen AI 300 generation designation based on a hybrid Zen 5 / Zen 5c design. The Intel chip features 10 cores and 16 threads, using the Alder Lake-H architecture with a Core 12th Gen series designation. Intel’s die size is listed at 217 mm², while AMD’s die size is not recorded in the database.

Cache hierarchies also diverge. Both processors have an L1 cache of 80 KB per core and an L2 cache of 1 MB per core for AMD versus 1.25 MB per core for Intel. The L3 cache is a major differentiator: AMD has only 4 MB of L3 cache, while Intel has 24 MB of shared L3 cache. This six-fold difference in last-level cache likely contributes to Intel’s strong performance in multi-threaded and data-heavy workloads, where larger caches reduce memory stalls.

Memory support also differs. The AMD chip supports DDR5 and LPDDR5X memory with a dual-channel bus and a recorded memory bandwidth of 89.6 GB/s. The Intel chip supports DDR4 and DDR5 memory with a dual-channel bus, but its memory bandwidth is not recorded in the database. This means AMD offers a specific bandwidth figure while Intel’s remains unspecified.

PCIe lanes also separate the two. AMD provides Gen 4 with 14 lanes (CPU only), while Intel provides Gen 4 with 20 lanes (CPU only). This gives Intel more headroom for expansion devices. Integrated graphics differ as well: AMD uses the Radeon 840M, while Intel uses UHD Graphics. Both processors are unlocked in terms of multiplier, meaning neither supports overclocking. Neither supports ECC memory.

Base and boost clocks show Intel holding a slight edge on paper. Intel’s base clock is 2.30 GHz versus AMD’s 2.00 GHz, and Intel’s boost clock is 4.70 GHz versus AMD’s 4.60 GHz. Yet the benchmark data shows AMD winning single-thread tests, indicating that IPC and architectural efficiency matter more than raw clock speed in these workloads. The TDP also differs: AMD is rated at 28 W, while Intel is rated at 45 W. This suggests AMD achieves its results with lower power draw, though the database does not record any direct power consumption measurements.

The AMD chip’s release date is recorded as 2025-01-14, while Intel’s release date is null in the database. Both processors are marked as Active in production status and target the Mobile market segment.

The Verdict

The data points to two distinct use cases. The Intel Core i7-12650H is the stronger overall performer in multi-threaded and compute-heavy tasks. Its 10 cores and 16 threads, combined with 24 MB of L3 cache, deliver wins in 10 of 15 benchmarks, with particularly large margins in prime number finding, floating-point math, and physics. Any workload that scales with core count and benefits from a large cache will favor this chip.

The AMD Ryzen AI 7 345 is the better choice for single-threaded responsiveness and efficiency. Its 9.5% lead in PassMark single-thread and 8.4% lead in Cinebench R15 single-core show that it handles lightly-threaded tasks with greater speed. The extended instructions win by 10.1% also suggests that modern, instruction-rich code runs better on AMD. Its 28 W TDP, compared to Intel’s 45 W, indicates a more power-efficient design, although the database does not include direct power measurements.

For users who prioritize multi-core rendering, data encryption, or physics simulation, the Intel chip is the verdict. For users who prioritize single-thread speed, instruction throughput, and lower power draw, the AMD chip is the verdict. The aggregate benchmark scores, 29461 for AMD versus 28815 for Intel, slightly favor AMD, but the head-to-head wins favor Intel. This is a classic trade-off between raw multi-threaded throughput and per-thread efficiency.
