AMD Ryzen AI 7 345 vs Intel Core i7-14650HX Comparison

The Verdict

The benchmark data delivers a decisive outcome: the Intel Core i7-14650HX wins 13 of the 15 head-to-head comparisons, while the AMD Ryzen AI 7 345 takes only 2. The Intel part leads by substantial margins in nearly every multi-threaded and compute-intensive test, often by 40% to 50% or more. The AMD chip's only victories are narrow single-thread wins in PassMark, where it edges ahead by 0.9%.

The Core i7-14650HX is the clear choice for workloads that scale across cores: rendering, compilation, encryption, data compression, and floating-point math. Its Cinebench R23 multi-core score of 20454 versus 11461 for the Ryzen AI 7 345 represents a 44% advantage, and the PassMark multi-thread score of 33495 versus 19927 is a 40.5% gap. The Intel part also holds a 50.7% lead in Cinebench R15 multi-core and a 49.9% lead in PassMark floating-point math.

The AMD Ryzen AI 7 345, however, is not without merit. Its PassMark single-thread score of 3875 tops the Intel's 3841, a marginal but real edge in lightly threaded responsiveness. The AMD chip also operates at a much lower 28W TDP compared to Intel's 55W, which suggests it fits into thinner, lighter chassis with less demanding cooling. The data shows that buyers prioritizing battery life and portability over raw throughput should consider the AMD part, while those needing maximum compute performance should select the Intel.

The overall average benchmark score tells the same story: the Intel Core i7-14650HX sits at 41576, placing it in the 88th percentile of all CPUs, while the AMD Ryzen AI 7 345 scores 29461, in the 81st percentile. The Intel processor's nearest rivals include the AMD Ryzen 9 5900X with a 0.5% delta, while the AMD chip's nearest rivals include the Intel Core i5-13500HX with a 0.7% delta, which places the two in different performance strata.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI 7 345 uses the Krackan Point codename, part of the Ryzen AI 300 generation built on Zen 5 and Zen 5c cores. It is fabricated on a 4 nm process at TSMC. The Intel Core i7-14650HX belongs to the Core 14th Gen series, using the Raptor Lake architecture with the Raptor Lake-HX codename, and is built on a 10 nm process at Intel with a die size of 257 mm².

Core counts differ dramatically. The AMD chip provides 6 cores and 12 threads, while the Intel part offers 16 cores and 24 threads. That 10-core and 12-thread gap directly explains the large multi-threaded benchmark deltas. The Intel processor also has a higher base clock of 2.20 GHz and boost clock of 5.20 GHz, compared to AMD's 2.00 GHz base and 4.60 GHz boost.

Cache hierarchies also diverge. Both use 80 KB of L1 cache per core and 1 MB of L2 per core, but the Intel chip doubles the L2 to 2 MB per core and provides 30 MB of shared L3 cache. The AMD chip has only 4 MB of L3 cache. This difference in shared cache capacity can affect workloads with large working sets.

Memory support varies as well. The AMD chip supports DDR5 and LPDDR5X with dual-channel memory and a bandwidth of 89.6 GB/s. The Intel chip supports DDR4 and DDR5 with dual-channel memory but has no listed bandwidth figure. The Intel part also supports ECC memory, while the AMD chip does not. PCIe connectivity differs: AMD uses Gen 4 with 14 CPU lanes, while Intel uses Gen 5 with 16 CPU lanes.

Integrated graphics also differ. The AMD Ryzen AI 7 345 includes a Radeon 840M, while the Intel Core i7-14650HX uses UHD Graphics 710. The sockets are incompatible: AMD uses Socket FP8, and Intel uses BGA 1964. The AMD chip's multiplier is locked, while the Intel part's multiplier is unlocked, allowing overclocking on supported platforms.

Head-to-Head Benchmarks

The Intel Core i7-14650HX dominates every multi-threaded Cinebench test. In Cinebench R15 multi-core, Intel scores 3470.5 versus AMD's 1712, a 50.7% lead. In Cinebench R23 multi-core, Intel scores 20454 versus 11461, a 44% lead. The single-core Cinebench results are closer but still favor Intel: R15 single-core shows 285.5 versus 271 (5.1% lead), and R23 single-core shows 1969 versus 1818 (7.7% lead).

PassMark tests show a consistent pattern of Intel dominance. Data compression: Intel 398418 versus AMD 237484, a 40.4% lead. Data encryption: Intel 22917 versus AMD 11814, a 48.4% lead. Extended instructions: Intel 24150 versus AMD 17003, a 29.6% lead. Find prime numbers: Intel 152 versus AMD 62, a 59.2% lead, the largest gap in any test. Floating-point math: Intel 84999 versus AMD 42621, a 49.9% lead. Integer math: Intel 116661 versus AMD 63475, a 45.6% lead. Multi-thread: Intel 33495 versus AMD 19927, a 40.5% lead. Physics: Intel 2202 versus AMD 1089, a 50.5% lead. Random string sorting: Intel 43035 versus AMD 25435, a 40.9% lead.

The only AMD wins are in PassMark single-thread tests, where AMD scores 3875 against Intel's 3841, a 0.9% advantage. This appears twice in the database, once as "passmark_single_thread" and once as "passmark_singlethread", confirming consistency.

Where Each One Wins

The Intel Core i7-14650HX wins in every multi-core, parallel, and compute-heavy category. Its 16 cores and 24 threads provide a 44-50.7% advantage in Cinebench multi-core tests, and its 40-59.2% leads across PassMark workloads cover data compression, encryption, extended instructions, prime number finding, floating-point math, integer math, multi-thread performance, physics, and random string sorting. This makes it the appropriate choice for video rendering, 3D modeling, software compilation, scientific computing, and any workload that saturates all available cores. The Intel chip also wins all single-core Cinebench tests, with 5.1% and 7.7% leads in R15 and R23 respectively.

The AMD Ryzen AI 7 345 wins only in PassMark single-thread scoring, with a 0.9% edge. This is a narrow margin and unlikely to translate into perceptible real-world differences for most users. However, the AMD chip operates at a 28W TDP, less than half of the Intel's 55W, which means it can be deployed in thinner, lighter laptops with smaller batteries and quieter cooling solutions. The AMD chip's 4 nm process and 89.6 GB/s memory bandwidth also indicate a more power-efficient design. For users who prioritize portability, battery life, and lower thermal output over maximum compute throughput, the AMD Ryzen AI 7 345 is the data-backed choice. For everyone else, the Intel Core i7-14650HX is the performance leader by a wide margin.
