AMD Ryzen AI 7 345 vs Intel Core i5-13500HX Comparison

The AMD Ryzen AI 7 345 and Intel Core i5-13500HX are both mobile processors aimed at different performance profiles, and the benchmark data reveals a stark divide between single-threaded efficiency and raw multi-threaded throughput. The AMD part, built on a modern 4 nm process with a 28 W TDP, consistently wins the single-core tests, while the Intel part, a 55 W Raptor Lake-HX chip with more cores, dominates heavily in multi-threaded workloads. In the head-to-head suite of 15 benchmarks, the Intel Core i5-13500HX claims 11 wins, while the AMD Ryzen AI 7 345 takes 4.

Head-to-Head Benchmarks

The most lopsided victories for the Intel Core i5-13500HX come in the Cinebench multi-core tests, where its core-count advantage is decisive. In Cinebench R23 multi-core, the Intel chip scores 18334 against the AMD’s 11461, a margin of 37.5%. The gap is similar in Cinebench R15 multi-core, where Intel scores 2863 versus AMD’s 1712, a 40.2% difference. This pattern extends across PassMark’s compute-oriented workloads: in floating point math, Intel leads with 70885 to 42621 (39.9% ahead); in integer math, Intel scores 96195 versus 63475 (34% ahead); and in data encryption, Intel’s 19267 beats AMD’s 11814 by 38.7%. The data suggests that for heavily threaded rendering, simulation, or encryption tasks, the Intel part is in a different performance class.

The AMD Ryzen AI 7 345, however, wins every single-threaded test in the comparison. In Cinebench R23 single-core, AMD scores 1818 versus Intel’s 1730.5, a 5.1% advantage. In Cinebench R15 single-core, AMD leads 271 to 252, a 7.5% edge. The PassMark single-thread test shows AMD at 3875 versus Intel’s 3582, an 8.2% advantage. These are consistent wins, indicating that the AMD architecture delivers higher per-core performance, which is critical for lightly threaded applications, everyday responsiveness, and games that rely on a few fast cores.

Outside of the headline single- and multi-core splits, the Intel chip also wins the intermediate workloads. In PassMark’s data compression, Intel scores 331896 versus AMD’s 237484, a 28.4% lead. In extended instructions (SIMD-heavy code), Intel leads 20200 to 17003, a 15.8% margin. The passmark_multithread test shows Intel at 27753 versus AMD’s 19927, a 28.2% difference, while the physics test (a proxy for gaming physics calculations) favors Intel 1634 to 1089, a 33.4% delta. Random string sorting also goes to Intel, 36373 to 25435, a 30.1% lead. The only other AMD win besides the single-core tests is the passmark_find_prime_numbers test, but that is a narrow 62 to 98 loss for AMD, meaning Intel still wins that one; AMD’s wins are exclusively the four single-threaded benchmarks.

When looking at the aggregate average benchmark score, the two chips are remarkably close. The AMD Ryzen AI 7 345 has an average score of 29461, placing it at the 81st percentile of all CPUs, while the Intel Core i5-13500HX averages 29270, also at the 81st percentile. The delta between them is a mere 0.7% in favor of AMD. This suggests that while the Intel part crushes multi-threaded tasks, the AMD part’s superior single-thread performance and efficiency balance out the overall average, making them near-peers in a holistic sense.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI 7 345 is built on a 4 nm process at TSMC and uses the Krackan Point codename, part of the Ryzen AI 300 generation that employs a hybrid of Zen 5 and Zen 5c cores. It has 6 cores and 12 threads, with a base clock of 2.00 GHz and a boost clock of 4.60 GHz. The cache hierarchy includes 80 KB of L1 per core, 1 MB of L2 per core, and a total of 4 MB of L3 cache. The AMD chip supports DDR5 and LPDDR5X memory over a dual-channel bus, with a memory bandwidth of 89.6 GB/s. It uses the AMD Socket FP8 and features a Radeon 840M integrated GPU. The PCIe implementation is Gen 4 with 14 CPU lanes.

In contrast, the Intel Core i5-13500HX is a Raptor Lake-HX part built on Intel’s 10 nm process, using the Raptor Lake architecture. It has 14 cores and 20 threads, with a base clock of 2.50 GHz and a boost clock of 4.70 GHz. The cache setup is notably larger in L3, with 24 MB shared, alongside 80 KB of L1 per core and 2 MB of L2 per core. The die size is listed at 257 mm². The Intel chip supports both DDR4 and DDR5 memory over a dual-channel bus, and it includes ECC memory support, which the AMD part lacks. It uses the Intel BGA 1964 socket and has an integrated UHD Graphics 710. The PCIe implementation is more advanced, supporting Gen 5 with 20 CPU lanes. The Intel part also has an unlocked multiplier, whereas the AMD chip does not.

The process node difference is significant: AMD’s 4 nm (TSMC) versus Intel’s 10 nm. This explains why the AMD chip achieves its single-thread wins at a much lower TDP of 28 W versus Intel’s 55 W, as the smaller node allows for higher efficiency per clock.

Specification Differences

The specification sheets reveal several key divergences beyond the core counts. The Intel Core i5-13500HX has 14 cores and 20 threads, compared to the AMD Ryzen AI 7 345’s 6 cores and 12 threads. The base clock is higher on Intel (2.50 GHz versus 2.00 GHz), and the boost clock is also slightly higher (4.70 GHz versus 4.60 GHz). The TDP is nearly double on Intel, at 55 W versus AMD’s 28 W. The sockets differ: Intel uses BGA 1964, while AMD uses Socket FP8.

The cache configuration is a major differentiator. While both have 80 KB of L1 per core, the Intel chip has 2 MB of L2 per core versus AMD’s 1 MB, and Intel has 24 MB of shared L3 versus AMD’s 4 MB of L3. The memory support differs, with Intel supporting both DDR4 and DDR5, while AMD supports DDR5 and LPDDR5X. The Intel chip includes ECC memory support, and the AMD chip does not. The integrated graphics are different: AMD uses a Radeon 840M, while Intel uses UHD Graphics 710. PCIe capability also differs, with Intel offering Gen 5 and 20 lanes versus AMD’s Gen 4 and 14 lanes. The Intel part is unlocked for overclocking and has a launch MSRP of $326; the AMD part has no listed launch MSRP.

The release dates are also distinct: the AMD Ryzen AI 7 345 was released on 2025-01-14, while the Intel Core i5-13500HX was released nearly two years earlier on 2023-01-03.

The Verdict

The data presents a clear choice based on workload priorities. The Intel Core i5-13500HX is the definitive pick for multi-threaded productivity. With a 37.5% lead in Cinebench R23 multi-core and a 40.2% lead in Cinebench R15 multi-core, it is the superior processor for rendering, video encoding, data compression (28.4% lead), and heavy encryption tasks (38.7% lead). The 14-core, 20-thread configuration, combined with 24 MB of L3 cache and a 55 W TDP, provides the raw throughput that the 6-core AMD chip cannot match. Users who run parallel workloads should select the Intel part without hesitation.

The AMD Ryzen AI 7 345, however, is the better choice for single-threaded and efficiency-focused scenarios. It wins every single-thread benchmark in the head-to-head, with margins from 5.1% to 8.2%. Its 28 W TDP suggests it will generate less heat and consume less power, making it suitable for thinner, passively cooled or battery-conscious laptops. The AMD chip’s newer 4 nm process and Zen 5 architecture deliver higher per-core performance, which is beneficial for everyday applications, office work, and legacy software that does not scale across many cores. The aggregate average benchmark score is virtually identical (29461 versus 29270), but the AMD part achieves that parity at less than half the TDP.

In summary, the Intel Core i5-13500HX is the performance king for multi-threaded tasks, while the AMD Ryzen AI 7 345 is the efficiency champion for single-threaded speed and lower power draw. The data does not support a single "best" CPU; instead, the choice hinges on whether the user prioritizes parallel compute power (Intel) or per-core responsiveness and power economy (AMD).
