AMD Ryzen AI 7 345 vs Intel Core 5 220H Comparison

The Verdict

The benchmark database presents a clear split between these two mobile processors. The Intel Core 5 220H wins 10 of the 15 recorded head-to-head comparisons, while the AMD Ryzen AI 7 345 takes 5. The average benchmark scores reflect this: the AMD part sits at 29461, the Intel at 28574, a difference of about 3 percent in AMD's favor when averaging across all tests, but the raw win count tells a different story.

For users who prioritize raw multi-threaded throughput in applications like data encryption, physics simulation, and integer math, the Intel Core 5 220H is the stronger choice. Its wins in PassMark physics (1478 vs 1089, a 26.3 percent margin) and data encryption (15216 vs 11814, a 22.4 percent margin) are substantial. The Intel part also leads in Cinebench R15 multicore, scoring 1835 against AMD's 1712.

The AMD Ryzen AI 7 345 counters with a decisive advantage in single-threaded performance. Its PassMark single-thread score of 3875 beats Intel's 3405 by 13.8 percent. It also wins Cinebench R23 multicore (11461 vs 11198, a 2.3 percent margin) and extended instructions (17003 vs 14642, a 16.1 percent margin). For workloads that favor newer instruction sets and lighter, more responsive single-core tasks, the AMD chip is the pick.

The percentile rankings are nearly identical: AMD at 81st percentile versus Intel at 80th among all CPUs in the database. This suggests the two processors are close overall, with the differences being workload-specific rather than a generational gap. The Intel launch MSRP is $342, while AMD's field is not recorded, so no pricing comparison can be made from the data.

Architecture Differences

The two chips come from fundamentally different design philosophies. The AMD Ryzen AI 7 345 uses the Krackan Point codename, belonging to the Ryzen AI 300 generation built on Zen 5 and Zen 5c cores. It is manufactured on a 4 nm process by TSMC. The Intel Core 5 220H, meanwhile, is a Raptor Lake-H part, part of the Core 5 (Raptor Lake Refresh) generation, built on Intel's 10 nm process.

The core counts diverge sharply. AMD packs 6 cores and 12 threads, while Intel offers 12 cores and 16 threads. This explains Intel's advantage in heavily parallel workloads despite its older process node. The Intel chip has a higher base clock (2.70 GHz vs 2.00 GHz) and a higher boost clock (4.90 GHz vs 4.60 GHz), but the AMD part achieves better single-thread scores in several tests, suggesting its Zen 5 architecture is more efficient per clock.

Cache configurations also differ. Both have 80 KB L1 per core and 1 MB L2 per core on AMD versus 2 MB L2 per core on Intel. The L3 cache is a stark contrast: AMD provides 4 MB, while Intel offers 18 MB shared. This larger L3 cache on Intel likely contributes to its strong performance in data compression and encryption tasks, where larger working sets can reside on-chip.

Memory support shows another divergence. AMD supports DDR5 and LPDDR5X with dual-channel memory and a recorded bandwidth of 89.6 GB/s. Intel supports DDR4 and DDR5, also dual-channel, but no bandwidth figure is recorded in the database. Both lack ECC support. PCIe capabilities differ: AMD uses Gen 4 with 14 lanes (CPU only), while Intel uses Gen 5 with 8 lanes (CPU only). The integrated graphics also differ: AMD has the Radeon 840M, Intel has Iris Xe Graphics 80EU.

Where Each One Wins

The Intel Core 5 220H dominates in raw computational stress tests. Its PassMark physics score of 1478 versus AMD's 1089 (a 26.3 percent lead) suggests it handles complex physical simulations more efficiently. Data encryption is another Intel stronghold, with a 22.4 percent edge (15216 vs 11814). Prime number finding favors Intel by 24.4 percent (82 vs 62), and floating-point math by 17.5 percent (51671 vs 42621). Integer math also goes Intel's way, 73555 to 63475, a 13.7 percent margin. Random string sorting favors Intel by 10.6 percent (28438 vs 25435), and multithreaded PassMark by 8.9 percent (21884 vs 19927).

The AMD Ryzen AI 7 345 wins where single-thread efficiency and modern instruction sets matter. Its PassMark single-thread score of 3875 eclipses Intel's 3405 by 13.8 percent. Extended instructions show a 16.1 percent advantage (17003 vs 14642), indicating better support for newer SIMD and specialized instruction workloads. In Cinebench R23 multicore, AMD wins 11461 to 11198, a modest 2.3 percent edge, and in Cinebench R15 single-core, AMD leads 271 to 262, a 3.4 percent margin.

The use-case split is clear: Intel for sustained multi-core workloads like video rendering, physics engines, and encryption-heavy tasks; AMD for responsive single-threaded applications, legacy code paths that benefit from higher per-core performance, and workloads that leverage extended instruction sets.

Head-to-Head Benchmarks

The largest Intel victories are in physics and encryption. In PassMark physics, Intel scores 1478 against AMD's 1089, a 26.3 percent delta. This is the single biggest gap in the entire comparison. Data encryption follows with Intel at 15216 and AMD at 11814, a 22.4 percent margin. Prime number finding shows an 82 to 62 result, a 24.4 percent lead for Intel. Floating-point math favors Intel 51671 to 42621, a 17.5 percent margin. These results suggest Intel's higher core count and larger cache provide a substantial advantage in mathematically intensive parallel workloads.

The AMD victories are concentrated in single-thread and instruction-set tests. PassMark single-thread shows 3875 for AMD versus 3405 for Intel, a 13.8 percent margin. Extended instructions favor AMD 17003 to 14642, a 16.1 percent lead. Cinebench R15 single-core goes to AMD 271 to 262 (3.4 percent). Cinebench R23 multicore is closer, with AMD winning 11461 to 11198 (2.3 percent). These wins indicate that AMD's Zen 5 architecture extracts more performance per clock in less parallelized tasks.

The Cinebench results are particularly interesting. Intel wins R15 multicore (1835 vs 1712, a 6.7 percent margin), but AMD wins R23 multicore (11461 vs 11198, a 2.3 percent margin). This reversal suggests the two processors scale differently under varying workload intensities. The R15 test may favor Intel's higher clock speeds, while R23's longer duration may allow AMD's efficiency to shine. The R23 single-core result goes Intel's way (1853 vs 1818, a 1.9 percent margin), while R15 single-core goes AMD's way (271 vs 262, a 3.4 percent margin). These cross-results highlight that benchmark selection materially affects the perceived winner.
