AMD Ryzen AI 7 345 vs Intel Core 5 320 Comparison

Where Each One Wins

The benchmark data splits these two mobile processors into clear usage domains. The AMD Ryzen AI 7 345 takes 9 of the 15 recorded head-to-head wins, and those victories concentrate in multi-threaded and data-heavy workloads. The Intel Core 5 320 wins 6 tests, and its advantages appear in single-threaded tasks and specific computational patterns.

For productivity workloads that scale with core count and thread count, the AMD part is the decisive pick. In Cinebench R23 multi-core, the Ryzen AI 7 345 scores 11461 against 6197 for the Intel Core 5 320, a 84.9% lead. The Cinebench R15 multi-core test shows a similar pattern, with AMD ahead by 62.4% (1712 versus 1054). This gap reflects the AMD processor's 12 threads versus 6 on the Intel side, a structural advantage that shows up in any heavily parallelized render or compilation task.

Integer math is another AMD stronghold. The PassMark integer math score of 63475 versus 32323 represents a 96.4% advantage, the largest single delta in the entire comparison. Data compression follows at 59.6% ahead (237484 versus 148779), and random string sorting goes to AMD by 41% (25435 versus 18038). Extended instruction workloads also favor AMD, with a 28.2% margin (17003 versus 13262).

The Intel Core 5 320 wins the single-threaded contests. PassMark single-thread score is 4045 versus 3875, a 4.2% edge. Cinebench R23 single-core shows Intel ahead by 5.6% (1926 versus 1818), and Cinebench R15 single-core is a narrow 1.8% Intel victory (276 versus 271). The most striking Intel win, however, is in prime number finding, where it scores 110 against 62, a 43.6% advantage. This pattern suggests Intel's architecture handles certain deterministic, low-thread-count operations more efficiently.

The physics test also goes to Intel, 1221 versus 1089, a 10.8% margin. Floating point math is essentially a tie, with AMD at 42621 and Intel at 42440, a 0.4% difference that falls within measurement noise. Data encryption is a modest AMD win at 7.6% (11814 versus 10984), and the multithread PassMark composite favors AMD by 29% (19927 versus 15450).

For users prioritizing multi-core rendering, compression, or encryption, the AMD Ryzen AI 7 345 is the stronger choice. For single-threaded responsiveness and specific computational patterns like prime number generation, the Intel Core 5 320 holds an advantage.

Architecture Differences

The two processors come from different foundries and process nodes. The AMD Ryzen AI 7 345 uses TSMC's 4 nm process, while the Intel Core 5 320 is built on Intel's 3 nm node. Both are mobile parts, but they belong to different generations: the AMD chip is from the Ryzen AI 300 series based on the Krackan Point codename, mixing Zen 5 and Zen 5c cores. The Intel part is from the Core 5 generation with the Wildcat Lake codename.

Core counts match at 6 physical cores each, but the thread counts diverge sharply. The AMD processor supports 12 threads through simultaneous multithreading, while the Intel Core 5 320 has 6 threads, meaning no hyper-threading. This explains the large multi-core deltas.

Cache configurations differ significantly. The AMD part has 80 KB of L1 per core, 1 MB of L2 per core, and 4 MB of L3 cache. The Intel chip lists 192 KB of L1 total, 2.5 MB of L2, and 6 MB of shared L3. The Intel processor actually has more total L3 cache, but the AMD chip's larger per-core L2 allocation helps feed its 12 threads.

Clock speeds show a shared boost ceiling of 4.60 GHz for both processors. The base clocks differ, with AMD at 2.00 GHz and Intel at 1.50 GHz. The AMD part has a 28 W TDP, while the Intel part is rated at 15 W, indicating a higher power envelope for the AMD chip.

Memory architecture is another clear split. The AMD Ryzen AI 7 345 supports dual-channel memory with a bandwidth of 89.6 GB/s. The Intel Core 5 320 uses single-channel memory, delivering 59.7 GB/s. Both accept DDR5 and LPDDR5X, and neither supports ECC. PCIe lanes also differ: AMD provides Gen 4 with 14 CPU lanes, Intel provides Gen 4 with 6 CPU lanes.

Integrated graphics differ by vendor and configuration. The AMD chip uses the Radeon 840M, while the Intel part uses Intel Xe3 Graphics with 2 Xe cores. Sockets are incompatible: AMD Socket FP8 versus Intel BGA 1516. Neither processor has an unlocked multiplier.
