AMD Ryzen 7 PRO 5755G vs AMD Ryzen AI 7 345 Comparison

The AMD Ryzen 7 PRO 5755G and AMD Ryzen AI 7 345 represent two distinct design philosophies from AMD: a desktop-focused, high-core-count processor versus a mobile-focused, efficiency-oriented chip. The recorded benchmark data shows a clear split between raw multi-threaded throughput and single-thread efficiency. The Ryzen 7 PRO 5755G wins 7 of the 11 head-to-head comparisons, while the Ryzen AI 7 345 takes the remaining 4.

Head-to-Head Benchmarks

The most decisive victory for the Ryzen 7 PRO 5755G comes in the PassMark integer math test, where it scores 90,270 against the Ryzen AI 7 345's 63,475, a 42.2% advantage. This substantial lead indicates that the desktop processor's eight full Zen 3 cores handle integer workloads with far greater aggregate throughput. Data encryption shows an even larger relative gap in percentage terms: the 5755G scores 19,450 versus 11,814, a 64.6% difference. That is the single biggest proportional win for the desktop part in the entire comparison.

The 5755G also delivers a 24.5% lead in data compression, scoring 295,730 against 237,484. Random string sorting favors the desktop chip by 28.8%, with scores of 32,771 and 25,435. Floating-point math goes to the 5755G at 50,778 versus 42,621, a 19.1% margin. Extended instructions follow the same pattern: 20,487 for the 5755G and 17,003 for the Ryzen AI 7 345, a 20.5% difference. The overall multithread score confirms the pattern, with the 5755G at 23,858 and the Ryzen AI 7 345 at 19,927, a 19.7% lead.

The Ryzen AI 7 345 counters in several key tests. Its single-thread score of 3,875 is 13.1% higher than the 5755G's 3,366. This is a significant margin for single-threaded performance and reflects the newer architecture's advantages in per-core efficiency. The mobile processor also wins the find prime numbers test, scoring 62 versus 58, a 6.5% edge. In the physics test, the Ryzen AI 7 345 scores 1,089 against 1,022, a 6.2% win.

The average benchmark scores place the two processors far apart. The 5755G has an average benchmark score of 49,196, while the Ryzen AI 7 345 sits at 29,461. This overall average heavily weights the desktop part's multi-threaded dominance. In terms of overall CPU percentile ranking, the 5755G places in the 90th percentile of all CPUs, while the Ryzen AI 7 345 ranks in the 81st percentile. The nearest rivals for each chip in the database confirm their relative positioning: the 5755G trades blows with the AMD Ryzen 9 7900 (0.1% behind) and the Intel Core i5-14600KF (0.4% behind), while the Ryzen AI 7 345 matches the AMD Ryzen 7 3800X exactly (0.0% delta) and sits just 0.7% ahead of the Intel Core i5-13500HX.

Where Each One Wins

From the benchmark data, the Ryzen 7 PRO 5755G is the clear choice for workloads that scale with core count and thread count. Its eight cores and sixteen threads provide substantial parallelism for data compression, encryption, sorting, and math-heavy tasks. The 42.2% lead in integer math and the 64.6% lead in encryption specifically indicate that the desktop chip handles compute-intensive, parallelizable operations with much greater total throughput.

The Ryzen AI 7 345 wins where single-thread performance and per-core efficiency matter most. Its 13.1% advantage in single-thread score suggests that applications with light threading, such as legacy software or latency-sensitive single-core tasks, will run faster on the mobile chip. The wins in find prime numbers and physics, both by roughly 6%, reinforce this pattern. Those tests often respond well to higher per-core IPC and clock behavior rather than raw core count.

The multithread score difference of 19.7% in favor of the 5755G shows that the desktop part's extra two cores and four threads outweigh the mobile chip's architectural advantages in heavily parallel scenarios. For a user running long multi-threaded renders or batch processing, the 5755G's higher throughput is the deciding factor. For interactive or lightly threaded workloads, the Ryzen AI 7 345's higher single-thread score provides the better experience.

Architecture Differences

The two processors come from different generations and process nodes. The Ryzen 7 PRO 5755G uses Zen 3 architecture on a 7 nm TSMC process, with the Cezanne codename. The Ryzen AI 7 345 uses a hybrid Zen 5 / Zen 5c configuration on a 4 nm TSMC process, with the Krackan Point codename. The process node difference is significant: 7 nm versus 4 nm directly contributes to the mobile chip's lower power envelope and higher per-core efficiency.

Core configurations differ markedly. The 5755G has 8 cores and 16 threads, while the Ryzen AI 7 345 has 6 cores and 12 threads. The desktop chip's higher core count gives it the multi-threaded advantage seen throughout the benchmark data. Cache layouts also diverge. The 5755G provides 64 KB of L1 cache per core, 512 KB of L2 per core, and a 16 MB L3 cache. The Ryzen AI 7 345 provides 80 KB of L1 per core, 1 MB of L2 per core, but only 4 MB of L3 cache. The mobile chip's larger per-core L1 and L2 caches help explain its single-thread advantage, while the desktop chip's much larger L3 pool aids in data-heavy multithreaded workloads.

The memory subsystem differs completely. The 5755G supports DDR4 memory with dual-channel operation and a memory bandwidth of 51.2 GB/s. The Ryzen AI 7 345 supports DDR5 and LPDDR5X, also dual-channel, but with a much higher memory bandwidth of 89.6 GB/s. This 38.4 GB/s difference in theoretical bandwidth gives the mobile chip a substantial advantage in memory-bound operations. PCIe connectivity also differs: the 5755G uses Gen 3 with 16 CPU lanes, while the Ryzen AI 7 345 uses Gen 4 with 14 CPU lanes. The newer Gen 4 standard offers higher per-lane bandwidth.

The integrated graphics differ as well. The 5755G includes Radeon Vega 8, while the Ryzen AI 7 345 includes Radeon 840M. The power envelopes are markedly different: the 5755G has a TDP of 65 watts, while the Ryzen AI 7 345 has a TDP of 28 watts. The socket types reflect their market segments: the 5755G uses AMD Socket AM4 for desktop, while the Ryzen AI 7 345 uses AMD Socket FP8 for mobile.

The Verdict

The recorded data shows two processors built for different roles. The AMD Ryzen 7 PRO 5755G delivers significantly higher multi-threaded throughput across nearly all PassMark workloads, with wins in data compression, encryption, extended instructions, floating-point math, integer math, multithread, and random string sorting. Its 8-core, 16-thread configuration and 16 MB L3 cache make it the stronger choice for parallel workloads, and its 90th percentile ranking among all CPUs confirms its standing.

The AMD Ryzen AI 7 345 counters with a 13.1% single-thread advantage and wins in the find prime numbers and physics tests. Its 4 nm process, larger per-core L1 and L2 caches, and higher memory bandwidth of 89.6 GB/s support its per-core efficiency. The mobile chip's 28 W TDP, versus 65 W for the desktop part, also positions it for power-sensitive applications.

For desktop users running multi-threaded productivity, data processing, or compute-heavy tasks, the Ryzen 7 PRO 5755G is the stronger performer based on the benchmark results. For mobile users or those prioritizing single-thread performance and lower power consumption, the Ryzen AI 7 345 delivers better per-core results. The 81st percentile ranking for the mobile chip still places it well above average, but the data is clear: the desktop part wins the majority of head-to-head comparisons and offers a much higher average benchmark score.
