AMD Ryzen AI 7 345 vs Intel Core 3 100U Comparison

Head-to-Head Benchmarks

The benchmark database records a comprehensive sweep for the AMD Ryzen AI 7 345. Across all 15 head-to-head comparisons, the AMD processor finishes ahead of the Intel Core 3 100U. The margins, however, vary considerably by workload type, which reveals the specific strengths of each design.

The largest single advantage appears in PassMark's extended instructions test. The AMD Ryzen AI 7 345 scores 17,003 against 7,894 for the Intel Core 3 100U, a delta of 115.4%. This category typically exercises advanced SIMD and cryptography-related instruction paths, and the data confirms a massive throughput advantage for the AMD part.

Cinebench R15 multi-core shows a 60% lead, with the AMD chip scoring 1,712 versus 1,070. The single-core R15 result is even more lopsided: 271 versus 150, a difference of 80.7%. These large deltas in the older Cinebench version suggest the AMD part sustains high clocks more effectively under this specific workload. In Cinebench R23, the gap narrows substantially. The multi-core scores are 11,461 and 10,624, a 7.9% margin, while single-core shows 1,818 against 1,499, a 21.3% advantage. The R23 multi-core result is the closest contest in the entire dataset, indicating that the Intel chip scales relatively better in this longer, more demanding render loop.

PassMark integer math favors AMD by 60.4%, with scores of 63,475 and 39,580. Floating-point math shows a 50.5% lead, 42,621 versus 28,322. Data compression delivers a 74% margin, 237,484 against 136,497. Data encryption is 45.3% ahead for AMD, 11,814 versus 8,128. Random string sorting shows a 67.4% lead, 25,435 versus 15,191. Prime number finding is closer, at 19.2%, with scores of 62 and 52. The PassMark multi-thread score gives AMD a 59.1% advantage, 19,927 versus 12,522, while the physics test shows a 24.3% edge, 1,089 versus 876.

The smallest overall margin in the entire comparison is PassMark single-thread performance. The AMD Ryzen AI 7 345 scores 3,875, and the Intel Core 3 100U scores 3,506, a 10.5% difference. This indicates that for purely single-threaded desktop responsiveness, the two processors are much closer than the multi-thread results suggest. Still, the AMD part wins every recorded benchmark, making the head-to-head outcome unambiguous.

The Verdict

The recorded data points to a clear overall winner: the AMD Ryzen AI 7 345. Its average benchmark score of 29,461 places it in the 81st percentile of all CPUs in the database. The Intel Core 3 100U averages 16,148, sitting in the 70th percentile. That average score difference is roughly 82%, which is consistent with the wide margins seen across most individual tests.

The AMD processor's nearest rivals in the database include the AMD Ryzen 7 3800X at 29,447 (a 0% delta), the AMD EPYC 9654 at 29,409 (0.2% behind), and the Intel Core i5-13500HX at 29,270 (0.7% behind). This places the Ryzen AI 7 345 in the company of high-end desktop and workstation parts, despite being a 28 W mobile chip. The Intel Core 3 100U, by contrast, sits alongside the Intel Core i7-10850H at 16,204 (0.3% ahead of it), the Intel Core i5-10600KF at 16,228 (0.5% ahead), and the Intel Core i7-1260U at 16,320 (1.1% ahead). The Core 3 100U's nearest rivals are older laptop and desktop processors from several generations back.

For users whose priority is raw compute throughput, the data supports choosing the AMD Ryzen AI 7 345. It wins every single head-to-head test, and in several categories the margin exceeds 50%. The Intel Core 3 100U does not win a single benchmark in this comparison. The only area where the Intel part is remotely competitive is single-thread PassMark, where the 10.5% gap is the smallest recorded. That single result does not offset the multi-thread dominance of the AMD part. The verdict from the database is straightforward: the AMD Ryzen AI 7 345 is the higher-performing processor across the measured workload spectrum.

Where Each One Wins

The AMD Ryzen AI 7 345 wins in every category recorded, so the more useful analysis is where its advantage is largest and where the Intel Core 3 100U comes closest.

The AMD chip's biggest victories are in extended instructions (115.4% ahead), Cinebench R15 single-core (80.7%), data compression (74%), random string sorting (67.4%), integer math (60.4%), Cinebench R15 multi-core (60%), and PassMark multi-thread (59.1%). These results indicate that the AMD processor is particularly strong in compute-heavy, parallel, and data-manipulation workloads. The PassMark multi-thread score of 19,927 against 12,522 suggests the Ryzen AI 7 345 can handle heavily threaded productivity applications with substantially more headroom.

The Intel Core 3 100U comes closest in PassMark single-thread (10.5% behind), Cinebench R23 multi-core (7.9% behind), and prime number finding (19.2% behind). The R23 multi-core result is notable because the Intel chip has only 8 threads against 12 for the AMD part, yet it closes the gap to under 8%. This suggests that the Intel architecture handles the R23 render loop more efficiently per thread. The single-thread PassMark result also shows that for everyday light tasks, the Intel chip is not far off.

In practice, the AMD Ryzen AI 7 345 is the better choice for content creation, software compilation, data analysis, and any workload that scales across threads. The Intel Core 3 100U, given its competitive single-thread and R23 multi-core scores, can handle general productivity and light rendering tasks without severe penalty, but the database does not show a single workload where it outperforms the AMD part.

Architecture Differences

The two processors use fundamentally different designs. The AMD Ryzen AI 7 345 is built on the Krackan Point codename, part of the Ryzen AI 300 generation that combines Zen 5 and Zen 5c cores. It is manufactured on a 4 nm process at TSMC. The Intel Core 3 100U uses the Raptor Lake architecture, specifically Raptor Lake-U, and is fabricated on Intel's 10 nm process.

Both chips have 6 cores, but the AMD part supports 12 threads through simultaneous multithreading, while the Intel part supports 8 threads. The AMD base clock is 2.00 GHz with a boost clock of 4.60 GHz. The Intel base clock is 1.20 GHz with a boost clock of 4.70 GHz. The higher Intel boost clock does not translate into benchmark wins, as the recorded data shows the AMD part ahead in every test.

The cache configurations differ notably. The AMD Ryzen AI 7 345 has 80 KB of L1 per core, 1 MB of L2 per core, and 4 MB of L3 cache. The Intel Core 3 100U also has 80 KB of L1 per core, but 1.25 MB of L2 per core and a larger 10 MB shared L3 cache. The larger Intel L3 cache does not overcome the AMD advantage in the recorded workloads.

Memory support also diverges. The AMD chip supports DDR5 and LPDDR5X memory over a dual-channel bus, with a recorded memory bandwidth of 89.6 GB/s. The Intel chip supports DDR4 and DDR5 over a dual-channel bus, with no bandwidth figure recorded in the database. Neither processor supports ECC memory. The AMD part provides PCIe Gen 4 with 14 CPU lanes, while the Intel part provides PCIe Gen 4 with 8 CPU lanes.

The integrated graphics differ as well. The AMD Ryzen AI 7 345 uses the Radeon 840M, while the Intel Core 3 100U uses UHD Graphics 64EU. The AMD chip has a TDP of 28 W, while the Intel chip has a TDP of 15 W, reflecting the Intel part's lower power envelope. The AMD processor uses the AMD Socket FP8, and the Intel processor uses Intel BGA 1744. The AMD part was released in January 2025, and the Intel part was released in January 2024. The Intel Core 3 100U carries a launch MSRP of $426. The AMD part's launch MSRP is not recorded. Neither processor has an unlocked multiplier.
