AMD Ryzen AI 7 445 vs Intel Core 3 100U Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive overall victory for the AMD Ryzen AI 7 445, which wins 14 of the 15 shared benchmark comparisons. The single Intel win is narrow; the Intel Core 3 100U edges ahead in Cinebench R23 multi-core by a 0.3% margin, scoring 10624 versus 10590. That result is effectively a tie, but it is the only head-to-head test where the AMD part does not come out on top.

The largest performance gap appears in PassMark extended instructions, where the AMD Ryzen AI 7 445 scores 15826 against 7894 for the Intel Core 3 100U, a 100.5% advantage. This indicates that the AMD processor delivers more than double the throughput in workloads that use advanced instruction sets. The Cinebench R15 single-core test shows the next biggest difference, with AMD leading 254 to 150, a 69.3% margin. Cinebench R15 multi-core follows closely, with AMD at 1723 versus 1070, a 61% lead.

In memory-sensitive tasks, the AMD part is consistently far ahead. PassMark data compression shows 215812 for AMD versus 136497 for Intel, a 58.1% lead. Random string sorting favors AMD by 54.6%, with scores of 23488 and 15191. Integer math shows AMD at 58332 against 39580, a 47.4% advantage, while multi-thread performance is 44.7% higher (18115 versus 12522).

Floating-point math also strongly favors the AMD processor, with a 39% lead (39362 versus 28322). Data encryption shows AMD ahead by 29.4% (10519 versus 8128). The Cinebench R23 single-core test gives AMD a 20.5% lead (1806 versus 1499). PassMark physics shows a smaller but clear 11.4% margin (976 versus 876). Prime number finding is close, with AMD at 56 versus 52, a 7.7% lead. The narrowest win is in PassMark single-thread performance, where AMD scores 3591 against 3506, a 2.4% margin.

Where Each One Wins

The AMD Ryzen AI 7 445 wins across nearly every category in the database. Its strengths are most pronounced in multi-threaded and instruction-heavy workloads, as shown by the large leads in extended instructions, data compression, integer math, and multi-thread tests. The single-core advantage is also real, especially in Cinebench R23 single-core (20.5%) and Cinebench R15 single-core (69.3%), although the PassMark single-thread gap is modest at 2.4%. For tasks that rely on encryption, sorting, or floating-point math, the AMD part delivers substantially higher scores.

The Intel Core 3 100U has one specific niche: Cinebench R23 multi-core, where it scores 10624 versus 10590. That 0.3% difference is within noise, but it does mean the Intel processor is not wholly uncompetitive in that one rendering workload. In every other recorded test, the AMD processor is ahead, with margins ranging from 2.4% to over 100%. The Intel part also shows a lower average benchmark score of 16148, compared to 26936 for AMD, and sits at the 70th percentile versus the 79th percentile for AMD.

Architecture Differences

The two processors use fundamentally different designs. The AMD Ryzen AI 7 445 is built on Zen 5 architecture with the codename Gorgon Point, part of the Ryzen AI 400 generation that combines Zen 5 and Zen 5c cores. It uses a 4 nm process from TSMC. The Intel Core 3 100U uses Raptor Lake architecture, specifically Raptor Lake-U, on a 10 nm Intel process.

Core counts are identical at 6 cores, but thread counts differ: AMD supports 12 threads via simultaneous multithreading, while Intel supports 8 threads. Base clocks are very different, with AMD at 2.00 GHz and Intel at 1.20 GHz, although boost clocks are close at 4.60 GHz for AMD and 4.70 GHz for Intel. The thermal design power also differs, with AMD rated at 28 W and Intel at 15 W.

Cache hierarchies are notably different. Both have 80 KB of L1 per core. AMD uses 1 MB of L2 per core, while Intel uses 1.25 MB per core. The L3 cache is a major differentiator: AMD has 4 MB total, while Intel has 10 MB shared. Memory support also differs: AMD supports DDR5 and LPDDR5X with dual-channel memory and a recorded bandwidth of 89.6 GB/s, while Intel supports DDR4 and DDR5 with dual-channel memory but no recorded bandwidth figure. AMD supports ECC memory; Intel does not.

PCIe connectivity differs as well. AMD provides Gen 4 with 14 lanes (CPU only), while Intel provides Gen 4 with 8 lanes (CPU only). Integrated graphics are different, with AMD using Radeon 840M and Intel using UHD Graphics 64EU. Sockets are incompatible: AMD uses AMD Socket FP8, while Intel uses Intel BGA 1744. The release dates differ, with Intel launching on 2024-01-07 and AMD on 2026-01-04. The Intel part has a launch MSRP of $426; the AMD part has no launch MSRP recorded.

The Verdict

The benchmark data is unambiguous. The AMD Ryzen AI 7 445 outperforms the Intel Core 3 100U in 14 of 15 shared tests, with an average benchmark score of 26936 versus 16148. The AMD processor sits at the 79th percentile among all CPUs, while the Intel part sits at the 70th. The AMD part is 61% ahead in Cinebench R15 multi-core, 69.3% ahead in Cinebench R15 single-core, and 100.5% ahead in extended instructions. The only Intel win is a 0.3% margin in Cinebench R23 multi-core, which is negligible in practical terms.

For anyone choosing between these two mobile processors, the data points to the AMD Ryzen AI 7 445 for essentially all measured workloads. It delivers higher multi-thread performance, higher single-core performance in most tests, and dramatically better results in compression, encryption, sorting, and math-heavy tasks. The Intel Core 3 100U does have a lower TDP of 15 W versus 28 W, which may matter for power-constrained designs, but the performance trade-off is severe. The Intel part also offers more L3 cache (10 MB versus 4 MB) and a higher boost clock (4.70 GHz versus 4.60 GHz), yet these do not translate into benchmark wins.
