Architecture Differences

The AMD Ryzen AI 7 445 uses the Zen 5 architecture under the Gorgon Point codename, built on a 4 nm process at TSMC. Its generation is listed as Ryzen AI 400 (Zen 5 / Zen 5c). The Intel Core 3 305 uses the Wildcat Lake codename, built on a 3 nm process at Intel, with its generation listed as Core 3 (Wildcat Lake). The process node difference is small, but the foundry split is notable: TSMC for AMD, Intel for Intel.

Cache layout differs substantially. The AMD chip allocates 80 KB of L1 per core and 1 MB of L2 per core, with 4 MB of L3. The Intel chip uses 192 KB of L1, 2.5 MB of L2, and 6 MB of shared L3. For workloads that depend on a large shared last-level cache, the Intel part has more capacity. For per-core L2 access, the AMD part offers 1 MB per core, which can reduce latency for frequently accessed per-core data.

Memory architecture also separates the two. The AMD Ryzen AI 7 445 supports dual-channel memory with 89.6 GB/s of bandwidth. The Intel Core 3 305 supports single-channel memory with 59.7 GB/s of bandwidth. That is a significant bandwidth gap for memory-sensitive tasks. The AMD chip also supports ECC memory, while the Intel chip does not. Both support DDR5 and LPDDR5X.

PCIe lane counts differ as well. The AMD part provides Gen 4 with 14 lanes (CPU only), while the Intel part provides Gen 4 with 6 lanes (CPU only). Integrated graphics differ: the AMD chip uses Radeon 840M, while the Intel chip uses Intel Xe3 Graphics (1 Xe). The AMD chip has 12 threads versus 6 threads on Intel, which stems from simultaneous multithreading on the AMD side. Neither chip has an unlocked multiplier.

Head-to-Head Benchmarks

The database records 15 head-to-head comparisons between these two processors, with the AMD Ryzen AI 7 445 winning 7 and the Intel Core 3 305 winning 8. The biggest margins show a clear split between integer-heavy and floating-point-heavy workloads.

The AMD Ryzen AI 7 445 dominates in passmark integer math with a score of 58332 against 32295 for Intel, a 80.6% advantage. That is the single largest gap in either direction. Data compression also favors AMD heavily: 215812 versus 146857, a 47% lead. Random string sorting goes to AMD at 23488 versus 17623, a 33.3% margin. The AMD chip also wins Cinebench R15 multicore at 1723 versus 1322, a 30.3% lead, and Cinebench R15 singlecore at 254 versus 186, a 36.6% lead. Extended instructions favor AMD at 15826 versus 13543, a 16.9% margin, and passmark multithread goes to AMD at 18115 versus 15439, a 17.3% lead.

The Intel Core 3 305 wins the more modern Cinebench R23 tests. In R23 multicore, Intel scores 13123 against 10590 for AMD, a 19.3% advantage. In R23 singlecore, Intel scores 1852 against 1806, a 2.5% lead. Passmark single thread also goes to Intel at 3977 versus 3591, a 9.7% margin. Floating point math favors Intel at 42284 versus 39362, a 6.9% lead. Data encryption goes to Intel at 11019 versus 10519, a 4.5% margin. Physics favors Intel at 1233 versus 976, a 20.8% lead. The largest Intel win is in find prime numbers: 115 versus 56, a 51.3% advantage.

These results indicate that AMD's chip excels at integer operations, compression, sorting, and older Cinebench versions, while Intel's chip leads in single-threaded PassMark tests, floating-point math, physics, encryption, and newer Cinebench R23 workloads. The Cinebench R15 and R23 results move in opposite directions, which suggests the two processors respond differently to the workload changes between those benchmark versions.

The Intel part has a launch MSRP of $309; the AMD part has no launch MSRP in the database. Both are marked as active production mobile parts, and neither has an unlocked multiplier.

The Verdict

The recorded data shows two processors with nearly opposite strengths. The AMD Ryzen AI 7 445 delivers far higher multi-threaded integer performance, compression throughput, and memory bandwidth, supported by 12 threads, dual-channel memory, and 89.6 GB/s of bandwidth. It wins passmark multithread by 17.3% and integer math by 80.6%. The Intel Core 3 305 counters with stronger single-threaded PassMark performance, better floating-point math, better physics results, and a decisive win in Cinebench R23 multicore despite having only 6 threads.

The Intel chip wins 8 of 15 head-to-head tests, but the AMD chip wins the tests with the largest average margins. The AMD part also has a much higher average benchmark score of 26936 versus 18302, and a higher percentile ranking at 79 versus 72. The Intel part sits in a lower performance tier, with nearest rivals around the Intel Core i3-14100 and AMD Ryzen 5 2600E, while the AMD part sits near the Intel Core i7-1370P and AMD Ryzen 7 5700G.

The Intel Core 3 305 does hold a notable advantage in Cinebench R23 multicore, scoring 13123 versus 10590 for AMD, a 19.3% margin. That result is surprising given the thread count disadvantage, and it suggests the Intel architecture handles that specific workload much more efficiently. However, the AMD part wins Cinebench R15 multicore by 30.3%, so the two Cinebench versions tell conflicting stories. The physics test also favors Intel by 20.8%, and find prime numbers favors Intel by 51.3%, which points to strong per-core execution on the Intel chip for certain math patterns.

For general throughput, the AMD Ryzen AI 7 445 is the stronger part. The 12 threads, dual-channel memory, higher bandwidth, and higher average score make it the better choice for multi-threaded integer work, compression, sorting, and sustained parallel loads. The Intel Core 3 305 is the better choice for workloads that match its wins: single-threaded PassMark, floating-point math, physics, encryption, and Cinebench R23. Its lower 15 W TDP also indicates a more power-efficient design, though the database does not provide wattage measurements to confirm real-world draw.

Where Each One Wins

The AMD Ryzen AI 7 445 wins in passmark multithread, integer math, data compression, random string sorting, extended instructions, Cinebench R15 multicore, and Cinebench R15 singlecore. These are workloads that benefit from higher thread counts, higher clock speeds, and larger memory bandwidth. The 12 threads and dual-channel memory support give it an edge in parallel integer tasks. Data compression shows a 47% advantage, and integer math shows an 80.6% advantage, so any workload centered on integer processing or data packing should favor the AMD chip. The Cinebench R15 wins by 30.3% in multicore and 36.6% in singlecore indicate that the AMD part also has a strong per-core showing in that benchmark version.

The Intel Core 3 305 wins in Cinebench R23 multicore, Cinebench R23 singlecore, passmark single thread, floating-point math, data encryption, physics, and find prime numbers. The find prime numbers result is the standout: 115 versus 56, a 51.3% lead. That pattern suggests the Intel chip executes certain algorithmic loops much faster per clock. The physics win at 20.8% and the floating-point win at 6.9% reinforce a picture of strong scalar and floating-point performance. The Cinebench R23 multicore win at 19.3% is the largest Intel victory in a rendering-style test, and the R23 singlecore win at 2.5% shows the Intel chip also leads in the newer single-thread Cinebench test.

The split is clean. Choose the AMD Ryzen AI 7 445 for integer-heavy parallel workloads, compression, sorting, multithreaded PassMark, and memory-bandwidth-sensitive tasks. Choose the Intel Core 3 305 for single-threaded PassMark, floating-point math, physics, encryption, and Cinebench R23 workloads. The database does not record gaming or battery-life results, so those areas remain outside this comparison.
