AMD Ryzen AI 7 445 vs Intel Core i7-1280P Comparison

Where Each One Wins

The benchmark split is decisive: the Intel Core i7-1280P takes 10 of the 15 recorded head-to-head tests, while the AMD Ryzen AI 7 445 wins 5. This is not a close contest in overall workload coverage, but the wins are highly directional. The AMD part dominates single-threaded performance and extended instruction throughput, while the Intel part sweeps nearly every heavily threaded or math-heavy workload.

For productivity and content creation, the Intel Core i7-1280P is the clear choice. Its multi-core Cinebench scores are consistently higher, and its PassMark multithread score of 20168 beats the AMD's 18115 by 10.2%. The Intel part also leads in integer math by 22.7%, floating-point math by 23.4%, and physics by 30.8%. Those are large, systematic advantages in compute-bound tasks.

For single-thread-sensitive applications, the AMD Ryzen AI 7 445 is the better pick. Its Cinebench R23 single-core score of 1806 beats the Intel's 1651 by 9.4%, and its PassMark single-thread score of 3591 beats 3316 by 8.3%. The AMD part also wins extended instructions by 22.7%, a sign of strong SIMD efficiency for workloads that use modern instruction sets.

The middle ground is mixed. In data compression, the Intel part wins by a narrow 2.2%, and in random string sorting it wins by 3.4%. Encryption heavily favors Intel at 20.2%, but prime number finding shows the largest gap of all at 34.9% in Intel's favor. The AMD part has no answer in those math-heavy PassMark subtests.

Overall, the database shows a classic split: Intel for parallel throughput, AMD for per-core efficiency and instruction-level agility. The AMD Ryzen AI 7 445 sits at the 79th percentile of all CPUs, while the Intel Core i7-1280P sits at the 78th. Their average benchmark scores are close, 26936 vs 26469, but the distribution of wins is lopsided.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI 7 445 uses the Zen 5 architecture, codenamed Gorgon Point, and is built on a 4 nm TSMC process. The Intel Core i7-1280P uses Alder Lake, codenamed Alder Lake-P, on Intel's 10 nm process. The Intel die is 217 mm²; the AMD die size is not recorded.

Core counts differ sharply. The AMD part has 6 cores and 12 threads. The Intel part has 14 cores and 20 threads, a hybrid configuration typical of Alder Lake. This explains much of the multi-thread advantage: the Intel part simply has more execution resources.

Cache layouts are also distinct. The AMD part has 80 KB of L1 per core, 1 MB of L2 per core, and only 4 MB of L3 total. The Intel part has 80 KB of L1 per core, 1.25 MB of L2 per core, and 24 MB of shared L3. The six-fold L3 difference (24 MB vs 4 MB) is a major factor in the Intel part's lead in data-heavy parallel workloads.

Memory support diverges. The AMD part supports DDR5 and LPDDR5X, while the Intel part supports DDR4 and DDR5. The AMD part has a recorded memory bandwidth of 89.6 GB/s; the Intel bandwidth is not recorded. The AMD part supports ECC memory; the Intel part does not. Both use dual-channel memory buses.

PCIe connectivity differs. The AMD part offers Gen 4 with 14 CPU-only lanes. The Intel part offers Gen 4 with 20 CPU-only lanes. The Intel part has more headroom for expansion.

Integrated graphics differ: the AMD part uses Radeon 840M, the Intel part uses Iris Xe 96EU. No benchmark data exists for either GPU in this pack, so no performance comparison is possible.

The process node difference is significant. The AMD part's 4 nm TSMC process is much more advanced than Intel's 10 nm node. This likely contributes to the AMD part's single-thread efficiency, despite having fewer cores.

Head-to-Head Benchmarks

The largest Intel win is in PassMark find prime numbers, where it scores 86 against the AMD's 56, a 34.9% advantage. This is a pure CPU throughput test, and the Intel part's extra cores and threads dominate. Next is PassMark physics at 30.8% (1411 vs 976), followed by floating-point math at 23.4% (51355 vs 39362) and integer math at 22.7% (75485 vs 58332). These are all parallel compute tasks where core count matters more than per-core speed.

In Cinebench R15 multi-core, the Intel part wins 2112 vs 1723, an 18.4% margin. In Cinebench R23 multi-core, it wins 11666 vs 10590, a 9.2% margin. The R15 gap is larger than R23, suggesting the Intel part scales better in shorter, less memory-intensive workloads. Data encryption shows a 20.2% Intel win (13179 vs 10519). Multithread overall is 10.2% in Intel's favor (20168 vs 18115).

The AMD wins are concentrated in single-thread tests. Cinebench R23 single-core shows 1806 vs 1651, a 9.4% lead. Cinebench R15 single-core shows 254 vs 238, a 6.7% lead. PassMark single-thread (and singlethread, same score) shows 3591 vs 3316, an 8.3% lead. The extended instructions test is the AMD part's biggest outright win at 22.7% (15826 vs 12897).

Data compression is nearly a tie: Intel wins 220621 vs 215812, just 2.2% apart. Random string sorting is also close: Intel wins 24308 vs 23488, a 3.4% margin. These two tests show that the AMD part can compete in memory-latency-sensitive tasks despite its smaller L3 cache.

The pattern is consistent. When the workload is single-threaded or uses advanced instruction sets, the AMD Ryzen AI 7 445 wins by 6.7% to 22.7%. When the workload is multi-threaded or math-intensive, the Intel Core i7-1280P wins by 9.2% to 34.9%.
