AMD Ryzen AI 5 PRO 440 vs AMD Ryzen AI 7 445 Comparison

Head-to-Head Benchmarks

The recorded data shows a clean sweep for the AMD Ryzen AI 5 PRO 440 across every benchmark in the comparison set. The Ryzen AI 5 PRO 440 wins all 11 head-to-head tests, while the Ryzen AI 7 445 records zero wins. The margins vary from modest to substantial, and the pattern is consistent across integer, floating-point, and memory-sensitive workloads.

The largest single advantage appears in prime number computation. The Ryzen AI 5 PRO 440 scores 77 in the find prime numbers test, against 56 for the Ryzen AI 7 445. That works out to a 37.5% advantage, the biggest delta in the entire comparison. For workloads that hammer through prime generation, the PRO 440 is clearly the stronger part.

Data compression and encryption also favor the PRO 440 by wide margins. In data compression, the PRO 440 scores 256420 against 215812, a lead of 18.8%. In data encryption, the PRO 440 scores 12418 versus 10519, an 18.1% edge. These are the kinds of workloads that benefit from faster memory access and larger cache, and the numbers reflect that.

The multithreaded PassMark score tells a similar story. The PRO 440 records 21054, while the AI 7 445 records 18115. That is a 16.2% advantage. The extended instructions test shows a 16.6% lead (18456 versus 15826), and random string sorting comes in at 16% ahead (27252 versus 23488). Physics simulation shows a 14.7% gap (1119 versus 976).

Integer math favors the PRO 440 by 13.1% (65991 versus 58332), and floating-point math shows a smaller but still clear 9.1% advantage (42934 versus 39362). The single-thread results are the closest of all. The PRO 440 scores 3785, while the AI 7 445 scores 3591, a 5.4% edge. That is a meaningful single-core lead, though not as dramatic as the multi-threaded gaps.

The average benchmark scores confirm the overall picture. The Ryzen AI 5 PRO 440 has an average score of 41208, while the Ryzen AI 7 445 sits at 26936. The PRO 440 also holds an 87th percentile ranking among all CPUs, compared to the 79th percentile for the AI 7 445. These are not close numbers; they indicate two processors in different performance tiers despite the similar naming scheme.

Architecture Differences

Both processors share the same foundation. They are built on AMD's Zen 5 architecture with the Gorgon Point codename, fabricated on TSMC's 4 nm process node. Both use the AMD Socket FP8, have 6 cores and 12 threads, and run at a 28 W TDP. Both support DDR5 and LPDDR5X memory in a dual-channel configuration, with a memory bandwidth of 89.6 GB/s. ECC memory is supported on both. Both ship with the Radeon 840M integrated graphics and are classified as mobile parts with active production status.

The differences begin with the generation label. The Ryzen AI 5 PRO 440 is listed under the Ryzen AI PRO 400 generation, which combines Zen 5 and Zen 5c cores. The Ryzen AI 7 445 is listed under the Ryzen AI 400 generation, also with Zen 5 and Zen 5c. That naming distinction does not change the core count or thread count, but it does align with other specification gaps.

Clock speeds differ. The PRO 440 has a base clock of 2.00 GHz and a boost clock of 4.80 GHz. The AI 7 445 also has a base clock of 2.00 GHz, but its boost clock is lower at 4.60 GHz. That 200 MHz difference in boost clock contributes directly to the single-thread performance gap.

Cache configuration is another major split. The PRO 440 carries 80 KB of L1 cache per core and 1 MB of L2 cache per core, identical to the AI 7 445. The L3 cache, however, is doubled: the PRO 440 has 8 MB, while the AI 7 445 has only 4 MB. That extra L3 cache explains much of the PRO 440's advantage in data compression, encryption, and random string sorting, all of which benefit from larger working sets residing in cache.

The PCIe configuration also differs. The PRO 440 offers PCIe Gen 4 with 16 lanes for the CPU, while the AI 7 445 offers PCIe Gen 4 with 14 lanes. That is a two-lane difference, which may matter for platforms that need extra connectivity for storage or other peripherals.

Die size is only recorded for the PRO 440 at 195 mm². The die size for the AI 7 445 is not listed in the database. Transistor counts are unavailable for both parts.

The release dates are identical: both are listed as 2026-01-04. Neither part has a launch MSRP recorded. Both are locked multipliers, so overclocking is not supported on either.

The Verdict

The benchmark data is unambiguous. The AMD Ryzen AI 5 PRO 440 outperforms the AMD Ryzen AI 7 445 in every recorded test, with deltas ranging from 5.4% in single-thread workloads to 37.5% in prime number finding. The PRO 440 delivers a higher boost clock, double the L3 cache, and two additional PCIe lanes, all while maintaining the same TDP, core count, and thread count.

The AI 7 445 has no benchmark wins in this dataset. Its only advantages are a lower boost clock and a smaller cache, which are not advantages at all for performance. The AI 7 445 does carry a different generation label, but that has not translated into any measurable performance benefit in the recorded tests.

For anyone choosing between these two parts strictly on the data, the Ryzen AI 5 PRO 440 is the stronger processor. It is faster in single-thread and multi-thread workloads, better with cache-sensitive data, and more capable in encryption and compression tasks. The AI 7 445 does not offer any performance redeeming feature in the database.

The percentile rankings reinforce the same conclusion. The PRO 440 sits at the 87th percentile among all CPUs, while the AI 7 445 sits at the 79th percentile. That is an eight-point gap, and it aligns with the average score difference of roughly 14,000 points.

Where Each One Wins

The Ryzen AI 5 PRO 440 wins in every category recorded in the database. There is no test in this comparison where the Ryzen AI 7 445 comes out ahead. That said, the margin of victory varies by workload type, and that variation is instructive.

For single-thread applications, the PRO 440 leads by 5.4%. That is a modest but real advantage, driven by the higher boost clock. Software that depends on one or two fast cores, such as older games or lightly threaded productivity tools, will see a small but measurable improvement on the PRO 440.

For multi-threaded workloads, the PRO 440 leads by 16.2% in the PassMark multithread test. Rendering, video encoding, and other parallel tasks benefit from the larger L3 cache and the higher boost clock, even though the core and thread counts are identical. The data suggests the PRO 440 sustains better performance under load.

For encryption and compression, the PRO 440 leads by 18.1% and 18.8% respectively. These workloads are highly cache-sensitive, and the PRO 440's 8 MB of L3 cache versus the AI 7 445's 4 MB makes a substantial difference. File archiving, disk encryption, and database operations fall into this category.

For prime number finding, the PRO 440 leads by 37.5%. This is the largest gap in the dataset. Prime computation stresses branch prediction and integer throughput, and the PRO 440's architecture handles it far better.

For floating-point math, the PRO 440 leads by 9.1%. Scientific simulations and certain financial calculations will favor the PRO 440, though the gap is narrower than in integer-heavy workloads.

The Ryzen AI 7 445 does not win anywhere in this dataset. Its lower boost clock and halved L3 cache put it behind in every measured category. If the AI 7 445 has a use case in this comparison, the database does not show it.
