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

Both processors share the same Gorgon Point codename and 4 nm TSMC manufacturing process, yet the recorded data separates them into different market segments with distinct performance profiles. The AMD Ryzen AI 5 440G targets desktops with a 65 W TDP on Socket AM5, while the AMD Ryzen AI 7 445 is a mobile part with a 28 W TDP on Socket FP8. Despite identical core and thread counts, the benchmark results show a consistent advantage for the desktop-oriented chip across every measured workload.

Where Each One Wins

The use-case split is straightforward: the AMD Ryzen AI 5 440G wins every one of the 11 head-to-head benchmark comparisons. The AMD Ryzen AI 7 445 does not record a single victory in the database. This does not mean the mobile chip is weak; rather, its strengths lie in efficiency and platform flexibility rather than raw throughput. The Ryzen AI 7 445 uses 28 W compared to the desktop part's 65 W, which makes it suited for thin-and-light systems where thermal and power budgets are limited. Its support for LPDDR5X memory alongside DDR5 gives mobile designers more options for compact memory layouts.

The desktop Ryzen AI 5 440G delivers higher scores in every passmark test, from single-thread performance to multithreaded workloads. For tasks that rely on heavy computation, such as prime number finding, physics simulations, or integer math, the desktop chip is the clear choice. The mobile chip still provides capable performance for everyday productivity, but the data consistently favors the desktop part when performance is the priority. The Ryzen AI 7 445's lower TDP and unlocked multiplier status (it is locked, unlike the desktop part's unlocked multiplier) suggest it is designed for stable, efficient operation rather than overclocking or maximum throughput.

Head-to-Head Benchmarks

The largest margin in the database appears in the passmark find prime numbers test. The Ryzen AI 5 440G scores 90 compared to the Ryzen AI 7 445's 56, a delta of 60.7%. This test is highly sensitive to single-thread efficiency and clock speed, and the desktop chip's higher boost clock likely contributes to this substantial gap.

Data compression shows a 35.6% advantage for the desktop part, with scores of 292735 versus 215812. This workload benefits from both core throughput and cache size, and the Ryzen AI 5 440G has double the L3 cache (8 MB versus 4 MB). Physics simulation follows a similar pattern: the desktop chip scores 1329 against 976, a 36.2% delta. Random string sorting shows a 32.4% difference (31106 versus 23488), and extended instructions show a 30.5% gap (20648 versus 15826).

Multithreaded performance is a key differentiator. The passmark multithread test shows 23487 for the desktop part versus 18115 for the mobile chip, a 29.7% lead. Data encryption follows with 13585 versus 10519, a 29.1% delta. Integer math shows 71251 against 58332, a 22.1% advantage. Floating point math has the smallest margin among the heavy compute tests: 45711 versus 39362, a 16.1% delta.

Single-thread performance is the closest comparison. The Ryzen AI 5 440G scores 4060 while the Ryzen AI 7 445 scores 3591, a 13.1% delta. This smaller gap reflects the relatively similar architecture and core design, but the desktop chip's higher boost clock still delivers a clear win. Across all 11 benchmarks, the desktop part never falls behind, and its average benchmark score of 46187 sits 71.4% above the mobile chip's 26936.

Specification Differences

The two processors diverge in several key specifications beyond their benchmark scores. The Ryzen AI 5 440G has a TDP of 65 W, while the Ryzen AI 7 445 consumes 28 W. This 37 W difference explains much of the performance gap, as the desktop part has more thermal headroom for sustained boost clocks.

The socket is another major difference. The desktop chip uses AMD Socket AM5, which is designed for desktop motherboards with more power delivery and expansion options. The mobile chip uses AMD Socket FP8, a BGA-style socket for laptops. The desktop part has an unlocked multiplier, allowing overclocking, while the mobile chip's multiplier is locked.

Memory support differs slightly. Both support DDR5, but the Ryzen AI 7 445 adds LPDDR5X support for mobile applications. Both use dual-channel memory with 89.6 GB/s bandwidth. PCIe lanes also differ: the desktop chip has 12 Gen 4 lanes, while the mobile chip has 14 Gen 4 lanes. The integrated graphics are identical: both use the Radeon 840M.

The release dates differ, with the Ryzen AI 7 445 appearing on 2026-01-04 and the Ryzen AI 5 440G on 2026-02-28. The desktop chip has a die size of 195 mm², while the mobile chip's die size is not recorded. The part numbers are distinct: 100-000001918 for the desktop, 100-000001935 for the mobile.

Architecture Differences

Both processors share the Gorgon Point codename and the Ryzen AI 400 generation, which uses a combination of Zen 5 and Zen 5c cores. The process node is 4 nm from TSMC for both. The architecture field is empty for the Ryzen AI 5 440G but explicitly listed as Zen 5 for the Ryzen AI 7 445, though the generation string indicates both use Zen 5 / Zen 5c.

The cache hierarchy shows the clearest architectural divergence. Both have 80 KB L1 per core and 1 MB L2 per core, but the L3 cache differs: 8 MB for the desktop part versus 4 MB for the mobile part. This doubling of L3 cache in the desktop chip likely contributes to its advantages in data compression and random string sorting, workloads that benefit from larger working sets.

The desktop chip's 65 W TDP and larger die (195 mm² versus not recorded for mobile) suggest a more robust power delivery and thermal solution. The mobile chip's 28 W TDP aligns with its market segment and Socket FP8 platform. Both support ECC memory, which is unusual for consumer processors and indicates a focus on reliability in both segments.

The Verdict

The data supports a clear division of roles. The AMD Ryzen AI 5 440G is the performance leader, winning all 11 head-to-head benchmarks with deltas ranging from 13.1% in single-thread to 60.7% in prime number finding. Its 89th percentile ranking and 46187 average benchmark score place it among strong desktop processors. The nearest rivals include the Intel Core i9-13900HX (0.2% behind), the Intel Core Ultra 5 235 (0.3% behind), and the AMD Ryzen AI 9 HX 375 (0.3% behind), showing that the desktop chip competes well against both Intel and AMD offerings.

The AMD Ryzen AI 7 445 targets a different use case entirely. Its 28 W TDP and Socket FP8 platform make it suitable for mobile systems where power efficiency is critical. The 79th percentile ranking and 26936 average benchmark score still represent capable performance, as shown by its nearest rivals: the Intel Core i7-1370P (0.1% ahead), the AMD Ryzen 5 7545U (0.3% ahead), and the AMD Ryzen 7 5700G (0.4% ahead). These close margins indicate the mobile chip is competitive within its power class.

For desktop users prioritizing raw performance, the Ryzen AI 5 440G is the obvious choice. For mobile users who need a 28 W processor with LPDDR5X memory support and ECC capability, the Ryzen AI 7 445 delivers solid results without the desktop part's power requirements. The performance gap is consistent and substantial, but it is directly tied to the 37 W TDP difference and the desktop chip's larger L3 cache. Neither processor can be called a failure; they simply serve different platforms with different priorities.
