AMD Ryzen 9 9900X3D vs AMD Ryzen AI 5 440G Comparison

Head-to-Head Benchmarks

The data shows a decisive sweep for the AMD Ryzen 9 9900X3D, which records 11 wins across all matched benchmarks, with zero wins for the AMD Ryzen AI 5 440G. The largest margins appear in compute-heavy workloads rather than light-thread tasks.

The most extreme difference is in prime number finding, where the 9900X3D scores 544 against 90 for the 440G, a 504.4% advantage. This reflects the 9900X3D's substantially higher core count and larger cache. Physics simulation also shows a massive gap: 5340 versus 1329, a 301.8% lead. Both metrics point to workloads that scale strongly with parallel execution resources.

Extended instruction throughput favors the 9900X3D by 168.4%, scoring 55426 versus 20648. Floating point math shows a 161.7% lead (119622 vs 45711), while integer math trails slightly behind at 152.2% (179727 vs 71251). Data encryption shows a 145% advantage (33282 vs 13585), and multithread performance is 139.1% higher (56154 vs 23487).

Compression and sorting tasks show smaller but still substantial gaps. Data compression records 685074 versus 292735, a 134% difference, while random string sorting shows 71864 versus 31106, a 131% lead. These results indicate the 9900X3D maintains a consistent edge across memory-bandwidth-sensitive operations.

The narrowest margin appears in single-thread performance. The 9900X3D scores 4646 against 4060, a 14.4% advantage. This is the only benchmark where the two processors are relatively close, suggesting that per-core efficiency differences are modest compared to the scaling advantages of the larger processor.

Where Each One Wins

The AMD Ryzen 9 9900X3D wins in every measured category. Its 12 cores and 24 threads, combined with a 128 MB L3 cache, produce dominant results in heavy parallel workloads. The benchmark results confirm that tasks such as scientific computing, video rendering, and large-scale data processing benefit most from this configuration.

The AMD Ryzen AI 5 440G does not win any matched benchmark. Its 6 cores and 12 threads, with an 8 MB L3 cache, place it behind in all recorded tests. The single-thread gap of 14.4% is the closest it gets, which means lighter workloads like basic productivity or web browsing would show a smaller difference, but still favor the 9900X3D.

For workloads that are not parallel, such as typical office applications or light scripting, the 440G's smaller margin in single-thread performance reduces the perceived gap. However, the data does not record a single test where the 440G outperforms the 9900X3D, so its only advantage is lower power draw and potentially simpler cooling requirements.

Integrated graphics are Radeon Graphics on the 9900X3D and Radeon 840M on the 440G. The 9900X3D was released on 2025-01-05, while the 440G has a release date of 2026-02-28. The 9900X3D has a launch MSRP of $599; the 440G does not have a recorded launch MSRP.

Both processors fit the AMD Socket AM5, use 4 nm TSMC manufacturing, support DDR5 with dual-channel memory buses, and have 89.6 GB/s memory bandwidth. Both also support ECC memory and have unlocked multipliers. L1 and L2 caches are identical: 80 KB per core and 1 MB per core respectively.

Architecture Differences

The architecture names and die sizes distinguish these two chips. The 9900X3D uses Zen 5 architecture with the Granite Ridge codename, while the 440G uses a mixed Zen 5 / Zen 5c design with the Gorgon Point codename. The 9900X3D belongs to the Ryzen 9 generation series, whereas the 440G belongs to the Ryzen AI 400 series.

Die sizes differ substantially. The 9900X3D uses a dual-die layout with 2x 70.6 mm² dies, while the 440G uses a single 195 mm² die. The 9900X3D has 16,630 million transistors, while the 440G does not have a recorded transistor count in the database. The 9900X3D's L3 cache is 128 MB, compared to 8 MB on the 440G, a difference that significantly influences performance in cache-heavy workloads.

The 9900X3D is a desktop segment processor with an active production status. The 440G is also a desktop segment processor with active production status. Both use the 4 nm process node from TSMC. The 9900X3D's part number is 100-000001368, while the 440G's is 100-000001918.

The Verdict

The benchmark data is unambiguous: the AMD Ryzen 9 9900X3D outperforms the AMD Ryzen AI 5 440G in every recorded test. Its 11 wins with zero losses, including a 504.4% lead in prime number finding and a 301.8% lead in physics, establish it as the stronger processor for demanding workloads.

The 9900X3D suits users who need maximum parallel throughput, large cache capacity, and high boost clocks. Its 12 cores, 24 threads, 128 MB L3 cache, and 5.50 GHz boost clock deliver top-tier results in multithreaded applications, data compression, encryption, and floating point math. The 440G, with 6 cores, 12 threads, and 8 MB L3 cache, cannot match these figures.

The 440G's only recorded advantages are its lower 65 TDP and its support for Gen 4 PCIe with 12 lanes, which may appeal to builds with modest power budgets or simpler cooling requirements. Its single-thread score of 4060 is 14.4% behind the 9900X3D, so even lightly threaded tasks favor the larger chip.

Users prioritizing raw performance across all measured categories should select the 9900X3D. Users who need a lower-power desktop processor with a smaller physical footprint and are willing to accept a substantial performance deficit should consider the 440G. The data does not support any scenario where the 440G wins on performance; its appeal rests entirely on efficiency and cost considerations outside the recorded benchmarks.
