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

Head-to-Head Benchmarks

The benchmark database shows a decisive sweep in favor of the AMD Ryzen 9 9900X across all recorded PassMark comparisons. The Ryzen 9 9900X wins 11 head-to-head tests, while the AMD Ryzen AI 5 440G records zero wins. The margins, however, vary dramatically depending on the workload.

The largest gap appears in prime number finding, where the 9900X scores 436 compared to 90 for the 440G, a 384.4% advantage. This test relies heavily on integer throughput and cache behavior, and the 9900X's configuration simply overwhelms the smaller chip. Extended instruction performance also shows a massive gap: 55,243 versus 20,648, a 167.5% delta. This suggests the 9900X handles AVX-style workloads with far greater efficiency.

Floating-point math follows closely, with the 9900X scoring 120,083 against 45,711, a 162.7% lead. Integer math tells a similar story: 181,056 versus 71,251, a 154.1% difference. Physics calculations show 3,381 versus 1,329, a 154.4% margin. Data encryption shows 33,421 against 13,585, a 146% gap. The 9900X also dominates data compression, scoring 683,579 against 292,735, a 133.5% lead, and random string sorting, 72,013 versus 31,106, a 131.5% margin.

The multithreaded PassMark score, which aggregates many of these workloads, shows 54,643 for the 9900X versus 23,487 for the 440G, a 132.7% advantage. This reflects the core count difference: 12 cores and 24 threads versus 6 cores and 12 threads.

The most interesting result is single-thread performance. Here the 9900X wins by only 15.1%, scoring 4,672 against 4,060. Both processors use the Zen 5 architecture, which explains why the per-core gap is relatively modest. The 9900X's higher boost clock, 5.60 GHz versus 4.80 GHz, accounts for most of this difference. Single-threaded workloads rarely stress memory bandwidth or cache capacity, so the 9900X cannot fully leverage its larger L3 cache in this test.

The average benchmark score reinforces the overall picture. The 9900X posts an average of 57,498 across all recorded benchmarks, while the 440G averages 46,187. This places the 9900X in the 92nd percentile of all CPUs in the database, while the 440G sits in the 89th percentile. Despite the lopsided head-to-head sweep, both chips rank high globally, indicating that the 440G is still a strong performer in absolute terms.

Where Each One Wins

The data splits cleanly by thread utilization. The Ryzen 9 9900X wins every multithreaded and heavily parallel workload by wide margins. Its 12-core, 24-thread configuration with 64 MB of L3 cache delivers 132.7% to 384.4% advantages across all measured PassMark categories. This makes it the clear choice for rendering, compilation, scientific computing, and any workload that scales with core count.

The Ryzen AI 5 440G, despite losing every benchmark, shows respectable single-thread capability. Its 4,060 single-thread score trails the 9900X by only 15.1%. For lightly threaded applications, the 440G's performance is much closer to the flagship chip than the multithreaded numbers suggest. Its 2.00 GHz base clock and 4.80 GHz boost clock, combined with Zen 5 cores, allow it to handle everyday tasks without a proportional penalty.

The 440G also offers integrated Radeon 840M graphics, which the database records as a feature difference. The 9900X includes Radeon Graphics, but the 440G's specific iGPU model may provide different display and media capabilities. Neither chip's integrated graphics performance is benchmarked in the head-to-head data, so any analysis of those capabilities remains qualitative.

The 440G's lower TDP of 65 watts against the 9900X's 120 watts suggests it produces less heat and requires less robust cooling. The database does not record wattage measurements for these specific chips, but the TDP figures indicate a power envelope difference that could matter for compact desktop builds.

For users who prioritize raw throughput, the 9900X wins every category. For users who need decent single-thread performance in a lower-power package, the 440G holds up reasonably well.

Architecture Differences

Both processors use TSMC's 4 nm process node and the Zen 5 architecture, but they diverge significantly in implementation. The Ryzen 9 9900X, codenamed Granite Ridge, belongs to the 9000 series and uses a dual-die design with a total die size of 2x 70.6 mm². The Ryzen AI 5 440G, codenamed Gorgon Point, uses a monolithic die measuring 195 mm².

The transistor count tells part of the story. The 9900X packs 16,630 million transistors across its two dies, while the database records no transistor count for the 440G. The 9900X's dual-die approach allows it to reach 12 cores, while the 440G's single die accommodates 6 cores.

Cache configurations differ substantially. The 9900X provides 64 MB of L3 cache, while the 440G delivers only 8 MB. Both chips use 80 KB of L1 cache per core and 1 MB of L2 cache per core. The 9900X's 8x larger L3 cache explains its dominance in cache-sensitive workloads like prime number finding and extended instructions.

Memory support is identical: both use DDR5 with dual-channel buses and 89.6 GB/s of theoretical bandwidth. Both support ECC memory, which matters for reliability-focused desktop builds.

PCIe connectivity differs. The 9900X offers Gen 5 with 24 CPU lanes, while the 440G provides Gen 4 with 12 CPU lanes. This affects expansion options for GPUs, NVMe storage, and other add-in cards. Gen 5 bandwidth is double that of Gen 4, so the 9900X supports faster storage and graphics interfaces.

Integrated graphics differ in model designation: the 9900X lists Radeon Graphics, while the 440G specifies Radeon 840M. Both use the same AM5 socket, and both have unlocked multipliers, allowing overclocking. The 440G's generation is listed as Ryzen AI 400 series with a mixed Zen 5 / Zen 5c core arrangement, while the 9900X uses standard Zen 5 cores throughout.

The 9900X's boost clock reaches 5.60 GHz, compared to the 440G's 4.80 GHz. Base clocks show an even larger gap: 4.40 GHz versus 2.00 GHz. The 440G's low base clock suggests aggressive power management, likely tied to its 65-watt TDP.

The Verdict

The recorded data points to a straightforward conclusion: the Ryzen 9 9900X outperforms the Ryzen AI 5 440G in every measured benchmark category. The smallest margin is 15.1% in single-thread performance, and the largest reaches 384.4% in prime number finding. The 9900X's 12 cores, 24 threads, and 64 MB L3 cache provide overwhelming advantages in multithreaded workloads.

The 440G's 6 cores and 12 threads, combined with only 8 MB of L3 cache, cannot match the 9900X in parallel processing. Its single-thread score of 4,060 is respectable but still trails the 9900X's 4,672. The 440G does offer a lower TDP of 65 watts versus 120 watts, which could reduce cooling requirements and power draw in constrained builds.

The 9900X also provides more PCIe lanes with newer Gen 5 support, 24 lanes versus the 440G's 12 Gen 4 lanes. This makes the 9900X better suited for high-bandwidth peripherals. Both chips use the AM5 socket, both support DDR5 with ECC, and both have unlocked multipliers.

The 440G's higher percentile ranking, 89th versus 92nd, shows that it remains a capable processor in the broader market context. Its nearest rivals include the Intel Core i9-13900HX and AMD Ryzen AI 9 HX 375, with delta percentages of 0.2% and 0.3% respectively. The 9900X's nearest rivals are the AMD EPYC 9015 and Intel Core i9-14900, with delta percentages of -0.1% and -1.1%.

For users who need maximum throughput, the 9900X is the clear choice. For users who prioritize lower power draw and still want usable single-thread performance, the 440G offers a more modest but valid option. The data does not record any benchmark where the 440G wins, so any preference for it must come from factors outside the measured performance metrics.
