AMD Ryzen 9 9850HX vs AMD Ryzen AI 5 440G Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive sweep in favor of the AMD Ryzen 9 9850HX across all 11 benchmark comparisons. The largest margin appears in the prime number test, where the 9850HX scores 323 versus 90 for the Ryzen AI 5 440G, a 258.9% advantage. This test is highly sensitive to raw integer throughput and large core counts, so the magnitude of the gap reflects the structural difference between the two processors.

In floating-point math, the 9850HX posts 115,062 against 45,711, a 151.7% lead. Extended instruction workloads show a 160.6% gap, with scores of 53,817 versus 20,648. Integer math follows at 142.7%, with 172,943 versus 71,251. Data encryption shows a 136.6% delta, with 32,139 against 13,585. These are substantial margins in compute-heavy workloads, all favoring the 12-core part.

The multithread score is 51,722 versus 23,487, a 120.2% difference. Physics simulation, which often scales with thread count and memory bandwidth, shows a 129.8% gap at 3,054 versus 1,329. Data compression delivers 662,381 versus 292,735, a 126.3% advantage. Random string sorting shows a 125.6% gap, with 70,175 versus 31,106.

The narrowest margin is in single-thread performance. The 9850HX scores 4,461 while the 440G scores 4,060, a 9.9% difference. This indicates that while the 9850HX has a higher boost clock of 5.20 GHz versus 4.80 GHz, the per-core architecture is relatively close. The 440G uses a mix of Zen 5 and Zen 5c cores, which may explain why its single-thread result trails but does not collapse.

The average benchmark score reinforces this hierarchy. The 9850HX averages 106,413 across the recorded tests, placing it in the 97th percentile of all CPUs in the database. The 440G averages 46,187, which lands in the 89th percentile. The nearest rivals for the 9850HX include the Intel Xeon w7-3555 with an average score of 106,192, a 0.2% delta, and the Intel Xeon w7-2595X at 108,663, a -2.1% delta. The 440G sits close to the Intel Core i9-13900HX at 46,098, with a 0.2% delta, and the AMD Ryzen AI 9 HX 375 at 46,030, with a 0.3% delta. The data indicates that both processors are competitive within their respective performance tiers, but those tiers are far apart.

The Verdict

The benchmark results indicate that the AMD Ryzen 9 9850HX is the stronger processor in every measured workload. With 12 cores, 24 threads, and a boost clock of 5.20 GHz, it delivers more than double the multithread score of the 440G and a nearly 10% higher single-thread score. The 97th percentile ranking versus the 89th percentile for the 440G places them in different performance classes.

The 440G is a 6-core, 12-thread desktop part with a 65 W TDP, while the 9850HX is a 12-core, 24-thread mobile part with a 55 W TDP. Despite the lower TDP on the 9850HX, its performance is far higher. This suggests that the 9850HX is designed for workloads that demand heavy parallel processing, while the 440G targets systems where the desktop form factor and lower core count are acceptable.

For users who prioritize raw compute throughput, multithreaded rendering, data compression, encryption, or physics simulation, the 9850HX is the clear choice based on the recorded data. The 440G would only be preferable in a scenario where the desktop socket and integrated Radeon 840M graphics are more relevant than raw CPU performance, but the database does not show any CPU benchmark where the 440G wins.

Architecture Differences

The two processors share the same 4 nm TSMC process node, but their architectures diverge significantly. The 9850HX uses the Zen 5 architecture under the Fire Range codename, part of the 9000 series. The 440G uses a hybrid configuration labeled Zen 5 / Zen 5c under the Gorgon Point codename, part of the Ryzen AI 400 generation. The 440G's use of Zen 5c cores likely explains its lower single-thread score relative to the 9850HX, as those cores are optimized for density rather than maximum frequency.

The 9850HX has 12 cores and 24 threads, while the 440G has 6 cores and 12 threads. Cache capacity differs sharply: the 9850HX has 64 MB of L3 cache, versus 8 MB for the 440G. Both use 80 KB of L1 cache per core and 1 MB of L2 cache per core. The L3 difference is a major factor in the multithread and data-heavy benchmark results.

Memory support is similar on paper: both use DDR5 with dual-channel interfaces and 89.6 GB/s of memory bandwidth, and both support ECC memory. However, the PCIe configuration differs. The 9850HX uses Gen 5 with 28 lanes (CPU only), while the 440G uses Gen 4 with 12 lanes (CPU only). This gives the 9850HX substantially more I/O bandwidth for expansion and high-speed storage.

The integrated graphics also differ. The 9850HX carries a Radeon 610M, while the 440G carries a Radeon 840M. The database does not include graphics benchmarks for either, so the comparison is limited to CPU and system-level data.

The socket and market segment differ as well. The 9850HX uses AMD Socket FL1 and is classified as a mobile part, with a release date of 2025-01-05. The 440G uses AMD Socket AM5, is classified as desktop, and has a release date of 2026-02-28. The 9850HX die size is listed as 2x 70.6 mm², while the 440G has a single 195 mm² die. Transistor counts are listed for the 9850HX at 16,630 million, with no figure provided for the 440G.

Where Each One Wins

The AMD Ryzen 9 9850HX wins every recorded benchmark comparison. Its largest advantages are in prime number finding (258.9%), extended instructions (160.6%), and floating-point math (151.7%). These are workloads that benefit from the 12-core, 24-thread configuration, the 64 MB L3 cache, and the boost clock of 5.20 GHz. The data compression and encryption tests also show gains above 126%, indicating strong throughput in data-heavy tasks. The 9850HX is positioned for high-end mobile systems that need desktop-class compute performance.

The AMD Ryzen AI 5 440G does not win a single benchmark in the database. Its closest result is in single-thread performance, where it trails by 9.9%, a relatively modest gap. In all other tests, the 440G trails by more than 120%. The 440G remains a viable processor for desktop builds that require the AM5 socket and the Radeon 840M integrated graphics, but the CPU benchmark data does not show any workload where it outperforms the 9850HX.

The nearest rivals in the database provide context for each chip. The 9850HX competes with workstation-class Xeon parts, with a 0.2% delta to the Intel Xeon w7-3555 and a -2.1% delta to the Intel Xeon w7-2595X. The 440G sits alongside the Intel Core i9-13900HX and AMD Ryzen AI 9 HX 375, with deltas of 0.2% and 0.3% respectively. This confirms that the 9850HX operates in a much higher performance tier, while the 440G aligns with mid-range mobile and desktop processors.

Specification Differences

The two processors differ across nearly every major specification. The 9850HX has 12 cores and 24 threads, while the 440G has 6 cores and 12 threads.

The TDP is 55 W for the 9850HX and 65 W for the 440G, meaning the higher-core-count mobile part consumes less rated power than the desktop part.

Cache configurations differ substantially. The 9850HX has 64 MB of L3 cache, while the 440G has 8 MB. Both share 80 KB of L1 cache per core and 1 MB of L2 cache per core. Memory support is identical in type, bus width, bandwidth, and ECC capability, but PCIe support differs: Gen 5 with 28 lanes on the 9850HX versus Gen 4 with 12 lanes on the 440G.

The sockets are different: AMD Socket FL1 for the 9850HX and AMD Socket AM5 for the 440G. The process node is the same at 4 nm, with TSMC as the foundry for both. Die size differs, with the 9850HX using 2x 70.6 mm² and the 440G using a single 195 mm² die. Transistor count is listed only for the 9850HX at 16,630 million. Integrated graphics are Radeon 610M for the 9850HX and Radeon 840M for the 440G. The market segment is mobile for the 9850HX and desktop for the 440G.
