AMD Ryzen 9 9950X vs AMD Ryzen AI 5 440G Comparison

Head-to-Head Benchmarks

The benchmark data is unambiguous: the AMD Ryzen 9 9950X wins all 11 shared tests against the AMD Ryzen AI 5 440G. The largest margin appears in prime number finding, where the 9950X scores 345 versus 90, a 283.3% advantage. This pattern of dominance holds across every workload category, from integer math to floating-point math to memory-oriented tasks.

In multi-threaded throughput, the 9950X scores 66030 in PassMark multithread against the 440G's 23487, a 181.1% lead. The gap widens further in encryption, where the 9950X records 44366 versus 13585, a 226.6% delta. Extended instruction workloads show a 246.6% difference (71564 versus 20648), while floating-point math delivers a 248% margin (159063 versus 45711). Integer math follows at 239.8% (242097 versus 71251).

Data compression shows a 206.3% advantage for the 9950X (896544 versus 292735), and random string sorting comes in at 203.4% (94368 versus 31106). Physics simulation scores 3279 against 1329, a 146.7% lead. The narrowest gap is single-thread performance: the 9950X scores 4737 versus 4060, a 16.7% advantage. This single-thread result indicates that the 9950X's per-core efficiency is solid but not overwhelming; the massive overall score differences stem primarily from core count and thread scaling.

The average benchmark score tells the same story: the 9950X averages 74640 across all recorded tests, while the 440G averages 46187. In the database percentile rankings, the 9950X sits at the 94th percentile of all CPUs, while the 440G ranks at the 89th percentile. The 9950X's nearest rivals include the AMD Ryzen 7 PRO 9745 (0.2% lower average), the AMD Ryzen AI 9 HX PRO 475 (0.2% higher), the AMD EPYC 4545P (1% lower), and the Intel Core Ultra 9 285 (1.1% lower). The 440G's nearest rivals are the Intel Core i9-13900HX (0.2% higher average), the Intel Core Ultra 5 235 (0.3% higher), the AMD Ryzen AI 9 HX 375 (0.3% higher), and the AMD EPYC 4364P (0.5% higher). This places the 440G in a competitive mid-range cluster, whereas the 9950X sits near the top of desktop performance.

Architecture Differences

Both processors use the Zen 5 architecture and are fabricated on TSMC's 4 nm process node. The 9950X carries the Granite Ridge codename and belongs to the 9000 series, while the 440G uses the Gorgon Point codename and belongs to the Ryzen AI 400 generation, which combines Zen 5 and Zen 5c cores. The 9950X is a pure Zen 5 design with 16 cores and 32 threads, whereas the 440G has 6 cores and 12 threads.

Cache hierarchy differs substantially. Both have 80 KB of L1 per core and 1 MB of L2 per core, but the 9950X has 64 MB of L3 cache, while the 440G has only 8 MB. This eightfold difference in L3 capacity is significant for workloads that repeatedly access large datasets.

The 9950X uses 16,630 million transistors across a dual-die configuration with two 70.6 mm² chiplets. The 440G is a monolithic 195 mm² die. Both support DDR5 memory with dual-channel buses and identical memory bandwidth of 89.6 GB/s. Both also support ECC memory.

PCIe connectivity differs: the 9950X provides Gen 5 with 24 lanes (CPU only), while the 440G provides Gen 4 with 12 lanes (CPU only). Integrated graphics also differ: the 9950X includes Radeon Graphics, whereas the 440G includes the Radeon 840M. Both processors are unlocked for multiplier adjustment, and both are classified as active production desktop parts. Clock speeds show a clear split: the 9950X runs at a 4.30 GHz base and 5.70 GHz boost, while the 440G runs at 2.00 GHz base and 4.80 GHz boost. Thermal design power is 170 watts for the 9950X and 65 watts for the 440G.

Where Each One Wins

The 9950X wins everywhere in the recorded benchmark set, but the size of each win varies by workload type. The largest advantages appear in compute-heavy, highly parallel tasks. Prime number finding, floating-point math, extended instructions, and encryption all show deltas above 226%. These workloads scale almost linearly with core count and thread count, which explains the 9950X's 16-core, 32-thread configuration dominating the 440G's 6-core, 12-thread setup.

Multi-threaded workloads in general are the 9950X's strongest territory. PassMark multithread shows a 181.1% lead, and the average score gap (74640 versus 46187) reflects that most tests in the database are sensitive to thread scaling. Data compression and random string sorting, both of which benefit from larger caches and more cores, show leads of 206.3% and 203.4% respectively. Physics simulation, which often favors higher core counts, shows a 146.7% advantage.

The 440G's closest showing is in single-thread performance. Its 4060 score trails the 9950X's 4737 by only 16.7%. This suggests that for lightly threaded applications, the 440G's per-core architecture is reasonably competitive, even though its base clock is much lower at 2.00 GHz versus 4.30 GHz. The boost clock difference (4.80 GHz versus 5.70 GHz) is notable, yet the single-thread gap remains modest in percentage terms.

For users whose workloads are dominated by a few threads, the 440G is not severely penalized. However, for any workload that engages more than a handful of threads, the 9950X's core and cache advantages become decisive. The 440G's 8 MB L3 cache is a fraction of the 9950X's 64 MB, and that cache deficit compounds in data-heavy parallel tasks.

The Verdict

The recorded data supports a straightforward conclusion: the AMD Ryzen 9 9950X is the superior processor for any workload that benefits from high core counts, large cache, or sustained multi-threaded throughput. It leads in all 11 shared benchmark tests, with margins ranging from 16.7% in single-thread to 283.3% in prime number finding. Its 64 MB L3 cache, 16 cores, and 32 threads give it a structural advantage that the 440G cannot offset.

The AMD Ryzen AI 5 440G is not without merit. Its single-thread score of 4060 is within 16.7% of the 9950X, and its 65 W TDP suggests it is a far more efficient part for lighter workloads. It also uses the same Zen 5 architecture and 4 nm process, so per-core instruction efficiency is comparable. For users who run only lightly threaded applications and prioritize lower power draw, the 440G is a viable option.

However, the database shows no benchmark where the 440G wins. Its 6 cores, 12 threads, and 8 MB L3 cache place it in a mid-range performance tier, as confirmed by its nearest rivals (Intel Core i9-13900HX, Intel Core Ultra 5 235, AMD Ryzen AI 9 HX 375, AMD EPYC 4364P), all within 0.5% of its average score. The 9950X, by contrast, competes with the AMD Ryzen 7 PRO 9745, AMD Ryzen AI 9 HX PRO 475, AMD EPYC 4545P, and Intel Core Ultra 9 285, all within 1.1% of its average.

The verdict is clear: the 9950X is the choice for compute-intensive tasks, multi-threaded rendering, data processing, and any workload that can use 32 threads. The 440G is the choice for basic desktop usage, low-power systems, and tasks where single-thread performance is sufficient. The data does not support any scenario where the 440G outperforms the 9950X in the recorded tests.
