AMD Ryzen 7 8745HX vs AMD Ryzen AI 5 440G Comparison

Where Each One Wins

The recorded benchmark data splits this comparison into two distinct territories. The AMD Ryzen 7 8745HX dominates nine of the eleven tested workloads, while the AMD Ryzen AI 5 440G claims victory in exactly two: the single-thread tests. This is not a subtle margin in most cases; the 8745HX leads by double-digit percentages across nearly every multi-threaded and throughput-oriented task.

Looking at the data compression test, the 8745HX scores 363,759 against 292,735 for the 440G, a 24.3% advantage. The gap widens considerably in integer math, where the 8745HX posts 100,328 versus 71,251, a 40.8% lead. Floating-point math shows a 35.6% difference, with scores of 61,972 and 45,711 respectively. The encryption workload is even more lopsided: 21,840 versus 13,585, a 60.8% margin. Prime number finding, a workload that often stresses core count and memory latency, shows the largest relative gap at 76.7%, with scores of 159 and 90.

The multithread score, which aggregates overall parallel performance, gives the 8745HX a 34.2% lead (31,517 versus 23,487). Physics simulation, another heavily threaded workload, favors the 8745HX by 26.5% (1,681 versus 1,329). Random string sorting shows a 43% advantage for the 8745HX (44,494 versus 31,106), and extended instruction throughput favors it by 33.9% (27,638 versus 20,648).

The single-thread tests tell the opposite story. Both the passmark_single_thread and passmark_singlethread entries record 4,060 for the 440G against 3,879 for the 8745HX, a 4.5% edge for the newer part. That is the only category where the 440G leads, and the margin is modest compared to the multi-thread gaps. The average benchmark score reflects this split: 60,104 for the 8745HX versus 46,187 for the 440G, a roughly 30% overall difference. The 8745HX also sits at the 92nd percentile among all CPUs, while the 440G sits at the 89th.

The Verdict

The data points to a clear workload split. The AMD Ryzen 7 8745HX is the stronger processor for any task that uses multiple cores or sustained throughput. Its 8 cores and 16 threads, combined with a 55W TDP and Dragon Range architecture, deliver consistently higher scores in compression, encryption, math, sorting, and physics. The 8745HX ranks alongside the AMD Ryzen 9 7945HX in average score (60,104 versus 60,099, a 0% delta) and sits just 0.2% ahead of the Intel Core i9-14900F (60,008). That places it in the upper tier of mobile processors in this database.

The AMD Ryzen AI 5 440G, with 6 cores and 12 threads on a 65W TDP, wins only the single-thread tests. Its 4,060 score is 4.5% higher than the 8745HX's 3,879. That suggests newer Zen 5-based cores have a per-thread advantage, but the 440G cannot overcome the 8745HX's raw core count and higher boost clock in multi-threaded work. The 440G's nearest rivals include the Intel Core i9-13900HX (46,098, a 0.2% delta) and the Intel Core Ultra 5 235 (46,062, a 0.3% delta), placing it in a competitive mid-range desktop bracket.

For users prioritizing single-thread responsiveness, light workloads, or tasks that scale poorly across cores, the 440G offers a measurable edge. For anyone running parallel workloads, the 8745HX is the clear choice based on the recorded measurements. The 8745HX also has a higher percentile ranking (92 versus 89), reinforcing its position as the more capable all-around processor in this comparison.

Head-to-Head Benchmarks

The largest single win for the 8745HX comes in the find prime numbers test, where it scores 159 against 90, a 76.7% advantage. This workload often stresses integer throughput and memory bandwidth, and the 8745HX's 32 MB shared L3 cache and 83.2 GB/s memory bandwidth likely contribute to that gap. The 440G has only 8 MB of L3 cache and 89.6 GB/s bandwidth, so the cache deficit appears significant here.

Encryption shows the second-largest margin at 60.8% (21,840 versus 13,585). This workload benefits from the 8745HX's higher core count and 5.10 GHz boost clock. Integer math follows at 40.8% (100,328 versus 71,251), suggesting the 8745HX's Zen 4 cores deliver substantially more integer throughput per clock when all cores are active.

Random string sorting gives the 8745HX a 43% lead (44,494 versus 31,106), which likely reflects both core count and cache hierarchy. Floating-point math shows a 35.6% difference (61,972 versus 45,711), and extended instructions show 33.9% (27,638 versus 20,648). The multithread score, at 34.2% (31,517 versus 23,487), is representative of these individual results.

The data compression test shows a 24.3% gap (363,759 versus 292,735), and physics shows 26.5% (1,681 versus 1,329). These are smaller but still decisive margins.

The 440G's only wins are the two identical single-thread tests, with a 4.5% edge (4,060 versus 3,879). That is a narrow margin, but it appears in both recorded entries, indicating consistency. The 440G's 4.80 GHz boost clock is lower than the 8745HX's 5.10 GHz, yet the Zen 5 architecture still manages a higher single-thread score. This suggests architectural efficiency per clock is better on the 440G, despite the lower clock speed.
