AMD Ryzen 3 7440U vs Intel Core i7-9750H Comparison

The Verdict

The AMD Ryzen 3 7440U is the decisive winner in this matchup, taking 17 of 19 head-to-head benchmarks while the Intel Core i7-9750H manages only two victories. The Ryzen chip wins every Cinebench test by roughly 23% and dominates in encryption, physics, and single-core Geekbench workloads. The Intel part retains narrow leads only in floating-point math and integer math, where its extra two cores and larger L3 cache provide a slight edge. For users prioritizing modern efficiency, newer memory support, and broad application performance, the Ryzen 3 7440U is the clear recommendation. The i7-9750H remains a viable option only for workloads heavily weighted toward raw floating-point throughput, where its 13.1% advantage in that specific PassMark test could matter. The data does not support choosing the Intel chip for general productivity, content creation, or single-threaded responsiveness.

Architecture Differences

The two processors represent different generations and design philosophies. The AMD Ryzen 3 7440U uses the Zen 4 architecture with the Phoenix2 codename, built on a 4 nm TSMC process with 20,900 million transistors on a 137 mm² die. The Intel Core i7-9750H relies on the older Coffee Lake architecture with the Coffee Lake-HR codename, fabricated on Intel's 14 nm process with a 149 mm² die. The node difference explains much of the performance gap: the Ryzen part achieves higher clocks at a much lower 28 W TDP, while the Intel chip requires 45 W to reach lower boost frequencies.

Core configuration differs significantly. The Ryzen 3 7440U has 4 cores and 8 threads, while the i7-9750H has 6 cores and 12 threads. Despite the Intel chip's 50% core advantage, the Ryzen part wins most multi-threaded tests, which indicates the Zen 4 architecture's per-core efficiency more than compensates for the core deficit. Cache layouts also diverge: both share 64 KB L1 per core, but the Ryzen has 1 MB L2 per core versus 256 KB per core on Intel, while the i7-9750H has 12 MB shared L3 versus 8 MB shared on the Ryzen. Memory support differs as well, with AMD using DDR5 on a dual-channel bus at 89.6 GB/s bandwidth, while Intel uses DDR4 at 42.7 GB/s, less than half the bandwidth. ECC memory is supported on the Ryzen but not on the Intel part. PCIe connectivity also differs: the Ryzen offers Gen 4 with 14 lanes from the CPU, while the Intel chip provides Gen 3. The integrated graphics are Radeon 740M on AMD versus UHD 630 on Intel.

Head-to-Head Benchmarks

The Ryzen 3 7440U wins every Cinebench test by a consistent margin of roughly 23%. In Cinebench R15 multi-core, the Ryzen scores 1112 against 904 for the Intel, a 23% delta. The single-core R15 result shows 156 versus 127, a 22.8% delta. Cinebench R20 multi-core gives 4637 versus 3768, a 23.1% delta, and single-core gives 654 versus 531, a 23.2% delta. Cinebench R23 follows the pattern: multi-core 11042 versus 8973, single-core 1558 versus 1266, both at 23.1% deltas. The consistency across all six Cinebench runs indicates a fundamental per-core architecture advantage rather than a workload-specific quirk.

Geekbench results show the Ryzen's single-core strength most clearly. The single-core score of 2003 versus 1349 represents a 48.5% delta, the second-largest margin in the entire comparison. Multi-core Geekbench is closer but still favors AMD: 5806 versus 5323, a 9.1% delta. The single-core gap reflects the combination of higher boost clock (4.70 GHz versus 4.50 GHz) and the much newer Zen 4 microarchitecture executing more instructions per clock.

PassMark data encryption is the largest victory for the Ryzen, with 9215 versus 3756, a 145.3% delta. This suggests the Zen 4 architecture includes significantly more capable cryptographic instructions. PassMark physics also swings heavily toward AMD, with 939 versus 670, a 40.1% delta. Prime number finding shows the Ryzen ahead by 25% (40 versus 32), and extended instructions favor AMD by 12.7% (10356 versus 9187). Multithread performance in PassMark gives the Ryzen a 21.7% win (12991 versus 10671). Random string sorting and single-thread tests show smaller but clear AMD advantages: 8.1% and 8.7% respectively. Data compression is the closest test, with the Ryzen ahead by only 2.2% (153689 versus 150443).

The Intel i7-9750H wins only two tests. PassMark floating-point math shows Intel ahead at 23343 versus 20291, a 13.1% delta, and integer math gives Intel 37822 versus 36758, a 2.8% delta. These wins likely stem from the Intel chip's 6 cores and 12 threads providing additional throughput in math-heavy parallel workloads, even at lower per-core efficiency. However, these two victories do not offset the broader trend: the Ryzen wins 17 of 19 benchmarks, including every Cinebench test, both Geekbench tests, and the majority of PassMark workloads. The benchmark database places both processors at the 69th percentile among all CPUs, yet the Ryzen's average benchmark score of 15682 exceeds the Intel's 14886, a gap of roughly 5%. The data indicates that the Ryzen 3 7440U outperforms the older i7-9750H across most real-world workloads while doing so at a substantially lower TDP.
