AMD Ryzen 3 7440U vs Intel Core i3-10320 Comparison

The Verdict

The recorded benchmark data gives the AMD Ryzen 3 7440U a clear overall victory over the Intel Core i3-10320, with 15 wins out of 17 head-to-head tests. The Intel part takes only two wins, both in the PassMark single-threaded tests. For workloads that lean on multi-core rendering, encryption, or physics simulation, the Ryzen 3 7440U is the stronger choice. For a narrow slice of single-thread PassMark activity, the Core i3-10320 holds a slight edge. The data shows a 30% advantage for AMD in Cinebench multi-core tests across R15, R20, and R23, which is a decisive margin for a 4-core, 8-thread comparison. The Ryzen's average benchmark score of 15682 sits 5.6% above the Intel's 14852, and both CPUs land at the 69th percentile of all CPUs in the database, meaning they compete in the same overall performance tier despite the lopsided head-to-head results.

Architecture Differences

The two processors come from different design eras and process nodes. The AMD Ryzen 3 7440U is built on Zen 4 architecture with the Phoenix2 codename, fabricated by TSMC on a 4 nm process. It integrates 20,900 million transistors on a 137 mm² die. The Intel Core i3-10320 uses Comet Lake architecture, made by Intel on a 14 nm process, with no transistor count or die size recorded in the database.

Both chips have 4 cores and 8 threads, and both share 8 MB of L3 cache. The L1 cache is identical at 64 KB per core. The L2 cache differs: AMD provides 1 MB per core, while Intel provides 256 KB per core. This fourfold difference in L2 capacity per core is a structural advantage for AMD in workloads that benefit from larger per-core caches.

Memory support separates the two significantly. The Ryzen 3 7440U supports DDR5 memory with a dual-channel bus and a recorded memory bandwidth of 89.6 GB/s. The Core i3-10320 supports DDR4 memory, also dual-channel, but with a recorded bandwidth of 42.7 GB/s. That is a 110% bandwidth advantage for AMD on paper, which aligns with its strong showing in data-intensive tests.

Other architectural differences include ECC memory support, which the AMD chip has and the Intel chip lacks. PCIe connectivity also differs: the Ryzen offers Gen 4 with 14 lanes (CPU only), while the Intel offers Gen 3 with 16 lanes (CPU only). The integrated graphics are the Radeon 740M on the AMD side versus UHD Graphics 630 on the Intel side. The AMD part is a mobile chip on AMD Socket FP7 with a 28 W TDP, while the Intel part is a desktop chip on Intel Socket 1200 with a 91 W TDP. The release dates show the Ryzen launched on 2023-05-02, roughly three years after the Intel's 2020-04-29 launch.

Head-to-Head Benchmarks

The Cinebench suite shows the most consistent and largest structural gap. In Cinebench R15 multi-core, the Ryzen scores 1112 against Intel's 855, a 30.1% advantage. The single-core R15 result is 156 versus 120, a 30% gap. Moving to R20, the multi-core scores are 4637 versus 3564 (30.1%), and single-core is 654 versus 503 (30%). Cinebench R23 keeps the same pattern: 11042 versus 8486 in multi-core (30.1%) and 1558 versus 1198 in single-core (30.1%). The consistency of this 30% delta across every Cinebench version indicates a stable per-thread and multi-thread advantage for the Zen 4 architecture.

The PassMark suite reveals a wider spread. The largest single win for AMD comes in data encryption, where the Ryzen scores 9215 against Intel's 3458, a 166.5% advantage. This is the most lopsided result in the entire comparison. Physics simulation also heavily favors AMD at 939 versus 689, a 36.3% delta. Integer math shows an 18.3% gap (36758 versus 31071), and random string sorting shows a 20.5% gap (21479 versus 17821). Prime number finding is 25% faster on AMD (40 versus 32). Extended instructions favor AMD by 11.5% (10356 versus 9284). Data compression is closer at 9.6% (153689 versus 140255), and floating point math is the tightest AMD win at 4.1% (20291 versus 19483). PassMark multi-thread mirrors the Cinebench pattern at 30.1% (12991 versus 9982).

The Intel Core i3-10320's only victories come in PassMark single-thread, where it scores 2841 against AMD's 2614, an 8% advantage. This appears twice in the data with identical results, confirming the measurement. Notably, this single-thread PassMark win does not translate to Cinebench single-core, where AMD leads by 30%. The divergence suggests the PassMark single-thread workload favors the Intel's higher 3.80 GHz base clock and older architecture's specific instruction handling, while Cinebench's render workload responds better to the AMD's Zen 4 efficiency and higher 4.70 GHz boost.

Where Each One Wins

The AMD Ryzen 3 7440U wins in rendering, encryption, physics, integer math, compression, and multi-threaded throughput. The 30.1% multi-core Cinebench advantage makes it the clear pick for CPU-bound creative workloads like video rendering, 3D scene compilation, and batch image processing. The 166.5% encryption advantage is dramatic and relevant for anyone handling full-disk encryption, secure communications, or database encryption tasks. The 36.3% physics win points to better performance in simulation and physics-heavy applications. The 18.3% integer math lead supports general computation and productivity tasks. The 20.5% random string sorting win indicates faster data processing for sorting-heavy workloads. The 9.6% data compression edge covers archiving and file compression scenarios.

The Intel Core i3-10320 wins only in PassMark single-thread, with an 8% margin. This matters for legacy single-threaded applications that rely on high base clocks and do not scale across cores. The 3.80 GHz base clock is the likely contributor here, as it exceeds AMD's 3.00 GHz base by 0.80 GHz. For users running older software that cannot utilize multiple threads effectively, the Intel chip may feel slightly snappier in specific PassMark-style single-thread operations. However, this advantage does not extend to Cinebench single-core, where AMD wins by 30%, so the practical scope of Intel's win is narrow.

Given the 15-to-2 win split, the database points to the Ryzen 3 7440U as the superior processor for nearly every measured workload. The Intel chip retains relevance only for narrowly defined single-thread PassMark scenarios, while the AMD chip dominates in all multi-thread and most single-thread tests. The Ryzen's modern 4 nm process, larger L2 cache, DDR5 bandwidth, and ECC support further reinforce its position as the more capable part in this comparison.
