Intel Core i3-10105 vs Intel Core i7-10750H Comparison

Where Each One Wins

The benchmark data is unusually one-sided in this matchup. Across all 19 recorded head-to-head tests, the Intel Core i7-10750H wins every single one, with zero victories for the Intel Core i3-10105. This is not a case of one chip dominating in certain workloads while the other takes others; the i7-10750H simply outperforms the i3-10105 across every measured category.

The clearest divide appears in multi-threaded and heavily parallel workloads. The i7-10750H leads by roughly 38 to 49 percent in Cinebench multi-core tests, PassMark multithread, physics, integer math, floating point math, and data encryption. These are precisely the workloads that benefit from additional cores and threads, and the i7-10750H has a structural advantage there with 6 cores and 12 threads versus 4 cores and 8 threads on the i3-10105.

For single-threaded and lightly threaded tasks, the margin narrows considerably. In PassMark single-thread, the i7-10750H scores 2625 against 2589 for the i3-10105, a lead of only 1.4 percent. Geekbench single-core shows a 7.4 percent gap (1417 vs 1319). So users who primarily run lightly threaded applications will notice only a modest difference, while those who regularly push all cores will see a much larger performance separation.

The i7-10750H also wins in memory-sensitive tasks. PassMark data compression shows a 30.2 percent advantage (167213 vs 128464), and random string sorting shows a 34.7 percent lead (21416 vs 15899). These results align with the i7-10750H's larger shared L3 cache and higher memory bandwidth, as recorded in the database.

Architecture Differences

Both processors belong to Intel's Core 10th Gen family and share the Comet Lake architecture, but they are distinct variants. The i7-10750H is Comet Lake-H, built for mobile platforms, while the i3-10105 is Comet Lake-R, built for desktop systems. Both use Intel's 14 nm process node and are manufactured by Intel.

The core configuration is the primary differentiator. The i7-10750H offers 6 cores and 12 threads, while the i3-10105 offers 4 cores and 8 threads. Both have the same per-core L1 cache at 64 KB and per-core L2 cache at 256 KB, but the shared L3 cache differs substantially: the i7-10750H has 12 MB shared, the i3-10105 has 6 MB shared. This doubling of L3 cache helps the i7-10750H in workloads that repeatedly access the same data.

Clock speeds tell a nuanced story. The i7-10750H has a base clock of 2.60 GHz and a boost clock of 5.00 GHz. The i3-10105 has a higher base clock of 3.70 GHz but a lower boost clock of 4.40 GHz. The higher base clock on the i3-10105 helps it in sustained single-thread workloads, which explains why the single-thread benchmark margins are so much smaller than multi-thread margins.

Power and platform also differ. The i7-10750H has a TDP of 45 watts and uses Intel BGA 1440, a socket designed for laptops. The i3-10105 has a TDP of 65 watts and uses Intel Socket 1200, a desktop socket. Both support DDR4 memory in dual-channel configuration, but memory bandwidth differs: 46.9 GB/s for the i7-10750H versus 42.7 GB/s for the i3-10105.

Integrated graphics are present on both, with the i7-10750H featuring UHD Graphics and the i3-10105 featuring UHD Graphics 630. Both support PCIe Gen 3 with 16 lanes from the CPU. Neither has an unlocked multiplier, and neither supports ECC memory.

Head-to-Head Benchmarks

The largest single margin in the entire comparison comes from PassMark find prime numbers, where the i7-10750H scores 39 against 20 for the i3-10105, a 95 percent advantage. This test is highly sensitive to integer throughput and cache behavior, and the i7-10750H's combination of more cores and larger L3 cache produces an outsized result.

Data encryption shows a 44.3 percent lead (3930 vs 2723), while PassMark multithread shows a 41 percent lead (11616 vs 8241). PassMark floating point math gives a 39.7 percent advantage (25070 vs 17949), and integer math gives a 39 percent lead (39730 vs 28577). Physics simulation, another multi-threaded workload, shows a 49.9 percent gap (700 vs 467).

Cinebench results are remarkably consistent across versions. R15 multicore shows 979 vs 708, a 38.3 percent lead. R20 multicore shows 4081 vs 2952, a 38.2 percent lead. R23 multicore shows 9718 vs 7029, a 38.3 percent lead. Single-core versions are similar: R15 single-core at 138 vs 99 (39.4 percent), R20 single-core at 576 vs 416 (38.5 percent), and R23 single-core at 1372 vs 992 (38.3 percent).

Geekbench shows a smaller gap. Multicore scores 5574 vs 4325, a 28.9 percent lead. Single-core scores 1417 vs 1319, a 7.4 percent lead. This suggests that Geekbench's workload mix is less dependent on raw core count than Cinebench, though the i7-10750H still wins clearly.

PassMark extended instructions gives a 21.1 percent lead (10470 vs 8648), while data compression shows 167213 vs 128464, a 30.2 percent lead. Random string sorting at 21416 vs 15899 is a 34.7 percent lead. The narrowest margin of all is PassMark single-thread, where 2625 vs 2589 represents just a 1.4 percent difference.

A: The i7-10750H sits at the 68th percentile of all CPUs with an average benchmark score of 13024, while the i3-10105 sits at the 67th percentile with an average score of 12316.

The Verdict

The recorded data makes the decision straightforward for most users. The Intel Core i7-10750H wins all 19 head-to-head benchmarks, with advantages ranging from 1.4 percent in single-thread tests to 95 percent in prime number finding. There is no workload category in the database where the i3-10105 comes out ahead.

For users who run multi-threaded applications, the i7-10750H is clearly the stronger choice. The roughly 38 percent lead across all three Cinebench versions, the 41 percent lead in PassMark multithread, and the 49.9 percent lead in physics simulation all point to substantially better throughput in parallel workloads. The additional 2 cores and 4 threads, plus the doubled L3 cache, drive this advantage.

For users whose workloads are predominantly single-threaded, the choice is less critical but still favors the i7-10750H. The 1.4 percent PassMark single-thread lead and 7.4 percent Geekbench single-core lead are modest, and the i3-10105's higher base clock of 3.70 GHz helps it keep pace in sustained single-thread tasks. Still, the i7-10750H does not lose a single recorded test.

Platform considerations matter. The i7-10750H is a mobile processor on Intel BGA 1440, while the i3-10105 is a desktop processor on Intel Socket 1200. These are not interchangeable platforms, so the choice may be predetermined by whether the system is a laptop or a desktop. Within those constraints, the i7-10750H offers superior performance in every measured benchmark.

The i3-10105 remains a capable desktop part, sitting near the 67th percentile of all CPUs and performing close to the Intel Core i7-6700K in the database's nearest rival comparison, with a 0.6 percent score difference. But against the i7-10750H specifically, the data shows no scenario where it wins.
